Abstract

The invention discloses a photovoltaic inverter. The photovoltaic inverter comprises a body and a driving mechanism, a heat dissipation part is arranged on the back of the body, the heat dissipation part comprises a cover body and a pair of heat dissipation plate sets, the cover body is fixed to the body, and heat dissipation holes which are arranged in order are formed in the two sides of the cover body; the heat dissipation plate sets are oppositely arranged on the two sides of the interior of the cover body, each heat dissipation plate set comprises at least one heat dissipation plate, and heat dissipation holes are formed in the heat dissipation plates in order. The heat dissipation plate set is driven by the driving mechanism to enable the heat dissipation plates and the side portion of the cover body to be arranged at intervals or attached to each other. The heat dissipation plate set is driven by the driving mechanism to enable the heat dissipation plates and the heat dissipation holes in the side portion of the cover body to be arranged in a staggered mode or in a concentric mode. The beneficial effects of the invention are that through the heat dissipation holes which are arranged in a staggered manner, dust entering can be reduced or avoided while heat dissipation is carried out; the heat dissipating capacity can be increased through the concentrically arranged heat dissipating holes; the heat dissipation plate is attached to the side portion of the cover body, and the heat dissipation holes are arranged in a staggered mode, so that rainwater can be prevented from entering the cover body.

Description

technical field [0001] The present application relates to the technical field of inverters, and in particular, to a photovoltaic inverter. Background technique [0002] A photovoltaic inverter is an inverter that can convert the variable DC voltage generated by photovoltaic solar panels into AC frequency AC power, which can be fed back to the commercial power transmission system or used for off-grid power grids. [0003] With the gradual method of technology, photovoltaic solar power generation technology is gradually becoming domestic, and the photovoltaic inverter used needs to be installed outdoors. Due to the working characteristics of the photovoltaic inverter, the internal temperature of the photovoltaic inverter is relatively high during operation, and a heat dissipation device and a related heat dissipation structure need to be installed. The common heat dissipation structure can use heat dissipation holes. However, for photovoltaic inverters installed outdoors, the...
