摘　　要：搭建一种单管强化传热的新型测试装置,能应用于干式蒸发、管内冷凝、管外蒸发和管外冷凝。分析了9.52mm,长度为3.4m的内螺纹铜管在蒸发温度分别是5℃和10℃,冷凝温度分别是35℃和40℃时,制冷剂R22、R410A的传热系数,结合实验原理,说明本装置可以完成对不同制冷剂的单管传热性能的测试,为高效换热管的开发提供依据。Building a new test device of heat transfer performance in the enhanced tube,it can be used for the vaporing and con- densing in tube, the vaporing and condensing outside tube. Heat transfer coefficient of refrigerant R22 and R410A was analysed in a inner threaded copper pipe with Ф9.52mm,3.4m of length, when the evaporation temperature is separately 5℃and 10℃, the condensing temperature is separately 35 ℃ and 40 ℃. Combined with the experimental principle, this device can be performed on the heat transfer test of the enhanced tube in different refrigerants, it provides basis for the development of the enhanced tube.
