冷却装置
摘要：
一种冷却HV设备（31）的冷却装置（1）包括：压缩机（12），该压缩机使致冷剂循环；热交换器（14），该热交换器在致冷剂与外部空气之间进行热交换；膨胀阀（16），该膨胀阀使致冷剂减压；热交换器（18），该热交换器在致冷剂与空调用空气之间进行热交换；冷却单元（30），该冷却单元设置在经由膨胀阀（16）在热交换器（14）与热交换器（18）之间流动的致冷剂的路径上，以便利用致冷剂来冷却HV设备（31）；和四通阀（28），该四通阀在从压缩机（12）到热交换器（14）的致冷剂流与从压缩机（12）到热交换器（18）的致冷剂流之间切换。
摘要（英）：

The invention relates to a cooling apparatus (1) that cools an HV device (31). The cooling apparatus (1) comprises: a compressor (12) that circulates a refrigerant; a heat exchanger (14) that performs heat exchange between the refrigerant and outside air; an expansion valve (16) that reduces the pressure of the refrigerant; a heat exchanger (18) that performs heat exchange between the refrigerant and air-conditioning air; a cooling unit (30) disposed on a path of the refrigerant flowing between the heat exchanger (14) and the heat exchanger (18) via the expansion valve (16) in order to cool the HV device (31) by using the refrigerant; and a four-way valve (28) that switches between a refrigerant flow from the compressor (12) to the heat exchanger (14) and a refrigerant flow from the compressor (12) to the heat exchanger (18).
