The invention relates to an aircraft engine bleed air liquid cooling system and an aircraft comprising the system. The air-entraining and liquid-cooling system for the aircraft engine comprises an evaporation refrigeration unit, a secondary refrigerant distribution unit and one or more cooling units, wherein the evaporation refrigeration unit provides the cooling capacity of a refrigerant according to the evaporation circulation principle, and conveys the cold refrigerant to the secondary refrigerant distribution unit, so that heat exchange is carried out on the cold refrigerant and a liquid secondary refrigerant in the secondary refrigerant distribution unit, and cooling of the liquid secondary refrigerant is achieved; the secondary refrigerant distribution unit conveys the cooled liquid secondary refrigerant to the one or more cooling units so as to exchange heat with the entrained air in the one or more cooling units to cool the entrained air, and the entrained air cooled by the one or more cooling units is conveyed to the corresponding one or more user subsystems. According to the technical scheme, the precooler has the following beneficial technical effects that the entrained air cooling capacity of the engine can be improved, and the design size of the precooler is prevented from being too large.
本发明涉及飞机发动机引气液冷系统及包括该系统的飞机。该飞机发动机引气液冷系统包括蒸发制冷单元、载冷剂分配单元、以及一个或多个冷却单元;其中,蒸发制冷单元通过蒸发循环原理提供制冷剂的冷量,并将冷的制冷剂输送至载冷剂分配单元,从而与载冷剂分配单元内的液态载冷剂进行换热以实现对液态载冷剂的冷却,载冷剂分配单元将冷却后的液态载冷剂输送至一个或多个冷却单元,从而与一个或多个冷却单元内的引气进行换热以实现对引气的冷却,经一个或多个冷却单元冷却的引气输送至相应的一个或多个用户子系统。根据上述技术方案,本发明能起到以下有益技术效果:能提高对发动机引气冷却的能力,避免预冷器设计尺寸过大。
