[0033] Refer to Figures 1 to 4, the present invention provides a modular heat exchanger, which includes a frame assembly 1 and a plurality of channel plates 2. The frame assembly 1 includes an upper frame plate 11 and a lower frame plate 12. An upper docking hole 111 is formed on the upper frame plate 11, and a lower docking hole 121 is formed on the lower frame plate 12. The plurality of channel plates 2 are arranged between the upper frame plate 11 and the lower frame plate 12. Channel holes 21, a first sealing groove 22 and a second sealing groove 23 are formed on the channel plates 2. The upper docking hole 111 and the lower docking hole 121 are both arranged corresponding to the positions of the channel holes 21, so that the upper docking hole 111, the lower docking hole 121 and the channel holes 21 communicate with each other. The first sealing groove 22 is arranged around the outer edge of the channel holes 21, and the second sealing groove 23 is arranged around the outer edge of the channel plates 2.
[0034] In this embodiment, the upper frame plate 11, the lower frame plate 12 and the channel plates 2 have the same size. The channel plates 2 are fixedly connected to the upper frame plate 11 and the lower frame plate 12 by brazing. The upper docking hole 111, the lower docking hole 121 and the channel holes 21 are all circular holes. When the upper frame plate 11, the lower frame plate 12 and the channel plates 2 are fixedly connected, the upper docking hole 111, the lower docking hole 121 and the channel holes 21 are coaxially arranged to form a channel for fluid to pass through. Four channel holes 21 are formed on the channel plates 2. The upper docking hole 111 and the lower docking hole 121 are both arranged in one-to-one correspondence with the channel holes 21. The first sealing groove 22 is arranged in one-to-one correspondence with the channel holes 21 and is concentric with the channel holes 21. Sealing rings (not shown in the figure) adapted to them are arranged in both the first sealing groove 22 and the second sealing groove 23 to achieve the sealing between the channel plates 2 and the sealing between the channel plates 2 and the upper frame plate 11 or the lower frame plate 12.
[0035] In this way, a frame assembly 1 and its corresponding connected channel plates 2 form a module. Connecting multiple modules can increase the scale of the modular heat exchanger. The combination is more flexible, can adapt to different working conditions and usage scenarios, thus meeting different requirements and improving the flexibility of the modular heat exchanger. During use, even if a single module fails, it can be quickly disassembled and replaced, reducing the scrap cost and production cost and improving the working efficiency of the entire system. By setting the first sealing groove 22 and the second sealing groove 23, double sealing can be achieved, reducing the risk of fluid leakage and improving the sealing performance and safety of the modular heat exchanger.
[0036] It can be understood that the number of channel plates 2 between the same group of frame assemblies 1 can be adjusted according to actual needs. By increasing or decreasing the number of channel plates 2, the overall size and heat exchange efficiency of the modular heat exchanger can be adjusted, and it is only necessary to enable heat exchange between the hot fluid and the cold fluid, which will not be elaborated here.
[0037] Furthermore, the frame component 1 further includes a connecting member (not shown in the figure), and the connecting member is connected to the upper frame plate 11, the lower frame plate 12, and the channel plate 2 to limit the relative positions between the upper frame plate 11, the lower frame plate 12, and the channel plate 2.
[0038] It can be understood that the connecting member can be a bolt or a connecting rod, and the specific structure of the connecting member can be adjusted according to actual needs and will not be listed in detail here.
[0039] It should be noted that the hot fluid and the cold fluid flow in the upper docking hole 111 and the lower docking hole 121 respectively, and the heat exchange between the hot fluid and the cold fluid is realized through the channel holes 21 between multiple channel plates 2, which is a prior art and will not be elaborated here.
[0040] Refer to Figure 2 , in some embodiments, a first detection hole 24 and a second detection hole 25 are further formed on the channel plate 2. The first detection hole 24 communicates with the first sealing groove 22, and the second detection hole 25 communicates with the second sealing groove 23.
[0041] In this embodiment, the first detection holes 24 and the first sealing grooves 22 are arranged in one-to-one correspondence. That is, there are four first detection holes 24. The upper frame plate 11 is provided with first upper detection holes 112 at positions corresponding to the first detection holes 24, and the lower frame plate 12 is provided with first lower detection holes 122 at positions corresponding to the first detection holes 24, so that the first upper detection holes 112, the first detection holes 24, and the first lower detection holes 122 corresponding to the same channel hole 21 communicate with each other; there is one second detection hole 25. The upper frame plate 11 is provided with a second upper detection hole 113 at a position corresponding to the second detection hole 25, and the lower frame plate 12 is provided with a second lower detection hole 123 at a position corresponding to the second detection hole 25, so that the second upper detection hole 113, the second detection hole 25, and the second lower detection hole 123 communicate with each other, facilitating the leak detection probe to extend into the first detection hole 24 and the second detection hole 25.
[0042] In this way, by providing the first detection holes 24 corresponding to the first sealing grooves 22 and the second detection holes 25 corresponding to the second sealing grooves 23 on the channel plate 2, it is convenient for the staff to detect the sealing state of the modular heat exchanger after assembly by inserting the probe into the first detection hole 24 and the second detection hole 25, ensuring the reliability of the sealing performance, avoiding leakage and resulting in system failures, improving the efficiency of the leak detection operation, facilitating the staff to perform on-site maintenance, and facilitating quickly locating the specific module with leakage and replacing it in time to ensure normal production work.
[0043] It can be understood that the number and the setting positions of the first detection holes 24 and the second detection holes 25 can be adjusted according to actual needs and will not be listed in detail here.
[0044] It should be noted that detecting the sealing performance of the edge of the channel plate 2 and the positions where the channel holes 21 are provided on the channel plate 2 by inserting a probe is a prior art. The leak detection method can be the helium leak detection method or the ultrasonic flaw detection method, and the leak detection method can be adjusted according to actual needs.
[0045] Refer to Figure 2 , in some embodiments, a first connection groove 26 and a second connection groove 27 are further provided on the channel plate 2. Two ends of the first connection groove 26 are respectively communicated with the first sealing groove 22 and the first detection hole 24, and two ends of the second connection groove 27 are respectively communicated with the second sealing groove 23 and the second detection hole 25.
[0046] In this embodiment, the first connection groove 26 extends along the length direction of the channel plate 2, the second connection groove 27 extends along the width direction of the channel plate 2, the first connection groove 26 and the first detection hole 24 are arranged in one-to-one correspondence, and the second connection groove 27 and the second detection hole 25 are arranged in correspondence.
[0047] In this way, the first detection hole 24 and the first sealing groove 22 are connected through the first connection groove 26, and the second detection hole 25 and the second sealing groove 23 are connected through the second connection groove 27, which can set the first detection hole 24 and the second detection hole 25 at reasonable positions. While the detection probe can detect the sealing states of the channel holes 21 and the edge of the channel plate 2 through the first detection hole 24 and the second detection hole 25, the first detection hole 24 and the second detection hole 25 are not likely to interfere with structures such as the first sealing groove 22, the second sealing groove 23, and the corrugations 28 provided on the channel plate 2, rationally utilizing the space of the channel plate 2, making the overall structure of the modular heat exchanger more compact, and improving the adaptability under different working conditions and usage scenarios.
[0048] It can be understood that the length directions of the first connection groove 26 and the second connection groove 27 can both be adjusted according to actual needs, and no more examples are listed here.
[0049] Refer to Figure 2 , in some embodiments, the axis of the second connection groove 27 coincides with the axis in the width direction of the channel plate 2.
[0050] In this embodiment, the four channel holes 21 are symmetrically arranged along the length direction of the channel plate 2. Correspondingly, the first sealing groove 22, the first connection groove 26, and the first detection hole 24 are all symmetrically arranged along the length direction of the channel plate 2.
[0051] In this way, the first connection groove 26, the second connection groove 27, the first detection hole 24, and the second detection hole 25 are evenly spaced on the channel plate 2, which can enable the channel plate 2 to have sufficient structural strength, evenly disperse external forces, and avoid local stress concentration, ensuring that after multiple modules are connected, the modular heat exchanger has sufficient stability and durability, and reducing production costs.
[0052] Refer to Figure 2 Figure 2 , in some embodiments, a plurality of channel holes 21 are provided, and the first detection holes 24 are provided in one-to-one correspondence with the channel holes 21. Along the length direction of the channel plate 2, the first detection holes 24 corresponding to adjacent channel holes 21 are arranged facing each other.
[0053] In this embodiment, corrugations 28 are provided on the channel plate 2. Four channel holes 21 are symmetrically arranged on both sides of the corrugations 28, and the first detection holes 24 are arranged at one end of the first connection groove 26 away from the corresponding channel hole 21, that is, the first detection holes 24 are arranged facing the corrugations 28.
[0054] In this way, the corrugations 28 can guide the flow of the fluid, increase the heat exchange area, and improve the heat exchange efficiency. The first detection holes 24 are arranged facing the corrugations 28, which enables the detection probe to detect the position of the channel plate 2 close to the corrugations 28 in a timely manner, facilitating the staff to quickly discover and locate the position with poor sealing, facilitating on-site disassembly and replacement, shortening the maintenance time, reducing the maintenance cost, and improving the reliability and safety of the modular heat exchanger.
[0055] It can be understood that the number and arrangement position of the channel holes 21, and the direction and arrangement position of the corrugations 28 can all be adjusted according to actual needs, and will not be listed in detail here.
[0056] Refer to Figures 5 to 7 Figures 5 to 7 , in some embodiments, multiple sets of frame components 1 are provided, and the multiple sets of frame components 1 are arranged along the thickness direction of the channel plate 2.
[0057] In this embodiment, refer to Figure 5 and Figure 6 Figure 6 , in adjacent frame components 1, the upper frame plate 11 of one set of frame components 1 is fixedly connected to the lower frame plate 12 of another set of frame components 1, so that multiple modules are fixedly connected and combined into a modular heat exchanger.
[0058] In this way, by connecting multiple sets of frame components 1 in series, the flexibility of the modular heat exchanger can be improved. Even if one module fails, it can be replaced in time with a new module, enabling the system to continue production, reducing the maintenance and scrap costs, and by different combinations, the heat exchange efficiency of the modular heat exchanger can be adjusted according to different working conditions and usage scenarios, meeting various industrial requirements, improving the reliability and safety of the modular heat exchanger, and extending the service life of the modular heat exchanger.
[0059] It can be understood that the number of frame components 1 can be adjusted according to actual needs, and the number of channel plates 2 corresponding to each frame component 1 can be the same or different. The number of frame components 1 and the number of channel plates 2 corresponding to each group of frame components 1 can be adjusted according to actual production needs, and no further examples will be given here.
[0060] See also Figure 5 and Figure 6 In some embodiments, adjacent frame assemblies 1, the upper frame plate 11 of one group of frame assemblies 1 is docked with the lower frame plate 12 of another group of frame assemblies 1, the outer edge of the upper frame plate 11 is sealed with the outer edge of the lower frame plate 12, and the position where the upper docking hole 111 is set on the upper frame plate 11 is sealed with the position where the lower docking hole 121 is set on the lower frame plate 12.
[0061] In this embodiment, the outer edge of the upper frame plate 11 and the outer edge of the lower frame plate 12 are fixedly sealed and connected by brazing, and the position where the upper docking hole 111 is set on the upper frame plate 11 and the position where the lower docking hole 121 is set on the lower frame plate 12 are fixedly sealed and connected by brazing.
[0062] In this way, after large-scale production of individual modules, the modules are sealed and connected through two welding processes, which can improve the sealing performance between the adjacent upper frame plates 11 and lower frame plates 12 and improve the assembly efficiency. By increasing or decreasing the number of modules or adjusting a single module as needed, a modular heat exchanger that can adapt to different working conditions and usage scenarios can be combined.
[0063] It can be understood that the adjacent upper frame plates 11 and lower frame plates 12 can also be sealed and connected by means of rubber strip sealing, pull rod locking, etc., and are not limited to brazing. The connection method between the upper frame plate 11 and the lower frame plate 12 can be adjusted according to actual needs. In this embodiment, brazing is used to improve the connection strength between the modules.
[0064] See also Figure 6 and Figure 7 In some embodiments, a solder groove 114 is provided on a side of the upper frame plate 11 facing away from the channel plate 2 . The solder groove 114 is coaxially arranged with the upper docking hole 111 and communicated with the upper docking hole 111 .
[0065] In this embodiment, when one of the upper frame plates 11 and the lower frame plate 12 in the adjacent frame assemblies 1 are docked, the solder groove 114 is located between the upper docking hole 111 and the lower docking hole 121, so as to seal and connect the position where the upper docking hole 111 of the upper frame plate 11 is set and the position where the lower docking hole 121 of the lower frame plate 12 is set.
[0066] Thus, when the channel hole 21 is not applicable to internal welding, filling the solder in the solder bath 114 and performing brazing on the upper frame plate 11 and the lower frame plate 12 can achieve the sealed connection of the upper frame plate 11 and the lower frame plate 12, facilitate the combined connection of multiple modules, improve the installation efficiency, and enable the modular heat exchanger to adapt to different working conditions and usage scenarios, enhancing the flexibility and reliability of the modular heat exchanger.
[0067] Referring to Figure 5 , in some embodiments, the aperture of the lower docking hole 121 is greater than or equal to the aperture of the upper docking hole 111.
[0068] In this embodiment, the apertures of the upper docking hole 111 and the lower docking hole 121 are both greater than or equal to the aperture of the channel hole 21, so that the hot fluid and the cold fluid can flow in the upper docking hole 111, the channel hole 21, and the lower docking hole 121.
[0069] Thus, when the adjacent upper frame plate 11 and the lower frame plate 12 are docked, since the aperture of the lower docking hole 121 is greater than or equal to the aperture of the upper docking hole 111, sufficient welding space can be provided, facilitating the welding of the positions where the upper docking hole 111 is set on the upper frame plate 11 and the position where the lower docking hole 121 is set on the lower frame plate 12 by the staff, facilitating the combined connection of multiple modules to form a modular heat exchanger, and enabling the size of the modular heat exchanger to be adjusted according to actual needs, enhancing the flexibility and reliability of the modular heat exchanger.
[0070] It can be understood that the apertures of the upper docking hole 111 and the lower docking hole 121 can be adjusted according to the aperture of the channel hole 21, which will not be elaborated here.
[0071] Referring to Figure 8 , the present invention also provides a combination method for combining a modular heat exchanger. The combination method includes:
[0072] S1. Assembling the frame assembly 1 and the channel plate 2, and fixedly arranging the channel plate 2 between the upper frame plate 11 and the lower frame plate 12 of the same group of frame assemblies 1;
[0073] S2. Aligning adjacent frame assemblies 1, and aligning the upper docking hole 111 and the lower docking hole 121 of the upper frame plate 11 of one group of frame assemblies 1 with the lower frame plate 12 of its adjacent group of frame assemblies 1;
[0074] S3. Fixing and connecting adjacent frame assemblies 1, so that the outer edges of the upper frame plate 11 and the lower frame plate 12 are sealedly connected, and the positions where the upper docking hole 111 is opened on the upper frame plate 11 and the positions where the lower docking hole 121 is opened on the lower frame plate 12 are sealedly connected;
[0075] S4. Detect the sealing performance. Insert the detection probe into the first detection hole 24 and the second detection hole 25 to detect the sealing performance of the edge of the channel hole 21 and the channel plate 2.
[0076] In step S1, after the channel plate 2 is fixedly arranged on the upper frame plate 11 and the lower frame plate 12, the first upper detection hole 112, the first detection hole 24, and the first lower detection hole 122 are communicated; the second upper detection hole 113, the second detection hole 25, and the second lower detection hole 123 are communicated; the upper docking hole 111, the channel hole 21, and the lower docking hole 121 are communicated.
[0077] In step S3, weld the joint of the outer edges of the upper frame plate 11 and the lower frame plate 12 that are aligned with each other, and insert the welding torch into the joint of the upper docking hole 111 and the lower docking hole 121 for welding. Or, when it is not convenient for the welding torch to insert into the upper docking hole 111 and the lower docking hole 121, open a filler metal groove 114 on the upper frame plate 11 and fill it with filler metal, so that the position of the upper docking hole 111 on the upper frame plate 11 and the position of the lower docking hole 121 on the lower frame plate 12 are hermetically connected by brazing.
