The invention relates to a double-sided heat dissipation power module, a motor controller thereof and a vehicle. The double-sided heat dissipation power module comprises a fixing plate assembly, heat dissipation needles, a direct current assembly, an alternating current assembly, a signal lead, a waterproof assembly, a plastic package material and a sealing box body, and the heat dissipation needles are fixedly arranged on the upper surface and the lower surface of the fixing plate assembly; the direct-current assembly is fixedly arranged on the left side of the fixing plate assembly. The AC assembly is fixedly arranged on the right side of the fixing plate assembly. The signal lead is fixedly arranged on the right side of the fixing plate assembly; the waterproof assemblies are clamped on the left and right sides of the fixing plate assembly; the plastic packaging material is fixedly arranged on the front and rear sides of the fixing plate assembly and comprises a sealing box body and a shunting sealing piece. The beneficial effects of the invention are that: 1, heat dissipation is carried out through the double-sided heat dissipation power module, so that the service life of an electrical part is prolonged; 2, the sealing of the double-sided heat dissipation power module is completed through the sealing box body; 3, the cooling liquid is shunted through the shunting sealing element, so that the cooling efficiency is improved; and 4, the design is reasonable, the production and manufacturing cost is reduced, and the production and manufacturing efficiency is improved.

    本发明涉及一种双面散热功率模块及其电机控制器和车辆,包括固定板组件、散热针、直流组件、交流组件、信号引线、防水组件及塑封料、密封盒体,散热针固定设于固定板组件的上下两面;直流组件固定设于固定板组件左侧;交流组件固定设于固定板组件右侧;信号引线固定设于固定板组件右侧;防水组件卡设于固定板组件左右两侧;塑封料固定设于固定板组件前后两侧,包括密封盒体及分流密封件。本发明的有益效果在于:1、通过双面散热功率模块进行散热,增加了电气件的使用寿命;2、通过密封盒体完成对双面散热功率模块的密封;3、通过分流密封件对冷却液进行分流,提升了冷却效率;4、设计合理,降低了生产制造成本,提升了生产制造的效率。
