Novel dead angle and scale prevention heat exchanger

Abstract

This utility model discloses a novel heat exchanger designed to prevent scale buildup in dead corners. It includes an outer casing plate with a support bracket fixedly connected to its lower end. A heat exchange assembly is housed within the outer casing plate, and flow inlet / outlet components are connected to the surface of the outer casing plate via the heat exchange assembly. A spiral flow channel is formed by the intersecting arrangement of a first and second heat exchange vortex plate, reducing fluid stagnation areas and lowering the risk of scale buildup. The hollow structure of the vortex plate further optimizes fluid distribution, preventing impurity deposition caused by excessively slow local flow rates. The intersecting arrangement of the double vortex plates expands the heat exchange area, while the counter-current flow of hot and cold fluids improves heat transfer efficiency. The disassembly components (connecting flanges and cover plates) at both ends of the outer casing plate allow for quick opening of the heat exchanger, facilitating cleaning of the internal vortex plates and inspection of the flow channel. Compared to traditional fixed structures, maintenance does not require complete disassembly, saving time and labor costs.

Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a novel heat exchanger that prevents scale buildup in dead corners. Background Technology

[0002] Traditional heat exchangers, due to their poor flow channel design, are prone to scale buildup in corners and welds during long-term use, leading to decreased heat exchange efficiency and even pipe blockage. Furthermore, maintenance of traditional heat exchangers typically requires complete disassembly, which is complex, time-consuming, and increases maintenance costs. In existing technologies, some heat exchangers employ single-circulation flow channels or fixed structures, making it difficult to simultaneously address the needs for scale prevention and convenient maintenance. Therefore, those skilled in the art have proposed a novel heat exchanger designed to prevent scale buildup in dead corners, thereby solving the problems mentioned in the background section. Summary of the Invention

[0003] The purpose of this invention is to provide a novel heat exchanger that prevents fouling in dead corners, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel heat exchanger for preventing scale buildup in dead corners includes an outer casing plate. A support bracket is fixedly connected to the lower end of the outer casing plate. A heat exchange assembly is disposed inside the outer casing plate. A flow inlet / outlet assembly is connected to the surface of the outer casing plate through the heat exchange assembly. The heat exchange assembly includes a first heat exchange vortex plate and a second heat exchange vortex plate. The first heat exchange vortex plate and the second heat exchange vortex plate are fixedly connected inside the outer casing plate. The first heat exchange vortex plate and the second heat exchange vortex plate are arranged to cross each other, and both the first heat exchange vortex plate and the second heat exchange vortex plate are hollow inside.

[0006] Furthermore, the flow inlet / outlet component includes a first hot water outlet, a first cold water outlet, a first connecting plate, a second connecting plate, and a first hot water inlet. One end of the outer casing is fixedly connected to the first hot water outlet, and the other end of the outer casing is fixedly connected to the first cold water inlet.

[0007] Furthermore, a first connecting plate and a second connecting plate are fixedly connected to the surface of the outer casing plate, and the first connecting plate and the second connecting plate are arranged opposite to each other. A first cold water outlet is fixedly connected to the upper end of the first connecting plate, and a first hot water inlet is fixedly connected to the lower end of the second connecting plate.

[0008] Furthermore, the first hot water inlet is connected to the first heat exchange vortex plate via the second connecting plate, and the other outlet of the first heat exchange vortex plate is connected to the first hot water outlet.

[0009] Furthermore, the first cold water outlet is connected to the second heat exchange vortex plate via the first connecting plate, and the other outlet of the second heat exchange vortex plate is connected to the first cold water inlet.

[0010] Furthermore, the outer cover plate is provided with disassembly components at both ends. The disassembly components include connecting flanges and cover plates. Connecting flanges are fixedly connected to both ends of the outer cover plate, and a cover plate is fixedly connected to one end of the connecting flanges.

[0011] Furthermore, the flow inlet / outlet component includes a second hot water outlet, a second hot water inlet, a second cold water inlet, and a second cold water outlet.

[0013] By adopting the above technical solution

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The cross arrangement of the first and second heat exchange vortex plates forms a spiral flow channel, reducing fluid stagnation areas and lowering the risk of fouling. The hollow structure of the vortex plates further optimizes fluid distribution, preventing impurity deposition caused by excessively slow local flow velocities;

[0016] 2. The cross-flow arrangement of the double-vortex plates expands the heat exchange area, while the hot and cold fluids flow in opposite directions, improving the heat transfer efficiency.

[0017] 3. The detachable components (connecting flanges and cover plates) at both ends of the outer casing allow for quick opening of the heat exchanger, facilitating cleaning of the internal volutes and inspection of the flow channels. Compared to traditional fixed structures, maintenance does not require complete disassembly, saving time and labor costs.

[0018] 4. The flow inlet and outlet components provide two interface configurations (such as the single-ended connection in Embodiment 1 and the double-ended connection in Embodiment 2), which can flexibly adapt to the cold and hot fluid circulation requirements of different scenarios and enhance the versatility of the equipment.

[0025] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1:

[0026] Please see Figures 1-3This utility model provides an embodiment of a novel heat exchanger for preventing dead-angle scaling, comprising an outer casing plate 2. A support bracket 5 is fixedly connected to the lower end of the outer casing plate 2. A heat exchange assembly is disposed inside the outer casing plate 2, and a flow inlet / outlet component is connected to the surface of the outer casing plate 2 through the heat exchange assembly. The heat exchange assembly includes a first heat exchange vortex plate 8 and a second heat exchange vortex plate 10. The first and second heat exchange vortex plates 8 and 10 are fixedly connected inside the outer casing plate 2, and are arranged intersectingly. Both the first and second heat exchange vortex plates 8 and 10 are hollow inside. The first and second heat exchange vortex plates 8 and 10 are precisely fixed inside the outer casing plate 2 according to design requirements. The accuracy of their intersecting positions is carefully checked, and suitable fasteners are used to ensure a secure installation that will not shift during subsequent operation. Simultaneously, the hollow channels inside the vortex plates are checked to ensure there are no obstructions, guaranteeing smooth fluid flow. The connection between the vortex plate and the outer casing plate 2 is sealed with sealant or other sealing materials to prevent fluid leakage.

[0027] In this embodiment, the flow inlet / outlet component includes a first hot water outlet 1, a first cold water outlet 3, a first connecting plate 4, a second connecting plate 6, and a first hot water inlet 7. One end of the outer casing 2 is fixedly connected to the first hot water outlet 1, and the other end is fixedly connected to the first cold water inlet 9. The surface of the outer casing 2 is fixedly connected to the first connecting plate 4 and the second connecting plate 6, which are arranged opposite to each other. The upper end of the first connecting plate 4 is fixedly connected to the first cold water outlet 3, and the lower end of the second connecting plate 6 is fixedly connected to the first hot water inlet 7. The first hot water inlet 7 is interconnected with the first heat exchange vortex plate 8 through the second connecting plate 6, and the other output of the first heat exchange vortex plate 8... The first hot water outlet 7 is connected to the first hot water outlet 1, and the first cold water outlet 3 is connected to the second heat exchange vortex plate 10 through the first connecting plate 4. The other outlet of the second heat exchange vortex plate 10 is connected to the first cold water inlet 9. The first hot water inlet 7 is connected to the second connecting plate 6 to ensure that hot water can flow smoothly into the first heat exchange vortex plate 8. At the same time, the other outlet of the first heat exchange vortex plate 8 is connected to the first hot water outlet 1 to realize the circulation path of hot water. In the same way, the first cold water outlet 3 is connected to the second heat exchange vortex plate 10 through the first connecting plate 4, and the other outlet of the second heat exchange vortex plate 10 is connected to the first cold water inlet 9 to complete the circulation connection of cold water.

[0028] By cross-arranging the first heat exchange vortex plate 8 and the second heat exchange vortex plate 10, and setting the first cold water outlet 3 opposite to the first hot water inlet 7, the area where the water remains still can be effectively reduced, ensuring that the internal water flow is always circulating, thereby preventing the accumulation of sediment in the dead corners of the exchange points inside the device.

[0029] Example 2:

[0030] Please see Figures 3-5 This utility model provides an embodiment of a novel heat exchanger for preventing dead-angle fouling, including an outer casing plate 2. A support bracket 5 is fixedly connected to the lower end of the outer casing plate 2. A heat exchange assembly is disposed inside the outer casing plate 2. A flow inlet / outlet assembly is connected to the surface of the outer casing plate 2 through the heat exchange assembly. The heat exchange assembly includes a first heat exchange vortex plate 8 and a second heat exchange vortex plate 10. The first heat exchange vortex plate 8 and the second heat exchange vortex plate 10 are fixedly connected inside the outer casing plate 2. The first heat exchange vortex plate 8 and the second heat exchange vortex plate 10 are arranged to cross each other, and the interior of the first heat exchange vortex plate 8 and the second heat exchange vortex plate 10 are both hollow. Similar to Embodiment 1, the first heat exchange vortex plate 8 and the second heat exchange vortex plate 10 are accurately fixed inside the outer casing plate 2 according to the design requirements, ensuring the positional accuracy of the cross arrangement, the secure installation, and the unobstructed internal hollow channels.

[0031] In this embodiment, the outer packaging plate 2 is provided with disassembly components at both ends. The disassembly components include connecting flanges 13 and cover plates 14. Connecting flanges 13 are fixedly connected to both ends of the outer packaging plate 2, and cover plates 14 are fixedly connected to one end of the connecting flanges 13. The cover plates 14 are fixed to both ends of the outer packaging plate 2 through the connecting flanges 13, thereby fixing the subsequent output and input ports.

[0032] In this embodiment, the flow inlet / outlet component includes a second hot water outlet 11, a second hot water inlet 12, a second cold water inlet 15, and a second cold water outlet 16. The second hot water inlet 12 and the second cold water outlet 16 are fixedly connected to the surface of the outer casing 2. The second hot water outlet 11 and the second cold water inlet 15 are fixedly connected to both ends of the outer casing 2 through cover plates 14. The second hot water inlet 12 and the second hot water outlet 11 are interconnected with the first heat exchange vortex plate 8, and the second cold water inlet 15 and the second cold water outlet 16 are interconnected with the second heat exchange vortex plate 10. (The last sentence appears to be incomplete and possibly refers to the installation of the first hot water outlet 11.) In addition to components such as outlet 1 and first cold water inlet 9, a second hot water inlet 12 and a second cold water outlet 16 are installed at appropriate positions on the surface of the outer casing plate 2. At both ends of the outer casing plate 2, first install connecting flanges 13 to ensure that the connecting flanges 13 are tightly connected to the outer casing plate 2. Fix the cover plate 14 to one end of the connecting flanges 13. Then ensure that the second hot water inlet 12 and the second hot water outlet 11 are interconnected with the first heat exchange vortex plate 8, and that the second cold water inlet 15 and the second cold water outlet 16 are interconnected with the second heat exchange vortex plate 10. Conduct a comprehensive inspection of all connection parts and ensure that there is no leakage through pressure testing and other methods.

[0033] By setting the second hot water inlet 12 and the second cold water outlet 16 on the same side, different working environments can be effectively adapted, thereby increasing the product's adaptability.

[0034] The cross arrangement of the first heat exchange vortex plate 8 and the second heat exchange vortex plate 10 forms a spiral flow channel, reducing fluid stagnation areas and lowering the risk of fouling. The hollow structure of the vortex plates further optimizes fluid distribution, preventing impurity deposition caused by excessively slow local flow velocities. The cross arrangement of the double vortex plates expands the heat exchange area, while the counter-current flow of hot and cold fluids improves heat transfer efficiency. The disassembly components (connecting flange 13 and cover plate 14) at both ends of the outer casing plate 2 allow for quick opening of the heat exchanger, facilitating cleaning of the internal vortex plates and inspection of the flow channels. Compared to traditional fixed structures, maintenance does not require complete disassembly, saving time and labor costs. The flow inlet and outlet components provide two interface configurations (such as the single-end connection in Embodiment 1 and the double-end connection in Embodiment 2), which can flexibly adapt to the hot and cold fluid circulation needs of different scenarios, enhancing the equipment's versatility.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
