Problems solved by technology

The capillary force provided by the sintered capillary structure is better than that of the grid and groove capillary structures, but its thermal conductivity and water permeability are poor, and because it must go through high-temperature sintering steps, the tube body is easily softened by high temperature, making The manufacturing process is relatively complicated, which increases the cost

Embodiment Construction

[0023] Please refer to Figure 2A , which is an exploded schematic diagram of a heat pipe according to a preferred embodiment of the present invention. In order to clearly illustrate the structure of the heat pipe of the present invention, it is represented by an exploded schematic diagram. The heat pipe 20 of the present invention includes a pipe body 21 , a capillary structure 22 , a working fluid (not shown) and a cover plate 23 . The tube body 21 has an inner wall 21a, the capillary structure 22 is attached to the inner wall 21a of the tube, and the working fluid is accommodated in the tube body 21 . The tube body 21 can be a hollow tube body. After the capillary structure 22 is formed, a cover plate 23 is added to each end of the tube body to seal, and the working fluid is injected, and the heat pipe 20 is completed by vacuuming. Alternatively, the tube body 21 with one end sealed first can be used to form the capillary structure 22 on the inner wall 21a of the tube, an...

Abstract

A heat tube is composed of a tube body, a capillary structure attached on inner surface of said tube body and the working fluid in said tube body. Said capillary structure is composed of a supporting frame and multiple slot generated by winding a wire material on said supporting frame. Its advantages are high elasticity, high heat conductivity and high penetrability.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a heat pipe with a high-efficiency capillary structure. Background technique [0002] With the advancement of technology, the number of transistors per unit area of ​​electronic components is increasing, resulting in an increase in heat generation during operation. On the other hand, the operating frequency of electronic components is getting higher and higher, and the heat (switch loss) caused by on / off switching when the transistor is working is also the reason for the increase in the heat generation of electronic components. If the heat is not handled properly, the computing speed of the chip will be reduced, and in severe cases, the life of the chip may even be affected. [0003] Since the heat pipe can transmit a large amount of heat over a considerable distance with a small cross-sectional area and temperature difference, and can operate without an external power supply, it can be used witho...
