摘要: 在前期设计卫星大功率电子设备地面测试用通风散热系统的基础上,对系统散热性能进行了优化设计,对不同结构参数下电子器件的空气射流强化散热开展了数值仿真.研究结果表明系统中喷嘴出口直径、喷嘴出口至换热面距离、射流倾斜角以及喷嘴出口风速等参数对散热性能均有直接影响,并给出了定量的无量纲参数优化设计结果.该结论也可应用于表面热流密度为1 kW/m2级电子器件散热的优化设计,并为星载大功率电子设备对流式热控系统设计和地面测试提供技术参考.

Abstract: On the base of the preparative stage of ventilation control system design for high power electronic equipment of satellite during ground tests, the study on optimization design of the cooling performance was done, and the numerical simulation was carried out on air jet impingement cooling system with different structural parameters. Results show that the diameter of nozzle, the distance between nozzle and heat surface, the air jet inclination angle and jet velocity directly affect the performance of the cooling system. And the optimization design results on the quantitative non dimensional parameters are analyzed. The study can be used to optimize heat dissipation for electronic equipment with a heat-flux density of about 1 kW/m2, and provide a reference for convection thermal control system design and ground tests for high-power electric equipment of satellite.

Key words: high power electronic equipment, satellite, ventilation cooling, air jet, optimization design
