Abstract: A heat dissipation apparatus and a photovoltaic inverter are related to the field of heat dissipation device technologies, to improve a heat dissipation capability of the heat dissipation apparatus. The heat dissipation apparatus includes at least two stacked fan layers, and each fan layer includes at least one fan. A heat dissipation channel in a radiator has a first inlet, and the first inlet communicates with each air exhaust vent in at least one fan layer by using an air duct component. Compared with a solution in which fans are arranged along a width direction of the radiator, the at least two fan layers are stacked, which may not be limited by a width of the radiator. More fans can be arranged in a hierarchical stacking manner, and more fans can increase an overall amount of exhausted air, thereby improving the heat dissipation capability of the heat dissipation apparatus.

Abstract: A power converter, heat exchangers, heat sinks, and a photovoltaic power generation system, related to the field of heat dissipation. The power converter includes: a power semiconductor device, a magnetic element, a sealed cavity, and a heat dissipation cavity. The power semiconductor device and the magnetic element are disposed in the sealed cavity. The power semiconductor device dissipates heat through a first heat sink, and cooling fins of the first heat sink are located in the heat dissipation cavity. The magnetic element dissipates heat through a second heat sink, and cooling fins of the second heat sink are located in the heat dissipation cavity, Accordingly, reliability and heat dissipation effect of heat dissipation performed by the power converter are improved.
