Abstract: Substantial efforts have been focused on developing high altitude long endurance solar-powered unmanned aerial vehicles (LESP UAVs). With increasingly integrated and compact electronic equipment, the demand for effective heat dissipation becomes more critical but challenging. Aiming at LESP UAV’s equipment bay with the cooling capacity demand of 5kW, after the availability of heat sink is analysed, a single-stage and two-stage vapor compression refrigeration cycle based on radiation cooling are proposed. By using thermodynamic analysis and quality estimation, the corresponding quantitative relationship is obtained, and the variation between cooling capacity and power consumption/system weight are calculated. Combined with the engineering application, the suitable conditions of two schemes are given. The results can provide theoretical and engineering guidance for the research in this field, and have good engineering application value.
