摘要
为了开发一种用于空调系统排风能量回收的热管式换热器,设计一种单面槽道板式脉动热管并对其传热性能进行实验研究,分析在空气强制对流冷却条件下冷热段比例、工质、充液率、倾角对其热性能的影响。研究结果表明:热管冷热段轴向长度比例为6:4时,导热性能最好;丙酮工质时的热管传热性能优于水工质的热管传热性能;倾角对其传热性能的影响不大;该热管采用丙酮工质、充液率为20%时具有最高的传热性能及最低的启动温度,适于空调系统排风的能量回收。
In order to develop a kind of heat pipe exchanger used for exhaust energy recovery of air-conditioning system, one kind plate pulsating heat pipe was designed and experimentally investigated. The influence on heat transfer performance of cold and hot length ratio, working liquid, filling ratio and inclination angle was analyzed under the effect of forced air convection cooling conditions. The results show that the heat pipe has the best heat transfer performance when the ratio of cold length and hot length is 6：4, heat transfer performance is better when the working liquid is acetone rather than water, and the effect of inclination angle is very small. Heat pipe has the highest heat transfer performance and the lowest starting temperature when the working liquid is acetone and the filling ratio is 20%, which can be used to exhaust energy recovery of air-conditioning system.
