Description

温度調整装置１０は、表１に示される「状態I」と「状態II」との２つの状態のうち何れか一方の状態を取るようになっており、温度センサ４６及び４８によって液体４０の飽和温度が検出された場合に、制御装置３２が、この飽和温度が検出された際の状態から他の状態に切り替えるようになっている。
【００５０】
ここで、「状態I」は、磁場発生器１６に磁場を印加させて磁気透過ボックス１４で液体４０が飽和温度まで加熱された場合に、バルブ６２を開いて飽和温度に達した液体４０を磁気透過ボックス１４から発熱器２６へ流動させ、かつ、バルブ６８を閉じて磁気透過ボックス１４から吸熱器２８へ液体４０を流動させることを中断するのに並行して、磁場発生器２２に磁場の印加を中断させて磁気透過ボックス２０で液体４０を冷却し、バルブ６６を閉じて液体４０を磁気透過ボックス２０から発熱器２６へ流動させることを中断し、かつ、バルブ６４を開いて磁気透過ボックス２０から吸熱器２８へ液体４０を流動させる状態である。
【００５１】
これに対して、「状態II」は、磁場発生器２２に磁場を印加させて磁気透過ボックス２０で液体４０が飽和温度まで加熱された場合に、バルブ６６を開いて飽和温度に達した液体４０を磁気透過ボックス２０から発熱器２６へ流動させ、かつ、バルブ６４を閉じて磁気透過ボックス２０から吸熱器２８へ液体４０を流動させることを中断するのに並行して、磁場発生器１６に磁場の印加を中断させて磁気透過ボックス１４で液体４０を冷却し、バルブ６２を閉じて液体４０を磁気透過ボックス１４から発熱器２６へ流動させることを中断し、かつ、バルブ６８を開いて磁気透過ボックス１４から吸熱器２８へ液体４０を流動させる状態である。
【００５２】
このようにして、制御装置３２は、「状態I」と「状態II」とを交互に切り替えるようになっている。
【００５３】
以下に、本発明の第１の実施の形態に係る温度調整装置１０の作用について説明する。
【００５４】
液体４０は、パイプ１０２及びパイプ１０４のそれぞれにポンプ６０によって圧送され、磁気透過ボックス１４及び磁気透過ボックス２０に至る。磁場発生器１６及び磁場発生器２２によって磁気透過ボックス１４及び磁気透過ボックス２０内の磁気作業物質１２、１３に磁場が印加されたり磁気作業物質１２、１３から磁場が取り去られたりすると、磁気作業物質１２、１３では、常温で磁気エントロピーが変化して、磁気熱量効果を生じる。磁気作業物質１２、１３に磁場が印加された場合には、磁気作業物質１２、１３が発熱して液体４０の温度が上昇する。一方、磁気作業物質１２、１３から磁場が取り去られた場合には、磁気作業物質１２、１３が吸熱して液体４０の温度が低下する。この場合において、磁気作業物質１２、１３は細粉状又はメッシュ状とされている。この結果、磁気作業物質１２、１３の表面積が増えるので、磁気作業物質１２、１３と液体４０との接触面積を大きくすることができる。従って、磁気作業物質１２、１３と液体４０との間の熱交換を効率良く行うことができる。
【００５５】
磁気透過ボックス１４及び磁気透過ボックス２０内の液体４０を加熱及び冷却する際において、制御装置３２は、磁気透過ボックス１４内の液体４０を磁気作業物質１２に加熱（冷却）させ、これに並行して、磁気透過ボックス内２０の液体４０を磁気作業物質１３に冷却（加熱）させる。さらに、制御装置３２は、磁気透過ボックス１４（磁気作業物質２０）で飽和温度まで加熱された液体４０を流動させる際には、バルブ６２（バルブ６６）を開いてこの加熱された液体４０を発熱器２６へ流動させ、かつ、バルブ６８（バルブ６４）を閉じてこの加熱された液体を吸熱器２８へ流動させることを中断させる。これに並行して、制御装置３２は、磁気透過ボックス２０（磁気透過ボックス１４）で冷却された液体４０を流動させる際には、バルブ６６（バルブ６２）を閉じてこの冷却された液体４０を発熱器２６に流動させることを中断させ、かつ、バルブ６４（バルブ６８）を開いてこの冷却された液体４０を吸熱器２８に流動させる。このようにして制御装置３２は、「状態I」と「状態II」とを交互に切り替える。この結果、発熱器２６には飽和温度まで加熱された液体４０が供給され、吸熱器２８には冷却された液体４０が供給されることになる。従って、飽和温度まで加熱された液体４０と冷却された液体４０とを分別して発熱器２６、吸熱器２８のそれぞれで液体４０と外気との熱交換を行うことができる。この結果、外気は加熱されたり冷却されたりして、外気の温度が調整される。
【００５６】
このような温度調整装置１０では、磁気透過ボックス１４内の液体４０及び磁気透過ボックス２０内の液体４０の飽和温度は、磁気透過ボックス１４、２０にそれぞれ設けられた温度センサ４６、４８によって検出される。温度センサ４６、４８が液体４０の飽和温度を検出すると、制御装置３２は、「状態I」と「状態II」とを切り替える。このように、飽和温度が温度センサ４６、４８によって検出されるため、液体４０が飽和温度に達したことを検出する精度が向上する。
【００５７】
また、発熱器２６及び吸熱器２８から流動した液体４０は、発熱器２６及び吸熱器２８の下流側に設けられたタンク５８に所定量蓄えられる。このタンク５８に蓄えられた液体４０は、ポンプ６０によって汲み出されて再びパイプ１０２、１０４に圧送される。この結果、液体４０は温度調整装置１０を循環することになり、外気との間で熱交換済みの液体を再利用することができる。
【００５８】
さらに、ファン３４、３６は、それぞれ発熱器２６、吸熱器２８によって熱交換された外気を所定方向へ流動させる。この場合において、ファン３４、３６は、液体４０と外気との熱交換を促進させる。この結果、発熱器２６、吸熱器２８のそれぞれでの液体４０と外気との熱交換を効率良く行うことができる。
【００５９】
ここで、気体を媒体とした従来の温度調整装置では、気体を高圧に圧縮するための圧縮機が必要不可欠となる。この結果、装置にこの圧縮機を設置するための所定の空間を要するため、装置を小型化することが困難となる。この点、本発明の第１の実施の形態に係る温度調整装置１０では、気体を高圧に圧縮するための圧縮機を必要としないため、装置の小型化を図ることができる。またさらに、温度調整装置１０は、気体を高圧に圧縮するための圧縮機が不要であるので、低騒音かつ低振動で装置を駆動することができる。また、温度調整装置１０では、気体を高圧に圧縮するための圧縮機が不要であるため、動力は液体の圧送に（単に液体４０をパイプ１０２、１０４等に流すためだけに）必要なものに限られる。従って、温度調整装置１０は、省エネルギーを図ることができる。
【００６０】
また、温度調整装置１０は、常温で磁気エントロピーが大きく変化するような磁気作業物質１２、１３を使用しているため、超低温等の特殊な温度環境、ひいては超伝導材料を用いた超伝導磁石や強力な磁場を発生する電磁石等の特殊な磁石を不要とし、エネルギーの損失が少ない理想的な温度調整装置を得ることができる。すなわち、温度調整装置１０は、磁気エネルギーを熱エネルギーに変換する熱変換効率を向上させることができる。
【００６１】
以上説明したように、本発明の第１の実施の形態に係る温度調整装置１０は、小型で熱変換効率を向上させることができる。
【００６２】
なお、本発明の第１の実施の形態に係る温度調整装置１０では、温度センサ４６、４８を用いて液体４０が飽和温度に達したことを検出した際に、制御装置３２が、「状態I」と「状態II」とを切り替えるものとしたが、本発明は、これに限らない。温度センサ４６、４８を用いなくとも、磁場発生器１６及び磁場発生器２２が磁場を印加してから液体４０が飽和温度に達するまでの飽和温度到達時間を予め計測しておき、制御装置３２が、飽和温度到達時間毎に「状態I」と「状態II」とを切り替える構成としてもよい。
【００６３】
この場合においては、外気の温度を調整するにあたって、磁場発生器１６、２２が磁場を印加してから磁気透過ボックス１４、２０内の液体４０の温度が飽和温度に達するまでの飽和温度到達時間を予め計測しておき、制御装置３２にこの飽和温度到達時間を設定しておく。その後、外気の温度を調整する際には、制御装置３２が、磁場発生器１６、２２の何れか一方が磁場を印加し始めてから飽和温度到達時間毎に「状態I」と「状態I」とを切り替える。このようにして「状態I」と「状態II」とが切り替えられるため、液体４０が飽和温度に達したことを検出する特別な温度センサ（例えば、上述した温度センサ４６、４８）を不要とすることができる。温度調整装置１０をこのような構成にしても、上述した本発明の第１の実施の形態に係る温度調整装置１０と同様の効果を奏することができる。
（第２の実施の形態）
次に、本発明の第２の実施の形態に係る温度調整装置１０について説明する。なお、上述した本発明の第１の実施の形態と同一構成・同一作用の箇所には、同一符号を付して説明を省略する。
【００６４】
図３に示されるように、本発明の第２の実施の形態に係る温度調整装置１０は、磁場発生器１６、２２に永久磁石８０及びヨーク８２を組み込んでハイブリッド型磁石（永久磁石と電磁石とを組み合わせた磁石）としたものである。
【００６５】
磁場発生器１６、２２の側断面図において、磁場発生器１６、２２の中央部には、矩形状の永久磁石８０が設けられている。永久磁石８０のＮ極８４とＳ極８６とのそれぞれには、磁性材からなる一対の矩形状のヨーク８２の各々が一体的に密着接合されており、これらの永久磁石８０と一対のヨーク８２とは、一体となって略「Ｉ」字状となっている。永久磁石８０は、これらの一対のヨーク８２を介してヨーク４２の左右方向中央上部及び左右方向中央下部に一体的に密着接合されている。
【００６６】
図４（Ａ）に示されるように、このような磁場発生器１６、２２では、励磁コイル４４の電流がオフの場合に、永久磁石８０から放出された磁力線（矢印Ｙを参照。）は、永久磁石８０のＮ極８４から放出されて、永久磁石８０の上方のヨーク８２とヨーク４２との連結部位からヨーク４２の励磁コイル４４側を経て、永久磁石８０の下方のヨーク８２とヨーク４２との連結部位から永久磁石８０のＳ極８６に至るようになっている。すなわち、励磁コイル４４の電流がオフの場合には磁場発生器１６は、永久磁石８０に対して励磁コイル４４側で閉ループ状の磁気回路を構成し、磁気作業物質１２、１３へ磁場を印加しないようになっている。
【００６７】
一方、図４（Ｂ）に示されるように、励磁コイル４４の電流がオンの場合には、永久磁石８０で生じた磁力線（矢印Ｚを参照。）は、励磁コイル４４で発生した磁場（矢印Ｗを参照。）の影響を受けて、永久磁石８０の上方のヨーク８２とヨーク４２との連結部位からヨーク４２の磁気透過ボックス１４、２０側を経て、永久磁石８０の下方のヨーク８２とヨーク４２との連結部位から永久磁石８０のＳ極８６に至るようになっている。すなわち、励磁コイル４４の電流がオンの場合においては、磁場発生器１６、２２は、永久磁石８０に対して磁気透過ボックス１４、２０側で閉ループ状の磁気回路を構成し、磁気作業物質１２、１３に磁場を印加するようになっている。この場合において、磁場発生器１６、２２は、永久磁石８０で発生した磁場と励磁コイル４４で発生した磁場とを重畳させて、永久磁石８０で発生した磁場の強さと励磁コイル４４で発生した磁場の強さとをそのまま加算した強さの磁場を生じさせるようになっている。
【００６８】
以下に、本発明の第２の実施の形態に係る温度調整装置１０の作用について説明する。
【００６９】
励磁コイル４４の電流がオフの場合では、永久磁石８０で生じた磁場は、磁気透過ボックス１４、２２を透過しないため、磁気作業物質１２、１３に磁場が印加されることはない（図４（Ａ））。
【００７０】
一方、励磁コイル４４の電流がオンの場合では、永久磁石８０で生じた磁場に励磁コイル４４で生じた磁場（すなわち、電磁石で生じた磁場）を重畳させることで、永久磁石８０で生じた磁力線の向きが変更される。永久磁石８０で生じた磁力線は、永久磁石８０から見て左回り方向に進み、磁気透過ボックス１４、２０の内部の磁気作業物質１２、１３を通過する。この結果、磁気透過ボックス１４の内部の磁気作業物質１２や磁気透過ボックス２０の内部の磁気作業物質１３に強い磁場を印加する（図４（Ｂ））。従って、本発明の第２の実施の形態に係る温度調整装置１０では、磁場発生器１６、２２が、ヨーク８２に接合された永久磁石８０と、ヨーク４２及び励磁コイル４４からなる電磁石とから構成されているため、例えば、超伝導磁石や強力な磁場を発生する電磁石等の特殊な磁石を用いなくても強い磁場を磁気作業物質１２、１３に印加することができる。
【００７１】
またここで、少なくとも磁場発生器１６、２２の内部、すなわちヨーク４２、８２では、永久磁石８０で発生した磁場や励磁コイル４４で発生した磁場は弱められることがない。この結果、磁場発生器１６、２２で発せられて磁気作業物質１２、１３に印加される磁場は、永久磁石８０で発生した磁場と励磁コイル４４で発生した磁場とを最も効率良く利用したものとなる。従って、温度調整装置１０は、磁気エネルギーを熱エネルギーに変換する熱変換効率をより一層向上させることができる。
【００７２】
以上説明したような本発明の第２の実施の形態に係る温度調整装置１０は、上述した本発明の第１の実施の形態に係る温度調整装置１０と同様の効果を奏することができる。
【００７３】
なお、本発明の第２の実施の形態に係る温度調整装置１０では、温度センサ４６、４８を用いて液体４０が飽和温度に達したことを検出した際に、制御装置３２が、「状態I」と「状態II」とを切り替えるものとしたが、本発明は、これに限らない。温度センサ４６、４８を用いなくとも、磁場発生器１６及び磁場発生器２２が磁場を印加してから液体４０が飽和温度に達するまでの飽和温度到達時間を予め計測しておき、制御装置３２が、飽和温度到達時間毎に「状態I」と「状態II」とを切り替える構成としてもよい。
【００７４】
この場合においては、外気の温度を調整するにあたって、磁場発生器１６、２２が磁場を印加してから磁気透過ボックス１４、２０内の液体４０の温度が飽和温度に達するまでの飽和温度到達時間を予め計測しておき、制御装置３２にこの飽和温度到達時間を設定しておく。その後、外気の温度を調整する際には、制御装置３２が、磁場発生器１６、２２の何れか一方が磁場を印加し始めてから飽和温度到達時間毎に「状態I」と「状態I」とを切り替える。このようにして「状態I」と「状態II」とが切り替えられるため、液体４０が飽和温度に達したことを検出する特別な温度センサ（例えば、上述した温度センサ４６、４８）を不要とすることができる。温度調整装置１０をこのような構成にしても、上述した本発明の第２の実施の形態に係る温度調整装置１０と同様の効果を奏することができる。
（第３の実施の形態）
次いで、本発明の第３の実施の形態に係る温度調整装置１０について説明する。なお、上述した本発明の第１及び第２の実施の形態と同一構成・同一作用の箇所には、同一符号を付して説明を省略する。
【００７５】
図５に示されるように、本発明の第３の実施の形態に係る温度調整装置１０は、空間９２を設け、この空間９２の壁９４の一部を構成するように発熱器２６及び吸熱器２８を対向させて配置し、発熱器２６及び吸熱器２８付近では、発熱器２６及び吸熱器２８の配置箇所を除いて空間９２を気密にしたものである。さらに、この空間９２の内部には、送風機としての１台のファン９０が配置されている。ファン９０は、発熱器２６及び吸熱器２８で加熱及び冷却された外気を空間９２の内部側から外部側に向けて流動させるようになっている。また、このファン９０は、発熱器２６及び吸熱器２８において、液体４０と外気との間の熱交換を促進させる役割を担っている。なお、図５では、説明の都合上、パイプ１０２、１０４、１０６、１０８、及びバルブ６２、６４、６６、６８等を省略して示している。また、図５における矢印付きの破線は、ファン３４によって外気が流動する向きを示している。
【００７６】
以下に、本発明の第３の実施の形態に係る温度調整装置１０の作用について説明する。
【００７７】
外気の温度を調整する際には、発熱器２６、吸熱器２８の内部を液体４０が通過することで、外気と液体４０との間で熱交換が行われる。その後、発熱器２６、吸熱器２８によって熱交換された外気がファン９０によって空間９２の内部側から外部側に向かって流動する。
【００７８】
このような温度調整装置１０では、発熱器２６及び吸熱器２８付近では、発熱器２６及び吸熱器２８の配置箇所を除いて空間９２を気密にしているため、外気は発熱器２６及び吸熱器２８を通過する。この結果、発熱器２６、吸熱器２８で熱交換された外気を空間９２の内部側から外部側に向けて流動させるには、１台のファン９０の駆動で十分となる。従って、温度調整装置１０の部品点数を削減することができる。
【００７９】
また、発熱器２６、吸熱器２８で熱交換された外気を流動させるための動力が、ファン９０の１台分で済むため、温度調整装置１０は、省エネルギーを図ることができる。
【００８０】
以上説明したような本発明の第３の実施の形態に係る温度調整装置１０は、上述した本発明の第１及び第２の実施の形態に係る温度調整装置１０と同様の効果を奏することができる。
【００８１】
なお、本発明の第３の実施の形態に係る温度調整装置１０では、温度センサ４６、４８を用いて液体４０が飽和温度に達したことを検出した際に、制御装置３２が、「状態I」と「状態II」とを切り替えるものとしたが、本発明は、これに限らない。温度センサ４６、４８を用いなくとも、磁場発生器１６及び磁場発生器２２が磁場を印加してから液体４０が飽和温度に達するまでの飽和温度到達時間を予め計測しておき、制御装置３２が、飽和温度到達時間毎に「状態I」と「状態II」とを切り替える構成としてもよい。
【００８２】
この場合においては、外気の温度を調整するにあたって、磁場発生器１６、２２が磁場を印加してから磁気透過ボックス１４、２０内の液体４０の温度が飽和温度に達するまでの飽和温度到達時間を予め計測しておき、制御装置３２にこの飽和温度到達時間を設定しておく。その後、外気の温度を調整する際には、制御装置３２が、磁場発生器１６、２２の何れか一方が磁場を印加し始めてから飽和温度到達時間毎に「状態I」と「状態I」とを切り替える。このようにして「状態I」と「状態II」とが切り替えられるため、液体４０が飽和温度に達したことを検出する特別な温度センサ（例えば、上述した温度センサ４６、４８）を不要とすることができる。温度調整装置１０をこのような構成にしても、上述した本発明の第３の実施の形態に係る温度調整装置１０と同様の効果を奏することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a temperature control device.
[0002]
[Prior art]
As a temperature control technique applied to a refrigeration technique or the like, a heat engine according to the Carnot cycle is generally used. In a heat engine according to the Carnot cycle, gas is confined in a shielded space. For example, a compressor for compressing the gas to a high pressure is operated to change the state of the gas. The gas has a role as a medium between the temperature adjustment target (for example, outside air) and the outside world. When the gas is repeatedly subjected to processes such as compression, heat dissipation, expansion, and heat absorption by the operation of the compressor, the temperature adjustment target Heat is exchanged between the outside and the outside, and the temperature of the temperature adjustment target is adjusted.
[0003]
However, in a heat engine according to such a Carnot cycle, a compressor for compressing gas to a high pressure is indispensable, and a predetermined space is required for installation of this compressor, so it is difficult to downsize the apparatus. There was a drawback of being.
[0004]
By the way, besides the heat engine according to such a Carnot cycle, there is known a temperature adjustment device that adjusts the temperature of the temperature adjustment target using the magnetocaloric effect in a special temperature environment (for example, ultra-low temperature). In such a temperature control device, a gas or a magnetic field generator for applying a magnetic field to the magnetic material is applied without applying a gas or a compressor for compressing the gas to a high pressure. By operating the magnetic field generator and increasing / decreasing the magnetic entropy (amount indicating the degree of alignment of the magnetic moments of the atoms constituting the magnetic material) in a special temperature environment, the magnetic material can dissipate heat. In which the temperature of the temperature adjustment target is adjusted via a medium (generally liquid) between the magnetic substance and the temperature adjustment target in accordance with this (that is, causing a magnetocaloric effect) It is. In such a temperature control device, since a compressor for compressing gas to a high pressure is not required, the size of the device can be reduced (Patent Document 1).
[0005]
Here, such a magnetic material has a property that when the magnetic entropy is greatly increased or decreased in a special temperature environment, the heat dissipation amount (heat generation amount) and the heat absorption amount also increase. In addition, there is a correlation between the increase / decrease width of the magnetic entropy and the strength of the magnetic field applied to the magnetic material. To greatly increase or decrease the magnetic entropy in a special temperature environment such as ultra-low temperature, a strong magnetic field is applied to the magnetic material. Thus, it is necessary to cause a magnetic transformation (phase transition) inside the magnetic material.
[0006]
However, in order to apply a strong magnetic field to a magnetic material under a special temperature environment such as ultra-low temperature, a special temperature environment such as ultra-low temperature is created, and a superconducting magnet using a superconducting material or a strong magnetic field is applied. There was a drawback that special magnets such as generated electromagnets had to be used.
[0007]
By the way, in addition to the heat engine according to the Carnot cycle described above and the temperature adjustment device using the magnetocaloric effect in a special temperature environment, the temperature adjustment target is also made using the thermoelectric conversion of the thermoelectric element (Peltier element) that generates the Peltier effect. There is a temperature adjustment device for adjusting the temperature of the. A Peltier element is an element that emits heat when an electric current is passed. Two types of semiconductors, that is, two types of metals that are connected to each other at two locations (two connection points), or a P-type semiconductor and an N-type semiconductor, are used. Some are alternately connected in series or in parallel. In the Peltier element, when a current flows between two connection points (contact points), a temperature difference occurs between the two connection points (Patent Document 2).
[0008]
In general, a Peltier element made of a semiconductor is used because of the efficiency of thermoelectric conversion. A Peltier element made of a semiconductor has a flat plate shape. One surface is a cooling surface (collection of contacts on a low temperature side) and the other surface is a heat dissipation surface (collection of contacts on a high temperature side). (Hereinafter, unless otherwise specified, “Peltier element” means a Peltier element made of a semiconductor).
[0009]
However, in such a Peltier element, since the cooling surface and the heat dissipation surface are adjacent to each other, it is necessary to suppress heat conduction between the contact on the cooling surface side and the contact on the heat dissipation surface side. Furthermore, it is necessary to increase the electrical conductivity of the Peltier element. Temporarily, by increasing the number of P-type semiconductors and N-type semiconductors to increase the cooling surface and the heat dissipation surface of the Peltier element, an attempt is made to obtain a heat generation amount and a heat absorption amount sufficient for adjusting the temperature of the temperature adjustment target. The electrical conductivity of the Peltier element is lowered, and heat conduction is caused between the cooling surface and the heat radiation surface. For this reason, there is a drawback that it is not preferable to increase the scale of the Peltier element itself.

[Problems to be solved by the invention]
An object of this invention is to provide the temperature control apparatus which can improve heat conversion efficiency small in size in view of the said problem.
[0012]
[Means for Solving the Problems]
  The invention described in claim 1Independent first and second flow paths through which liquid is pumped;
A first magnetic transmission box provided with a first magnetic working material, which is provided in the first flow path and generates heat when a magnetic field is applied and decreases in temperature when the magnetic field is removed; and is provided in the second flow path. A second magnetic transmission box having a second magnetic working material that generates heat when a magnetic field is applied and decreases in temperature when the magnetic field is removed; and a second magnetic transmission box that applies a magnetic field to the first magnetic working material and removes the magnetic field. A first magnetic field generator; a second magnetic field generator for applying a magnetic field to the second magnetic working material; and a second magnetic field generator for removing the magnetic field; and the first flow path downstream of the first magnetic transmission box. A first heat exchanger that exchanges heat between the liquid and the outside air, and is provided downstream of the second magnetic transmission box in the second flow path, between the liquid and the outside air. A second heat exchanger for exchanging heat; and the second magnetic transmission box. A third flow path for flowing liquid that has passed through the first heat exchanger to the first heat exchanger; a fourth flow path for flowing liquid that has passed through the first magnetic transmission box to the second heat exchanger; The first flow path and the fourth flow path on the downstream side of the first magnetic transmission box are opened and closed, and the flow of the liquid that has passed through the first magnetic transmission box is changed to the first heat exchanger or the First switching means for switching to the second heat exchanger, and the second flow path and the third flow path on the downstream side of the second magnetic transmission box are opened and closed, and pass through the second magnetic transmission box. And a second switching means for switching the flow of the liquid to the second heat exchanger or the first heat exchanger.
[0013]
  According to the invention of claim 1,The liquid is pumped to each of the first and second flow paths by a pump.
In addition, a first magnetic transmission box including a first magnetic working material that generates heat when a magnetic field is applied and decreases in temperature when the magnetic field is removed is provided in the first flow path, and further generates heat when a magnetic field is applied. A second magnetic transmission box is provided in the second flow path with a second magnetic working material that drops in temperature when the magnetic field is removed.
Then, when the first magnetic field generator applies a magnetic field to the first magnetic working material in the first magnetic transmission box or removes the magnetic field, the magnetic entropy changes at room temperature in the first magnetic working material. This produces a magnetocaloric effect.
That is, when the first magnetic field generator applies a magnetic field to the first magnetic working material in the first magnetic transmission box, the first magnetic working material generates heat and passes through the first magnetic transmission box. The temperature of the liquid rises. On the other hand, when the magnetic field is removed from the first magnetic working material, the first magnetic working material absorbs heat and the temperature of the liquid passing through the first magnetic transmission box decreases.
Similarly, when the second magnetic field generator applies a magnetic field to the second magnetic working material in the second magnetic transmission box, the second magnetic working material generates heat and passes through the second magnetic transmission box. The temperature of the liquid that rises increases. On the other hand, when the magnetic field is removed from the second magnetic working material, the second magnetic working material absorbs heat and the temperature of the liquid passing through the second magnetic transmission box decreases.
[0014]
  When the heated liquid is flowed to the first heat exchanger and the cooled liquid is flowed to the second heat exchanger, the first magnetic working material in the first magnetic transmission box is transferred to the first heat exchanger by the first magnetic field generator. A magnetic field is applied and the first magnetic working material heats the liquid passing through the first magnetic transmission box. Then, the first switching means opens the first flow path on the downstream side of the first magnetic transmission box and closes the fourth flow path, so that the flow of the liquid that has passed through the first magnetic transmission box is changed to the first flow path. Turn to 1 heat exchanger.
Further, the magnetic field is removed from the second magnetic working material in the second magnetic transmission box by the second magnetic field generator, and the second magnetic working material cools the liquid passing through the second magnetic transmission box. Then, the second switching means opens the second flow path downstream of the second magnetic transmission box, closes the third flow path, and allows the liquid flow that has passed through the second magnetic transmission box to flow through the second magnetic transmission box. Turn to 2 heat exchanger.
[0015]
  Here, in the case of flowing the continuously cooled liquid to the second heat exchanger, the first magnetic field generator removes the magnetic field of the first magnetic working substance in the first magnetic transmission box by the first magnetic field generator, The magnetic working material cools the liquid passing through the first magnetic transmission box. The first switching means closes the first flow path on the downstream side of the first magnetic transmission box and opens the fourth flow path, so that the flow of the liquid that has passed through the first magnetic transmission box is changed to the first flow path. Turn to 2 heat exchanger.
Further, a magnetic field is applied to the second magnetic working material in the second magnetic transmission box by the second magnetic field generator, and the second magnetic working material heats the liquid passing through the second magnetic transmission box. Then, the second switching means closes the second flow path on the downstream side of the second magnetic transmission box to open the third flow path, and the flow of the liquid that has passed through the second magnetic transmission box is changed to the first flow path. Turn to the heat exchanger.
[0016]
  Still further, when the continuously cooled liquid is allowed to flow through the second heat exchanger, the magnetic field is applied to the first magnetic working substance in the first magnetic transmission box by the first magnetic field generator as described above. And the magnetic field of the second magnetic working material in the second magnetic transmission box is removed by the second magnetic field generator. By switching this alternately, the liquid continuously cooled can be supplied to the second heat exchanger.

Among the valves provided in each of the flow paths connected to the other magnetic transmission box, the flow path valve on the first heat exchanger side is opened to allow the liquid that has reached the saturation temperature to flow to the other magnetic field. The flow path from the transmission box to the first heat exchanger and the flow path valve on the second heat exchanger side among the flow path valves connected to the other magnetic transmission box are closed, and the other In parallel with interrupting the flow of the liquid from the magnetic transmission box to the second heat exchanger, the application of the magnetic field to the one magnetic field generator is interrupted and the one magnetic transmission box While cooling the liquid, said one Among the valves provided in each of the flow paths connected to the magnetic transmission box, the flow path valve on the first heat exchanger side is closed to exchange the liquid from the one magnetic transmission box with the first heat exchange.

[0018]
According to the second aspect of the present invention, the liquid is pumped by the pump to each of the independent first and second flow paths to reach the first and second magnetic transmission boxes. A magnetic field is applied to the first and second magnetic working materials in the first and second magnetic transmission boxes by the first and second magnetic field generators, and the magnetic field is removed from the first and second magnetic working materials. If so, in the first and second magnetic working materials, the magnetic entropy changes at room temperature, producing a magnetocaloric effect. When a magnetic field is applied to the magnetic working material, the magnetic working material generates heat and the temperature of the liquid rises. On the other hand, when the magnetic field is removed from the magnetic working material, the magnetic working material absorbs heat and the temperature of the liquid decreases.

In this way, the control device alternately switches between the first state and the second state. As a result, the liquid heated to the saturation temperature is supplied to the first heat exchanger, and the cooled liquid is supplied to the second heat exchanger. Therefore, the liquid heated to the saturation temperature and the cooled liquid can be separated and heat exchange between the liquid and the outside air can be performed in each heat exchanger. As a result, the outside air is heated or cooled, and the temperature of the outside air is adjusted. As the magnetic working substance of the present invention, a compound containing any one element of gadolinium, lanthanum, iron, silicon, or a hydrogen compound thereof is preferable because the magnetic entropy greatly increases or decreases at room temperature. .

Thereafter, when the temperature of the outside air is adjusted, the control device causes the first state and the second state every time the saturation temperature reaches after either one of the first and second magnetic field generators starts to apply the magnetic field. Switch between states. Thus, since the first state and the second state are switched, a special temperature sensor for detecting that the liquid has reached the saturation temperature can be dispensed with.

[0043]
The heat generator 26 and the heat absorber 28 exchange heat between the liquid 40 and the outside air, respectively. In the heat generator 26, the liquid 40 heated by the magnetic working materials 12 and 13 by the magnetic field generators 16 and 22 applying a magnetic field passes through the heat generator 26 and releases heat to the outside air. ing. On the other hand, in the heat absorber 28, the liquid 40 cooled by the magnetic working substances 12 and 13 by the magnetic field generators 16 and 22 interrupting the application of the magnetic field passes through the heat absorber 28 from the outside air.

The tank 58 stores a predetermined amount of the liquid 40 flowing from the heat generator 26 and the heat absorber 28.

The control device 32 determines whether or not the magnetic field generators 16 and 22 apply a magnetic field to the magnetic working material 12 based on the temperature of the liquid 40 in the magnetic transmission box 14 and the temperature of the liquid 40 in the magnetic transmission box 20. Control the opening and closing of the valves 62, 64, 66, and 68 independently.
[0048]
Table 1 below shows possible states of the temperature adjustment device 10.
[0049]
[Table 1]

The temperature adjustment device 10 takes one of the two states “state I” and “state II” shown in Table 1, and the temperature sensor 46 and 48 saturate the liquid 40. When the temperature is detected, the control device 32 switches from the state when the saturation temperature is detected to another state.
[0050]
Here, in the “state I”, when the magnetic field is applied to the magnetic field generator 16 and the liquid 40 is heated to the saturation temperature in the magnetic transmission box 14, the liquid 40 that has reached the saturation temperature by opening the valve 62 is magnetized. In parallel with the flow of the liquid 40 from the transmission box 14 to the heat generator 26 and the interruption of the flow of the liquid 40 from the magnetic transmission box 14 to the heat absorber 28 by closing the valve 68, the magnetic field generator 22 is applied with a magnetic field. , The liquid 40 is cooled in the magnetic transmission box 20, the valve 66 is closed to stop the flow of the liquid 40 from the magnetic transmission box 20 to the heater 26, and the valve 64 is opened to open the magnetic transmission box 20. In this state, the liquid 40 flows from the heat sink 28 to the heat absorber 28.
[0051]
On the other hand, in the “state II”, when the magnetic field is applied to the magnetic field generator 22 and the liquid 40 is heated to the saturation temperature in the magnetic transmission box 20, the liquid 40 that has reached the saturation temperature by opening the valve 66. In parallel with the flow of the liquid 40 from the magnetic transmission box 20 to the heat generator 26 and interrupting the flow of the liquid 40 from the magnetic transmission box 20 to the heat absorber 28 by closing the valve 64. Is interrupted to cool the liquid 40 in the magnetic transmission box 14, close the valve 62 to interrupt the flow of the liquid 40 from the magnetic transmission box 14 to the heater 26, and open the valve 68 to perform magnetic transmission. In this state, the liquid 40 flows from the box 14 to the heat absorber 28.
[0052]
In this way, the control device 32 switches between “state I” and “state II” alternately.
[0053]
Below, the effect | action of the temperature control apparatus 10 which concerns on the 1st Embodiment of this invention is demonstrated.
[0054]
The liquid 40 is pumped by the pump 60 to each of the pipe 102 and the pipe 104 and reaches the magnetic transmission box 14 and the magnetic transmission box 20. When the magnetic field generator 16 and the magnetic field generator 22 apply a magnetic field to the magnetic working materials 12 and 13 in the magnetic transmission box 14 and the magnetic transmission box 20 or remove the magnetic field from the magnetic working materials 12 and 13, the magnetic work is performed. In the substances 12 and 13, the magnetic entropy changes at room temperature to produce a magnetocaloric effect. When a magnetic field is applied to the magnetic working materials 12 and 13, the magnetic working materials 12 and 13 generate heat and the temperature of the liquid 40 increases. On the other hand, when the magnetic field is removed from the magnetic working materials 12 and 13, the magnetic working materials 12 and 13 absorb heat and the temperature of the liquid 40 decreases. In this case, the magnetic working substances 12 and 13 are in the form of fine powder or mesh. As a result, the surface area of the magnetic working substances 12 and 13 is increased, so that the contact area between the magnetic working substances 12 and 13 and the liquid 40 can be increased. Therefore, heat exchange between the magnetic working substances 12 and 13 and the liquid 40 can be performed efficiently.
[0055]
When heating and cooling the liquid 40 in the magnetic transmission box 14 and the magnetic transmission box 20, the control device 32 causes the magnetic working material 12 to heat (cool) the liquid 40 in the magnetic transmission box 14, and in parallel therewith. Then, the liquid 40 in the magnetic transmission box 20 is cooled (heated) by the magnetic working substance 13. Further, when the control device 32 causes the liquid 40 heated to the saturation temperature in the magnetic transmission box 14 (magnetic working material 20) to flow, the control device 32 opens the valve 62 (valve 66) to generate heat. And the valve 68 (valve 64) is closed to interrupt the flow of the heated liquid to the heat absorber 28. In parallel with this, when the control device 32 causes the liquid 40 cooled in the magnetic transmission box 20 (magnetic transmission box 14) to flow, the control device 32 closes the valve 66 (valve 62) and causes the cooled liquid 40 to flow. The flow to the heater 26 is interrupted, and the valve 64 (valve 68) is opened to allow the cooled liquid 40 to flow to the heat absorber 28. In this way, the control device 32 switches between “state I” and “state II” alternately. As a result, the liquid 40 heated to the saturation temperature is supplied to the heat generator 26, and the cooled liquid 40 is supplied to the heat absorber 28. Therefore, the liquid 40 heated to the saturation temperature and the cooled liquid 40 can be separated and the heat exchange between the liquid 40 and the outside air can be performed by the heat generator 26 and the heat absorber 28. As a result, the outside air is heated or cooled, and the temperature of the outside air is adjusted.
[0056]
In such a temperature adjusting device 10, the saturation temperature of the liquid 40 in the magnetic transmission box 14 and the saturation temperature of the liquid 40 in the magnetic transmission box 20 is detected by temperature sensors 46 and 48 provided in the magnetic transmission boxes 14 and 20, respectively. The When the temperature sensors 46 and 48 detect the saturation temperature of the liquid 40, the control device 32 switches between “state I” and “state II”. As described above, since the saturation temperature is detected by the temperature sensors 46 and 48, the accuracy of detecting that the liquid 40 has reached the saturation temperature is improved.
[0057]
Further, the liquid 40 flowing from the heat generator 26 and the heat absorber 28 is stored in a predetermined amount in a tank 58 provided on the downstream side of the heat generator 26 and the heat absorber 28. The liquid 40 stored in the tank 58 is pumped out by the pump 60 and again sent to the pipes 102 and 104 by pressure. As a result, the liquid 40 circulates through the temperature adjusting device 10, and the liquid that has been heat exchanged with the outside air can be reused.
[0058]
Furthermore, the fans 34 and 36 flow the outside air heat-exchanged by the heat generator 26 and the heat absorber 28 in a predetermined direction, respectively. In this case, the fans 34 and 36 promote heat exchange between the liquid 40 and the outside air. As a result, heat exchange between the liquid 40 and the outside air in each of the heat generator 26 and the heat absorber 28 can be performed efficiently.
[0059]
Here, in a conventional temperature control apparatus using a gas as a medium, a compressor for compressing the gas to a high pressure is indispensable. As a result, since a predetermined space for installing the compressor is required in the apparatus, it is difficult to downsize the apparatus. In this respect, the temperature adjustment device 10 according to the first embodiment of the present invention does not require a compressor for compressing gas to a high pressure, and thus the device can be miniaturized. Furthermore, since the temperature adjusting device 10 does not require a compressor for compressing gas to a high pressure, the device can be driven with low noise and low vibration. In addition, since the temperature adjusting device 10 does not require a compressor for compressing the gas to a high pressure, the power is required for pumping the liquid (just for flowing the liquid 40 through the pipes 102, 104, etc.). Limited. Accordingly, the temperature adjustment device 10 can save energy.
[0060]
Moreover, since the temperature adjusting device 10 uses magnetic working substances 12 and 13 whose magnetic entropy changes greatly at room temperature, a special temperature environment such as ultra-low temperature, and thus a superconducting magnet using a superconducting material, A special magnet such as an electromagnet that generates a strong magnetic field is not required, and an ideal temperature adjustment device with little energy loss can be obtained. That is, the temperature adjustment device 10 can improve the heat conversion efficiency for converting magnetic energy into heat energy.
[0061]
As described above, the temperature adjustment device 10 according to the first embodiment of the present invention is small and can improve the heat conversion efficiency.
[0062]
In the temperature adjustment device 10 according to the first embodiment of the present invention, when the temperature sensor 46 or 48 is used to detect that the liquid 40 has reached the saturation temperature, the control device 32 displays “state I”. "And" State II "are switched, but the present invention is not limited to this. Even if the temperature sensors 46 and 48 are not used, the saturation temperature arrival time from when the magnetic field generator 16 and the magnetic field generator 22 apply the magnetic field to when the liquid 40 reaches the saturation temperature is measured in advance. Alternatively, the “state I” and the “state II” may be switched every time the saturation temperature is reached.
[0063]
In this case, when adjusting the temperature of the outside air, the saturation temperature arrival time from when the magnetic field generators 16 and 22 apply the magnetic field until the temperature of the liquid 40 in the magnetic transmission boxes 14 and 20 reaches the saturation temperature is set. The saturation temperature arrival time is set in the control device 32 in advance. Thereafter, when adjusting the temperature of the outside air, the control device 32 sets “state I” and “state I” for each saturation temperature arrival time after one of the magnetic field generators 16 and 22 starts to apply the magnetic field. Switch. Since the “state I” and “state II” are switched in this way, a special temperature sensor (for example, the above-described temperature sensors 46 and 48) that detects that the liquid 40 has reached the saturation temperature is unnecessary. be able to. Even if the temperature adjustment device 10 has such a configuration, the same effects as those of the temperature adjustment device 10 according to the first embodiment of the present invention described above can be obtained.
(Second Embodiment)
Next, a temperature adjustment device 10 according to a second embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the location of the same structure and the same effect | action as the 1st Embodiment of this invention mentioned above, and description is abbreviate | omitted.
[0064]
As shown in FIG. 3, the temperature adjustment device 10 according to the second embodiment of the present invention includes a hybrid magnet (permanent magnet and electromagnet) by incorporating a permanent magnet 80 and a yoke 82 into the magnetic field generators 16 and 22. Magnet).
[0065]
In the sectional side view of the magnetic field generators 16 and 22, a rectangular permanent magnet 80 is provided at the center of the magnetic field generators 16 and 22. A pair of rectangular yokes 82 made of a magnetic material are integrally and closely joined to each of the N pole 84 and the S pole 86 of the permanent magnet 80. The permanent magnet 80 and the pair of yokes 82 are integrally bonded. Is a substantially “I” shape. The permanent magnet 80 is tightly bonded integrally to the upper left and right center and lower left and right center of the yoke 42 via the pair of yokes 82.
[0066]
As shown in FIG. 4A, in such magnetic field generators 16 and 22, the lines of magnetic force (see arrow Y) emitted from the permanent magnet 80 when the current of the exciting coil 44 is off are as follows. It is discharged from the N pole 84 of the permanent magnet 80 and passes through the exciting coil 44 side of the yoke 42 from the connecting portion between the yoke 82 and the yoke 42 above the permanent magnet 80, and the yoke 82 and the yoke 42 below the permanent magnet 80. To the south pole 86 of the permanent magnet 80. That is, when the current of the excitation coil 44 is off, the magnetic field generator 16 forms a closed-loop magnetic circuit on the excitation coil 44 side with respect to the permanent magnet 80 and does not apply a magnetic field to the magnetic working materials 12 and 13. It is like that.
[0067]
On the other hand, as shown in FIG. 4B, when the current of the exciting coil 44 is on, the magnetic lines of force (see arrow Z) generated in the permanent magnet 80 are the magnetic fields (arrows) generated in the exciting coil 44. Under the influence of W.), the yoke 82 and the yoke below the permanent magnet 80 pass from the connecting portion between the yoke 82 and the yoke 42 above the permanent magnet 80 through the magnetic transmission boxes 14 and 20 side of the yoke 42. 42 to the south pole 86 of the permanent magnet 80. That is, when the current of the exciting coil 44 is on, the magnetic field generators 16 and 22 constitute a closed loop magnetic circuit on the side of the magnetic transmission boxes 14 and 20 with respect to the permanent magnet 80, A magnetic field is applied to 13. In this case, the magnetic field generators 16 and 22 superimpose the magnetic field generated by the permanent magnet 80 and the magnetic field generated by the excitation coil 44, and the strength of the magnetic field generated by the permanent magnet 80 and the magnetic field generated by the excitation coil 44. A magnetic field with a strength obtained by adding the strengths of the two as they are is generated.
[0068]
Below, the effect | action of the temperature control apparatus 10 which concerns on the 2nd Embodiment of this invention is demonstrated.
[0069]
When the current of the exciting coil 44 is off, the magnetic field generated by the permanent magnet 80 does not pass through the magnetic transmission boxes 14 and 22, so that no magnetic field is applied to the magnetic working materials 12 and 13 (FIG. 4 ( A)).
[0070]
On the other hand, when the current of the exciting coil 44 is on, the magnetic field lines generated in the permanent magnet 80 are superimposed on the magnetic field generated in the permanent magnet 80 by superimposing the magnetic field generated in the exciting coil 44 (that is, the magnetic field generated in the electromagnet). The direction of is changed. The lines of magnetic force generated by the permanent magnet 80 travel counterclockwise as viewed from the permanent magnet 80 and pass through the magnetic working substances 12 and 13 inside the magnetic transmission boxes 14 and 20. As a result, a strong magnetic field is applied to the magnetic working material 12 inside the magnetic transmission box 14 and the magnetic working material 13 inside the magnetic transmission box 20 (FIG. 4B). Therefore, in the temperature adjustment device 10 according to the second embodiment of the present invention, the magnetic field generators 16 and 22 are composed of a permanent magnet 80 joined to the yoke 82 and an electromagnet composed of the yoke 42 and the excitation coil 44. Therefore, for example, a strong magnetic field can be applied to the magnetic working substances 12 and 13 without using a special magnet such as a superconducting magnet or an electromagnet that generates a strong magnetic field.
[0071]
Here, at least in the magnetic field generators 16 and 22, that is, in the yokes 42 and 82, the magnetic field generated by the permanent magnet 80 and the magnetic field generated by the exciting coil 44 are not weakened. As a result, the magnetic field generated by the magnetic field generators 16 and 22 and applied to the magnetic working materials 12 and 13 is the most efficient use of the magnetic field generated by the permanent magnet 80 and the magnetic field generated by the excitation coil 44. Become. Therefore, the temperature adjusting device 10 can further improve the heat conversion efficiency for converting magnetic energy into heat energy.
[0072]

"And" State II "are switched, but the present invention is not limited to this. Even if the temperature sensors 46 and 48 are not used, the saturation temperature arrival time from when the magnetic field generator 16 and the magnetic field generator 22 apply the magnetic field to when the liquid 40 reaches the saturation temperature is measured in advance. Alternatively, the “state I” and the “state II” may be switched every time the saturation temperature is reached.
[0074]
In this case, when adjusting the temperature of the outside air, the saturation temperature arrival time from when the magnetic field generators 16 and 22 apply the magnetic field until the temperature of the liquid 40 in the magnetic transmission boxes 14 and 20 reaches the saturation temperature is set. The saturation temperature arrival time is set in the control device 32 in advance. Thereafter, when adjusting the temperature of the outside air, the control device 32 sets “state I” and “state I” for each saturation temperature arrival time after one of the magnetic field generators 16 and 22 starts applying a magnetic field. Switch. Since the “state I” and “state II” are switched in this way, a special temperature sensor (for example, the above-described temperature sensors 46 and 48) that detects that the liquid 40 has reached the saturation temperature is unnecessary. be able to. Even if the temperature adjustment device 10 has such a configuration, the same effect as that of the temperature adjustment device 10 according to the second embodiment of the present invention described above can be obtained.
(Third embodiment)
Next, a temperature adjustment device 10 according to a third embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the location of the same structure and the same effect | action as 1st and 2nd embodiment of this invention mentioned above, and description is abbreviate | omitted.
[0075]
As shown in FIG. 5, the temperature adjustment device 10 according to the third embodiment of the present invention includes a space 92 and a heat generator 26 and a heat absorber so as to constitute a part of a wall 94 of the space 92. 28 is arranged to face each other, and in the vicinity of the heat generator 26 and the heat absorber 28, the space 92 is hermetically sealed except for the positions where the heat generator 26 and the heat absorber 28 are arranged. Furthermore, one fan 90 as a blower is disposed in the space 92. The fan 90 allows the outside air heated and cooled by the heat generator 26 and the heat absorber 28 to flow from the inside to the outside of the space 92. The fan 90 plays a role of promoting heat exchange between the liquid 40 and the outside air in the heat generator 26 and the heat absorber 28.

[0077]
When adjusting the temperature of the outside air, the liquid 40 passes through the inside of the heat generator 26 and the heat absorber 28, so that heat is exchanged between the outside air and the liquid 40. Thereafter, the outside air heat-exchanged by the heat generator 26 and the heat absorber 28 flows from the inside of the space 92 toward the outside by the fan 90.
[0078]
In such a temperature control apparatus 10, the space 92 is hermetically sealed except for the location of the heat generator 26 and the heat absorber 28 in the vicinity of the heat generator 26 and the heat absorber 28. Pass through. As a result, it is sufficient to drive one fan 90 in order to cause the outside air heat-exchanged by the heat generator 26 and the heat absorber 28 to flow from the inside to the outside of the space 92. Therefore, the number of parts of the temperature adjusting device 10 can be reduced.
[0079]
Moreover, since the power for flowing the outside air heat-exchanged by the heat generator 26 and the heat absorber 28 is sufficient for one fan 90, the temperature adjustment device 10 can save energy.
[0080]

Even if the temperature sensors 46 and 48 are not used, the saturation temperature arrival time from when the magnetic field generator 16 and the magnetic field generator 22 apply the magnetic field to when the liquid 40 reaches the saturation temperature is measured in advance. Alternatively, the “state I” and the “state II” may be switched every time the saturation temperature is reached.
[0082]
In this case, when adjusting the temperature of the outside air, the saturation temperature arrival time from when the magnetic field generators 16 and 22 apply the magnetic field until the temperature of the liquid 40 in the magnetic transmission boxes 14 and 20 reaches the saturation temperature is set.

Switch. Since the “state I” and “state II” are switched in this way, a special temperature sensor (for example, the above-described temperature sensors 46 and 48) that detects that the liquid 40 has reached the saturation temperature is unnecessary. be able to.
