Claim of US Patent No. 10,660,243

1. A power conversion apparatus, comprisinga housing comprising a coolant runner and at least one heat-dissipation wall thermally coupled to the coolant runner;
a mother board disposed upon the housing and comprising
a first surface facing the housing; and
at least one power device disposed on the mother board and comprising a first face and a second face;
a first electromagnetic filtering board disposed upon the housing and electrically connected to the mother board;
a second electromagnetic filtering board disposed upon the housing and electrically connected to the mother board;
a signal board disposed upon the housing and electrically connected to the mother board;
a capacitor board disposed upon the housing and electrically connected to the mother board; and
a heat-dissipation module comprising
at least one thermal conductive insulating sheet, adhered to the at least one heat-dissipation wall; and
at least one elastic clamp, fixed to the housing and opposite to the at least one thermal conductive insulating sheet, so that an accommodating space is defined by the elastic clamp and the at least one thermal conductive insulating sheet,
wherein when the mother board approaches the housing to clamp the power device in the accommodating space between the elastic clamp and the at least one thermal conductive insulating sheet, the power device is pressed against by the elastic clamp at the first face and thus adhered to the at least one thermal conductive insulating sheet at the second face, so that the power device is thermally coupled to the at least one heat-dissipation wall and the coolant runner via the at least one thermal conductive insulating sheet.
