    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.
