The present invention provides a gas-liquid separator that separates an incoming high-temperature refrigerant into a gaseous refrigerant and a liquid refrigerant by heat exchange with a low-temperature refrigerant, which has been decompressed after extending, and then discharges the refrigerants into the outside, and also provides an automotive heat pump including the gas-liquid separator. The gas-liquid separator comprises: a main body having a sealed shape; and a heat exchanger provided inside the main body to exchange heat between a high-temperature refrigerant flowing into the main body and a low-temperature refrigerant that has been decompressed. On one side of the main body, formed is a first inlet communicating with one end of the heat exchanger and supplying the high-temperature refrigerant to the heat exchanger, and on the other side of the main body, formed are an outlet through which the refrigerant having passed the heat exchanger and a second inlet through which the refrigerant having been discharged through the outlet is introduced into the main body, wherein the outlet and the second inlet are spaced apart from each other. A gaseous refrigerant outlet through which a separated gaseous refrigerant is discharged is formed on an upper surface of the main body, and a liquid refrigerant outlet through which a separated liquid refrigerant is discharged is formed on a lower surface of the main body. Therefore, a sufficient amount of gaseous refrigerant can be obtained by installing the heat exchanger inside the gas-liquid separator and carrying out heat exchange between the high-temperature refrigerant supplied to the heat exchanger and the refrigerant reduced in pressure after passing through the heat exchanger.

    본 발명은 본 발명은 인입되는 고온냉매를 팽창 후 감압된 저온냉매와의 열교환으로 기상 냉매와 액상 냉매로 분리한 후 외부로 배출하는 것으로서, 밀폐된 형상을 가지는 본체; 및 상기 본체의 내부에 구비되어 상기 본체의 유입되는 고온냉매와 감압된 저온냉매를 열교환시키는 열교환기를 포함하며, 상기 본체의 일측면에는 상기 열교환기의 일단과 연통되며 상기 열교환기로 고온냉매를 공급하는 제1유입구가 형성되고, 상기 본체의 타측면에는 상기 열교환기를 통과한 냉매가 배출되는 배출구와, 상기 배출구를 통해 배출된 냉매가 상기 본체의 내부로 유입되는 제2유입구가 이격되게 구비되며, 상기 본체의 상부면에는 분리된 기상 냉매가 배출되는 기상 냉매 배출구가 형성되고, 상기 본체의 하부면에는 분리된 액상 냉매가 배출되는 액상 냉매 배출구가 형성되는 기액분리기 및 이를 포함하는 차량용 히트펌프 시스템을 제공한다. 따라서, 기액분리기의 내부에 열교환기를 설치하여 열교환기로 공급되는 고온냉매와 열교환기를 통과 후 감압된 냉매를 열교환하여 기상냉매를 충분히 확보할 수 있다.
