Abstract: A top-mounted heat dissipation photovoltaic inverter device includes an inverter module and a top-mounted heat dissipation module. The top-mounted heat dissipation module includes a top-installed heat dissipation assembly and a back-mounted heat dissipation assembly. The top-installed heat dissipation assembly includes a condenser and a fan assembly. The back-mounted heat dissipation assembly includes an evaporator and an air-cooled heat sink. The condenser and the box are arranged in a laminated manner in a first direction. The condenser and the fan assembly are arranged adjacently in a second direction. The box, the evaporator, and the air-cooled heat sink are arranged sequentially and adjacently in the second direction. A projection of the top-installed heat dissipation assembly does not overlap with a projection of the back-mounted heat dissipation assembly in a third direction.

Abstract: A power converter includes a housing, a power device, a circuit board, a connection piece, and an inductor apparatus. The power device is installed on the circuit board, and an accommodation cavity is formed in the housing and is configured to accommodate the circuit board and the power device. A through-hole is provided on a surface that is of the housing and that faces the circuit board. The inductor apparatus is completely exposed or partially exposed outside the housing and covers the through-hole. The connection piece extends from the circuit board in the housing to the inductor apparatus, and passes through a surface of the housing to physically connect the inductor apparatus to the housing and electrically connect the power device to the inductor apparatus at the same time.
