Environment-friendly solar water heater

Abstract

The invention discloses an environment-friendly solar water heater. The environment-friendly solar water heater comprises a water tank, solar heat collecting pipes, a support frame and a base, wherein the base is provided with the support frame and the solar heat collecting pipes, the support frame is provided with the water tank, and the water tank is connected with the solar heat collecting pipes; the water tank is provided with a water inlet and a water outlet, a heat exchanger is arranged in the water tank, and the lower parts of the solar heat collecting pipes are provided with a reflecting plate; one end of the reflecting plate is arranged on the support frame, and the other end of the reflecting plate is arranged on the base. The environment-friendly solar water heater can supply clean water, and is environment-friendly and sanitary, high in sunshine utilization rate, safe and reliable, and long in service life.

Description

technical field [0001] The invention relates to an environment-friendly solar water heater. Background technique [0002] As people pay more and more attention to environmental protection and energy, solar water heaters have been adopted by more and more families and businesses. Ordinary solar water heaters use cold water to directly enter the water tank, and then enter the solar heat collecting tube from the water tank. Under the irradiation of sunlight, the inner tube of the solar heat collecting tube will absorb the sunlight and convert it into heat energy and transfer it to the water. It can be directly supplied and used through the water tank, but there are several defects in this method: one is that the cold water is mixed with the water in the water tank, and since the solar heat collecting tube is under the water tank, after each use, the water in the solar heat collecting tube generally does not It will be completely exhausted, so that the water supply is not fresh...

Problems solved by technology

Ordinary solar water heaters use cold water to directly enter the water tank, and then enter the solar heat collecting tube from the water tank. Under the irradiation of sunlight, the inner tube of the solar heat collecting tube will absorb the sunlight and convert it into heat energy and transfer it to the water. It can be directly supplied and used through the water tank, but there are several defects in this method: one is that the cold water is mixed with the water in the water tank, and since the solar heat collecting tube is under the water tank, after each use, the water in the solar heat collecting tube generally does not It will be completely exhausted, so that the water supply is not fresh and clean enough; the second is that cold water directly enters the water tank and the solar heat collector tube, causing the solar heat collector tube to be subjected to instantaneous thermal expansion and contraction, which will not only affect the service life of the solar heat collector tube, but in serious cases, It will cause the solar collector tube to burst; the third is Ca in water 2+ , Mg 2+ Due to the increase of water temperature, the plasma will adhere to the solar collector tube and the inner wall of the water tank to form scale, and the deposition of scale will seriously affect the heat absorption effect of the solar collector tube and affect the service life of the solar collector tube

Moreover, due to the needs of assembly of solar water heaters, there will be certain gaps between the solar collector tubes, and these gaps have not been utilized.
