摘　　要：利用高温相变材料储热、同时用重力热管作为能量传输元件这一高效偶合装置在生产和生活中有广阔的应用前景，本文在实验基础上建立一个考虑自然对流影响的相变传热与热管传热相偶合的传热模型，并对该模型进行数值计算，通过与实验结果进行的对比，证实所建立的模型与所采用的计算方法均是合理可行的。A high efficiency coupled device, whch high temperature phase change medium is used to store heat ener-gy, while two-phase closed thermosyphon is used as the transfer part,will be widelv used in the future. Basedon a series of experirnents,a coupled heat transfer model considering natural convection about phase changeheat transfer and two-phase closed heat transfer is founded. The position and shape of interface arenumerically calculated.Fine agreement between the nurnerical and experimental results shows that the modeland numerical investigations are feasible.
