Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology for power distribution cabinets, and specifically relates to a power distribution cabinet with a dynamically adjustable heat dissipation structure. Background Technology

[0002] In power systems, distribution cabinets are key equipment for receiving, distributing, and controlling electrical energy, and their stable operation is crucial. With the continuous growth of electricity demand and the increasing integration of electrical equipment, the heat generated by distribution cabinets during operation has increased significantly. For example, in some large data centers, the power supply for numerous servers and other equipment relies on distribution cabinets, and these densely packed electrical components release a large amount of heat when operating.

[0003] Existing distribution cabinets cannot automatically initiate cooling operations based on their internal real-time temperature. When internal heat continues to accumulate and the temperature rises, exceeding the tolerance range of electrical components, it can easily cause damage to the components inside the distribution cabinet due to overheating, thereby affecting the normal function of the entire distribution cabinet. More seriously, excessively high temperatures may cause fires. Once a fire occurs, it will not only burn the distribution cabinet itself, but may also affect surrounding equipment and facilities, causing huge economic losses and even threatening personnel safety.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a power distribution cabinet with a dynamically adjustable heat dissipation structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a power distribution cabinet with a dynamic heat dissipation structure, including a power distribution cabinet body. A partition is fixedly installed in the inner cavity of the power distribution cabinet body. An air outlet shell is fixedly installed on the top of the partition. A circular pipe is connected to the top of the air outlet shell. An air collecting shell is connected to the top of the circular pipe. An arc-shaped air outlet hole is opened on the side wall of the circular pipe. An adjustment mechanism is installed in the inner cavity of the circular pipe. The adjustment mechanism includes a drive motor, an output shaft is fixedly connected to the output end of the drive motor, and a semi-circular block is fixedly installed at the bottom end of the output shaft. The arc of the semi-circular block is greater than the arc of the arc-shaped air outlet. An air guide pipe is installed around the outer periphery of the circular tube. A fixed shell is fixedly installed at the left end of the inner cavity of the power distribution cabinet body. The fixed shell is connected to the air guide pipe. Several air guide mechanisms are rotatably installed at one end of the fixed shell. A power mechanism is engaged at one end of each of the several air guide mechanisms. Several connecting cylinders are installed on the top of the power distribution cabinet body. Semiconductor cooling chips are installed inside each of the several connecting cylinders. A cooling fan is fixedly installed on the top of each of the several connecting cylinders. A temperature detector and a controller are fixedly installed on the inner wall of the power distribution cabinet body.

[0007] Furthermore, the air guiding mechanism includes an air guiding plate, and a rotating shaft is fixedly connected to both the front and rear ends of the air guiding plate. The rotating shaft is rotatably mounted on the fixed shell.

[0008] Furthermore, the rotating shaft at the front end of the air guide plate passes through the fixed shell and extends to the outside, and a gear is fixedly installed at the front end of the rotating shaft.

[0009] Furthermore, the power mechanism includes a telescopic rod, which is fixedly installed on the front of the fixed housing.

[0010] Furthermore, a connecting rod is fixedly installed at the telescopic end of the telescopic rod, and a rack is fixedly installed at the end of the connecting rod away from the telescopic rod.

[0011] Furthermore, the bottom of the power distribution cabinet body is provided with several ventilation holes.

[0012] This utility model has the following beneficial effects: When the temperature inside the distribution cabinet exceeds the normal range, the controller activates the semiconductor cooling chip to cool the cabinet, controls the cooling fan to run at high power, and starts the drive motor to rotate the semi-circular block, thereby opening the arc-shaped air outlet. At the same time, the telescopic rod is activated, which drives the rack to move through the connecting rod. The rack drives several gears and corresponding rotating shafts to rotate, causing all the air guide plates to rotate synchronously and tilt to different angles. This changes the direction of the blown-out cold air and causes it to swing up and down, thereby covering a larger area and quickly spreading to the various electrical components inside the distribution cabinet.

[0019] Please see Figures 1-6 As shown, this utility model is a power distribution cabinet with a dynamic heat dissipation structure, including a power distribution cabinet body 1. A partition 2 is fixedly installed in the inner cavity of the power distribution cabinet body 1. An air outlet shell 3 is fixedly installed on the top of the partition 2. A round pipe 4 is connected to the top of the air outlet shell 3. An air collecting shell 5 is connected to the top of the round pipe 4. An arc-shaped air outlet hole 6 is opened on the side wall of the round pipe 4. An adjustment mechanism 7 is installed in the inner cavity of the round pipe 4. The adjustment mechanism 7 includes a drive motor 701, the output end of which is fixedly connected to an output shaft 702, and a semi-circular block 703 is fixedly installed at the bottom end of the output shaft 702. The arc of the semi-circular block 703 is greater than the arc of the arc-shaped air outlet 6. A duct 8 is installed around the outer periphery of the circular tube 4. A fixed shell 9 is fixedly installed at the left end of the inner cavity of the power distribution cabinet body 1. The fixed shell 9 is connected to the duct 8. A plurality of air guiding mechanisms 10 are rotatably installed at one end of the fixed shell 9. A power mechanism 11 is engaged at one end of each of the air guiding mechanisms 10. A plurality of connecting cylinders 12 are installed on the top of the power distribution cabinet body 1. A semiconductor cooling chip 13 is installed inside each of the connecting cylinders 12. A cooling fan 14 is fixedly installed on the top of each of the connecting cylinders 12. A temperature detector 15 and a controller 16 are fixedly installed on the inner wall of the power distribution cabinet body 1. A plurality of exhaust holes 101 are opened at the bottom of the power distribution cabinet body 1.

[0020] When the temperature detector 15 (model: DS18B20) detects that the temperature inside the distribution cabinet body 1 is within the normal range, the controller 16 will control several cooling fans 14 (model: NF-F12) to start running. The cooling fans 14 blow cold air from the outside into the air collection shell 5 from their respective connecting cylinders 12. The air collection shell 5 will gather this cold air and then guide the gathered cold air into the circular pipe 4. At this time, the semi-circular block 703 is in the state of blocking the arc-shaped air outlet 6, so the cold air entering the circular pipe 4 will all flow into the air outlet shell 3. Several air outlets are opened on the partition 2, and the cold air enters the distribution cabinet body 1 through these air outlets. After exchanging heat with the electrical components, the temperature of the cold air rises and is finally discharged to the outside from several exhaust holes 101 at the bottom of the distribution cabinet body 1. When the temperature detector 15 detects that the temperature inside the distribution cabinet 1 exceeds the normal range, it will immediately transmit the detection data to the controller 16. The controller 16 will simultaneously perform several operations: first, it will control the semiconductor cooling chips 13 (model: TEC3-19912) inside several connecting cylinders 12 to start cooling and cool the incoming air; second, it will control several cooling fans 14 to operate in high-power mode to increase the air delivery volume; and third, it will control the drive motor 701 (model: NEMA) to operate in high-power mode. 23) Upon startup, the drive motor 701 drives the output shaft 702 to rotate, and the semi-circular block 703 rotates synchronously with the output shaft 702 until the semi-circular block 703 switches from its original position blocking the arc-shaped air outlet 6 to the other side of the arc-shaped air outlet 6, making the arc-shaped air outlet 6 fully open. At this time, the circular pipe 4 is connected to the air guide pipe 8, and the cold air entering the circular pipe 4 will be divided into two paths: one path continues to enter the air outlet shell 3 through the circular pipe 4, and the other path enters the air guide pipe 8 through the arc-shaped air outlet 6. The cold air entering the air guide pipe 8 is guided into the fixed shell 9. At the same time, the controller 16 also controls the power mechanism 11. During operation, the power mechanism 11 drives several air guide mechanisms 10 to rotate on the fixed shell 9. The cold air blown out from the fixed shell 9 will change its airflow direction under the guidance of the air guide mechanisms 10. The power mechanism 11 continuously drives the air guide mechanisms 10 to rotate back and forth, which can make the cold air blown into the distribution cabinet body 1 constantly switch up and down directions, so that the cold air can quickly diffuse into the distribution cabinet body 1, thereby quickly reducing the temperature inside the distribution cabinet body 1 and restoring it to the normal range. This effectively avoids the risk of component damage, fire and other risks caused by excessive temperature, and thus realizes dynamic control of the temperature inside the distribution cabinet body 1. It is important to note that temperature detectors 15 can be installed at different heights within the distribution cabinet body 1. These temperature detectors 15 will monitor the temperature of their respective height areas in real time and continuously transmit the data to the controller 16. When a temperature detector 15 at a certain height detects that the temperature in that area exceeds the normal value and is significantly higher than the temperature in other height areas, the controller 16 will locate the high-temperature area by comparing and analyzing the data transmitted by each temperature detector 15. At this time, the controller 16 will send a control command to the power mechanism 11, which will then drive several air guide mechanisms 10 to rotate and adjust. By adjusting the angle of the air guide mechanisms 10, the cold air blown from the fixed shell 9 can be directed towards the high-temperature area, allowing the cold air to be preferentially delivered to the higher-temperature area and quickly exchange heat with that area, thereby achieving targeted and preferential cooling of the high-temperature area.

[0021] In one embodiment, the air guiding mechanism 10 includes an air guiding plate 1001, and a rotating shaft 1002 is fixedly connected to both the front and rear ends of the air guiding plate 1001. The rotating shaft 1002 is rotatably mounted on the fixed shell 9.

[0022] The rotating shaft 1002 at the front end of the air guide plate 1001 passes through the fixed shell 9 and extends to the outside, and a gear 1003 is fixedly installed at the front end of the rotating shaft 1002.

[0023] The power mechanism 11 includes a telescopic rod 1101, which is fixedly installed on the front of the fixed housing 9.

[0024] A connecting rod 1102 is fixedly installed at the telescopic end of the telescopic rod 1101, and a rack 1103 is fixedly installed at the end of the connecting rod 1102 away from the telescopic rod 1101.

[0025] When the temperature detector 15 inside the distribution cabinet detects a local temperature anomaly, the controller 16 controls the telescopic rod 1101 (model YNT-05) to start. The telescopic end of the telescopic rod 1101 drives the connecting rod 1102 to perform linear reciprocating motion. The rack 1103 on the connecting rod 1102 moves synchronously. The rack 1103 meshes with multiple gears 1003. The linear motion of the rack 1103 is converted into the rotational motion of the rotating shaft 1002 through the transmission of the gears 1003. This drives all the air guides 1001 to rotate synchronously on the fixed shell 9. When the air guides 1001 tilt at different angles, the direction of the cold air blown out from the fixed shell 9 changes accordingly, forming an up-and-down swinging air outlet effect. This allows the cold air to cover a larger area and quickly diffuse to the various electrical components inside the distribution cabinet body 1, thereby cooling the electrical components and restoring the temperature inside the distribution cabinet body 1 to normal. This, in turn, regulates the temperature inside the distribution cabinet body 1.

[0026] Working principle: When the temperature detector 15 detects that the temperature inside the distribution cabinet body 1 is within the normal range, several cooling fans 14 operate. The cooling fans 14 blow cold air from the outside into the air collection shell 5 from the connecting cylinder 12, and then guide the cold air into the round pipe 4. At this time, the semi-circular block 703 is in the state of blocking the arc-shaped air outlet 6, so the cold air entering the round pipe 4 will all flow into the air outlet shell 3. The cold air enters the distribution cabinet body 1 through several air outlets on the air outlet shell 3. After heat exchange with the electrical components, the temperature of the cold air rises, and finally it is discharged to the outside from several exhaust holes 101 at the bottom of the distribution cabinet body 1. When the temperature detector 15 detects that the temperature inside the distribution cabinet body 1 exceeds the normal range, the controller 16 controls the semiconductor cooling chip 13 to start cooling, also controls several cooling fans 14 to operate in high-power mode, and controls the drive motor 701 to start. The drive motor 701 drives the output shaft 702 to rotate, and the semi-circular block 703 rotates synchronously with the output shaft 702. The arc-shaped air outlet 6 is fully opened, and the cold air entering the circular pipe 4 is split into two paths: one continues to enter the air outlet shell 3 through the circular pipe 4, and the other enters the air guide pipe 8 through the arc-shaped air outlet 6. The cold air entering the air guide pipe 8 flows into the fixed shell 9. At the same time... The controller 16 controls the telescopic rod 1101 to start, and the telescopic end of the telescopic rod 1101 drives the connecting rod 1102 to make linear reciprocating motion. The connecting rod 1102 drives the rack 1103 to move, and the rack 1103 drives several gears 1003 and the corresponding rotating shafts 1002 to rotate, thereby driving all the air guide plates 1001 to rotate synchronously on the fixed shell 9. When the air guide plates 1001 are tilted at different angles, the direction of the cold air blown out from the fixed shell 9 changes accordingly, forming an up-and-down swinging air outlet effect, so that the cold air can cover a larger area and quickly diffuse to the various electrical components in the power distribution cabinet body 1.
