Description

Technical Field

[0001] The utility model relates to the technical field of solar heating, in particular to a partition exchange type solar heater. Background Art

[0002] A solar water heater is a device that uses solar energy to heat water to meet people's hot water needs in life and production. It uses solar collectors to collect and absorb the sun's heat, and then transfers the heat to water to achieve water heating.

[0003] However, in actual life, the water heater is affected by the water quality. During long-term use, scale will adhere to the heat pipe or hot water tank, resulting in a decrease in the heat exchange effect, so that the water in the hot water tank cannot maintain the normal set temperature. Later maintenance work is required to remove the attached scale. During maintenance, the evenly distributed heat pipes need to be disassembled one by one, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to provide a partition exchange type solar heater to overcome the above-mentioned defects in the prior art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] According to the utility model, a partition exchange type solar heater comprises two left-right symmetrical support frames, a hot water tank is arranged between the two support frames, a heat preservation layer is arranged in the hot water tank, water pipes are connected to the left and right ends of the hot water tank, a vacuum tube is connected to the front end of the hot water tank, a support plate is fixed to the front end of the vacuum tube, a heating mechanism is arranged in the vacuum tube, the heating mechanism extends backward into the heat preservation layer, a cleaning mechanism is arranged in the hot water tank, the heating mechanism comprises a heat pipe arranged in the vacuum tube, a heat absorbing plate and a heater distributed front and back are arranged on the outer periphery of the heat pipe, and the upper end portion of the heat pipe A temperature sensor is provided, a small amount of volatile liquid is contained in the heat pipe, the cleaning mechanism includes a fixed baffle fixedly arranged in the hot water tank, a fixed frame evenly distributed front and back is slidably connected to the fixed baffle, a floating plate is fixedly provided on the rear end part of the fixed frame, a counterweight ring is fixedly provided on the front end part of the fixed frame, a hanging ring is provided on the front end part of the counterweight ring, the hanging ring is sleeved on the heat pipe, the outer peripheral part of the heat pipe is in close contact with the heat absorbing plate and the heater, a discharge valve is connected to the lower end of the hot water tank, and the radius of the heat pipe located in the vacuum tube part is smaller than the radius of the heat pipe located in the insulation layer part.

[0007] The beneficial effects of the utility model are:

[0008] By opening the discharge valve, impurities dropped from the heat pipe can be cleaned without the need for staff to disassemble the vacuum tube and heat pipe for cleaning, thereby improving maintenance efficiency.

[0009] The volatile liquid inside the heat pipe absorbs heat to the upper end of the heat pipe, and the upper end of the heat pipe contacts the water in the hot water tank to increase the temperature. By isolating the hot water tank and the vacuum tube, impurities in the water flow through the water and adhere to the vacuum tube. Therefore, there is no need to disassemble the vacuum tube during maintenance, thereby improving maintenance efficiency.

[0010] Placing the temperature sensor and heater at the vacuum tube can effectively prevent the water in the hot water tank from coming into contact with the temperature sensor and heater, thereby preventing scale from forming at the temperature sensor and heater in a long-term working environment, eliminating the impact of scale on the temperature sensor and heater, and extending their service life.

[0011] The hanging ring moves up and down by changing the water level to automatically clean the peripheral part of the heat pipe. BRIEF DESCRIPTION OF THE DRAWINGS

When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:

[0023] Example 1:

[0024] Reference Figure 1-Figure 7 According to an embodiment of the present invention, a partition exchange type solar heater includes two left-right symmetrical support frames 12, a hot water tank 10 is provided between the two support frames 12, an insulation layer 15 is provided in the hot water tank 10, water pipes 11 are connected to the left and right ends of the hot water tank 10, a vacuum tube 14 is connected to the front end of the hot water tank 10, a support plate 13 is fixed to the front end of the vacuum tube 14, a heating mechanism 25 is provided in the vacuum tube 14, the heating mechanism 25 extends backward into the insulation layer 15, a cleaning mechanism 26 is provided in the hot water tank 10, the heating mechanism 25 includes a heat pipe 17 arranged in the vacuum tube 14, and a heat absorbing plate 18 and a heater 19 distributed front and back are provided on the outer periphery of the heat pipe 17. A temperature sensor 16 is provided at the upper end of the tube 17. A small amount of volatile liquid is contained in the heat pipe 17. The cleaning mechanism 26 includes a fixed baffle 20 fixed in the hot water tank 10. The fixed baffle 20 is slidably connected to a fixed frame 23 evenly distributed front and back. A floating plate 22 is fixed to the rear end of the fixed frame 23, and a counterweight ring is fixed to the front end of the fixed frame 23. A hanging ring 24 is provided at the front end of the counterweight ring. The hanging ring 24 is sleeved on the heat pipe 17. The outer peripheral portion of the heat pipe 17 is in close contact with the heat absorbing plate 18 and the heater 19. A discharge valve 21 is connected to the lower end of the hot water tank 10. The radius of the heat pipe 17 located in the vacuum tube 14 is smaller than the radius of the heat pipe 17 located in the insulation layer 15.

[0025] This program has the following working process:

[0026] The hot water tank 10 is connected to the water inlet and the water outlet through the water pipes 11 connected on the left and right. For example, the water pipe 11 at the left end supplies water to the hot water tank 10. The water level in the hot water tank 10 rises, and the water in the hot water tank 10 is heated by the vacuum tube 14 and the heating mechanism 25. The water is then discharged outward through the water pipe 11 at the right end. The water pipe 11 is connected to a water valve to control the water inlet and outlet of the hot water tank 10.

[0027] The hot water tank 10 and the vacuum tube 14 are supported by the support frame 12 and the support plate 13 and are arranged on the installation surface. The vacuum tube 14 is tilted to contact the sunlight. The sunlight passes through the vacuum tube 14 and irradiates the heat absorbing plate 18. The internal coating of the vacuum tube 14 reduces the radiation loss of the sunlight. The heat absorbing plate 18 absorbs the sunlight and converts the solar energy into heat. The heat absorbing plate 18 is attached to the heat pipe 17 to heat the heat pipe 17, so that the temperature of the liquid in the heat pipe 17 is increased, so that the liquid circulates in the heat pipe 17. The hot water rises in the heat pipe 17 and the cold water falls in the heat pipe 17. When the temperature is increased, the liquid evaporates and flows to the upper end of the heat pipe 17. At the hot water tank 10, the upper end of the heat pipe 17 passes through the hot water tank 10 and the thermal insulation layer 15 and is located inside the hot water tank 10 and contacts the water, thereby increasing the temperature of the water in the hot water tank 10.

[0028] During use, the water level in the hot water tank 10 drops, and the floating plate 22 floats on the water surface and moves downward as the water level drops, thereby driving the hanging ring 24 to move downward through the fixing frame 23. The hanging ring 24 fits the upper end of the heat pipe 17 to clean the surface impurities on the upper end of the heat pipe 17. When water is added to the hot water tank 10, the water level in the hot water tank 10 rises, and the floating plate 22 moves upward as the water level rises, thereby driving the hanging ring 24 to move back and forth, and the hanging ring 24 cleans the impurities on the heat pipe 17.

[0029] The impurities cleaned by the hanging ring 24 settle down near the discharge valve 21. When cleaning, the discharge valve 21 is opened to allow the impurities and water to flow downward through the opening at the discharge valve 21 to discharge the impurities.

[0030] The temperature value of the gas moving to the upper end of the heat pipe 17 is detected by the temperature sensor 16 and compared with the set value at the temperature sensor 16. When the detected temperature value is lower than the set stable value of the temperature sensor 16, the temperature sensor 16 is connected to the heater 19 signal, the heater 19 is connected to the power supply, the heater 19 works to heat up, and the temperature in the heat pipe 17 rises.

[0031] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All such modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims appended hereto.
