Description

Technical Field

[0001] The present invention relates to the technical field of motor heat dissipation, and in particular to a silicon chip heat dissipation structure for a motor. Background Art

[0002] When a motor is used for a long time, it will generate a lot of heat, which will not only affect the normal use of the motor but also affect the performance of the motor itself, thus reducing the service life of the motor. Therefore, it is necessary to cool the motor during operation. At present, when the motor is powered on, the heat of the motor winding is mainly dissipated in two ways:

[0003] 1. Heat is transferred from the inner surface of the insulation layer to the outer surface by solid conduction, then to the stator core, and finally to the motor housing.

[0004] 2. Heat is transferred from the surface of the winding end to the motor housing by air convection.

[0005] Therefore, the traditional heat dissipation methods are:

[0006] 1. Add ventilation holes on the motor end cover to increase the heat conduction area and reduce the temperature rise, but it also reduces the protection level of the motor.

[0007] 2. Adding a fan to the tail of the motor increases the air convection coefficient and reduces the motor temperature rise. However, the fan will increase the structural space requirements and torque output requirements of the motor. The traditional heat dissipation method not only reduces the protection level of the motor but also changes the size of the motor. At the same time, the motor will generate vibration and noise when rotating, which will inevitably affect the motor operation and working environment. Therefore, we propose a silicon chip heat dissipation structure for the motor to solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to solve the shortcomings in the prior art that the traditional heat dissipation method reduces the protection level of the motor and changes the size of the motor. At the same time, the motor will generate vibration and noise when rotating, which will inevitably affect the operation of the motor and the working environment. A silicon chip heat dissipation structure for the motor is proposed.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A silicon chip heat dissipation structure for a motor includes a fixed cover for fixing the motor, a shock-absorbing mechanism is provided in the fixed cover, a sound insulation mechanism is provided on the fixed cover, a motor housing is provided on the shock-absorbing mechanism, a heat dissipation mechanism is provided in the motor housing for dissipating heat from the motor, and the motor housing includes a transmission shaft, a rotor assembly, a motor winding and a stator core for motor operation. The heat dissipation mechanism can be used to dissipate heat from the motor without changing the overall size of the motor, and there is no need to open ventilation holes on the housing, thereby not reducing its protection level. The shock-absorbing mechanism can prevent the vibration generated by the motor from affecting the operation of the motor, and the sound insulation mechanism can absorb noise to avoid affecting the working environment.

[0011] Preferably, the heat dissipation mechanism includes a heat dissipation silicon chip for dissipating heat from the motor. The outer wall and inner wall of the heat dissipation silicon chip are fixedly connected to the inner wall of the motor housing and one side of the motor winding, respectively. Through the heat dissipation silicon chip, the size of the heat dissipation silicon chip can be matched according to the size of the motor, and filled in the gap between the motor winding and the motor housing. Therefore, it can be said that the heat dissipation function of the motor is increased without changing the overall size of the motor, and there is no need to open ventilation holes on the housing. For a closed motor, its protection level will not be reduced.

[0012] Preferably, the shock absorbing mechanism includes a plurality of shock absorbing dampers and a shock absorbing plate, the top and bottom ends of the plurality of shock absorbing dampers are fixedly connected to the bottom inner wall of the fixed cover and the bottom of the shock absorbing plate respectively, the bottom of the motor housing is fixedly connected to the top of the shock absorbing plate, and the two sides of the shock absorbing plate are slidably connected to the two side inner walls of the fixed cover. The shock absorbing plate and the shock absorbing damper can prevent the vibration generated by the motor from affecting the operation of the motor.

[0013] Preferably, the stator core is provided with slot insulation paper for insulation, and the slot insulation paper is located between the stator core and the motor winding, and the slot insulation paper prevents contact friction between the motor winding and the stator core.

[0014] Preferably, the sound insulation mechanism includes two sound insulation boards and two sound-absorbing cottons for sound insulation of the motor. The bottoms of the two sound insulation boards are fixedly connected to the top sides of the fixed cover, and one side of the two sound-absorbing cottons is fixedly connected to one side of the two sound insulation boards. The sound insulation boards and the sound-absorbing cottons absorb the noise generated by the motor to prevent it from affecting the working environment.

[0015] Preferably, the material of the sound-absorbing cotton and the material of the sound insulation board are polyester fiber sound-absorbing cotton and wood fiber sound insulation board respectively. The wood fiber sound insulation board and polyester fiber sound-absorbing cotton can absorb noise more effectively.

[0016] Preferably, multiple grooves are provided on the inner walls on both sides of the fixed cover, and multiple sliders are fixedly connected to both sides of the shock-absorbing plate. One side of the multiple sliders is slidably connected to the inner walls of the multiple grooves. Through the sliders and grooves, the shock-absorbing plate can reduce friction when sliding longitudinally, and slide more smoothly.

[0017] Beneficial effect: Through the heat dissipation silicon chip, the size of the heat dissipation silicon chip can be matched according to the size of the motor, and it is filled in the gap between the motor winding and the motor housing. Therefore, it can be said that the heat dissipation function of the motor is increased without changing the overall size of the motor, and there is no need to open ventilation holes on the housing. For enclosed motors, it does not reduce its protection level.

[0018] The vibration damper is set to prevent the vibration generated by the motor from affecting the motor operation;

[0019] Because sound-absorbing cotton is set up, it absorbs noise and avoids affecting the working environment.

[0020] The present invention has a reasonable structure. Through the heat dissipation mechanism, the heat dissipation of the motor can be carried out without changing the overall size of the motor. At the same time, there is no need to open ventilation holes on the outer shell, so as not to reduce its protection level. The shock absorption mechanism can prevent the vibration generated by the motor from affecting the operation of the motor. The sound insulation mechanism can absorb the noise, which can avoid affecting the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of grooves 13 are provided on the inner walls on both sides of the cover 3, and a plurality of sliders 12 are fixedly connected to both sides of the shock-absorbing plate 10.

A sound insulation mechanism is provided on the fixed cover 3, and the sound insulation mechanism includes two sound insulation boards 1 and two sound-absorbing cottons 11 for sound insulation of the motor. The bottoms of the two sound insulation boards 1 are fixedly connected to the two sides of the top of the fixed cover 3, and one side of the two sound-absorbing cottons 11 is fixedly connected to one side of the two sound insulation boards 1. The noise generated by the motor is absorbed by the sound insulation board 1 and the sound absorbing cotton 11 to avoid affecting the working environment. The materials of the sound absorbing cotton 11 and the sound insulation board 1 are polyester fiber sound absorbing cotton 11 and wood wool sound insulation board 1 respectively. The wood wool sound insulation board 1 and the polyester fiber sound absorbing cotton 11 can absorb noise more effectively. A motor housing 2 is provided on the shock absorption mechanism. A heat dissipation mechanism for heat dissipation of the motor is provided in the motor housing 2. The heat dissipation mechanism includes a heat dissipation silicon chip 7 for heat dissipation of the motor. The outer wall and the inner wall of the heat dissipation silicon chip 7 are fixedly connected to the inner wall of the motor housing 2 and one side of the motor winding 6 respectively. Through the heat dissipation silicon chip 7, the heat dissipation The size of the thermal silicon chip 7 can be matched according to the size of the motor and filled in the gap between the motor winding 6 and the motor housing 2. Therefore, it can be said that the heat dissipation function of the motor is increased without changing the overall size of the motor, and there is no need to open ventilation holes on the housing.

[0032] Working principle of the present invention: When the motor starts to rotate, heat is generated inside the motor. Since a heat dissipation silicon chip 7 is added between the surface of the motor winding 6 and the motor housing 2, the heat of the motor winding 6 is conducted to the motor housing 2 in a more efficient manner, thereby increasing the heat dissipation performance of the motor itself, thereby achieving the effect of reducing temperature rise.

At the same time, the motor will generate noise when rotating. Since a sound insulation board 1 and sound-absorbing cotton 11 are provided, the material of the sound-absorbing cotton is polyester fiber sound-absorbing cotton 11, which can effectively absorb noise, thereby avoiding affecting the working environment.
