Photovoltaic-inverter heat-dissipation assembly

A photovoltaic-inverter heat-dissipation assembly comprising:

• a front housing-base comprising a rear mounting surface and at least one partition element, wherein the at least one partition element is disposed on the rear mounting surface;
• a rear cover combined with the at least one partition element and the rear mounting surface of the front housing-base to form a first heat-dissipation space, a second heat-dissipation space and a third heat-dissipation space, and comprising a first air-inlet, a second air-inlet and at least one air-outlet, wherein the first heat-dissipation space is separated from the second heat-dissipation space and the third heat-dissipation space, the first air-inlet is in communication with the at least one air-outlet through the first heat-dissipation space, and the second air-inlet is in communication with the at least one air-outlet through the second heat-dissipation space and the third heat-dissipation space;
• a first heat-generating device disposed on the rear mounting surface, and accommodated in the first heat-dissipation space;
• a first fan disposed adjacent to the first air-inlet, located between the first air-inlet and the first heat-generating device, and configured to generate a first airflow, which enters through the first air-inlet, flows through the first heating-generating device, and flows out through the at least one air-outlet;
• a second heat-generating device disposed on the rear mounting surface, and accommodated in the second heat-dissipation space;
• and
• a second fan disposed adjacent to the second air-inlet, located between the second air-inlet and the second heat-generating device, and configured to generate a second airflow, which enters through the second air-inlet, flows through the second heat-generating device, and flows out through the at least one air-outlet.
