Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and in particular to a heat exchange regulating device and a plate heat exchanger. Background Technology

[0002] Currently, plate heat exchangers, as highly efficient heat exchange devices, are widely used in industrial and civil fields, especially in hot and cold water exchange systems. These heat exchangers typically consist of multiple layers of corrugated metal plates connected by brazing to form multiple isolated main channels, each with its own independent inlet and outlet ports. The hot and cold media flow counter-currently in adjacent plate channels, thus achieving highly efficient heat exchange.

[0003] However, in practical applications, brazed plate heat exchangers are usually integrated into CDU (cooling distribution unit) cabinets. Although this type of structure has good heat exchange performance, its manufacturing cost is relatively high, and once the structure is formed, it is not easy to adjust flexibly, which leads to its limited applicability to heat exchange scenarios.

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0062] This application provides a heat exchange regulating device and a plate heat exchanger. Please refer to [link / reference]. Figures 1 to 11 .

[0063] Firstly, this application provides a heat exchange regulating device that can be applied to heat exchangers. It is understood that this heat exchange regulating device is mainly used in plate heat exchangers, which are primarily composed of multiple plates 211, sealing gaskets, and main flow channels 21. Each plate 211 is sealed by the gaskets and arranged in a certain manner, allowing hot and cold fluids to flow separately between adjacent plates, forming alternating main flow channels 21. When the hot and cold fluids flow in opposite directions or in parallel on both sides of the multiple plates 211, heat is transferred from the high-temperature fluid to the low-temperature fluid through the plates 211, thereby achieving efficient heat exchange.

[0064] In some implementations, combined with Figures 1 to 3 The heat exchange regulating device includes a sealing component 1 and an regulating component 3. The sealing component 1 is configured to be inserted into the main flow channel 21 of the heat exchanger and arranged axially along the main flow channel 21 to selectively block or connect the main flow channel 21 through which the hot and cold media flow. It can be understood that the external dimensions of the sealing component 1 are adapted to the channel dimensions of the main flow channel 21, and its outer surface can be annular. In its initial state, the sealing component 1 has a certain gap with the inner wall of the main flow channel 21, allowing it to be inserted relatively freely into the main flow channel 21 without radial contact with the channel wall. The regulating component 3 is connected to the tail end or one end face of the sealing component 1, and is structurally detachable through helical propulsion, sliding engagement, magnetic drive, or other means. The regulating component 3 not only has the ability to drive the sealing component 1 to move axially along the main flow channel 21, but also has the function of driving the sealing component 1 to undergo radial deformation. For example, the adjusting component 3 can expand the radial dimension of the sealing component 1 by tightening or pushing it out, so that the outer wall of the sealing component 1 forms a radial stop contact with the inner wall of the main flow channel 21 in an outwardly expanding state, thereby sealing the main flow channel 21. Under this structure, by changing the insertion depth of the sealing component 1 in the main flow channel 21, the range of the blocked fluid can be adjusted, thereby regulating the flow path of the hot and cold media and the flow ratio of the heat exchange medium in the plate heat exchanger to a certain extent, thus affecting the overall heat exchange performance. In addition, through the function of the adjusting component 3, the sealing component 1 can be switched between a blocked state and a connected state, realizing the connection or blockage of the main flow channel 21 without replacing the components, which is beneficial for the rapid adaptation of the plate heat exchanger in different application scenarios and improves the flexibility of use.

[0065] Specifically, the radial deformation of the sealing component 1 can be achieved through a preset elastic structure or compressible material, such as an elastic rubber ring, a corrugated elastomer, or a material with shape memory properties. The driving action of the adjusting component 3 is achieved through rotation, pushing, pulling, or other means to transmit force. During the radial deformation of the sealing component 1, its outer wall will contact the inner wall of the main flow channel 21 after deformation, thereby effectively restricting the passage of hot and cold fluids. After the deformation is released, it can return to its initial state and reconnect the fluid path of the main flow channel 21. This structure not only has good mechanical response capability, but also avoids the adjustment rigidity problem caused by structural integration to a certain extent, making the plate heat exchanger more flexible and efficient in regulating hot and cold flow, and helping to reduce the energy efficiency loss of the heat exchanger due to scenario mismatch. Furthermore, the "connection" in "adjusting component 3 is connected to sealing component 1" can specifically refer to threaded connection, slot fit, slide rail guide structure, or other detachable connection methods to ensure the convenience of component assembly and subsequent maintenance. "Moving along the main channel 21" means that the adjusting component 3 can push or pull the sealing component 1 along the length of the main channel 21, allowing the sealing component 1 to move relative to different positions, further expanding the adjustment range. "Radial deformation" refers to the lateral dimensional change of the sealing component 1 under the action of the adjusting component 3; it is not a material fracture or permanent damage, but a recoverable deformation caused by elasticity or structural stress. In summary, through the above structural arrangement, dynamic adjustment of the fluid channel of the plate heat exchanger can be achieved to a certain extent, improving heat exchange efficiency and broadening its application capabilities in various heat exchange scenarios.

[0066] In some embodiments, combined with Figure 3 , Figure 4The sealing component 1 includes an elastic part 11, which is inserted into the main channel 21, and the cross-sectional shape of the elastic part 11 is adapted to the cross-sectional shape of the main channel 21. Specifically, the elastic part 11 can be made of materials with compressibility and a certain degree of resilience, such as elastic rubber, silicone, or polyurethane, and has good elastic deformation capability. When the elastic part 11 is inserted into the main channel 21, it is in an uncompressed state, that is, its outer diameter is slightly smaller than or equal to the inner diameter of the main channel 21, thereby achieving smooth insertion. When the adjusting component 3 applies a driving force to the sealing component 1, the elastic part 11 undergoes radial expansion deformation under the action of axial force or rotational force, causing its outer surface to extend towards the inner wall of the main channel 21 to a certain extent, and forming a relatively tight contact with the inner wall of the main channel 21, thereby realizing the blocking function of the hot and cold fluid channel. It can be understood that the advantage of the above structural design is that the compressibility of the elastic part 11 not only facilitates the sealing function of the main channel 21, but also facilitates subsequent state switching and component disassembly, improving the adjustment flexibility and service life of the device. When sealing is not required, the elastic part 11 can return to its original state by releasing the driving force of the adjusting member 3, re-creating a gap with the inner wall of the main channel 21, thereby achieving communication between the hot and cold media and effectively enhancing the adaptability of the heat exchange regulating device under different application requirements. Furthermore, the "plug-in fit" in this embodiment should be understood as an assembly form that allows relative movement between components but has a positioning function; that is, the elastic part 11 and the main channel 21 have a sliding or interference fit relationship, and its tightness can be set according to the material's elastic coefficient and structural dimensions to achieve good sealing performance and convenient assembly and disassembly operations. Therefore, the setting of the elastic part 11 in the sealing member 1 is beneficial to achieving structural simplification and functional integration, and to a certain extent improves the response efficiency and controllability of the heat exchange regulating device to hot and cold flow states.

[0067] In some implementations, combined with Figures 3 to 5The elastic part 11 has an adjusting groove 111, and a portion of the adjusting member 3 is disposed within the adjusting groove 111 to drive the elastic part 11 to undergo radial elastic deformation, thereby blocking / connecting the main flow channels 21 located on both sides of it. Furthermore, the opening of the adjusting groove 111 is aligned with the inlet and outlet of the main flow channel 21 to facilitate the insertion and engagement of the adjusting member 3. Thus, a portion of the structure of the adjusting member 3 is located within the adjusting groove 111. The adjusting member 3 can apply an inward-outward supporting or pushing force to the elastic part 11 from within the adjusting groove 111 by means of axial movement or rotation, thereby causing the elastic part 11 to undergo radial elastic deformation. Specifically, when the adjusting member 3 is inserted and an external force is applied to the adjusting groove 111, the peripheral wall of the adjusting groove 111 expands from the inside under the drive of the adjusting member 3, thereby causing the outer side of the elastic part 11 to expand and deform radially towards the main flow channel 21, causing its outer wall to gradually approach or abut against the inner peripheral wall of the main flow channel 21, and to a certain extent, to block the hot and cold medium channels. Conversely, when the adjusting member 3 releases the thrust acting on the inner wall of the adjusting tank 111, the elastic part 11 can recover its original position by means of the material's restorative contraction, restoring the gap between its outer wall and the main channel 21, thereby connecting the fluid paths at both ends of the main channel 21. It can be understood that the above structural arrangement facilitates control of the expansion and contraction process of the elastic part 11 from within the adjusting tank 111, improving the sensitivity of the adjustment response and the controllability of the operation, while avoiding instability or inaccurate displacement of the sealing member 1 caused by external loading. In this embodiment, the "adjusting tank 111" can specifically be a through-cavity, a blind slot, a symmetrically distributed interlocking channel, etc., matched accordingly to the shape of the elastic part 11 and the shape of the adjusting member 3. "The main channels 21 on both sides" refers to the hot and cold fluid channels corresponding to the main channels 21 within a certain range before and after or above and below the elastic part 11. This description is not limited to a fixed direction and is usually determined by the layout of the heat exchanger's main channels 21. Furthermore, the adjusting component 3 can adopt structures such as wedge-shaped pushers, expansion mandrels, and spring-loaded components. It is inserted into the adjusting groove 111 through a preset mating relationship and realizes a radial pushing process from the inside to the outside. The above structural design improves the tightness and ease of operation of the sealing component 1 to a certain extent, and also provides space support for subsequent modular integration design, which is beneficial to improving the adjustability and application breadth of the plate heat exchanger.

[0068] In some embodiments, such as Figures 7 to 9As shown, the adjusting member 3 includes a pushing part 31 and an abutting part 32, both of which are movably disposed within the adjusting groove 111. The abutting part 32 is configured to move radially along the adjusting groove 111 under the action of the pushing part 31, thereby driving the elastic part 11 to undergo radial elastic deformation through the inner wall of the adjusting groove 111. Specifically, the pushing part 31 and the abutting part 32 can adopt a wedge-fit structure, that is, the end of the pushing part 31 is provided with a slope or groove. When the pushing part 31 advances longitudinally along the adjusting groove 111, it slides relative to the slope mating surface of the abutting part 32, thereby converting the axial thrust into the radial displacement force of the abutting part 32, causing the abutting part 32 to move towards the inner wall of the adjusting groove 111 and undergo displacement. During the radial movement of the contact part 32, its outer surface will come into contact with the inner wall of the adjusting groove 111, and apply support or pushing force to the elastic part 11 from the inside out, further causing the elastic part 11 to expand and deform in the radial direction of the main channel 21, that is, to generate radial elastic deformation.

[0069] It is understandable that the above structural design improves the accuracy and stability of the adjustment to a certain extent, making it particularly suitable for applications requiring deformation control within a small structural space. Furthermore, the "movable setting" of the "push part 31" and the "abutment part 32" should be understood as meaning that they have a certain degree of freedom of movement within the adjustment tank 111, rather than being fixedly connected. This configuration helps the heat exchange adjustment device maintain its elastic response capability and mechanical integrity during multiple adjustments. This structural arrangement not only improves the response sensitivity of the heat exchange adjustment device during the switching process between hot and cold fluid channels, but also allows for flexible setting of the deformation degree of the elastic part 11 according to usage requirements, adapting to different flow rate adjustment and heat exchange efficiency needs. Simultaneously, this modular push and abutment structure facilitates maintenance and replacement, enhancing the system's sustainable usability. Overall, the push part 31, the abutment part 32, and the adjustment tank 111 form a three-dimensional force transmission path, realizing a complete conversion process from external force input to elastic deformation output, providing a structural basis for the dynamic adjustment of the plate heat exchanger's heat exchange performance.

[0070] For example, the pushing part 31 is slidably disposed within the adjusting groove 111 along the axial direction of the adjusting groove 111. One side of the abutting part 32 is in contact with the pushing part 31, and the other side is in contact with the inner wall of the adjusting groove 111. During the process of the pushing part 31 sliding axially from the inner bottom wall of the adjusting groove 111 to the groove opening, the abutting part 32 undergoes radial displacement away from the central axis of the adjusting groove 111 under the action of the pushing part 31, so that the sealing member 1 blocks the main flow channels 21 located on both sides of it. Specifically, the shape of the pushing part 31 is in a guiding fit relationship with the inner wall of the adjusting groove 111 in the axial direction, allowing it to slide freely along the central axis within the groove. One end of the pushing part 31 is close to the groove opening of the adjusting groove 111, and the other end is close to the inner bottom wall of the adjusting groove 111. By applying external force (e.g., by screw tightening, push rod pressing, etc.), the pushing part 31 can move from the bottom of the groove towards the groove opening within the adjusting groove 111. The abutment portion 32 is disposed between the pushing portion 31 and the inner wall of the adjusting groove 111, with one side fitting against the pushing portion 31 and the other side fitting against the inner wall of the adjusting groove 111. The sliding movement of the pushing portion 31 causes a squeezing relationship between it and the abutment portion 32. Especially when the pushing portion 31 has an inclined surface or wedge structure, it can gradually push the abutment portion 32 to shift in the radial direction of the adjusting groove 111 during its sliding process. Since the pushing force acts on the side of the abutment portion 32 near the central axis, the abutment portion 32 will move away from the central axis of the adjusting groove 111 when it is subjected to the inclined surface thrust. This causes the elastic portion 11 connected to it to produce outward radial elastic deformation, thereby causing the sealing member 1 to expand towards the inner peripheral wall of the main channel 21 as a whole, forming an effective sealing or blocking effect to a certain extent, and realizing the blockage of the hot and cold fluid channel. It should be noted that in this embodiment, the "inner bottom wall of the regulating tank 111" and the "slot opening" should be understood as the two ends of the regulating tank 111 in the axial direction, where the inner bottom wall is the closed end and the slot opening is the open end; the "central axis" refers to the symmetrical central axis of the regulating tank 111 itself, which is also the axial direction of the sliding path of the pushing part 31. Through the above structural arrangement, not only is the controllability of the action during the adjustment process effectively enhanced, but it also helps to smoothly convert the pushing force into radial deformation force, thereby achieving efficient switching of the blocking state without increasing the overall structural complexity, and thus effectively expanding the applicable scenarios and functional levels of the heat exchange regulating device to a certain extent.

[0071] In some examples, such as Figure 9 and Figure 11As shown, the pushing part 31 has a first inclined sliding surface 311, and the abutting part 32 has a second inclined sliding surface 321. The first inclined sliding surface 311 and the second inclined sliding surface 321 slide and abut against each other in the axial direction of the adjusting groove 111. When the pushing part 31 slides along the axial direction of the adjusting groove 111, its first inclined sliding surface 311 and second inclined sliding surface 321 slide relative to each other. During this process, the axial sliding force is converted into the radial displacement force of the abutting part 32, causing the abutting part 32 to move away from the central axis of the adjusting groove 111, thereby causing the elastic part 11 to expand radially toward the inner wall of the main flow channel 21, which is beneficial to effectively block the hot and cold fluid channels.

[0072] For example, to achieve more uniform circumferential deformation control of the elastic part 11, the adjusting member 3 includes multiple abutment parts 32, which are arranged circumferentially along the pushing part 31. The pushing part 31 has multiple first inclined sliding surfaces 311, and the second inclined sliding surface 321 of each abutment part 32 slides and abuts against a first inclined sliding surface 311. This multi-point synchronous cooperation structure helps the pushing part 31 drive each abutment part 32 to move outward radially synchronously during axial movement, so that the elastic part 11 produces a more uniform deformation in the entire circumferential direction, effectively improving the consistency and stability of the radial deformation of the sealing member 1. It should be further explained that the "first inclined sliding surface 311" and "second inclined sliding surface 321" here should be understood as inclined surface structures with a certain angle along the axial direction, used to realize the effective conversion of axial and radial forces. "Sliding abutment cooperation" refers to continuous contact between the two inclined surfaces and the transmission of force in relative movement, rather than simple static contact. This structure enhances the adaptability of the heat exchange regulating device to a certain extent in complex thermal environments and provides a reliable structural basis for the flexible adjustment of plate heat exchangers under multiple operating conditions.

[0073] For example, the angle between the first inclined sliding surface 311 and the central axis of the adjusting groove 111 ranges from 15° to 35°. Further, the angle between the first inclined sliding surface 311 and the central axis of the adjusting groove 111 is 25°. This angle range is primarily based on a balance between force transmission efficiency and structural response sensitivity. Specifically, when the pushing part 31 slides in the axial direction, the inclined surface contact relationship formed by the first inclined sliding surface 311 and the second inclined sliding surface 321 of the abutment part 32 gradually converts the axial sliding force into a radial pushing force, thereby driving the abutment part 32 to move radially and causing the elastic part 11 to deform radially, thus effectively blocking or connecting the main channel 21. If the angle is too small (less than 15°), although the force transmission efficiency can be increased, the radial displacement amplitude of the abutment part 32 will be significantly reduced, potentially leading to insufficient blocking effect; if the angle is too large (greater than 35°), although the radial displacement increases, the axial force required for pushing also increases, which is detrimental to the overall response sensitivity and ease of operation of the device. Therefore, by limiting the included angle to between 15° and 35°, and preferably 25°, a reasonable match between force transmission efficiency and structural controllability can be achieved to a certain extent.

[0074] It should be noted that the "angle" here should be understood as the acute angle between the first inclined sliding surface 311 and the central axis of the adjusting groove 111, and it is a static design angle that is directly determined during the manufacturing of the pushing part 31 and remains unchanged in actual application. The reasonable design of the above-mentioned structural angle is beneficial to improving the overall adjustment performance of the heat exchange regulating device.

[0075] In some embodiments, the elastic part 11 is made of rubber material. During the axial sliding of the pushing part 31 from the opening of the adjusting groove 111 to the inner bottom wall, the abutting part 32 undergoes radial displacement near the central axis of the adjusting groove 111 under the elastic deformation force of the elastic part 11, thereby connecting the main channels 21 located on both sides of the sealing member 1. It is understood that rubber material has good elastic recovery properties and certain temperature and corrosion resistance, which is beneficial for maintaining its deformation function over a long period in hot and cold media environments. As the pushing part 31 slides along the axial direction of the regulating trough 111 from the opening towards the inner bottom wall, the cooperation between it and the abutting part 32 gradually disengages. That is, the force exerted by the first inclined sliding surface 311 of the pushing part 31 on the second inclined sliding surface 321 of the abutting part 32 gradually decreases. After losing external force support, the abutting part 32 moves radially toward the central axis of the regulating trough 111 under the elastic force of the rubber elastic part 11 restoring its deformation. Ultimately, this causes the elastic part 11 to return to a non-blocking state, thereby connecting the main channels 21 located on both sides of the blocking member 1. At the same time, by using rubber as the material of the elastic part 11, the automatic reset function of the abutting part 32 and the elastic part 11 when the external force is removed can be achieved without the need for additional complex mechanisms, thereby improving the responsiveness and reusability of the heat exchange regulating device to a certain extent. It is worth noting that "radial displacement near the central axis" refers to the displacement of the contact part 32 towards the center of the regulating trough 111 by the elastic restoring force of the rubber elastic part 11, thereby causing the elastic part 11 to contract and release the blockage of the main channel 21. This structure ensures the blocking function while also facilitating the free switching of the on / off state, making it suitable for working environments where there is a dynamic adjustment requirement for heat exchange intensity.

[0076] In some examples, refer to Figure 5 , Figure 9 as well as Figure 11 The sealing component 1 also includes an anti-detachment part 12, which is disposed on the inner wall of the elastic part 11 and arranged circumferentially along the regulating groove 111. The anti-detachment part 12 and the abutment part 32 are in a stop-fitting engagement in the axial direction of the regulating groove 111 to restrict the abutment part 32 from detaching from the groove opening of the regulating groove 111. It can be understood that the main function of the anti-detachment part 12 is to restrict the movement of the abutment part 32 within the regulating groove 111, preventing the abutment part 32 from detaching from the groove opening, and ensuring that the engagement between the elastic part 11 and the abutment part 32 remains stable during the operation of the heat exchange regulating device. Specifically, the anti-detachment part 12 forms a physical restriction at the edge of the groove opening of the regulating groove 111, preventing the abutment part 32 from being pulled out of the groove by external force, thereby avoiding heat exchange device malfunctions due to excessive displacement or structural detachment.

[0077] For example, the anti-detachment part 12 is made of rubber material. Furthermore, the anti-detachment part 12 and the elastic part 11 are integrally injection molded. This design not only effectively enhances the overall structural strength of the anti-detachment part 12 and the elastic part 11, but also effectively prevents problems such as detachment and cracking at the joint between the two during long-term use, and maintains the good elastic deformation performance of the elastic part 11. Rubber material has good corrosion resistance and elasticity, and can effectively cope with changes caused by alternating flow of hot and cold fluids. By producing the anti-detachment part 12 and the elastic part 11 as a single unit, the connection links between components can be reduced, thereby improving the simplicity of the manufacturing process and reducing potential errors during assembly. It should be noted that the anti-detachment part 12 and the elastic part 11's stop-locking fit can effectively prevent malfunctions caused by blockage or misoperation in practical applications. Therefore, through this design, the sealing component 1 can maintain stable performance throughout the process of blocking and connecting the main flow channel 21. This structural design also provides beneficial protection for the long-term service life and stability of the heat exchange regulating device, especially its excellent stability performance after multiple operations.

[0078] In some implementations, such as Figures 4 to 6As shown, the regulating component 3 also includes a drive unit 33, one end of which is connected to the push unit 31, and the other end extends outside the main flow channel 21 and is driven by an external drive source. Further, the drive unit 33 includes a rod 331, one end of which is coaxially connected to the push unit 31, and the other end extends outside the regulating groove 111. This configuration facilitates precise position control of the push unit 31 and, by driving the rod 331 through an external drive source, adjusts the movement of the sealing component 1 within the main flow channel 21, thereby effectively achieving the switching and adjustment of the hot and cold fluid channels. Specifically, the rod 331 of the drive unit 33 is designed with one end coaxially connected to the push unit 31 and the other end extending outside the regulating groove 111. This structural configuration provides an interface for easy external operation of the heat exchange regulating device; the drive unit 33 can control the position of the push unit 31 through an external power source (such as manual rotation or an electric drive system). Controlled by an external transmission system, the pusher 31 can precisely slide axially within the regulating tank 111, driving the sealing member 1 to undergo radial deformation, thereby blocking or connecting the main flow channel 21. This design makes operation more convenient and allows for flexible adjustment of the heat exchanger's operating state according to actual needs. Furthermore, the drive unit 33 is coaxially connected to the pusher 31 via a rod 331, ensuring that the movement of the pusher 31 is synchronized with the rod 331, thus improving operational stability and consistency. The structure of the rod 331 allows it to extend outside the regulating tank 111, facilitating direct operation by the operator and effectively avoiding complex operations requiring direct contact with the interior of the regulating tank 111, thereby improving work efficiency. For more complex heat exchange regulation scenarios, the external transmission of the drive unit 33 ensures the flexibility of the entire system, allowing adjustment of the blocking length of the main flow channel 21 under different heat exchange requirements, thereby adjusting the heat exchange efficiency and meeting different operating conditions.

[0079] Some examples, such as Figures 4 to 6 As shown, the drive unit 33 also includes a rotating unit 332, which is rotatably mounted on the rod 331. When the rotating unit 332 rotates about the axis of the rod 331, the rod 331, under the action of the rotating unit 332, drives the pushing unit 31 to undergo axial displacement within the adjusting groove 111. This arrangement allows for precise control of the movement of the pushing unit 31 by rotating the rotating unit 332, thereby adjusting the closed or open state of the sealing member 1 within the main channel 21.

[0080] Furthermore, the rotating part 332 has a threaded hole 3321, and the rod 331 is a screw, which is threadedly engaged with the rotating part 332 through the threaded hole 3321. This configuration allows the rotation of the rotating part 332 to drive the rod 331 to move axially through the relative movement of the threads. During the rotation of the rotating part 332, the rotation of the screw drives the pushing part 31 to move along the axial direction of the adjusting groove 111, thereby achieving precise adjustment of the sealing component 1. Compared with other traditional operating methods, this threaded engagement design provides more stable and precise control, which helps to achieve reliable adjustment of the heat exchange regulating device under various operating conditions. It can be understood that the greatest advantage of the above-mentioned driving method lies in its efficient and precise control method. Through the rotation of the rotating part 332, not only can the axial displacement of the pushing part 31 be controlled, but the working state of the heat exchange device can also be flexibly adjusted according to actual needs. Due to the frictional characteristics of the threaded structure, the movement of the pushing part 31 is relatively smooth and easy to control, while effectively avoiding loosening or instability under high-frequency operation. At the same time, this structure is simple, easy to connect to external driving sources, and easy to maintain and operate.

[0081] In summary, through the threaded engagement between the rotating part 332 and the screw, the drive part 33 can achieve precise axial adjustment. The application of this structural design in heat exchange regulating devices not only effectively improves the adjustment accuracy of the equipment but also significantly increases its stability and operability. This innovative structure provides an effective technical solution for equipment requiring precise control of fluid flow or heat exchange processes, and is particularly suitable for environments or operating conditions requiring frequent adjustments to heat exchange performance.

[0082] In some implementations, combined with Figure 9 and Figure 11 One end face of the rotating part 332 is configured as an abutment surface 3322, which engages with the end face of the abutment part 32 axially in the adjusting groove 111. The main purpose of this design is to ensure that the rotating part 332 and the abutment part 32 can accurately align and limit movement during adjustment through the action of the abutment surface 3322. Specifically, the abutment surface 3322 of the rotating part 332 and the end face of the abutment part 32 effectively prevents excessive movement of the pushing part 31, avoiding possible excessive displacement or structural damage, thereby improving the stability and reliability of the equipment.

[0083] Furthermore, a displacement gap 1111 is formed within the adjusting groove 111 between the contact surface 3322 and the pushing part 31, allowing the pushing part 31 to slide axially. It is understood that this displacement gap 1111 not only ensures that the pushing part 31 can slide freely axially when driven by the rotating part 332, but also provides a certain degree of flexibility during rotation. This structural design allows the pushing part 31 to move freely axially within the adjusting groove 111, thereby further adjusting the position of the sealing member 1. Through the displacement gap 1111, the pushing part 31 can be adjusted within a certain range without excessive friction with the contact surface 3322 or hindering its normal movement.

[0084] Meanwhile, the above design has significant technical advantages. First, the design of the displacement gap 1111 makes the axial displacement of the pushing part 31 driven by the rotating part 332 more stable, avoiding uneven movement or inaccurate adjustment due to excessive friction or jamming. Simultaneously, the stop-locking fit of the contact surface 3322 effectively prevents the pushing part 31 from dislodging from the adjusting tank 111 during high-frequency or wide-range adjustments, thereby improving the stability and service life of the equipment. Second, the entire structure is simple and effective, providing precise adjustment and control, ensuring stable operation of the heat exchange device under various working conditions, and meeting the needs of precise control of fluid flow or heat exchange processes.

[0085] In summary, this embodiment further enhances the accuracy and stability of the heat exchange regulating device. Through the setting of the displacement gap 1111 and the anti-blocking mechanism, the smooth operation of the pushing part 31 throughout the regulating process can be ensured, and excessive friction or jamming between the pushing part 31 and the regulating tank 111 can be effectively avoided, thereby improving the reliability and ease of operation of the device. This structural design is suitable for heat exchange devices with high requirements for regulating accuracy and equipment stability.

[0086] In some implementations, combined with Figure 5 , Figure 9 and Figure 11The sealing component 1 also includes an anti-rotation part 13, which circumferentially abuts against the inner wall of the main channel 21. This design aims to prevent the elastic part 11 from rotating along with the rod 331 during adjustment, thus ensuring the normal axial movement of the pushing part 31. Specifically, when the rod 331 rotates, the torque it generates acts on the anti-rotation part 13. The friction between the anti-rotation part 13 and the inner wall of the main channel 21 is greater than the torque of the rod 331. Therefore, the anti-rotation part 13 effectively prevents the rotation of the elastic part 11, keeping it stationary. In this way, the pushing part 31 can achieve axial displacement within the adjusting groove 111, thereby completing the precise adjustment of the sealing component 1. The axial movement of the pushing part 31 requires the elastic part 11 to be stationary, because if the elastic part 11 rotates, the pushing part 31 will lose axial control, thus affecting the overall working effect of the heat exchange regulating device.

[0087] For example, multiple anti-rotation portions 13 are circumferentially arranged on the outer wall of the elastic portion 11. This arrangement allows the anti-rotation portions 13 to be evenly distributed circumferentially, effectively improving the anti-rotation effect and ensuring that the frictional force is evenly distributed around the entire elastic portion 11, further preventing rotation of the elastic portion 11 due to insufficient local friction. The even arrangement of multiple anti-rotation portions 13 provides a more stable stationary action, ensuring that the pushing portion 31 can smoothly perform axial displacement.

[0088] For example, the anti-rotation part 13 is made of rubber. The use of rubber not only provides good frictional properties, allowing the anti-rotation part 13 to effectively generate significant friction with the inner wall of the main channel 21, but also offers good elasticity and durability, making it suitable for applications in long-term working environments. By using rubber, the anti-rotation part 13 can maintain good working condition during repeated adjustments, avoiding unstable adjustment effects or malfunctions due to excessive wear. Furthermore, the anti-rotation part 13 and the elastic part 11 are integrally injection molded. This design makes the connection between the anti-rotation part 13 and the elastic part 11 more secure, avoiding the loosening or detachment problems that may occur in traditional methods. At the same time, the integral molding design simplifies the production process, improves production efficiency, and reduces costs. Because the anti-rotation part 13 and the elastic part 11 are integrally molded, their dimensions and structure can be more precisely controlled, further improving the stability and adjustment effect of the device.

[0089] In some examples, such as Figure 6 , Figure 9 and Figure 11As shown, the regulating member 3 also includes an extension 35, which is coaxially connected to the rotating part 332 and extends from inside the main channel 21 to the outside. It can be understood that the extension 35 allows the driving source of the regulating member 3 (e.g., a rotary handle or electric drive device) to be easily connected to the outside, enabling the operator to easily adjust the position of the pushing part 31 and thus control the state of the sealing member 1. In the heat exchange regulating device, the extension 35 of the regulating member 3 acts as a bridge between external transmission and internal adjustment, transmitting the external driving signal to the rotating part 332, allowing the rotating part 332 to effectively drive the pushing part 31 to perform the required axial displacement. Therefore, the design of the extension 35 effectively improves the operability and maintainability of the entire regulating device, making it particularly suitable for heat exchange systems requiring frequent adjustments.

[0090] For example, the extension 35 and the rotating part 332 are circumferentially limited. It can be understood that the circumferentially limited connection means that the extension 35 and the rotating part 332 are circumferentially fixed in the structure, that is, the extension 35 and the rotating part 332 cannot rotate relative to each other in the circumferential direction, thus achieving synchronous transmission. This ensures that the extension 35 can be stably connected to the rotating part 332 during rotation, avoiding relative displacement between the rotating part 332 and the extension 35, thereby ensuring the overall stability and accuracy of the adjusting component 3. The circumferentially limited connection effectively prevents deviation between the rotating part 332 and the extension 35, ensuring their coaxiality during adjustment and reducing potential inaccuracies or device damage due to positional deviations. The limited connection structure can also ensure uniform force transmission through reasonable design, making the adjusting device operate more smoothly, reducing friction or unnecessary force transmission, thereby extending the service life of the heat exchange adjusting device.

[0091] In summary, the coaxial connection and circumferential limiting connection between the extension 35 and the rotating part 332 give the entire regulating device high stability and operability. During long-term use, this design reduces the risk of misalignment or malfunction due to external interference, while enhancing regulation accuracy and response speed. This makes the heat exchange regulating device more reliable in various practical applications, especially under complex operating conditions, ensuring smooth regulation operations. Therefore, the linkage design of the extension 35 and the rotating part 332 not only provides a convenient control method but also enhances the overall performance of the device through a precise mechanical structure.

[0092] In some embodiments, such as Figure 6 , Figure 9 and Figure 11As shown, a positioning sub-part 351 is eccentrically provided on one end face of the extension 35, and a positioning groove 3323 is eccentrically provided on the rotating part 332. The positioning sub-part 351 and the positioning groove 3323 are slidably inserted into each other in the axial direction of the extension 35. This arrangement enables circumferential limiting of the extension 35 and the rotating part 332, thus providing stable rotational and axial displacement control. By sliding the positioning sub-part 351 into the positioning groove 3323, the relative position of the extension 35 and the rotating part 332 is effectively controlled, preventing displacement deviation or unnecessary loosening of the rotating part 332 during operation, thereby ensuring the accuracy and stability of the entire adjustment device. Specifically, the insertion of the positioning sub-part 351 into the positioning groove 3323 ensures that the rotating part 332 remains coaxial with the extension 35 during rotation, effectively avoiding inaccurate adjustment or increased frictional resistance due to misalignment. This design, through a rational configuration of the mechanical structure, enables the heat exchange regulating device to maintain a stable regulating effect during use and to cope with relatively complex operating environments. For example, when the regulating device needs to be adjusted by an external driving source, the cooperation between the positioning sub-part 351 and the positioning groove 3323 can guide the rotating part 332 to make precise displacement, thereby smoothly controlling the axial movement of the pushing part 31 within the regulating groove 111.

[0093] For example, an eccentrically formed fitting groove 352 is provided on one end face of the extension 35, and a portion of the positioning sub-part 351 is interference-fitted into the fitting groove 352. This further improves the connection stability between the extension 35 and the rotating part 332. The interference fit ensures that the positioning sub-part 351 maintains close contact with the rotating part 332 within the fitting groove 352, thereby enhancing the bonding force between the two and effectively preventing loosening due to long-term use. The interference fit provides a certain mechanical constraint, allowing the extension 35 to maintain a more stable state when the rotating part 332 is rotating, preventing it from shifting due to external forces. Through this structural design, the various components of the adjustment device achieve more stable mechanical linkage, which is beneficial to improving the service life and adjustment accuracy of the device.

[0094] In some implementations, combined with Figure 9 and Figure 11An axially oriented receiving groove 353 is provided on the extension 35 for inserting the portion of the rod 331 extending out of the rotating part 332. When the sealing member 1 blocks the main flow channels 21 on both sides, a redundant gap 3531 is formed between the inner end wall of the receiving groove 353 and the rod 331. It can be understood that the presence of the receiving groove 353 prevents interference between the rod 331 and the extension 35 after it undergoes helical rotation and axial displacement. The receiving groove 353 provides a redundant gap 3531 for the rod 331, ensuring a certain spatial distance between the inner end wall of the receiving groove 353 and the rod 331 when the sealing member 1 blocks the main flow channels 21 on both sides. The purpose of this design is to avoid physical contact between the rod 331 and the extension 35, thereby effectively preventing interference or friction.

[0095] Specifically, when the drive source drives the rod 331 through the rotating part 332, the rod 331 not only rotates around its axis but also undergoes axial displacement with the rotation. At this time, the receiving groove 353 between the extension 35 and the rotating part 332 provides a reasonable space, ensuring that the rod 331 is not physically constrained during movement and avoiding jamming due to narrow space. This redundant clearance 3531 effectively ensures the stability of the entire transmission system, prevents interference between components, and thus reduces the risk of wear and failure rate during long-term use.

[0096] Furthermore, the design of the receiving groove 353 also improves the adaptability of the entire transmission system to a certain extent. When facing different working conditions and changes in the external environment, the redundant clearance 3531 can adapt to possible dimensional deviations or component expansion, further improving the fault tolerance and stability of the device. Overall, the design of the receiving groove 353 optimizes the working efficiency of the entire heat exchange regulating device, effectively reduces the negative impact of mechanical shock on the structure, and ensures a smooth and efficient regulating process.

[0097] In some embodiments, reference is made to Figure 6The extension 35 has anti-slip textures 354 on its outer peripheral wall; and / or, the extension 35 is covered with an anti-slip material. It is understood that the anti-slip textures 354, by forming a regular pattern of raised or recessed structures on the outer peripheral wall of the extension 35, increase the friction between the extension and external components, thereby effectively preventing the extension 35 from slipping due to hand operation or external forces during use. This design effectively provides operators with better grip and stability when adjusting the device, especially in situations requiring greater turning force, effectively reducing improper operation or errors caused by slippage. Furthermore, the anti-slip material further enhances the grip of the extension 35. The anti-slip material is typically made of materials with a high coefficient of friction, such as rubber or polyurethane. These materials significantly increase the surface friction of the extension 35, preventing adjustment failures due to accidental hand slippage during operation, thereby effectively improving the safety and reliability of the device.

[0098] In some embodiments, when the sealing member 1 connects the main channels 21 on both sides, the circumferential gap width between the elastic part 11 and the inner wall of the main channel 21 is configured to be 2mm-3mm. This is understood to ensure that the elastic part 11 maintains a certain contact pressure with the inner wall of the main channel 21, avoiding leakage due to inadequate sealing. This gap size effectively ensures the free movement of the elastic part 11 and also ensures that the elastic part 11 maintains appropriate elastic deformation during the operation of the pushing part 31, further enhancing the sealing effect. A smaller gap helps improve the sealing accuracy and avoids media leakage or a decrease in heat exchange efficiency.

[0099] For example, the elastic part 11 is configured to expand radially by 2.7mm-3.0mm when the pushing part 31 slides 6mm axially from the inner bottom wall of the adjusting groove 111 towards the groove opening. Further, the elastic part 11 is configured to expand radially by 2.8mm when the pushing part 31 slides 6mm axially from the inner bottom wall of the adjusting groove 111 towards the groove opening. This configuration indicates that the elastic part 11 can fully utilize its elastic deformation during operation, ensuring a tight contact with the inner wall of the main channel 21. This design effectively improves the adjustment accuracy and sealing performance of the device, ensuring that the elastic part 11 maintains a good sealing effect even during frequent axial movements, and avoiding energy loss or unstable heat exchange due to poor sealing.

[0100] In some embodiments, the unilateral pre-compression of the elastic part 11 on the inner wall of the main channel 21 is configured to be 0.2mm-0.5mm. Further, the unilateral pre-compression of the elastic part 11 on the inner wall of the main channel 21 is configured to be 0.3mm. It can be understood that during the process of the pushing part 31 driving the elastic part 11 to slide axially towards the opening of the adjusting groove 111 and undergoing radial expansion, a suitable unilateral pre-compression is formed between the elastic part 11 and the inner wall of the main channel 21, thereby improving the contact tightness between the elastic part 11 and the inner wall of the main channel 21 to a certain extent, and helping to enhance its stability and reliability in a sealed state. The so-called "unilateral pre-compression" refers to the radial compression of the elastic part 11 in one direction after it is installed or expanded to the inner wall of the main channel 21. This compression value can effectively reflect the degree of local elastic fit of the elastic part 11 to the inner wall of the main channel 21. By setting a single-sided preload of 0.3 mm, a stable sealing contact between the elastic part 11 and the inner wall of the main channel 21 can be maintained without affecting the free sliding of the elastic part 11. This structure can further reduce the potential risk of media leakage, especially in heat exchange regulating devices involving alternating flow of hot and cold media. At the same time, the presence of the preload also provides an initial tension basis for the subsequent radial recovery and bonding of the elastic part 11, ensuring that it is always in a reliable elastic bonding state during actual operation. This makes the heat exchange regulating function of the device more stable and reliable, meeting the comprehensive requirements for sealing and sensitive regulation response under dynamic operating conditions.

[0101] Secondly, combining Figure 1 , Figure 2 , Figure 9 and Figure 11 This application also provides a plate heat exchanger, including the heat exchange regulating device mentioned in the first aspect and a heat exchange body 2. At least two main flow channels 21 are arranged in parallel on the heat exchange body 2. These main flow channels 21 can be used for parallel or counter-current flow of media under different operating conditions to optimize and improve heat exchange efficiency. Furthermore, the heat exchange regulating device is inserted into the main flow channel 21 and is used to adjust the flow area, on / off state, or flow velocity within the channel during operation, thereby improving the response capability to temperature or pressure changes.

[0102] For example, the heat exchanger body 2 includes multiple overlapping plates 211, each plate 211 having through holes along its thickness direction. The through holes of the multiple plates 211 are aligned to define the main flow channel 21, thus giving the plate heat exchanger a multi-channel structure, which is beneficial for achieving distributed or regionalized heat exchange control. It can be understood that, compared to traditional plate heat exchanger structures, this structure increases the number of flow channels per unit volume and facilitates the arrangement of multiple heat exchange adjustment devices, thereby enabling real-time adjustment of heat exchange parameters with higher precision and flexibility. Furthermore, the heat exchange adjustment devices, through their adaptation and cooperation with the main flow channel 21, can achieve modular replacement or maintenance without disassembling the entire heat exchanger, thereby improving the reliability and maintainability of the equipment. During assembly, the plates 211 can be connected by welding, clamping, or sealing gaskets to form the required fluid isolation channels, while the heat exchange adjustment devices are stably fixed through the limiting fit and elastic interference between their outer peripheral structure and the inner wall of the main flow channel 21, which to a certain extent helps to enhance the sealing and stability of the overall structure. In summary, this embodiment effectively enhances the heat exchanger's flexible adjustment capability in multiple application scenarios by integrating the stacked plate structure 211 of the heat exchange body 2 with the heat exchange adjustment device, and has strong engineering adaptability.

[0103] In some embodiments, the number of plates 211 blocked axially by the sealing element 1 in the main flow channel 21 is 3 to 6. For example, the number of plates 211 blocked axially by the sealing element 1 in the main flow channel 21 is 5. It can be understood that the above-mentioned number setting is mainly based on a comprehensive trade-off between flow resistance, heat transfer efficiency, and structural stability. On the one hand, blocking an appropriate number of plates 211 is beneficial for forming a "dead zone" or buffer zone for fluid flow in a local area, thereby promoting fluid redistribution and contributing to the balanced regulation of the overall temperature field or flow velocity field. On the other hand, without affecting the continuity of the main flow channel of the entire heat exchanger, by blocking the through-hole area defined by 3 to 6 plates 211, a regulating cavity with a controllable length can be formed. The flow state within this cavity can be further controlled by the heat exchange regulating device, improving the controllability of the system flow state. It is worth noting that "the number of plates 211 is 3 to 6" means that in the axial direction of the main channel 21, the through holes corresponding to 3 to 6 consecutive plates 211 cannot be connected to form a complete flow channel due to the setting of the sealing component 1, rather than the structure of the plates 211 themselves being destroyed.

[0104] Furthermore, in another embodiment, the number of plates 211 blocked by the sealing element 1 can be specifically set to 5. This configuration has demonstrated good pressure stability and heat exchange efficiency in experimental tests, and has certain engineering adaptability and promotion value. Therefore, this embodiment, by specifically limiting the number of plates 211 blocked by the sealing element 1, provides an effective structural basis for the precise control of the heat exchange system in practical applications, and helps to further improve the operational reliability and flexibility of plate heat exchangers under complex operating conditions.
