More Information
Summary:An inverter (300) includes an inverter case (310), a plurality of power modules (340) and a plurality of cooling fins (314). The inverter case (310) includes an annular portion (311), a supporting portion (312) and a cooling liquid flow channel (400). The cooling liquid flow channel (400) is a sealed channel located in the annular portion (311) and the supporting portion (312), and a cooling liquid inlet (317) and an inverter case cooling liquid flow channel outlet (313) are formed on the annular portion (311) at two ends of the cooling liquid flow channel (400). The power module (340) is arranged on the supporting portion (312), and the cooling fins (314) are arranged on the cooling liquid flow channel (400), the fin parts (316) of the cooling fins (314) are respectively extended and arranged inside the cooling liquid flow channel (400), and the contact parts (315) of the cooling fins (314) are respectively extended to contact heat transfer parts (341) of corresponding power modules (340).
