Problems solved by technology

The plate collector is cost-effective, the heat absorption and heat transfer interface is relatively flat, the energy distribution is relatively uniform, there are no hot spots in the entire interface, the overall heat transfer is relatively uniform, and the service life is long. Therefore, the plate collector occupies an important position in the solar thermal field. important position, but the plate collector has poor frost resistance and is not suitable for use in northern regions
The vacuum heat collecting tube can withstand low temperature -30℃, but the damage rate of the glass pipe fittings is high, and the low temperature performance is poor. The vacuum heat collecting tube of the direct current method has the danger of bursting in summer
The efficiency of the heat pipe vacuum collector is better, but there is also the danger of the glass tube being easily broken. Therefore, there is no universal and cost-effective solar collector.

Abstract

The invention discloses a two-dimensional tracking-type focusing solar thermal collector. The two-dimensional tracking-type focusing solar thermal collector comprises a shell, a fluid inflow pipe, a plurality of collecting heater pipes, a fluid discharging pipe, expansion joints, an absorber plate and a shielding plate. The fluid inflow pipe is connected with one end of the shell through one expansion joint, and the fluid discharging pipe is connected with the other end of the shell through the other expansion joint. The collecting heater pipes are connected with one another in parallel. Inlets of the collecting heater pipes all communicate with fluid of the fluid inflow pipe, and outlets of the collecting heater pipes all communicate with fluid of the fluid discharging pipe. The absorber plate is tightly attached to the surfaces of all the collecting heater pipes, and the surface of the absorber plate is coated with a selective absorbing coating. The solar thermal collector is high in heat collecting efficiency, simple and reliable in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a solar photothermal power generation system, in particular to a two-dimensional tracking type focused solar heat collector. Background technique [0002] Energy is the foundation of social development and human progress. With the continuous development of industry and the expansion of human needs, the energy situation is becoming increasingly tense, and green energy is considered to be a way to fundamentally solve human energy needs. [0003] Among them, solar energy is considered to be one of the most potential new energy sources because of its unlimited "reserves", universal distribution, cleanliness and economy. The characteristics of solar thermal power generation are good adaptability to the grid, high photoelectric conversion rate, environmental protection and adjustable, etc., so it has become an important development direction of solar energy utilization. [0004] The key to solar thermal power generation is to accum...
