Combined type high-strength solar heat collecting tube

Abstract

The invention discloses a combined high-strength solar heat collecting tube, which belongs to the technical field of heat exchange parts, and comprises a heat collecting inner tube and a heat collecting outer tube, one end of the heat collecting outer tube is provided with a mounting sleeve, the heat collecting inner tube is arranged in the heat collecting outer tube, and the heat collecting outer tube is externally provided with a light condensing assembly. The heat collection effect of the heat collection outer tube is stably improved; according to the solar heat collection tube, the light condensation assembly capable of automatically expanding is arranged outside, the design is reasonable and ingenious, by designing a temperature control structure, automatic expansion of the light condensation assembly can be effectively achieved, the light condensation area of the light condensation assembly is increased, the heat collection tube can collect stronger sunlight and heat energy, the use effect of the heat collection tube is improved, manual control is not needed, and the production cost is reduced. Due to the fact that the convex lens is adopted in the light condensation assembly, the light condensation effect of the light condensation assembly can be further guaranteed, meanwhile, the expanded light condensation assembly forms a good barrier for the heat collection pipe, the good protection effect is achieved, and the whole heat collection pipe is not prone to being damaged.

Description

technical field [0001] The invention belongs to the technical field of heat exchange parts, and in particular relates to a combined high-strength solar collector tube. Background technique [0002] The collector tube is a heat collection and heat exchange component, which is mainly used in thermal energy collection equipment. The collector tube is installed in the solar water heater. The collector tube is one of the most important and basic structures in solar energy equipment. [0003] Most of the existing heat collecting tubes are not provided with a concentrating structure on the outside, which makes it impossible to effectively gather sunlight, so that the heat collecting effect of the heat collecting tubes cannot be steadily improved. Concentrating structure, but the overall function of the concentrating structure is single, and the area of ​​the condensing area cannot be automatically expanded normally, resulting in the inability to achieve the best light-concentrating...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that most of the existing heat collecting tubes are not equipped with a light concentrating structure on the outside, resulting in the inability to effectively gather sunlight, so that the heat collecting effect of the heat collecting tubes cannot be steadily improved. To solve this problem, a concentrating structure is installed on the outside, but the overall function of the concentrating structure is single, and the area of ​​the concentrating area cannot be expanded automatically, resulting in the inability to achieve the best concentrating performance, and it does not have a stable protection function for the heat collecting tube problem, and proposed a combined high-intensity solar collector tube
