Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a multi-channel heat dissipation structure for power distribution cabinet. Background Technology

[0002] As a crucial piece of equipment in a power system, the main function of a distribution cabinet is to centrally control, distribute, and protect electrical energy. Inside the distribution cabinet, electrical components generate a significant amount of heat during operation. If this heat cannot be dissipated effectively and promptly, it can affect the normal operation of the equipment, potentially leading to malfunctions or damage. Therefore, a well-designed heat dissipation structure is essential to ensure that the internal temperature of the distribution cabinet remains within a safe range, thereby extending the equipment's lifespan.

[0003] Existing power distribution cabinets typically employ natural convection or forced air cooling to dissipate heat. Common designs include adding cooling fans, installing ventilation holes, or using thermally conductive materials. For example, some power distribution cabinets use ventilation holes and air ducts on the cabinet body to allow outside air to flow into the cabinet, while fans accelerate the expulsion of hot air to lower the internal temperature. Although these existing cooling structures can reduce the internal temperature of the power distribution cabinet to some extent, their designs, which often involve a single-height heat dissipation outlet, fail to adequately consider the temperature distribution in different areas within the cabinet, thus affecting overall heat dissipation efficiency. Therefore, a multi-channel heat dissipation structure for power distribution cabinets is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-channel heat dissipation structure for a power distribution cabinet, aiming to improve the problem that the single-height heat dissipation outlet in the prior art fails to fully consider the temperature distribution in different areas inside the power distribution cabinet, thus affecting the overall heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-channel heat dissipation structure for a power distribution cabinet includes a cabinet body, a heat dissipation mechanism inside the cabinet body, a positioning mechanism on the top of the cabinet body, and a waterproof platform fixedly connected to the bottom of the cabinet body.

[0007] The heat dissipation mechanism includes a cooling fan, a blower box, and an air outlet frame. The cooling fan is installed inside the cabinet and has a filter plate on its top. The blower box is fixedly connected to the top wall of the cabinet's inner cavity, and the air outlet frame is fixedly connected to the inner wall of the cabinet. One air outlet frame is fixedly connected to the middle of the cabinet's inner cavity, and the other air outlet frame is fixedly connected to the bottom of the cabinet's inner cavity. A diverter plate is fixedly connected between the blower box and the air outlet frame. The blower box, diverter plate, and waterproof platform are connected to form an air duct. An air blowing slot is opened inside the air outlet frame.

[0008] As a further description of the above technical solution:

[0009] The cabinet has a through groove inside, a dustproof mesh is embedded inside the groove, and louvers are provided on the outside of the dustproof mesh.

[0010] As a further description of the above technical solution:

[0011] The positioning mechanism includes a slide plate, which is fixedly connected to the top of the cabinet. The side wall of the filter plate is slidably connected between the slide plates. A sleeve is fixedly connected inside the slide plate. A locking block is provided inside the sleeve. A recessed hole is opened inside the filter plate. The locking block is slidably connected inside the recessed hole.

[0012] As a further description of the above technical solution:

[0013] The sleeve has a slider that is slidably connected inside, and the locking block is fixedly connected to the side wall of the slider. The locking block is slidably connected inside the sleeve through the slider.

[0014] As a further description of the above technical solution:

[0015] A spring is installed inside the sleeve. One end of the spring is fixedly connected to the side wall of the slider, and the other end of the spring is fixedly connected to the inside of the sleeve.

[0016] As a further description of the above technical solution:

[0017] The filter plate covers the top of the cooling fan, and the air box cover is located at the bottom of the cooling fan.

[0018] As a further description of the above technical solution:

[0019] A positioning ring is fixedly connected to the top of the cabinet, and a top frame is provided on the top of the cabinet. The side wall of the top frame is slidably connected inside the positioning ring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting air outlet frames of different heights inside, uniform heat dissipation of different areas inside the cabinet is effectively achieved. The air outlet frames of different heights can be arranged in a targeted manner according to the temperature distribution inside the distribution cabinet. Since hot air will rise naturally, the air outlet frames at higher positions can effectively exhaust the hot air at the top of the cabinet, while the air outlet frames at lower positions can guide the air flow at the bottom, increase the speed and efficiency of air flow, thereby accelerating the overall heat dissipation process.

[0022] 2. In this utility model, the filter plate can be easily pulled out or installed by pulling the handle, without the need for complicated tools or cumbersome steps. This method not only saves maintenance time but also ensures regular cleaning of the filter plate, guaranteeing the effectiveness of air filtration and further improving the heat dissipation effect of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2This utility model provides an embodiment of a multi-channel heat dissipation structure for a power distribution cabinet, comprising a cabinet body 1. The cabinet body 1 has an internal heat dissipation mechanism that effectively reduces the internal temperature, ensuring stable and safe operation of the equipment. A positioning mechanism is located at the top of the cabinet body 1, and a waterproof platform 5 is fixedly connected to the bottom of the cabinet body 1 to elevate it. The heat dissipation mechanism includes a cooling fan 2, a fan box 3, and an air outlet frame 6. The cooling fan 2 is located inside the cabinet body 1, and a filter plate 12 is located on top of the cooling fan 2 to filter dust and impurities in the air, extending the service life of the equipment. The fan box 3 is fixedly connected to the top wall of the inner cavity of the cabinet body 1, and the air outlet frame 6 is fixedly connected to the inner wall of the cabinet body 1. One air outlet frame 6 is fixedly connected to the inner wall of the cabinet body 1. In the middle of the cavity, another air outlet frame 6 is fixedly connected to the bottom of the inner cavity of the cabinet 1. The two air outlet frames 6 are at different heights, which achieves the effect of heat dissipation for different areas at the same time, thus improving heat dissipation efficiency. A diverter plate 4 is fixedly connected between the air box 3 and the air outlet frame 6. The air box 3, the diverter plate 4 and the waterproof platform 5 are connected to form an air duct. An air blowing slot 7 is opened inside the air outlet frame 6. A groove 8 is opened through the inside of the cabinet 1. A dustproof net 9 is embedded in the groove 8 to effectively block dust from entering the cabinet 1. A louver 10 is set on the outside of the dustproof net 9 to facilitate air circulation and provide necessary protection to prevent damage to the dustproof net 9. The filter plate 12 covers the top of the cooling fan 2, and the air box 3 is covered on the bottom of the cooling fan 2.

[0032] Reference Figures 3-5 The positioning mechanism includes a slide plate 11, which is fixedly connected to the top of the cabinet 1. The sidewalls of the filter plate 12 are slidably connected between the slide plates 11, allowing the filter plate 12 to move flexibly for easy maintenance and replacement. A sleeve 13 is fixedly connected inside the slide plate 11, and a locking block 16 is provided inside the sleeve 13 to provide positioning during the operation of the filter plate 12. A recess 17 is provided inside the filter plate 12, and the locking block 16 is slidably connected inside the recess 17, ensuring the stability of the filter plate 12 after it has been moved into place. A slider 1 is slidably connected inside the sleeve 13. 4. The locking block 16 is fixedly connected to the side wall of the slider 14. The locking block 16 is slidably connected to the inside of the sleeve 13 through the slider 14. A spring 15 is provided inside the sleeve 13. One end of the spring 15 is fixedly connected to the side wall of the slider 14, and the other end of the spring 15 is fixedly connected to the inside of the sleeve 13, providing a rebound force so that the locking block 16 can automatically reset after the squeezing force is lost. A positioning ring 18 is fixedly connected to the top of the cabinet 1. A top bracket 19 is provided on the top of the cabinet 1. The side wall of the top bracket 19 is slidably connected to the inside of the positioning ring 18, which achieves the effect of blocking rainwater and protecting the cooling fan 2.

[0033] Working principle: When the distribution cabinet is cooling down, the cooling fan 2 is activated to send cool air into the cabinet 1. After the cool air passes through the filter plate 12 to filter dust and impurities, it enters the air box 3, and then enters the air outlet frame 6 at different heights through two diverter plates 4. Finally, it is blown out through the air duct 7, achieving the effect of cooling different areas inside the cabinet 1 simultaneously, thus accelerating the cooling efficiency. After prolonged use, dust will accumulate on the surface of the filter plate 12. At this time, the filter plate 12 needs to be disassembled for cleaning to avoid affecting the air intake. When disassembling the filter plate 12, pull the handle on the outside of the filter plate 12. Handle the filter plate 12 and pull it out from the inside of the slide plate 11. During the pulling process, the locking block 16 will be squeezed and move upward, thereby squeezing the spring 15. When the spring 15 moves out of the recess 17, the filter plate 12 will be unrestrained, and the disassembly can be completed. When installing the filter plate 12 after cleaning, insert the filter plate 12 between the slide plates 11. During the insertion process, the locking block 16 will be squeezed and moved upward. When the recess 17 moves to below the locking block 16, the spring 15 will be unrestrained and pushed by the force to move the locking block 16 downward, locking it inside the recess 17, thereby completing the fixation of the filter plate 12.

Although the present utility model 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.
