Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and in particular to an integrated plate heat exchanger. Background Technology

[0002] Heat exchange is ubiquitous in industrial production and daily life, playing a crucial role in numerous fields such as refrigeration, chemical engineering, and energy. With rapid economic development and continuous technological advancements, various industries are increasingly demanding higher efficiency in heat exchange and greater equipment stability. Highly efficient heat exchange technologies can significantly improve energy utilization, reduce production costs, and promote sustainable industrial development. Plate heat exchangers, as a vital component of heat exchange equipment, directly impact the quality of the entire heat exchange process.

[0003] In the past, to achieve multiple functions such as gas-liquid separation, evaporation, oil separation, and condensation in one unit, the industry typically employed two methods. One method involved using welding to firmly connect multiple functional components, such as the gas-liquid separator, evaporator, oil separator, and condenser, into a single unit installed within the tank. This approach ensured a certain degree of integrity and stability. It was usually achieved through integral welding.

[0004] However, while welding achieves functional integration, it presents significant challenges for later maintenance. If one component fails, the integral nature of the weld makes disassembly and repair difficult, potentially malfunctioning other components. Furthermore, during actual processing and transportation, the welded parts typically require large transport vehicles for transport, and the shaking during transport can easily cause cracks at the weld joints, severely reducing product quality. Summary of the Invention

[0005] To address the inconvenience of later maintenance, the difficulty of assembly, and the product quality issues that arise during transportation, this application provides an integrated plate heat exchanger.

[0006] The integrated plate heat exchanger provided in this application adopts the following technical solution: An integrated plate heat exchanger includes at least three mounting pipes arranged sequentially and interconnectedly. One mounting pipe has an inner cavity for installing an evaporator and a gas-liquid separator, another mounting pipe is used for installing an oil separator, and the third mounting pipe is used for installing a condenser. The pipelines of the gas-liquid separator, evaporator, oil separator, and condenser are sequentially interconnected and form a heat exchange pipeline with an external compressor pipeline. A snap-fit ​​anti-detachment structure for quick assembly of the heat exchanger is provided between adjacent mounting pipes, and a support assembly is also provided on the outside of one of the mounting pipes.

[0007] By adopting the above technical solution, the evaporator, gas-liquid separator, oil separator, and condenser are installed in separate mounting pipes, changing the original method of welding the four functional components into one piece. This avoids the inconvenience of later maintenance and the problem of one component's failure affecting the overall operation. The snap-fit ​​anti-detachment structure between adjacent mounting pipes allows for quick assembly of the heat exchanger, achieving modular snap-fit ​​installation. The clamping and abutting components prevent the mounting pipes from detaching, ensuring operational stability. The support components on the outside provide support for the mounting pipes, further enhancing the overall structural stability.

[0008] Preferably, the snap-fit ​​anti-detachment structure includes a first groove and a second groove formed on one of the mounting tube ports, a plurality of clamping and sealing components installed in the first groove, a plurality of clamping and abutting components installed in the second groove, a flange formed on an adjacent mounting tube port for cooperating with the clamping and sealing components, a third groove formed on an adjacent mounting tube port, and an adjustable plug-in component disposed in the third groove for cooperating with the clamping and abutting components. The second groove and the third groove are connected, and the second groove is located between the first groove and the inner cavity of the mounting tube.

[0009] By adopting the above technical solution, adjacent mounting tubes can be quickly assembled using a snap-fit ​​anti-detachment structure when assembling an integrated plate heat exchanger. The first and second slots at the mounting tube ports are used to install the clamping sealing assembly and the clamping abutment assembly, respectively. The flanges at adjacent mounting tube ports mate with the clamping sealing assembly, and the adjustable plug-in in the third slot mates with the clamping abutment assembly. During the connection process, the connection between the second and third slots facilitates the coordinated operation of each component, effectively ensuring the sealing and connection safety between the two mounting tubes, preventing the mounting tubes from detaching, ensuring stable operation of the heat exchanger, and also facilitating subsequent maintenance and repair of the evaporator, gas-liquid separator, oil separator, or condenser within a single mounting tube.

[0010] Preferably, the clamping sealing assembly includes an annular bladder installed in the first groove and a clamping bladder communicating with the annular bladder. The clamping bladder includes a U-shaped shell and a flexible layer formed on the side of the U-shaped shell away from the annular bladder. When two adjacent mounting tubes are connected, the flange is embedded in the cavity of the flexible layer.

[0011] By adopting the above technical solution, when two adjacent mounting pipes are connected, the annular bladder is squeezed by the clamping and abutting components, thereby transmitting the pressure inside the annular bladder to the clamping bladder connected to it, causing the U-shaped shell to deform the flexible layer. As the mounting pipes move closer, the flanges at the ports of the adjacent mounting pipes gradually embed into the cavities of the flexible layer. During this process, the flexible layer tightly fits the flanges, using its own flexible properties to fill the gap between the flanges and the flexible layer, achieving a tight seal between the adjacent mounting pipes, effectively preventing media leakage, and ensuring the stability and safety of the heat exchanger operation. At the same time, the expanding flexible layer clamps the flanges, thereby ensuring the stability of the connection, achieving an anti-detachment effect, and increasing the safety of the heat exchanger.

[0012] Preferably, the clamping and abutting assembly includes a mounting plate fixed in the second groove, a pull rod disposed on the mounting plate, and a connecting block fixed at the end of the pull rod away from the mounting seat. The adjustable plug-in component includes a telescopic rod disposed in the third groove, a latch fixed at the end of the telescopic rod extending into the third groove, and a return spring disposed on the telescopic rod for resetting the latch. The side wall of the connecting block is provided with a slot for embedding the latch, and the inner wall of the third groove is provided with a groove for mounting the telescopic rod.

[0013] By adopting the above technical solution, the mounting plate is fixed in the second groove, providing stable support for the entire clamping and abutment assembly. A pull rod is mounted on the mounting plate, which can move the connecting block. The connecting block is connected to the pull rod, and its side wall has a slot for embedding the latch, serving a positioning and connecting function. The telescopic rod extends and retracts in the slot within the third groove, causing the latch to extend and retract. A return spring ensures the latch automatically returns to its original position after extension and retraction. When adjacent mounting pipes are connected, the connecting block presses against the latch, causing it to retract until the slot is directly below the latch. At this point, the latch, driven by the elastic force of the telescopic rod and the return spring, embeds itself into the slot of the connecting block, achieving the clamping connection of the two mounting pipes, preventing them from separating, ensuring the stability and reliability of the heat exchanger installation, and improving the overall performance and safety of the heat exchanger.

[0014] Preferably, the mounting plate has a mounting rod that slides on it, a mounting seat that rotates on the mounting rod, a torsion spring disposed between the mounting rod and the mounting seat, an abutment rod fixed on the mounting seat, and a wedge block disposed between the abutment rod and the side wall of the annular bladder. A through hole for mounting the wedge block is provided between the first groove and the second groove. The mounting plate has a guide groove for the mounting rod to slide toward the latch. In the initial state, the mounting rod is located at the end of the guide groove away from the latch. At this time, the latch is embedded in the groove. The abutment rod abuts against the end of the wedge block with the smaller thickness to prevent two adjacent mounting tubes from detaching.

[0015] By adopting the above technical solution, during the connection of two adjacent mounting pipes, the annular bladder is compressed, causing the wedge block to move and pushing the mounting rod to slide towards the latch within the guide groove. The mounting seat moves with the mounting rod, and the abutment rod rotates accordingly. The torsion spring provides a restoring force to the mounting seat, ensuring that the abutment rod is stably abutted against the wedge block. In the initial state, the mounting rod is located at the end of the guide groove away from the latch, the latch is embedded in the slot of the connecting block, and the abutment rod abuts against the thinner end of the wedge block. This series of dynamic actions work together to effectively prevent the two adjacent mounting pipes from detaching, ensuring the stability and reliability of the mounting pipe connection of the integrated plate heat exchanger. The adjustable abutment component allows for adjustment of the latch ejection depth and the force with which the abutment rod presses against the wedge block, thus better meeting the requirements for rapid assembly and anti-detachment.

[0016] Preferably, the groove connects to the outer wall of the mounting pipe, the telescopic rod slides in the groove, and an adjusting rod is rotatably connected to the end of the telescopic rod facing outward from the mounting pipe. The adjusting rod is threadedly connected to the groove, and a prismatic groove for embedding a prismatic wrench is provided at the end of the adjusting rod away from the telescopic rod.

[0017] By adopting the above technical solution, the groove connects to the outer wall of the installation pipe, allowing the telescopic rod to freely adjust its installation depth within the groove. The end of the telescopic rod facing outwards from the installation pipe is rotated to connect to the adjusting rod. When a diamond-shaped wrench is inserted into the diamond-shaped groove at the end of the adjusting rod away from the telescopic rod and rotated, the threaded connection between the adjusting rod and the groove causes the telescopic rod to move within the groove, enabling flexible adjustment of the telescopic rod's position. This allows for adjustment of the engagement state between the latch and the groove according to actual needs, while also adjusting the rotation angle of the mounting base. This ensures the stability and reliability of the snap-fit ​​anti-detachment structure, providing a more robust guarantee for the connection of adjacent installation pipes and improving the overall performance and maintainability of the integrated plate heat exchanger.

[0018] Preferably, the connecting block is frustum-shaped, and the end with the larger diameter is fixedly connected to the pull rod.

[0019] By adopting the above technical solution, when the frustum-shaped connecting block is engaged with the latch, the latch moves closer to the connecting block as the telescopic rod drives it. Due to the gradually changing diameter of the frustum shape of the connecting block, the latch can slide more smoothly along the surface of the connecting block and accurately embed into the slot. Compared with the traditional shape of the connecting block, this frustum-shaped design makes the latch engagement process more efficient and stable, effectively avoiding the latch from getting stuck or shifting during the connection process. This enhances the reliability and stability of the connection between adjacent installation pipes and improves the convenience and safety of the rapid assembly of the entire integrated plate heat exchanger.

[0020] Preferably, the end of the abutment rod away from the mounting base is arc-shaped.

[0021] By adopting the above technical solution, the end of the abutment rod away from the mounting base is arc-shaped. During the installation or removal of adjacent mounting tubes, the arc-shaped end can more smoothly contact and slide with other components. When adjacent mounting tubes are connected, the arc-shaped end of the abutment rod can more easily abut against the wedge block. Due to the design of the wedge block's inclined surface, the more the two mounting tubes are separated, the more the mounting base will be pulled towards the latch, thereby causing the abutment rod to press against the wedge block towards the annular bladder, further increasing the clamping capacity of the clamping bladder on the flange, ensuring the stability of the connection, and preventing the two mounting tubes from separating.

[0022] Preferably, the support assembly includes a first support fixed between one of the mounting tubes, a second support fixed to the outside of the other mounting tube, and a connecting support disposed between the first support and the second support.

[0023] By adopting the above technical solution, the installation pipe is supported by a support assembly consisting of a first support base, a second support base, and a connecting support, which enhances the overall stability and structural strength of the integrated plate heat exchanger and ensures the reliability of the heat exchanger during operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By installing the evaporator, gas-liquid separator, oil separator, and condenser in different mounting pipes, the problem of difficult maintenance caused by welding a single unit is avoided, and individual components can be easily disassembled and repaired. 2. The snap-fit ​​anti-detachment structure between adjacent mounting pipes enables rapid assembly of the heat exchanger and ensures the sealing and safety of the mounting pipe connection, preventing the mounting pipes from detaching and ensuring stable operation of the heat exchanger.

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses an integrated plate heat exchanger.

[0034] Reference Figure 1 The integrated plate heat exchanger provided in this embodiment includes three mounting pipes 1, which are sequentially connected. The lengths of the three mounting pipes 1 are different, and can be cut to a suitable length according to actual needs. The mounting pipes 1 are commonly made of metals such as stainless steel, which have good corrosion resistance and thermal conductivity, and are mostly cylindrical to provide space for the internal heat exchange components. During installation, the evaporator 2 and the gas-liquid separator 3 are installed in the inner cavity of their respective mounting pipes 1, and the oil separator 4 and the condenser 5 are respectively installed in their respective mounting pipes 1, which can be fixed by bolts, welding, or other methods. The sequential connection of the mounting pipes 1 ensures smooth flow of the medium between the heat exchange components. For example, in a chemical production heat exchange system, the medium flows from the gas-liquid separator 3 through the evaporator 2, oil separator 4, and condenser 5, finally returning to the external compressor, forming a complete heat exchange cycle.

[0035] Reference Figure 1Evaporator 2 can be a common plate evaporator, which features high heat transfer efficiency and compact structure. Alternatively, a tubular evaporator can be used, as it has a simpler structure and lower cost. Gas-liquid separator 3 can be a gravity-type gas-liquid separator, utilizing the difference in gas and liquid density to separate the liquid under gravity. A centrifugal gas-liquid separator can also be used, achieving gas-liquid separation through centrifugal force. Oil separator 4 can be a filter-type oil separator, separating oil through a filter medium, or an inertial oil separator, utilizing the inertia of oil droplets for separation. Condenser 5 can be an air-cooled condenser, offering advantages such as easy installation, or a water-cooled condenser, providing better cooling performance.

[0036] Reference Figure 1 The gas-liquid separator 3, evaporator 2, oil separator 4, and condenser 5 are connected in sequence to form a heat exchange pipeline with the external compressor pipeline. During operation, the refrigerant enters from the external compressor pipeline, first passes through the gas-liquid separator 3 for gas-liquid separation, then enters the evaporator 2 to absorb heat, then enters the oil separator 4 to separate oil, then enters the condenser 5 to release heat, and finally returns to the external compressor pipeline. This cycle is repeated to achieve heat exchange.

[0037] Reference Figure 1 To facilitate convenient assembly and disassembly of the heat exchanger, a snap-fit ​​anti-detachment structure 6 is installed between two adjacent mounting pipes 1. The snap-fit ​​anti-detachment structure 6 is located between two adjacent mounting pipes 1 and is used for quick assembly of the heat exchanger. When the heat exchanger needs to be installed, the adjacent mounting pipes 1 can be quickly joined together using the snap-fit ​​anti-detachment structure 6, effectively preventing detachment during the connection process.

[0038] Reference Figure 2 and Figure 3 Specifically, the snap-fit ​​anti-detachment structure 6 includes a first groove 8, a second groove 9, a clamping and sealing component 10, a clamping and abutting component 11, a flange 12, a third groove 13, and an adjustable connector 14. The first groove 8 and the second groove 9 are formed on the same port of the mounting tube 1. The flange 12 and the third groove 13 are formed on the port of another mounting tube 1. The flange 12 is located on the side of the third groove 13 away from the inner cavity of the mounting tube 1. To facilitate the connection of the two mounting tubes 1, the second groove 9 is connected to the third groove 13, and the second groove 9 is located between the first groove 8 and the inner cavity of the mounting tube 1. When two adjacent mounting tubes 1 are spliced, these flanges 12 are embedded in the first groove 8, and the clamping and abutting component 11 in the second groove 9 cooperates with the adjustable connector 14 in the third groove 13, thereby achieving the functions of quick splicing and anti-detachment.

[0039] Reference Figure 2 and Figure 3Specifically, the clamping and sealing assembly 10 includes an annular bladder 15 and a clamping bladder 16. The annular bladder 15 is installed in the first groove 8 and can be made of rubber, providing good elasticity and sealing performance. The clamping bladder 16 communicates with the annular bladder 15 and includes a U-shaped shell 17 and a flexible layer 18, with the flexible layer 18 formed on the side of the U-shaped shell 17 away from the annular bladder 15. When two adjacent mounting tubes 1 are connected, the flange 12 gradually embeds into the cavity of the flexible layer 18. During this process, the pressure inside the annular bladder 15 is transmitted to the clamping bladder 16, causing the flexible layer 18 to tightly wrap around the flange 12, further enhancing the sealing performance of the connection. The U-shaped shell 17 can be made of plastic, which is lightweight and has a certain strength, while the flexible layer 18 can be made of silicone, which is soft and provides good sealing performance.

[0040] Reference Figure 4 and Figure 5 The clamping and abutting assembly 11 includes a mounting plate 19, a pull rod 20, and a connecting block 21. The mounting plate 19 is fixed by welding or bolts, providing support for the other components. The pull rod 20 can slide on the mounting plate 19 to move the connecting block 21. In this embodiment, to achieve the anti-detachment effect, the mounting plate 19 is provided with a mounting rod 27, a mounting seat 28, a torsion spring 29, an abutting rod 30, and a wedge block 31.

[0041] Reference Figure 4 and Figure 5 The axial direction of the mounting rod 27 is perpendicular to the axial direction of the mounting tube 1. A guide groove 33 is provided on the mounting plate 19 for the mounting rod 27 to slide toward another mounting tube 1. Both ends of the mounting rod 27 slide in the guide groove 33. In order to ensure the stability of the connection between the two mounting tubes 1, when the mounting rod 27 is located at the end of the guide groove 33 away from the other mounting tube 1, the guide groove 33 can only limit the two mounting tubes 1 to slide toward each other.

[0042] Reference Figure 4 and Figure 5 The mounting base 28 is rotatably connected to the mounting rod 27. One end of the torsion spring 29 is fixed to the mounting base 28, and the other end is fixed to the mounting rod 27, thereby achieving the effect of rotating and resetting the mounting base 28. The abutment rod 30 is fixed to the mounting base 28. A through hole 32 is opened between the first groove 8 and the second groove 9. The wedge block 31 slides in the through hole 32. The sliding direction of the wedge block 31 is perpendicular to the axial direction of the mounting tube 1. The end of the abutment rod 30 away from the mounting base 28 abuts against the wedge block 31. In this embodiment, the end of the abutment rod 30 away from the mounting base 28 is set into an arc shape. Thus, when the mounting base 28 rotates, the abutment rod 30 rotates clockwise synchronously and slides against the wedge block 31 in the direction of squeezing the annular bladder 15.

[0043] Reference Figure 5 and Figure 6The adjustable connector 14 includes a telescopic rod 22, a latch 23, and a return spring 24 disposed on the telescopic rod 22. In this embodiment, the end of the pull rod 20 away from the connecting block 21 is fixed to the mounting base 28. The connecting block 21 is frustum-shaped, with the larger diameter end fixed to the pull rod 20, and a slot 25 is provided on the connecting block 21. The frustum shape allows the latch 23 to slide more smoothly along its surface and embed into the slot 25 when it engages with the connecting block 21, avoiding jamming and displacement, and enhancing connection reliability.

[0044] Reference Figure 5 and Figure 6 A groove 26 is formed on the inner wall of the third groove 13. The groove 26 is circular and its length is perpendicular to the axial direction of the mounting tube 1. The telescopic rod 22 is installed in the groove 26 and consists of two sliding tubes. A latch 23 is fixedly installed at the telescopic end of the telescopic rod 22. To ensure that the telescopic end of the telescopic rod 22 is always in the extended state, a return spring 24 is coaxially sleeved at the telescopic end of the telescopic rod 22. One end of the return spring 24 is fixed to the fixed end of the telescopic rod 22, and the other end is fixed to the telescopic end of the telescopic rod 22. A bevel is formed on the side of the latch 23 facing the connecting block 21 to cooperate with the frustum shape of the connecting block 21. When adjacent mounting tubes 1 are connected, the connecting block 21 squeezes the latch 23 to retract. When the latch groove 25 is aligned with the latch 23, the latch 23 is embedded in the latch groove 25 under the action of elastic force to achieve a locking and anti-disengagement.

[0045] Reference Figure 5 and Figure 6 To adjust the pressing force of the adjusting latch 23 on the connecting block 21, the groove 26 is connected to the outer wall of the mounting pipe 1, allowing the entire telescopic rod 22 to slide within the groove 26. An adjusting rod 34 is rotatably connected to the fixed end of the telescopic rod 22. The adjusting rod 34 is threadedly connected to the groove 26, and a prismatic groove 35 is provided at the end of the adjusting rod 34 away from the telescopic rod 22. Rotating the adjusting rod 34 with a prismatic wrench can move the telescopic rod 22, flexibly adjusting the engagement state between the latch 23 and the groove 25.

[0046] Reference Figure 1 In this embodiment, to ensure the stability of the heat exchanger installation, a support assembly 7 for supporting the entire heat exchanger is also provided on the outer wall of part of the installation pipe 1. The support assembly 7 consists of a first support base 36, a second support base 37, and a connecting support 38. The first support base 36 and the second support base 37 are commonly made of high-strength metals such as carbon steel and can be fixed to the installation pipe 1 by welding or bolting. The connecting support 38 can be rod-shaped, with both ends welded or bolted to the support base. The support assembly 7 enhances the stability and structural strength of the integrated plate heat exchanger, ensuring operational reliability.

[0047] Reference Figure 1Specifically, the first support 36 is fixed between one of the mounting pipes 1, the second support 37 is fixed to the outside of the other mounting pipe 1, and the connecting support 38 is disposed between the first support 36 and the second support 37. During the operation of the heat exchanger, the support assembly 7 bears the weight of the heat exchanger and the vibration generated during operation, providing stable support for the heat exchanger and ensuring its normal operation. The connecting support 38 can be made of steel beams or channel steel, etc., serving both a connecting and supporting function.

[0048] The implementation principle of an integrated plate heat exchanger according to an embodiment of this application is as follows: The integrated plate heat exchanger installs the evaporator 2, gas-liquid separator 3, oil separator 4, and condenser 5 in different mounting pipes 1, and achieves rapid assembly through a snap-fit ​​anti-detachment structure 6, which facilitates installation and disassembly and solves the problems of difficult maintenance and poor stability of bolted connections in traditional welding methods. The clamping sealing component 10 in the snap-fit ​​anti-detachment structure 6 ensures the sealing of the connection, the clamping abutment component 11 prevents the connection from detaching, and the support component 7 provides stable support for the heat exchanger, thereby improving the overall performance and operational stability of the heat exchanger.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
