Solar collector heat pipe solar vacuum solar

 Heat pipe vacuum tube solar collector consists of part of the heat pipe vacuum tube, union pipe, insulation boxes and brackets and other components. Selective sunlight through the vacuum tube, irradiated in a vacuum tube heat absorption fins on the coating, high absorption rate of solar selective absorbing film solar radiation into heat energy transmitted through the built-in thermal copper heat pipe, quickly a few working fluid vaporization heat pipe evaporation end within vaporized working fluid rises to the heat pipe condensation end, the condensed end rapid heating, thermal block (or thermal sleeve) collectors union pipe absorb the condensation end heat heating union tube fluid. After the heat pipe working fluid release latent heat of vaporization, condensed into a liquid, gravity reflux heat pipe evaporator end, regasification and then condensed. Heat pipe vacuum tube collector heat pipe through a small amount of working fluid vapor - liquid phase change cycle, continuous absorption of solar radiation to provide heat for the hot water system or heating system. Solar collector heat pipe solar characteristics of solar vacuum superconducting heat pipe solar collectors, solar vacuum solar thermal efficiency 1. High-performance selective absorbing coating and high thermal conductivity of the heat transfer bands have heat, heat loss, Under the same conditions set much higher than other forms of heat collectors; 2. pressure to run rated bearing capacity 6kgf / cm2, is particularly suitable for large-scale forced circulation collectors; 3. winter water does not go inside the water hotter pipe rapid start, run throughout the year, and all-glass vacuum tube as compared to 20-30% too much hot water; 4. But summer heat without reflectors, to prevent the ultra-high temperature in summer, the wind load is small, not because of performance degradation reflectors affect the efficiency of the collector; 5. small footprint vacuum closely spaced, small collector dimensions, reducing installation footprint; 6. easy to install copper tube dry plug-in connection maintenance, easy installation, heat pipe condensation end furring, no leakage problems, local maintenance does not affect system operation, to avoid the inner collector furring affect system operation or a tube is damaged the whole system down phenomenon. 7. Long life high efficiency and long life of the heat pipe, strictly control the production process, the normal life of more than 15 years.
