Description

Technical Field

[0001] This invention relates to the field of induction motor technology, specifically to an induction motor that facilitates heat dissipation. Background Technology

[0002] The working principle and heat source of induction motors: Induction motors (especially three-phase squirrel-cage motors) operate based on the principle of electromagnetic induction. Alternating current is applied to the stator windings, generating a rotating magnetic field. This magnetic field cuts the rotor bars (usually aluminum or copper), inducing a current in the rotor. The interaction between the induced current and the rotating magnetic field produces electromagnetic torque, driving the rotor to rotate. The main heat source is the resistive loss generated when the current flows through the stator windings (copper wire) and rotor bars (aluminum or copper). This is one of the most significant heat sources, especially during startup or overload. Other losses include hysteresis and eddy current losses caused by the alternating magnetic field in the stator and rotor cores, bearing friction, wind resistance (fan or rotor rotation agitating air), and other losses caused by leakage magnetic fields. High temperature is the primary factor contributing to the aging of insulation materials (such as the enamel film of enameled wire, slot insulation, and phase-to-phase insulation), leading to decreased insulation performance, shortened motor life, and increased winding resistance with rising temperature, further increasing copper losses, creating a vicious cycle and reducing efficiency. To protect insulation, there are strict standards for temperature rise limits (the difference between the motor operating temperature and the ambient temperature). Poor heat dissipation means that a motor of the same size cannot output higher power, and overheating is one of the main causes of motor failures (such as winding short circuits and bearing damage).

[0003] Traditional low-speed motors mostly use surface natural cooling, relying on natural convection and radiation between the motor casing and the surrounding air to dissipate heat. This method has the simplest structure and the lowest cost, but its heat dissipation capacity is very limited, and most of the heat dissipation methods are from the outside, which cannot remove heat from the heat source in a timely manner. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an induction motor that facilitates heat dissipation, comprising a motor base, a motor housing connected to the top of the motor base, a heat dissipation device fixedly connected to the side of the motor housing, and a drive device fixedly connected to the inner wall of the motor housing.

[0005] The heat dissipation device includes a heat dissipation shell, a heat dissipation component fixedly connected to the inner wall of the heat dissipation shell, a flow guiding component fixedly connected to the inner wall of the heat dissipation component, and a fan assembly fixedly connected to the side of the motor base located on one side of the flow guiding component. The heat dissipation shell provides overall support, the heat dissipation component guides the flow of cooling oil, the flow guiding component facilitates the flow of internal cooling oil, thereby increasing the circulation speed of the cooling oil, and the fan assembly provides active air cooling to the gaps between the heat dissipation components, thereby improving the passive heat dissipation efficiency of the heat dissipation components.

[0006] Preferably, the heat dissipation assembly includes a flow guide baffle, a connecting plate is fixedly connected to the side of the flow guide baffle, a heat dissipation pipe is fixedly connected to the side of the connecting plate, an inlet is provided at the end of the side of the heat dissipation pipe near the flow guide baffle, an outlet is provided at the end of the heat dissipation pipe away from the heat dissipation pipe, the side of the heat dissipation pipe is fixedly connected to the inner wall of the motor base, and the side of the heat dissipation pipe away from the motor base is fixedly connected to the side of the flow guide assembly.

[0007] Preferably, the flow guiding assembly includes an oil guide pipe, a diffuser baffle is fixedly connected to the inner wall of the oil guide pipe, an oil outlet is opened on the side of the oil guide pipe located on the side of the diffuser baffle, a spiral blade is fixedly connected to the top of the diffuser baffle, an oil supply pipe is sleeved and rotatably connected to the side of the spiral blade, an oil inlet is opened on the side of the oil supply pipe that matches the inlet, the side of the oil guide pipe communicates with the side of the driving device, and the side of the oil supply pipe is fixedly connected to the side of the heat dissipation pipe.

[0008] Preferably, the fan assembly includes a fixed baffle, an air inlet on the side of the fixed baffle, a fan shaft rotatably connected to the side of the fixed baffle via a bracket, straight fan blades fixedly connected to the side of the fan shaft, and curved fan blades fixedly connected to the side of the straight fan blades located on the side of the air inlet. The end of the fan shaft away from the fixed baffle passes through the side of the motor base and is fixedly connected to the side of the oil guide pipe. The side of the fixed baffle is fixedly connected to the side of the motor base. When the motor rotates, the corresponding component of the drive device drives the oil guide pipe to rotate, and the corresponding component of the drive device drives the cooling oil to flow. After entering the oil guide pipe, the cooling oil flows along the inner wall of the oil guide pipe. The rotation of the oil guide pipe drives the diffuser baffle to rotate, and the cooling oil is released along the oil outlet through the guiding action of the diffuser baffle. Under the driving action of the diffuser baffle, the fan shaft rotates... The rotating helical blades drive the cooling oil to flow, causing it to flow from the end near the drive unit to the end near the oil inlet. The cooling oil flows out through the side of the oil inlet and enters the interior of the heat dissipation pipe through the inlet. The cooling oil then flows out through the heat dissipation pipe to the outlet. During the flow of the cooling oil, the guide pipe drives the fan shaft to rotate, which in turn drives the straight and curved fan blades to rotate. The rotation of the curved fan blades causes air to pass through the air inlet and enter the side of the straight fan blades. The straight fan blades then guide the air through the guide to flow into the gaps of the heat dissipation pipe, thereby carrying away the heat inside the heat dissipation pipe and reducing the temperature of the cooling oil. This active cooling is achieved by reducing the volume of air intake required by the air inlet design, which facilitates heat dissipation of the motor in confined working environments.

[0009] Preferably, the driving device includes a drive shaft, a sealing ring is sleeved and rotatably connected to the side of the drive shaft, a drive assembly is fixedly connected to one end of the drive shaft, a stator assembly is sleeved and rotatably connected to the side of the drive assembly, a guide groove adapted to the outlet is opened on the side of the stator assembly, the side of the stator assembly is fixedly connected to the inner wall of the motor base, and the sealing ring passes through the side of the motor base and is fixedly connected to the side of the motor base.

[0010] Preferably, the drive assembly includes a hollow rotating shaft, a spiral bracket fixedly connected to the side of the hollow rotating shaft, a cable support fixedly connected to the end of the spiral bracket away from the hollow rotating shaft, a guide assembly fixedly connected to the portion of the hollow rotating shaft between the spiral brackets, the cable support contacting the inner wall of the stator assembly, a side of the hollow rotating shaft fixedly connected to the side of the drive shaft, and the end of the hollow rotating shaft away from the drive shaft communicating with the side of the oil guide pipe. The cable support and the stator assembly rotate via an inductor. During the rotation of the cable support, the cable support rotates, causing the spiral bracket to rotate, which in turn rotates the hollow rotating shaft, which in turn rotates the guide assembly, and simultaneously drives the spiral bracket to rotate. The cooling oil flows smoothly, facilitating its movement during motor operation and improving cooling efficiency. Guided by the flow channel, the oil returns to the other side of the spiral support, achieving internal circulation and cooling. This circulation also lubricates the cable support and stator assembly, ensuring smooth motor operation. A sealing ring prevents oil leakage. The cooling oil, in conjunction with the flow channel on the side of the spiral support, circulates from the outside in. After passing through the guide assembly, the oil re-enters the hollow shaft and is transferred to the oil pipe for further cooling. This process carries away more heat than simply flowing horizontally across the side of the spiral support, facilitating internal heat dissipation for the motor.

[0011] Preferably, the guiding component includes a triangular tube with an oil inlet on its side and guide vanes fixedly connected to the side of the triangular tube. The bottom of the triangular tube is connected to the side of the hollow rotating shaft. The triangular tube is positioned on one side of the spiral support. When the hollow rotating shaft rotates, the rotation of the hollow rotating shaft drives the triangular tube to rotate. The rotation of the triangular tube guides the cooling oil through the oil inlet, thereby driving the cooling oil to flow through the oil inlet into the interior of the hollow rotating shaft, thus driving the cooling oil to be guided along the hollow rotating shaft. When the motor rotates in the opposite direction, the prismatic design of the triangular tube increases the agitation of the cooling oil, thereby driving the cooling oil to be agitated between the spiral supports, thus facilitating the removal of impurities between the spiral supports, and facilitating the agitation of multiple cooling oil layers through the guide vanes, thereby facilitating the recycling of the cooling oil.

[0012] This invention provides an induction motor that facilitates heat dissipation. It has the following beneficial effects:

[0013] 1. The induction motor that facilitates heat dissipation is equipped with a heat dissipation shell, which provides overall support. The heat dissipation component guides the flow of cooling oil, and the flow guiding component facilitates the flow of internal cooling oil, thereby increasing the circulation speed of the cooling oil. The fan component provides active air cooling to the gaps between the heat dissipation components, thereby improving the passive heat dissipation efficiency of the heat dissipation components.

[0014] 2. This heat-dissipating induction motor is equipped with an oil guide pipe. When the motor rotates, the corresponding component of the drive unit drives the oil guide pipe to rotate, and the corresponding component of the drive unit drives the cooling oil to flow. After entering the oil guide pipe, the cooling oil flows along the inner wall of the oil guide pipe. The rotation of the oil guide pipe drives the diffuser baffle to rotate, and the cooling oil is released along the oil outlet through the guiding action of the diffuser baffle. Under the driving action of the diffuser baffle, the spiral blades rotate, and the rotation of the spiral blades drives the cooling oil to flow, so that the cooling oil flows from the end near the drive unit to the end near the oil inlet. The cooling oil flows out through the side of the oil inlet and along... The cooling oil enters the heat sink through the inlet and flows out through the outlet. During the flow of the cooling oil, the guide pipe drives the fan shaft to rotate. The rotation of the fan shaft drives the straight fan blades and the curved fan blades to rotate. The rotation of the curved fan blades drives the air through the air inlet and into the side of the straight fan blades. The straight fan blades drive the air through the guide and into the gap of the heat sink to flow. In this way, the air carries away the heat inside the heat sink, thereby reducing the temperature of the cooling oil and thus achieving active cooling. The design of the air inlet reduces the volume required to draw in air, making it easier to dissipate heat from the motor in a narrow working environment.

[0015] 3. This heat-dissipating induction motor is equipped with a cable support base. The cable support base and the stator assembly rotate via an inductor. During the rotation of the cable support base, the spiral bracket rotates, which in turn rotates the hollow shaft. The hollow shaft rotates, which in turn rotates the guide assembly. Simultaneously, the rotation of the spiral bracket causes the cooling oil to flow, thus improving cooling efficiency during motor operation. The cooling oil, guided by the guide groove, returns to the other side of the spiral bracket, achieving internal cooling oil circulation. This circulating cooling oil also lubricates the cable support base and stator assembly, ensuring stable motor operation. A sealing ring prevents cooling oil leakage. The cooling oil, in conjunction with the guide groove on the side of the spiral bracket, creates an inward-to-outward circulation process. The cooling oil, after passing through the guide assembly, re-enters the hollow shaft and is transferred to the oil guide pipe for further cooling. This method carries away more heat than simply flowing horizontally across the side of the spiral bracket, facilitating internal heat dissipation for the motor.

[0016] 4. This heat-dissipating induction motor is equipped with a triangular tube. When the hollow shaft rotates, the rotation of the hollow shaft drives the triangular tube to rotate. The rotation of the triangular tube guides the cooling oil through the oil inlet, thereby causing the cooling oil to flow into the interior of the hollow shaft. This guides the cooling oil along the hollow shaft. When the motor rotates in the opposite direction, the prismatic design of the triangular tube increases the agitation of the cooling oil, thereby causing the cooling oil to be agitated between the spiral supports. This facilitates the removal of impurities between the spiral supports, and the agitation of multiple cooling oil layers through the guide vanes facilitates the recycling of the cooling oil.

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-2 The present invention provides a technical solution: an induction motor that facilitates heat dissipation, including a motor base 1, a motor housing 2 connected to the top of the motor base 1, a heat dissipation device 3 fixedly connected to the side of the motor housing 2, and a drive device 4 fixedly connected to the inner wall of the motor housing 2.

[0028] The motor base 1 provides overall support and enclosure for the motor, while the motor housing 2 supports the internal components and restricts the cooling oil. The heat dissipation device 3 drives the cooling oil to flow and drives the corresponding components to actively dissipate heat. The corresponding components drive the cooling oil to flow in multiple directions and increase the contact area of ​​the cooling oil. The active air cooling diffuses the heat inside the motor. The corresponding active heat dissipation measures introduce air from the side, thereby reducing the volume required for heat dissipation. The air flows along the side surface of the motor housing 2, further enhancing the heat dissipation effect. The drive device 4 drives the cooling oil to flow while rotating through the corresponding components, thereby removing heat through the thermal conduction of the cooling oil. This achieves active heat dissipation from inside the motor, improving heat dissipation efficiency compared to traditional external heat dissipation methods.

[0029] The heat dissipation device 3 includes a heat dissipation shell 301, a heat dissipation component 302 is fixedly connected to the inner wall of the heat dissipation shell 301, a flow guide component 303 is fixedly connected to the inner wall of the heat dissipation component 302, and a fan component 304 is fixedly connected to the side of the motor base 1 located on one side of the flow guide component 303.

[0030] The heat sink cassette 301 provides overall support, the heat sink component 302 guides the flow of cooling oil, the flow guide component 303 facilitates the flow of internal cooling oil, thereby increasing the circulation speed of the cooling oil, and the fan component 304 provides active air cooling through the gaps of the heat sink component 302, thereby improving the passive cooling efficiency of the heat sink component 302.

[0031] Please see Figures 1-5 The present invention provides a technical solution: the heat dissipation assembly 302 includes a flow guide baffle 3021, a connecting plate 3022 is fixedly connected to the side of the flow guide baffle 3021, a heat dissipation pipe 3023 is fixedly connected to the side of the connecting plate 3022, an inlet 3024 is opened at the end of the side of the heat dissipation pipe 3023 near the flow guide baffle 3021, an outlet 3025 is opened at the end of the heat dissipation pipe 3023 away from the heat dissipation pipe 3023, the side of the heat dissipation pipe 3023 is fixedly connected to the inner wall of the motor base 1, and the side of the heat dissipation pipe 3023 away from the motor base 1 is fixedly connected to the side of the flow guide assembly 303.

[0032] The flow guiding assembly 303 includes an oil guide pipe 3031, a diffuser baffle 3032 fixedly connected to the inner wall of the oil guide pipe 3031, an oil outlet 3033 opened on the side of the oil guide pipe 3031 located on the side of the diffuser baffle 3032, a spiral blade 3034 fixedly connected to the top of the diffuser baffle 3032, an oil supply pipe 3035 sleeved and rotatably connected to the side of the spiral blade 3034, an oil inlet 3036 adapted to the inlet port 3024 opened on the side of the oil supply pipe 3035, the side of the oil guide pipe 3031 communicates with the side of the drive device 4, and the side of the oil supply pipe 3035 is fixedly connected to the side of the heat dissipation pipe 3023.

[0033] The fan assembly 304 includes a fixed baffle 3041, an air inlet 3042 is provided on the side of the fixed baffle 3041, a fan shaft 3043 is rotatably connected to the side of the fixed baffle 3041 via a bracket, a straight fan blade 3044 is fixedly connected to the side of the fan shaft 3043, and an arc-shaped fan blade 3045 is fixedly connected to the side of the straight fan blade 3044 located on the side of the air inlet 3042. The end of the fan shaft 3043 away from the fixed baffle 3041 passes through the side of the motor base 1 and is fixedly connected to the side of the oil guide pipe 3031. The side of the fixed baffle 3041 is fixedly connected to the side of the motor base 1.

[0034] When the motor rotates, the components corresponding to the drive unit 4 drive the oil guide pipe 3031 to rotate, and the components corresponding to the drive unit 4 drive the cooling oil to flow. After entering the oil guide pipe 3031, the cooling oil flows along the inner wall of the oil guide pipe 3031. The rotation of the oil guide pipe 3031 drives the diffuser baffle 3032 to rotate. The cooling oil is released along the oil outlet 3033 under the guidance of the diffuser baffle 3032. Under the driving action of the diffuser baffle 3032, the spiral blade 3034 rotates. The rotation of the spiral blade 3034 drives the cooling oil to flow, so that the cooling oil flows from one end near the drive unit 4 to the other end near the oil inlet 3036. The cooling oil flows out through the side of the oil inlet 3036 and enters the heat dissipation pipe 30 along the inlet 3024. Inside 23, cooling oil flows out through heat dissipation pipe 3023 to outlet 3025. During the flow of cooling oil, oil guide pipe 3031 drives fan shaft 3043 to rotate. The rotation of fan shaft 3043 drives straight fan blade 3044 and arc-shaped fan blade 3045 to rotate. The rotation of arc-shaped fan blade 3045 drives air through air inlet 3042 to the side of straight fan blade 3044. Straight fan blade 3044 drives air through the guide to flow through the gap of heat dissipation pipe 3023. The air carries away the heat inside heat dissipation pipe 3023, thereby reducing the temperature of cooling oil and achieving active cooling. The design of air inlet 3042 reduces the volume required to draw in air, making it easier to dissipate heat from the motor in a narrow working environment.

[0035] Please see Figures 1-7 The present invention provides a technical solution: the driving device 4 includes a driving shaft 401, a sealing ring 402 is sleeved and rotatably connected to the side of the driving shaft 401, a driving assembly 403 is fixedly connected to one end of the driving shaft 401, a stator assembly 404 is sleeved and rotatably connected to the side of the driving assembly 403, a guide groove 405 adapted to the outlet 3025 is opened on the side of the stator assembly 404, the side of the stator assembly 404 is fixedly connected to the inner wall of the motor base 1, and the sealing ring 402 passes through the side of the motor base 1 and is fixedly connected to the side of the motor base 1.

[0036] The drive assembly 403 includes a hollow shaft 4031, a spiral bracket 4032 fixedly connected to the side of the hollow shaft 4031, a cable support seat 4033 fixedly connected to the end of the spiral bracket 4032 away from the hollow shaft 4031, a guide assembly 4034 fixedly connected to the portion of the hollow shaft 4031 located between the spiral brackets 4032, the cable support seat 4033 contacting the inner wall of the stator assembly 404, the side of the hollow shaft 4031 fixedly connected to the side of the drive shaft 401, and the end of the hollow shaft 4031 away from the drive shaft 401 communicating with the side of the oil guide pipe 3031.

[0037] The cable support 4033 and the stator assembly 404 rotate via an inductor. During the rotation of the cable support 4033, the cable support 4033 drives the spiral bracket 4032 to rotate, which in turn drives the hollow shaft 4031 to rotate. The hollow shaft 4031 then drives the guide assembly 4034 to rotate. Simultaneously, the rotation of the spiral bracket 4032 causes the cooling oil to flow, facilitating its flow during motor operation and improving cooling efficiency. Furthermore, the cooling oil, guided by the guide groove 405, returns to the other side of the spiral bracket 4032, thus achieving internal cooling. The cooling oil circulates and lubricates the cable support 4033 and stator assembly 404 during circulation, ensuring stable motor operation. The sealing ring 402 prevents cooling oil leakage. The cooling oil cooperates with the guide groove 405 on the side of the spiral bracket 4032, making the oil circuit circulate from the outside to the inside. The cooling oil re-enters the hollow shaft 4031 through the guide assembly 4034 and is transferred to the oil guide pipe 3031 for re-cooling. Compared with directly flowing horizontally across the side of the spiral bracket 4032, it carries away more heat, thus facilitating heat dissipation from the inside of the motor.

[0038] Please see Figures 1-8 The present invention provides a technical solution: the guide component 4034 includes a triangular tube 40341, an oil delivery hole 40342 is provided on the side of the triangular tube 40341, a guide vane 40343 is fixedly connected to the side of the triangular tube 40341, the bottom of the triangular tube 40341 ​​is connected to the side of the hollow rotating shaft 4031, and the triangular tube 40341 ​​is located on one side of the spiral support 4032.

[0039] When the hollow shaft 4031 rotates, it drives the triangular tube 40341 ​​to rotate. The rotation of the triangular tube 40341 ​​guides the cooling oil through the oil inlet 40342, thereby causing the cooling oil to flow into the interior of the hollow shaft 4031. The cooling oil is then guided along the hollow shaft 4031. When the motor rotates in the opposite direction, the prismatic design of the triangular tube 40341 ​​increases the agitation of the cooling oil, thereby causing the cooling oil to be agitated between the spiral supports 4032. This facilitates the removal of impurities between the spiral supports 4032, and the agitation of multiple cooling oil layers is achieved through the guide vanes 40343, thus facilitating the recycling of the cooling oil.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
