Description

The manufacture method of plate-type heat radiation module

Invention field

The present invention provides a kind of manufacture method of plate-type heat radiation module, particularly relevant for the heat-transfer superconductive pipe that will have high heat transfer character, body and have the manufacture method that the metallic plate of good heat conductive character is combined as a whole, be suitable for any flash heat transfer, heat radiation part of needing with the heat conductivility that promotes plate-type heat radiation module.

Background technology

The present heat abstractor that adopted at computer cpu (CPU) or high thermal source product of industrial circle, it is to utilize the pedestal of the metal fin with high heat transfer efficient to be contacted with thermal source mostly, 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 distributed.

This way no doubt has its effect for the little heat that Small-sized C PU is produced, but can't be effectively and reach radiating effect fast for the more and more fast a large amount of heats that large-scale CPU produced of arithmetic speed, trace it to its cause be the metal base of fin and radiating fin end between exist a segment distance, because fin has only pedestal with the position that thermal source (being CPU) contacts, so the heat that absorbed of pedestal can't be transferred to the end of radiating fin apace, and the root of radiating fin is also inequality with the heat that distal portion is absorbed; In other words, more the heat that is absorbed near the fin root of pedestal the more, more the heat that fin tips absorbed away from pedestal is then fewer, so cause the limited radiating fin of area only can utilize its near metal base the part come distribute heat, therefore, the radiating efficiency of aforementioned conventional heat abstractor can't be caught up with the demand of fast-developing CPU operation efficiency or the heat radiation of high thermal source product really; Therefore,, and whole radiating effect can be strengthened, the more high-order radiating requirements of electronic product can be significantly improved if there is brand-new heat abstractor can break through the shortcoming of traditional heat-dissipating device.

No. 90212712 novel patent application case of being applied for before this case applicant is to solve the existing disappearance of aforementioned conventional heat abstractor: Taiwan patent announcement " heat pipe aluminium sheet processing procedure " that No. 384424 patent provided also provides the scheme that solves; But the applicant thinks that No. 90212712 case of before being applied for still can't contain whole invention theory and execution mode fully, and it is also uneconomical than bothering on processing procedure to announce No. 384424 case.

Summary of the invention

Main purpose of the present invention provides a kind of manufacture method of plate-type heat radiation module, it is that heat-transfer superconductive pipe, body that will have high-termal conductivity matter and the metallic plate with good heat conductive character combine, with the method for the heat conductivility of further lifting plate-type heat radiation module.

Based on this, the manufacture method of plate-type heat radiation module provided by the present invention, at first be to cut out two metallic plates, punch forming goes out corresponding dented space according to the curved shape of heat-transfer superconductive pipe, body with two metallic plates again, then heat-transfer superconductive pipe, body are inserted in the dented space of a metallic plate wherein, placed the metallic plate of heat-transfer superconductive pipe, body in this with another metallic plate is involutory again, bestowed at last and add hot rolling and handle and being finished product after handling with integer.

Manufacture method provided by the present invention has following advantage in comparison with No. 384424 patent case of aforementioned bulletin:

One, handling ease does not need to refill inorganic high-temp superconducting compound material, organic superconductor material or other high speed thermally-conductive materials.

Two, heat-transfer superconductive pipe does not have leakage phenomenon.

Embodiment

Consult Fig. 1 to shown in Figure 3, the manufacture method of plate-type heat radiation module provided by the present invention may further comprise the steps:

B, cut out metallic plate 1;

C, these two metallic plate 1 punch formings are gone out corresponding dented space 11 according to the curved shape of heat-transfer superconductive pipe, body 2;

D, heat-transfer superconductive pipe, body 2 are inserted in the dented space 11 of wherein 1 moulding of a metallic plate;

E, placed the metallic plate 1 of heat-transfer superconductive pipe, body 2 in this with another metallic plate 1 is involutory;

F, bestow and add hot rolling and handle;

G, integer are handled.

H, finished product.

Heat-transfer superconductive pipe wherein, body are to adopt the metal body (for example copper, aluminium or other metal body) that can freely bend or be out of shape, and manage, the inner 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.

By aforementioned manufacture method of the present invention, because this heat-transfer superconductive pipe, body 2 are high duty heat transfer bodies of making in advance, therefore in manufacture method, as long as directly heat-transfer superconductive pipe, body 2 are put between the dented space 11 of two metallic plates 1 after the moulding, giving roll extrusion to two metallic plate 1 when again metallic plate 1 being heated to fusing point is combined as a whole and gets final product, make very simple and easy, the lower and economically valuable of cost.Certainly, because metallic plate 1 is just heating and roll extrusion after heat-transfer superconductive pipe, body 2 are put into its dented space 11, so the material melting point that is used for making heat-transfer superconductive pipe, body 2 must be higher than the fusing point of metallic plate 1, damage heat-transfer superconductive pipe, body when avoiding metallic plate to be heated to fusing point.

And, utilize method of the present invention, also upper and lower metallic plate can be become the shell of machine or facility with heat-transfer superconductive pipe, body heating and roll forming, can directly machine be locked in the machine that can produce heat with shell, make its shell have good heat sinking function.
