Heat pipe vacuum tube solar collector is one of the collectors. It is more efficient than other collectors. It is a new type of collector. Most of the heat pipe vacuum tube solar collectors are made of stainless steel water tanks, which are then fixed and sealed through silica gel rings. Today, Xiaobian will introduce to you the characteristics of heat pipe vacuum tube solar collector.
Brief Introduction of Solar Energy Heat Pipe-Heat Pipe Vacuum Tube Solar Energy Collector
Heat pipe vacuum tube solar collector is composed of heat pipe vacuum tube, manifold, heat preservation box and bracket, which has the advantage of high thermal efficiency. Heat pipe vacuum tube solar collector is composed of heat pipe vacuum tube, manifold, heat preservation box and bracket. Solar light passes through the vacuum glass tube and irradiates on the selective absorbing coating of the metal heat absorbing fins in the vacuum tube. The high absorptivity solar selective absorbing film converts solar radiation energy into heat energy and transmits it to the built-in heat pipe through the heat conducting copper strip. The small amount of working substance in the evaporating end of the heat pipe is vaporized rapidly, and the vaporized working substance rises to the condensing end of the heat pipe, so that the condensing end is heated rapidly and the collector is connected. The heat conducting block (or heat conducting sleeve) on the header absorbs heat from the condensation end to heat the fluid in the header. After releasing the latent heat of vaporization, the heat pipe refrigerant condenses into liquid. Under the action of gravity, the evaporating end of the heat pipe is refluxed, then vaporized and condensed. The heat pipe vacuum tube collector can continuously absorb solar radiation to provide heat source for hot water or heating system through the vapor-liquid phase change cycle process of a small amount of working substance in the heat pipe.
