摘　　要：为满足天舟一号货运飞船(TZ1)蒸发冷凝科学实验的控温需求,采用半导体制冷片(TEC)和泵驱两相回路结合的控温系统实现了冷凝台-5～40℃(±0. 2℃)的控温要求。对TEC和平行流换热器进行了研究,结果表明该系统能够满足环境温度等于30℃工况下的制冷和散热要求。测试结果表明,平行流换热器在地面和在轨的换热相当,说明重力的影响几乎可以忽略。In order to meet the requirements of the evaporation and condensation experiments in Tianzhou-1 cargo spaceship（T Z-1）,the system combining the thermoelectric cooling chip（TEC） with the pumped two-phase loop has realized the condensation stage temperature control requirement of-5-40 ℃（± 0. 2 ℃）. The research on T EC and the parallel flow heat exchanger shows that the system can meet the requirements of the cooling and heat dissipation under the condition of the ambient temperature equal to 30 ℃. The results show that the heat transfer of the parallel flow heat exchanger on the ground and on orbit is comparable,indicating that the effect of gravity is almost negligible.
