Method for sealing heat pipe

Abstract

A method for sealing a heat tube with one open end and one closed end features that said open end is radiated by the ionized light beam in inertial gas for activating it, and then squeezed by two pressing parts to become a sealed end. Its advantages are high strength and no leakage.

Description

【Technical field】 [0001] The invention relates to a heat pipe sealing method, in particular to a heat pipe sealing method carried out at normal temperature. 【Background technique】 [0002] With the rapid development of the electronic information industry, the processing capacity of electronic components such as the central processing unit is increasing day by day, and the heat generated is increasing. The heat dissipation module combined with the heat sink and the fan has gradually been unable to meet the heat dissipation requirements, especially for notebook computers. At present, the heat pipe is an important component widely used in heat transfer. The heat pipe can be regarded as a passive heat transfer element with high thermal conductivity. Due to the internal two-phase flow heat transfer mechanism, the heat transfer capacity of the heat pipe is hundreds of times that of copper metal of the same size. When the heat pipe is used as the heat transfer object, it has the a...

Problems solved by technology

However, the combined surface of the sealing end of the heat pipe 1 has an oxide layer and an adsorption layer, which seriously affects the fusion effect and is difficult to be combined into one body. When the heat pipe 1 is subject to a large impact or internal pressure, leakage phenomena such as cracks are likely to occur.

In addition, in this method, after one end of the heat pipe 1 is extruded and cut off, the cut end is then extruded and cut off, and there are more pipe wastes.
