Description

Technical Field

[0001] This application relates to the technical field of air conditioning, and in particular to a cooling coil for a computer room air conditioner. Background Technology

[0002] With the rapid development of data centers and communication base stations, the cooling efficiency and energy consumption of data center air conditioners, as key equipment, are becoming increasingly prominent issues. The surface cooler, as a core component of data center air conditioners, directly affects the cooling effect and energy consumption of the entire system.

[0003] In existing technologies, the surface cooler is the core heat exchange component. Due to the circulation of indoor and outdoor air, a large amount of air carrying pollutants such as dust, lint, and smoke particles continuously passes over the surface cooler. These pollutants of varying particle sizes will gradually settle and adsorb onto the heat exchange fins on the surface of the surface cooler. This layer of pollutant accumulation will become thicker and thicker, which will not only seriously hinder the heat exchange efficiency between the air and the fins, but also increase wind resistance, resulting in a significant increase in the energy consumption of the air conditioning system, a significant reduction in the cooling and heating effect, and may even cause equipment failure due to long-term dust accumulation, thus shortening the service life of the surface cooler. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a surface cooler for computer room air conditioning, which overcomes the deficiencies of existing technologies. It aims to solve the problem that, as a core heat exchange component, the surface cooler is constantly exposed to air carrying pollutants such as dust, lint, and smoke particles due to indoor and outdoor air circulation. These pollutants of varying particle sizes gradually settle and adhere to the heat exchange fins on the surface of the surface cooler. This layer of pollutant buildup becomes increasingly thick, severely hindering the heat exchange efficiency between the air and the fins, increasing wind resistance, leading to a significant increase in air conditioning system energy consumption, a substantial reduction in cooling and heating performance, and even potential equipment failure due to long-term dust accumulation, thus shortening the lifespan of the surface cooler.

[0005] To achieve the above objectives, this application provides the following technical solution: a computer room air conditioner surface cooler, including a surface cooler box, a frame connected to the inner bottom surface of the surface cooler box, a plurality of heat exchange fins arranged inside the frame, the plurality of heat exchange fins being spaced apart, mounting frames provided on both sides of the frame, a lead screw provided inside the mounting frame on the right side, a moving block threaded to the outer wall of the lead screw, an installation rod connected to one side of the moving block, and a plurality of wiping blocks connected to one side of the installation rod, the wiping blocks being disposed between two heat exchange fins.

[0006] By adopting the above technical solution, the spaced heat exchange fins form air channels, allowing air to exchange heat with them as it flows through. When the lead screw rotates, the threaded moving block moves along the screw's axial direction, thereby moving the mounting rod and wiping block between the heat exchange fins. This allows for wiping the fins. The spaced arrangement of the fins increases the contact area and turbulence between the air and the fins, improving heat exchange efficiency. The wiping block periodically wipes the fins, preventing dust accumulation and ensuring optimal heat exchange performance.

[0007] As a preferred technical solution of this application, a drive motor is provided inside the mounting frame on the right side, and the output end of the drive motor is connected to the lead screw.

[0008] By adopting the above technical solution, after the drive motor starts, its output shaft drives the lead screw to rotate, providing power for the movement of the moving block, so that the wiping block can automatically move between the heat exchange fins to perform wiping work, realizing the automation of the wiping process, eliminating the need for manual operation, improving cleaning efficiency, and also facilitating regular automatic cleaning to better ensure the cleanliness of the heat exchange fins.

[0009] As a preferred technical solution of this application, a guide rod is provided inside the mounting frame on the left side, and a moving block is slidably provided on the outer wall of the guide rod, with one side of the moving block connected to one side of the mounting rod.

[0010] By adopting the above technical solution, the moving block slides on the guide rod, which provides a stable moving guide for the moving block, so that it can move more smoothly under the drive of the screw. This ensures that the wiping block moves along a straight line between the heat exchange fins, improves the stability and accuracy of the moving block's movement, and thus ensures the uniformity and reliability of the wiping block's wiping of the heat exchange fins, avoiding the wiping block from shaking or deviating and affecting the wiping effect.

[0011] As a preferred technical solution of this application, the inner bottom surface of the surface cooling box is provided with an installation groove, and a collection box is provided inside the installation groove.

[0012] By adopting the above technical solution, the collection box is used to collect dust wiped off the heat exchange fins and impurities such as condensate that may be generated. The mounting slot provides a fixed installation position for the collection box, which facilitates the centralized collection and treatment of impurities, keeps the inside of the surface cooler clean, prevents the accumulation of impurities from affecting the normal operation of the surface cooler, and also facilitates the regular cleaning of the collection box.

[0013] As a preferred technical solution of this application, a collection plate is connected to one side of the frame, the collection plate is inclined, and one side of the collection plate is connected to the collection box.

[0014] By adopting the above technical solution, the inclined collection plate can guide dust and condensate falling from the heat exchange fins into the collection box. The impurities are then slid down the collection plate into the collection box by gravity, which improves the efficiency of impurity collection, ensures that impurities can enter the collection box smoothly, reduces the possibility of impurities scattering around in the surface cooling box, and further ensures the cleanliness of the inside of the surface cooling box.

[0015] As a preferred technical solution of this application, the heat exchange fins are provided with a plurality of heat exchange tubes inside, and the plurality of heat exchange tubes are evenly distributed.

[0016] By adopting the above technical solution, refrigerant flows inside the heat exchange tubes. When air flows through the heat exchange fins, heat is transferred to the refrigerant inside the heat exchange tubes, thus cooling the air. The uniformly distributed heat exchange tubes ensure more even heat transfer and higher efficiency, preventing localized overheating or overcooling. This improves the overall performance of the surface cooler and its cooling effect on the air, ensuring the stability of the computer room air conditioner's temperature regulation.

[0017] As a preferred technical solution of this application, both sides of the frame are connected to fixing plates, and the bottom surface of the surface cooling box is provided with fixing holes. Fixing bolts are provided inside the fixing holes, and one end of the fixing bolt passes through the fixing plate and is threaded into the fixing hole.

[0018] By adopting the above technical solution, the fixing plate is connected and fixed to the bottom surface of the surface cooler box with fixing bolts, thereby stably installing the frame inside the surface cooler box. This ensures that the frame and internal heat exchange fins and other components will not shake or shift during operation, improving the stability and reliability of the frame installation, ensuring the stability of the surface cooler structure, and facilitating long-term stable heat exchange.

[0019] As a preferred technical solution of this application, a grid plate is provided on one side of the surface cooling box.

[0020] By adopting the above technical solution, the grille is used for ventilation, allowing air to smoothly enter the surface cooler box and exchange heat with the heat exchange fins. At the same time, it also plays a certain role in filtration, preventing large particles of impurities from entering the surface cooler box, ensuring smooth airflow, and providing the necessary conditions for the heat exchange process of the surface cooler. Meanwhile, its filtration function can reduce the entry of dust and other impurities into the surface cooler box, protecting the internal heat exchange fins and other components, and extending the service life of the surface cooler.

[0021] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] 1. Start the drive motor, and its output end drives the lead screw to automatically clean the heat exchange fins with the wiping block, preventing dust accumulation from affecting heat exchange efficiency. Combined with the collection plate and collection box, impurities are collected in a centralized manner, reducing manual maintenance costs and maintaining the high-efficiency operation of the surface cooler for a long time.

[0023] 2. The frame is fixed inside the surface cooling box by fixing plates and fixing bolts. The guide rod and lead screw work together to ensure that the wiping mechanism moves smoothly, avoid damage caused by component shaking, and extend the service life of the equipment.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1 - Figure 4As shown in the figure, this embodiment provides a surface cooler for a computer room air conditioner, including a surface cooler box 1. A frame 2 is connected to the bottom surface of the surface cooler box 1. Several heat exchange fins 3 are arranged inside the frame 2, spaced apart. Mounting frames 4 are provided on both sides of the frame 2. A lead screw 5 is installed inside the mounting frame 4 on the right side. A moving block 6 is threaded to the outer wall of the lead screw 5. An installation rod 7 is connected to one side of the moving block 6, and several wiping blocks 8 are connected to one side of the installation rod 7. The wiping blocks 8 are positioned between two heat exchange fins 3. The spaced-apart heat exchange fins 3 form an air channel, allowing heat exchange with the heat exchange fins 3 when air flows through. When the lead screw 5 rotates, the threaded moving block 6 moves axially along the lead screw 5, thereby moving the installation rod 7 and the wiping blocks 8 between the heat exchange fins 3, wiping the heat exchange fins 3. The spaced-apart heat exchange fins 3 increase the contact area and turbulence between the air and the heat exchange fins 3, improving heat exchange efficiency. The wiping block 8 can be used to wipe the heat exchange fins 3 regularly to prevent the accumulation of dust and other contaminants and ensure the heat exchange effect.

[0031] In this embodiment, as Figure 2 and Figure 3 As shown, the mounting frame 4 on the right is equipped with a drive motor 9. The output end of the drive motor 9 is connected to the lead screw 5. After the drive motor 9 is started, its output shaft drives the lead screw 5 to rotate, providing power for the movement of the moving block 6. This enables the wiping block 8 to move automatically between the heat exchange fins 3 to perform wiping work, thus automating the wiping process without manual operation, improving cleaning efficiency, and facilitating regular automatic cleaning to better ensure the cleanliness of the heat exchange fins 3.

[0032] In this embodiment, as Figure 2 As shown, a guide rod 10 is provided inside the mounting frame 4 on the left side. A moving block 6 is slidably provided on the outer wall of the guide rod 10. One side of the moving block 6 is connected to one side of the mounting rod 7. The moving block 6 slides on the guide rod 10, providing a stable guide for the moving block 6, so that it can move more smoothly under the drive of the lead screw 5. This ensures that the wiping block 8 moves along a straight line between the heat exchange fins 3, improving the stability and accuracy of the movement of the moving block 6. This, in turn, ensures the uniformity and reliability of the wiping block 8 in wiping the heat exchange fins 3, and avoids the wiping block 8 from shaking or deviating, which would affect the wiping effect.

[0033] In this embodiment, as Figure 2 and Figure 4As shown, an installation groove 11 is provided on the bottom surface of the surface cooler box 1. A collection box 12 is installed inside the installation groove 11. The collection box 12 is used to collect dust wiped off the heat exchange fins 3 and impurities such as condensate that may be generated. The installation groove 11 provides a fixed installation position for the collection box 12, which facilitates the centralized collection and treatment of impurities, keeps the inside of the surface cooler box 1 clean, prevents the accumulation of impurities from affecting the normal operation of the surface cooler, and also facilitates the regular cleaning of the collection box 12.

[0034] In this embodiment, as Figure 2 and Figure 4 As shown, a collection plate 13 is connected to one side of the frame 2. The collection plate 13 is inclined and one side of the collection plate 13 is connected to the collection box 12. The inclined collection plate 13 can guide dust and condensate falling from the heat exchange fins 3 into the collection box 12. The impurities are made to slide down the collection plate 13 into the collection box 12 by gravity, which improves the efficiency of impurity collection, ensures that impurities can enter the collection box 12 smoothly, reduces the possibility of impurities scattering around in the surface cooling box 1, and further ensures the cleanliness of the inside of the surface cooling box 1.

[0035] In this embodiment, as Figure 2 and Figure 4 As shown, the heat exchange fins 3 have several heat exchange tubes 14 evenly distributed inside. Refrigerant flows through the heat exchange tubes 14. When air flows through the heat exchange fins 3, heat is transferred to the refrigerant in the heat exchange tubes 14, thus cooling the air. The evenly distributed heat exchange tubes 14 ensure more uniform heat transfer and higher efficiency, preventing localized overheating or overcooling. This improves the overall performance of the surface cooler and its cooling effect on the air, ensuring the stability of the computer room air conditioner's temperature regulation.

[0036] In this embodiment, as Figure 2 and Figure 4 As shown, both sides of the frame 2 are connected to fixing plates 15. The bottom surface of the surface cooler box 1 is provided with fixing holes 16. Fixing bolts 17 are installed inside the fixing holes 16. One end of the fixing bolt 17 passes through the fixing plate 15 and is threaded into the fixing hole 16. The fixing plate 15 is connected and fixed to the bottom surface of the surface cooler box 1 by fixing bolts 17, thereby stably installing the frame 2 inside the surface cooler box 1. This ensures that the frame 2 and the internal heat exchange fins 3 and other components will not shake or shift during operation, improving the stability and reliability of the frame 2 installation, ensuring the stability of the surface cooler structure, and facilitating long-term stable heat exchange.

[0037] In this embodiment, as Figure 1As shown, a grille plate 18 is provided on one side of the surface cooler box 1. The grille plate 18 is used for ventilation, allowing air to smoothly enter the surface cooler box 1 and exchange heat with the heat exchange fins 3. At the same time, it also plays a certain role in filtration, preventing large particles of impurities from entering the surface cooler box 1, ensuring smooth air circulation, and providing the necessary conditions for the heat exchange process of the surface cooler. At the same time, its filtration function can reduce the entry of dust and other impurities into the surface cooler box 1, protect the internal heat exchange fins 3 and other components, and extend the service life of the surface cooler.

[0038] Working Principle: The drive motor 9 is started, and its output drives the lead screw 5 to rotate. The rotation of the lead screw 5 moves the moving block 6, which in turn moves the mounting rod 7. The mounting rod 7 then moves the wiping block 8. The wiping block 8 is positioned between two heat exchange fins 3, allowing it to wipe the fins and prevent dust accumulation, thus ensuring efficient heat exchange. The guide rod 10 within the left mounting frame 4 provides stable guidance for the moving block 6, enabling it to move more smoothly under the drive of the lead screw 5. This ensures the wiping block 8 moves along a straight line between the heat exchange fins 3, improving the uniformity and reliability of the wiping process. Refrigerant flows through the heat exchange tubes 14, and the spaced-apart heat exchange fins 3 form air channels. When air flows through, it comes into full contact with the heat exchange fins 3, transferring heat to the refrigerant within the heat exchange tubes 14, thereby cooling the air. The evenly distributed heat exchange tubes 14 ensure more uniform heat transfer, improving heat exchange efficiency and air cooling effect, thus extending the lifespan of the surface cooler.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
