Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically, to a phase change heat exchanger. Background Technology

[0002] In modern industrial and civilian applications, phase change heat exchangers are crucial heat energy conversion devices, and their performance directly impacts energy utilization efficiency and economy. Traditional phase change heat exchangers transfer energy by storing heat from hot water in a phase change material and then relying on cold water flowing in the opposite direction through the heat exchanger to remove the heat. However, this seemingly simple and direct heat exchange process actually faces numerous technical bottlenecks and performance limitations.

[0003] First, the structure of traditional heat exchangers is too simple and primitive, and their internal design lacks specificity and optimization. Traditional heat exchangers usually adopt straight tubes or simple tube bundle structures, with limited heat exchange area and low heat exchange efficiency. In practical applications, there is significant thermal resistance in the heat transfer process, which leads to a significant reduction in energy conversion efficiency. This inefficient heat exchange not only increases energy consumption, but also greatly reduces the overall performance of the equipment, resulting in significant economic losses for industrial production and energy utilization. Low heat exchange efficiency means that more thermal energy is wasted, and at the same time, the equipment needs to consume more energy to maintain normal operation, forming a vicious cycle of energy utilization.

[0004] Secondly, the internal structure of the pipes in existing technologies is extremely simple, and the flow velocity of the water lacks a flexible adjustment mechanism. The pipe design of traditional heat exchangers often adopts a fixed cross-section and uniform flow velocity, which cannot be dynamically adjusted according to actual usage conditions. This rigid design causes the heat exchanger to fail to achieve optimal heat exchange performance under different operating conditions. For example, when operating at low load, excessively high water flow velocity will reduce heat exchange efficiency; while when operating at high load, insufficient water flow velocity will limit heat transfer. This inflexible flow velocity control mechanism severely restricts the adaptability of the heat exchanger, making it difficult for the equipment to meet the refined heat energy conversion needs of different scenarios.

[0005] In addition, some equipment has attempted to design some regulating devices to solve the problem of water flow velocity regulation. However, these devices generally suffer from technical defects such as simple structure and low stability. The anti-interference ability of such regulating mechanisms is extremely limited. In actual operation, the violent impact of water flow, equipment vibration and the influence of the external environment will cause the regulating device to produce small but continuous displacement and loosening. This seemingly insignificant structural change will actually have a significant impact on the precise control of water flow velocity. The instability of the regulating mechanism means that the preset water flow velocity will inevitably deviate, thereby affecting the overall performance and heat energy conversion efficiency of the heat exchanger.

[0017] 1. The heat exchange device, through the special structural design of the heat exchange tubes and the installation of heat sinks, effectively increases the heat exchange area and improves the heat transfer efficiency, ensuring uniform heat exchange with the phase change material.

[0030] Please see Figure 1-6A phase change heat exchanger includes a heat exchange tube 1. A heat exchange device is disposed on the outside of the heat exchange tube 1. The heat exchange device includes an inlet pipe 2, an outlet pipe 3, and heat exchange plates 4. The inlet pipe 2 is connected to one end of the heat exchange tube 1, and the outlet pipe 3 is connected to the other end of the heat exchange tube 1. Multiple heat exchange plates 4 are installed on the outside of the heat exchange tube 1. A speed regulating device is connected to one end of both the inlet pipe 2 and the outlet pipe 3. The speed regulating device includes a conveying pipe 5, a mating sleeve 6, a connecting pipe 7, a mating rod 8, a control sleeve 9, a connecting frame 10, a sliding block 11, a sliding rod 12, and an adjusting plate 13. The mating sleeve 6 is threadedly fitted onto the outside of the mating rod 8. One conveying pipe 5 is connected to the outlet pipe 3, and one connecting pipe 7 is connected to the inlet pipe 2. The mating rod 8 is connected to one side of the sliding block 11. The two sides of the control sleeve 9 are rotatably connected to the conveying pipe 5 and the connecting pipe 7, respectively. The connecting frame 10 is fixedly installed inside the conveying pipe 5. The sliding rod 12 is slidably connected to the connecting frame 10. Multiple adjusting plates 13 are movably connected to the inner wall of the conveying pipe 5. A fixing mechanism is provided on the outer side of the conveying pipe 5. The fixing mechanism includes a movable plate 14, a movable groove 15, a fixed sleeve 16, a movable rod 17, a connecting spring 18, a fixed rod 19, and a fixed groove 20. The movable plate 14 is rotatably sleeved on the outer side of the conveying pipe 5. The movable groove 15 is opened on the movable plate 14. The fixed sleeve 16 is slidably sleeved on the outer side of the conveying pipe 5. The movable rod 17 is fixedly connected to one side of the fixed sleeve 16. Multiple fixed rods 19 are slidably installed on the side wall of the control sleeve 9. One end of the fixed rod 19 is connected to the outer wall of the control sleeve 9 through the connecting spring 18. The other end of the fixed rod 19 is inserted into the fixed groove 20. Multiple fixed grooves 20 are opened on the outer side of the conveying pipe 5.

[0031] An adapter frame 21 is connected to the outer side of the sleeve 6, and an adapter block 22 is fixedly provided on the outer side of the adapter frame 21. An adapter groove 23 is correspondingly opened in the conveying pipe 5, and the adapter block 22 is slidably disposed in the adapter groove 23.

[0032] The inner side of the control sleeve 9 is connected to a mating bracket 24, and the mating sleeve 6 is fixedly connected to the inner wall of the control sleeve 9 through the mating bracket 24.

[0033] A reset spring 25 is connected to one side of the adjusting plate 13, and the other end of the reset spring 25 is connected to the inner wall of the conveying pipe 5.

[0034] A movable spring 26 is movably sleeved on the outer side of the movable rod 17. One end of the movable spring 26 is connected to the fixed sleeve 16, and the other end of the movable spring 26 is in contact with the movable plate 14.

[0035] Both the control sleeve 9 and the fixed sleeve 16 are connected to rubber strips 27 on their outer sides.

[0036] In this embodiment, when the water flow speed needs to be adjusted, the movable plate 14 is first rotated, causing the movable plate 14 to move the movable groove 15. When the movable groove 15 moves to a position concentric with the movable rod 17, the fixed sleeve 16 is pushed, which in turn moves the movable rod 17. The movable rod 17 then passes through the movable groove 15. At the same time, the fixed sleeve 16 and the movable plate 14 cooperate to compress the movable spring 26 sleeved on the outside of the movable rod 17. When the movable spring 26 is compressed to its limit, the outer side of the fixed rod 19 loses the restriction of the inner wall of the fixed sleeve 16. Then, the control sleeve 9 is rotated, which causes the multiple fixed rods 19 slidably disposed on the side wall to rotate. Then, the side wall of the fixing groove 20 presses against one end of the fixing rod 19. Due to the rounded corner design of the end of the fixing rod 19 and the edge of the fixing groove 20, one end of the fixing rod 19 will slide out of the fixing groove 20, and the other end of the fixing rod 19 will drive the connecting spring 18 to stretch. At the same time, the operating sleeve 9 will drive the mating sleeve 6 to rotate through the mating frame 24 set on the inner side. Since the mating sleeve 6 is threaded and movably sleeved on the outside of the mating rod 8, and the adapter block 22 and the adapter groove 23 cooperate to limit the adapter frame 21 and the mating rod 8, preventing the adapter frame 21 and the mating rod 8 from rotating, the mating rod 8 will then drive the adapter frame 21 and the adapter block 22 along the adapter groove 20. 3. Sliding is performed, and simultaneously, the lever 8 drives the sliding block 11 connected at one end to move. Then, the sliding block 11 pushes the outer sliding rod 12 to slide along the connecting frame 10. Then, the other end of the sliding rod 12 pushes the adjusting plate 13 to spread outward. At the same time, the adjusting plate 13 squeezes the reset spring 25 connected on the other side, causing a change in the cross-sectional area of ​​the corresponding position in the delivery pipe 5, thereby changing the water flow area and thus changing the water flow speed. After appropriate adjustment, the rotation of the control sleeve 9 is stopped, and the connecting spring 18 drives the fixing rod 19 to reset. Then, the other end of the fixing rod 19 is inserted into the corresponding fixing groove 20. After releasing the fixed sleeve 16, the movable spring 26 resets and pushes the fixed sleeve 16 back to its original position. Then, the fixed sleeve 16 drives the movable rod 17 to slide back to its original position. After the movable spring 26 has fully reset, the movable plate 14 continues to rotate, causing the movable plate 14 to move the movable groove 15 to a position that does not correspond to the movable rod 17. At this time, the movable rod 17 provides stable support for the fixed sleeve 16, preventing the fixed sleeve 16 from sliding. Then, the inner wall of the fixed sleeve 16 limits the outer end of the fixed rod 19, preventing the fixed rod 19 from moving. Then, the fixed rod 19 and the fixed groove 20 cooperate to limit the control sleeve 9, preventing the control sleeve 9 from rotating, thereby ensuring the stability after the flow rate is adjusted.

[0037] Please see Figures 1-4 As a further implementation of the overall equipment: a mounting plate 28 is provided on one side of the heat exchange tube 1, a sealing box 29 is detachably provided on the outside of the heat exchange tube 1, and a sealing cover 30 is detachably provided on one side of the sealing box 29.

[0038] A sealing strip 31 is fixedly provided on one side of the sealing cover 30, and a corresponding sealing groove 32 is provided on the inner side of the sealing box 29. The sealing groove 32 is adapted to the sealing strip 31.

[0039] More specifically, when the device is needed, hot water is delivered to the heat exchange tube 1 through the inlet pipe 2 via an external conveying device. The special structural design of the heat exchange tube 1 ensures uniform heat exchange between the phase change material and the sealed box 29. The multiple heat sinks effectively increase the heat exchange area, thereby improving the heat exchange efficiency. The sealing strip 31 on one side of the sealing cover 30 cooperates with the sealing groove 32 in the sealed box 29 to provide a relatively sealed environment. The sealing cover 30 and the sealed box 29 are made of heat-insulating material to reduce heat loss and thus reduce energy consumption. After the heat exchange is completed, the water flows out through the blow pipe. When it is necessary to release and transfer energy, the delivered hot water is replaced with cold water, so that the cold water can carry away the heat stored in the phase change material.

[0040] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the water flow speed, first rotate the movable plate 14, causing the movable plate 14 to move the movable groove 15. When the movable groove 15 moves to a position concentric with the movable rod 17, push the fixed sleeve 16. The fixed sleeve 16 will then move the movable rod 17, which will then pass through the movable groove 15. At the same time, the fixed sleeve 16 and the movable plate 14 will cooperate to compress the movable spring 26 sleeved on the outside of the movable rod 17. When the movable spring 26 is compressed to its limit, the outer side of the fixed rod 19 loses the limit of the inner wall of the fixed sleeve 16. Then rotate the control sleeve 9, which will drive multiple fixed springs slidably set on the side wall. The rod 19 rotates, and then the side wall of the fixing groove 20 presses against one end of the fixing rod 19. Due to the rounded corner design at the end of the fixing rod 19 and the edge of the fixing groove 20, one end of the fixing rod 19 slides out of the fixing groove 20, and the other end of the fixing rod 19 drives the connecting spring 18 to stretch. At the same time, the operating sleeve 9 drives the mating sleeve 6 to rotate through the mating frame 24 set on the inner side. Since the mating sleeve 6 is threadedly fitted onto the outside of the mating rod 8, and the adapter block 22 and the adapter groove 23 cooperate to limit the adapter frame 21 and the mating rod 8, preventing the adapter frame 21 and the mating rod 8 from rotating, the mating rod 8 then drives the adapter frame 21 and the adapter block 22 along... The device slides along the adapter groove 23, while the connecting rod 8 moves the sliding block 11 connected to one end. The sliding block 11 then pushes the outer sliding rod 12 to slide along the connecting frame 10. The other end of the sliding rod 12 pushes the adjusting plate 13 to spread outward, while the adjusting plate 13 compresses the return spring 25 connected to the other side, causing a change in the cross-sectional area of ​​the corresponding position in the delivery pipe 5. This changes the water flow area and thus the water flow speed. After adjustment, the control sleeve 9 is stopped from rotating, and the connecting spring 18 drives the fixing rod 19 to reset. Then, the other end of the fixing rod 19 is inserted into the corresponding fixing groove 20. Then, the fixed sleeve 16 is released, and the movable spring 26 resets, pushing the fixed sleeve 16 to reset. Then, the fixed sleeve 16 will drive the movable rod 17 to slide and reset. After the movable spring 26 is fully reset, the movable plate 14 continues to rotate, so that the movable plate 14 drives the movable groove 15 to move to a position that does not correspond to the movable rod 17. At this time, the movable rod 17 forms a stable support for the fixed sleeve 16, preventing the fixed sleeve 16 from sliding. Then, the inner wall of the fixed sleeve 16 limits the outer end of the fixed rod 19, so that the fixed rod 19 will not move. Then, the fixed rod 19 and the fixed groove 20 cooperate to limit the control sleeve 9, preventing the control sleeve 9 from rotating, thereby ensuring the stability after the flow rate is adjusted.

[0041] When the device is needed, hot water is delivered to the heat exchange tube 1 through the inlet pipe 2 via an external conveying device. The special structural design of the heat exchange tube 1 ensures uniform heat exchange between the phase change material and the sealed box 29. The multiple heat sinks effectively increase the heat exchange area, thereby improving the heat exchange efficiency. The sealing strip 31 on one side of the sealing cover 30 cooperates with the sealing groove 32 in the sealed box 29 to provide a relatively sealed environment. The sealing cover 30 and the sealed box 29 are made of heat insulation material to reduce heat loss and thus reduce energy consumption. After the heat exchange is completed, the water flows out through the blow pipe. When it is necessary to release and transfer energy, the delivered hot water is replaced with cold water, so that the cold water can carry away the heat stored in the phase change material.

For all the fixed connections mentioned above, welding is preferred.
