Novel environment-friendly solar water heater

Abstract

The invention discloses a novel environment-friendly solar water heater. The novel environment-friendly solar water heater comprises a water tank, solar heat collection tubes, a supporting frame and a base; the novel environment-friendly solar water heater is characterized in that the base is provided with the supporting plate and the solar heat collection tubes, the water tank is arranged on the supporting frame, the water tank is connected with the solar heat collection tubes, a water inlet and a water outlet are formed in the water tank, a heat exchanger is arranged in the water tank, a light reflecting plate is arranged under the solar heat collection tubes, a heat preservation layer is arranged under the light reflecting plate, one end of the light reflecting plate and one end of the heat preservation layer are arranged on the supporting frame, and the other end of the light reflecting plate and the other end of the heat preservation layer are arranged on the base. According to the novel environment-friendly solar water heater disclosed by the invention, clean water can be supplied, environment protection and sanitation are realized, the sunshine utilization rate is high, the heat dissipation of the light reflecting plate can be effectively reduced, and the reflecting efficiency of the light reflecting plate is increased.

Description

technical field [0001] The invention relates to a novel environment-friendly solar water heater. Background technique [0002] At present, a solar water heater is composed of a water tank, a solar heat collecting tube, a support frame and a reflector. The reflector reflects sunlight to the back of the solar heat collecting tube, so that the solar heat collecting tube absorbs more sunlight, but because the reflector itself also dissipates heat, Affects the reflection efficiency of the reflector. And 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 b...

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
