Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a heat dissipation structure. Background Art

[0002] The distribution cabinet is a relatively common circuit protection device, which is often used in different occasions such as factories and buildings. When the distribution cabinet is in continuous use, the temperature of the circuit components inside the distribution cabinet will rise, thereby increasing the temperature inside the distribution cabinet. When the temperature inside the distribution cabinet is high, it will affect the service life of the circuit components.

[0003] The heat dissipation methods of distribution cabinets mainly include natural heat dissipation, forced air cooling and water cooling. Natural heat dissipation refers to transferring heat from the inside of the distribution cabinet to the external environment by natural convection through the heat dissipation ports and air ducts opened on the distribution cabinet. Natural heat dissipation is safe and reliable, with low energy consumption, but the heat dissipation efficiency is low; forced air cooling is to force the circulation of external air through forced fans or other mechanical equipment to accelerate the heat dissipation inside the distribution cabinet. Forced air cooling has high heat dissipation efficiency and a wide range of applications, but it is noisy and the equipment is easily damaged; water cooling is to introduce cooling water into the inside of the distribution cabinet and use the cooling effect of water to reduce the temperature inside the distribution cabinet. Water cooling has high heat dissipation efficiency, but the cooling system inside the distribution cabinet is more complicated to maintain. Utility Model Content

When the distribution cabinet body 2 is in operation, the heat sink 3 and multiple heat sink fins 4 fixedly installed on the distribution cabinet body 2 dissipate the heat generated by the fixing seat 1, and at the same time start the water pump 5. The water pump 5 pumps the water in the water tank 8 into the cooling pipe 7 through the water inlet pipe 6. The cooling pipe 7 accelerates the speed of heat loss when the heat sink 3 and the heat sink fins 4 dissipate heat, and plays a role in auxiliary heat dissipation. The water in the cooling pipe 7 flows downward from the top position of the heat sink 3, and finally flows into the water tank 8 through the water inlet channel 9. The heated water is cooled in the water tank 8 and continues to be recycled through the water pump 5, etc. By arranging the water pump 5 and the water tank 8, etc. on the outside of the distribution cabinet body 2 to assist the heat dissipation of the heat sink 3 and the heat sink fins 4, the heat dissipation efficiency of the distribution cabinet body 2 is improved, and the water pump 5 and the water tank 8, etc. arranged on the outside of the distribution cabinet body 2 are convenient for maintenance, which reduces the tediousness of maintenance work.

[0026] Furthermore, a plurality of cooling plates 13 are fixedly installed in the water tank 8. The cooling plates 13 are inclined and arranged in sequence from top to bottom from the end of the water inlet channel 9 to the end of the water outlet channel 10. A plurality of grooves 14 are provided on the cooling plates 13. Water falling into the water tank 8 from the water inlet channel 9 flows downward from the plurality of cooling plates 13 in sequence. The plurality of grooves 14 on the cooling plates 13 also increase the surface area of ​​the cooling plates 13. The water can dissipate heat during the flow, thereby cooling the water.

[0028] Furthermore, an interception net (not shown in the figure) is fixedly installed on the inner wall of the water outlet channel 10; the interception net can prevent the debris in the water tank 8 from being pumped into by the water pump 5, thereby avoiding damage to the water pump 5.

[0029] Furthermore, a motor 16 is fixedly installed on the outside of the water tank 8, and the output end of the motor 16 penetrates the side wall of the water tank 8 and is fixedly connected to the main bevel gear 17. A rotating shaft 18 is rotatably installed in the water tank 8, and a slave bevel gear 19 is fixedly installed at the bottom of the rotating shaft 18. The main bevel gear 17 is meshed with the slave bevel gear 19. A conveying blade 20 is fixedly installed on the rotating shaft 18, and a water delivery pipe 21 is fixedly installed on the inner wall of the water tank 8.

When the conveying blade 20 rotates, the water in the water tank 8 is transported from the water pipe 21 to the top of the cooling plate 13, so that the water flowing down the cooling plate 13 can flow again, thereby accelerating the cooling speed of the water in the water tank 8.

[0030] The working principle of the device is as follows: when the power distribution cabinet body 2 is in operation, the heat sink 3 and multiple heat sink fins 4 fixedly installed on the power distribution cabinet body 2 dissipate the heat generated by the fixing seat 1, and at the same time start the water pump 5, and the water pump 5 pumps the water in the water storage tank 8 into the cooling pipe 7 through the water inlet pipe 6. The cooling pipe 7 accelerates the speed of heat loss when the heat sink 3 and the heat sink fins 4 dissipate heat, and plays a role in auxiliary heat dissipation. The water in the cooling pipe 7 flows downward from the top position of the heat sink 3, and finally flows into the water storage tank 8 through the water inlet channel 9, and the motor 16 is started. The output end of the motor 16 drives the main bevel gear 17 to rotate. The main bevel gear 17 drives the rotating shaft 18 and the conveying blade 20 to rotate through the meshing transmission of the slave bevel gear 19. When the conveying blade 20 rotates, the water in the water tank 8 is transported from the water pipe 21 to the top of the cooling plate 13, so that the water flowing down through the cooling plate 13 can flow repeatedly, thereby accelerating the cooling speed of the water in the water tank 8. By arranging a water pump 5 and a water tank 8 on the outside of the distribution cabinet body 2 to assist the heat dissipation of the heat sink 3 and the heat dissipation fins 4, the heat dissipation efficiency of the distribution cabinet body 2 is improved, and the water pump 5 and the water tank 8 arranged on the outside of the distribution cabinet body 2 are convenient for maintenance, thereby reducing the complexity of maintenance work.
