solar water heaters

Abstract

The invention relates to a novel solar water heater. The novel solar water heater comprises a support, a water storage tank, transparent tubes, evaporation tubes and light gathering plates. The transparent tubes are installed on the water storage tank at equal intervals and are internally vacuumized. The end faces of the light gathering plates are parabolic. A liquid collecting tube is installed on the axis of each transparent tube. The evaporation tubes and the light gathering plates are circumferentially and evenly distributed around the liquid collecting tubes in pairs. The evaporation tubes are parallel to the liquid collecting tubes, and the focus of each light gathering plate is located on the axis of the evaporation tube paired with the light gathering plate. The evaporation tubes in each transparent tube communicate with the liquid collecting tube in the transparent tube, so that a closed circular loop is formed. The upper ends of the evaporation tubes and the liquid collecting tube extend into the water storage tank. The liquid collecting tubes are filled with cooling liquid. The water heater is ingenious in structure, low in cost and capable of supplying hot water efficiently, stably and safely.

Description

technical field [0001] The invention relates to a water heater, especially a solar water heater. Background technique [0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air source water heaters; among them, solar water heaters are favored by the majority of users for their advantages of environmental protection, energy saving, and convenience; The heat rate is relatively slow; two, because the heat collecting tubes are connected to each other, when a crack appears in one of them, the whole water heater will leak, which is not safe and stable; Ice and liquid water become larger after freezing, and it is easy to burst the heat collecting tube; for this reason, people have improved solar water heaters, and a separate vac...

[0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air source water heaters; among them, solar water heaters are favored by the majority of users for their advantages of environmental protection, energy saving, and convenience; The heat rate is relatively slow; two, because the heat collecting tubes are connected to each other, when a crack appears in one of them, the whole water heater will leak, which is not safe and stable; Ice and liquid water become larger after freezing, and it is easy to burst the heat collecting tube; for this reason, people have improved solar water heaters, and a separate vacuum tube water heater can effectively solve the above problems, but this kind of water heater is expensive and the production process is very expensive. Complicated, so generalization is not easy
