Penetrating support structure and its production

Abstract

The inventive structural support is made of the braided wire or is made of sheet or block material to form a sheet-shaped concave-convex structure with several throughholes by punching, etching, electroplating or electroforming processes. The structural support is combined in the cavity of liquid-vapour two phases cooling assembly and is fit with a capillary structural layer.

Description

technical field [0001] The present invention relates to a penetrable supporting structure and a manufacturing method thereof, in particular to a liquid-vapor two-phase planar heat conduction element used for heat dissipation elements such as heat pipes, flat heat pipes, steam tank heat spreaders, and thin heat spreaders. The flexible support structure in the element has the dual effects of supporting and avoiding expansion and deformation, thereby facilitating the flow of working fluid and achieving high-efficiency heat uniformity or heat dissipation. Background technique [0002] With the increasing function speed of electronic products and the pursuit of light, thin and small volume, the heat dissipation problem of electronic products and components (such as computer CPU) is becoming more and more serious. In order to solve the heat dissipation problem, many passive heat dissipation and heat equalization components have been proposed as solutions to the heat dissipation pr...

Problems solved by technology

[0004] Known patents related to the supporting structure of heat dissipation elements, such as Chinese Invention Patent Application No. 92128413 "Thin Plate Heat Pipe and Its Manufacturing Method", as shown in Fig. , 12 against each other to achieve the purpose of the support structure, the patent also mentions a solid straight groove support structure, as shown in Figure 2, a solid straight groove 21 is formed inside the housing 20 However, the two structures disclosed in the above-mentioned patents all have a common shortcoming, that is, the groove 12 and the solid straight groove 21 block the fluidity of the steam (vapor-phase working fluid), thereby affecting the heat dissipation efficiency

[0005] Another example is China's utility model patent application No. 93220197 "improvement of uniform temperature heat conduction structure", utility model patent application No. 93205027 "heat pipe", utility model patent application No. Application No. 86115415 "Heat Pipe Radiator", Utility Model Patent Application No. 88210055 "Heat Pipe Vapor" and other patents all propose a solid straight groove support structure similar to that shown in Figure 2, so The common disadvantage is that the solid straight groove support structure blocks the flow of steam (vapor-phase working fluid), thus affecting the heat dissipation efficiency

[0006] Another example is China's utility model patent application No. 87222042 "circular heat pipe flattened into flat heat pipe structure (1)", which proposes a section that can be a solid circle or a solid circle with grooves or a hollow circle, square or A square support structure with grooves, reticular capillary tissue or sintered capillary tissue is used to support and provide liquid capillary flow. Referring to Fig. The molds 20, 21 sandwich the pipe body 10 up and down to form a flat heat pipe structure. A serious disadvantage of this structure is that the support body 12 is attached to the capillary tissue 11 at a single point. As shown i
