Solar Water Heater

Pressurized solar water heater, with full name of phase-change heat conduction full pressure solar water heater, adopts phase-change heat conduction tube which consists of vacuum tube, phase change heat pipe and heat transfer aluminum-wing. Benefiting from vacuum tube’s high solar absorptance and low reflectivity coating, it transfers solar radiation into heat energy. Through heat transfer aluminum-wing, the selective coating passes the energy to phase change heat pipe and the inside heat transfer medium passes the energy to water in pressurized water tanks within two phase transitions, bring the water temperature increase. No water in the vacuum tube and whole system has capability of withstanding pressure. Hot water runs out under water pressure. Solar vacuum possesses distinguishing features of tracking solar energy. The whole system thus works smoothly whenever there is solar radiation. Due to the one-way heat transferring character of phase change heat pipe, the product works the year around, even in rigid cold regions.
