Heat pipe

Abstract

A heat pipe comprises a sealed shell body; the shell body comprises a pipe body and a sealing part connected with one end of the pipe body; the pipe body is made of titanium; the sealing part is made of one of copper, aluminum, stainless steel, mild steel, iron, nickel, tungsten, tantalum, molybdenum, rhenium or niobium, which makes the general weight of the pipe body be relatively light and also can prevent the sealing part from being chapped when sealing processing is performed, thus the heat-conducting property of the heat pipe is influenced.

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, due to the high hardness of titanium, the heat pipe using this material as the shell is prone to cracks during sealing, which will lead to the leakage of vacuum and working fluid in the pipe body, and affect the heat conduction performance of the heat pipe.
