Heat collecting module, heat collecting device and tower type solar power generation system

Abstract

The invention relates to the technical field of solar energy utilization, in particular to a heat collecting module, a heat collecting device and a tower type solar power generation system. The heat collecting module comprises a sealing box body, the sealing box body comprises an endothermic plate located on the front side of the sealing box body, an upper end plate vertically connected to the upper end of the endothermic plate and a lower end plate vertically connected to the lower end of the endothermic plate. The upper end plate and the lower end plate are arranged symmetrically with respect to the endothermic plate, the upper end plate and the lower end plate are provided with heat collecting grooves and similar annular-shaped sealing grooves, the heat collecting grooves are located onthe inner sides of the sealing grooves, at least one through hole is formed in the bottoms of the heat collecting grooves, and through holes of the upper end plate and through holes of the lower endplate communicate one by one correspondingly. According to the heat collecting module, the heat collecting device and the tower type solar power generation system, the modular processing of the heat collecting module can be improved, the handling and assembling of the heat collecting device and the tower type solar power generation system are simplified, and the costs of the heat collecting deviceand the tower type solar power generation system are reduced.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a heat collection module, a heat collection device and a tower solar power generation system. Background technique [0002] With the rapid increase in energy demand for social development, solar energy, as a clean and renewable energy, has been more and more widely used. There are two forms of solar power generation: photovoltaic power generation and thermal power generation. Solar thermal power generation technology gathers the energy of direct sunlight through a large number of reflectors in a focused manner, heats the sun, generates high-temperature and high-pressure steam, and uses steam to drive a steam turbine to generate electricity. [0003] The tower solar power generation system is one of the most widely used solar thermal power generation technologies. It arranges a large number of heliostats on the ground of the power station to form a heliostat field...

AI Technical Summary

Problems solved by technology

[0004] One of the ways to increase the heat absorption efficiency of the heat collector is to increase the heat collection area of ​​the heat collector, which will lead to an increase in the overall volume of the heat collector, which is not conducive to the processing, transportation and installation of the heat collector
