Description

Technical Field

[0001] This utility model belongs to the field of solar thermal technology, and in particular relates to a vertical phase change heat storage tank. Background Technology

[0002] In today's global energy landscape, with the deepening development and utilization of renewable energy and the ever-growing demand for energy conservation such as industrial waste heat recovery, efficient thermal energy storage technology has become a key element. Traditional thermal storage methods often face many problems such as low thermal density, large heat loss, and insufficient temperature control.

[0003] In existing phase change thermal storage tank technologies, horizontal thermal storage tank designs are often used. This design takes up a lot of floor space. At the same time, the thermal stratification phenomenon in horizontal thermal storage tanks is relatively weak, which may require special flow guiding devices to enhance the thermal stratification effect and improve heat exchange efficiency. Moreover, it is inconvenient to replace the heat storage plate in existing thermal storage tanks. Therefore, we propose a vertical phase change thermal storage tank. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical phase change heat storage tank, which uses a handle to move a circular plate, thereby moving the heat storage plate upward and detaching it from the overall device, thus solving the problem of inconvenience in replacing the heat storage plate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vertical phase change thermal storage tank, comprising a thermal storage mechanism and a fixing frame. The thermal storage mechanism has a disassembly mechanism at its top. An insulation layer is fixedly connected to the inner wall of the fixing frame, and the thermal storage tank body is fixedly connected to the inner wall of the insulation layer. Four fixing plates are fixedly connected to the bottom of the fixing frame. A hot fluid pipe and a cold fluid pipe are fixedly connected to the inner wall of the thermal storage tank. A limit ring is fixedly connected to the inner wall of the thermal storage tank. A lid is snapped onto the top of the thermal storage tank body, and a connector is fixedly connected to the top of the lid. The limit ring prevents a circular plate from falling into the thermal storage tank body, thus preventing damage to the device's function.

[0007] Furthermore, a second connector is fixedly connected to the top of the cover, a circular plate is snapped onto the top of the limiting ring, and a handle is fixedly connected to the top of the circular plate. By setting the second connector, it is convenient to connect to external pipes, ensuring the normal operation of the device.

[0008] Furthermore, a fixed column is fixedly connected to the bottom of the circular plate, and a heat storage plate is fixedly connected to the inner wall of the fixed column. There are two heat storage plates in total. By setting up heat storage plates, when the hot fluid flows through the heat storage plate, it exchanges heat with the phase change material inside the heat storage plate through the heat exchange holes on the plate surface. The heat of the hot fluid is transferred to the phase change material, causing the temperature of the phase change material to rise. When the phase change temperature is reached, the phase change material undergoes a phase change, for example, from solid to liquid. This process absorbs a large amount of heat and stores it.

[0009] Furthermore, the heat storage plate has heat exchange holes inside, and a second heat exchange hole is also provided inside the heat storage plate. The inner wall of the second heat exchange hole is in contact with the outer wall of the hot fluid pipe, and the inner wall of the second heat exchange hole is in contact with the outer wall of the cold fluid pipe. By providing the heat exchange holes and the second heat exchange hole, the heat storage plate can easily absorb and store the heat of the fluid input into the heat storage tank.

[0010] Furthermore, the disassembly mechanism includes a fixing block fixedly connected to the outer wall of the cover, and a fixing post two fixedly connected to the bottom of the fixing block. By setting the fixing post two fixedly connected to the bottom of the fixing block two, a fixing block two is fixedly connected to the outer wall of the insulation layer, and a fixing block three is fixedly connected to the outer wall of the insulation layer. The fixing block three has a groove inside. By setting the fixing post two and the fixing block two fixedly connected to the cover, the cover is fixed to the top of the device and will not be displaced during the operation of the device.

[0011] Furthermore, a sliding groove is provided inside the fixing block three, and a telescopic rod is fixedly connected to the inner wall of the groove. A clamping block is fixedly connected to the side of the telescopic rod away from the inner wall of the groove. A spring is sleeved on the outer surface of the telescopic rod, and a fixing post three is fixedly connected to the outer wall of the clamping block. The outer surface of the fixing post three is slidably connected to the inner wall of the sliding groove two. By setting the clamping block, the fixing block two and the fixing post two are clamped, thereby fixing the cover.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model incorporates a heat storage plate. When heat storage is required, an external pipe is first connected to connector two, and hot fluid is transported to the inside through the hot fluid pipe. As the hot fluid passes through the heat storage plate, its heat is absorbed into the heat storage plate through the heat exchange holes two inside the heat storage plate. Then, an external pipe is connected to connector one, and cold fluid is transported through the cold fluid pipe. The cold fluid passes through the heat storage plate and its heat is absorbed through the heat exchange holes inside the heat storage plate, thus heating the cold fluid. When the heat storage plate needs to be removed, this mechanism, through its vertical structure design, allows the heat storage tank to make full use of vertical space, resulting in a larger heat storage volume compared to horizontal heat storage tanks. At the same time, vertical heat storage tanks are more likely to form natural thermal stratification, which helps to improve the overall efficiency of the heat storage tank.

[0014] 2. This utility model incorporates a clamping block. When the internal heat storage plate needs to be replaced, the cover must first be opened. Then, the fixed column three is manually moved along the slide groove, which in turn moves the clamping block, thus squeezing the spring and telescopic rod. When the fixed column three is engaged below the slide groove, the cover can be manually removed, moving the fixed block, which in turn moves the fixed column two, and then the fixed block two. Since the heat storage plate may age during long-term heat circulation, affecting the heat storage and release efficiency of the heat storage tank, this mechanism allows for easy disassembly of the cover, enabling the replacement of the internal heat storage plate and ensuring the long-term stable operation of the heat storage tank.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a vertical phase change thermal storage tank, including a thermal storage mechanism 1 and a fixing frame 101. A disassembly mechanism 2 is provided at the top of the thermal storage mechanism 1. An insulation layer 102 is fixedly connected to the inner wall of the fixing frame 101, and the thermal storage tank body 103 is fixedly connected to the inner wall of the insulation layer 102. Fixing plates 104 are fixedly connected to the bottom of the fixing frame 101. The insulation layer 102 ensures that the heat inside the device will not be lost to the outside. Four fixing plates 104 are provided. A hot fluid pipe 105 and a cold fluid pipe 106 are fixedly connected to the inner wall of the thermal storage tank body 103. Limiting rings 107 are fixedly connected to the inner wall of the thermal storage tank body 103 to secure it. A circular plate 111 is used to prevent it from falling to the bottom of the device. A cover 108 is snapped onto the top of the heat storage tank body 103. A connector 109 and a connector 110 are fixedly connected to the top of the cover 108. A limit ring 107 is snapped onto the top of the circular plate 111. By setting the circular plate 111 to be connected to the heat storage plate 114, the heat storage plate 114 can be removed at the same time as the circular plate 111. A handle 112 is fixedly connected to the top of the circular plate 111. A fixing column 113 is fixedly connected to the bottom of the circular plate 111. A heat storage plate 114 is fixedly connected to the inner wall of the fixing column 113. There are two heat storage plates 114. The heat storage plates 114 absorb the heat of the fluid flowing into the device.

[0026] The hot fluid flows into the device through the hot fluid pipe 105, and when it passes through the heat storage plate 114, the heat storage plate 114 absorbs the heat inside the hot fluid and stores it inside the heat storage plate 114. Then, it transfers heat to the fluid inside the cold fluid pipe 106 and heats the cold fluid inside the cold fluid pipe 106.

[0027] The heat storage plate 114 has heat exchange holes 116 and 117. The inner wall of heat exchange hole 116 contacts the outer wall of hot fluid pipe 105, and the inner wall of heat exchange hole 117 contacts the outer wall of cold fluid pipe 106. Through heat exchange holes 116 and 117, heat is transferred and absorbed by the fluids inside the two pipes respectively. The disassembly mechanism 2 includes a fixing block 201 fixedly connected to the outer wall of the cover 108. A fixing column 202 is fixedly connected to the bottom of the fixing block 201, and a fixing block 203 is fixedly connected to the bottom of the fixing column 202. A fixing block 304 is fixedly connected to the outer wall of the insulation layer 102. A groove 205 is provided inside the fixing block 304. By setting the fixing block 203, when the fixing block 203 is clamped, the cover 108 will be fixed above the device and will not be displaced.

[0028] The internal heat exchange holes 116 and 117 respectively absorb heat from the cold fluid pipe 106 and the hot fluid pipe 105. Meanwhile, the cover 108 can be clamped inside the fixing block 204 to ensure that the cover 108 will not fall off accidentally during the operation of the device.

[0029] The fixed block 204 has a groove 206 inside. A telescopic rod 207 is fixedly connected to the inner wall of the groove 205. A clamping block 211 is fixedly connected to the side of the telescopic rod 207 away from the inner wall of the groove 205. A spring 208 is sleeved on the outer surface of the telescopic rod 207. By setting the spring 208 to compress the clamping block 211, the clamping block 211 clamps the fixed post 202 and the fixed block 203. A fixed post 209 is fixedly connected to the outer wall of the clamping block 211. The outer surface of the fixed post 209 is slidably connected to the inner wall of the groove 210.

[0030] Manually move the fixing post 209 along the slide 206, and then lock the fixing post 209 in place through the slide 206, thereby locking the clamping block 211. Then, the fixing post 202 and fixing block 203 held by the clamping block 211 can be removed, thereby removing the cover 108 and disassembling and replacing the internal heat storage plate 114.

[0031] One specific application of this embodiment is:

[0032] When heat storage is required, firstly, an external pipe is connected to connector 110, and hot fluid is supplied to the interior through hot fluid pipe 105. As the hot fluid passes through the heat storage plate 114, it absorbs heat through the heat exchange holes 117 inside the heat storage plate 114. Then, an external pipe is connected to connector 109, and cold fluid is supplied through cold fluid pipe 106. The cold fluid passes through the heat storage plate 114 and absorbs heat through the heat exchange holes 116 inside the heat storage plate 114, thus increasing the heat storage capacity of the cold fluid. When it is necessary to remove the heat storage plate 114, first open the cover, then move the circular plate 111 by using the handle 112, which in turn moves the heat storage plate 114 upward, thereby detaching the heat storage plate 114 from the overall device for replacement. This mechanism, through its vertical structure design, allows the heat storage tank to make full use of vertical space, resulting in a larger heat storage volume compared to horizontal heat storage tanks. At the same time, vertical heat storage tanks are more likely to form natural thermal stratification, which helps to improve the overall efficiency of the heat storage tank.

[0033] When the internal heat storage plate 114 needs to be replaced, the cover 108 must first be opened. First, the fixing column 209 is moved manually along the slide groove 206, which in turn moves the clamping block 211, thereby squeezing the spring 208 and the telescopic rod 207. When the fixing column 209 is inserted under the slide groove 206, the cover 108 can be removed manually, moving the fixing block 201, which in turn moves the fixing column 202, and then the fixing block 203. Since the heat storage plate may age during long-term heat circulation, which will affect the heat storage and heat release efficiency of the heat storage tank, this mechanism can easily remove the cover to replace the internal heat storage plate, ensuring that the heat storage tank can operate stably for a long time.
