The invention provides a heat exchanger core, an air conditioner heat exchanger and a vehicle. The heat exchanger core comprises a plurality of communicating units which are arranged in a stacked mode and sequentially communicate with one another, and each communicating unit comprises a pipe side part, a loop part and a flat pipe part, wherein the pipe side part and the loop part are oppositely arranged, and the flat pipe part communicates between the pipe side part and the loop part. Moreover, the pipe side part and the loop part are both formed by buckling oppositely arranged laminations, two cavities are defined in the pipe side part, a channel is defined by the loop part, the flat pipe part comprises a first flat pipe and a second flat pipe, the first flat pipe is communicated between one cavity and the channel, the second flat pipe is communicated between the other cavity and the channel, and the first flat pipe is communicated with the second flat pipe. A refrigerant can sequentially flow through the first flat pipe and the channel from one cavity, then flows to the other cavity through the second flat pipe and then flows out. According to the heat exchanger core, the distance between the flat pipes can be reduced, the heat exchange amount under the unit volume can be increased through the compactly-arranged communicating units, the heat exchange efficiency can be improved, and the heat exchange effect can be improved.

    本发明提供了一种热交换器芯体、空调热交换器及车辆,本发明的热交换器芯体包括层叠布置、且依次连通的多个连通单元,各连通单元包括相对布置的管侧部和回路部,以及连通于管侧部与回路部之间的扁管部。并且,管侧部与回路部均由相对布置的叠片扣合而成,管侧部内被限定出两个空腔,回路部限定出通道,扁管部包括第一扁管和第二扁管,第一扁管连通于其一空腔与通道之间,第二扁管连通于另一空腔与通道之间,制冷剂能够由其一空腔依次流经第一扁管和通道后,经由第二扁管流到另一空腔后流出。本发明的热交换器芯体能够减小扁管间距,并且通过排布紧凑的连通单元,也可使单位体积下的换热量增大,而可提高换热效率,改善换热效果。
