摘要:
轴向槽道热管具有较高的传热能力和可靠的运行稳定性,在航空航天和电子领域具有广阔的应用前景。文章针对“Ω”形轴向槽道热管的特点,设计并搭建了专门的加工和实验平台,通过讨论温度分布规律、当量导热系数、热阻和最大传热能力等参数,对成品热管的传热性能进行了研究和分析。结果表明:热管具有良好的动态响应热性;在相同工作温度下,热管的冷热端温差与加热功率的增加呈正向关系;当热管的工作温度升高时,当量导热系数逐渐增大,并随着功率和充液率的升高而升高,而总热阻在加热功率增加时呈下降趋势;随着充液率的增加,热管的最大传热能力增加,但是增幅会趋缓。
Abstract:
The heat pipe with axial grooves has high heat transfer capacity and reliable operation stability. It can be widely used in aeronautic and aerospace engineering and electronic field. In view of the characteristic of the heat pipes with “Ω”-shaped grooves, a special manufacturing and experimental platform has been designed in this article, and with that the thermal characteristics of the heat pipe are investigated experimentally by analyzing performance parameters such as the temperature distribution, equivalent heat conductivity, thermal resistance, and the maximum heat transfer ability. The conclusion is that the heat pipe has a good ability of dynamic response; with the same working temperature, the differences between evaporation section and condensation section increase with the increase of the input power; the equivalent thermal conductivity of heat pipes increases with the increase of working temperature, input power and filling rate; the total resistance of heat pipe reduces with the increase of input power; with the increase of filling rate the maximum heat transport capability increases, and the change amplitudes become more and more smaller.
