摘要

提出了一种使用烧结金属毡作为吸液芯的新型平板热管。搭建了该平板热管传热特性的测试系统

通过试验分析了该平板热管的启动性能、均温性能

以及热负荷、工作倾角等对该平板热管传热特性的影响。结果表明

该平板热管具有很强的散热能力

其当量导热系数可以达到壳体材料导热系数的11.2倍

且具有良好的均温特性。

Abstract

A novel flat heat pipe with sintering metal felt wick was put forward

which has features of high heat dissipation capacity

high permeability

high mechanical strength

and convenient manufacture.The thermal performance of this novel flat heat pipe was experimentally investigated under natural convection cooling condition.The startup performance

temperature uniformity characteristics and effects of heating power and tilt angles on thermal performance of the novel flat heat pipe were also analyzed.The results show that the equivalent thermal conductivity of this novel flat heat pipe can be up to 11.2times higher than that of shell material of the heat pipe.The novel flat heat pipe can also have good temperature uniformity.
