The invention relates to an outdoor heat exchanger, which comprises a refrigerant heat exchange area and a refrigerant condensation area which are arranged up and down, a liquid storage device is arranged on the same side of the refrigerant heat exchange area and the refrigerant condensation area, the upper end of the liquid storage device communicates with the refrigerant heat exchange area, the lower end of the liquid storage device, the refrigerant condensation area and an external connector are selectively communicated through a three-way reversing valve, a refrigerant inlet is formed in the end, away from the liquid storage device, of the refrigerant heat exchange area, and a refrigerant outlet is formed in the end, away from the liquid storage device, of the refrigerant condensation area. According to the outdoor heat exchanger, the channels of the three-way reversing valve are switched, so that the outdoor heat exchanger can be used as a condenser of an extended-range PHEV type air-conditioning system, can also provide a condenser function for an EV type during refrigeration cycle, and can be used as a space for gasifying and absorbing heat of a condensed refrigerant during heating cycle, therefore, the outdoor heat exchanger can be shared by devices of various types of vehicles, the universality of the outdoor heat exchanger is enhanced, and the product development cost and the vehicle later maintenance cost are saved.

    本发明涉及一种室外换热器,包括呈上下设置的制冷剂换热区与制冷剂冷凝区,所述制冷剂换热区与制冷剂冷凝区的同侧设有储液器,所述储液器的上端与制冷剂换热区连通,储液器的下端、制冷剂冷凝区和外部接口通过三通换向阀可选择地连通,所述制冷剂换热区上背离储液器的一端设有制冷剂进口,所述制冷剂冷凝区上背离储液器的一端设有制冷剂出口。本室外换热器通过切换三通换向阀的通道,使该室外换热器既可作为增程PHEV车型空调系统的冷凝器使用,又可为EV车型提供制冷循环时的冷凝器功能,以及在制热循环时作为冷凝后的制冷剂气化吸热的空间,实现了多种车型的器件共用,增强了室外换热器的通用性,节省了产品开发成本以及车辆后期维修成本。
