    • A refrigerant vapor compression system includes a compressor having a suction port and a discharge port, an air-cooled heat exchanger operatively coupled to the discharge port, a liquid-cooled heat exchanger operatively coupled to the air-cooled heat exchanger, a coolant pump operatively coupled to a liquid coolant inlet conduit of the liquid-cooled heat exchanger, an evaporator heat exchanger unit operatively coupled to the liquid-cooled heat exchanger and the suction port, a coolant pump operatively coupled to the liquid coolant inlet conduit for pumping a liquid coolant, and a controller operatively associated with the liquid coolant inlet conduit for controlling the flow of liquid coolant into the liquid-cooled heat exchanger. In one embodiment, the liquid-cooled heat exchanger comprises a low-profile enclosure defining an interior volume. The enclosure has a liquid coolant inlet port and a liquid coolant discharge port fluidly coupled to the interior volume, and a continuous refrigerant tube sealingly disposed within the enclosure. The refrigerant tube is fluidly isolated from and in heat exchange relationship with the interior volume in which the liquid coolant flows.
    • 制冷剂蒸汽压缩系统包括具有吸入口和排出口的压缩机,可操作地连接到排放口的空气冷却热交换器,可操作地连接到风冷式热交换器的液冷式热交换器,可操作地连接到冷却剂泵 耦合到液冷式热交换器的液体冷却剂入口管道,可操作地耦合到液冷式热交换器和吸入口的蒸发器热交换器单元,可操作地耦合到液体冷却剂入口导管的冷却剂泵,用于泵送液体冷却剂 以及与液体冷却剂入口管道可操作地相关联的控制器,用于控制液体冷却剂流入液冷式热交换器中的控制器。 在一个实施例中,液冷式热交换器包括限定内部容积的薄型外壳。 外壳具有液体冷却剂入口和流体耦合到内部容积的液体冷却剂排出口,以及密封地设置在外壳内的连续制冷剂管。 制冷剂管与液体冷却剂流动的内部容积流体隔离并且与其交换热交换。
