Flat plate integrated solar water heater

Abstract

The invention discloses a flat plate integrated solar water heater which comprises a water tank, a support, a flat plate type solar heat collector fixed to the support, a water inlet pipeline and a water outlet pipeline and further comprises a copper heat pipe, a blind pipe is welded to the lower portion of an inner container of the water tank and extends into the inner container, and the copper heat pipe is welded to the lower portion of the inner container. The flat plate type solar heat collector comprises a shell, a glass cover plate, a heat absorbing body and a heat insulating body arranged between the heat absorbing body and the shell, the heat absorbing body comprises an upper collecting pipe, a lower collecting pipe, a row pipe and a heat absorbing plate, a plurality of sleeves which vertically penetrate through the upper collecting pipe and correspond to the blind pipes are arranged on a pipe section of the upper collecting pipe, evaporation sections of the copper heat pipes are inserted into the sleeves, and the heat insulating body is arranged between the heat absorbing body and the heat absorbing plate. The flat plate integrated solar water heater has the advantages that the flat plate integrated solar water heater is compact in structure, resistant to freezing and impact, comfortable in bathing and good in application prospect.

Description

technical field [0001] The invention relates to the field of solar heat utilization, in particular to a closed solar water heater. Background technique [0002] In existing residential buildings, most of the solar water heaters installed on the roof are vacuum tube type compact solar water heaters, which have the characteristics of not occupying indoor space and excellent thermal performance, but the water outlet pressure depends on the floor drop. Inside, a booster pump needs to be installed to prevent the water outlet pressure from being too low. When the vacuum tube is accidentally damaged, the water heater cannot be used. It is necessary to close the valves of the water supply pipeline and the sewage pipeline for maintenance. Flat-plate solar collectors are more and more used in split-type solar water heating systems on balconies of high-rise buildings. They have the characteristics of impact resistance, beautiful appearance, and easy building integration. The balcony s...
