Description

Technical Field

[0001] This utility model relates to the field of phase change energy storage technology, specifically an expanded water tank for phase change energy storage. Background Technology

[0002] Phase change energy storage utilizes the latent heat absorbed or released by materials during phase change processes to store and release energy. Phase change energy storage materials absorb or release a large amount of heat during phase change, which is not characterized by temperature and is therefore called latent heat. The working principle of a phase change water tank is to achieve the storage and release of thermal energy through the properties of phase change materials. When water changes from a liquid to a solid state, it releases latent heat; conversely, when water changes from a solid to a liquid state, it absorbs the same amount of latent heat. Utilizing this property, a phase change water tank can switch between solid and liquid states to achieve the storage and release of thermal energy.

[0003] Chinese utility model patent document CN204730463U discloses a phase change energy storage capacity expansion water tank. The tank has an inner shell inside an insulation material layer, filled with water. The phase change energy storage unit is not submerged in the water. It is supported by a support frame, placed horizontally on a uniformly distributed plate, and positioned at the bottom of the tank. In this design, the phase change material is housed within a sealed outer shell, lacking a mechanism for rapid replacement. This causes inconvenience for subsequent replacement and cleaning of the phase change material. Furthermore, the lack of a water flow control mechanism prevents water from adequately passing through the phase change material for heating, resulting in poor temperature conduction. Utility Model Content

[0004] The purpose of this invention is to provide an expanded water tank for phase change energy storage, which allows for convenient and quick replacement and cleaning of phase change materials and enables sufficient heat conduction of the phase change materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The phase change energy storage expansion tank includes a tank body, with an inlet pipe and an outlet pipe connected to the top and bottom of the tank body, respectively; a phase change material body is installed inside the tank body; a through hole is opened on the side wall of the tank body, and a fixing groove is opened on the outside of the through hole; a detachable mounting base is installed in the through hole; the mounting base is fixedly connected to the phase change material body; a fixing mechanism is also provided between the mounting base and the tank body; the fixing mechanism is located in the fixing groove on the outside of the through hole; the fixing mechanism includes a limiting tooth block, a spring, a push plate, and a guide slider; an annular tooth groove is opened on the outer surface of the mounting base, and a limiting tooth block is movably embedded in the annular tooth groove; a spring is connected between the limiting tooth block and the inner wall of the tank body; a guide slider that slides back and forth along both sides of the fixing groove is also connected to the outer surface of the limiting tooth block; diversion plates are fixedly connected to the inner walls of both sides of the tank body, and three or more diversion plates are arranged in a zigzag pattern and inclined from top to bottom.

[0007] In the aforementioned phase change energy storage expansion tank, a filter screen and a transmission rod are installed inside the water inlet pipe; the transmission rod vertically penetrates the filter screen; a cleaning brush is connected to the upper surface of the filter screen, and turbine blades are installed at the bottom of the filter screen; the cleaning brush and turbine blades are fixedly connected by the transmission rod.

[0008] In the aforementioned phase change energy storage expansion tank, a sealing ring is also embedded on the surface of the mounting base.

[0009] In the aforementioned phase change energy storage expansion tank, a heating unit is embedded and connected to the inner wall of the tank.

[0010] In the aforementioned expanded water tank for phase change energy storage, a thermometer is installed through the inner wall of the tank.

[0011] In the aforementioned phase change energy storage expansion tank, a push plate is also fixedly connected to the outer surface of the guide slider, and the push plate extends out of the fixing groove.

[0012] In the aforementioned phase change energy storage expansion tank, three or more mounting bases are installed on the tank body, and the phase change material body is arranged in an array inside the tank body.

[0013] The beneficial effects of this utility model are:

[0014] (1) By pulling the push plate, the limiting tooth block is separated from the annular tooth groove. Without the limitation of the limiting tooth block, the mounting base can be pulled out of the box to complete the disassembly. During assembly, the mounting base containing the phase change material body is directly inserted into the mounting groove. Under the action of the spring, the limiting tooth block is pushed into the annular tooth groove to limit and fix it, thus completing the assembly. This provides convenience for the replacement and cleaning of the phase change material body of the device.

[0015] (2) When heat release is required, cold water is introduced into the tank through the water inlet pipe. The cold water comes into contact with the phase change material body to exchange heat and thus become hot. During this period, under the guidance of the inclined diversion plate, the water flow can fully contact and be heated with the phase change material body, thereby improving its temperature conduction effect and efficiency.

[0016] (3) Under the filtration effect of the filter screen, scale and impurities in the water can be filtered out to prevent them from entering the tank and causing pollution. At the same time, the water flow can make the turbine blades rotate when passing through the turbine blades. The rotation of the turbine blades drives the cleaning brush to rotate synchronously through the transmission rod. The rotation of the cleaning brush drives the bristles to sweep the mesh of the filter screen, preventing the mesh from being blocked due to the long-term accumulation of scale and impurities, thus ensuring the smooth flow of water.

A phase change material body 5 extending into the tank body 1 is provided on the back of the installation seat 4. A heating unit 6 is embedded in the inner wall of the left side of the tank body 1.

[0027] The assembly and fixing mechanism includes two fixing grooves respectively opened on the inner walls of the mounting groove. The fixing grooves are provided with limiting teeth 7. The surface of the mounting base 4 is provided with annular tooth grooves 8 that are adapted to the limiting teeth 7. The side of the limiting teeth 7 away from the mounting base 4 is provided with a receiving groove. The inner wall of the receiving groove is fixedly connected with a spring 9. The end of the spring 9 away from the inner wall of the receiving groove is fixedly connected to the inner wall of the fixing groove.

[0028] Reference Figure 6 In a preferred embodiment, the front of the housing 1 has a sliding slot extending into the fixed groove. A push plate 10, which is fixedly connected to the front of the limiting tooth block 7, is slidably connected to the inner wall of the sliding slot. Guide sliders 11 are provided on both the upper and lower surfaces of the limiting tooth block 7. Guide grooves for the guide sliders 11 to slide are provided on both the inner top and bottom walls of the fixed groove. Under the guidance of the guide sliders 11, the limiting tooth block 7 can move smoothly within the fixed groove.

[0029] Reference Figure 5 and Figure 7 In a preferred embodiment, a sealing ring 12 is embedded in the surface of the mounting base 4 that overlaps with the mounting groove. The sealing ring 12 improves the sealing performance of the mounting base 4 after assembly with the mounting groove.

[0030] Reference Figure 2 In a preferred embodiment, staggered inclined diversion plates 13 are fixedly connected to the inner walls of both sides of the housing 1. By setting the inclined diversion plates 13, the water flow in the housing 1 can be diverted, so that the water flow can have more contact with the phase change material body 5 for heating.

[0031] Reference Figure 2 and Figure 3 In a preferred embodiment, a thermometer 14 is provided on the upper surface of the tank 1, and a filter screen 15 is provided inside the water inlet pipe 2. The thermometer 14 allows for monitoring of the temperature inside the tank 1, and the filter screen 15 filters the water entering the tank 1.

[0033] The working principle of this utility model is as follows: During use, water is poured into the tank 1 through the inlet pipe 2. The heating unit 6 heats the water and the phase change material body 5 inside the tank 1. When heat release is required, cold water is introduced into the tank 1 through the inlet pipe 2. The cold water contacts the phase change material body 5 for heat exchange, thus becoming hot. During this process, the inclined guide plate 13 ensures that the water flow can fully contact and be heated by the phase change material body 5. During water supply, the filter screen 15 filters out scale and impurities in the water, preventing them from entering the tank 1 and causing pollution. Simultaneously, the water flow rotates the turbine blades 18 as they pass through the turbine blades 18. The rotation of the turbine blades 18 drives the cleaning brush 1 through the transmission rod 16. 7. The cleaning brush 17 rotates synchronously, and the brush bristles sweep the mesh of the filter screen 15 to prevent the mesh from becoming clogged due to the long-term accumulation of scale and impurities. When it is necessary to disassemble and replace the phase change material body 5, pull the push plate 10 to drive the limiting tooth block 7 to retract into the fixing groove, so that the limiting tooth block 7 is separated from the annular tooth groove 8 of the mounting base 4. Without the restriction of the limiting tooth block 7, the mounting base 4 can be pulled out of the box 1 to complete the disassembly. During assembly, the mounting base 4 containing the phase change material body 5 is directly inserted into the mounting groove. During this process, the limiting tooth block 7 is pushed into the annular tooth groove 8 by the action of the spring 9 to limit and fix it, thus completing the assembly.
