Description

Technical Field

[0001] This utility model relates to the field of power distribution control cabinet technology, specifically to a high-efficiency heat dissipation power distribution control cabinet. Background Technology

[0002] A power distribution control cabinet is a complete set of electrical equipment that integrates power distribution, equipment control, and safety protection functions. It is a key hub connecting the power supply system and end-user loads, and is widely used in industrial production, buildings, and municipal facilities. Its main body is a metal cabinet that meets IP protection standards. Internal core components include control elements such as circuit breakers, contactors, and relays; overload, short-circuit, and leakage protection components; current / voltage monitoring instruments; wiring terminals; and wiring assemblies.

[0003] Currently, existing power distribution control cabinets often require heat dissipation to prevent excessive internal temperature during use. Existing heat dissipation methods mostly involve creating heat dissipation slots in the cabinet walls or using fans for ventilation. However, for sealed power distribution control cabinets that require waterproofing and moisture protection, it is often necessary to ensure that the cabinet is sealed, making it difficult to achieve effective heat dissipation. As a result, the heat inside the cabinet continuously accumulates and rises, which greatly affects safety. Therefore, this application proposes a high-efficiency heat dissipation power distribution control cabinet. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency heat dissipation power distribution control cabinet. By setting an air intake pipe inside the cabinet, with the cooperation of support blocks and drive components, the support blocks can drive the air intake pipe to rise and fall stably in a straight line, so that the air intake pipe can completely draw in the hot air emitted around the electrical components on each layer. Furthermore, by setting a ventilation mechanism and a blowing pipe, the ventilation mechanism is composed of a heat exchange box and heat exchange components, which can quickly and effectively dissipate and cool the hot air. The hot air enters the blowing pipe after heat exchange in the heat exchange box, and then blows upwards through the blowing holes onto the electrical components on the mounting bracket. Under the action of this structure, the hot air can be circulated and cooled, thereby ensuring that the cabinet is sealed and moisture-proof while achieving high-efficiency heat dissipation. The performance is good, thus solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation power distribution control cabinet, comprising: The cabinet has a fixed base at its bottom and an installation rack inside. Inside the cabinet, near the mounting frame, a threaded rod is rotatably connected via a bearing. A drive assembly is located at the bottom of the threaded rod, and a support block is threadedly connected to its exterior. One end of the support block is fixed with an air intake pipe facing the mounting frame, and multiple air intake holes are located on the side wall of the air intake pipe. One end of the air intake pipe is connected to an air delivery hose. Inside the cabinet, at the bottom end near the mounting frame, an air blowing pipe is located. Multiple air blowing holes are located on the top side of the air blowing pipe, and one end of the air blowing pipe is connected to a second connecting pipe. A ventilation mechanism is provided between the air delivery hose and the second connecting pipe.

[0006] Preferably, the drive assembly includes a drive motor fixedly connected to the bottom of the cabinet near the threaded rod, the output end of the drive motor is connected to a first bevel gear, and the bottom end of the threaded rod is fixed with a second bevel gear that meshes perpendicularly with the first bevel gear.

[0007] Preferably, limit blocks are provided at both ends of the air intake pipe, and limit grooves matching the limit blocks are provided on both sides of the interior of the cabinet.

[0008] Preferably, the ventilation mechanism includes a heat exchange box and an air pump installed in a fixed base. The heat exchange box is equipped with heat exchange components.

One end of the first connecting pipe extends into the cabinet and is connected to the air supply hose. One end of the second connecting pipe extends into the fixed base and is connected to the heat exchange box. The second connecting pipe and the air pump are connected opposite to each other at both ends of the heat exchange box.

[0009] Preferably, the heat exchange assembly includes multiple heat-conducting plates arranged in an array on both sides inside the heat exchange box, with a wave-shaped heat dissipation channel formed between the multiple heat-conducting plates, and one end of each of the multiple heat-conducting plates extending outside the heat exchange box and connected to heat dissipation fins.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By installing an air intake pipe inside the cabinet, and with the cooperation of support blocks and drive components, the support blocks can drive the air intake pipe to rise and fall stably in a straight line.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figures 1-5 The high-efficiency heat dissipation power distribution control cabinet shown includes: Cabinet 1, with a fixed base 2 at the bottom and a mounting bracket 3 inside the cabinet 1; Inside the cabinet 1, near the mounting bracket 3, a threaded rod 7 is rotatably connected via a bearing. A drive assembly is located at the bottom of the threaded rod 7, and a support block 4 is threadedly connected to the outside of the threaded rod 7. One end of the support block 4 is fixed with an air intake pipe 5 facing the mounting bracket 3, and the side wall of the air intake pipe 5 has multiple air intake holes 6. Furthermore, limit blocks 11 are provided at both ends of the air intake pipe 5. Limiting grooves 12 matching the limit blocks 11 are provided on both sides of the inside of the cabinet 1. By setting the limit blocks 11 and... The limiting groove 12 allows the suction pipe 5 to move the limiting block 11 along the limiting groove 12, thereby further supporting and limiting it to ensure that the suction pipe 5 rises and falls stably in a straight line. One end of the suction pipe 5 is connected to the air supply hose 13. An air blowing pipe 18 is provided on the bottom side of the cabinet 1 near the mounting bracket 3. Multiple air blowing holes 19 are provided on the top side of the air blowing pipe 18, and one end of the air blowing pipe 18 is connected to the second connecting pipe 17. A ventilation mechanism is provided between the air supply hose 13 and the second connecting pipe 17.

[0017] In this embodiment, the drive assembly includes a drive motor 8 fixedly connected to the bottom of the cabinet 1 near the threaded rod 7. The output end of the drive motor 8 is connected to a first bevel gear 9, and the bottom end of the threaded rod 7 is fixed with a second bevel gear 10 that meshes perpendicularly with the first bevel gear 9. Based on this, by starting the drive motor 8, the drive motor 8 can drive the first bevel gear 9 to rotate, and then the first bevel gear 9 drives the second bevel gear 10 to rotate, which in turn drives the threaded rod 7 to rotate.

[0018] In one specific embodiment of this utility model, the ventilation mechanism includes a heat exchange box 16 and an air pump 14 disposed in a fixed base 2. The heat exchange box 16 is provided with a heat exchange assembly, which includes multiple heat-conducting plates 21 arranged in an array on both sides inside the heat exchange box 16. A wave-shaped heat dissipation channel is formed between the multiple heat-conducting plates 21, and one end of each of the multiple heat-conducting plates 21 extends to the outside of the heat exchange box 16 and is connected to a heat dissipation fin 22. One end of the air pump 14 is provided with a first connecting pipe 15, and the other end of the air pump 14 is connected to the heat exchange box 16 through a pipe. One end of the first connecting pipe 15 extends into the cabinet 1 and is connected to the air supply hose 13. One end of the second connecting pipe 17 extends into the fixed base 2 and is connected to the heat exchange box 16, and the second connecting pipe 17 is connected to the air pump 14 at both ends of the heat exchange box 16.

[0019] By activating the air pump 14 to generate suction, the suction can be delivered to the air intake pipe 5 through the first connecting pipe 15 and the air supply hose 13. Then, the air intake pipe 5 can draw out the hot air emitted around the electrical components on each layer of the mounting frame 3 through the air intake hole 6. By activating the drive assembly, the drive assembly can control the rotation of the threaded rod 7, so that the threaded rod 7 drives the support block 4 to move. With the cooperation of the limit block 11 and the limit groove 12, the support block 4 can drive the air intake pipe 5 to rise and fall steadily in a straight line, so that the air intake pipe 5 can completely draw away the hot air around the electrical components on each layer of the mounting frame 3. Afterwards, hot air can enter the heat exchange box 16 through the air delivery hose 13 and the first connecting pipe 15, so that the hot air interacts with the heat conduction plate 21 inside the heat exchange box 16. The heat can be quickly conducted to the heat dissipation fins 22 through the heat conduction plate 21, thereby dissipating the heat to the outside of the box. Since multiple sets of heat conduction plates 21 form a wave-shaped heat dissipation channel, the hot air can circulate in the wave-shaped heat dissipation channel to fully contact the heat conduction plate 21 and extend the heat dissipation path. At the same time, with the operation of the fan 24 in the air duct 23, the heat on the heat dissipation fins 22 can be blown to the outside of the cabinet 1 through the ventilation slot 20. After being cooled by heat dissipation, the air can enter the air blowing pipe 18 through the second connecting pipe 17, and then blow upwards through the air blowing hole 19 onto the electrical components on the mounting bracket 3. Under the action of this structure, the hot air can be circulated for heat dissipation and cooling, thereby ensuring that the cabinet 1 is sealed and moisture-proof while achieving efficient heat dissipation and good performance.

[0020] One end of the fixed base 2 is provided with a wind duct 23 facing the heat exchange box 16, and the other end of the fixed base 2 is provided with multiple sets of ventilation slots 20. A fan 24 is provided inside the wind duct 23, and a filter plate 25 is provided at the port of the wind duct 23. The filter plate 25 can prevent dust or insects and rodents from entering the wind duct 23.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
