Problems solved by technology

However, when the heat pipe is sealed, it is necessary to flatten the inner wall at the nozzle to a state of close contact with each other to achieve the sealing effect. However, due to the high hardness of titanium, heat pipes using this material as the shell are relatively Cracks are likely to occur during the flattening process with large deformation, which will lead to the vacuum degree in the tube body and the leakage of working fluid, which will affect the thermal conductivity of the heat pipe

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0010] Such as figure 1 and figure 2 As shown, the heat pipe 10 includes an airtight casing 11 in which a proper amount of working fluid (not shown) is encapsulated, and a capillary structure 12 is provided on the inner wall of the casing 11 .

[0011] The casing 11 includes a tube body 110 and a support body 120 disposed inside one end of the tube body 110 .

[0012] The tube body 110 is made of lightweight titanium. The cross section of the tube body 110 is circular. The tube body 110 includes a cylindrical body 111 and a shrinking tube portion 112 formed at one end of the body 111 . The narrowing portion 112 includes a tapering portion 113 connected to the main body 111 , an extension portion 114 connected to the tapering portion 113 , and a sealing portion 115 formed at the end of the extension portion 114 . The tapered part ...

Abstract

A heat pipe comprises a sealed shell, wherein the shell comprises a pipe body. One end of the pipe body is provided with a sealing part. The pipe body is made of titanium. A supporter is contained in the sealing part. The supporter is made of copper, aluminum, stainless steel, low-carbon steel, iron, nickel, tungsten, tantalum, molybdenum, rhenium or niobium. The whole weight of the heat pipe is light and the fissure caused by over large deformation when processing the sealing part is prevented, so as to protect the thermal conductivity of the heat pipe.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a heat pipe with light weight and good sealing effect. Background technique [0002] At present, heat pipes are widely used in heat dissipation of electronic components with large heat generation due to their fast heat transfer speed. Existing heat pipes usually use copper with high thermal conductivity as the shell, but with the emergence of multi-functional and ultra-thin electronic products, the requirements for the performance and light weight of heat dissipation devices are also increasing. Titanium with thermal conductivity and light weight has become the goal pursued by people as the shell of the heat pipe. However, when the heat pipe is sealed, it is necessary to flatten the inner wall at the nozzle to a state of close contact with each other to achieve the sealing effect. However, due to the high hardness of titanium, heat pipes using this material as the shell are relatively Cracks are ...
