The invention provides a power assembly or a double-drive assembly with a heat exchanger arranged in a shell gap and an electric vehicle of the power assembly or the double-drive assembly. The power assembly comprises a motor controller, a motor, a speed reducer and a heat exchanger. A shell of the motor controller is used for containing the power module, a shell of the motor is used for fixing a stator of the motor and containing a rotor of the motor, and a shell of the speed reducer is used for containing the parallel shaft gear set. A shell of the motor and a shell of the speed reducer are adjacently arranged in the axial direction of the power assembly, a shell of the motor controller is stacked on the shell of the motor and the shell of the speed reducer, and a shell gap formed by the shell of the motor controller, the shell of the motor and the shell of the speed reducer is used for arranging a heat exchanger. According to the heat exchanger, the space of the shell gap is fully utilized. After the heat exchanger is installed, the size of the power assembly is not additionally increased or the size of the power assembly is not increased, the heat exchanger and various shells in the power assembly are compactly arranged, the size of the power assembly is reduced, and installation and arrangement of the power assembly are facilitated.

本申请提供一种壳体空隙布置换热器的动力总成或双驱总成及其电动车辆。动力总成包括电机控制器、电机、减速器和换热器。电机控制器的壳体用于容纳功率模块，电机的壳体用于固定电机的定子和容纳电机的转子，减速器的壳体用于容纳并行轴齿轮组。沿动力总成轴向电机的壳体和减速器的壳体相邻排列，电机控制器的壳体分别层叠于电机的壳体和减速器的壳体，电机控制器的壳体、电机的壳体和减速器的壳体形成的壳体空隙用于布置换热器。本申请中换热器充分利用了壳体空隙的空间。换热器安装后不会额外增加动力总成的尺寸或者减少了动力总成的尺寸的增大量，动力总成中换热器及各种壳体之间排列紧凑，减小了动力总成的尺寸，有利于动力总成的安装布置。
