Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and more specifically, to a combined plate heat exchanger. Background Technology
[0002] A modular plate heat exchanger is a highly efficient heat exchange device that uses stacked metal plates to form flow channels, enabling heat transfer between two or more fluids. Its core principle is to increase the heat transfer area by utilizing the surface of the plates, while reducing thermal resistance through turbulent flow between the plates, thereby improving heat transfer efficiency. A modular plate heat exchanger mainly consists of plates, gaskets, a frame, pipes, and interfaces. Among these, the plates are the main components responsible for heat exchange. During the heat exchange process, the hot fluid flows through one side of the plates, and heat is conducted to the cold fluid on the other side via the metal plates. At the same time, the corrugated structure promotes fluid turbulence, disrupts the boundary layer, and enhances heat transfer. The heat transfer area and fluid resistance can be flexibly changed by increasing or decreasing the number of plates or adjusting the flow combination according to the applied heat exchange requirements. Since the plates are thin metal sheets and are located on the outer side during operation, it is necessary to perform combined protective operations on the plates.
[0003] In related technologies, during the use of combined plate heat exchangers, the assembled plates are generally clamped and stabilized inside the frame by means of a frame and bolts to form a heat exchange channel for use.
[0004] However, in the current use of combined plate heat exchangers, the frame is in an open state after the plates are assembled and clamped. When external objects accidentally collide with the plates, the plates are easily deformed by the force, causing the sealing gaskets between the plates to separate, the flow channels to lose their sealing performance, and heat exchange leakage to occur. This affects the stability and protection of the combined plate heat exchanger in combined use. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-4 This utility model provides a technical solution: a combined plate heat exchanger, including a heat exchanger 1 and a combined protective mechanism. Plates 2 are installed inside the heat exchanger 1, and an end plate 3 is installed on the left side of the plate 2. After the heat exchanger 1 and the end plate 3 are combined and installed with the plates 2, the two sides of the plates 2 are covered and protected to prevent external objects from colliding with the plates 2, causing deformation of the inner flow channel of the plates 2 and loss of sealing fluid leakage. Therefore, the stability and protection of the combined use of the plates 2 are improved.
[0031] Reference Figures 1-4 In a preferred embodiment, the combined protective mechanism includes a protective base 4, which is movably connected to the top of the end plate 3. Protective rods 5 are movably connected to both sides of the protective base 4. A protective plate 6 is fixedly connected to the outside of the protective rods 5. A sliding plate 7 is movably connected to the outside of the protective plate 6. The protective connection mechanism is located on the top of the protective base 4. The protective plate 6 is installed on both sides of the end plate 3 by the protective base 4 and the protective rods 5. Then, according to the required protective coverage of the combined plate 2, the sliding plate 7 is moved to the right by hand, so that the protective plate 6, in conjunction with the sliding plate 7, covers and protects the plate 2 that is combined and installed on the inner side of the heat exchanger 1 and the end plate 3. The protective connection mechanism includes a connecting groove 8, a double-ended screw 9, a screw hole 10, and a connecting cavity 11. The connecting groove 8 is located on the top of the protective base 4. The double-ended screw 9 is movably connected inside the connecting groove 8. The screw hole 10 is located on the inner side of the protective rod 5. The double-ended screw 9 is threadedly connected to the protective rod 5 through the screw hole 10. The connecting cavity 11 is located on the outer side of the inner wall of the screw hole 10, which allows for protective adjustment and connection between the protective rod 5 and the protective base 4. This allows the user to adjust the protection range by simultaneously moving the protective rod 5 to move the protective plate 6 according to actual protection needs, thus improving the ease of use of the protective rod 5.
[0032] Reference Figures 2-3In a preferred embodiment, support grooves 12 are provided on both sides of the inner wall of the connecting cavity 11. A support rod 13 is movably connected inside the support groove 12. The inner side of the support rod 13 is fixedly connected to the outer side of the protective seat 4. This allows for adjustment and support between the protective rod 5 and the protective seat 4 to prevent displacement, thus improving the stability of the protective rod 5 during use. A reference plate 14 is fixedly connected to the left side of the bottom of the protective seat 4. The right side of the reference plate 14 contacts the left side of the end plate 3, providing a reference medium for the installation of the protective seat 4 with the end plate 3. This prevents the protective seat 4 from being difficult to install parallel to the top of the end plate 3 during use, thus improving the ease of installation of the protective seat 4.
[0033] Reference Figures 2-4 In a preferred embodiment, a translation opening 15 is provided on the outer side of the translation plate 7, and a translation frame 16 is movably connected inside the translation opening 15. The inner side of the translation frame 16 is fixedly connected to the outer side of the protective plate 6, which can perform translation connection work between the translation plate 7 and the protective plate 6, avoiding positional deviation of the translation plate 7 during use. Therefore, the translation connection effect between the translation plate 7 and the protective plate 6 is improved. A magnetic strip 17 is embedded in the top of the inner wall of the translation opening 15, and a magnetic suction piece 18 magnetically connected to the magnetic strip 17 is embedded in the top of the translation frame 16. The translation frame 16 can perform magnetic pre-positioning work between the translated protective plate 6 and the translation plate 7, thus improving the ease of operation of the translation plate 7.
[0034] Reference Figures 2-4 In a preferred embodiment, a clamping frame 19 is movably connected to the outside of the translation frame 16, and a clamping pad 20 is fixedly connected to the inside of the clamping frame 19. The translation frame 16 can be used to clamp and fix the adjusted protective plate 6 and the translation plate 7, thus improving the convenience of fixing the translation plate 7. A screw groove 21 is provided on the inside of the clamping frame 19, and a stud 22 is threaded inside the screw groove 21. The inside of the stud 22 is fixedly connected to the outside of the translation frame 16, which can provide a medium for the clamping frame 19 to apply clamping force when connected to the translation frame 16, thus improving the clamping effect of the clamping frame 19.
[0035] Specifically, the working process or principle of this combined plate heat exchanger is as follows: During use, after the plates 2 are assembled and installed inside the heat exchanger 1 and the end plate 3, and clamped and secured to the end plate 3 and both sides of the heat exchanger 1 with bolts, the protective seat 4 is moved to the top of the end plate 3, with the protective plate 6 positioned on the right side of the outer side of the end plate 3, and the right side of the reference plate 14 in contact with the left side of the end plate 3, ensuring that the protective seat 4 is parallel to the top of the end plate 3. Then, the double-ended screw is rotated through the connecting groove 8 on the top of the protective seat 4. When rapid rotation of the double-ended screw 9 is required, the externally placed strip inside the connecting groove 8 on top of the protective seat 4 can be held and brought into contact with the double-ended screw 9. The double-ended screw 9 can be rapidly rotated by the translation plate 7. As the double-ended screw 9 rotates and engages with the screw hole 10, the double-ended screw 9 applies an inward threaded thrust to the protective plate 6 through the protective rod 5, causing the inner side of the protective plate 6 to contact and abut against the outer side of the end plate 3, clamping and installing the protective plate 6 on the outer side of the end plate 3. At this time, the support rod 13 supports... The support groove 12 moves internally to perform translational support connection between the protective rod 5 and the protective seat 4, ensuring stability during the process of the double-headed screw 9 pushing the protective rod 5. Then, according to the actual coverage area requirement of the plate 2, the handheld translation plate 7 is moved to the right to perform translational expansion operation on the coverage area of the protective plate 6. At this time, the translation frame 16 moves internally within the translation port 15 to perform translational connection between the translation plate 7 and the protective plate 6. Simultaneously, the magnetic strip 17 cooperates with the magnetic suction piece 18 to perform translational connection. The frame 16 performs magnetic pre-positioning between the translated protective plate 6 and the translation plate 7. After the translation plate 7 is adjusted, the hand-held clamping frame 19 drives the screw groove 21 to rotate, so that the stud 22 cooperates with the screw groove 21 to apply an inward threaded thrust to the clamping frame 19, so that the clamping frame 19 drives the clamping pad 20 to contact and press against the translation plate 7. This performs a pressing and fixing operation between the translation plate 7 and the protective plate 6 after the adjustment operation, so that the protective plate 6 cooperates with the translation plate 7 to stably cover and protect the plate 2.
[0036] It should be noted that heat exchanger 1, plate 2 and end plate 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
