Abstract

Abstract

To ensure the operating temperature of electronic controlling cabinet in a space camera to satisfy the operating requirements, the thermal design of large power consumption electronic components in the electronic controlling cabinet was performed according to the design feature and heat transfer path of the controlling cabinet. The key problems such as the great heat-producing capability and long heat transfer path were settled. On the basis of the above, a complete thermal design scheme was given. By taking some classical elements for examples, the effect of heat eliminating was estimated. In the end, a thermal analysis finite element model was established by a finite element thermal analysis software IDEAS-TMG. Based on the given temperature boundary condition, the steady-state thermal analysis of electric cabinet was carried out by the IDEAS-TMG, and the integral thermal response performance of electronic controlling cabinet and the steady-state temperature profiles of PCBs and large power consumption elements were given. It is shown that the ranges of temperatures of PCBs and large power consumption electronic components in steady-state thermal analysis are 40.6-51.1 ℃ and 46.3-62.5 ℃, respectively, which reaches the target of thermal design. Analytical results indicate that the thermal design scheme for the electronic controlling cabinet is appropriate and feasible and it can satisfy the requirement of thermal control operating.
