The invention relates to the field of vehicle-mounted air conditioners, in particular to a condensation heat exchanger and a vehicle. The condensing heat exchanger comprises at least two rows of heat exchange core bodies which are arranged front and back, the heat exchange core body in the most front row is used for being arranged windward, and heat exchange channels of any two adjacent rows of heat exchange core bodies are communicated. In every two adjacent rows of heat exchange core bodies, the rear row of heat exchange core bodies are first-pass heat exchange core bodies allowing refrigerants to pass first, and the front row of heat exchange core bodies are second-pass heat exchange core bodies allowing the refrigerants to pass later. When heat dissipation is carried out, a refrigerant with the high temperature firstly dissipates heat in the rear row of heat exchange core bodies, then a refrigerant with the low temperature flows to the front row of heat exchange core bodies to dissipate heat, and then heated air flows through the rear row of heat exchange core bodies with the high temperature, so that the front row of heat exchange core bodies and the rear row of heat exchange core bodies can dissipate heat to a certain degree, heat dissipation is more uniform, and the heat dissipation efficiency is improved. Therefore, the problem that cooling air in the double-row heat exchanger flows from front to back, and a refrigerant also flows from the front row of heat exchange core bodies to the rear row of heat exchange core bodies, so that heat dissipation of the heat exchange core bodies is not uniform is solved.
本发明涉及车载空调领域,尤其涉及一种冷凝换热器及车辆。冷凝换热器,包括至少两排前后布置的换热芯体,最前排的换热芯体用于迎风布置,任意相邻的两排换热芯体的换热通道连通,相邻两排换热芯体中的后排换热芯体为供制冷剂先通过的先通换热芯体、前排换热芯体为供制冷剂后通过的后通换热芯体。在进行散热时,较高温度的制冷剂首先在后排换热芯体进行散热,之后温度较低的制冷剂流到前排换热芯体进行散热,之后被加热的空气再流经温度较高的后排换热芯体,这样前后两排换热芯体都能得到一定程度的散热,散热更加均匀,进而解决双排换热器中冷却空气从前向后流动而制冷剂也从前排换热芯体向后排换热芯体流动导致换热芯体散热不均匀的问题。
