Description

Technical Field

[0001] The utility model relates to the technical field of new energy photovoltaics, in particular to a new energy photovoltaic heat dissipation and dust removal structure. Background Art

[0002] Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy. It is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology.

[0003] In the prior art, photovoltaics, as a new energy source, can effectively convert solar energy into electrical energy to achieve energy conservation and environmental protection. There are large photovoltaic bases in many places. In these photovoltaic bases, a large number of solar photovoltaic panels are used to absorb solar energy, and photovoltaic inverters are used to convert solar energy into electrical energy. However, when the photovoltaic inverter converts solar energy, it is very easy to operate at high load when encountering weather or seasons with sufficient solar energy, which will cause the inverter to overheat. If the heat is not dissipated in time, the inverter will be at risk of burning out. When the heat dissipation structure is used to dissipate heat for the inverter, since the solar photovoltaic panels are installed in open places, there is a lot of dust in the air. If the dust net of the heat dissipation structure is not cleaned in time, the heat dissipation effect will be affected, and the inverter will also be at risk of burning out. Therefore, we propose a new energy photovoltaic heat dissipation and dust removal structure. Utility Model Content
