Solid matter self-guiding intermittent exhausting and upper drainage water pipe anti-freezing solar water heater

Abstract

By changing the siphonopore space of a vacuum pipe solar hot water heater water tank and the structures of an obturating ring and a dustproof ring, the invention realizes the close packing of the solar water heater vacuum pipe, improves the heat collecting efficiency of the solar water heater, saves the installation space and lowers the construction cost of the vacuum pipe solar water heater. Theinvention solves the problems that a water release pipe on the solar water heater in northern China is frozen and blocked and the water release is lost when a householder living on a lower floor of atall building of apartment by adopting a novel water release pipe draining system. By adopting a cold-hot water fluid director inside the vacuum pipe, the invention realizes that naturally circulating ascending water is separated from the descending water inside the vacuum pipe, the hot water is sent to the upper part of a water tank, the cold water is introduced into the lower part of the vacuumpipe, thereby increasing the circulating power, increasing the heat exchange temperature difference between an inner pipe wall of the vacuum pipe and the water and improving the heat absorbing efficiency of the vacuum pipe. The invention reduces the heat dissipation and the vapor and water loss of the atmospheric relief of the solar water heater water tank by adopting the U-shaped pipe upper exhaust steam technique.

Description

Technical field: [0001] The invention relates to related devices and systems for close arrangement of vacuum tube solar water heaters, anti-freezing of upper discharge pipes, natural circulation diversion in vacuum tubes, reduction of steam exhaust loss of solar water heater water tanks, and the like. technical background: [0002] The invention, utility model and appearance design patents of vacuum glass tube solar water heaters disclosed in our country have no fundamental breakthroughs in the close arrangement of vacuum tubes, anti-freezing of upper water pipes, improvement of cold and hot water circulation, and reduction of exhaust loss. Now the most advanced The advanced close-packing technology includes double-layer arrangement, external intubation of the tube seat and reduced diameter of the nozzle. Due to mutual shielding of sunlight, the double-layer arrangement has a complex structure and high cost. Although it is on the market, it has no market. The external intub...

AI Technical Summary

Problems solved by technology

[0003] To sum up, at present, domestic and foreign vacuum tube solar water heaters still have no simple, practical and effective solutions for densely arranged, upper water pipes to prevent freezing, strengthen the water circulation in the tubes, and reduce the heat and soda loss of water tank exhaust, which affects the year of vacuum tube solar water heaters.
