Description

Technical Field

[0001] This utility model belongs to the field of phase change energy storage technology, specifically a high-efficiency integrated phase change energy storage device. Background Technology

[0002] Phase change energy storage is a technology that utilizes the absorption or release of a large amount of latent heat during the phase change process of a substance to achieve energy storage and release. Its core principle is to use the phase change characteristics of phase change materials (PCMs) to store heat or cold when there is an energy surplus and release it when there is a shortage, so as to balance energy supply and demand.

[0003] Traditional phase change energy storage devices have a basically fixed shell volume, which makes it difficult to adapt to the volume changes of phase change materials during solid-liquid or solid-gas transitions. Long-term use can easily lead to shell deformation, sealing failure, or even cracking and damage to the device due to repeated expansion and contraction of the material, affecting its service life and safety. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a highly efficient integrated phase change energy storage device, which solves the problem that the shell volume of traditional phase change energy storage devices is basically fixed, making it difficult to adapt to the volume changes of phase change materials during solid-liquid or solid-gas transformation. Long-term use is prone to shell deformation and cracking damage due to repeated expansion and contraction of materials, affecting service life and safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency integrated phase change energy storage device, comprising a lower shell and an upper shell, wherein multiple support legs are connected to the lower shell, connecting pipes are connected to both sides of the lower shell, multiple limiting rods are connected to the wall of the lower shell, mounting plates are connected to both the lower shell and the upper shell, a hollow rod is fixedly mounted on the upper shell through the mounting plate, a connecting plate is connected to the upper shell, and multiple heat exchange pipes are inserted and installed inside the connecting plate; Multiple connecting blocks are connected to the upper shell wall. Fixing components are connected to the upper two sides of the upper shell. Fastening bolts are threaded onto the fixing components. A fixing plate is installed on the upper shell through the fastening bolts. A fixing head is connected to one end of the heat exchange tube. An annular groove is opened on the fixing head. A motor is fixedly installed on the hollow rod. A screw is connected to the output shaft of the motor. A movable rod is threaded onto the screw.

[0006] As a further embodiment of this utility model: a sealing plate is connected to the lower part of the upper shell, and the lower part of the upper shell and the sealing plate form an L-shaped structure. The sealing plate is in close contact with the inner wall of the lower shell, and a rubber sealing gasket is connected to the wall at the contact point.

[0007] As a further embodiment of this utility model: a pull rod is connected to the fixing plate, threaded holes are opened on both sides of the upper part of the fixing plate, and multiple limiting grooves are opened on the fixing plate.

[0008] As a further embodiment of this utility model: the fastening bolt is threadedly connected to the threaded hole, the fixing head is disposed in the limiting groove, and the wall of the annular groove is in contact with the wall of the limiting groove.

[0009] As a further embodiment of this utility model: one end of the limiting rod passes through the connecting block and is slidably connected to the connecting block; a spring is sleeved on the limiting rod; one end of the spring is connected to the top of the limiting rod; and the other end of the spring is connected to the connecting block.

[0010] As a further embodiment of this utility model: the movable rod slides inside the hollow rod and one end is connected to the mounting plate on the lower housing, and multiple fixing holes are provided below the support leg.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This highly efficient integrated phase change energy storage device, through the arrangement of a motor, hollow rod, screw, movable rod, connecting block, limit rod, spring, and sealing plate, allows the motor to rotate the screw, causing the movable rod, which is threaded into the screw, to slide out from the hollow rod, thereby lifting the upper shell. This causes the connecting block to slide upward along the limit rod and compress the spring, which in turn causes the sealing plate to move upward in a manner that is close to the inner wall of the lower shell. This changes the distance between the lower and upper shells, adjusts the volume formed by the lower and upper shells, and thus adapts to the volume change of the phase change material during the phase change process, preventing the material from being damaged by excessive pressure due to space constraints.

[0012] 2. This high-efficiency integrated phase change energy storage device, through the setting of heat exchange tubes, fixing heads, annular grooves, fixing plates, fastening bolts and threaded holes, allows the heat exchange tubes to be inserted from the connecting plate into the lower and upper housings. At this time, the fixing head will abut against the top of the connecting plate. Then, the fixing plate is inserted from one side of the upper housing, causing the wall of the limiting groove to fit into contact with the wall of the annular groove. Then, the fastening bolts are tightened to make the fastening bolts enter into the threaded holes, thereby fixing the fixing plate and limiting the multiple heat exchange tubes. The operation is simple and convenient for staff to disassemble and replace. Attached Figure Description

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figure 1-4 As shown, this utility model provides a technical solution: a high-efficiency integrated phase change energy storage device, including a lower shell 1 and an upper shell 2. Multiple support legs 3 are connected to the lower shell 1, and connecting pipes 4 are connected to both sides of the lower shell 1. Multiple limiting rods 5 are connected to the wall of the lower shell 1. One end of the limiting rod 5 passes through the connecting block 10 and is slidably connected to the connecting block 10. A spring 23 is sleeved on the limiting rod 5. One end of the spring 23 is connected to the top of the limiting rod 5, and the other end of the spring 23 is connected to the connecting block 10. The limiting rods 5 guide the movement of the upper shell 2, improve the stability of the movement, and prevent the upper shell 2 from tilting or shifting.

[0016] Mounting plates 6 are connected to both the lower housing 1 and the upper housing 2. A sealing plate 19 is connected to the lower part of the upper housing 2. The lower part of the upper housing 2 and the sealing plate 19 form an L-shaped structure. The sealing plate 19 is in close contact with the inner wall of the lower housing 1, and a rubber sealing gasket is connected to the wall at the contact point. Through the nested design of the L-shaped structure, the sealing plate 19 and the inner wall of the lower housing 1 form a double contact surface. With the elastic deformation of the rubber sealing gasket, the contact gap between the two can be tightly filled to achieve a seal.

[0017] The upper shell 2 is fixedly mounted with a hollow rod 7 via a mounting plate 6. A connecting plate 8 is connected to the upper shell 2, and multiple heat exchange tubes 9 are inserted into the connecting plate 8. Multiple connecting blocks 10 are connected to the wall of the upper shell 2. Fixing members 11 are connected to the upper sides of the upper shell 2, and fastening bolts 12 are threadedly connected to the fixing members 11. A fixing plate 13 is mounted on the upper shell 2 via the fastening bolts 12. A pull rod 20 is connected to the fixing plate 13. Threaded holes 21 are opened on the upper sides of the fixing plate 13, and multiple limiting grooves 22 are opened on the fixing plate 13. The fixing plate 13 can be stably fixed by the threaded connection between the fastening bolts 12 and the threaded holes 21, preventing the fixing plate 13 from sliding and falling.

[0018] One end of the heat exchange tube 9 is connected to a fixing head 14. The fixing head 14 has an annular groove 15. The fastening bolt 12 is threadedly connected to the threaded hole 21. The fixing head 14 is set in the limiting groove 22, and the groove wall of the annular groove 15 is in contact with the groove wall of the limiting groove 22. Through the contact between the groove wall of the annular groove 15 and the groove wall of the limiting groove 22, the fixing plate 13 can limit the heat exchange tube 9 and prevent the heat exchange tube 9 from moving.

[0019] A motor 16 is fixedly installed on the hollow rod 7. The output shaft of the motor 16 is connected to a screw 17. A movable rod 18 is threadedly installed on the screw 17. The movable rod 18 slides inside the hollow rod 7 and one end is connected to the mounting plate 6 on the lower housing 1. Multiple fixing holes 24 are provided below the support leg 3. By passing bolts through the fixing holes 24, the phase change energy storage device is fixed to the ground or base to prevent displacement due to vibration during operation and improve installation stability.

[0020] The working principle of this utility model is as follows: By inserting the heat exchange tubes 9 from the connecting plate 8 into the lower housing 1 and the upper housing 2, and then inserting the fixing plate 13 from one side of the upper housing 2, the wall of the limiting groove 22 is brought into contact with the wall of the annular groove 15. Then, by tightening the fastening bolt 12, the fastening bolt 12 is brought into the threaded hole 21, thereby fixing the fixing plate 13 and limiting the multiple heat exchange tubes 9. By starting the motor 16 and rotating the screw 17, the movable rod 18 slides out from the hollow rod 7, thereby lifting the upper housing 2. This causes the connecting block 10 to slide upward along the limiting rod 5 and compress the spring 23, thereby causing the sealing plate 19 to move upward in a way that is close to the inner wall of the lower housing 1. This changes the distance between the lower housing 1 and the upper housing 2, and adjusts the volume formed by the lower housing 1 and the upper housing 2 to adapt to the volume change of the phase change material during the phase change process.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
