Description

Technical Field

[0001] This utility model relates to the technical field of dry-wet combined cooling heat exchangers, specifically to a catalyst anti-fouling heat exchanger structure in a dry-wet combined cooling system. Background Technology

[0002] The structure of a combined wet and dry cooling tower mainly consists of several parts, including the outer shell, frame, finned air cooler, bare tube heat exchange coil, cooling packing, fan, water pump, and control system. The outer shell is made of metal, offering corrosion resistance and durability; the frame ensures the stability and structural support of the equipment; the finned air cooler increases the heat exchange area and improves heat exchange efficiency; the bare tube heat exchange coil is used in the wet cooling section to reduce the possibility of scaling; the cooling packing increases the contact area between water and air, achieving effective heat and mass transfer; the fan draws in outside air and cools it through the cooling packing; the water pump circulates the cooling water back to the cooling tower for reuse; and the control system enables automatic control and regulation of the entire system.

[0003] A search revealed existing technology (publication number: CN222481171U), which describes "a miniature dry-wet combined cooling tower, comprising a tower body, a water circulation mechanism disposed on one side of the tower body, and a fan mechanism installed at the top of the tower body. A water collection tank and a cooler are disposed within the tower body. The water collection tank is located at the bottom of the tower body. A first air inlet is disposed on the periphery of the tower body above the water collection tank. The cooler is installed within the tower body above the first air inlet. A microchannel heat exchanger is disposed within the tower body above the spray mechanism. The microchannel heat exchanger is disposed along the length direction of the spray mechanism, with one end extending out of the tower body along its length direction. The other end of the microchannel heat exchanger is connected to the cooler via a third connecting component, and the other end of the cooler extends out of the tower body. Second air inlets are disposed on both sides of the tower body along the width direction of the microchannel heat exchanger. Through the above technical solution, this utility model has the advantages of improving cooling effect and cooling efficiency, as well as reducing investment costs."

[0004] While existing dry-wet combined cooling towers achieve high cooling effects and temperature reduction efficiency, they still have some shortcomings: When air passes through the microchannel heat exchanger in existing dry-wet combined cooling towers, turbulence or impact turbulence may be formed due to the pores between the fins. This can easily generate sharp noise as the airflow blows through the pores between the fins, thus increasing the noise of the equipment operation. Secondly, the fins and flat tubes are in point contact, resulting in a small contact area and poor heat dissipation of the liquid inside the flat tube. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, a catalyst anti-fouling heat exchanger structure is provided in a dry-wet combined cooling system to solve the problems mentioned in the background.

[0006] To achieve the above objectives, a catalyst anti-fouling heat exchanger structure is provided in a combined dry and wet cooling system, comprising: a flat tube and a noise reduction component. One end of the flat tube is connected to an inlet manifold, and the other end of the flat tube is connected to an outlet manifold. Heat dissipation fins are connected between the flat tubes. A flow guide groove is provided inside the flat tube, and a single-layer perforated plate and a double-layer perforated plate are provided inside the flow guide groove. One end of the heat dissipation fin is connected to the single-layer perforated plate, and a double-layer perforated plate is connected between adjacent heat dissipation fins. The noise reduction component is connected to the upper and lower ends of the flat tube, and the noise reduction component includes an outer sound insulation plate and a sound-absorbing plate connected to the inner side of the sound insulation plate.

[0007] Furthermore, the flat tube has multiple parallel sets in the top view, and the multiple sets of flat tubes are connected into an integral structure by heat dissipation fins.

[0008] Furthermore, the heat dissipation fins are designed with a Y-shaped structure and are made of copper.

[0009] Furthermore, the single-layer perforated plate and the double-layer perforated plate have through holes in their internal structure, and the direction of the through holes is consistent with the flow direction inside the guide channel.

[0010] Furthermore, the outer wall of the water inlet manifold is provided with a first water inlet hole, and the side of the water inlet manifold connected to the flat pipe is provided with a first water outlet hole.

[0011] Furthermore, a second water inlet is provided on the side where the water outlet manifold connects to the flat pipe, and a second water outlet is provided at the axial end of the water outlet manifold.

[0012] Furthermore, the noise reduction component includes a tubular structure and a square bucket structure, with the tubular structure connected to the outer end of the square bucket structure.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By connecting the flat tube, the inlet manifold, and the outlet manifold, the high-temperature liquid is dissipated through the heat dissipation fins connected to the flat tube. Since the single-layer orifice plate and the multi-layer orifice plate are in direct contact with the high-temperature liquid in the guide groove, the contact conduction area is increased, thereby enabling the single-layer orifice plate and the multi-layer orifice plate to quickly and effectively transfer the heat of the high-temperature liquid to the heat dissipation fins on the outside. Then, the heat exchange effect is achieved by the airflow flowing through the flat tube in the vertical direction, which greatly improves the heat dissipation effect of the flat tube.

[0015] 2. By utilizing the sound insulation and sound absorption panels included in the noise reduction components, and by connecting the noise reduction components to the flat tubes and manifolds, the noise generated when air flows through the heat dissipation fins between the flat tubes is absorbed and isolated by the sound absorption and sound insulation panels on the outside, which greatly reduces the noise generated when the heat exchanger is working.

[0021] Reference Figures 1 to 4 As shown, this utility model provides a catalyst anti-fouling heat exchanger structure in a combined dry and wet cooling system, including: a flat tube 1 and a noise reduction component 4. One end of the flat tube 1 is connected to an inlet water manifold 2, and the other end of the flat tube 1 is connected to an outlet water manifold 3. Heat dissipation fins 11 are connected between the flat tubes 1. A flow guide groove 12 is provided inside the flat tube 1, and a single-layer perforated plate 13 and a double-layer perforated plate 14 are provided inside the flow guide groove 12. One end of the heat dissipation fin 11 is connected to the single-layer perforated plate 13, and a double-layer perforated plate 14 is connected between adjacent heat dissipation fins 11. The noise reduction component 4 is connected to the upper and lower ends of the flat tube 1, and the noise reduction component 4 includes an outer sound insulation plate 41 and a sound absorption plate 42 connected to the inner side of the sound insulation plate 41.

[0022] In this embodiment, the flat tube 1, the inlet water manifold 2, the outlet water manifold 3, and the noise reduction component 4 constitute the main structure of the catalyst anti-fouling heat exchanger in the dry-wet combined cooling system involved in this application.

[0023] The heat exchanger involved in this application uses a catalyst, which, by being added to the liquid in the cooling system, can prevent the formation of scale inside the heat exchanger.

[0024] Specifically, the sound insulation panel 41 is made of double-layer metal material, and a foam board is installed inside the double-layer metal layer, while the sound absorption panel 42 is made of polyester fiber material.

[0025] It should be noted that by connecting the noise reduction component 4 of the sound insulation plate 41 to the outer wall of the flat tube 1, the inlet water collection pipe 2, and the outlet water collection pipe 3, a closed connection structure is formed around the flat tube 1, so that the airflow on the outside can be guided through the flat tube 1 and the heat dissipation fins 11 on the inside.

[0026] like Figure 2 , Figure 3 and Figure 4 In the above view, the flat tube 1 has multiple parallel sets, and the multiple sets of flat tubes 1 are connected into an integral structure by heat dissipation fins 11. The heat dissipation fins 11 are Y-shaped and made of copper. The single-layer perforated plate 13 and the double-layer perforated plate 14 have through holes in their internal structure, and the direction of the through holes is consistent with the flow direction inside the guide channel 12. The outer wall of the water inlet manifold 2 has a first water inlet hole 21, and the side of the water inlet manifold 2 connected to the flat tube 1 has a first water outlet hole 22. The side of the water outlet manifold 3 connected to the flat tube 1 has a second water inlet hole 31, and the axial end of the water outlet manifold 3 has a second water outlet hole 32. The noise reduction component 4 includes a tubular structure and a square bucket structure, and the tubular structure is connected to the outer end of the square bucket structure.

[0027] Specifically, the single-layer orifice plate 13 and the multi-layer orifice plate 14 are made of metal thermally conductive material, and the internal through holes facilitate the free flow of heat exchange liquid in the flat tube 1.

[0028] Specifically, the second water outlet 32 ​​can be opened at either end of the water outlet manifold 3, or it can be opened at both ends simultaneously, and then the two ends are connected to the cooling system pipes through a pipeline.

[0029] In operation, the flat tubes, inlet manifold, and outlet manifold are interconnected, allowing the high-temperature liquid to dissipate heat through the heat dissipation fins connected to the flat tubes. Since the single-layer and multi-layer perforated plates are in direct contact with the high-temperature liquid in the guide channel, the contact conduction area is increased, enabling the single-layer and multi-layer perforated plates to quickly and effectively transfer the heat of the high-temperature liquid to the outer heat dissipation fins. Then, the airflow flowing vertically through the flat tubes achieves heat exchange, significantly improving the heat dissipation effect of the flat tubes. The noise reduction components, including sound insulation and sound absorption panels, are connected to the flat tubes and manifolds. When air flows through the heat dissipation fins between the flat tubes, the noise generated is absorbed and isolated by the outer sound absorption and sound insulation panels, greatly reducing the noise generated during heat exchanger operation.

[0030] The catalyst anti-fouling heat exchanger structure in the dry-wet combined cooling system of this utility model can effectively solve the problems mentioned in the background technology. It achieves sound insulation and noise reduction effects on the basis of the existing catalyst anti-fouling heat exchanger structure technology in the dry-wet combined cooling system, while also enhancing the heat exchange effect of the heat exchanger.
