Waterproof fixing device for high-water-resistance HJT photovoltaic cell

Abstract

The invention relates to a waterproof fixing device for a high-water-resistance HJT photovoltaic cell, and the device comprises a main frame, the middle part of the upper end of the main frame is provided with a photovoltaic cell, the outer surface of the upper end of the main frame is provided with a sealing glass plate, the periphery of the main frame is flush with the periphery of the sealing glass plate, and the periphery of the sealing glass plate is connected with a second sealing frame in a sealing manner. A first sealing frame is installed on the outer surface of the second sealing frame, a heat dissipation plate is installed in the middle of the lower end of the main frame, heat dissipation fans are installed on the two sides, close to the heat dissipation plate, of the lower end face of the main frame, and storage openings used for storing the heat dissipation fans are formed in the two sides, close to the heat dissipation fans, of the lower end face of the main frame. A sealing mechanism used for sealing the storage opening is installed at the storage opening of the main frame, and it is ensured that water is completely isolated. Heat is taken away through the heat conduction plate, the heat dissipation fins and the heat dissipation fan, and temperature control is carried out, so that the service life of the HJT photovoltaic cell is prevented from being shortened due to too high temperature.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a waterproof fixing device for a high-resistance water HJT photovoltaic cell. Background technique [0002] Most of the photovoltaic cells need to be installed with a waterproof fixing device on the outside to fix and protect the photovoltaic panel. When the rainy and snowy weather comes, the photovoltaic cells are protected by the waterproof fixing device to prevent water and air, and protect various electronic components. ,like figure 1 shown. [0003] The patent document with the publication number CN208226964U discloses a waterproof frame for photovoltaic panel installation, including photovoltaic modules. Annular grooves are opened in the horizontal part of the frame at the upper and lower ends of the photovoltaic module, and are located in the annular grooves on the left and right sides of the horizontal part. A bar-shaped groove is set up vertically, and a p...

AI Technical Summary

Problems solved by technology

[0004] Existing waterproof fixing devices often drain water through drainage grooves or outlets, which cannot fully seal the protection of HJT photovoltaic cells, which will easily cause HJT photovoltaic cells to be eroded by water vapor during use and reduce their lifespan. It is impossible to achieve rapid heat dissipation and temperature control for HJT photovoltaic cells, and it is impossible to synchronize water and air insulation and rapid heat dissipation, which further reduces the service life of HJT
