A photovoltaic inverter, comprising: a casing (10, 11, 12, 13), a first ventilation structure (101, 112) being provided on the casing; a circuit board (30), the circuit board being arranged within the casing; heat dissipation cover plates (20, 21, 22), the heat dissipation cover plates being an aluminium-type material, and being fixedly installed within the casing and arranged above the circuit board. A second ventilation structure (202, 212, 221) relative to the first ventilation structure is provided on the heat dissipation cover plates so that air convection occurs between the first ventilation structure and the second ventilation structure. The photovoltaic inverter uses the aluminium-type material heat dissipation cover plates as a heat sink, and has the advantages of a long service life, low power consumption, zero noise and low costs. |
