摘要

1999年5月19日，中国力学研究所国家微重力实验室在8天时间内首次完成了中国“神舟五号”卫星的空间微重力实验，取得了丰硕的数据。空间微重力实验采用NML制造的多层装置。NML采用天津电源研究所的热电冷却器(TEC)作为热控装置，为液池设施提供了三十多种不同的温度梯度。液池最大温差约为40/spl℃，一侧温度为90/spl℃。介绍了液池装置的结构，介绍了TEC的设计思想、工艺和筛选方法，给出了两种TEC的性能和试验数据。实验证明了TEC的设计是合理的。tec具有优异的性能，是高可靠的空间应用电子设备。

Thermoelectric cooler for space microgravity experiment

On May 19, 1999, during eight days the space microgravity experiment in Chinese "SJ-5" satellite was first completed by Nation Microgravity Lab of Institute of Mechanics and fruitful data have been achieved. The space microgravity experiment used the multi-layer facility made by NML. The NML has used thermoelectric cooler (TEC) by Tianjin Institute of Power Sources (TIPS) as thermal control device which supplied more than thirty kinds of different temperature gradient for liquid pool facility. The maximum temperature difference of liquid pool came about 40/spl deg/C, the temperature of one side was 90/spl deg/C. The paper describes the structure of the liquid pool unit, introduces the design considerations, the technology and screen method of TEC, gives the performance and test data of two types of TECs. The experiment has been proven that the design of the TEC is reasonable. The TECs have excellent performances and are high reliable electronic devices for space, applications.
