Embodiment 1

[0018] Such as figure 1 As shown, a heat collecting tube for a scale-free solar water heater includes a heat collecting tube 1 fixedly connected with a water storage tank, and a transparent cover tube 2 is provided outside the heat collecting tube 1, and the upper end of the transparent cover tube 2 is fixedly connected with the water storage tank. The transparent cover tube 2 is filled with a mixed gas of nitrogen dioxide and dinitrogen tetroxide, and a reversible reaction can occur between nitrogen dioxide and dinitrogen tetroxide. The inner wall of the transparent cover tube 2 is sealed and slidingly connected with a movable plate 3, transparent The inner wall of the cover tube 2 bottom is fixedly connected with the limit ring 7, which can limit the movable plate 3. The inner wall of the transparent cover tube 2 is provided with a bar-shaped chute 8, and the side wall of the movable plate 3 is fixedly connected with a limit ring 7. The position block 9 and the limit block 9...

Embodiment 2

[0022] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that: the transparent cover tube 2 is rotatably fitted with a sliding sleeve 10, and the outer ring side wall of the sliding sleeve 10 has a plurality of fan blades 11 equidistantly arranged in the circumferential direction. A permanent magnet block 12 is fixedly installed on the side wall of the sliding sleeve 10, a magnet block 13 matching with the permanent magnet block 12 is fixedly connected on the side wall of the rotating shaft 1, and the permanent magnet block 12 and the magnet block 13 are in different polarities. Suck.

[0023] In this embodiment, when the rotating rod 4 rotates, it drives the magnet block 13 to rotate, attracts the permanent magnet block 12 to rotate synchronously under the magnetic force, and then drives the fan blade 11 to rotate through the sliding sleeve 10 to accelerate the air flow on the surface of the transparent cover tube 2, thereby causing The e...

Abstract

The invention belongs to the field of new energy, and particularly relates to a scale-free heat collecting pipe for a solar water heater. The heat collecting pipe comprises a heat collecting pipe bodyfixedly communicating with a water storage tank, wherein a transparent cover pipe is arranged outside the heat collecting pipe body in a sleeving mode, the upper end of the transparent cover pipe isfixedly connected with the water storage tank, mixed gas of nitrogen dioxide and nitrogen tetroxide fills the transparent cover pipe, a movable plate is hermetically and slidably connected on the inner side wall of the transparent cover pipe, a rotating rod is arranged on the central axis of the heat collecting pipe body, one end of the rotating rod sequentially penetrates through the heat collecting pipe body and the movable plate, the rotating rod is rotationally and hermetically connected with the heat collecting pipe body, threads are arranged outside the rotating rod, the rotating rod isin threaded connection with the movable plate, a screw impeller is fixedly connected with the outside of the rotating rod in a sleeving mode, and two scrapers are fixedly connected with the side wallof the screw impeller. According to the heat collecting pipe, the formation of scale can be inhibited by controlling the temperature of a water body in the heat collecting pipe body, and the scale canbe scraped off through the scrapers, so that the influence from the scale on the heat exchange efficiency of the heat collecting pipe is effectively reduced.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a heat collecting tube for a scale-free solar water heater. Background technique [0002] Solar water heater is a heating device that converts sunlight energy into heat energy. It heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. The conversion of solar energy into heat mainly relies on heat collecting tubes, which use hot water to float The principle of cold water sinking makes the water produce microcirculation to obtain the required hot water. [0003] After the existing solar water heater is used for a period of time, a layer of scale will adhere to the inner wall of the heat collecting tube. The scale begins to form at about 70°C, and the formation speed is determined by the content of calcium and magnesium ions in the water. Solar energy As long as the water heater is sunny, the water temperature in th...
