Description

Technical Field

[0001] The utility model relates to a solar heat collection device for a heat pipe medium, in particular to a solar heat collection device for a heat pipe medium applied in the field of solar heat collection pipes. Background Art

[0002] A solar collector tube is a device used to collect solar heat to heat the fluid medium in the tube. Therefore, the function of the collector tube is to convert sunlight into thermal energy and heat the water through heat transfer. When sunlight shines on the collector tube, the internal heat-absorbing coating converts light energy into thermal energy, which increases the water temperature in the tube. The emergence of solar collector tubes has brought great convenience to people when using hot water.

[0003] In areas with cold winters (extremely cold temperatures below 0°C), solar water heating systems are prone to freezing and cracking of glass tubes, water pipes or valves, resulting in freezing disasters, which in turn brings great inconvenience to people when using solar water heating systems. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that in areas with relatively cold winters (extremely cold temperatures below 0°C), solar water heating systems have the problem of frozen cracked glass tubes, frozen cracked water pipes or valves, resulting in freezing disasters.

[0005] To solve the above problems, the utility model provides a solar energy heat collecting device with a heat pipe medium, comprising a heat collecting tube, wherein a copper heat pipe and an aluminum alloy fin are arranged inside the heat collecting tube, a sealing ring is movably inserted at the side end of the heat collecting tube, an end of the sealing ring away from the heat collecting tube is fixedly connected with the aluminum alloy fin, an end of the copper heat pipe away from the sealing ring passes through the sealing ring and the aluminum alloy fin, and extends out from the aluminum alloy fin, a protective tube is sleeved on the outer end of the heat collecting tube, a retaining ring is arranged at the end of the protective tube close to the sealing ring, and the inner wall of the retaining ring is fixedly connected to the outer end of the heat collecting tube.

[0006] In the above-mentioned solar energy heat collection device with heat pipe medium, it can not only avoid the problem of easy freezing and cracking of glass tubes, but also increase the temperature of hot water, thereby improving the heat exchange efficiency.

[0007] As a further improvement of the present application, a first magnetic ring is fixedly connected to one end of the retaining ring close to the protective tube, and a second magnetic ring is fixedly connected to the inner wall of the protective tube.

[0008] As another improvement of the present application, one end of the protective tube away from the retaining ring is threadedly connected to a threaded ring, and one end of the threaded ring away from the protective tube is fixedly connected to a movable tube. The inside of the movable tube is movably plugged with a connecting ring, and a sponge ring is fixedly connected to the inner wall of the connecting ring.

[0009] As another improved supplement of the present application, the inner wall of the sponge ring is slidably connected to the outer end of the heat collecting tube, and the moving tube sleeve is arranged on the outer end of the heat collecting tube.

[0010] As another improved supplement of the present application, a pair of limit blocks are fixedly connected to the outer end of the plug-in ring, and a pair of limit grooves movably connected to the limit blocks are opened on the inner wall of the moving tube.

[0011] As another improvement supplement of the present application, a magnetic coating 1 is coated on one end of the limiting block away from the plug-in ring, and a magnetic coating 2 is coated on the inner wall of the limiting groove.

[0012] In summary, when using this device, it can avoid the problem of glass tubes being easily frozen and cracked, and the tubes will never freeze. Through the copper heat pipe, the temperature of hot water can be increased, thereby improving the heat exchange efficiency. The use of aluminum alloy fins can not only fix the copper heat pipe, but also enhance the thermal conductivity. The critical phase change temperature of the phase change material in the copper heat pipe is 95°C, which can be customized according to personnel needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method:

[0022] Figure 1-4A solar heat collecting device with a heat pipe medium is shown, comprising a heat collecting tube 1, the heat collecting tube 1 is made of silicon boron, a copper heat pipe 2 and an aluminum alloy fin 4 are arranged inside the heat collecting tube 1, a sealing ring 3 is movably inserted at the side end of the heat collecting tube 1, the end of the sealing ring 3 away from the heat collecting tube 1 is fixedly connected to the aluminum alloy fin 4, the end of the copper heat pipe 2 away from the sealing ring 3 passes through the sealing ring 3 and the aluminum alloy fin 4, and extends out from the aluminum alloy fin 4, a protective tube 5 is sleeved on the outer end of the heat collecting tube 1, a retaining ring 6 is arranged at the end of the protective tube 5 close to the sealing ring 3, the inner wall of the retaining ring 6 is fixedly connected to the outer end of the heat collecting tube 1, a first magnetic ring 7 is fixedly connected to the end of the retaining ring 6 close to the protective tube 5, and a second magnetic ring 8 is fixedly connected to the inner wall of the protective tube 5.

[0023] This solution can be achieved. One end of the aluminum alloy fin 4 extending out is the condensation end of the copper heat pipe 2. When in use, under the irradiation of sunlight, it absorbs light energy and converts it into heat energy, which is then conducted to the aluminum alloy fin 4 and the copper heat pipe 2. The copper heat pipe 2 is filled with a phase change material heat medium (designed phase change critical temperature is 95°C) in a vacuum environment. By using the heat pipe principle, the copper heat pipe 2 quickly transfers heat to its top condensation end, the condensation end heat collection manifold, heats the circulating hot water system, and quickly collects heat in the water storage tank. When in use, the device can avoid the problem of glass tubes being easily frozen and cracked, and the tubes will never freeze. The copper heat pipe 2 can increase the temperature of the hot water, thereby improving the heat exchange efficiency. The aluminum alloy fins 4 can be used to fix the copper heat pipe 2 and enhance the thermal conductivity. The critical phase change temperature of the phase change material in the copper heat pipe 2 is 95°C, which can be customized according to personnel needs and can be set to a temperature of 45-300°C. If a wax phase change material is used, when the collector tube 1 is removed from the solar water heater for maintenance, the protective tube 5 needs to be pushed to allow the condensation end of the copper heat pipe 2 to enter the protective tube 5. At the same time, the first magnetic ring 7 will be adsorbed together with the second magnetic ring 8, thereby improving the stability of the protective tube 5 after movement. The protective tube 5 can be used to protect the condensation end of the copper heat pipe 2 to prevent the condensation end of the copper heat pipe 2 from colliding with foreign objects when the collector tube 1 is moved.

[0024] The second implementation method:

[0025] Based on the first embodiment, this embodiment adds structures such as a threaded ring 9 and a sponge ring 12, and the rest of the parts are consistent with the first embodiment.

[0026] Figure 2 and Figure 5It is shown that the end of the protective tube 5 away from the retaining ring 6 is threadedly connected with a threaded ring 9, and the end of the threaded ring 9 away from the protective tube 5 is fixedly connected with a movable tube 10, and a plug-in ring 11 is movably inserted inside the movable tube 10, and a sponge ring 12 is fixedly connected to the inner wall of the plug-in ring 11, and the inner wall of the sponge ring 12 is slidably connected to the outer end of the heat collecting tube 1, and the movable tube 10 is sleeved on the outer end of the heat collecting tube 1, and a pair of limit blocks 13 are fixedly connected to the outer end of the plug-in ring 11. The limit blocks 13 can prevent the plug-in ring 11 from rotating, and further prevent the sponge ring 12 from rotating on the heat collecting tube 1, and a pair of limit grooves 14 movably plugged with the limit blocks 13 are opened on the inner wall of the movable tube 10, and the end of the limit block 13 away from the plug-in ring 11 is coated with a magnetic coating 15, and the inner wall of the limit groove 14 is coated with a magnetic coating 2 16. When the magnetic coating 15 and the magnetic coating 2 16 are adsorbed together, the stability of the limit block 13 in the limit groove 14 can be improved.

[0027] This solution can be achieved, when the heat collecting tube 1 is removed for maintenance, the movable tube 10 needs to be rotated to remove the threaded ring 9 from the protective tube 5, thereby separating the movable tube 10 from the protective tube 5, and then moving the movable tube 10 to move toward the end away from the protective tube 5. When the movable tube 10 moves, the sponge ring 12 will move closely on the heat collecting tube 1, thereby cleaning the surface of the heat collecting tube 1, removing dust and foreign matter adhering to the surface, and then keeping the surface of the heat collecting tube 1 smooth.

[0028] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted by this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
