Abstract

A photovoltaic-inverter heat-dissipation assembly is disclosure and includes a front housing-base, a rear cover, a first heat-generating device, a first fan, a second heat-generating device and a second fan. The rear cover and the front housing-base are combined to separately form a first heat-dissipation space and a second heat-dissipation space. The rear cover includes a first air-inlet, a second air-inlet and an air-outlet. The first air-inlet and the second air-inlet are in communication with the air-outlet through the first heat-dissipation space and the second heat-dissipation space, respectively. The first fan generates a first airflow, which enters through the first air-inlet, flows through the first heating-generating device accommodated in the first heat-dissipation space, and flows out through the air-outlet. The second fan generates a second airflow, which enters through the second air-inlet, flows through the second heat-generating device accommodated in the second heat-dissipation space, and flows out through the air-outlet.
