A self-cleaning solar collector tube

Abstract

The invention discloses a self-cleaning solar heat collection tube, which comprises a left support plate and a right support plate arranged in parallel, both of the left support plate and the right support plate adopt a circular structure, and the left support plate and the right support plate are connected to each other. Heat collecting tubes are installed together on the adjacent side walls. The advantages are: the heat-absorbing plate absorbs solar energy and converts it into heat, uses the heat-conducting rod and the heat-conducting plate to transfer the heat to the low-boiling evaporating liquid, reaches the boiling point to evaporate and vaporize, and pushes the arc-shaped sliding plug and the inner magnet to make a circle around the heat-collecting tube At the same time, it attracts the external magnet to drive the movable plate to move synchronously, and then drives the cleaning scraper to scrape off the dust adhered to the surface of the heat collecting tube. The dust gradually gathers and forms a block of dirt and falls down to complete its surface cleaning. When the temperature When it is lowered, the evaporating liquid with low boiling point is liquefied to make the cleaning wiper reversely rotate to clean again, which ensures the cleanliness of the surface of the heat collecting tube and improves the solar energy conversion efficiency of the heat collecting tube.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a self-cleaning solar heat collecting tube. Background technique [0002] The solar collector tube is the core component of the solar water heater. The surface of the inner glass tube is coated with a spectrally selective absorption coating using a special process to absorb solar radiation energy to the maximum. However, during the long-term use of solar energy, the surface of the solar collector tube is more likely to adhere to dust, or even form massive dirt, which prevents the internal coating from absorbing solar energy and affects the solar energy conversion efficiency of the collector tube. [0003] In order to solve the above problems, we propose a self-cleaning solar collector tube. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose a self-cleaning solar heat collecting tube. ...
