Problems solved by technology

[0003] In the prior art, a solar heat collector with a tube-sheet structure is given, and because the fins are arranged inside, the pressure increases. In order to reduce the pressure, communication holes are provided on the fins, but the fins and spacing of the communication holes are generally They are all the same, which leads to excessive pressure at the position where the heating is strong, and the communication holes are not enough to relieve the pressure, which leads to the short service life of the collector part due to too much pressure, so it is necessary to overcome this Happening

Abstract

The invention provides a solar heat collector. The solar heat collector comprises two tube plate structures, wherein a given angle is formed between the two tube plate structures, the direction of the angle is opposite to the bending direction of an arc linear structure of a reflector, a focal point of the reflector is disposed between the angles formed by the tube plate structures, inner fins are arranged inside a heat collection pipe, the inner fins are connected with a rectangular opposite angle, the interior of the heat collection pipe is divided by the inner fins into a plurality of small passages, communication holes are formed in the inner fins, and the spacing among the communication holes of different heat collection pipes is gradually reduced along the extension direction from the junction of the two tube plate structures to lowest positions on two sides. By adopting the solar heat collector, the basically identical pressure can be kept inside different heat collection pipes, so that the overall service life of the heat collection pipe is prolonged, the heat exchanging area of the inner fins of the heat collection pipes can be guaranteed, and the heat conduction can be improved.

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...
