Beschreibung
Zusammenfassung:	The utility model provides an efficient heat dissipation device of a photovoltaic inverter, which comprises a centrifugal fan, an air duct and heat sinks, wherein the air duct is sequentially provided with an air diffusing port, a heat dissipation area and an air outlet, and the air diffusing port is provided with an air inlet end which is communicated with the centrifugal fan, and an air outlet end which is communicated with the heat dissipation area; the heat dissipation area is oppositely matched with a power device of the photovoltaic inverter, and the heat sinks are fixedly arranged in the heat dissipation area and are matched with the power device in a contact way; the heat dissipation area and the power device are oppositely arranged, and the heat sinks are directly contacted with the power device capable of generating high energy; the energy of the power device is transferred to the heat sinks, and air from the centrifugal fan flows through the air diffusing port and then reaches the heat dissipation
