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.
