  • A high power electronic control cabinet for space optical remote sensors was designed according to the design demands of space electronic equipment. Firstly, the thermal design principle was summarized for space electronic equipment. Then, the thermal design process of the electronic cabinet was generalized, the temperature difference of typical high power electronic components was calculated and the thermal design schemes of printed circuit boards and high power electronic components were introduced. Finally, the design schemes were validated by the means of thermal analysis and thermal test. The test results indicate that the thermal balance temperature of the electronic control cabinet is less than 30 ℃ in a stable working state and the shell temperatures of electronic components are under 54.2 ℃, which proves that the design schemes fully meet the design requirements of thermal control.
