Description

Technical Field

[0001] The present application relates to the field of photovoltaic energy storage technology, and in particular to a photovoltaic energy storage inverter. Background Art

[0002] Photovoltaic energy storage inverters can convert the variable DC voltage generated by photovoltaic (PV) solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic energy storage inverters are one of the important system balances (BOS) in photovoltaic array systems and can be used with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding effect protection. Photovoltaic energy storage inverters are a type of device that can convert the DC power of solar panels into AC power. When there is sufficient sunlight, it can convert the electrical energy collected by solar panels into the energy required for household, commercial or industrial use.

[0003] A large number of electrical components are installed inside the box of the photovoltaic energy storage inverter. During operation, the electrical components will generate a large amount of heat inside the photovoltaic energy storage inverter, which will damage the electrical components and thus affect the service life of the photovoltaic energy storage inverter. In order to ensure the service life of the photovoltaic energy storage inverter, the existing method generally adopts an external circulation method to cool the inside of the photovoltaic energy storage inverter. Generally, the external air is extracted into the interior of the photovoltaic energy storage inverter by a heat dissipation fan to perform heat exchange to achieve the purpose of cooling the interior of the photovoltaic energy storage inverter. However, when the fan extracts the external air, the dust and impurities in the air will be extracted into the interior of the photovoltaic energy storage inverter. The dust and impurities will also cause damage to the electrical components. Therefore, the existing method is to install a filter on the periphery of the heat dissipation fan to filter the dust and impurities. However, after long-term use, the filter will accumulate dust, which seriously affects the actual working efficiency of the heat dissipation fan, affects the internal heat dissipation of the photovoltaic energy storage inverter, and thus affects the service life of the photovoltaic energy storage inverter.

[0025] Please refer to Figure 1 , the embodiment of the present application provides a novel self-cleaning box for a photovoltaic energy storage inverter, comprising a box 1, a heat dissipation mechanism 2 and a cleaning mechanism 3;

[0026] The box body 1 is configured as a photovoltaic energy storage inverter box body, which is used to provide support and working environment for the overall device; the inner walls of both ends of the box body 1 along the length direction are fixedly provided with mounting frames 11; the mounting frames 11 are configured as square frames; both end surfaces of the box body 1 along the length direction are movably embedded with filter plates 12; the inner four corners of the mounting frame 11 are installed along the length direction of the box body 1; the movable ends of the telescopic rods 13 are fixedly connected to the adjacent filter plates 12;

The water pump 34 pumps the cleaning water in the water storage tank 35 into the main pipeline 33, and then the water is sprayed onto the filter plate 12 through the pipeline 31 by the nozzle 32, so as to flush and clean the filter plate 12. During the flushing and cleaning process, the cooling fan 22 is started.
