Description

Technical Field

[0001] This utility model relates to the field of explosion-proof motor technology, and in particular to an explosion-proof motor with an external heat dissipation component. Background Technology

[0002] Explosion-proof motors are a type of motor that can be used in flammable and explosive environments without producing electrical sparks during operation. They are widely used in flammable and explosive environments such as chemical plants, petroleum plants, and mines, where safety and reliability are paramount. Because explosion-proof motors typically employ a closed structure to prevent spark leakage, internal heat is difficult to dissipate quickly. Prolonged operation at high temperatures can easily lead to insulation aging, reduced efficiency, and even equipment failure. Therefore, external heat dissipation components are generally used for cooling.

[0003] Existing external heat dissipation components for explosion-proof motors typically include heat sink fins and a fan, utilizing forced convection to enhance heat dissipation. The fan's exhaust direction is usually aligned with the length of the heat sink fins, meaning the airflow runs along the length of the fins. While this design enhances airflow, a significant temperature gradient forms between the air inlet and outlet ends of the heat sink fins as the air moves, leading to uneven heat dissipation. The heat sink fins closer to the air inlet have lower temperatures and better heat dissipation, while those farther from the air inlet experience decreased heat dissipation efficiency due to the gradually increasing air temperature, affecting overall heat dissipation performance. Therefore, an explosion-proof motor with an external heat dissipation component is proposed. Utility Model Content

The air duct 5 includes a pipe body 501 fixedly connected to the left side of the fixed housing 4, and first air outlets 502 are provided at the top and bottom of the left side of the inside of the pipe body 501, and first air outlets 502 are provided at the top and bottom of the middle of the inside of the pipe body 501. There is a second air outlet 503, and a third air outlet 504 is provided on the upper and lower right sides of the inside of the tube body 501. The tube body 501 is located between adjacent heat sinks 102. The first air outlet 502, the second air outlet 503, and the third air outlet 504 on the upper part of the tube body 501 are aligned with the lower part of the corresponding heat sink 102, and the first air outlet 502, the second air outlet 503, and the third air outlet 504 on the upper and lower parts of the tube body 501 are aligned with the upper part of the corresponding heat sink 102. In use, the drive motor 201 is started so that the rotating shaft 202 can drive the main... The driving gear 203 rotates, meshing with the driven gear 306. The rotation of the driving gear 203 causes the driven gear 306 to drive the outer cylinder 305 to rotate, which in turn drives the fan blades 304 to rotate. The rotation of the fan blades 304 generates airflow, which enters the pipe body 501 and exits through the first air outlet 502, the second air outlet 503, and the third air outlet 504. The first air outlet 502 is tilted to the left, allowing the air to reach the heat sink 102 and move to the left, facilitating even heat dissipation. The left half of the heat sink 102 is used for heat dissipation. The third air outlet 504 is tilted to the right so that the air can blow onto the heat sink 102 and move to the right, which facilitates uniform heat dissipation of the right half of the heat sink 102. The second air outlet 503 is vertically set so that the air can blow onto the middle part of the heat sink 102, making the temperature of the air in contact with each area of ​​the heat sink 102 more uniform, which facilitates uniform heat dissipation of the heat sink 102, and thus more uniform heat dissipation of the explosion-proof motor 1, ensuring better overall heat dissipation performance.

[0022] Furthermore, the explosion-proof motor 1 includes a motor body 101, a drive shaft 103 fixedly connected to the output end of the motor body 101, a base 104 fixedly connected to the lower part of the motor body 101, the base 104 is used to support the motor body 101, the lower part of the base 104 is provided with mounting holes to facilitate fixing the base 104 on a plane, and a heat sink 102 fixedly connected to the outer side of the motor body 101. The heat sink 102 is made of copper and has high thermal conductivity, which can quickly conduct heat from inside the motor body 101 and dissipate it into the air.

[0023] Furthermore, the drive device 2 includes a drive motor 201 fixedly connected to the top of the explosion-proof motor 1. A rotating shaft 202 is fixedly connected to the output end of the drive motor 201. A drive gear 203 is fixedly connected to the outer side of the rotating shaft 202. The drive gear 203 meshes with the driven gear 306. By starting the drive motor 201, the rotating shaft 202 can drive the drive gear 203 to rotate, thereby causing the driven gear 306 to rotate.

[0024] Furthermore, the fan 3 includes an outer bearing 301 fixedly connected to the inner side of the fixed housing 4 and an inner bearing 302 fixedly connected to the right side of the outer side of the explosion-proof motor 1. The arrangement of the outer bearing 301 and the inner bearing 302 allows the outer cylinder 305, the fan blade 304, and the inner cylinder 303 to rotate more easily. The outer cylinder 305 is fixedly connected to the inner side of the outer bearing 301, and the inner cylinder 303 is fixedly connected to the outer side of the inner bearing 302. The fan blade 304 is fixedly connected between the inner cylinder 303 and the outer cylinder 305. The fan blade 304 is obliquely arranged between the inner cylinder 303 and the outer cylinder 305. The rotation of the fan blade 304 can drive the airflow and generate wind. The driven gear 306 is fixedly connected to the outer side of the outer cylinder 305. The rotation of the driven gear 306 can drive the fan blade 304 to rotate.

[0025] Furthermore, the fixed housing 4 includes a housing 401 fixedly connected to the right side of the explosion-proof motor 1. A fixing hole 402 is provided on the left side of the housing 401 for fixing the tube body 501. An upper housing 404 is fixedly connected to the top of the housing 401. A rotating hole 403 is provided inside the upper housing 404 for rotating the shaft 202. A through hole 406 is provided on the top of the housing 401 for the passage of the drive gear 203, allowing the drive gear 203 to contact the driven gear 306. A rear cover 407 is fixedly connected to the right side of the housing 401. A sealing block 405 is threadedly connected to the top of the rear cover 407 for sealing the interior of the rear cover 407. The interior of the rear cover 407 has a receiving cavity 410. Unscrewing the sealing block 405 allows coolant to be introduced into the receiving cavity 410. An air inlet 408 is fixedly connected inside the rear cover 407, and an inner heat-conducting plate 411 is fixedly connected inside the air inlet 408. An outer heat-conducting plate 409 is fixedly connected to the outside of the rear cover 407. When the fan blade 304 pushes air into the housing 401, the air first passes through the air inlet 408. Under the action of the inner heat-conducting plate 411, the temperature of the coolant in the receiving cavity 410 can be introduced into the inner heat-conducting plate 411, which can cool the air entering the housing 401 through the air inlet 408, thereby making the temperature of the air discharged from the pipe 501 even lower, further accelerating the heat dissipation efficiency. The outer heat-conducting plate 409 is used to dissipate heat from the coolant to ensure that the temperature of the coolant does not become too high.

[0026] Furthermore, the first air outlet 502 is tilted to the left, the second air outlet 503 is vertical, and the third air outlet 504 is tilted to the right. By setting the air outlets with different air outlet directions, the temperature of the air contacted by each area of ​​the heat sink 102 is more uniform, ensuring better overall heat dissipation performance.
