Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for power equipment, and specifically to a heat dissipation structure for power equipment. Background Technology

[0002] During operation, power equipment (such as energy storage power stations, transformer cabinets, etc.) generates a lot of heat through its internal electronic components (such as transformers, power modules, controllers, etc.). If the heat cannot be dissipated in a timely and effective manner, the internal temperature of the equipment will rise sharply, which will lead to the degradation of component performance, shortened lifespan, and may even cause equipment failure.

[0003] Currently, power equipment generally adopts air cooling, which uses a fan to force the external ambient air into the equipment and remove the heat generated by the components. This method is simple in structure, low in cost, and widely used.

[0004] However, in actual operation, traditional air-cooled heat dissipation structures have some obvious technical defects: First, the outside air usually contains a large amount of dust, lint and other impurities. These impurities enter the equipment with the airflow and adhere to the surface of components and heat sinks, forming a heat insulation layer that seriously hinders heat dissipation. To solve the dust problem, some equipment will install filters at the air inlet. However, after absorbing a large amount of dust, the mesh of ordinary filters is easily blocked, resulting in increased airflow resistance and a sharp reduction in air volume, and the heat dissipation effect is reduced instead of increased. Second, in summer or high-temperature environments, the ambient air temperature is already high. After being drawn into the equipment, its cooling capacity is greatly reduced, making it difficult to effectively cool high-heat components. This requires a device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat dissipation structure for power equipment, solving the problems of impurities in the air easily affecting heat dissipation and insufficient heat dissipation efficiency in high-temperature summers.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat dissipation structure for power equipment, including a mounting base for fixing to the power equipment, a hinged rotating mounting frame connected to one side of the mounting base, a filter screen detachably connected to the side of the mounting frame near the mounting base, and a fixing mechanism for fixing the filter screen on one side of the filter screen. The front of the mounting base is provided with a cleaning chamber, and the surface of the cleaning chamber is provided with an air inlet to draw outside air into the interior. The interior of the cleaning chamber is provided with a cleaning mechanism to clean the filter screen. The interior of the mounting base can also be detachably connected with a heat exchange plate, and the top of the heat exchange plate is provided with a water inlet pipe and a water return pipe.

[0007] Optionally, a mounting shaft is fixedly connected to the side of the mounting bracket near the mounting base, and a mounting seat is rotatably connected to the outer surface of the mounting shaft. An insert plate is fixedly connected to one side of the filter screen, and the insert plate is inserted into the mounting seat to position the filter screen.

[0008] Optionally, the fixing mechanism includes a positioning groove and a positioning buckle. The positioning groove is formed on the side of the mounting bracket away from the mounting axis, and the positioning buckle is fixedly connected to the side of the filter screen away from the insert plate. The positioning buckle is U-shaped and is detachably connected to the positioning groove to fix the filter screen.

[0009] Optionally, the cleaning mechanism includes a guide plate and a cleaning brush. The guide plate is slidably connected to the surface of the cleaning chamber, and the cleaning brush is fixedly connected to the side of the guide plate near the filter screen. One side of the cleaning brush is in contact with one side of the filter screen to clean the filter screen.

The threaded rod extends into the interior of the cleaning chamber, and one side of the guide plate is threadedly connected to the threaded rod, so that the drive motor drives the threaded rod to rotate and move the guide plate up and down.

[0011] Optionally, a guide groove in the vertical direction is provided on one side of the cleaning chamber, and the end of the guide plate away from the threaded rod is slidably connected to the guide groove.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1 to 5This utility model provides a technical solution: a heat dissipation structure for power equipment, including a mounting base 1, which is used to fix the power equipment. A reversible mounting frame 2 is hinged to one side of the mounting base 1. A filter screen 3 is detachably connected to the side of the mounting frame 2 near the mounting base 1. A fixing mechanism is provided on one side of the filter screen 3 to fix the filter screen 3.

[0019] The front of the mounting base 1 is provided with a cleaning chamber 4. The surface of the cleaning chamber 4 is provided with an air inlet 5 to draw outside air into the interior. The interior of the cleaning chamber 4 is provided with a cleaning mechanism to clean the filter screen 3. The interior of the mounting base 1 is also detachably connected with a heat exchange plate 6. The top of the heat exchange plate 6 is provided with a water inlet pipe 7 and a water return pipe 8.

[0020] Power equipment such as transformer cabinets, charging cabinets, and energy storage stations often have air intake structures on their side walls. This device is installed at the air intake end after disassembling the original air intake structure, providing airflow and cooling to the power equipment. The mounting base 1 has ear plates on both sides of its back. The mounting base is suspended from the side wall of the power equipment using the ear plates and bolts. A sealing gasket is located on the back of the mounting base 1. After the mounting base 1 is fixed in place with bolts, the sealing gasket seals any gaps to reduce air leakage. The mounting bracket 2 can be opened by reversing it from one side of the mounting base 1, allowing for easy replacement of the filter screen 3 if it is damaged. The fixing mechanism allows for quick replacement of the filter. The installation and disassembly of the net 3 reduces the difficulty of subsequent maintenance. A fan is installed in the air inlet 5, and the fan is a forward and reverse fan (the forward and reverse fan with the publication number CN208294801U utility model patent can be used, or the forward and reverse fan of the product agent company with model number PD25030B12HH can be used). It can perform air intake and air blowing operations. The fan draws in the outside air, so that the outside air passes through the cleaning chamber 4 and enters the inside of the power equipment to dissipate heat from the internal components of the power equipment. In summer, cold water can also be introduced into the water inlet pipe 7 to cool the heat exchange plate 6 through the water inlet pipe 7, so that the air can be cooled when passing through the heat exchange plate 6, thereby improving the heat dissipation efficiency of the internal components.

[0021] In this embodiment, as a preferred option, a mounting shaft 9 is fixedly connected to the side of the mounting bracket 2 near the mounting base 1, and a mounting seat 10 is rotatably connected to the outer surface of the mounting shaft 9. An insert plate 11 is fixedly connected to one side of the filter screen 3. The insert plate 11 is inserted into the mounting seat 10 to position the filter screen 3. The fixing mechanism includes a positioning groove 12 and a positioning buckle 13. The positioning groove 12 is opened on the side of the surface of the mounting bracket 2 away from the mounting shaft 9. The positioning buckle 13 is fixedly connected to the side of the filter screen 3 away from the insert plate 11. The positioning buckle 13 is U-shaped and is detachably connected to the positioning groove 12 to fix the filter screen 3.

[0022] After one end of the filter screen 3 is inserted into the mounting base 10, rotating the filter screen 3 will cause the mounting base 10 to rotate around the mounting shaft 9. After rotation, the positioning buckle 13 on one side of the filter screen 3 can be inserted into the positioning groove 12. Through the fixed cooperation between the positioning buckle 13 and the positioning groove 12, and the insertion plate 11 and the mounting base 10, the position of the filter screen 3 can be fixed. The positioning buckle 13 is U-shaped. When it is necessary to disassemble, press the positioning buckle 13 to separate the positioning buckle 13 from the positioning groove 12. Then rotate the filter screen 3 and pull it out from the mounting base 10 to remove the filter screen 3 from the mounting bracket 2 for quick installation and replacement of the filter screen 3.

[0023] In this embodiment, as a preferred solution, the cleaning mechanism includes a guide plate 14 and a cleaning brush 15. The guide plate 14 is slidably connected to the surface of the cleaning chamber 4, and the cleaning brush 15 is fixedly connected to the side of the guide plate 14 near the filter screen 3. One side of the cleaning brush 15 is in contact with one side of the filter screen 3 to clean the filter screen 3. A drive motor 16 is fixedly connected to the bottom of the mounting base 1, and a threaded rod 17 is fixedly connected to the output end of the drive motor 16. The threaded rod 17 penetrates into the interior of the cleaning chamber 4, and one side of the guide plate 14 is threadedly connected to the threaded rod 17 so that the drive motor 16 drives the threaded rod 17 to rotate and move the guide plate 14 up and down.

[0024] The drive motor 16 can rotate the threaded rod 17 at the output end. The threaded rod 17 is threadedly connected to one end of the guide plate 14. During the rotation of the threaded rod 17, it will drive the guide plate 14 to move up or down. The movement of the guide plate 14 can drive the cleaning brush 15 to move up and down. During the up and down movement, the cleaning brush 15 will contact the filter screen 3, thereby brushing off the dirt on the surface of the filter screen 3, reducing the possibility of external dust clogging the filter screen 3, and improving the air intake efficiency of the filter screen 3. The cleaning brush 15 can be fixed to the guide plate 14 with bolts. The cleaning brush can be replaced by unscrewing the bolts to maintain a high cleaning efficiency. During the process of the drive motor 16 driving the cleaning plate to clean the filter screen 3, the fan in the air inlet 5 reverses to blow the dust outward to prevent dust from being drawn into the equipment during the cleaning process. The forward and reverse rotation of the fan and the electrical connection of the fan are well known technologies to those skilled in the art and will not be described in detail here.

[0025] In this embodiment, as a preferred option, a guide groove 18 is provided on one side of the cleaning chamber 4 in a vertical direction. The end of the guide plate 14 away from the threaded rod 17 is slidably connected to the guide groove 18. The end of the guide plate 14 located inside the guide groove 18 is rotatably connected to a guide wheel 19, and the guide wheel 19 is slidably connected to the inner wall of the guide groove 18.

[0026] During the process of the drive motor 16 driving the guide plate 14 to move, the other end of the guide plate 14 will slide up and down in the guide groove 18, which improves the contact stability between the cleaning plate on one side of the guide plate 14 and the filter screen 3, making the cleaning efficiency higher. Through the guide wheel 19 set on the guide plate 14, the guide wheel 19 can reduce the sliding friction between the guide plate 14 and the guide groove 18, making the guide plate 14 move more smoothly and reducing vibration.

[0027] In this embodiment, as a preferred option, a plurality of heat exchange fins 20 are fixedly connected to the middle of the heat exchange plate 6, and a U-shaped water supply pipe 21 is connected through the middle of the heat exchange fins 20. The two ends of the water supply pipe 21 are connected to the inlet pipe 7 and the return pipe 8, respectively.

[0028] The water supply pipe 21 is arranged in a U-shape inside the heat exchange plate 6. There are multiple heat exchange fins 20. The heat exchange fins 20 are in contact with the water supply pipe 21. When cold water is introduced into the water supply pipe 21 through the inlet pipe 7, the cold water will cool down the heat exchange fins 20. As the air passes through the heat exchange fins 20, the air will be cooled down after contacting the heat exchange fins 20. In summer, this reduces the temperature of the air entering the equipment and improves the heat dissipation efficiency. The water that has passed through the heat exchange fins 20 will be discharged from the other end of the water supply pipe 21 and then enter the return water pipe 8. The water in the return water pipe 8 can be circulated back into the inlet pipe 7 after being cooled down.

[0029] In this invention, the working steps of the device are as follows: 1. Remove the original air inlet structure and fix this device to the air inlet end of the equipment, securing it firmly with bolts; 2. Connect the water supply pipe and return pipe 8 to the external pipeline so that cold water can flow into the heat exchange plate 6 to cool the heat exchange fins 20. Start the fan in the air inlet 5 to draw outside air into the equipment to cool the equipment. 3. When cleaning is required after a period of use, the drive motor 16 drives the threaded rod 17 to rotate, so that the cleaning plate cleans the filter screen 3. At the same time, the fan reverses to blow out the cleaned dust. After cleaning, the drive motor 16 stops and the guide plate 14 is positioned between the air inlets 5 to prevent the air inlets 5 from being blocked, which would reduce the air intake efficiency. Then the fan rotates forward to continue to dissipate heat and cool down the internal equipment. 4. After the filter screen 3 is damaged, open the mounting bracket 2, pinch the positioning buckle 13 to separate the positioning buckle 13 from the positioning groove 12, then rotate the filter screen 3, and then pull the insert plate 11 out of the mounting base 10 to remove the filter screen 3. Then install the new filter screen 3 back according to the same steps. 5. After prolonged use, the mounting bracket 2 can be opened to clean the dust remaining in the mounting bracket 2 and mounting base 1.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model.
