A flat plate heat pipe with arrayed microchannels

Abstract

The present invention proposes a flat plate heat pipe with arrayed microchannels, including heat conduction microchannel plate heat pipes and heat uniform microchannel plate heat pipes. The pipeline axis of the heat pipe is perpendicular to the pipeline axis of the uniform heat microchannel flat heat pipe. The heat uniform microchannel plate heat pipe of the present invention is designed with a heat pipe with heat uniform function, which can make the heat pipe use under the condition of higher heat flux density, increase the heat exchange area and improve the efficiency.

Description

technical field [0001] The invention relates to phase change heat transfer and heat exchange technology, in particular to a flat plate heat pipe with arrayed microchannels. Background technique [0002] In the common microchannel flat heat pipe, each microchannel is independently closed, and the vapor and liquid phases move in reverse at high speed in the same tiny channel, resulting in a large interface frictional shear force, which hinders the return of the liquid at the condensation end, making the The heat transfer resistance of the heat pipe increases, and the heat transfer efficiency decreases. Moreover, the commonly studied microchannel flat heat pipes have microchannels along the axial direction, and the axial direction of the heat pipe has very high heat conduction efficiency. When the micro-channel flat heat pipe is used in a relatively high heat flux condition, the excessively high local heat transfer efficiency is very low, making the local temperature of the he...

Problems solved by technology

When the micro-channel flat heat pipe is used in a relatively high heat flux condition, the excessively high local heat transfer efficiency is very low, making the local temperature of the heat pipe very high, and the working medium at the corresponding position inside is easy to dry up, or even burn out Heat pipe
