[0003] Low-temperature phase-change cold storage and energy storage equipment uses the phase change characteristics of phase change materials at specific low temperatures to store cold energy to meet the cold energy needs of various aspects such as cold chain logistics and industrial refrigeration. Low-temperature phase-change cold storage and energy storage equipment usually contains a key component, the heat exchange tube, whose main function is to realize the heat exchange between the phase change material and the external cold source or the cooling system. Once the heat exchange tube fails, it must be replaced or repaired in time to ensure the normal operation of the equipment.

[0004] However, existing low-temperature phase-change cold storage energy storage equipment has obvious defects in its structural design. The heat exchange tubes are often tightly installed in the complex structure inside the equipment and are surrounded by a large amount of insulation materials and other auxiliary components. Therefore, when disassembling and maintaining the heat exchange tubes, maintenance personnel first need to painstakingly remove the outer insulation structure of the equipment. This process is time-consuming and labor-intensive, greatly increasing the workload of operators. In addition, repeated disassembly and installation can easily damage the insulation material, affecting the subsequent insulation performance of the equipment, thereby greatly weakening the energy storage effect of the equipment.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 - Figure 4The utility model provides an embodiment: a low-temperature phase-change cold storage energy storage device, including a device body 1 and a refrigeration device connecting pipe 19, a heat exchange tube 2 is arranged inside the device body 1, the outer wall of the heat exchange tube 2 is fixedly connected to the guide tube 6, the outer wall of the heat exchange tube 2 is fixedly connected to the connecting block 15, the lower surface of the connecting block 15 is fixedly connected to the slide bar 5, a slide groove 4 is opened inside the device body 1, the inner wall of the slide groove 4 is slidably connected to the outer wall of the slide bar 5, one side of the outer wall of the slide bar 5 is fixedly connected to the connecting plate 3, a clamping component is arranged inside the slide bar 5, the clamping component is used to fix the slide bar 5, so that the heat exchange tube 2 can be disassembled More simply, the clamping assembly includes a moving block 21, the outer wall of the moving block 21 is slidably connected to the inside of the slide bar 5, the moving block 21 is fixedly connected to a spring 9, one end of the spring 9 is fixedly connected to a clamping block 8, and one side of the outer wall of the moving block 21 is fixedly connected to a connecting rod 11. When the heat exchange tube 2 needs to be disassembled and maintained, the connecting rod 11 can be pulled outward first, and then the connecting rod 11 will drive the moving block 21 on its outside to move. When the moving block 21 moves, the clamping block 8 inside the moving block 21 will be squeezed by the clamping groove inside the device body 1, so that the clamping block 8 is moved into the moving block 21. When the slider 5 is moved, the spring 1 9 will be squeezed and contracted until the block 8 completely enters the moving block 21. At this time, the moving block 21 will also be pulled to the rightmost end of the slider 5, thereby releasing the lock on the slider 5. At this time, the heat exchange tube 2 can be pulled out, and the outer wall of the connecting rod 11 is provided with an elastic component, which is used to assist the moving block 21 to move. The elastic component includes a spring 2 10, which is sleeved on the outer wall of the connecting rod 11. The connecting rod 11 is fixedly connected to a pulling member 12. The handle 7 on one side of the outer wall of the connecting plate 3 can be pulled to drive the connecting plate 3 on the outer wall of the slider 5 to move. The slide bar 5 moves so that the slide bar 5 slides in the slide groove 4 on the inner wall of the equipment body 1, thereby driving the heat exchange tube 2 to move, so that the heat exchange tube 2 can be removed from the equipment body 1, thereby realizing the disassembly and maintenance of the heat exchange tube 2. The heat exchange tube 2 that has been maintained can then be inserted into the slide groove 4 through the slide bar 5. When the slide bar 5 is fully inserted into the equipment body 1, the connecting rod 11 is released. At this time, under the elastic action of the spring 10, the moving block 21 is pushed to move until the moving block 21 moves to the lower surface of the card slot, and then the elastic action of the spring 9 is restored, thereby realizing the card connection and fixation of the heat exchange tube 2.

[0026] Reference Figure 3 - Figure 5, the outer wall of the heat exchange tube 2 is fixedly connected with a connecting cylinder 13, a groove 20 is provided inside the refrigeration equipment connecting pipe 19, a docking groove 16 is provided inside the connecting cylinder 13, the inner wall of the docking groove 16 is slidably connected to the outer wall of the refrigeration equipment connecting pipe 19, and a spring three 17 is fixedly connected to the inside of the connecting cylinder 13. One end of the spring three 17 is fixedly connected to a card bead 18, and the card bead 18 is used to engage with the groove 20. When the connecting cylinder 13 on the outer wall of the heat exchange tube 2 needs to be sealed and docked with the refrigeration equipment connecting pipe 19, the refrigeration equipment connecting pipe 19 can be inserted along the docking groove 16 first. At this time, the spring three 17 fixedly connected inside the connecting cylinder 13 is in a compressed state. When the refrigeration equipment connecting pipe 19 is fully inserted into the docking groove 16, the connecting cylinder 13 is in a compressed state. The card bead 18 inside the connecting tube 13 is stuck in the groove 20 opened inside the connecting pipe 19 of the refrigeration equipment under the elastic force of the spring three 17, and the elastic force provided by the spring three 17 ensures that the card bead 18 is stably stuck in the groove 20, thereby realizing the fixation of the connecting tube 13 and the connecting pipe 19 of the refrigeration equipment in the circumferential direction, preventing the two from relative rotation or displacement, and achieving the effect of preliminary sealing. The inner wall of the heat exchange tube 2 is fixedly connected with a blocking block 14. When the card bead 18 is stuck in the groove 20, the connecting tube 13 and the connecting pipe 19 of the refrigeration equipment are tightly fitted under the elastic force of the spring three 17. This tight fit makes the contact surface between the two form a seal, ensuring the sealing and stability of the cold transfer during the operation of the equipment.

[0027] Working principle: When the device needs to store cold, the device body 1 is sealed and connected to the external refrigeration system. The low-temperature refrigerant treated by the refrigeration system flows along the pipeline into the external space of the heat exchange tube 2 inside the device under the action of pressure difference. As heat is continuously transferred to the refrigerant through the heat exchange tube 2, the temperature of the phase change material in the heat exchange tube 2 gradually decreases. When the temperature of the phase change material reaches its specific phase change temperature, the phase change material begins to undergo phase change, such as from liquid to solid. During this phase change process, the phase change material will absorb a large amount of latent heat, thereby realizing the storage of cold.

[0028] When the heat exchange tube 2 needs to be disassembled and maintained, the connecting rod 11 can be pulled outward first, and then the connecting rod 11 will drive the moving block 21 on its outside to move. When the moving block 21 moves, the card block 8 inside the moving block 21 will be squeezed by the card slot inside the device body 1, so that the card block 8 moves into the moving block 21. At this time, the spring 1 9 will also be squeezed and contracted until the card block 8 completely enters the moving block 21. At this time, the moving block 21 will also be pulled to the rightmost end of the slide bar 5, thereby releasing the lock on the slide bar 5. At this time, the heat exchange tube 2 can be pulled out, and the slide bar 5 can be driven by pulling the handle 7 on the outer wall of the connecting plate 3. The connecting plate 3 on one side of the outer wall of the bar 5 moves, so that the slide bar 5 slides in the slide groove 4 on the inner wall of the equipment body 1, thereby driving the heat exchange tube 2 to move, so that the heat exchange tube 2 can be removed from the equipment body 1, thereby realizing the disassembly and maintenance of the heat exchange tube 2. The heat exchange tube 2 after maintenance can then be inserted into the slide groove 4 through the slide bar 5. When the slide bar 5 is fully inserted into the equipment body 1, the connecting rod 11 is released. At this time, under the elastic action of the spring 2 10, the moving block 21 is pushed to move until the moving block 21 moves to the lower surface of the card slot, and then the elastic action of the spring 1 9 is restored, thereby realizing the card connection and fixation of the heat exchange tube 2;

[0029] When it is necessary to seal the connecting tube 13 on the outer wall of the heat exchange tube 2 with the refrigeration equipment connecting tube 19, the refrigeration equipment connecting tube 19 can be inserted into the docking groove 16 first. At this time, the spring three 17 fixedly connected inside the connecting tube 13 is in a compressed state. When the refrigeration equipment connecting tube 19 is fully inserted into the docking groove 16, the card bead 18 inside the connecting tube 13 is stuck into the groove 20 opened inside the refrigeration equipment connecting tube 19 under the elastic force of the spring three 17, and the elastic force provided by the spring three 17 ensures that the card bead 18 is stably stuck in the groove 20, thereby achieving the fixation of the connecting tube 13 and the refrigeration equipment connecting tube 19 in the circumferential direction, preventing the two from relative rotation or displacement, and achieving the effect of preliminary sealing. After the card bead 18 is stuck in the groove 20, the connecting tube 13 and the refrigeration equipment connecting tube 19 are tightly fitted under the elastic force of the spring three 17. This tight fit makes the contact surface between the two form a seal, ensuring the sealing and stability of the cold transfer during operation of the equipment.
