Description

Technical Field

[0002] Photovoltaic inverters can convert the variable DC voltage generated by photovoltaic solar panels into AC power at mains frequency, which can be fed back to commercial power transmission systems or used in off-grid power grids. Photovoltaic inverters are one of the important system balancers in photovoltaic array systems and can be used in conjunction with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding protection.

[0003] During the use of the photovoltaic inverter, the shell needs to protect its internal parts to prevent the internal parts from direct contact with the external environment, which will cause dust and rain to erode the parts and cause parts aging. Existing photovoltaic inverters will absorb dust during use. After long-term use, dust will accumulate on the surface of the internal parts. The dust reduces the heat dissipation efficiency, causing the photovoltaic inverter to overheat and damage the internal parts, thereby reducing the use efficiency of the photovoltaic inverter.

[0004] Therefore, it is necessary to redesign the housing of the photovoltaic inverter to effectively prevent the phenomenon of poor dustproof effect. Utility Model Content

[0026] As a technical optimization scheme of the utility model, by setting a dustproof and heat dissipation mechanism 7, the dustproof ability of the shell 1 can be enhanced, the filter plate 71 can block the dust outside, and the dust removal brush ring 78 can clean and remove dust from the filter plate 71 while the fan 73 rotates. Dust will not enter the interior of the shell, thereby improving the dustproof ability of the shell 1.

[0027] refer to Figure 5 Both sides of the top of the refrigeration plate 75 are fixedly connected with fixing plates 8 , and the outer sides of the fixing plates 8 are fixedly connected to the two sides of the inner wall of the installation shell 6 .

[0028] As a technical optimization solution of the utility model, by setting a fixing plate 8, the cooling plate 75 can be reinforced to prevent the cooling plate 75 from shaking after long-term use, which would cause the connection between the cooling plate 75 and the mounting shell 6 to loosen, thereby improving the use stability of the cooling plate 75.

[0029] refer to Figure 4 Both sides of the front and rear sides of the support frame 74 are fixedly connected with reinforcement plates 9, and the outer side of the reinforcement plate 9 is fixedly connected to the inner wall of the mounting shell 6.

[0030] As a technical optimization solution of the utility model, by setting a reinforcement plate 9, the support frame 74 can be reinforced to prevent the support frame 74 from shaking when the connection on both sides of the support frame 74 is loose, and the inner wall of the support frame 74 collides with the rotating column 72, causing the rotating column 72 to wear, thereby improving the use stability of the support frame 74.

[0036] As a technical optimization solution of the utility model, by providing a reinforcement ring 12, the fan 73 can be reinforced and limited, thereby preventing the connection between the fan 73 and the rotating column 72 from loosening after long-term use, causing the fan 73 to detach from the rotating column 72, thereby improving the use stability of the fan 73.

[0037] The working principle and use process of the utility model are as follows: when in use, the fan 73 is started, and the fan 73 drives the external air to flow into the mounting shell 6, and the filter plate 71 filters the air. The dust in the air is blocked on the outside by the filter plate 71, and the air flows to the expansion tube 77. The expansion tube 77 is designed with a small upper and a large lower opening. According to the working principle of throttling expansion, when the air passes through the expansion tube 77, the volume of the air increases, the pressure decreases, and thus the temperature decreases. The cooled air is transported to the inside of the shell 1 through the ventilation hole 5, and the cold air cools the inside of the shell 1 to achieve the dust-proof effect. The materials used are all lightweight materials, and the rotation of the fan 73 will drive the rotating column 72 to rotate. The rotating column 72 drives the dust removal brush ring 78 to clean the dust attached to the surface of the filter plate 71, and the dust will not be attached to the filter plate 71 for a long time, thereby having the advantage of high efficiency dust prevention.
