Self-cleaning solar heat collection tube

Abstract

The invention discloses a self-cleaning solar heat collection tube. The tube comprises a left support plate and a right support plate which are arranged in parallel, wherein the left support plate andthe right support plate are of round structures, and a heat collection tube body is arranged on the side walls, close to each other, of the left support plate and the right support plate. The tube has the advantages that a heat absorption plate is used for absorbing solar energy and converts the solar energy into heat, a heat conduction rod and a heat conduction plate are used for conducting theheat to low-boiling-point evaporation liquid, the evaporation liquid reaches the boiling point and is evaporated and vaporized, an arc-shaped sliding plug and an inner magnet are pushed to do circularmotion around the heat collection tube, an outer magnet is attracted to drive a movable plate to move synchronously, a cleaning scraping brush is driven to scrape dust adhered to the surface of the heat collection tube, dust is gradually collected and forms block dirt and falls down, so that the surface of the heat collection tube is cleaned; and when the temperature is lowered, the low-boiling-point evaporation liquid is liquefied to enable the cleaning scraping brush to reversely rotate to perform cleaning again, so that the cleanliness of the surface of the heat collection tube is guaranteed, and the solar energy conversion efficiency of the heat collection tube is improved.

Description

Technical field [0001] The invention relates to the technical field of solar energy, in particular to a self-cleaning solar heat collection tube. Background technique [0002] The solar collector tube is the core element of the solar water heater. The surface of the inner glass tube is coated with a spectral selective absorption coating using a special process to maximize the absorption of solar radiation energy. However, during the long-term use of solar energy, the surface of the solar collector tube is more likely to adhere to dust, and 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] To solve the above problems, we have proposed a self-cleaning solar collector tube. Summary of the invention [0004] The purpose of the present invention is to solve the problems in the background art and propose a self-cleaning solar heat collection tube. [0005] In order to a...
