Embodiment Construction

[0025] Figure 4 It is a flow chart of a preferred manufacturing process of the heat pipe of the present invention, which is to first set a screen 20 on the outer surface of a mandrel 10, and then insert this combined component into a heat-conducting shell 30, such as Figure 5 and Image 6 shown. Of course, in this step, the mandrel 10 can also be inserted into the heat-conducting housing 30 first, and then the screen 20 is bonded to the outer surface of the mandrel 10. An operation mode in which the rod 10 is combined with the screen 20 and then inserted into the heat conduction housing 30 .

[0026] Next, fill the fine powder 40 of appropriate density in the gap between the inner wall of the heat conduction shell 30 and the screen 20, in order to facilitate the positioning of the mandrel 10 and prevent the filled powder 40 from leaking out, the bottom of the heat conduction shell 30 The end 31 can be pre-formed into a neck shape, such as Figure 5 As shown, the mandrel ...

Abstract

A heat pipe consists of a heat conduction shell and a capillary structure. Its preparing method includes setting capillary structure in said shell, forming capillary structure by superposing screen mesh layer with particle layer, combining core bar surface with screen mesh, inserting core bar into said shell then filling micro powder in gas between said shell and screen mesh and sintering it with high temperature for obtaining product of heat pipe.

Description

【Technical field】 [0001] The invention relates to a heat pipe for heat transfer using the principle of phase change and a manufacturing method thereof. 【Background technique】 [0002] Due to its small size, the use of phase change latent heat to quickly transport a large amount of heat energy, uniform temperature distribution, simple structure, light weight, no external force, long life, low thermal resistance, long-distance transmission and other characteristics, the heat pipe meets the current heat dissipation requirements of the computer and other fields , so it is widely used to solve the heat dissipation problem. [0003] The driving principle of the heat pipe is to use the saturated working fluid contained in the capillary structure of the evaporation part to absorb the heat of the external heat source and evaporate. Due to the pressure difference generated by the steam, the steam moves quickly to the condensation part of the heat pipe and transfers heat, and finally c...
