A double-layer pulsating heat-conducting plate belt and its process

Abstract

A heat tube has the thermal conductivity much higher than that of any pure metal material; due to the tubular structure of the heat tube, especially a capillary pulsation heat tube with a smaller diameter, and the presence of non-ideal contact surfaces between a heat source and the heat tube and between a heat-dissipation device and a heat tube shape in the application, the formation of thermal resistance has become an important bottleneck in the popularization and application of the heat tube. A solution with high degree of mechanization and low cost is adopted in the invention to produce a double-layer pulsation heat-conducting plate strip; the plate strip realizes double-layer pulsation heat-conduction, is efficient and safe, and is convenient to be divided to change the length according different application occasions.

Description

technical field [0001] The invention belongs to the field of heat conduction of heat pipes, and relates to a double-layer pulsating heat conduction plate belt and a process. Background technique [0002] The heat pipe has a thermal conductivity much higher than any pure metal material, but due to its tubular structure, especially the capillary pulsation heat pipe with a smaller diameter, there are non-ideal contacts between the heat source and the heat pipe, the heat sink and the shape of the heat pipe in the application. Surface, and the formation of thermal resistance has become an important bottleneck in the popularization and application of heat pipes. Therefore, in practical applications, it is difficult for heat pipes to exert their maximum efficiency. The heat conduction device used as a heat sink sometimes even has an overall heat conduction effect that cannot catch up with a single metal heat sink. Contents of the invention [0003] In order to overcome the defici...

Therefore, in practical applications, it is difficult for heat pipes to exert their maximum efficiency. Sometimes even the overall heat conduction effect of heat sinks can not catch up with single-metal structure heat sinks.
