The present invention guides a portion of a liquid refrigerant circulating a vapor compression cycle to an electric component to cool the electric component, thereby simplifying a configuration of a flow passage since there is no need to have an additional cooling water flow passage. Moreover, the present invention cools by using boiling heat transfer of the liquid refrigerant to more improve cooling performance as compared to a case of using cooling water. In addition, the present invention supplies the refrigerant absorbing waste heat of the electric component during cooling of the electric component as the refrigerant of a high pressure side of the vapor compression cycle so as to more improve a coefficient of performance of the system.

    본 발명은, 증기압축 사이클을 순환하는 액상 냉매 중 일부를 전장부품으로 안내하여 전장부품을 냉각시킴으로써, 별도의 냉각수 유로가 필요하지 않으므로 유로의 구성이 간단해질 수 있을 뿐만 아니라, 액상 냉매의 비등 열전달을 이용하여 냉각시키기 때문에 냉각수를 사용하는 경우에 비해 냉각성능이 보다 향상될 수 있다. 또한, 전장부품을 냉각시키면서 전장부품의 폐열을 흡수한 냉매를 증기압축 사이클의 고압측 냉매로 공급함으로써, 시스템의 성능계수도 보다 향상될 수 있다.
