Plate heat-conducting strip of groove pulsating heat pipe and process

Abstract

A heat pipe has the heat conductivity coefficient which is far higher than that of any pure metal materials. However, as a result of a tubular structure of the heat pipe, particularly, in applications, non-ideal contact surfaces of a heat source and the heat pipe and a heat dissipation device and the heat pipe shape exist in a capillary pulsating heat pipe with a smaller diameter to form heat resistance. The invention discloses a plate metal plate strip which is windowed in sections, a plate heat-conducting strip of a groove pulsating heat pipe which is prepared by performing welding, vacuumizing and liquid injecting with another metal plate strip with grooves which are uniformly distributed in a simulating capillary pipeline punched by a mechanical mould in a same volume, as well as a process. The heat-conducting strip not only has a heat-conducting function of the pulsating heat pipe, but also effectively improves the heat resistance in application. The heat-conducting strip can be conveniently segmented to change the dimension by virtue of a simple tool according to length requirements of different occasions applicable.

Description

technical field [0001] The invention belongs to the field of heat conduction of heat pipes, and relates to a grooved pulsating heat pipe flat conduction 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 shapes of heat sources and heat pipes, heat sinks and heat pipes in applications. The thermal resistance formed by the contact surface has become an important bottleneck for 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 deficiencies of the prior art, the ob...

[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 shapes of heat sources and heat pipes, heat sinks and heat pipes in applications. 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 is not as good as that of a single metal heat sink.
