The invention provides a heat exchanger, a heat exchange system, a household electric appliance and a vehicle. The heat exchanger comprises at least two heat exchange pipes, a first flow collecting pipe and a second flow collecting pipe, the at least two heat exchange pipes communicate and are arranged in parallel, the first flow collecting pipe communicates with one ends of the at least two heatexchange pipes, the second flow collecting pipe communicates with the other ends of the at least two heat exchange pipes, and the circulation areas of the at least two heat exchange pipes are different. According to the heat exchanger, in the same one flow, the circulation areas of some heat exchange pipes are larger than those of other heat exchange pipes, resistance of the heat exchange pipes with the large circulation areas to medium flowing can be reduced, when lubricating oil not dissolved in a refrigerant in media passes through the heat exchange pipes with the large circulation areas, the resistance of the lubricating oil passing through the heat exchange pipes can be reduced, the lubricating oil is prevented from being deposited in the heat exchange pipes, and the heat exchange property of the heat exchanger can be improved.

    本发明提供了一种换热器、换热系统、家用电器和车辆,换热器包括:至少两个换热管,至少两个换热管相连通,且至少两个换热管并联设置;第一集流管,第一集流管与至少两个换热管的一端相连通;第二集流管,第二集流管与至少两个换热管的另一端相连通;其中,至少两个换热管中,至少两个换热管的通流面积不同。本发明提供的换热器,同一流程中,有一些换热管的通流面积大于其他换热管的通流面积,而通流面积大的换热管对介质流动的阻力会减小,从而介质中未溶于冷媒的润滑油通过通流面积较大的换热管时,润滑油通过换热管的阻力会减小,避免其沉积在换热管中,提升换热器的换热性能。
