Description

Technical Field

[0001] This invention relates to the field of energy storage material and building structure integration technology, and in particular to a modular modified concrete energy storage device. Background Technology

[0002] Against the backdrop of the increasingly urgent global energy transition and building energy conservation needs, integrating phase change energy storage technology with building materials to develop integrated building components that combine load-bearing function and energy storage performance has become an important development direction for reducing building energy consumption and improving energy utilization efficiency. However, the design of the internal heat conduction structure of traditional energy storage components has some shortcomings. Cement-based materials themselves have low thermal conductivity. Due to the inadequate design of the internal heat conduction structure of traditional energy storage components, heat diffuses slowly and unevenly inside the energy storage block, which can easily lead to local overheating or insufficient heat storage. When multiple energy storage components need to be spliced ​​together to form a large-scale energy storage array, the design defects of the heat conduction connection structure between adjacent components result in high contact thermal resistance. It is difficult to efficiently transfer and evenly distribute heat throughout the entire area, which cannot meet the large-scale heat storage and supply needs of large buildings, industrial plants and other large-scale heat storage and supply. In summary, this study aims to address the problems of low energy storage density, poor thermal conductivity, and insufficient heat storage and release regulation capabilities of traditional concrete, and provides a modified concrete energy storage block and its matching heat storage structure that combine structural load-bearing performance with high-efficiency energy storage function.

The energy storage block is equipped with a heat conduction mechanism and a main channel, and the energy storage block transfers heat to the main channel through the heat conduction mechanism. The front of the energy storage block is covered by an installation plate, which covers one end of the front of the main channel. The back of the mounting plate is provided with a temperature control mechanism and a transducer control mechanism, both of which are located within the main channel.

[0005] Preferably, the heat conduction mechanism includes a heat conduction pipe, a metal heat conduction pipe, and a contact heat conduction plate; The energy storage block is equipped with crisscrossing heat conduction pipes, and metal heat conduction pipes are fixedly installed inside the heat conduction pipes. The heat conduction pipes and metal heat conduction pipes form a double-layer sleeve structure. The metal heat conduction pipes extend outward to the four sides of the energy storage block, and the outer ends of the metal heat conduction pipes are covered with contact heat conduction plates, which are embedded in the side walls of the energy storage block. The main channel is a straight pipe that extends toward the front of the energy storage block and is fixedly connected to the heat conduction channel.

[0006] Preferably, multiple heat-conducting plates extend from the outside of the heat-conducting pipe, and each heat-conducting plate extends into the interior of the energy storage block.

[0007] Preferably, the heat-conducting pipe is an integral cross-shaped pipe formed by interlacing in the same plane.

[0008] Preferably, the temperature control mechanism includes a main board, a control panel, and a socket. The main board is fixedly installed on the back of the mounting plate, and the control panel and the socket cover the front of the main board. The main board is fixedly installed at one end of the front of the transducer control mechanism.

[0009] Preferably, the energy conversion control mechanism includes a conversion protection unit, a thermoelectric power generation module, a high thermal conductivity graphite block, and a temperature probe, wherein the conversion protection unit is connected to the main board; The conversion protection unit, thermoelectric power generation module, and high thermal conductivity graphite block are connected in sequence from right front to back.

[0011] Preferably, a thermal insulation protective layer is fixedly connected to the energy storage block.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this modular modified concrete energy storage device, the cross-shaped heat conduction pipe plays a core conductive role. The heat stored in the phase change material is gathered to the heat conduction pipe through the heat conduction plate, and then transferred to the metal heat conduction pipe. The core function of the contact heat conduction plate is to increase the contact area between the metal heat conduction pipes inside the adjacent energy storage blocks when multiple energy storage blocks are spliced. Specifically, when multiple energy storage blocks are assembled by splicing protrusions and grooves, the contact heat conduction plates of adjacent energy storage blocks are in contact with each other, thereby improving the heat conduction efficiency between the metal heat conduction pipes. Together with the heat conduction pipe and the metal heat conduction pipe, the heat conduction of each energy storage block is realized, forming a unified heat conduction network. This ensures that heat is efficiently transferred, evenly distributed, or centrally output among multiple energy storage blocks to meet the heat demand of different areas.

[0013] 2. This modular modified concrete energy storage device integrates the energy conversion and regulation mechanism into the temperature control and regulation mechanism, which is located within the main channel during installation. Its core utilizes the thermoelectric effect to recover and reuse heat. A high thermal conductivity graphite block rapidly transfers the temperature of the metal heat pipe to the thermoelectric module. Based on the Seebeck effect, the thermoelectric module converts the temperature difference into electrical energy. The conversion protection unit, in addition to stabilizing the output power and providing overcurrent protection to ensure stable power, can also regulate the voltage under the control of the main board to adapt to the power needs of external equipment. Simultaneously, it can feed back the recovered electrical energy to the main board. After the main board regulates the power to a suitable voltage through the conversion protection unit, it controls the socket to connect to external equipment, providing power to both the external equipment and the temperature control system itself. Furthermore, the conversion protection unit can monitor the operating status of the temperature control and regulation mechanism. When abnormal temperature or circuit failure occurs, it triggers a protection mechanism to cut off relevant circuits and ensure operational safety. Attached Figure Description

[0021] Please see Figure 1-6 The present invention provides a technical solution: a modular modified concrete energy storage device, including an energy storage block 1. The energy storage block 1 is made of high-strength silicate cement as the matrix, and incorporates surface-modified phase change materials such as fatty acid composite phase change materials, thermally conductive reinforcing fillers such as graphite powder, carbon fiber and heat storage aggregate. The energy storage block 1 has both excellent heat storage performance and building load-bearing capacity. One end of the energy storage block 1 is fixedly connected to a protrusion 2, and the other end of the energy storage block 1 is provided with a groove 3. A heat insulation and protective layer 4 is fixedly connected to the energy storage block 1. A heat conduction mechanism is provided inside the energy storage block 1. The heat conduction mechanism includes a heat conduction pipe 5, which is fixedly connected inside the energy storage block 1. The energy storage block is vertically stacked, and the heat conduction pipe 5 has a cross-shaped structure on the vertical plane. A metal heat conduction pipe 7 is fixedly connected inside the heat conduction pipe 5, and a contact heat conduction plate 8 is fixedly connected to each end of the metal heat conduction pipe 7 extending outward. The heat-conducting pipe 5 and the metal heat-conducting pipe 7 form a double-layer sleeve structure. The metal heat-conducting pipe 7 extends outward to the four sides of the energy storage block 1, and the outer ends of the metal heat-conducting pipe 7 are covered with contact heat-conducting plates 8. The contact heat-conducting plates 8 are embedded in the side walls of the energy storage block 1. The metal heat-conducting pipe 7 and the heat-conducting pipe 5 form a cross-shaped outward-extending sleeve structure. The contact heat-conducting plates 8 are embedded in the upper, lower, left, and right side walls of the energy storage block 1, and the contact heat-conducting plates 8 are flush with the side walls of the energy storage block 1. When adjacent energy storage blocks 1 are mated together, the positions of the adjacent contact heat-conducting plates 8 correspond one-to-one and are mated together.

[0022] The main channel 9 is a straight pipe that extends towards the front of the energy storage block 1. The main channel 9 is fixedly connected to the heat conduction channel 5. The heat energy of the metal heat conduction pipe 7 is transferred to the front of the energy storage block 1 through the main channel 9, and the heat energy is converted and utilized.

[0023] The energy storage block 1 uses high-strength silicate cement as the matrix, and the fatty acid composite phase change material with surface modification treatment is the core heat storage carrier. Combined with thermally conductive reinforcing fillers such as graphite powder and carbon fiber, as well as heat storage aggregate, it realizes the integration of load-bearing and heat storage functions. When there is usable heat in the environment, such as solar heat collection and industrial waste heat, the heat is first transferred to the metal heat pipe 7, and then the heat is conducted out by the cross-shaped heat pipe 5 and transferred to the contact heat plate 8. The energy conversion and control mechanism generates electricity through the temperature difference of energy storage block 1, and controls the power supply through the temperature control mechanism. Both the energy conversion and control mechanism are located in the main channel 9 on the front of energy storage block 1, and are used to utilize and release the heat energy inside energy storage block 1.

[0024] Several heat-conducting plates 6 are fixedly connected to the heat-conducting pipe 5; the heat-conducting plates 6 extend outward from the outside of the heat-conducting pipe 5, and each heat-conducting plate 6 extends into the energy storage block 1.

[0025] The heat-conducting plates 6 on the heat-conducting pipe 5 increase the contact area with the base material of the energy storage block 1, allowing heat to diffuse rapidly into the interior of the energy storage block 1. At this time, the phase change material absorbs heat and undergoes a phase change, using the latent heat of phase change to stably store the heat. The heat insulation and protection layer 4 outside the energy storage block 1 can reduce the loss of stored heat and ensure the stability of heat storage. A main channel 9 is fixedly connected to an energy storage block 1 in an area where energy is needed. The main channel 9 is fixedly connected to a heat conduction channel 5. An installation plate 10 is fixedly connected to the energy storage block 1. Several threaded grooves are opened on the installation plate 10. The mounting plate 10 is provided with a temperature control adjustment mechanism, which includes a main board 11. The main board 11 is fixedly mounted on the mounting plate 10. A control panel 12 is fixedly connected to the main board 11. A socket 13 is fixedly connected to the main board 11. Motherboard 11: STM32F103C8T6, which meets the intelligent control requirements of temperature probe signal acquisition, control panel command interaction, conversion protection unit and energy usage module, and industrial-grade performance is adapted to building outdoor / semi-outdoor scenarios. Control panel 12: Made of Kunlun Tongtai TPC7062Ti, which is dust resistant and can withstand minor impacts, and is suitable for the on-site operation requirements of building energy storage blocks. It can intuitively display temperature data and equipment operating status. The temperature control mechanism is equipped with a conversion control mechanism, which is integrated into one unit. The conversion control mechanism includes a conversion protection unit 14, which is fixedly connected to the main board 11. A thermoelectric power generation module 15 is fixedly connected to the conversion protection unit 14, and a high thermal conductivity graphite block 16 is fixedly connected to the thermoelectric power generation module 15. Therefore, starting from the front of the energy storage block 1, the conversion protection unit 14, the thermoelectric power generation module 15, and the high thermal conductivity graphite block 16 are connected sequentially from right front to back.

[0026] The protection unit 14, thermoelectric generator module 15, high thermal conductivity graphite block 16 and temperature probe 18 are all located inside the main channel 9. Heat and temperature are transferred through the main channel 9, which facilitates the control and thermoelectric conversion of the energy conversion and temperature control mechanisms.

[0027] A temperature probe 18 is fixedly connected to the main board 11, and the other end of the temperature probe 18 is fixedly connected to the high thermal conductivity graphite block 16; through the overall temperature control adjustment mechanism, the power supply voltage of the generator is automatically controlled to keep the power supply voltage stable.

[0028] Conversion Protection Unit 14: Internally, voltage regulation is achieved through LM2596S-ADJ+ self-resetting fuse to regulate the output voltage of the thermoelectric generator module, match the power demand of external electrical equipment, and provide dual protection against overcurrent and surge. Thermoelectric module 15: TEC1-12706 semiconductor thermoelectric generator, which can stably convert temperature difference into electrical energy, and the power meets the self-power supply requirements of the temperature control system. In the entire power generation structure, it converts heat energy into electrical energy and plays the role of power generation. High thermal conductivity graphite block 16: GTS-200 flexible high thermal conductivity graphite block. The flexible material can be closely attached to the surface of the metal heat pipe 7, which greatly reduces the contact thermal resistance and quickly transfers the temperature of the metal heat pipe to the thermoelectric power generation module and temperature probe, achieving efficient heat conduction. It also enables the transfer of the internal heat energy of the energy storage block 1 absorbed by the metal heat pipe 7, playing the role of energy conversion bridging. When the temperature control mechanism is fixedly installed on the mounting plate 10, the energy conversion control mechanism is set in the main channel 9, and the high thermal conductivity graphite block 16 is attached to the metal heat pipe 7. The metal heat pipe 7 and the high thermal conductivity graphite block 16 are attached to achieve efficient heat transfer, so that the heat energy in the energy storage block 1 is transferred to the high thermal conductivity graphite block 16 through the metal heat pipe 7. Then, the thermal energy is converted into electrical energy by the thermoelectric power generation module 15, and finally, the control socket 13 on the main board 11 provides power to the external device.

[0029] The temperature control mechanism is fixedly connected to the energy storage block 1 via the mounting plate 10. The core is intelligently controlled via the main board 11. The temperature probe 18 is fixed on the high thermal conductivity graphite block 16. Because the high thermal conductivity graphite block 16 is tightly attached to the metal heat pipe 7 and has high thermal conductivity, it can accurately detect the temperature of the metal heat pipe 7 in real time and transmit the signal to the main board 11. After the user inputs the temperature control command through the control panel 12, the main board 11 compares the received temperature signal with the preset command and controls the working state of the socket 13. The socket 13 is used to connect external electrical equipment. Several bolts 17 are rotatably connected through the main board 11, and the bolts 17 are threadedly connected to the threaded grooves on the mounting plate 10. At the installation and overall coordination level, each energy storage block 1 can be quickly spliced ​​and assembled by the cooperation of the protrusion 2 and the groove 3 to form a large-area heat storage and conduction array. The bolt 17 connection method of the mounting plate 10 facilitates the disassembly and maintenance of the temperature control adjustment mechanism. The protrusion 2 and the groove 3 can be flat grooves, and dovetail grooves are preferred.

[0030] Similarly, the vertical assembly of the energy storage block 1 can also be achieved by setting grooves 3 and protrusions 2. In order to ensure a smooth assembly, the upper and lower surfaces of the energy storage block 1 are chosen to be flat. During construction, it can be formed into a wall by masonry. Adhesive or cement mortar is applied between adjacent energy storage blocks 1 to form a whole. The assembly of grooves 3 and protrusions 2 is to form a force linkage before masonry, which facilitates the subsequent integration of the wall masonry. The wall masonry is solid and is mainly completed through on-site construction. The main problems solved by this device are energy storage and power supply.

[0031] It should be noted that this device is designed to assemble multiple energy storage blocks 1 into smaller modules, making them more compact, easier to manufacture, and easier to replace and maintain. However, this also brings other problems. The modular assembly structure results in uneven heat distribution among the various energy storage blocks 1, and hinders heat transfer. The modular energy storage blocks 1 make the overall assembly and manufacturing of this device more convenient. At the same time, the heat stored in the energy storage blocks 1 is released and converted through the heat conduction pipes 5 and metal heat conduction pipes 7, and the contact heat conduction plate 8 provides a smoother conduction structure, making the heat from the different connected energy storage blocks 1 more uniform.

[0032] Working principle: Energy storage block 1 uses high-strength silicate cement as the matrix, and the fatty acid composite phase change material with surface modification treatment inside is the core heat storage carrier. Combined with thermally conductive and reinforcing fillers such as graphite powder and carbon fiber, as well as heat storage aggregate, it realizes the integration of load-bearing and heat storage functions.

[0033] When the energy storage block 1 absorbs heat: When there is usable heat in the environment, such as solar thermal collection, industrial waste heat, etc., the heat is absorbed by the energy storage block 1 and heat transfer is formed. The heat is first transferred to the metal heat pipe 7, and then the heat is discharged and transferred to the contact heat plate 8 by the cross-shaped heat pipe 5. Meanwhile, the several heat-conducting plates 6 on the heat-conducting pipe 5 increase the contact area between the heat-conducting pipe 5 and the base material of the energy storage block 1, allowing the heat in the heat-conducting pipe 5 to diffuse rapidly into the energy storage block 1. At this time, the phase change material absorbs heat and undergoes a phase change, using the latent heat of phase change to stably store the heat. The heat insulation and protection layer 4 outside the energy storage block 1 can reduce the loss of stored heat and ensure the heat storage stability of the energy storage block 1.

[0034] When heat needs to be released to the target area or heat regulation is required, the cross-shaped heat conduction pipe 5 plays a core conductive role. The heat stored in the phase change material is gathered to the heat conduction pipe 5 through the heat conduction plate 6, and then transferred to the metal heat conduction pipe 7 by the heat conduction pipe 5. The core function of the contact heat conduction plate 8 is to increase the contact area between the metal heat conduction pipes 7 inside the adjacent energy storage blocks 1 when multiple energy storage blocks 1 are spliced ​​together.

[0035] Specifically, when multiple energy storage blocks 1 are assembled by splicing protrusions 2 and grooves 3, the contact heat-conducting plates 8 of adjacent energy storage blocks 1 are in contact with each other, thereby improving the heat conduction efficiency between metal heat-conducting pipes 7. Together with the heat-conducting pipes 5 and metal heat-conducting pipes 7, the heat conduction of each energy storage block 1 is realized, so that the heat energy in different energy storage blocks 1 forms a unified heat conduction network, ensuring that heat is efficiently transferred, evenly distributed or concentratedly output among multiple energy storage blocks 1, meeting the heat demand of different areas. Especially when the temperature absorption is uneven, such as when the heat medium in contact at the front has a large amount of heat energy, the heat transfer becomes lower as it is transferred further back. Therefore, the heat-conducting pipes 5 and metal heat-conducting pipes 7 of this device form a double-layer heat-conducting pipe. Through the contact heat-conducting plates 8 that transfer heat more efficiently, the temperature transfer and distribution between multiple different energy storage blocks 1 are realized, so that the temperature between the spliced ​​energy storage blocks 1 tends to be consistent.

[0036] The temperature control mechanism is fixedly connected to the energy storage block 1 via the mounting plate 10. The core is intelligently controlled via the main board 11. The temperature probe 18 is fixed on the high thermal conductivity graphite block 16. Because the high thermal conductivity graphite block 16 is tightly attached to the metal heat pipe 7 and has high thermal conductivity, it can accurately detect the temperature of the metal heat pipe 7 in real time and transmit the signal to the main board 11. After the user inputs the temperature control command through the control panel 12, the main board 11 compares the received temperature signal with the preset command and controls the working state of the socket 13. The socket 13 is used to connect external electrical equipment. The energy conversion and regulation mechanism is integrated into the temperature control and regulation mechanism and is installed in the main channel 9. The core utilizes the thermoelectric effect to realize heat recovery and reuse. The high thermal conductivity graphite block 16 quickly transfers the temperature of the metal heat pipe 7 to the thermoelectric module 15. The thermoelectric module 15 converts the temperature difference into electrical energy based on the Seebeck effect. In addition to stabilizing the output power and protecting it from overcurrent to ensure power stability, the conversion protection unit 14 can also complete voltage regulation under the control of the main board 11 to adapt to the power demand of external electrical equipment. At the same time, it can feed back the recovered electrical energy to the main board 11. After the main board 11 regulates the power to a suitable voltage through the conversion protection unit 14, the control socket 13 connects to the external electrical equipment to supply power to the external electrical equipment and the temperature control system itself. In addition, the conversion protection unit 14 can also monitor the working status of the temperature control and regulation mechanism. When abnormal temperature or circuit failure occurs, the protection mechanism is triggered to cut off the relevant circuit to ensure safe operation. This device heats the energy storage block 1 through an external heat medium. After the energy storage block 1 absorbs heat energy, the heat is transferred and redistributed through the heat conduction pipe 5 and the metal heat conduction pipe 7, so that the heat energy stored in the multiple interconnected energy storage blocks 1 is basically the same.

[0037] When electricity is needed, the energy storage block 1 transfers heat to the high thermal conductivity graphite block 16 via the metal heat pipe 7. The thermoelectric generator module 15 then converts the heat energy of the high thermal conductivity graphite block 16 into electrical energy, which is finally supplied to external devices via the control socket 13 on the main board 11. Simultaneously, the power supply status of the protection unit 14 is switched, and power is cut off in case of abnormal temperature or voltage, ensuring the overall stable operation of the device.

[0038] In terms of installation and overall coordination, the energy storage blocks 1 of this device can be quickly assembled by the cooperation of the protrusions 2 and the grooves 3 to form a large-area heat storage and conduction array. The bolt 17 connection method of the mounting plate 10 facilitates the disassembly and maintenance of the temperature control mechanism. Energy storage block 1 uses high-strength silicate cement as the matrix, and incorporates surface-modified phase change materials, thermally conductive and enhanced fillers and heat storage aggregates. While meeting the mechanical performance requirements of building load-bearing components, it also has excellent phase change heat storage capacity. There is no need to install additional independent energy storage equipment and load-bearing structures, which greatly reduces the building space occupancy rate and reduces the overall construction cost and space planning difficulty. The double-layer heat conduction structure composed of cross-shaped heat conduction pipes and metal heat conduction pipes 7, combined with multiple sets of heat conduction plates 6 to increase the contact area with the energy storage block 1 substrate, realizes the rapid and uniform diffusion of heat inside the energy storage block 1. The contact heat conduction plate 8 can increase the contact area of ​​the metal heat conduction pipes 7 of adjacent energy storage blocks 1 when multiple energy storage blocks 1 are spliced ​​together. Together with the main channel 9, a fully connected heat conduction network is formed to ensure that heat is efficiently transferred and evenly distributed in the large-scale energy storage array, which is suitable for the heat storage and supply needs of different areas such as residential buildings, industrial plants, and large venues. The temperature control mechanism monitors the temperature of the metal heat pipe 7 in real time through the temperature probe 18. The main board 11 combines preset instructions and uses the conversion protection unit 14 to precisely regulate the voltage, so that the energy use module can stably supply power to external electrical equipment. The energy conversion control mechanism uses the thermoelectric generator module 15 to convert the temperature of the metal heat pipe 7 and the environment into electrical energy, thereby improving the comprehensive utilization of energy.
