摘要:
为满足新型战机在地面待飞时对机载液冷系统的地面保障需求,本文设计开发并试制了飞机地面液冷车,分别对电源动力系统、冷却液输送系统、制冷加热系统(单级蒸汽压缩制冷循环+电加热器)、电气控制系统和车载底盘及厢体5部分进行了实验研究。结果表明:样车实现了液冷车补液、液冷车内循环、液冷车对机载液冷系统的加液/排液和外循环供液保障等功能。在环境温度为5 ℃的外循环制热和30 ℃的外循环制冷时,使机载液冷系统达到设定温度(制热时加热至15 ℃,制冷时冷却至10 ℃),分别需要24min和20 min,冷却液循环流量为200 L/min,温度波动在±0.5℃以内。

Abstract:
To satisfy the ground support requirements of the airborne liquid cooling system for aircraft repair or airport-related training, a new kind of multifunction ground liquid cooling camion for military aircrafts was designed and developed. This camion comprises five main parts, namely power supply system, coolant circulation system, cooling and heating system (single-stage vapor compression refrigeration cycle and electrical heater), electric control system, vehicle chassis, and body. Results showed that the functions of coolant supplementation to the liquid cooling camion, coolant internal circulation in the liquid cooling camion, coolant addition and drain for liquid cooling system on board, and hot/cold coolant external circulation from the liquid cooling camion to the liquid cooling system on board, are achieved in the sample liquid cooling camion. Moreover, the liquid cooling system satisfied the setting temperatures of 15 ℃ and 10 ℃ in the heating and cooling modes after 24 and 20 min, respectively. Accordingly, the environmental temperatures of heating and cooling were 5 ℃ and 30 ℃, whereas the coolant flow was 200 L/min for both modes, with a temperature fluctuation of ±0.5 ℃.
