Brief Introduction of Solar Heat Pipe-Vacuum Pipe Solar Collector




Heat pipe vacuum tube solar collector is composed of heat pipe vacuum tube, manifold, incubator and bracket. It has the advantages of high thermal efficiency. Heat pipe vacuum tube solar collector consists of heat pipe vacuum tube, manifold, heat preservation box and support. The sunlight passes through the vacuum glass tube and irradiates on the selective absorbing coating of metal endothermic fins in the vacuum tube. High absorptive solar selective absorption film converts solar radiation energy into heat energy, and transfers it to the built-in heat pipe through the heat conducting copper strip. A small amount of working substance evaporates rapidly at the evaporating end of the heat pipe, and the vaporized working substance rises to the condensing end of the heat pipe. The condensing end is heated rapidly, and the collector is connected. The heat conducting block (or heat conducting sleeve) on the collector absorbs heat from the condensation end to heat the fluid in the collector. After releasing the latent heat of evaporation, the heat pipe refrigerant condenses into liquid. Under the action of gravity, the evaporating end of the heat pipe flows back, then evaporates and condenses. The heat pipe vacuum tube collector can continuously absorb solar radiation through the gas-liquid phase transition cycle of a small amount of working substance in the heat pipe, providing heat source for hot water or heating system.
