Indirect solar water heating system

Abstract

The invention discloses an indirect type solar water heating system 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 closed inner container is arranged in a shell of the water tank, and a row of upper inserting holes are formed in the upper portion of the inner container. The lower portion of the inner container is provided with a row of lower inserting holes coaxial with the upper inserting holes, the flat plate type solar heat collector comprises a shell, a glass cover plate, a heat absorption body and a heat insulation body arranged between the heat absorption body and the shell, and the heat absorption body comprises an upper collecting pipe, a lower collecting pipe, a calandria and a heat absorption plate. The upper collecting pipe is provided with a plurality of sleeves which vertically penetrate through the upper collecting pipe and correspond to the lower inserting holes, the evaporation sections of the copper heat pipes are inserted into the sleeves, the condensation sections of the copper heat pipes penetrate through the lower inserting holes and the upper inserting holes and extend out of the inner container, and the indirect type solar water heating system 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 direct 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. Indoors, 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 split ...

AI Technical Summary

Problems solved by technology

The balcony split solar water heating system has the characteristics of high water outlet pressure and frost resistance, but the system is a split structure, the water tank occupies indoor space, the pipeline connecting the water tank and the collector is long, and the balcony wall needs to be embedded with steel sleeves , the installation inclination angle of the collector is limited, the heat gain of the system is low, and the thermal performance is poor
