Description

本発明は、熱交換器の樹脂製タンクであって、耐圧性が高く且つ軽量化を図ったものに関する。   The present invention relates to a resin tank for a heat exchanger, which has high pressure resistance and is lightweight.

自動車のエンジン冷却水冷却用熱交換器は、そのタンクに樹脂製のものを多く使用している。この樹脂製タンクは、ガラス繊維と６-６ナイロンその他を使用し、射出成形により製造される。
その横断面は、図２に示す如くＵ字状に形成され、その対向平面が平行となる一対の平行部５と、その一対の平行部５間を連結する半円形部８と、平行部５の端部に段付き状に形成された環状の小フランジ部２とを有する。さらに、タンク本体の内面にはその長手方向に定間隔に離間して、リブ７が一体に突設形成されている。
そして全体は、一端開口の細長い箱状に形成され、その小フランジ部がチューブプレート３の周縁部の環状溝にシールリング９を介して嵌着され、そのチューブプレート３の縁部が小フランジ部２にカシメ固定されたものである。そのチューブプレート３には多数のチューブ６が貫通されている。 Many heat exchangers for cooling engine coolant of automobiles are made of resin in the tank. This resin tank is manufactured by injection molding using glass fiber, 6-6 nylon and others.
The cross section is formed in a U-shape as shown in FIG. 2, a pair of parallel portions 5 whose opposing planes are parallel, a semicircular portion 8 connecting the pair of parallel portions 5, and the parallel portion 5. And an annular small flange portion 2 formed in a stepped shape at the end portion of each. Further, ribs 7 are integrally formed on the inner surface of the tank body so as to be spaced apart at regular intervals in the longitudinal direction.
The whole is formed in an elongated box shape having an opening at one end, and the small flange portion is fitted into the annular groove on the peripheral edge portion of the tube plate 3 via the seal ring 9, and the edge portion of the tube plate 3 is the small flange portion. 2 is caulked and fixed. A number of tubes 6 are passed through the tube plate 3.

特開平１０−２８１６８６号公報JP-A-10-281686

特に、自動車用熱交換器はその軽量化および材料費の低減等によるコストダウンが強く望まれている。そして、樹脂製タンク本体が比較的高価な樹脂材料を使用するので、軽量化とコストダウンのため薄肉化の傾向にある。
しかしながら、その樹脂製タンク本体の薄肉化により耐圧強度が低下するという新たな問題が生じ、そのため図２に示すようなリブ７を一体に突設していた。しかしながら、そのリブ７自体も軽量化及び材料費の低減に逆行することになる。
そこで本発明は、かかる問題点を解決することを課題とする。 In particular, automotive heat exchangers are strongly desired to reduce costs by reducing the weight and reducing material costs. And since the resin tank body uses a relatively expensive resin material, it tends to be thinned for weight reduction and cost reduction.
However, a new problem has arisen that the pressure-resistant strength decreases due to the thinning of the resin tank body, and therefore ribs 7 as shown in FIG. However, the rib 7 itself goes against weight reduction and material cost reduction.
Accordingly, an object of the present invention is to solve such problems.

本発明の熱交換器の樹脂製タンクは、一端側が開口された細長い箱状で且つ横断面Ｕ字状に形成されたタンク本体(1)と、そのタンク本体(1)の開口縁外面に段付き状に一体に突設された環状の小フランジ部(2)と、を具備し、その小フランジ部(2)の外周がチューブプレート(3)の外周縁に被嵌されて、かしめ固定される熱交換器の樹脂製タンクにおいて、
前記小フランジ部(2)の近傍を除き、タンク本体(1)の横断面は、各部の曲率半径が先端程小になる半楕円形部(4)に形成され、そのタンク本体(1)の内面には補強リブが存在しないように形成されたことを特徴とする熱交換器の樹脂製タンクである。 The resin tank of the heat exchanger according to the present invention includes a tank body (1) formed in an elongated box shape having an open end and a U-shaped cross section, and a stepped outer surface of the tank body (1). An annular small flange portion (2) integrally projecting in an attached shape, and the outer periphery of the small flange portion (2) is fitted on the outer peripheral edge of the tube plate (3) and fixed by caulking. In the resin tank of the heat exchanger
Except for the vicinity of the small flange part (2), the cross section of the tank body (1) is formed in a semi-elliptical part (4) in which the radius of curvature of each part decreases toward the tip, and the tank body (1) It is a resin tank of a heat exchanger characterized in that the inner surface is formed with no reinforcing ribs.

本発明の熱交換器の樹脂製タンクは、小フランジ部２の近傍を除きタンク本体１の横断面は、各部の曲率半径が先端ほど小になる半楕円形部４に形成されているから、耐圧性に優れたものとなる。即ち、半楕円形部４の存在により、内圧が加わってもその対向壁面が外側に開くのを抑制し得る。
また、タンク本体１の内面には補強リブが存在しないから、その分だけ軽量化できることになる。 Since the resin tank of the heat exchanger of the present invention is formed in the semi-elliptical portion 4 in which the cross section of the tank body 1 except the vicinity of the small flange portion 2 has a smaller radius of curvature at each end, Excellent pressure resistance. That is, the presence of the semi-elliptical portion 4 can suppress the opposing wall surface from opening outward even when an internal pressure is applied.
Further, since there are no reinforcing ribs on the inner surface of the tank body 1, the weight can be reduced accordingly.

次に、図面に基づいて本発明の実施の形態につき説明する。
図１は本発明の熱交換器の樹脂製タンクの要部横断面図である。
この樹脂製タンクは、その横断面形状に特徴がある。即ち、図２の従来型タンクと異なる点は、小フランジ部２の近傍を除き、タンク本体１の横断面は各部の曲率半径が先端に行くほど小になる半楕円形部４に形成されている。そしてそのタンク本体１の内面には、補強リブが存在しないものである。なお、その肉厚ｂ，幅ａおよび高さｄは従来型の樹脂製タンクのそれらｇ，ｆ，ｈと同一である。
また、この例においてはタンク本体１と小フランジ部２との付け根部分は、その対向面が互いに平行に形成されている。 Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of an essential part of a resin tank of a heat exchanger according to the present invention.
This resin tank is characterized by its cross-sectional shape. That is, the difference from the conventional tank of FIG. 2 is that, except for the vicinity of the small flange portion 2, the cross section of the tank body 1 is formed into a semi-elliptical portion 4 in which the radius of curvature of each portion decreases toward the tip. Yes. Further, no reinforcing rib is present on the inner surface of the tank body 1. The wall thickness b, width a, and height d are the same as those g, f, and h of the conventional resin tank.
In this example, the base portions of the tank main body 1 and the small flange portion 2 are formed so that the opposing surfaces thereof are parallel to each other.

（作用）
エンジン冷却水冷却用熱交換器は、図示しないプレッシャバルブがタンク本体に設けられ、内部を流通する冷却水を加圧し、冷却水の沸点を高くし熱交換を促進している。そのため加圧された樹脂製タンク内は、その内圧によりタンク本体１の対向面間が広がる方向に圧力が加わる。ところが、本発明の樹脂製タンクは、小フランジ部２の近傍を除きタンク本体１の横断面の各部の曲率半径が、先端ほど小になる半楕円形部４に形成されているため、従来型タンクの図２の半円部８に比べて内圧に対する剛性が強くなる。即ち、タンク本体１の対向平面が内圧によって広がり難くなっている。そして、その内面にはリブが存在しないから、その分だけ軽量化が可能である。
なお、他の構成は図２のそれと同一であるので重複する説明を省略する。 (Function)
In the heat exchanger for cooling the engine coolant, a pressure valve (not shown) is provided in the tank body, pressurizing the coolant flowing through the inside, increasing the boiling point of the coolant, and promoting heat exchange. Therefore, pressure is applied in the pressurized resin tank in a direction in which the space between the opposing surfaces of the tank body 1 spreads due to the internal pressure. However, since the resin tank of the present invention is formed in the semi-elliptical part 4 in which the radius of curvature of each part of the cross section of the tank body 1 except the vicinity of the small flange part 2 becomes smaller toward the tip, Compared with the semicircular portion 8 of FIG. That is, the opposing plane of the tank body 1 is difficult to spread due to the internal pressure. Since there are no ribs on the inner surface, the weight can be reduced accordingly.
Since the other configuration is the same as that of FIG. 2, a duplicate description is omitted.
