Photovoltaic panel cluster cooling system

Abstract

The invention discloses a photovoltaic panel cluster cooling system. A solar photovoltaic panel assembly comprises a cooling air channel plate, a solar photovoltaic panel body, cooling fins and cold air transition connecting pipes; the cooling air channel plate is buckled on the back surface of the solar photovoltaic panel body; the radiating fins are positioned between the cooling air channel plate and the solar photovoltaic panel bod; heat exchange channels are formed among the adjacent radiating fins, the cooling air channel plate and the solar photovoltaic panel body; each heat exchange channel is communicated with one end of the corresponding cold air transition connecting pipe; the other end of each cold air transition connecting pipe in the solar photovoltaic panel assembly is communicated with a corresponding second communicating pipe; the second communicating pipes in heat exchange module are connected with first communicating pipes; the first communicating pipes are connectedwith the bottom of a chimney; and the chimney is vertically distributed. The system has the advantages of being free of water resource consumption, good in economical efficiency and high in heat exchange efficiency.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic power generation, and relates to a photovoltaic panel cluster cooling system. Background technique [0002] With the increasing global warming and energy shortage, solar energy has attracted more and more attention as a clean secondary energy. Solar energy is widely distributed and inexhaustible. After years of development, solar photovoltaic power generation has become increasingly mature. Many solar photovoltaic power stations have been established. The cost of power generation has dropped rapidly, and it has become commercialized. It can be said that photovoltaic power generation It is a major component of future solar power generation and even the development of new energy power generation. [0003] However, the efficiency of photovoltaic power generation has been limited. One of the important reasons is that the performance of photovoltaic panels is inversely proportional to the t...

Problems solved by technology

This also greatly wastes high-quality solar energy resources.

[0004] Therefore, photovoltaic power generation needs to be considered as photovoltaic panel cooling, but due to the large area of ​​photovoltaic panels and low energy density, it is difficult to balance the cooling effect and cost of the cooling system

At the same time, the traditional air-cooled and water-cooled systems need to consume a certain amount of electricity, which is even more unfavorable for photovoltaic power generation systems with low efficiency and scattered areas.

At present, some scholars are studying the PV / T system, that is, the combined application system of photovoltaic power generation and waste heat. The system collects the waste heat generated by photovoltaic panels to provide hot water or other low-temperature heat. However, the power and heat of the photovoltaic system do not match. In terms of the electricity generated by the photovoltaic panels themselves, the amount of hot water provided is too large, and ordinary residents or shopping malls have nowhere to consume so much low-temperature heat

Looking further, in sparsely populated solar power stations are even less efficient for this heat
