Problems solved by technology

Based on the thermodynamic analysis of the redox reaction, if the working fluid filled in the copper heat pipe contains oxygen, the working fluid and the tube wall of the copper heat pipe will undergo an oxidation reaction in the presence of oxygen, which will automatically produce 2Cu+4H + +O 2 →2H 2 O+2Cu 2+ reaction, the inner wall of the copper heat pipe will be oxidized, and the heat pipe will be oxidized and corroded to hinder the conduction of heat, and at the same time reduce the service life of the heat pipe

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Please also refer to figure 1 and figure 2 , figure 1 is a flow chart of the method for processing working fluid in the present invention, figure 2 is a cross-sectional view of an apparatus used in the method for processing a working fluid. The method of treating a working fluid includes the following steps.

[0014] Step 101 , providing a device 1 for processing working fluid, opening the valve 14 , and injecting an appropriate amount of liquid working fluid 11 into the container 10 through the introduction pipe 13 .

[0015] Step 102 , introducing specific gas into the working fluid 11 through the inlet pipe 13 , and simultaneously opening the valve 16 of the outlet pipe. Because the solubility of the gas in the working fluid 11 is fixed at the same temperature, by passing a specific gas, that is, increasing the solubility of the specific gas ...

Abstract

The inventive working-fluid processing method includes the following steps of charging an amount of liquid working fluid into a container and feeding a specific gas into the working fluid to remove oxygen from the working fluid. The invention also provides a heat-pipe manufacturing method. In the process of manufacturing heat-pipe, the working fluid processed by the above method is filled in the copper heat pipe as the working fluid for heat pipes. The working fluid has a very low oxygen content, so it can prevent the heat pipe inner wall from producing the oxidizing reaction.

Description

【Technical field】 [0001] The invention relates to a method for preparing the heat pipe. 【Background technique】 [0002] In recent years, with the rapid development of electronic technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have caused a sharp increase in the heat generation of electronic components per unit volume. Heat dissipation methods in the prior art include heat dissipation fins, heat pipes, and heat conduction interfaces. How to improve heat dissipation efficiency to solve the heat energy emitted by electronic components and prevent damage to electronic components caused by high heat and high temperature due to the increase in the density of integrated circuits has become an important issue today. [0003] The heat pipe is a heat conduction device that relies on the phase change of its internal working fluid to conduct heat. It has high thermal conductivity, excellent isothermal proper...
