Abstract

The invention provides a solar heat collector which comprises two tube plate structures. A certain included angle is formed between the two tube plate structures. The direction of the included angle is opposite to the bending direction of an arc structure of a reflector. The focal point of the reflector is located within the included angle formed by the tube plate structures. Inner fins are arranged in heat collecting tubes and connected with opposite corners of a rectangle. The interiors of the heat collecting tubes are divided into a plurality of small channels through the inner fins. Communicating holes are formed in the inner fins. The outer surfaces of the heat colleting tubes and the outer surfaces of heat collecting plates are coated with anti-corrosion layers. The surface of the heat collector is coated with a corrosion-resisting material, so that the corrosion resistance of the heat collecting tubes is increased, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Solar thermal conversion is a solar energy utilization method with high energy conversion efficiency and utilization rate and low cost, which can be widely promoted in the whole society. In solar heat utilization devices, the key is to convert solar radiation energy into heat energy, and the device that realizes this conversion is called a solar collector. Howeve...
