Solar water heater

Abstract

The invention discloses a solar water heater. The solar water heater comprises a water storage tank, a heat collecting tube, a convex lens cover plate, a supporting base and a reflector plate, wherein a water inlet tube and a water outlet tube are arranged on the water storage tank; and the water storage tank made of metal is arranged inside a balcony. The heat collecting tube is a metal glass vacuum tube; and a panel is formed by jointing convex lenses, so as to quickly increase heat collecting efficiency. The water outlet tube and the water inlet tube which are respectively arranged above and below the heat collecting tube are connected with the water storage tank. The reflector plate, the heat collecting tube and the convex lens cover plate are fixed on the supporting base in sequence, and then, are arranged on the vertical surface of a building. The supporting base and the vertical surface of the building are provided with fasteners which are set to be hangers or bolts convenient to dismount. The solar water heater has the advantages of simple structure, convenience and quickness in use, and capability of improving the quick utilization rate of the solar energy.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater, and belongs to the technical field of solar water heaters. technical background [0002] With the increasing population, the problem of energy shortage is becoming more and more prominent. People consider the development of green energy and solar energy research and utilization. [0003] With the development of solar energy, solar water heaters are more and more cited by the public, but they have many disadvantages: [0004] 1. It is generally installed on the top of the building. Because there is no cover plate, the solar collector plate will be subject to factors such as: hail, lightning strikes and other factors, so there are many safety hazards. Even if the cover plate is installed, the effect of collecting solar heat source will be affected. Moreover, the separate installation method makes it neither beautiful nor conducive to popularization and development; ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is generally installed on the top of the building. Because there is no cover plate, the solar collector plate will be affected by factors such as: hail, lightning strikes and other factors, so there are many safety hazards. Even if the cover plate is installed, it will also affect the effect of collecting solar heat.

Moreover, the separate installation method makes it neither beautiful nor conducive to popularization and development;

[0005] 2. The capacity of the water storage tank is small, and it is only limited to families with a small number of people. Compared with families with more than four people, it is difficult to meet the hot water capacity;

[0006] 3. Buildings with sloped roofs cannot be widely installed;

This product is an improvement over the solar water heater installed on the top of the building, but there are shortcomings in the collection and maintenance of solar energy on cloudy days
