The present disclosure relates to a potting adhesive, including: a component A and a component B, the component A including a first liquid organic adhesive containing dimethyl siloxane, the component B including a second liquid organic adhesive containing methyl hydrogen siloxane and silicone oil, at least one of the component A and the component B further including ceramic particles which are spherical particles with a particle size of 0.1 mm to 3 mm. The present disclosure further relates to a heat dissipation device, including an adhesive potting groove, a transformer provided in the adhesive potting groove, and a filling medium which fills and is consolidated in a gap between the transformer and the adhesive potting groove.

Potting adhesive and heat dissipation device

Electrical bus bar

The present disclosure provides a power module, a power module assembly and an assembling method thereof. The power module assembly includes a housing, a resilient bracket, a circuit board, a power device and a fastening unit. The housing includes a first heat-dissipation surface. The resilient bracket is pre-fastened on the housing. The resilient bracket is located near the first heat-dissipation surface and configured with the first heat-dissipation surface to form an accommodating space. The circuit board is configured to assemble on the housing. The power device is plugged in the circuit board and accommodated in the accommodating space. The fastening unit is pre-fastened on the housing and pressing the resilient bracket. While the resilient bracket pushes against the power device, the power device is attached to the first heat-dissipation surface.

Power module, power module assembly and assembling method thereof

A power conversion apparatus is provided, which comprises a housing, a mother board, a first electromagnetic filtering board, a second electromagnetic filtering board, a signal board, a capacitor board, and a heat-dissipation module. The housing includes a heat-dissipation wall and a coolant runner. The mother board is disposed upon the housing and comprises a first surface facing the housing and a power device. The heat-dissipation module includes an thermal conductive insulating sheet adhered to the heat-dissipation wall and an elastic clamp. When the mother board approaches the housing to clamp the power device in the accommodating space between the elastic clamp and the thermal conductive insulating sheet, the power device is pressed against by the elastic clamp and thus adhered to the thermal conductive insulating sheet, so that the power device is thermally coupled to the heat-dissipation wall and the coolant runner via the thermal conductive insulating sheet.

Power conversion apparatus including a heat-dissipation module

The present disclosure provides a power module assembly and an assembling method thereof. The power module assembly includes a housing, a circuit board, at least one resilient set, at least two power devices, and at least one fastening unit. The housing includes at least one heat-dissipation surface. The at least one resilient set is disposed between the housing and the circuit board and includes at least one resilient piece. Each resilient piece includes a base section and two pushing fingers, so as to form an M-word shape or a bird-wings shape. The fastening unit is disposed between the two power devices, connected to the base section of the resilient piece and configured to drive the base section of the resilient piece, so that the two pushing fingers of the resilient piece push against the two power devices respectively and the two power devices are attached to the heat-dissipation surface.

Power module assembly and assembling method thereof

A power conversion apparatus is provided, which comprises a housing, a mother board, an electromagnetic filter board, a signal board, and a heat-dissipation module. The housing includes a first heat-dissipation wall and a coolant passage. The mother board is disposed upon the housing, and comprises a first surface facing the housing and a first power device. The heat-dissipation module includes a first insulated heat-conducting sheet adhered to the corresponding first heat-dissipation wall and a first elastic clamp. When the first surface of the mother board approaches the housing to clamp the first power device within the accommodating space, the first power device is pressed against by the first elastic clamp and thus adhered to the first insulated heat-conducting sheet, so that the first power device is thermally coupled to the first heat-dissipation wall and the coolant passage via the first insulated heat-conducting sheet.

Power conversion apparatus

A battery charging apparatus for an electric vehicle (EV) or a hybrid electric vehicle (HEV) includes a case chassis, a circuit board and at least one electronic component. The case chassis includes a plurality of side plates, a bottom plate and a receptacle. The circuit board is accommodated within the receptacle of the case chassis. The electronic component includes a passive component body with a plurality of conductive wires and a fixing member for accommodating the passive component body. The conductive wires are electrically connected to the circuit board. The fixing member is fixed on at least one of the side plates and the bottom plate of the case chassis.
