Description

Technical Field

[0001] This application relates to the field of multi-channel stratified heat exchanger technology, and in particular to a multi-channel stratified heat exchanger with a corrugated baffle. Background Technology

[0002] In the field of compact heat exchange equipment, such as automotive radiators and air conditioning systems, the optimization design of flow channel structure has always been a research focus. With the increasing trend of equipment miniaturization, the structural limitations of traditional heat exchangers are becoming more and more prominent. At present, the mainstream research direction focuses on enhancing the turbulence effect by changing the geometry of the flow channel, while controlling the pressure drop within a reasonable range. Microchannel technology and layered flow channel design have become the main technical routes to improve the heat exchange efficiency per unit volume. However, existing solutions often fail to achieve an ideal balance between manufacturing process complexity and the actual improvement in heat exchange performance.

[0003] In existing layered flow channel designs, each layer of the flow channel often uses the same turbulence structure, which cannot adapt to the different physical properties of hot and cold fluids, and easily leads to the problem of low local heat exchange efficiency. Utility Model Content

[0004] The purpose of this application is to provide a multi-channel layered heat exchanger with a corrugated baffle, which has the advantages of low resistance and high heat transfer efficiency, and is a purely mechanical heat exchanger. It solves the problem that in the existing layered flow channel design, each flow channel often adopts the same baffle structure, which cannot adapt to different physical properties of hot and cold fluids and is prone to local low heat transfer efficiency.

[0005] This application provides a multi-channel stratified heat exchanger with corrugated baffles, employing the following technical solution: It includes a frame, the inner wall of which is provided with several grooves; the interior of the frame is provided with several support plates and flow channel partition plates; the outer surface of each flow channel partition plate is provided with a flow channel groove; the outer surface of each flow channel partition plate is fixedly connected to a corresponding support plate; the outer surface of each support plate is slidably connected to a corresponding groove; the interior of the frame is provided with several corrugated baffles, the outer surface of each corrugated baffle being fixedly connected to a corresponding flow channel partition plate.

[0006] By adopting the above technical solution, the frame serves as the basic framework, and the grooves on its inner wall provide a sliding track for the support plate. This design facilitates the disassembly and maintenance of the support plate and the flow channel partition plate fixedly connected to it, and makes it convenient for later inspection or replacement of internal components. The flow channel grooves on the outer surface of the flow channel partition plate are key channels for medium flow. The setting of the flow channel partition plate achieves the effect of multi-channel layering. The flow channel grooves serve as flow channels for hot and cold fluids. The multi-channel layering design improves the uniformity of the flow field and the utilization rate of the heat exchange area. At this time, different media flow in different channels, increasing the heat exchange contact area. The wavy line turbulence plate is fixedly connected to the flow channel partition plate. Its wavy structure can generate turbulence on the flowing medium. This turbulence can break the laminar boundary layer that may be formed when the medium flows, enhance the turbulence of the medium, thereby improving the heat transfer coefficient between media and thus improving the heat exchange efficiency of the entire heat exchanger.

[0007] Preferably, several support frames are fixedly installed on both sides of the frame, and several slots are opened on both sides of the frame.

[0008] By adopting the above technical solution, the fixed installation of the support frame mainly provides a stable support foundation for the equipment. During the operation of the heat exchanger, various media circulate inside, and the whole has a certain weight. The support frame can stably support the frame on the installation surface, avoiding overall displacement or tilting caused by the equipment's own weight or vibration generated by the flow of media, thus ensuring the stability and safety of the equipment operation. At the same time, it is also convenient to fix and connect the heat exchanger to other equipment or installation platforms.

[0009] Preferably, the outer side of the frame is provided with several fixing plates, and two insert rods are fixedly connected to the outer surface of each fixing plate. The outer surface of each insert rod is slidably connected to the frame, and the outer surface of each fixing plate is slidably connected to the corresponding support frame.

[0010] By adopting the above technical solution, the fixing plate is slidably connected to the frame via a plug rod, and simultaneously slidably engages with the support frame, forming an adjustable auxiliary fixing structure. The plug rod inserted into the frame can position the fixing plate, while the sliding connection with the support frame allows the fixing plate to be adjusted along the extension direction of the support frame, thereby adapting to different installation scenarios or connection requirements with external equipment.

[0011] Preferably, each of the support plates has a slot on its outer surface, and the outer surface of each slot is inserted into a corresponding rod.

[0012] By adopting the above technical solution, the support plate can be fixed by inserting the plug rod into the corresponding slot.

[0013] Preferably, each of the insert rods has a spring sleeved on its outer surface, and one end of each spring near the frame is fixedly connected to the corresponding insert rod, while the other end is fixedly connected to the corresponding support frame.

[0014] By adopting the above technical solution, the corresponding insertion rod is slid out of the frame by pulling the fixing plate. During this process, the spring is compressed. By releasing the fixing plate, the spring will push the corresponding insertion rod to reset under its rebound force, which further improves the assembly adaptability.

[0015] Preferably, the inner wall of each of the fixed plates is rotatably connected to two push plates, and the outer surface of each push plate engages with a corresponding slot.

[0016] By adopting the above technical solution, during installation, simply rotate the push plate to align with the slot and snap it in to complete the connection and fixation between the fixing plate and the frame. During disassembly, simply rotate the push plate out of the slot to easily separate the fixing plate from the frame. Compared with other complicated fixing methods, this greatly improves the efficiency of installation and disassembly, and facilitates the later inspection, cleaning or replacement of the internal components of the heat exchanger.

[0017] Preferably, the frame has inlets and outlets on both the upper and lower sides, and the inner wall of each inlet and outlet is fixedly connected with a sealing pipe.

[0018] By adopting the above technical solution, the upper and lower distributed inlets and outlets can correspond to the inlet and outlet of the layered flow channels. For example, the upper flow channel can be connected to the hot fluid through the top inlet and outlet, and the lower flow channel can be connected to the cold fluid through the bottom inlet and outlet, or vice versa. This ensures that media of different temperatures flow in a directional manner in independent flow channels, avoids cross-flow, and provides a basis for efficient heat exchange. The sealing pipe is fixedly connected to the inner wall of the inlet and outlet and serves as a transitional seal for the connection between the inlet and outlet and the external pipeline, improving the assembly compatibility of the equipment and the pipeline system.

[0019] Preferably, a mounting bracket is fixedly installed on the bottom surface of the frame, the outer surface of the mounting bracket is provided with a mounting groove, the outer surface of the frame is hinged with a mounting door, and the outer surface of the mounting door is provided with an observation window.

[0020] By adopting the above technical solutions, the mounting bracket can directly bear the overall weight of the heat exchanger, distribute the force at the bottom, and prevent the equipment from tilting due to the shift of the center of gravity or vibration. It is especially suitable for vertical installation scenarios, ensuring the structural stability of long-term operation. The mounting slot can be bolted to the ground mounting foundation to achieve precise positioning and fixation, adapting to different on-site installation conditions. The mounting door, as an openable structure of the frame, is equipped with an observation window, which facilitates the inspection and observation of the internal components and their operating status.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This multi-channel layered heat exchanger with a corrugated baffle plate is designed with components such as a frame, chute, support plate, channel partition plate, channel groove, and corrugated baffle plate. The support plate with the corrugated baffle plate and channel partition plate is slid horizontally into the chute for quick installation. It generates periodic disturbances during fluid flow, enhancing mixing and heat transfer. Hot and cold fluids flow cross-flow in alternating channel layers. The corrugated structure increases contact time and turbulence intensity. Through the combination of the corrugated baffle plate and the layered design, a low-resistance, high-heat-transfer-efficiency purely mechanical heat exchange effect is achieved.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A multi-channel stratified heat exchanger with corrugated baffles, referring to... Figure 2 , Figure 3 , Figure 5 The system includes a frame 1, the inner wall of which is provided with several grooves 2, the interior of which is provided with several support plates 9 and flow channel partition plates 10, the outer surface of each flow channel partition plate 10 is provided with a flow channel groove 11, the outer surface of each flow channel partition plate 10 is fixedly connected to the corresponding support plate 9, the outer surface of each support plate 9 is slidably connected to the corresponding groove 2, and the interior of the frame 1 is provided with several wavy line baffle plates 12, the outer surface of each wavy line baffle plate 12 is fixedly connected to the corresponding flow channel partition plate 10.

[0026] like Figure 2 , Figure 3, Figure 5 The frame 1 serves as the basic framework, and the groove 2 on its inner wall provides a sliding track for the support plate 9. This design facilitates the disassembly and maintenance of the support plate 9 and the flow channel partition plate 10 fixedly connected to it, and makes it convenient for later inspection or replacement of internal components. The flow channel groove 11 on the outer surface of the flow channel partition plate 10 is a key channel for medium flow. The setting of the flow channel partition plate 10 realizes the effect of multi-channel layering. The flow channel groove 11 serves as a flow channel for hot and cold fluids. The multi-channel layering design improves the uniformity of the flow field and the utilization rate of the heat exchange area. At this time, different media flow in different channels, increasing the heat exchange contact area. The wavy line turbulence plate 12 is fixedly connected to the flow channel partition plate 10. Its wavy structure can generate turbulence on the flowing medium. This turbulence can break the laminar boundary layer that may be formed when the medium flows, enhance the turbulence of the medium, thereby improving the heat transfer coefficient between media and thus improving the heat exchange efficiency of the entire heat exchanger.

[0027] Example 2: A multi-channel stratified heat exchanger with corrugated baffles, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 Several support frames 3 are fixedly installed on both sides of the frame 1. Several slots 6 are opened on both sides of the frame 1. The fixed installation of the support frames 3 mainly provides a stable support foundation for the equipment. During the operation of the heat exchanger, various media flow inside, and the whole will have a certain weight. The support frames 3 can stably support the frame 1 on the installation surface, avoiding the overall displacement or tilting caused by the weight of the equipment or the vibration caused by the flow of media, ensuring the stability and safety of the equipment operation. At the same time, it is also convenient to fix and connect the heat exchanger to other equipment or installation platforms.

[0028] Please refer to the figure. The outer side of the frame 1 is provided with several fixing plates 4. Two insert rods 7 are fixedly connected to the outer surface of each fixing plate 4. The outer surface of each insert rod 7 is slidably connected to the frame 1, and the outer surface of each fixing plate 4 is slidably connected to the corresponding support frame 3. The fixing plate 4 is slidably connected to the frame 1 via the insert rods 7, and simultaneously slidably engages with the support frame 3, forming an adjustable auxiliary fixing structure. The insert rods 7, inserted into the frame 1, can position the fixing plate 4, while the slidable connection with the support frame 3 allows the fixing plate 4 to adjust its position along the extension direction of the support frame 3, thereby adapting to different installation scenarios or connection requirements with external equipment.

[0029] Please see Figure 4 , Figure 5 Each support plate 9 has a slot 13 on its outer surface. The outer surface of each slot 13 is inserted into the corresponding rod 7. The support plate 9 can be fixed by inserting the rod 7 into the corresponding slot 13.

[0030] Please see Figure 4Each insertion rod 7 has a spring 8 fitted on its outer surface. One end of each spring 8 near the frame 1 is fixedly connected to the corresponding insertion rod 7, and the other end is fixedly connected to the corresponding support frame 3. By pulling the fixing plate 4, the corresponding insertion rod 7 is slid out of the frame 1. During this process, the spring 8 is compressed. By releasing the fixing plate 4, the spring 8 will push the corresponding insertion rod 7 to reset under its rebound force, further improving the assembly adaptability.

[0031] Please see Figure 3 , Figure 4 Each fixed plate 4 has two push plates 5 rotatably connected to its inner wall. The outer surface of each push plate 5 is engaged with the corresponding slot 6. During installation, simply rotate the push plate 5 to align with the slot 6 and engage it to complete the connection and fixation between the fixed plate 4 and the frame 1. During disassembly, simply rotate the push plate 5 out of the slot 6 to easily separate the fixed plate 4 from the frame 1. Compared with other complex fixing methods, this greatly improves the efficiency of installation and disassembly, and facilitates the later inspection, cleaning or replacement of the internal components of the heat exchanger.

[0032] Please see Figure 1 , Figure 2 , Figure 3 The frame 1 has inlet and outlet 14 on both the upper and lower sides. Each inlet and outlet 14 has a sealing pipe 15 fixedly connected to its inner wall. The upper and lower distributed inlet and outlet 14 can correspond to the inlet and outlet of the layered flow channel. For example, the upper flow channel can be connected to the hot fluid through the top inlet and outlet 14, and the lower flow channel can be connected to the cold fluid through the bottom inlet and outlet 14, or vice versa. This ensures that the medium at different temperatures flows in a directional manner in the independent flow channel, avoids cross-flow, and provides a basis for efficient heat exchange. The sealing pipe 15 is fixedly connected to the inner wall of the inlet and outlet 14 and is a transition seal for the connection between the inlet and outlet 14 and the external pipeline, improving the assembly compatibility of the equipment and the pipeline system.

[0033] Please see Figure 1 , Figure 2 , Figure 3 A mounting bracket 16 is fixedly installed on the bottom surface of the frame 1. The outer surface of the mounting bracket 16 has a mounting groove 19. The outer surface of the frame 1 is hinged with a mounting door 17. The outer surface of the mounting door 17 has an observation window 18. The mounting bracket 16 can directly bear the overall weight of the heat exchanger, distribute the force at the bottom, and prevent the equipment from tilting due to the shift of the center of gravity or vibration. It is especially suitable for vertical installation scenarios, ensuring the structural stability of long-term operation. The mounting groove 19 can be bolted to the ground installation foundation to achieve precise positioning and fixation, adapting to different on-site installation conditions. The mounting door 17, as an openable structure of the frame 1, together with the observation window 18, facilitates the inspection and observation of the internal components and operating status.

[0034] The implementation principle of this application embodiment is as follows: First, push the push plate 5 to rotate around the fixed plate 4 until it is engaged in the corresponding slot 6. During this process, the push plate 5 will push the fixed plate 4 to drive the corresponding insertion rod 7 to slide out from the frame 1. Then, the support plate 9 with the wavy line baffle plate 12 and the flow channel partition plate 10 can be slid horizontally into the slide groove 2 to quickly install the support plate 9 until the slot 13 and the corresponding insertion rod 7 are on the same central axis. At this time, by pushing the push plate 5 out of the corresponding slot 6, the spring 8 will push the corresponding insertion rod 7 into the corresponding slot 13 under its rebound force, so as to facilitate the quick fixation of the support plate 9. The wave height and wavelength of the wavy line baffle plate 12 are designed according to the fluid characteristics, which can generate periodic disturbances when the fluid flows, enhance mixing and heat transfer, and allow cold and hot fluids to flow cross-flow in the alternating flow channel layer. The wave structure increases the contact time and turbulence intensity. Through the combination of the wavy line baffle plate 12 and the layered design, a pure mechanical heat exchange effect with low resistance and high heat transfer efficiency is achieved.
