Description

Can be with the remote heat-conducting block of heat transferred

Technical field

The present invention provide a kind of can be with the remote heat-conducting block of heat transferred, particularly plant structure thus and can improve general heat-transfer superconductive pipe, body and can't allow heat-transfer superconductive pipe, body have more practicality with heat transferred to disappearance at a distance.

Background technology

The present heat abstractor that adopted at computer cpu (CPU) or high thermal source product of industrial circle, be to utilize the pedestal of aluminium material fin (for example the radiator of No. 459469 patent case manufacturing is announced in Taiwan) to be contacted with thermal source mostly with high heat transfer efficient, with with heat absorption and be delivered on the fin of fin, utilize fan to blow out cold air again the heat on the fin is got rid of.

Because the non-general traditional aluminium material fin of high heat that high efficiency CPU produced now can conduct fast, get rid of, thereby to utilize heat transfer efficiency to exceed the heat that one times copper metal conducts CPU approximately than aluminum metal be the another kind selection; Yet, the about 2.7g/cm of the density of aluminum metal ³, and the density of copper metal is 8.93g/cm ³(the copper weight metal of equal volume is about three times of aluminum metal), therefore, if adopt the copper metallic to cause fin fully, then can can't be by landing experiment because of the preponderance of copper, or be contained on the motherboard after causing motherboard to be out of shape long afterwards.The at present so-called on the market aluminium material fin that has at the bottom of the copper, be with the technology of forging and pressing or welding with the copper coin build-in of forming in advance in the base bottom surface of aluminium material fin; The Taiwan patent announcement also belongs to the design of copper coin build-in in the aluminium material fin for No. 459469.

Though the copper coin embedding of little thickness is planted the effect that has lifting heat conductivility under lighter weight condition in the fin of aluminium material, if but can will have more the object of high-termal conductivity matter be combined in the fin of metal material and so on, then more can make the heat conductivility of fin and heat dispersion obtain further lifting.

This case inventor had before once developed a kind of " having the heat radiation module from the body quick conductive ", it is to utilize heat-transfer superconductive pipe, the body that can freely bend to unroll at fin and thermal source contact site and other most positions, utilize the high rate heat transport characteristic of heat-transfer superconductive pipe, the spread heat of thermal source is arrived other position, cooperate radiator fan that fin is blown out cold air in addition, can promote radiating efficiency.

Described heat-transfer superconductive pipe, body are to adopt metal tube, the body (for example copper, aluminium or other metal body) that can freely bend or be out of shape, and manage, the inside filling of body or comprise material with high speed heat-conductive characteristic, for example:

1, inorganic high-temp superconducting compound material, for example: y ba cu o compound (YBCO) superconductor, TBCCO (TBCCO) superconductor, HBCCO (HBCCO) superconductor, BSCCO (BSCCO) superconductor or other inorganic superconducting materials.

2, organic superconductor material, for example: pure water or other organic superconductor material.

3, other can reach the high speed thermally-conductive materials.

It is with the two ends processing sealing of pipe, body, spills body to prevent described Heat Conduction Material; By described metal tube, body and be included in its inner Heat Conduction Material and constitute heat-transfer superconductive pipe, body; The above its applied principle of inorganic high superconductor is the high speed concussion and friction that utilizes pipe, the interior molecule of body to produce when being heated, and allows heat energy pass with the mode Rapid Thermal that fluctuates; Organic high temperature superconducting materia, its applied principle, be the phase change that produces when utilizing the molecule of liquid in the metal tube, body to be heated and flash heat transfer, because of transmission speed very fast, so be called " heat-transfer superconductive pipe, body ", and very short by the transmission time that the hot junction transfers to cold junction because of heat-transfer superconductive pipe, body, so the temperature difference of hot junction and cold junction is very little, can reach best heat-conducting effect.Through experiment confirm, the speed of its heat transfer is about more than five times of copper, and the heat transfer rate of general aluminum metal is more than fast ten times.

Because the inorganic compound of heat-transfer superconductive pipe, body inside is subject to remote hot teach skill art and still can't breaks through, and causes it under the condition of certain diameter, when heat transfer length surpassed a segment distance, heat transfer efficiency promptly declined to a great extent; With diameter 4mm～5mm, length is that 50 centimeters heat-transfer superconductive pipe is an example, and in room temperature was 25 ℃ environment, if the heat source temperature that an end of this heat-transfer superconductive pipe is contacted is 100 ℃, then after 10 minutes, the temperature that is transmitted to the other end was then reduced to 25 ℃; But if with diameter 4mm～5mm, length is that 40 centimeters heat-transfer superconductive pipe is done experiment, in room temperature is 25 ℃ environment, if the heat source temperature that an end of this heat-transfer superconductive pipe is contacted is 100 ℃, then after 10 minutes, the temperature that is transmitted to the other end then still can remain on the high temperature near 98 ℃, and its thermal loss is very little; Diameter is bigger, and the distance that can transmit heat is also long thereupon; The reason and the technology of this kind inorganic compound heat conduction obstacle, scientific circles still can't explain and break through so far.

Therefore, the present invention is can't the conduct far heat for the disappearance that overcomes aforementioned heat-transfer superconductive pipe, body and heat-transfer superconductive pipe, body and improve.

Summary of the invention

The purpose of this invention is to provide a kind of can be with the remote heat-conducting block of heat transferred, its principal character is one of suitable length or a plural number heat-transfer superconductive pipe, body to be incorporated into metal inside with die casting or foundry engieering and after producing heat-conducting block, end with two groups or more heat-conducting block combines to extend its heat conduction length in the mode that series connection overlaps again, feasible inside comprises heat-transfer superconductive pipe, body and has the heat-conducting block of high speed heat-conductive characteristic, heat can be delivered to the more heat-conducting block of far-end by an end.

Another object of the present invention provide a kind of can be with the remote heat-conducting block of heat transferred, it can connect heat-transfer superconductive pipe, body between two groups or more heat-conducting block, reach equally heat to be delivered to the more heat-conducting block of far-end by the heat-conducting block of an end.
