Embodiment 1

[0021] Such as Figure 1-3 As shown, a solar water heater with the self-cleaning function of the heat collecting tube includes a water storage tank 1 and a plurality of heat collecting tubes 2 fixedly connected with the water storage tank 1, and a plurality of descaling plates 3 are arranged in the heat collecting tube 2 to remove Dirt plates 3 are arranged in a hollow ring shape, and a plurality of descaling plates 3 are arranged perpendicular to the axial direction of the heat collecting tube 2. Each descaling plate 3 is made of a ferrite magnetic material, and its Curie point temperature is 85° C., and two adjacent descaling plates 3 repel each other with the same pole.

[0022] The lower end opening of the heat collecting tube 2 is arranged and sealed and rotatably connected with a tubular scale collecting box 4, and the scale collecting box 4 is fixedly sleeved with two sealing rings 9, and the outer ring side wall of the sealing ring 9 is sealed and rotatably connected w...

Embodiment 2

[0026] Such as Figure 4-5 As shown, the difference between this embodiment and Embodiment 1 is that: the descaling plate 3 is provided with a plurality of oblique water inlet holes 10, and the angle between the water inlet holes 10 and the central axis of the descaling plate 3 is an acute angle. A plurality of water inlet holes 10 are arranged in an annular array in the descaling plate 3 .

[0027] In this embodiment, when the temperature of the water body in the heat collecting tube 2 is high, the magnetism of the descaling plate 3 disappears and sinks downward, and the water in the heat collecting tube 2 flows through the inclined water inlet 10, which can push the descaling plate 3 to rotate , the scale on the inner wall of the heat collecting tube 2 can be scraped and washed horizontally, which further enhances its descaling effect.

Abstract

The invention belongs to the field of new energy, and particularly relates to a solar water heater with a heat collecting pipe self-descaling function. The solar water heater comprises a water storagetank and a plurality of heat collecting pipes fixedly communicating with the water storage tank, wherein a plurality of descaling plates are arranged in the heat collecting pipes and are arranged perpendicular to the axial directions of the heat collecting pipes, the side walls of outer rings of the descaling plates abut against the inner side walls of the heat collecting pipes and slide, the plurality of descaling plates are all made of ferrite magnetic materials, and the same poles of every two adjacent descaling plates repel each other; and openings in the lower ends of the heat collectingpipes are provided with and rotationally connected with a tubular water scale collecting box in a sealed mode, a scale collecting hole is formed in the side wall of the water scale collecting box, the water scale collecting box communicates with the heat collecting pipes through the scale collecting hole, and a threaded column is fixedly connected to the side wall of the water scale collecting box. According to the solar water heater with the heat collecting pipe self-descaling function, the plurality of descaling plates can be driven to slide on the inner walls of the heat collecting pipes through the temperature change of water bodies in the heat collecting pipes, so that water scale is scraped away, and the influence of the water scale on the heat exchange effect of the heat collectingpipes is avoided.

Description

technical field [0001] The invention belongs to the field of new energy sources, and in particular relates to a solar water heater with the self-cleaning function of heat collecting tubes. Background technique [0002] In the era of increasing scarcity of non-renewable energy sources, new clean and renewable energy sources such as solar energy are increasingly attracting people's attention. Among them, solar water heaters are heating devices that convert solar energy into heat energy, and heat water from low temperature to high temperature to meet people's needs in the environment. Hot water use in life and production. [0003] When the existing solar water heater is in use, during the heating process of the water in the heat collecting tube, due to the existence of calcium and magnesium ions in the water, scale will inevitably be generated, and it will adhere to the inner wall of the heat collecting tube, which not only causes the inner diameter of the heat collecting tube ...
