随着机载电子元器件体积缩小性能提高,功耗不断增大,散热问题日益严峻,热电制冷技术受到广泛关注,为了掌握热电制冷器的散热性能,设计了热电制冷器散热性能实验测试装置,对热电制冷器的冷却效果和散热性能进行了研究,结果表明热电制冷器的功率与散热性能有密切关系,热电制冷器在使用过程中跟据热源功耗及热端散热能力的不同存在最优功率,为热电制冷器在机载电子元器件散热领域的应用提供了参考依据。

As new refrigeration technology, thermoelectric refrigeration is focused increasingly along with volume reduction,performance advancing as well as power accretion of airborne electronic components. Experiment test device was designed to study the cooling effect and heat dissipation performance of thermoelectric refrigerator in order to obtain its heat dissipation performance.The results showed that the power of thermoelectric refrigerator was closely connected with its heat dissipation performance.An optimum power exists according to the differences between the heat source power and the hot side heat dissipation performance during the usage process of the thermoelectric refrigerator. Reference basis was thus provided for the application of thermoelectric refrigerator in the heat dissipation area of airborne electronic components.
