The present invention provides a heat exchanger comprising: a compressor which compresses and circulates a refrigerant; a water-cooled condenser which is placed in a line where the compressed refrigerant moves and uses cooling water to cool the high-temperature refrigerant; a heat exchange unit in which the refrigerant condensed in the water-cooled condenser moves; a water-cooled evaporator for cooling the cooling water using the refrigerant that has passed through the heat exchange unit; and an accumulator for gas-liquid separation of the refrigerant moving in the water-cooled evaporator to deliver the gas to the compressor. A first expansion valve is disposed on a line through which the refrigerant moves from the water-cooled condenser to the heat exchange unit, and a second expansion valve is disposed on a line through which the refrigerant moves from the heat exchange unit to the water-cooled evaporator.

    본 발명은 냉매를 압축하여 순환시키는 압축기, 압축된 냉매가 이동하는 라인에 배치되며 냉각수를 이용하여 고온의 냉매를 냉각하는 수냉식 응축기, 상기 수냉식 응축기에서 응축된 냉매가 이동하는 열교환부, 상기 열교환부를 통과한 냉매를 이용하여 냉각수를 냉각하는 수냉식 증발기 및 상기 수냉식 증발기를 이동하는 냉매를 기액분리하여 압축기로 기체를 전달하는 어큐뮬레이터를 포함하며, 상기 수냉식 응축기에서 상기 열교환부로 냉매가 이동하는 라인에는 제1 팽창밸브가, 상기 열교환부에서 상기 수냉식 증발기로 냉매가 이동하는 라인에는 제2 팽창밸브가 배치되는 것을 특징으로 하는 열교환기를 제공한다.
