Experimental Investigation on the Properties of an Aluminous Flat Plate Heat Pipe

制造了一台铝基平板热管原理样机,并搭建了测试装置。利用该测试装置对样机的特性进行了系统性的实验研究。实验表明,热管对温度响应迅速,能够快速地实现温度平衡;200 W功率时,冷热面上的温差仅为0.87℃和1.37℃。随着热流密度的增加,热管温度均匀性的优势变得更加明显,热阻仅为0.100℃/W。该热管样机具备优秀的启动性能、均温性能和良好的传热性能。

An aluminous flat plate heat pipe prototype was manufactured and a test device was built for the prototype. The properties of the prototype were experimentally investigated by using the test device. The experimental results showed that the heat pipe had quick response to temperature and could realize temperature equilibrium rapidly. For the power of 200 W, the temperature differences on cooling surface and heating surface were only 0.87 ℃ and 1.37 ℃respectively. With the increase of heat flux, the advantages of temperature evenness of the heat pipe became more evident. Its thermal resistance was only 0.100℃ /W. This heat pipe prototype had excellent starting performance, temperature evenness and heat transfer performance.
