technical field

The utility model relates to a solar water heater, which belongs to the mechanical field.

Background technique

At present, the solar water heaters on the market are generally integrated solar water heaters, including a water tank usually installed on the roof. The vacuum glass tube is directly inserted into the water tank, and the convection of the water in the vacuum glass tube is in parallel. The natural convection between the heated hot water and the cold water in the water tank realizes the circulation of hot water and cold water, so that the water temperature in the water tank rises. Since the convection between hot water and cold water is natural convection, the convection speed is relatively slow. The heating effect is relatively poor. The Chinese patent No. 200620088020.X discloses a solar water heater. Its vacuum heat collection tube is composed of more than two large-diameter pressure-bearing vacuum heat collection tubes arranged in parallel from top to bottom. A cold water inlet pipe is inserted into the To the bottom of the vacuum heat collecting tube at the lower end, a hot water outlet pipe is inserted into the upper part of the vacuum heat collecting tube at the upper end. The bottom of a vacuum heat collecting tube is finally introduced into the upper part of the vacuum heat collecting tube at the upper end. Since there is no water storage tank, in order to meet the requirements of use, it is necessary to increase the number of vacuum heat collecting tubes or increase the diameter of the tube, resulting in an increase in volume, and Since there is no water storage tank, it is difficult to achieve the desired heating effect in rainy weather.
