Flexible cooling device of photovoltaic cell

Abstract

The invention relates to a cooling device of a photovoltaic cell, which is particularly suitable for a low-power light condensing photovoltaic cell and belongs to the field of solar energy utilization. An installable and detachable flexible profiled cooling device is installed in a photovoltaic cell frame (2); the flexible profiled cooling device comprises a flexible profiled body (3) which is manufactured in an edge sealing way, a water inlet (4) which is positioned at the bottom of the flexible profiled body (3), a water outlet (5) and a top cover safe hole (6) which is positioned at the top of the flexible profiled body (3); the periphery of a solar cell panel (1) is positioned in a sealing edge (21) on the frame (2); a filler (7) is arranged between the periphery of the solar cell panel (1) and the sealing edge (21); an inner support (8) is positioned in the flexible profiled body (3); and a current divider (9) is arranged in the inner support (8). The device not only meets the heat radiating requirement of the cell panel but also meets the seal requirement of the cell panel, is easy for replacement and is suitable for large-scale industrialized use.

Description

technical field [0001] The invention relates to a cooling device for photovoltaic cells, which is especially suitable for low-magnification focusing photovoltaic cells, and belongs to the technical field of energy utilization. Background technique [0002] As a clean, non-polluting renewable energy, solar energy is considered an important part of the world's energy strategy for its development and utilization. According to statistics, by 2030 new energy will account for more than 30% of the total energy, while solar photovoltaic power generation The proportion in the world's total power supply will also reach more than 10%, so photovoltaic power generation is one of the most promising power generation technologies. Photovoltaic cells mainly convert solar energy directly into electrical energy through the photovoltaic effect. According to different materials, they can be divided into: monocrystalline silicon cells, polycrystalline silicon cells, and thin film cells. The surv...

Problems solved by technology

However, most of the existing cooling schemes can guarantee a good heat dissipation effect, but the time they can maintain watertightness generally does not exceed 10 years, which seriously affects the efficiency and safety of solar cells, and some existing cooling schemes are not compatible with solar cells. Integrate with and therefore difficult to replace, even if replacement is expensive

In addition, since some solar cells are designed to track the sun's trajectory, their positions in space are constantly changing. Whether they can continue to maintain a good heat dissipation effect during continuous rotation is also a difficult point in the design of cooling devices
