Description
Technical Field
[0001] The invention relates to the technical field of motor cooling, and in particular to a disc-type motor cooling device capable of cooling both inside and outside the motor. Background Art
[0002] A motor is a device that converts electrical energy into mechanical energy. Its main components include: Stator: The stator is the stationary part of the motor, including the stator core and stator winding. The stator core is usually composed of laminated silicon steel sheets to reduce energy loss. The stator winding is the part that generates a magnetic field through current; Rotor: The rotor is the rotating part of the motor and is located inside the stator. The rotor also has a core and windings, or a short-circuit ring made of conductive material. The rotor generates a magnetic field under the action of current and rotates under the action of the stator magnetic field; Brushes and commutator: Brushes are used to transfer current to the rotor winding, while the commutator is used to change the direction of current to ensure that the rotor continues to rotate; Shaft: The shaft is the main output component of the motor. The rotor is connected to the mechanical load through the shaft to transfer the mechanical energy generated by the rotor to the load; Casing: The casing is the external structure of the motor, protecting the internal components from the external environment and providing mechanical support.
[0003] Since the high-speed rotation of the rotor during the operation of the motor will generate a large amount of heat, in order to improve the operating efficiency of the motor and reduce the heat load during the operation of the motor, the motor needs to be heat-dissipated. For example, the announcement number CN108494147B discloses a heat-dissipating motor, which includes a motor shaft, a stator, a rotor, a housing and a base, and also includes a spiral tube, an air guide plate and a compression module; the compression module includes a cam, a telescopic cylinder, an air pipe, a drying chamber and a one-way valve; the spiral tube is rotatably arranged on the outer ring of the housing; the spiral tube is configured as a variable diameter pipe, and the diameter of the bottom of the housing is 2-3 times the diameter of the top; an axial through hole connected to the spiral tube is provided on the top of the housing, and the through hole is connected to the air guide plate; the air guide plate is installed at one end inside the housing; air is added along the spiral tube to cool the motor, and the air guide plate is used to input dry air into the motor to cool the inside of the motor.
[0004] When the heat dissipation motor is in operation, the water vapor in the air is liquefied to cool the motor, and the air is blown into the motor after it is fully dried, thereby improving the heat dissipation efficiency, preventing water vapor from entering the motor, and increasing the life of the motor. It is essentially air-cooled heat dissipation, which has certain limitations when used, and the air-cooled heat dissipation efficiency is low.
[0005] Therefore, a novel disc-type motor cooling device with both internal and external cooling can be adopted to solve the shortcomings of the prior art. Summary of the invention

[0024] 3: This disc-type motor cooling device with both internal and external cooling can ensure the stability of the pressure in the closed space between the stator and the rotor in the motor by setting a ventilation pipe.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0048] Example 1: Reference Figure 1-Figure 7 A disk-type motor cooling device with both internal and external cooling comprises a housing 1, a bracket 15 fixedly mounted inside the housing 1, and a mounting ring 10 fixedly mounted outside the housing 1;

[0050] A plurality of bearings are fixedly mounted on the docking ring 14, and the inner ring of the docking ring 14 is fixedly connected to the outer ring of the bearing, and the inner ring of the bearing is fixedly connected to the bracket 3 15 through a rod; the function of the bearing is to reduce friction, so that the rotor 12 rotates more smoothly and improves the operating efficiency of the motor;
[0051] The specific operation mode and operation principle between the wire 2, the rotating shaft 3, the stator 13 and the rotor 12 will not be elaborated here because it is an existing mature technology, which is the working principle of the motor.
[0052] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 5, Figure 8-Figure 17 , the internal heat dissipation part includes a sealing plate 1 7 and a sealing plate 2 8 fixedly mounted on both sides of the annular patch 5, a sealing mechanism is installed between the sealing plate 1 7 and the sealing plate 2 8 and the bracket 2 11, a water tank 1 23 is fixedly mounted on the bracket 3 15, and a water pump 1 is fixedly mounted in the water tank 1 23, a water spraying mechanism and an air suction mechanism are installed between the water tank 1 23 and the sealing plate 2 8, and a pressure control mechanism is installed on the sealing plate 1 7.
[0053] The sealing mechanism includes a sealing component 16 and a sealing component 2 17 fixedly mounted on the sealing plate 1 7 and the sealing plate 2 8. The sealing component 1 16 is fixedly connected to the annular patch 5, and the sealing component 2 17 is mechanically rotatedly connected to the bracket 2 11.
[0054] The sealing component 1 16 and the sealing component 2 17 are existing mechanical sealing structures. The mechanical sealing structure is a structure used to prevent liquid or gas leakage and is widely used in various mechanical equipment, such as pumps, compressors, agitators, etc.
[0055] The main function of a mechanical seal is to prevent the working medium from leaking from the sealing end and to prevent external contaminants from entering the interior of the equipment, which is not shown in the figure. Its basic composition and working principle are as follows:
[0056] Main components:
[0057] Static ring (static sealing ring): usually fixed on the static parts of the equipment, such as the pump housing; the contact surface of the static ring contacts the dynamic ring to form a sealing surface, which is usually made of hard materials (such as tungsten carbide, ceramic) to ensure wear resistance and high temperature resistance.
[0058] Dynamic ring (dynamic sealing ring): fixed on the rotating part, such as the pump shaft; forms a sealing surface with the contact surface of the static ring; usually combined with a spring to ensure that the sealing surface remains in contact during operation.
[0059] Spring: responsible for maintaining the sealing pressure between the dynamic ring and the static ring; the spring design can be a spiral spring, corrugated spring, etc. to meet different application requirements.
[0060] Seal Spring Seat: Fixes and supports the position of the spring, ensuring that the spring applies pressure in the proper position.
[0061] The mating surface of the sealing ring is the contact surface between the dynamic ring and the static ring. The sealing performance directly affects the sealing effect of the equipment. Generally, high finish and accurate manufacturing tolerance are required.
[0062] Auxiliary seals (such as O-rings or V-rings): Mainly used to fill the tiny gap between the dynamic ring and the static ring to further improve the sealing effect; usually made of elastic materials (such as rubber or polyurethane).
[0063] Working principle:
[0064] Sealing surface contact: The dynamic ring and the static ring are kept in contact by the pressure applied by the spring, thus forming a sealing surface; the contact between the sealing surfaces can effectively prevent the leakage of liquid or gas.
[0065] Pressure balance: In many applications, mechanical seals need to handle internal and external pressure differences; some mechanical seals are designed with liquid or gas balancing devices to help balance the pressure and reduce the burden on the sealing surface.
[0066] Temperature and friction: Due to friction and the working environment, the sealing surface will generate heat. Cooling and lubrication need to be considered during design to prevent the sealing surface from overheating.
[0067] The purpose of designing the sealed state here is to prevent the leakage of atomized water and cause insulation short circuit, thereby improving the stability and safety of the motor operation.
[0068] The water spray mechanism includes an annular water pipe 1 28 fixedly mounted on the bracket 3 15, the annular water pipe 1 28 is fixedly connected to a plurality of water guide pipes 2 24, each water guide pipe 24 is fixedly connected to an atomizing nozzle 26, a plurality of water outlet holes corresponding to the atomizing nozzle 26 are opened on the sealing plate 28, and the water pump 1 is fixedly connected to the annular water pipe 1 28 through a water outlet pipe 32;
[0069] The water pump in the water tank 23 will transport the cold water in the water tank 23 to the annular water pipe 28 through the water outlet pipe 32, and then transport the cold water to multiple water pipes 24 through the annular water pipe 28, and then the water pipes 24 will transport the cold water to the atomizing nozzle 26, and the atomizing nozzle 26 will spray the cold water into between the motor rotor 12 and the stator 13 through the water outlet hole. Once the stator 13 and the rotor 12 encounter the atomized cold water, the atomized cold water will be evaporated and gasified to form water vapor through the heat generated, so as to directly perform water cooling on the stator 13 and the rotor 12 inside the motor, and the heat dissipation efficiency is greatly improved.
[0070] The air suction mechanism includes an air pump 27 fixedly mounted on the bracket 3 15, the air inlet of the air pump 27 is fixedly connected to the air inlet pipe 33, the bracket 3 15 is fixedly mounted with an annular water pipe 29, the annular water pipe 29 is fixedly connected to multiple air suction pipes 25, the sealing plate 2 8 is provided with multiple air outlet holes matching the corresponding air suction pipes 25, and a liquefaction structure is installed between the air outlet of the air pump 27 and the water tank 1 23;
[0071] As the cold water between the stator 13 and the rotor 12 in the motor forms water vapor, the air pump 27 will suck the water vapor between the stator 13 and the rotor 12 into the annular water pipe 29 through the intake pipe 25, and then suck the water vapor in the annular water pipe 29 into the air pump 27 through the intake pipe 33, and then introduce the water vapor into the water tank 1 23 through the outlet pipe 36 for cooling.
[0072] The liquefaction structure includes an air disk 35 fixedly installed at the bottom of the water tank 23. The air outlet of the air pump 27 is connected to the air disk 35 through an air outlet pipe 36. A plurality of exhaust holes are opened on the top of the water tank 23, and a gas molecule membrane 34 is fixedly installed in each exhaust hole.
[0073] Before the water vapor enters the water tank 23, the water vapor will be dispersed through the air disk 35, so that the water vapor can evenly pass through the water in the water tank 23 from bottom to top, which can not only increase the flow rate of the water vapor, but also increase the contact area between the water vapor and the cold water in the water tank 23, and improve the efficiency of the water vapor liquefaction, thereby achieving the purpose of improving the cooling and heat dissipation efficiency; the role of the exhaust hole is to keep the air pressure in the water tank 23 constant, and the gas molecular membrane 34 is an existing technology that can only pass gas molecules but not liquid molecules, so as to avoid the loss of liquefied water vapor.
[0074] The pressure control mechanism includes a plurality of air holes opened on the sealing plate 7, each of which is fixedly installed with a vent pipe 18, each of which is fixedly installed with a dustproof net, and each of which is fixedly installed with a blocking ring 19, and each of which is installed with a sealing structure matched with the blocking ring 19;
[0075] As the air pump 27 sucks out the gas between the stator 13 and the rotor 12, the gas between the stator 13 and the rotor 12 decreases, which will produce a negative pressure effect. At this time, gas will be added to the space between the stator 13 and the rotor 12 inside the motor through the ventilation pipe 18 for filling pressure, thereby keeping the internal pressure of the motor stable, which is beneficial to the stability of the motor operation.
[0076] The sealing structure includes a plurality of support plates 21 fixedly mounted on the blocking ring 19, a telescopic rod 22 is fixedly mounted on each support plate 21, a column spring 39 is fixedly mounted between the telescopic section of each telescopic rod 22 and the corresponding support plate 21, and a blocking plate 20 matching the blocking ring 19 is fixedly mounted on the telescopic ends of the plurality of telescopic rods 22;
[0077] As the internal pressure of the motor decreases, the sealing plate 20 will move to the side away from the sealing ring 19, so that the sealing plate 20 is separated from the sealing ring 19. At this time, the gas will enter the inside of the motor through the gap between the sealing ring 19 and the sealing plate 20 (the inside of the motor refers to the enclosed space surrounded by sealing plate 1 7, sealing plate 2 8, rotor 12 and annular patch 5, and the outside of the motor refers to the space outside the enclosed space but inside the casing 1); the function of the dustproof net is to block external dust and reduce the probability of dust adhesion affecting the operation of the rotor 12.
[0078] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 1-Figure 5 , Figure 15-16 , Figure 18-19 , external heat dissipation part, the external heat dissipation part includes a heat dissipation fan 4 fixedly mounted on the mounting ring 10, a water tank 2 37 fixedly mounted on the water tank 1 23, a plurality of water guide pipes 1 9 in contact with the housing 1 are mounted on the water tank 2 37 through a water guide mechanism, the water tank 2 37 is connected to the water tank 1 23 through a plurality of heat conducting rods 31, a water pump 2 is fixedly mounted in the water tank 2 37, and a heat conducting mechanism is installed between the water tank 2 37 and the heat dissipation fan 4. The water in the water tank 1 23 and the water tank 2 37 is aviation cooling water, which not only has a high cooling performance, but also has the advantage of reducing rust on components.
[0079] The water guide mechanism includes an inlet pipe group 38 fixedly connected to the water guide pipe 1 9, a water inlet pipe 30 fixedly connected to the water inlet pipe group 38, the water inlet pipe 30 is connected to the water tank 2 37, and the end of the water guide pipe 1 9 away from the inlet pipe group 38 is fixedly connected to the outlet pipe group, and the outlet pipe group is connected to the water outlet of the water pump 2 through the outlet pipe;
[0080] Water pump 2 transports the cold water in water tank 2 37 to the water outlet pipe group through the water outlet pipe, and then transports the cold water to multiple water pipes 1 9 through the water outlet pipe group. The temperature of the water in each water pipe 9 is the same, forming a multi-loop heat dissipation water path with a more efficient heat dissipation effect. A storage groove that matches the water pipe 1 9 is provided on the outer shell 1, which can increase the contact area between the water pipe 1 9 and the outer shell 1, thereby improving the heat conduction efficiency. The cold water in the water pipe 1 9 will carry the heat on the outer shell 1, and then enter the water inlet pipe 30 through the water inlet pipe group 38, and then enter the water tank 2 37 through the water inlet pipe 30. Since the temperature of the outer shell 1 is lower than the temperature inside the above-mentioned motor, the temperature of the water in water tank 2 37 is lower than the temperature of the water in water tank 1 23. At this time, the heat in water tank 1 23 will be conducted to the water in water tank 2 37 through the heat conducting rod 31, thereby accelerating the dissipation of heat in the water in water tank 1 23.
[0081] The heat conduction mechanism includes a plurality of heat conducting sheets 40 fixedly mounted on the water tank 37, each heat conducting sheet 40 penetrates the top of the water tank 37 and extends out of the water tank 37, a plurality of heat dissipating fins are fixedly mounted on the heat dissipating fan 4, and each heat conducting sheet 40 contacts with the heat dissipating fins on the heat dissipating fan 4;
[0082] The heat conducting sheet 40 absorbs the heat in the water in the water tank 2 37, and then conducts it to the heat dissipating fins, and then the heat on the heat dissipating fins is dissipated through the heat dissipating fan 4. The heat conducting sheet 40 adopts an arc-shaped design, which divides the water tank 2 37 into multiple channels, reducing the flow rate of water in a single channel, which can effectively improve the heat dissipation efficiency of the water, and at the same time increase the contact area between the water and the heat conducting sheet 40, thereby further improving the heat dissipation efficiency.
[0083] The specific operation steps of this device are as follows:
[0084] When the motor is running, the water pump 1 in the water tank 1 23 will transport the cold water in the water tank 1 23 to the annular water pipe 1 28 through the water outlet pipe 32, and then transport the cold water to the multiple water pipes 2 24 through the annular water pipe 1 28, and then the water pipes 2 24 will transport the cold water to the atomizing nozzle 26, and the atomizing nozzle 26 will spray the cold water into the space between the motor rotor 12 and the stator 13 through the water outlet hole. Once the stator 13 and the rotor 12 encounter the atomized cold water, the atomized cold water will be evaporated and gasified to form water vapor through the heat generated;
[0085] After the cold water between the stator 13 and the rotor 12 in the motor forms water vapor, the air pump 27 will suck the water vapor between the stator 13 and the rotor 12 into the annular water pipe 29 through the suction pipe 25, and then suck the water vapor in the annular water pipe 29 into the air pump 27 through the air inlet pipe 33, and then introduce the water vapor into the water tank 23 for cooling through the air outlet pipe 36 (before the water vapor enters the water tank 23, the water vapor will be dispersed through the air disk 35, so that the water vapor passes through the water in the water tank 23 evenly from bottom to top, which can not only increase the flow rate of the water vapor, but also increase the contact area between the water vapor and the cold water in the water tank 23, and improve the efficiency of the water vapor liquefaction, so as to achieve the purpose of improving the cooling and heat dissipation efficiency; the function of the exhaust hole is to keep the air pressure in the water tank 23 constant, and the gas molecular membrane 34 is an existing technology, which can only pass gas molecules but not liquid molecules, so as to avoid the loss of liquefied water vapor).
[0086] As the air pump 27 sucks out the gas between the stator 13 and the rotor 12, the gas between the stator 13 and the rotor 12 decreases, which will produce a negative pressure effect. At this time, gas will be added to the space between the stator 13 and the rotor 12 inside the motor through the ventilation pipe 18 for filling pressure, thereby keeping the internal pressure of the motor stable, which is beneficial to the stability of the motor operation.
[0087] The water pump 2 delivers the cold water in the water tank 2 37 to the water outlet pipe group through the water outlet pipe, and then delivers the cold water to the multiple water pipes 9 through the water outlet pipe group. The water temperature in each water pipe 9 is the same, forming a multi-circuit heat dissipation water path with a more efficient heat dissipation effect. The housing 1 is provided with a storage groove that matches the water pipe 9, which can increase the contact area between the water pipe 9 and the housing 1, thereby improving the heat conduction efficiency. The cold water in the water pipe 9 will carry the heat on the housing 1, and then enter through the water inlet pipe group 38. The water enters the water inlet pipe 30, and then enters the water tank 2 37 through the water inlet pipe 30. Since the temperature of the outer shell 1 is lower than the temperature inside the above-mentioned motor, the temperature of the water in the water tank 2 37 is lower than the temperature of the water in the water tank 1 23. At this time, the heat in the water tank 1 23 will be transferred to the water in the water tank 2 37 through the heat conducting rod 31, thereby accelerating the dissipation of heat in the water in the water tank 1 23; the heat conducting sheet 40 will absorb the heat in the water in the water tank 2 37, and then transfer it to the heat dissipation fins, and then the heat on the heat dissipation fins will be dissipated through the heat dissipation fan 4.
