Thermal Design of Electric Cabinet for Space Cameras
摘要
Abstract
Electric cabinets of space hyperspectral cameras contain high power electric components as well as industrial grade chips that can withstand low temperature. This makes it imperative to develop an appropriate thermal design for such cabinets. In addition to surface black oxidation and filling of the cabinet using materials of high thermal conductivity, we have designed "日"-shaped metal frameworks with high thermal conductivity for each printed circuit board in the cabinet, and added copper sheets on top of the sensitive chips. Modeling was performed using Icepak to evaluate the effectiveness of the thermal design scheme. The simulation results reveal a maximum temperature of 75.6℃, which is less than 85℃. This indicates that our thermal scheme satisfies the requirements of the indicator. In addition, we have performed thermal vacuum tests of the electric cabinet. The experimental results are in good agreement with the simulation results, thereby validating the effectiveness of our thermal design.关键词
