Abstract

This application provides a photovoltaic inverter. The photovoltaic inverter includes a housing, a circuit board, and a power conversion circuit. Internal space of the housing is separated into a plurality of accommodating cavities. The plurality of accommodating cavities include a first accommodating cavity. A switch transistor of the power conversion circuit is located in the first accommodating cavity, and an electronic component is disposed between the switch transistor and a terminal panel. At least one heat dissipation fin is disposed on an outer surface that is of a housing body and that is away from a cover body. Each heat dissipation fin extends in a direction perpendicular to the terminal panel, and is disposed opposite to the switch transistor. A height of the at least one heat dissipation fin in a direction perpendicular to the outer surface is constant. After the photovoltaic inverter is mounted, the heat dissipation fin is located between the housing body and a mounting surface. Therefore, when airflow flows along the heat dissipation fin, the airflow passes through the flat outer surface of the housing body without being blocked by the housing body, thereby improving heat dissipation effect.
