Description

Technical Field

[0001] This invention relates to the field of energy storage device technology, specifically to a modular phase change material thermal energy storage device. Background Technology

[0002] Modular phase change material (PCM) thermal energy storage technology integrates independent unit modules encapsulated with solid-liquid PCM materials to form a flexible, expandable, and maintainable energy storage system. This technology utilizes the latent heat absorption or release properties of PCM materials during phase change to achieve efficient thermal energy storage and stable release. It boasts advantages such as high energy density, low temperature fluctuations, and flexible structural adaptability, and has become one of the core energy storage technologies in fields such as industrial waste heat recovery, building energy-efficient heating, and grid peak-valley regulation.

[0003] In existing modular phase change energy storage devices, the phase change modules are mostly statically arranged. Under repeated melting and solidification cycles, the internal phase change materials are easily affected by gravity, resulting in sedimentation and stratification, bottom agglomeration, and wall adhesion. This increases the heat exchange resistance, causes a decrease in heat exchange efficiency, and a deterioration in the stability of heat storage and release. The long-term energy storage and heat release performance is significantly reduced, which cannot meet the requirements for long-term efficient and stable operation. Summary of the Invention

[0004] This invention provides a modular phase change material thermal energy storage device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention discloses a modular phase change material thermal energy storage device, including a U-shaped base, a fixed cylinder installed on the U-shaped base, an inlet pipe and an outlet pipe respectively rotatably passing through both ends of the fixed cylinder, a phase change module detachably connected to the side of the inlet pipe and the outlet pipe that are close to each other, the phase change module includes several phase change modules connected end to end, a water pipe passing through the phase change module, connectors provided at both ends of the water pipe, and a vibration mechanism provided on the outer periphery of the fixed cylinder.

[0006] By adopting the above technical solution, the vibration of the vibration mechanism can be uniformly transmitted to each phase change module inside through the fixed cylinder wall, breaking the long-term static arrangement of the phase change modules. This can effectively suppress the sedimentation and stratification, bottom agglomeration, and inner wall adhesion phenomena caused by gravity during the repeated melting and solidification of phase change materials in the process of hot and cold cycles.

[0007] Preferably, a drive box is fixedly installed on the left side wall of the U-shaped seat.

The vibration mechanism includes an arc-shaped vibration plate, and the connecting block is fixedly connected to the arc-shaped vibration plate.

[0010] By adopting the above technical solution: the follower block and the connecting block slide along the groove of the fixed box, and drive the arc-shaped vibration plate to move back and forth synchronously.

[0012] By adopting the above technical solution: the arc-shaped vibration plate moves, and under the elastic buffering and reset action of spring one and piston plate one, continuous elastic knocking vibration is formed, and the vibration is transmitted to each phase change module inside through the fixed cylinder as a whole.

[0013] Preferably, a support column is fixedly installed on the U-shaped base, and an air box is fixedly installed on the support column. The air box is fixedly connected to the right side wall of the U-shaped base. A push plate is slidably installed inside the air box. A push rod is fixedly installed at one end of the push plate. The push rod slidably extends out of the air box, and an L-shaped rod is fixedly installed at the other end of the push rod. A second sliding groove is opened on the front side wall of the fixed box. The L-shaped rod extends from the second sliding groove into the fixed box. The L-shaped rod is slidably connected to the second sliding groove and is fixedly connected to the follower block.

[0014] By adopting the above technical solution: during the linear reciprocating sliding process, the follower block synchronously drives the L-shaped rod to slide along the second slide groove, and the L-shaped rod pulls the push rod and the push plate to perform reciprocating push-pull motion inside the air box.

[0016] By adopting the above technical solution, the reciprocating movement of the air pusher plate, combined with the elastic restoring action of the second spring, causes periodic air intake and blowing actions to be formed inside the air box.

[0018] By adopting the above technical solution: when the phase change module rotates synchronously with the water inlet pipe, both rotating pipe one and rotating pipe two can rotate, thereby driving the phase change module to rotate, further improving the overall heat exchange efficiency and heat storage and release balance.

[0019] Preferably, a hollow disc is fixedly installed on the inner wall of the fixed cylinder. A circular groove is opened on the left side of the hollow disc, and a circular plate is installed in the groove. The circular plate is fixedly connected to two L-shaped tubes.

[0020] By adopting the above technical solution, the meshing wheel moves along the mating belt on the inner wall of the hollow disc, and rotates on its own axis while revolving around the center, which allows the internal phase change material to tumble and reposition in all directions, thus avoiding static accumulation from the root.

[0021] Preferably, a circular ring plate is fixedly mounted on the circular plate, and a notch is provided on the circular ring plate. One side of the notch is sloping. A striking component is provided on the side of the rotating disk near the circular plate. The striking component includes a second striking head, which cooperates with the circular ring plate.

[0022] By adopting the above technical solution, the slope of the circular plate plays a smooth guiding and transitioning role, ensuring the smooth climbing of the second striking head, and triggering the fixed-point elastic striking only when it rotates to the notch position.

[0023] Preferably, the striking assembly further includes a sleeve two, which is fixedly mounted on the rotating disk. A piston plate two is disposed inside the sleeve two, and a piston rod two is fixedly mounted on the piston plate two. The piston rod two slides out of the sleeve two, and a spring three is sleeved on the piston rod two. The spring three is fixedly connected to the piston plate two and the sleeve two, and a striking head two is fixedly mounted on the other end of the piston rod two.

[0024] By adopting the above technical solution: when the second striking head moves to the notch position along the rotation trajectory, it loses the support and limit of the ring plate and quickly pops out under the elastic reset action of the third spring, forming a precise elastic striking action.

[0025] In summary, compared with the prior art, the present invention provides a modular phase change material thermal energy storage device with the following beneficial effects: By setting a vibration mechanism on the outer periphery of the fixed cylinder, the vibration can be uniformly transmitted to each internal phase change module through the cylinder wall, breaking the long-term static arrangement of the phase change modules. This effectively suppresses the sedimentation and stratification, bottom agglomeration, and inner wall adhesion phenomena caused by gravity during the repeated melting and solidification of the phase change material in the cold and hot cycle. It makes the phase change material distribution more uniform and the phase change reaction more synchronous, significantly improving the temperature stability of the heat storage and release process, ensuring stable and reliable energy storage and heat release performance under long-term operation, and meeting the requirements for long-term efficient and stable operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] Example 1: An embodiment of the present invention provides a modular phase change material thermal energy storage device, such as... Figures 1-9 As shown, it includes a U-shaped base 1, on which a fixed cylinder 4 is installed. A water inlet pipe 16 and a water outlet pipe 7 are respectively rotatably installed through both ends of the fixed cylinder 4. A phase change module is detachably connected to the side of the water inlet pipe 16 and the water outlet pipe 7 that are close to each other. The phase change module includes several phase change modules 31 connected end to end. A water passage pipe 36 is installed through the phase change module 31. Connectors are provided at both ends of the water passage pipe 36. A vibration mechanism is provided on the outer periphery of the fixed cylinder 4.

[0032] Among them, several support rods 11 are fixedly installed at the lower end of the U-shaped seat 1.

[0033] The connectors can be sealed snap-fit ​​joints or quick-connect sealing joints, which are easy to install and remove and have good sealing and leak-proof performance.

[0034] The working principle and beneficial effects of the above technical solution are as follows: When in use, the heat exchange medium is introduced through the inlet pipe 16, flows through the water pipe 36 inside each phase change module 31, and then flows out through the outlet pipe 7, exchanging heat with the phase change material inside the phase change module 31 to realize the storage and release of heat energy; the phase change module can be detachably assembled between the inlet pipe 16 and the outlet pipe 7, and is assembled as a whole inside the fixed cylinder 4 above the U-shaped seat 1. The vibration mechanism set on the outer periphery of the fixed cylinder 4 can generate mechanical vibration and transmit the vibration to each phase change module 31 inside the fixed cylinder 4, breaking the long-term static state of the phase change material.

[0035] A vibration mechanism is set on the outer periphery of the fixed cylinder 4, and the vibration can be evenly transmitted to each phase change module 31. This effectively suppresses the sedimentation, stratification, bottom agglomeration, and inner wall adhesion phenomena that occur in the phase change material during repeated melting, solidification, and thermal cycling. It also prevents the formation of a solidified insulation layer, reduces heat exchange resistance, and avoids the attenuation of heat exchange efficiency over long-term operation, ensuring stable heat storage and release performance. The phase change module is composed of several phase change modules 31 spliced ​​end to end, and the whole adopts a detachable connection method. With the connectors at both ends of the water pipe 36, it is easy to disassemble, repair, and replace. It can be flexibly combined and arranged according to the operating conditions, and has strong modular adaptability.

[0036] Example 2: Based on Example 1 above, as follows Figures 1-2 As shown, a drive box 15 is fixedly installed on the left side wall of the U-shaped seat 1. One end of the drive box 15 is connected to a drive pipe 14, and the other end of the drive box 15 is connected to a connecting pipe 2. The water inlet pipe 16 rotates through the U-shaped seat 1 and is rotatably connected to the connecting pipe 2. A gear 1 3 is fixedly installed on the water inlet pipe 16. A rotating rod 17 is rotatably installed inside the drive box 15. A blade 18 is installed on the rotating rod 17. The rotating rod 17 rotatably passes through the left side wall of the U-shaped seat 1. A gear 2 13 is fixedly installed on the rotating rod 17. The gear 2 13 meshes with the gear 1 3. The diameter of the gear 2 13 is smaller than the diameter of the gear 1 3.

[0037] In this design, the rotating rod 17 can be driven to rotate by the impact of the fluid medium on the blade 18, without the need for any other conventional power drive structure. However, in order to avoid insufficient speed and driving force due to insufficient fluid power, a motor can be added to assist in driving the rotating rod 17 to ensure stable and reliable transmission and rotation. The working principle and beneficial effects of the above technical solution are as follows: The heat exchange medium flows into the drive box 15 through the drive pipe 14. The medium flow impacts the blades 18, causing the rotating rod 17 to rotate synchronously. The rotating rod 17 drives the gear 13 to rotate together, and the gear 13 drives the gear 3 to rotate. Since the diameter of the driving gear 13 is smaller than that of the driven gear 3, speed reduction and torque increase are achieved, reducing the rotational speed of the inlet pipe 16 and increasing the output torque. This smoothly drives the inlet pipe 16 and the phase change module to rotate slowly at low speed, using the kinetic energy of the medium fluid itself for drive, without the need for an additional motor power source. Powered by the impact of water flow on the blades 18, the purely mechanical fluid self-drive system can operate without an external motor. It features a simple and compact structure, low energy consumption, and low failure rate, making it suitable for long-term continuous operation. The low-speed rotation of the phase change module allows for more uniform circumferential heating and heat exchange among the phase change modules, effectively improving localized uneven heating and cooling. This further suppresses the sedimentation, agglomeration, and wall adhesion of the phase change material, thereby enhancing the stability of heat storage and release and the overall heat exchange efficiency.

[0038] Example 3: Based on Examples 1-2 above, as follows Figures 1-2 , Figures 8-9 As shown, a support block 12 is also fixedly installed on the U-shaped seat 1. A fixed box 8 is fixedly installed on the upper end of the support block 12. The right end of the fixed box 8 is fixedly connected to the U-shaped seat 1. The rotating rod 17 extends into the fixed box 8. A threaded part 19 is provided on the rotating rod 17. A follower block 47 is threadedly connected to the threaded part 19. A connecting block 48 is fixedly installed at the rear end of the follower block 47. A sliding groove is provided on the rear side wall of the fixed box 8. The connecting block 48 extends out of the fixed box 8 from the sliding groove and is slidably connected to the sliding groove. The vibration mechanism includes an arc-shaped vibration plate 5. The connecting block 48 is fixedly connected to the arc-shaped vibration plate 5.

[0039] Preferably, a plurality of sleeves 49 are uniformly fixed on the arc-shaped vibrating plate 5, a piston plate 50 is slidably disposed inside the sleeve 49, a piston rod 52 is fixedly disposed on the piston plate 50, the piston rod 52 extends slidably out of the sleeve 49, a spring 51 is sleeved on the piston rod 52, the spring 51 is fixedly connected to the piston plate 50 and the sleeve 49, and a striking head 53 is fixedly disposed at the other end of the piston rod 52; a plurality of rings 6 are fixedly disposed on the periphery of the fixed cylinder 4, and the striking head 53 cooperates with the rings 6.

[0040] The working principle and beneficial effects of the above technical solution are as follows: the blade 18 drives the rotating rod 17 to rotate synchronously, the threaded part 19 on the rotating rod 17 and the follower block 47 form a screw nut transmission, which converts the rotational motion of the rotating rod 17 into the reciprocating linear motion of the follower block 47; the follower block 47 and the connecting block 48 slide along the slide groove of the fixed box 8, and drive the arc-shaped vibration plate 5 to move synchronously back and forth. During the movement of the arc-shaped vibrating plate 5, it drives each sleeve 49, piston rod 52 and striking head 53 to move together, so that the striking head 53 periodically abuts against the ring 6; after the striking head 53 passes the ring 6, the striking head 53 will strike the outer circumference of the fixed cylinder 4; under the elastic buffering and reset action of the spring 51 and piston plate 50, continuous elastic striking vibration is formed, and the vibration is transmitted to each phase change module 31 inside the fixed cylinder 4 as a whole.

[0041] The rotary motion is converted into linear reciprocating motion by using a lead screw and nut drive. The ring 6 is elastically struck by the striking head 53, which causes the fixed cylinder 4 to generate uniform low-frequency vibration. This effectively breaks the static state of the phase change material inside the phase change module, suppresses the sedimentation and stratification, bottom agglomeration, and inner wall adhesion phenomena that occur during the hot and cold cycle, reduces heat exchange resistance, and avoids the decay of heat exchange efficiency.

[0042] Example 4: Based on Example 3 above, as follows Figures 1-2 , Figure 8 As shown, a support column 10 is fixedly installed on the U-shaped base 1, and an air box 9 is fixedly installed on the support column 10. The air box 9 is fixedly connected to the right side wall of the U-shaped base 1. A push plate 23 is slidably installed inside the air box 9. A push rod 21 is fixedly installed at one end of the push plate 23. The push rod 21 slidably extends out of the air box 9, and an L-shaped rod 20 is fixedly installed at the other end of the push rod 21. A second sliding groove is opened on the front side wall of the fixed box 8. The L-shaped rod 20 extends from the second sliding groove into the fixed box 8. The L-shaped rod 20 is slidably connected to the second sliding groove, and the L-shaped rod 20 is fixedly connected to the follower block 47.

[0043] Preferably, a second spring 22 is sleeved on the air push rod 21, and the two ends of the second spring 22 are fixedly connected to the air box 9 and the air push plate 23; an air inlet pipe 24 and an air outlet pipe 25 are connected through the air box 9, and the air inlet pipe 24 and the air outlet pipe 25 are connected through the fixed cylinder 4, and both the air inlet pipe 24 and the air outlet pipe 25 are equipped with one-way valves.

[0044] The working principle and beneficial effects of the above technical solution are as follows: During the linear reciprocating sliding process, the follower block 47 synchronously drives the L-shaped rod 20 to slide along the second slide groove. The L-shaped rod 20 pulls the push rod 21 and the push plate 23 to perform reciprocating push-pull motion inside the air box 9. When the push plate 23 moves back and forth, it cooperates with the elastic reset action of the second spring 22 to form a periodic inhalation and blowing action inside the air box 9.

[0045] Under the action of the one-way valve, the air in the air box 9 is forced into the fixed cylinder 4 through the air inlet pipe 24, and then returns to the air box 9 through the air outlet pipe 25, thereby disturbing the air inside the fixed cylinder 4. With the help of the airflow disturbance combined with the external mechanical impact vibration, convective disturbance is formed on the air around the phase change module inside the fixed cylinder 4, which further assists the phase change material to exchange heat evenly.

[0046] The periodic airflow circulation formed by the air box 9, the air pusher plate 23, and the one-way valve can promote air convection inside the fixed cylinder, balance the internal temperature field, reduce local temperature differences, and help improve the overall heat exchange uniformity. The airflow disturbance and the external mechanical knocking vibration work together to further suppress the sedimentation, stratification, agglomeration and wall adhesion of the phase change material, slow down the rate of increase of heat exchange thermal resistance, and effectively ensure the long-term heat storage and release efficiency and operational stability of the device.

[0047] Example 5: Based on Example 4 above, as follows Figures 1-4 As shown, a connecting cylinder 32 is fixedly installed through the water inlet pipe 16. An L-shaped pipe 29 is symmetrically connected through the connecting cylinder 32. A rotating pipe 28 is rotatably connected through the L-shaped pipe 29. The rotating pipe 28 is detachably and fixedly connected to the phase change module. A rotating pipe 33 is detachably and fixedly connected to the other end of the phase change module. An L-shaped pipe 34 is rotatably connected through the rotating pipe 33. A connecting cylinder 35 is fixedly connected through the other end of the two L-shaped pipes 34. A water outlet pipe 7 is fixedly connected through the connecting cylinder 35.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the heat exchange medium flows into the connecting cylinder 32 through the inlet pipe 16, and after being diverted by the L-shaped pipes 29 arranged symmetrically on both sides, it enters the rotating pipe 28 and then enters the phase change module to complete the heat exchange; the heat exchanged medium flows into the connecting cylinder 35 through the rotating pipe 33 and the L-shaped pipe 34 in sequence, and finally flows out through the outlet pipe 7.

[0049] Rotary tube 28 and L-shaped tube 29, as well as rotary tube 33 and L-shaped tube 34, can all rotate relative to each other. When the phase change module rotates synchronously with the water inlet pipe 16, both rotary tube 28 and rotary tube 33 can rotate, thereby driving the phase change module to rotate, further improving the overall heat exchange efficiency and heat storage and release balance. The symmetrical pipeline layout with split flow ensures uniform medium distribution and can simultaneously exchange heat on multiple phase change modules, making it more practical.

[0050] Example 6: Based on Example 5 above, as follows Figures 3-7 As shown, a hollow disc 37 is fixedly installed on the inner wall of the fixed cylinder 4. A circular groove 42 is opened on the left side of the hollow disc 37, and a circular plate 41 is installed at the circular groove 42. The circular plate 41 is fixedly connected to two L-shaped tubes 29. An opening is provided on the right side of the hollow disc 37, through which a rotating tube 28 passes. A connecting rod 26 is fixedly installed on the connecting cylinder 32, and the connecting rod 26 passes through the circular plate 41. A rotating disc 27 is rotatably installed at the other end of the connecting rod 26. A meshing wheel 30 is fixedly installed on the rotating tube 28. A mating belt is fixedly installed on the inner wall of the hollow disc 37, and the meshing wheel 30 mates with the mating belt. A toothed ring is fixedly installed on the periphery of the rotating disc 27, and the toothed ring meshes with the meshing wheel 30.

[0051] Preferably, a circular ring plate 39 is fixedly provided on the circular plate 41, and a notch 40 is provided on the circular ring plate 39. One side of the notch 40 is sloped. A striking component is provided on the side of the rotating disk 27 near the circular plate 41. The striking component includes a second striking head 46, which cooperates with the circular ring plate 39.

[0052] Preferably, the striking assembly further includes a sleeve 38, which is fixedly mounted on the rotating disk 27. A piston plate 43 is disposed inside the sleeve 38, and a piston rod 45 is fixedly mounted on the piston plate 43. The piston rod 45 slides out of the sleeve 38, and a spring 44 is sleeved on the piston rod 45. The spring 44 is fixedly connected to the piston plate 43 and the sleeve 38. A striking head 46 is fixedly mounted on the other end of the piston rod 45.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When the phase change module rotates around the axis as a whole with the water inlet pipe 16, it drives the rotating pipe 28 and the meshing wheel 30 to revolve synchronously; the meshing wheel 30 moves along the mating strip on the inner wall of the hollow disc 37, and generates its own rotation while revolving (the phase change module itself will also generate its own rotation); the meshing wheel 30 drives the rotating disc 27 to rotate through the gear ring drive, the connecting rod 26 and the circular plate 41 revolve in the same direction and at the same speed with the whole pipeline, while the rotating disc 27 is subjected to planetary meshing, and rotates in the opposite direction to the connecting rod 26 and the circular plate 41, forming a speed difference.

[0054] The rotation of the meshing wheel 30 further amplifies the relative rotation speed of the rotating disk 27, significantly increasing the frequency of the striking head 46 traversing the annular plate 39. The rotating disk 27 drives the sleeve 38, spring 44, piston rod 45, and striking head 46 to perform circular motion synchronously. The notch 40 on the annular plate 39 is designed as a sloping structure, with the slope mainly used for guiding and transitioning, facilitating the smooth ascent of the striking head 46 and its successful contact with the annular plate 39, as it continues to rotate with the rotating disk 27. When the striking head 46 moves to the position of the notch 40 along the rotation trajectory, it loses the support and limit of the annular plate 39 and is quickly ejected under the elastic reset action of the spring 44, forming a precise elastic striking action. This cycle repeats continuously and regularly, creating stable mechanical micro-disturbances and airflow convection inside the fixed cylinder 4.

[0055] The phase change module has both overall revolution and self-rotation, which allows the internal phase change material to roll and reposition in all directions, avoiding static accumulation from the root. In addition, the impact of the second striking head 46 makes the internal disturbance stronger and more uniform. The slope of the ring plate 39 plays a smooth guiding transition role, ensuring the smooth climbing of the second striking head 46. The fixed point elastic striking is triggered only when it rotates to the position of the notch 40. Based on the external impact vibration and airflow disturbance of the aforementioned embodiments, a rotation mode of revolution and rotation of the phase change module is added, which is combined with the internal fixed-point elastic impact structure; there is external impact vibration, internal high-frequency disturbance, and the phase change module itself can also tumble and stir. The three work together to achieve all-round coordinated disturbance inside and outside.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
