Description

Technical Field

[0001] This invention relates to the technical field of industrial applications, and more specifically, to a water-cooling mechanism for a fan motor. Background Technology

[0002] In the industrial field, a fan is a device that converts mechanical energy into airflow energy. It is widely used in ventilation, exhaust, air supply, dust removal and other processes in industrial production. The high efficiency and continuous operation of the fan motor makes it highly dependent on the heat dissipation system. In the existing technology, the water cooling of the motor mostly adopts the circulating water cooling solution, that is, water pipes are immersed in water tanks to form a water circulation channel, and the flowing cold water is used to remove the heat generated by the motor operation.

[0003] While this solution can achieve basic heat dissipation, it has significant limitations. First, as the water temperature continues to rise during water circulation, the system's heat exchange efficiency gradually decreases. When the temperature difference between the water and the motor surface narrows, the heat dissipation effect is almost ineffective. Second, fans are often used in complex environments such as mines and tunnels, where the motor body easily adsorbs a large amount of dust, fibers, and other pollutants. The accumulated dust layer forms a heat insulation barrier, hindering heat conduction between the water cooling system and the motor surface, further exacerbating the risk of local overheating. If such dust accumulation is not cleaned in time, it will not only reduce heat dissipation efficiency but may also cause insulation aging, mechanical component wear, or even short circuit failure due to long-term high-temperature operation of the motor, thus hindering practical use. Summary of the Invention

[0004] To address the issues raised in the background art, such as the gradual decrease in system heat exchange efficiency as water temperature rises during water circulation, and the easy adsorption of large amounts of dust, fibers, and other pollutants by the motor body, forming a heat insulation barrier that hinders heat conduction between the water cooling system and the motor surface, this invention provides a water-cooling mechanism for a fan motor.

A uniformly distributed aeration pipe is fixedly connected to the side of the conical shell away from the annular shell. A uniformly distributed aeration hole is opened on one side of the aeration pipe.

[0006] As a further improvement to this technical solution, the transmission mechanism includes a reciprocating lead screw. The reciprocating lead screw is disposed between the two mounting plates. Both ends of the reciprocating lead screw pass through the mounting plates and are movably connected to them. One end of the reciprocating lead screw is fixedly connected to a transmission shaft. One end of the transmission shaft passes through the annular shell and is fixedly connected to the output end of the motor body. A slip ring is installed on the side wall of the reciprocating lead screw. A circular plate is fixedly connected to the side wall of the slip ring. Transmission plates are symmetrically fixedly connected to the side of the circular plate opposite to the mounting plate. One side of the transmission plate passes through the mounting plate and is movably connected to it. The side of the transmission plate closest to the annular shell extends into the annular shell and is fixedly connected to the piston ring.

[0007] To achieve continuous cooling of the motor body 1, the cooling mechanism includes a housing. A housing is positioned above the annular plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this fan motor water cooling mechanism, through the cooperation between the body tube, the conical tube, the circulating pump, the cooling tube and the rectangular heat sink, the circulating pump circulates the water inside the cooling tube, the conical tube and the body tube, and the body tube contacts the motor body to play a heat exchange role, thereby achieving the cooling effect on the motor body. 2. In this water-cooling mechanism for a fan motor, the cooperation between the housing, circular plate, air bladder, air exchange shell, air nozzle, and one-way valve enables the reciprocating screw to drive the circular plate to move back and forth through the slip ring, which can repeatedly supply air to the housing. The air is then sprayed through the air nozzle onto the cooling pipe and rectangular heat sink, achieving the effect of cooling the rectangular heat sink and cooling pipe, effectively solving the problem of the gradual temperature rise after water circulation.

[0013] 3. In this water-cooling mechanism for a fan motor, the mutual cooperation between the reciprocating screw, circular plate, annular shell, transmission plate, conical shell, motor body, aeration pipe, and aeration holes enables the motor body to drive the reciprocating screw to rotate, which in turn causes the circular plate to drive the piston ring to move left and right, sending gas into the conical shell and finally into the aeration pipe and out through the aeration holes to form aeration. This can clean the dust accumulated on the motor body through aeration, and at the same time, it can cool the motor body and the casing pipe. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In some existing motor water cooling mechanisms, as the water temperature continues to rise during water circulation, the system's heat exchange efficiency gradually decreases. When the temperature difference between the water and the motor surface narrows, the heat dissipation effect is almost ineffective. Moreover, fans are often used in complex environments such as mines and tunnels, and the motor body easily adsorbs a large amount of dust, fibers, and other pollutants. The accumulated dust layer forms a heat insulation barrier, hindering the heat conduction between the water cooling system and the motor surface.

[0018] Therefore, the present invention provides a water-cooling mechanism for a fan motor. See below. Figures 1 to 10 As shown, it includes a motor body 1, a body tube 3 is provided on the side wall of the motor body 1, the body tube 3 is arranged in an arc structure with a wave-shaped bend around the motor body 1, and a uniformly distributed body heat sink 2 is fixedly connected to the side wall of the motor body 1, the body heat sink 2 is located between the body tube 3, a base plate 19 is fixedly connected to one side of the motor body 1 near the bottom, a support plate 5 is fixedly connected to the top of the base plate 19, an aeration component is fixedly connected to the top of the support plate 5, a conical tube 7 is installed on the aeration component, one end of the conical tube 7 is fixedly connected to one end of the body tube 3, an mounting plate 15 is fixedly connected to the top of the base plate 19, two mounting plates 15 are provided, a transmission mechanism is provided between the two mounting plates 15, the transmission mechanism is fixedly connected to the output end of the motor body 1, and the transmission component is fixedly connected to the aeration component; For details, see Figures 1 to 10 As shown, an annular plate 20 is provided above the mounting plate 15. Rectangular heat sinks 21 are evenly distributed within the annular plate 20. Both ends of the rectangular heat sinks 21 are fixedly connected to the inner wall of the annular plate 20. Cooling pipes 22 are installed between several rectangular heat sinks 21, with both ends of the cooling pipes 22 passing through the annular plate 20 and extending to the outside of the annular plate 20. A circulating pump 31 is installed on the top of the base plate 19. One end of the cooling pipe 22 is fixedly connected to the input end of the circulating pump 31, one end of the tapered pipe 7 is fixedly connected to the output end of the circulating pump 31, and the other end of the cooling pipe 22 is fixedly connected to one end of the body pipe 3. A cooling mechanism is provided above the annular plate 20, and the cooling mechanism includes a housing 2. 3. A housing 23 is provided above the annular plate 20. Several evenly distributed air nozzles 32 are fixedly connected to the bottom of the housing 23. The air nozzles 32 are connected to the interior of the housing 23. Connecting plates 24 are symmetrically fixedly connected between the housing 23 and one outer wall of the annular plate 20. A vertical plate 34 is fixedly connected to the bottom of the annular plate 20 near the annular shell 4. The bottom of the vertical plate 34 is fixedly connected to the top of the mounting plate 15. A fixing plate 25 is symmetrically fixedly connected to one side of one of the mounting plates 15. An inflation mechanism is provided between the two fixing plates 25. A square air pipe 30 is fixedly connected between the inflation mechanism and one side of the housing 23. The square air pipe 30 is connected to the interior of the housing 23. During operation, the circulation pump 31 is first started, which circulates the coolant in the body tube 3, the conical tube 7, and the cooling tube 22. The circulation pump 31 is a common liquid circulation pump, and its usage and working principle are common knowledge among those in the field, so it will not be described in detail in this technical solution. When the motor body 1 is working, it will generate heat, which can be directly cooled by the body tube 3 and the body heat sink 2. The body tube 3, the conical tube 7, and the cooling tube 22 in this technical solution are all made of copper, which has an effective thermal conductivity and is more effective in heat exchange with the motor body 1.

[0019] For details, see Figures 5 to 8 As shown, the aeration mechanism includes an annular shell 4. The annular shell 4 is fixedly connected to the top of the support plate 5. The side of the annular shell 4 away from the motor body 1 is not closed. A conical shell 6 is fixedly connected to one side of the annular shell 4. The conical shell 6 is cut off. The side of the conical shell 6 opposite to the annular shell 4 is not closed. An arc-shaped opening 13 is opened on one side of the annular shell 4. The annular shell 4 and the conical shell 6 are internally connected. A piston ring 11 is provided inside the annular shell 4. One side of the piston ring 11 is fixedly connected to the transmission assembly. A conical tube 7 is sleeved on the outer wall of the conical shell 6. A uniformly distributed aeration pipe 8 is fixedly connected to the side of the conical shell 6 away from the annular shell 4. A uniformly distributed aeration hole 9 is opened on one side of the aeration pipe 8.

[0020] The transmission mechanism includes a reciprocating lead screw 16, which is disposed between two mounting plates 15. Both ends of the reciprocating lead screw 16 pass through the mounting plates 15 and are movably connected to them. One end of the reciprocating lead screw 16 is fixedly connected to a drive shaft 14, and one end of the drive shaft 14 passes through the annular shell 4 and is fixedly connected to the output end of the motor body 1. A slip ring 17 is installed on the side wall of the reciprocating lead screw 16, and a circular plate 18 is fixedly connected to the side wall of the slip ring 17. A transmission plate 12 is symmetrically fixedly connected to the side of the circular plate 18 opposite to the mounting plate 15. One side of the transmission plate 12 passes through the mounting plate 15 and is movably connected to it. The side of the transmission plate 12 closest to the annular shell 4 extends into the annular shell 4 and is fixedly connected to the piston ring 11.

[0021] During operation, lubricating oil or other lubricants can be applied to the inside of the annular shell 4 beforehand. This reduces friction between the piston ring 11 and the inner wall of the annular shell 4, and improves sealing. Lubrication can also extend the service life of the annular shell 4 and the piston ring 11. Since the conical tube 7 is wound around the conical shell 6, it can cool the conical shell 6 as a whole. After cooling, the conical shell 6 also cools the air inside it. When the motor body 1 is working, the reciprocating screw 16 drives the circular plate 18 to slide back and forth, causing the piston ring 11 to move back and forth. This pushes the air inside the annular shell 4 and the conical shell 6 through the aeration hole 9 to be discharged. This cooled air will directly act on the motor body 1, the heat sink 2, and the tube 3. The cooled air can further cool the motor body 1, effectively improving the cooling efficiency.

[0022] For details, see Figure 1 and Figure 7 As shown, the inflation mechanism includes an airbag 27, which is disposed between two fixed plates 25. An air exchange shell 26 is fixedly connected to one side of the airbag 27, and the airbag 27 and the air exchange shell 26 are internally connected. The bottom of the square air tube 30 is fixedly connected to the outer wall of the air exchange shell 26, and the air exchange shell 26 is internally connected to the square air tube 30. A one-way air valve 29 is installed on the side of the air exchange shell 26 that is away from the airbag 27. A push-pull plate 28 is fixedly connected between the two transmission plates 12 and the side opposite to the airbag 27, and the push-pull plate 28 is fixedly connected to one side of the airbag 27.

[0023] During operation, the output shaft of the motor body 1 drives the reciprocating screw 16 to rotate. When the reciprocating screw 16 rotates, the slip ring 17 and the circular plate 18 reciprocate left and right, causing the push-pull plate 28 to follow the circular plate 18 in reciprocating left and right movements. This achieves the reciprocating compression and stretching of the airbag 27. Through the repeated compression and stretching of the airbag 27, air blowing and air intake operations can be performed. This can repeatedly provide gas to the housing 23, achieving the effect of jetting gas to the rectangular heat sink 21 and cooling pipe 22, thereby accelerating the cooling of the rectangular heat sink 21 and cooling pipe 22. This can effectively prevent the temperature difference between the coolant and the motor body 1 from gradually decreasing, and the continuous cooling of the motor body 1 can be achieved through the circulation of the coolant.

[0024] Further, see Figure 1 As shown, several aeration pipes 8 are fixedly connected to the side walls with evenly distributed heat sinks 10. Both the aeration pipes 8 and the heat sinks 10 are made of copper. The heat sinks 10 can improve the cooling effect of the aeration pipes 8. Copper has a high thermal conductivity, second only to silver among common metals. Copper also has good ductility and plasticity, making it easy to process heat dissipation components of various shapes and allowing them to be directly attached to the heat source.

[0025] Further, see Figure 1 As shown, several uniformly distributed heat sinks 33 are fixedly connected to the inner wall of the outer side of the conical shell 6. The heat sinks 33 are arranged in a ring array. Both the heat sinks 33 and the conical shell 6 are made of aluminum. Aluminum has good ductility and plasticity. Aluminum is easy to process into heat dissipation components of various shapes and sizes. Aluminum can quickly absorb and conduct heat, thereby effectively transferring heat from the heat source to the surrounding environment. This can quickly cool the air inside the conical shell 6.

[0026] Further, see Figure 1 and Figure 7 As shown, the airbag 27 is made of neoprene rubber and has a wavy design. This material has good physical and mechanical properties, high tensile strength and elongation, reversible crystallinity, good adhesion, self-extinguishing properties, is not easy to burn, and has high safety.

[0027] In summary, this effectively solves the existing technical problems.

[0028] Working Principle: This technical solution requires the power of the motor body 1 itself for operation. Coolant is pre-filled in the cooling pipe 22, conical pipe 7, and body pipe 3. A circulation pump 31 between the cooling pipe 22 and conical pipe 7 circulates the coolant. When the motor body 1 is used, its output shaft drives the reciprocating screw 16 via the transmission shaft 14, causing the slip ring 17 and circular plate 18 to reciprocate left and right. When the circular plate 18 moves to the right, it drives the transmission plate 12 to push the piston ring 11 to the right, allowing the space inside the annular shell 4 to enter the conical shell 6. Air inside the conical shell 6 then enters the aeration pipe 8 and is finally discharged through the aeration hole 9, forming aeration. Aeration removes dust from the motor body 1 and cools the motor body 1, the body tube 3, and the heat sink 2. When the circular plate 18 moves to the left, it drives the piston ring 11 to move to the left through the transmission plate 12. This draws outside air into the aeration pipe 8 and the conical shell 6 through the aeration hole 9, and finally into the annular shell 4. At this time, the circulating pump 31 circulates the coolant and cools the conical shell 6 through the conical pipe 7. Simultaneously, the conical shell 6 cools the air inside. After cooling, the air is discharged again after aeration, which effectively improves the cooling effect on the motor body 1 and the body tube 3 on the motor body 1. This process can prevent dust from accumulating on the motor body 1.

[0029] When the reciprocating screw 16 drives the slip ring 17 and the circular plate 18 to slide back and forth, it drives the push-pull plate 28 through the transmission plate 12 to stretch and compress the airbag 27. When the push-pull plate 28 compresses the airbag 27, the one-way air valve 29 closes, and the air in the airbag 27 enters the housing 23 through the air exchange shell 26 and the square air pipe 30. Simultaneously, the air in the housing 23 is discharged through the jet nozzle 32. In addition, the jet nozzle 32 can increase the pressure of the gas ejection. The larger pressure is sprayed onto the rectangular heat sink 21 and the cooling pipe 22. On the one hand, it can cool the rectangular heat sink 21 and the cooling pipe 22. On the other hand, it can clean the dust on the rectangular heat sink 21 and the cooling pipe 22, preventing dust from accumulating on the cooling pipe 22 and reducing the cooling effect. When the push-pull plate When the airbag 27 is stretched, it will suck in air. At this time, the one-way valve 29 opens, and air enters the airbag 27 through the one-way valve 29. Another part of the air in the shell 23 and the square air tube 30 will flow back into the airbag 27. This process can continuously cool the cooling tube 22 and the rectangular heat sink 21. The cooled cooling tube 22 can exchange heat with the coolant, thus continuously cooling the coolant. Driven by the circulation pump 31, the coolant is circulated, which simultaneously cools the motor body 1 and the conical shell 6. This can simultaneously cool the motor body 1 and the air. Then, the cooled air is sprayed onto the motor body 1 and the body tube 3 through aeration, which effectively further cools the motor body 1, thereby improving the cooling efficiency.
