    • Passive on-board aircraft cooling systems are provided with an evaporator/receiver in heat-exchange relationship with at least one heat source on board the aircraft, the evaporator/receiver containing a liquid phase working fluid which changes state to a vapor phase working fluid in response to heat transfer therefrom from the at least one heat source. First and second condensers are fluid-connected to the evaporator/receiver for receiving vapor phase working fluid from the evaporator/receiver. An aircraft-internal pressurized air supply stream is provided in heat-exchange relationship with the second condenser, and an aircraft-external unpressurized air supply stream is provided in heat-exchange relationship with the first condenser. At least a portion of the vapor phase working fluid transferred to the first and second condensers is thus condensed by heat transfer between the first and second condensers and the unpressurized and pressurized air supply streams, respectively, to thereby form liquid phase working fluid which returns to the evaporator/receiver by virtue of the fluid connection with the first and second condensers.
    • 被动机载飞机冷却系统设置有与飞机上的至少一个热源热交换关系的蒸发器/接收器,蒸发器/接收器包含将状态改变为气相工作流体的液相工作流体 对来自至少一个热源的热量的响应。 第一和第二冷凝器流体连接到蒸发器/接收器,用于从蒸发器/接收器接收气相工作流体。 与第二冷凝器以热交换关系提供飞机内部加压空气供应流,并且与第一冷凝器以热交换关系提供飞机外部未加压空气供应流。 因此,转移到第一和第二冷凝器的气相工作流体的至少一部分分别通过第一和第二冷凝器与未加压和加压的空气供应流之间的热传递而被冷凝,从而形成液相工作流体,其返回到 该蒸发器/接收器借助于与第一和第二冷凝器的流体连接。
