Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically an energy-saving volumetric heat exchanger based on a pillow-shaped plate and its usage method. Background Technology

[0002] A volumetric heat exchanger is a device that transfers heat by storing a heat medium. The shell can be cylindrical or rectangular. The former has strong pressure resistance and wide application, while the latter is suitable for narrow spaces and has the advantages of stable heat storage and easy maintenance. It is widely used in building heating, industrial production and other scenarios. It is an important device in continuous heating scenarios. Many scenarios (such as residential hot water and central heating) require a continuous and stable temperature output. However, the heat source (such as boilers and steam systems) may cause the heat medium supply to be unstable due to start-up and shutdown and load changes. Therefore, the volumetric heat exchanger can use stored heat to maintain the output temperature when the heat source fluctuates, avoiding the situation of sudden cooling and heating of water at the user end.

[0003] The operation of a volumetric heat exchanger is a precise and dynamic heat regulation process. It is based on the combined function of "storage + heat exchange" and achieves efficient and stable heat exchange through systematic parameter management and scenario adaptation strategies. The device uses a heat transfer medium to flow in the heat exchange tube bundle, and heat is conducted to the medium inside the shell through the metal tube wall. This method can effectively isolate the heat transfer medium from the heated medium and prevent contamination. However, because the heat transfer medium flows in the heat exchange tube bundle, the turbulence is low, the coil occupies a large space, and there is a lot of dead zone volume, resulting in low heat exchange efficiency. To address these issues, we designed an energy-saving volumetric heat exchanger based on a pillow plate. Summary of the Invention

[0004] The purpose of this invention is to address the problem of low heat exchange efficiency caused by low turbulence, large space occupied by coils, and large dead zone volume in the heat exchanger tube bundle. This invention provides an energy-saving volumetric heat exchanger based on a pillow plate and its usage method.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving volumetric heat exchanger based on a pillow plate, comprising: a shell, three pillow plates installed on the inner side of the shell, a second water storage shell fixedly connected to the inlet and outlet of each of the three pillow plates, a second connecting pipe installed at one end of each of the two second water storage shells, and the second connecting pipe extending through to the outside of the shell and connecting to an external water pipe, two sets of first water storage shells fixedly connected to the inner side of the shell, two first water storage shells in each set, and three third connecting pipes fixedly connected to one side of each first water storage shell, two heat medium cavities opened on the inner side of each pillow plate, the other end of each third connecting pipe communicating with the inner side of one of the heat medium cavities, a first connecting pipe installed on the other side of the first water storage shell, and the first connecting pipe extending through to the outside of the shell and connecting to an external water pipe, and a protrusion-concavity changing mechanism and a rotation mechanism provided on the inner side of the pillow plate.

[0006] As a further embodiment of the present invention: the protrusion and depression changing mechanism includes multiple sets of rectangular grooves on the inner side of the pillow-shaped plate, each set of rectangular grooves having multiple grooves, and each rectangular groove having two first sliding blocks, two second sliding blocks and one third sliding block on its inner side. The bottom of each first sliding block and each second sliding block is fitted with a second return spring on the inner side of the rectangular groove. The inner sides of the rectangular groove, the first sliding block and the second sliding block are all provided with first limiting grooves, and one end of the second sliding block, one end of the first sliding block and both ends of the third sliding block are fixedly connected to a limiting block. Each limiting block is slidably connected to the inner side of a first limiting groove.

[0007] As a further embodiment of the present invention: the protrusion and depression changing mechanism further includes a second limiting groove formed inside the first sliding block and the second sliding block, and the second limiting groove communicates with the first limiting groove. A rectangular block is fixedly connected to one side of each limiting block fixedly connected to the inside of the second sliding block and the third sliding block, and a driving mechanism is provided at the bottom of the rectangular block.

[0008] As a further embodiment of the present invention: the driving mechanism includes a connecting rod fixedly connected to the bottom of the third sliding block, and multiple sets of third limiting grooves are opened on the inner side of the rectangular groove. Each set of third limiting grooves is provided with multiple grooves, and each third limiting groove communicates with the inner side of the rectangular groove. A connecting plate is slidably connected to the inner side of each set of third limiting grooves, and the connecting rod is fixedly connected to the inner side of the connecting plate.

[0009] As a further embodiment of the present invention: the driving mechanism further includes a plurality of second mounting slots opened on the inner side of each of the pillow-shaped plates, a drive motor installed on the inner side of each of the second mounting slots, and the output end of the drive motor passes through the inner side of the rectangular slot and is fixedly connected to the connecting plate.

[0010] As a further embodiment of the present invention: the rotating mechanism includes a plurality of first mounting slots formed on the inner sides of the first sliding block, the second sliding block and the third sliding block, and one or two rotating rods are rotatably connected to the outer wall of each first mounting slot, and a rotating plate is fixedly connected to the outer wall of each rotating rod, and a first return spring is installed between the bottom of the rotating plate and the inner side of the first mounting slot.

[0011] As a further embodiment of the present invention: the rotating mechanism further includes through grooves formed inside the first sliding block, the second sliding block and the third sliding block, and the through grooves are respectively connected to the first mounting groove and the rectangular groove, and five drive rods are fixedly connected to the inner side of the rectangular groove.

[0012] As a further aspect of the present invention: the lengths of the five drive rods inside each rectangular groove increase sequentially from the center to both sides.

[0013] This invention also discloses a method for using an energy-saving volumetric heat exchanger based on a pillow-shaped plate, comprising the following steps:

[0014] S1. When heat exchange is required, the operator connects the first and second connecting pipes to the external pipes, and pours the heat medium and cold water into the inside of the first and second connecting pipes on the right side, respectively. At this time, the heat medium flows inside the heat medium cavity, and the heat is conducted to the cold water between the two pillow-shaped plates in the shell to heat the cold water. At the same time, the pillow-shaped plates are distributed in a zigzag pattern, which causes the cold water to change direction multiple times during the flow, forming a "bend" effect. This causes the cold water to generate eddies and turbulence at the bends, which destroys the boundary layer, reduces thermal resistance, and the zigzag path extends the flow distance of the fluid in the heat exchanger, giving the hot and cold fluids more time to exchange heat, thereby improving the heat exchange efficiency of the device.

[0015] S2. The drive motor is controlled by a PLC controller, which can control the intermittent start of the drive motor. When the operator pours hot medium and cold water into the inside of the first and second connecting pipes on the right, the PLC controller starts the drive motor. The output end of the drive motor drives the connecting plate to move up and down, thereby driving the connecting rod to move up and down, which in turn drives the third sliding block to move up and down. When the third sliding block moves downward, it drives the rectangular blocks on both sides of the third sliding block to move downward. When the rectangular blocks move downward to contact the bottom of the second limiting groove inside the second sliding block, they drive the second sliding block to move downward. And when the rectangular blocks on one side of the second sliding block move downward... When the third sliding block moves down to contact the bottom of the second limiting groove inside the first sliding block, the second sliding block causes the first sliding block to move downward, thus forming a stepped depression. When the third sliding block moves upward, the first and second sliding blocks are reset under the action of the first return spring, thus forming a stepped convex state. As the connecting plate moves up and down, it can cause the first, second and third sliding blocks to form a continuous change of stepped depression and convex, so that the fluid continuously contacts new heat exchange surfaces during flow, breaking the boundary layer thermal resistance. At the same time, when the water flows through the expansion structure, turbulence is generated due to the surface undulation, which improves the heat exchange efficiency of the device and thus improves the overall practicality of the device.

[0016] S3. When the second sliding block drives the first sliding block to move downward, the first, second, and third sliding blocks move downward simultaneously. When the five drive rods pass through the inner side of the through groove and contact the rotating plate, they push the six rotating plates to rotate under the action of the drive rods. This causes the rotating plates to flip at a certain angle, guiding the water flow from both sides of the rotating plates and allowing the water at the bottom of the rotating plates to pass through the flow groove. During the process of the rotating plates flipping to a certain angle and then resetting, the cold water forms a certain "push-pull" pulse on the inner side of the rectangular groove. This pulse, combined with the stepped depressions and protrusions during contraction, causes the fluid to produce a spiral flow similar to an "8," further increasing the turbulence of the water flow. At the same time, the two streams form a shear layer and vortex behind the rotating plate. When the vortex impacts the heat exchange surface, it destroys the boundary layer, reducing the thermal resistance and further improving the heat exchange efficiency of the device.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By setting up components such as pillow plates, the cold water changes direction multiple times during its flow, creating a "bend" effect. This causes eddies and turbulence to form at the bends, disrupting the boundary layer, reducing thermal resistance, and extending the flow distance of the fluid within the heat exchanger through the zigzag path. This allows for more heat exchange time between the hot and cold fluids, thereby improving the heat exchange efficiency of the device.

[0019] 2. By setting a recess change mechanism, the second sliding block is driven to move downward. When the rectangular block on one side of the second sliding block moves downward and contacts the bottom of the second limiting groove inside the first sliding block, the first sliding block is driven to move downward under the action of the second sliding block, thus forming a stepped recess. When the third sliding block moves upward, the first and second sliding blocks are reset under the action of the first return spring, thus forming a stepped convex state. As the connecting plate moves up and down, it can drive the first, second and third sliding blocks to form a continuous change of stepped recess and convex. This allows the fluid to continuously contact new heat exchange surfaces during flow, breaking the boundary layer thermal resistance. At the same time, when the water flows through the expansion structure, turbulence is generated due to surface undulation, which improves the heat exchange efficiency of the device.

[0020] 3. By setting up a rotating mechanism, the water flow at the bottom of the rotating plate can pass through the flow channel. At the same time, when the rotating plate flips to a certain angle and then resets, the cold water forms a certain "push-pull" pulse on the inside of the rectangular channel. This pulse is superimposed on the stepped depressions and convexities during contraction, causing the fluid to produce a spiral flow similar to an "8", which further increases the turbulence of the water flow. Meanwhile, the two streams form a shear layer and vortex behind the rotating plate. When the vortex impacts the heat exchange surface, it destroys the boundary layer, reducing the thermal resistance and further improving the heat exchange efficiency of the device.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" 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 communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0034] Please see Figures 1-10 This embodiment provides an energy-saving volumetric heat exchanger based on a pillow plate, comprising: a shell 1, three pillow plates 4 installed on the inner side of the shell 1, a second water storage shell 6 fixedly connected to the inlet and outlet of each of the three pillow plates 4, a second connecting pipe 3 installed at one end of each of the two second water storage shells 6, and the second connecting pipe 3 passing through to the outside of the shell 1 and connected to an external water pipe, two sets of first water storage shells 5 fixedly connected to the inner side of the shell 1, two in each set of first water storage shells 5, and three third connecting pipes 7 fixedly connected to one side of each first water storage shell 5, two heat medium cavities 24 opened on the inner side of each pillow plate 4, the other end of each third connecting pipe 7 communicating with the inner side of a heat medium cavity 24, a first connecting pipe 2 installed on the other side of the first water storage shell 5, and the first connecting pipe 2 passing through to the outside of the shell 1 and connected to an external water pipe, and a protrusion-concavity changing mechanism and a rotation mechanism provided on the inner side of the pillow plate 4;

[0035] When heat exchange is required, the operator connects the first connecting pipe 2 and the second connecting pipe 3 to the external pipes, and pours the heat medium and cold water into the inside of the first connecting pipe 2 and the second connecting pipe 3 on the right side, respectively. At this time, the heat medium flows inside the heat medium cavity 24, and the heat is conducted through 40 to the cold water between the two pillow plates 4 in the shell, heating the cold water. At the same time, the pillow plates 4 are distributed in a zigzag pattern, causing the cold water to change direction multiple times during the flow, forming a "bend" effect. This causes eddies and turbulence to be generated at the bends, which disrupts the boundary layer, reduces thermal resistance, and the zigzag path extends the flow distance of the fluid in the heat exchanger, giving the hot and cold fluids more time to exchange heat, thereby improving the heat exchange efficiency of the device.

[0036] Please see Figures 2-8 The protrusion-recession mechanism includes multiple sets of rectangular grooves 8 on the inner side of a pillow-shaped plate 4. Each set of rectangular grooves 8 has multiple grooves. Each rectangular groove 8 has two first sliding blocks 9, two second sliding blocks 10, and one third sliding block 11 on its inner side. A second return spring 22 is installed at the bottom of each first sliding block 9 and each second sliding block 10, connected to the inner side of the rectangular groove 8. A first limiting groove 17 is provided on the inner side of each of the rectangular grooves 8, the first sliding blocks 9, and the second sliding blocks 10. A limiting block 20 is fixedly connected to one end of each of the second sliding blocks 10 and the first sliding blocks 9, and to both ends of the third sliding block 11. Each limiting block 20 is slidably connected to the inner side of a first limiting groove 17. The protrusion-recession mechanism also includes a second limiting groove 18 on the inner side of each of the first sliding blocks 9 and the second sliding blocks 10, and the second limiting groove 18 is connected to the first limiting groove 17. 7. A rectangular block 19 is fixedly connected to one side of the limiting block 20, which is fixedly connected to the inner side of the second sliding block 10 and the third sliding block 11. A driving mechanism is provided at the bottom of the rectangular block 19. The driving mechanism includes a connecting rod 27 fixedly connected to the bottom of the third sliding block 11. Multiple sets of third limiting grooves 29 are opened on the inner side of the rectangular groove 8. Multiple sets of third limiting grooves 29 are provided in each set. Each third limiting groove 29 is connected to the inner side of the rectangular groove 8. A connecting plate 28 is slidably connected to the inner side of each set of third limiting grooves 29. The connecting rod 27 is fixedly connected to the inner side of the connecting plate 28. The driving mechanism also includes multiple second mounting grooves 25 opened on the inner side of each pillow plate 4. A driving motor 26 is installed on the inner side of each second mounting groove 25. The output end of the driving motor 26 passes through the inner side of the rectangular groove 8 and is fixedly connected to the connecting plate 28.

[0037] The drive motor 26 is controlled by a PLC controller, which can control the intermittent start of the drive motor 26. When the operator pours hot medium and cold water into the inside of the first connecting pipe 2 and the second connecting pipe 3 on the right, the PLC controller starts the drive motor 26. The output end of the drive motor 26 drives the connecting plate 28 to move up and down, thereby driving the connecting rod 27 to move up and down, which in turn drives the third sliding block 11 to move up and down. When the third sliding block 11 moves downward, it drives the rectangular blocks 19 on both sides of the third sliding block 11 to move downward. When the rectangular blocks 19 move downward to contact the bottom of the second limiting groove 18 inside the second sliding block 10, they drive the second sliding block 10 to move downward. When the rectangular block 19 moves downwards and contacts the bottom of the second limiting groove 18 inside the first sliding block 9, the first sliding block 9 moves downwards under the action of the second sliding block 10, thus forming a stepped depression. When the third sliding block 11 moves upwards, the first sliding block 9 and the second sliding block 10 are reset under the action of the first return spring 15, thus forming a stepped protrusion. As the connecting plate 28 moves up and down, it can drive the first sliding block 9, the second sliding block 10 and the third sliding block 11 to form a continuous change of stepped depression and protrusion. This allows the fluid to continuously contact new heat exchange surfaces during flow, breaking the boundary layer thermal resistance. At the same time, when the water flows through the expansion structure, turbulence is generated due to the surface undulation, which improves the heat exchange efficiency of the device and thus improves the overall practicality of the device.

[0038] Please see Figures 4 to 10 The rotating mechanism includes multiple first mounting slots 12 formed inside the first sliding block 9, the second sliding block 10, and the third sliding block 11. Each first mounting slot 12 has one or two rotating rods 13 rotatably connected to its outer wall. Each rotating rod 13 has a rotating plate 14 fixedly connected to its outer wall. A first return spring 15 is installed between the bottom of the rotating plate 14 and the inner side of the first mounting slot 12. The rotating mechanism also includes through slots 21 formed inside the first sliding block 9, the second sliding block 10, and the third sliding block 11. The through slots 21 communicate with the first mounting slots 12 and the rectangular slots 8, respectively. Five drive rods 23 are fixedly connected to the inner side of the rectangular slots 8. The lengths of the five drive rods 23 inside each rectangular slot 8 increase sequentially from the center to both sides.

[0039] When the second sliding block 10 drives the first sliding block 9 to move downwards, the first sliding block 9, the second sliding block 10, and the third sliding block 11 move downwards simultaneously. When the five drive rods 23 pass through the inner side of the through groove 21 and contact the rotating plate 14, they push the six rotating plates 14 to rotate under the action of the drive rods 23. This causes the rotating plates 14 to flip at a certain angle, which guides the water flow from both sides of the rotating plates 14 and allows the water at the bottom of the rotating plates 14 to pass through the flow groove 16. During the process of the rotating plates 14 flipping at a certain angle and then resetting, the cold water forms a certain "push-pull" pulse on the inner side of the rectangular groove 8. This pulse, combined with the stepped depressions and protrusions during contraction, causes the fluid to produce a spiral flow similar to an "8", further increasing the turbulence of the water flow. At the same time, the two streams form a shear layer and vortex behind the rotating plate 14. When the vortex impacts the heat exchange surface, it destroys the boundary layer, reducing the thermal resistance and further improving the heat exchange efficiency of the device.

[0040] The following describes a method for using an energy-saving volumetric heat exchanger based on a pillow plate, comprising the following steps:

[0041] S1. When heat exchange is required, the operator connects the first connecting pipe 2 and the second connecting pipe 3 to the external pipes, and pours the heat medium and cold water into the inside of the first connecting pipe 2 and the second connecting pipe 3 on the right side, respectively. At this time, the heat medium flows inside the heat medium cavity 24, and the heat is conducted through 40 to the cold water between the two pillow plates 4 in the shell, heating the cold water. At the same time, the pillow plates 4 are distributed in a zigzag pattern, causing the cold water to change direction multiple times during the flow, forming a "bend" effect. This causes the cold water to generate eddies and turbulence at the bends, destroying the boundary layer, reducing thermal resistance, and the zigzag path extends the flow distance of the fluid in the heat exchanger, giving the hot and cold fluids more time to exchange heat, thereby improving the heat exchange efficiency of the device.

[0042] S2. The drive motor 26 is controlled by a PLC controller, which can control the intermittent start of the drive motor 26. When the operator pours hot medium and cold water into the inside of the first connecting pipe 2 and the second connecting pipe 3 on the right, the PLC controller starts the drive motor 26. The output end of the drive motor 26 drives the connecting plate 28 to move up and down, thereby driving the connecting rod 27 to move up and down, which in turn drives the third sliding block 11 to move up and down. When the third sliding block 11 moves downward, it drives the rectangular blocks 19 on both sides of the third sliding block 11 to move downward. When the rectangular blocks 19 move downward to contact the bottom of the second limiting groove 18 inside the second sliding block 10, they drive the second sliding block 10 to move downward. When the rectangular block 19 on the side moves downward and contacts the bottom of the second limiting groove 18 inside the first sliding block 9, the first sliding block 9 moves downward under the action of the second sliding block 10, thus forming a stepped depression. When the third sliding block 11 moves upward, the first sliding block 9 and the second sliding block 10 are reset under the action of the first return spring 15, thus forming a stepped convex state. As the connecting plate 28 moves up and down, it can drive the first sliding block 9, the second sliding block 10 and the third sliding block 11 to form a continuous change of stepped depression and convex. This allows the fluid to continuously contact new heat exchange surfaces during flow, breaking the boundary layer thermal resistance. At the same time, when the water flows through the expansion structure, turbulence is generated due to the surface undulation, which improves the heat exchange efficiency of the device and thus improves the overall practicality of the device.

[0043] S3. When the second sliding block 10 drives the first sliding block 9 to move downward, the first sliding block 9, the second sliding block 10, and the third sliding block 11 move downward simultaneously. When the five drive rods 23 pass through the inner side of the through groove 21 and contact the rotating plate 14, the six rotating plates 14 are pushed to rotate under the action of the drive rods 23, thereby pushing the rotating plate 14 to flip to a certain angle. This allows water to flow from both sides of the rotating plate 14 and the water at the bottom of the rotating plate 14 to pass through the flow groove 16. At the same time, during the process of the rotating plate 14 flipping to a certain angle and then resetting, the cold water forms a certain "push-pull" pulse on the inner side of the rectangular groove 8. This pulse, combined with the stepped depressions and protrusions during contraction, causes the fluid to produce a spiral flow similar to an "8", further increasing the turbulence of the water flow. Meanwhile, the two streams form a shear layer and vortex behind the rotating plate 14. When the vortex impacts the heat exchange surface, it destroys the boundary layer, reducing the thermal resistance and further improving the heat exchange efficiency of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
