According to the present invention, an internal heat exchanger (1000) is disposed between a compressor (410) for compressing a sucked refrigerant to discharge the refrigerant to a condenser (420) and an expansion means (430) for throttling the refrigerant condensed by the condenser (420) to supply the refrigerant to a vaporizer, and comprises: a housing (100) forming a space therein, in which the refrigerant discharged from the vaporizer (440) flows; and a tube (200) disposed in the housing (100) and spirally wound along an inner circumferential surface from a center of the housing (100), in which the refrigerant discharged from the condenser (420) flows. Since the internal heat exchanger (1000) according to the present invention reduces noise while the refrigerant discharged from the vaporizer (440) flows in the housing (100), a vehicle can be driven in a quiet environment. Also, since the internal heat exchanger (1000) according to the present invention comprises the spirally wound tube (200), high heat exchange performance can be obtained by a simple structure which occupies a small space.

    본 발명은 흡입된 냉매를 압축시켜 응축기(420)로 토출하는 압축기(410)와 상기 응축기(420)에서 응축된 냉매를 교축시켜 증발기로 공급하는 팽창수단(430) 사이에 구비되며, 내부에 상기 증발기(440)에서 토출된 냉매가 유동되는 공간을 형성하는 하우징(100); 상기 하우징(100) 내부에 구비되되, 상기 하우징(100) 중심으로부터 내주면을 따라 나선형태로 감겨지며 내부에 상기 응축기(420)에서 토출된 냉매가 유동되는 튜브(200)를 포함한다. 본 발명의 내부 열교환기(1000)는 상기 증발기(440)에서 토출된 냉매가 상기 하우징(100) 내부를 유동하면서 소음이 저감되기 때문에, 차량의 운전 중 정숙성을 높일 수 있다. 또한, 본 발명의 내부 열교환기(1000)는 튜브(200)가 나선형태로 감기는 형태이기 때문에, 부피를 작게 차지하는 간단한 구성으로도, 높은 열교환 성능을 얻을 수 있는 장점이 있다.
