Water tank used for solar water heater and solar water heater

Abstract

The invention relates to the technical field of solar water heaters and discloses a water tank used for the solar water heaters. The water tank comprises a water storage tank and a medium water tank,wherein, the water storage tank is provided with a hot water outlet and a cold water inlet; the medium water tank is arranged in the water storage tank. A radiating pipe is also arranged in the waterstorage tank. One end of the radiating pipe is communicated with the medium water tank and a medium inlet is formed at the other end of the radiating pipe. The medium water tank is provided with a medium outlet. In the water tank used for the solar water heaters of such structure, the medium fluid which undergoes heating in a heat collector enters the medium water tank again after passing throughthe radiating pipe. The radiating pipe has larger radiating area, so that the medium fluid can carry out full heat exchange with the water in the water storage tank via the radiating pipe. The heat exchange efficiency is higher and the water in the water storage tank can be heated to a higher temperature. The invention also provides a solar water heater.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar water heater water tank, and also to a solar water heater. Background technique [0002] Along with the raising of people's living standard, the application of water heater in daily life is more and more extensive. [0003] Existing water heaters are divided into gas, coal-fired, oil-fired water heaters, and several major categories such as electric water heaters according to energy sources. What the above-mentioned gas, coal-fired, and oil-fired water heaters consume are all non-renewable energy sources, and also cause environmental pollution; meanwhile, as energy prices continue to rise, the above-mentioned gas, coal-fired, and oil-fired water heaters are expensive to use, bringing users a greater economic burden. Because the electricity consumption is large, the price of electricity also has the trend of continuous growth, and there are no small obstacles...

AI Technical Summary

Problems solved by technology

[0012] But in the heat conduction solar water heater of this structure, the medium water tank 103 is used as the heat exchange device for heat exchange between the medium fluid and water, and its heat dissipation area is small, so it cannot fully contact with the water in the water storage tank 102. The thermal efficiency is low, and the heat exchange effect is poor, so that the water in the water storage tank 102 cannot be heated to a higher temperature, and the heated water cannot even reach the use standard

The thermal conduction solar water heater with this structure has been greatly limited in practicality.
