본 발명은 실외열교환기에 관한 것으로서, 더욱 상세하게 차량용 히트펌프 시스템에서 냉ㆍ난방 모드 전환 시 냉매의 흐름이 반대로 이루어지는 실외열교환기에 있어서, 냉매 흐름에 따라 발생되는 차압에 의해 개폐가 조절되는 가변배플을 포함하여 형성됨으로써 냉방시보다 난방시 냉매 패스 수가 줄어들도록 형성될 뿐만 아니라, 냉매 흐름 방향에 따라 자유롭게 이동해야 하는 가변배플의 개폐수단이 브레이징 결합 시 중력방향으로 몰리는 클래드에 의해 용접되는 것을 방지할 수 있는 실외열교환기에 관한 것이다.
The present invention relates to an outdoor heat exchanger and, more specifically, relates to an outdoor heat exchanger, wherein when a cooling and heating mode is converted in a heat pump system for a vehicle, the flow of refrigerant is reversely formed. The outdoor heat exchanger is formed to have a variable baffle which is opened and closed by differential pressure generated by the flow of refrigerant. Therefore, compared to cooling, in case of heating, the refrigerant pass number is reduced, and the outdoor heat exchanger prevents an opening and closing means of the variable baffle which is freely moved along a refrigerant flow direction from being welded by a clad pushed to a gravity direction in case of brazing coupling.
