Description
Technical Field
[0001] This utility model relates to the technical field of reactor heat dissipation equipment, specifically a heat dissipation device for reactors. Background Technology
[0002] A reactor, also called an inductor, is a conductor that generates a magnetic field within a certain space when current flows through it. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long, straight conductor is relatively small, and the magnetic field it generates is not strong. Therefore, actual reactors are made by winding wires into a solenoid shape, called air-core reactors. Reactors are generally installed in reactor boxes and reactor shells. As a result, a large amount of heat is generated inside the reactor box, so a heat dissipation device is needed to dissipate the heat.
[0003] However, existing heat dissipation devices for reactors typically use ambient temperature air from outside to cool the reactor tank, which cannot effectively ensure that the air blown out by the heat dissipation device is cold air, resulting in poor heat dissipation of the reactor. Therefore, we propose a heat dissipation device for reactors. Utility Model Content
[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a heat dissipation device for reactors. A heat dissipation frame is installed on the reactor's outer casing, which has a groove. The heat dissipation frame is located inside the groove. A drive assembly is activated to operate a second rotating shaft, which in turn rotates a second fan blade. This rotation creates a negative pressure inside the heat dissipation frame, drawing in external air. Simultaneously, a water pump operates, pumping cold water from a water tank into a water collection chamber. Through the evenly distributed drain holes, the water is evenly sprayed onto multiple layers of wet curtain paper. The external air, through the heat absorption of the cold water, is expelled into the reactor, improving heat dissipation. The cold water is then discharged through the through-holes, drain chamber, and drain holes for reuse after cooling, improving resource utilization and effectively solving the problems in the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat dissipation device for a reactor, comprising a heat dissipation frame, an enclosure frame, a uniform airflow assembly, and a drive assembly;

Multiple second fan blades are installed on the outside of the second rotating shaft. Slots are formed in the middle of the four sides of the front of the heat dissipation frame. Blocks are installed in the middle of the outer surfaces of the four sides of the enclosure frame. The blocks and slots are connected by snap-fit. Multiple layers of wet curtain paper are evenly arranged inside the enclosure frame. A drainage cavity is formed inside the lower end of the enclosure frame. Multiple... The drainage chamber has a through hole, and a drainage hole is provided on the inner front wall of the drainage chamber. A plunger is snapped into the drainage hole.

The outer end of the water pipe is snapped into the water inlet. An air distribution component is installed at the rear of the heat dissipation frame.
[0007] Furthermore, the air distribution assembly includes a second gear mounted on a second rotating shaft. Multiple exhaust slots are evenly distributed on the second gear. Two fixed plates are mounted on the rear side of the heat dissipation frame. First rotating shafts are rotatably mounted on both sides of the fixed plates. A first gear is mounted on the rear end of each first rotating shaft. The first and second gears are meshed together. A drive assembly is mounted on the left side of the upper fixed plate. The drive assembly is connected to a first rotating shaft. Multiple first fan blades are evenly distributed on the front end of the first rotating shaft. The drive assembly drives the first rotating shaft to rotate, which in turn drives the first gear connected to it to rotate. The first gear drives the second gear to rotate, which in turn drives the other first gears to rotate. This rotation of the second gear drives the second rotating shaft to rotate the second fan blades. The rotation of the other first gears drives the other first rotating shafts to rotate, thereby rotating the first fan blades connected to them. This evenly distributes the cool air supplied to the reactor, further improving the heat dissipation effect on the reactor.
[0008] Furthermore, the drive assembly includes a motor bracket mounted on the front side of the upper fixed plate, on which a motor is mounted. The output shaft of the motor is connected to one end of a first rotating shaft via a coupling, and the input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor to operate, and the motor drives the first rotating shaft to rotate, thereby completing the rotation of the first rotating shaft electrically.
[0009] Furthermore, it also includes mounting plates and mounting holes. Mounting plates are installed on both the upper and lower surfaces of the heat sink frame, and mounting holes are provided on the mounting plates. The heat sink frame is installed on the reactor housing through the mounting plates and mounting holes.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the heat dissipation device for reactors has a heat dissipation frame installed on the reactor's outer casing. The reactor's outer casing has a groove, and the heat dissipation frame is located inside the groove. The drive assembly is activated to operate the second rotating shaft, which in turn drives the second fan blades. This rotation of the second fan blades creates a negative pressure inside the heat dissipation frame, drawing in external air. Simultaneously, a water pump operates, pumping cold water from the water tank into the water collection chamber through a water pipe. Under the action of the uniform drain holes, the water is evenly sprayed onto multiple layers of wet curtain paper. The external air, through the heat absorption of the cold water, is expelled into the reactor's interior, thus improving the heat dissipation effect. The cold water is discharged to the outside through the through-holes, drain chamber, and drain holes, allowing it to be recycled after cooling, thereby improving resource utilization.

[0017] In use, the heat sink 1 is installed on the outer shell of the reactor. The outer shell of the reactor has a groove, and the heat sink 1 is located inside the groove. The second rotating shaft 21 is driven by the start-up drive assembly. The rotation of the second rotating shaft 21 drives the second fan blade 20 to rotate, thereby creating a negative pressure inside the heat sink 1 through the rotation of the second fan blade 20, which draws external air into the heat sink 1. At this time, the water pump 3 works to input cold water from the water tank 2 into the water collection chamber through the water pipe 4. Under the action of the uniform drain hole, it is evenly sprayed onto the multi-layer wet curtain paper 9. The external air is cooled by the heat absorption effect of the cold water and discharged into the interior of the reactor to improve the heat dissipation effect of the reactor. The cold water is discharged to the outside through the through hole 11, the drain chamber and the drain hole, so that it can be recycled after cooling and improve the utilization rate of resources.
[0018] The air distribution assembly includes a second gear 15 mounted on a second rotating shaft 21. Multiple exhaust slots 16 are evenly distributed on the second gear 15. Two fixing plates 22 are mounted on the rear side of the heat dissipation frame 1. A first rotating shaft 18 is rotatably mounted on both sides of the fixing plate 22. A first gear 12 is mounted on the rear end of the first rotating shaft 18. The first gear 12 and the second gear 15 are meshed together. A drive assembly is mounted on the left side of the upper fixing plate 22. The drive assembly is connected to a first rotating shaft 18. Multiple first fan blades 19 are evenly distributed on the front end of the first rotating shaft 18. The drive assembly rotates a first shaft 18, which in turn rotates a first gear 12 connected to it. The first gear 12 rotates, which in turn rotates a second gear 15. The second gear 15 rotates, which in turn rotates other first gears 12. This rotation of the second gear 15 then rotates the second shaft 21, which rotates the second fan blade 20. The rotation of the other first gears 12 rotates the other first shafts 18, which in turn rotate the first fan blade 19 connected to them. This distributes the cool air supplied to the reactor evenly throughout the reactor, further improving the heat dissipation effect.
[0019] The drive assembly includes a motor bracket 13 mounted on the front side of the upper fixed plate 22. A motor 14 is mounted on the motor bracket 13. The output shaft of the motor 14 is connected to one end of a first rotating shaft 18 via a coupling. The input end of the motor 14 is electrically connected to the output end of an external controller. The external controller controls the operation of the motor 14, which drives the first rotating shaft 18 to rotate, thereby completing the rotation of the first rotating shaft 18 electrically.
[0020] It also includes mounting plates 5 and mounting holes 6. Mounting plates 5 are installed on both the upper and lower surfaces of the heat sink frame 1, and mounting holes 6 are provided on the mounting plates 5. The heat sink frame 1 is installed on the outer casing of the reactor through the mounting plates 5 and mounting holes 6.

The outer shell of the reactor has a groove, and the heat dissipation frame 1 is located inside the groove. By starting the drive assembly, the second rotating shaft 21 is driven to work. The rotation of the second rotating shaft 21 drives the second fan blade 20 to rotate, thereby creating a negative pressure inside the heat dissipation frame 1 through the rotation of the second fan blade 20, which draws external air into the heat dissipation frame 1. At this time, the water pump 3 works to input cold water from the water tank 2 into the water collection chamber through the water pipe 4. Under the action of the uniform drain hole, it is evenly sprinkled onto the multi-layer wet curtain paper 9. The external air is cooled by the heat absorption effect of the cold water and discharged into the interior of the reactor to improve the heat dissipation effect of the reactor. The cold water is discharged to the outside through the through hole 11, the drain chamber and the drain hole so that it can be recycled after cooling and improve the utilization rate of resources. The drive assembly rotates a first shaft 18, which in turn rotates a first gear 12 connected to it. The first gear 12 then rotates a second gear 15, which in turn rotates other first gears 12. This rotation of the second gears 15 drives a second shaft 21, rotating the second fan blade 20. The other first gears 12 rotate other first shafts 18, which in turn rotate the first fan blade 19 connected to them. This distributes the cool air entering the reactor evenly throughout, further improving the reactor's heat dissipation. An external controller controls a motor 14, which rotates the first shaft 18 electrically. The heat sink 1 is mounted on the reactor's casing using a mounting plate 5 and mounting holes 6.
