Description

Technical Field

[0001] This invention relates to the field of phase change device technology, specifically to an automatic energy storage and heat release phase change device. Background Technology

[0002] Phase change materials (PCMs) have the ability to change their physical state within a certain temperature range. Taking solid-liquid phase change as an example, when heated to the melting temperature, a phase change occurs from solid to liquid. During the melting process, PCMs absorb and store a large amount of latent heat. When the PCMs cool, the stored heat dissipates into the environment within a certain temperature range, resulting in a reverse phase change from liquid to solid. The energy stored or released during these two phase change processes is called the latent heat of phase change. Existing energy storage bricks and phase change tubes are all made using PCMs, and the heat exchange efficiency and heating time of existing automatic energy storage and heat release phase change devices need to be improved.

[0003] Among them, announcement number CN106705727A discloses an automatic energy storage and heat release phase change device; including an inner cavity, multiple sets of partition plates disposed on the inner side of the inner cavity, a phase change layer cast between two adjacent sets of partition plates, an electric heating tube penetrating the partition plates and the phase change layer, a heat exchange channel disposed on the inner side of each set of partition plates, and a loop pipe connected to the input and output ends of the heat exchange channel; insulation cotton disposed on the outer side of the inner cavity, a shell disposed on the outer side of the insulation cotton, and a temperature controller electrically connected to the electric heating tube. However, this technical solution still has defects:

[0004] First, the outer casing of the device in this technical solution is inconvenient to open, which will cause great trouble for the replacement of phase change material and affect the replacement efficiency. Second, the direction of the heat exchange gas inlet and outlet pipes in this technical solution is fixed. Therefore, when connecting with pipes in different directions, additional swivel joints are required, which is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides an automatic energy storage and heat release phase change device, which has the following beneficial effects:

[0020] 1. This automatic energy storage and heat release phase change device uses a motor to drive the second spur gear to rotate, which in turn drives the gear ring to rotate, which in turn drives the two first spur gears to rotate, which in turn drives the transmission rods on both sides to rotate. Through the transmission of the first bevel gear and the second bevel gear, the threaded rods on both sides rotate, which drives the vertical plates on both sides to move. The vertical plates push multiple push rods to move vertically, which pushes the end caps on both sides away from the main body of the phase change device, thus opening both ends of the main body of the phase change device, making it convenient to replace the phase change material.

[0021] 2. This automatic energy storage and heat release phase change device allows the fourth spur gear to slide along the square rod, separating it from the third spur gear and releasing the restriction on the third spur gear. This allows the adjustment rod to be rotated, thus adjusting the direction of the connector and facilitating the connection of pipes in different directions. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Please see Figure 1-5 An automatic energy storage and heat release phase change device includes a phase change device body 1 and end caps 2. Two end caps 2 are abutted on both sides of the phase change device body 1. A sealing ring is fixedly installed on the inner wall of the end cap 2 to improve the sealing between the end cap 2 and the phase change device body 1. A heat exchange gas inlet pipe 3 and a heat exchange gas outlet pipe 4 are fixedly installed on the side of the two end caps away from the phase change device body 1, respectively. The heat exchange gas inlet pipe 3 and the heat exchange gas outlet pipe 4 are both equipped with filter screens to filter the gas entering the device. A corrugated pipe 5 is fixedly installed on one side of the heat exchange gas inlet pipe 3 and the heat exchange gas outlet pipe 4. A connector 6 is fixedly installed at the other end of the corrugated pipe 5. The corrugated pipe 5 is a metal corrugated pipe with good high temperature resistance. A fixing plate 23 is fixedly installed on one side of the end cap 2. An adjusting rod 21 is provided between the fixing plate 23 and the connector 6. First shaft pins 22 are fixedly sleeved on both ends of the adjusting rod 21. The fixing plate 23 and the connector 6 are rotatably connected at one end of the two first shaft pins 22.

[0030] Vertical plates 7 are provided between the two sides of the two end caps 2. Push rods 10 are provided between the two ends of the vertical plates 7 and the corresponding side of the end caps 2. The two ends of the push rods 10 are rotatably connected to U-shaped blocks 11 through the second shaft pins 12. Multiple U-shaped blocks 11 are fixedly connected to the corresponding vertical plates 7 and one end of the end caps 2 respectively. Fixed shells 8 are fixedly provided on both sides of the middle end of the phase change device body 1. Threaded rods 9 are rotatably provided on the inner side of the fixed shells 8. One end of the threaded rods 9 extends to the outer side of the fixed shells 8. The middle end of the vertical plates 7 is threadedly connected to the rod wall of the threaded rods 9. Anti-detachment blocks are fixedly sleeved on the ends of the threaded rods 9 on both sides away from the phase change device body 1 to prevent the vertical plates 7 from slipping off from one end of the threaded rods 9 as much as possible.

[0031] In order to enable the vertical plates 7 on both sides to push the corresponding push rods 10, the end caps 2 on both sides are opened, as shown in the figure. Figure 1-5 A drive mechanism for rotating the threaded rods 9 on both sides is provided on one side of the lower end of the phase change device body 1. The drive mechanism includes a transmission rod 18 and a gear ring 13. The transmission rod 18 is vertically arranged on the lower side of the fixed shell 8. One end of the transmission rod 18 extends into the interior of the fixed shell 8 and is rotatably connected to the inner wall of the fixed shell 8. A first bevel gear 17 is fixedly sleeved on one end of the threaded rod 9 inside the fixed shell 8. A second bevel gear 19 is fixedly sleeved on the upper end of the transmission rod 18. The first bevel gear 17 and the second bevel gear 19 are meshed and connected. A first spur gear is fixedly sleeved on the lower end of the transmission rod 18. 20. The gear ring 13 is meshed between the two first spur gears 20. The gear ring 13 is rotatably sleeved with the outer wall of the phase change device body 1. A support base 14 is fixedly installed on the lower front side of the phase change device body 1. A motor 15 is fixedly installed on the front side of the support base 14. The motor 15 is a geared motor that can provide a large and stable transmission force. The motor 15 is fixedly connected to the support base 14 through a support frame, making the connection between the motor 15 and the support base 14 more stable. A second spur gear 16 is fixedly sleeved on the output end of the motor 15. The second spur gear 16 meshes with the gear ring 13.

[0032] Motor 15 drives the second spur gear 16 to rotate, which in turn drives the gear ring 13 to rotate, which in turn drives the two first spur gears 20 to rotate, which in turn drives the transmission rods 18 on both sides to rotate. Through the transmission of the first bevel gear 17 and the second bevel gear 19, the threaded rods 9 on both sides rotate, which in turn drives the vertical plates 7 on both sides to move. The vertical plates 7 push the multiple push rods 10 to tend to be vertical, which can push the end caps 2 on both sides away from the phase change device body 1, thus opening both ends of the phase change device body 1, making it convenient to replace the phase change material.

[0033] In order to limit the position of the connector 6 after the angle has been adjusted, refer to... Figure 1-5A limiting mechanism for fixing the first shaft pin 22 is provided on one side of the fixing plate 23. The limiting mechanism includes a third spur gear 24 and a fourth spur gear 25. The third spur gear 24 is located on one side of the fixing plate 23 and is fixedly sleeved with the corresponding second shaft pin 12. The fourth spur gear 25 is meshed on one side of the third spur gear 24. A square hole is opened in the middle of the fourth spur gear 25. A square rod 26 is slidably arranged inside the square hole. One end of the square rod 26 is fixedly connected to the fixing plate 23. A retaining ring 27 is fixedly sleeved on the side of the square rod 26 away from the fixing plate 23. A spring 28 is movably sleeved on the rod wall of the square rod 26. The two ends of the spring 28 abut against the corresponding fourth spur gear 25 and the retaining ring 27, respectively.

[0034] Slide the fourth spur gear 25 along the square rod 26 to separate it from the third spur gear 24, thus releasing the restriction on the third spur gear 24. Then, rotate the adjusting rod 21 to adjust the direction of the connector 6, facilitating the connection of pipes in different directions. After adjustment, release the fourth spur gear 25, and the spring 28 pushes the fourth spur gear 25 back to its original position, causing it to mesh with the third spur gear 24 again. This restricts the third spur gear 24, preventing it from rotating, and thus restricts the adjusted connector 6.
