Description

Technical Field

[0001] The invention belongs to the technical field of roller drive motors, and in particular relates to a heat dissipation type roller drive motor and a heat dissipation structure. Background Art

[0002] The principle of the roller drive motor driving the roller is to transmit the power of the high-speed rotation of the motor to the roller through the reducer, thereby driving the roller to work. This method has the advantages of large driving power, high transmission efficiency, and stable speed. However, heat will be generated during the high-speed rotation of the output shaft, and the heat cannot be dissipated in time, which will cause damage to the internal parts of the motor;

[0003] The commonly used heat dissipation methods for roller drive motors are natural cooling and air cooling. Natural cooling relies on the hardware structure of the drive motor itself and dissipates heat from the inside to the outside through metal materials, and the heat dissipation is slow. Air cooling is achieved by installing a cooling fan on the drive motor to form active heat dissipation. Cold air is blown into the motor to take away the heat, and then discharged after taking it away. However, in this method, a fast fan speed will generate loud noise, and a slow fan speed will result in poor heat dissipation. When the roller drive motor dissipates heat, there is a problem that there is no design that utilizes the pressure difference between the inside and outside of the motor housing to form convective heat exchange heat dissipation. For this reason, the present application proposes a heat dissipation type roller drive motor and a heat dissipation structure. Summary of the invention

[0004] The object of the present invention is to provide a heat dissipation type roller drive motor and a heat dissipation structure to solve the problem that the roller drive motor proposed in the above background technology does not utilize the pressure difference between the inside and outside of the motor housing to form convection heat exchange and heat dissipation.

[0005] To achieve the above object, the present invention provides the following technical solution: a heat dissipation type roller drive motor, comprising

[0025] Example

[0026] See also Figures 1 to 3The present invention provides a technical solution: a heat dissipation type roller drive motor, comprising a motor bracket, comprising a base 21, a column 22 connected to the base 21 at the bottom end, and a support plate 23 connected to the top of the column 22 on the bottom surface, the column 22 is combined with the base 21 and the support plate 23 by a conventional method, and the support plate 23 is combined with the roller drive motor 1 by conventional means; the roller drive motor 1 installed on the support plate 23 is provided with a drive shaft 11, the drive shaft 11 is connected to the roller member, and the roller drive motor The machine 1 drives the roller and the drive shaft 11 to rotate. The method of using the roller drive motor 1 is a conventional technical means, which will not be described in detail in this application; the heat dissipation component includes a micro-tube heat exchanger 7 installed on the base 21, an air storage ring 3 sleeved on the outside of the drive shaft 11, and a heat conduction component, which includes a heat transfer copper tube 8 with one end inserted into the inside of the air storage ring 3, a connecting copper plate 9 connected to the other end of the heat transfer copper tube 8, and a heat conduction copper tube 10 installed on the outside of the connecting copper plate 9. The micro-tube heat exchanger 7 is provided with a conventional tube The micro-tube heat exchanger 7 uses conventional two fluids to exchange heat through a fixed tube bundle to achieve heat exchange, which is not described in detail in this application. The heat in the roller drive motor 1 is conducted to the connecting copper plate 9 and the heat-conducting copper tube 10. The surface temperature of the connecting copper plate 9 and the heat-conducting copper tube 10 increases, and the cooling fan blows in cold air. The cold air brings the high temperature on the surface of the connecting copper plate 9 and the heat-conducting copper tube 10 and part of the heat inside the roller drive motor 1 into the gas storage ring 3. The hot air is stored inside the gas storage ring 3, and then the hot air fluid is blown along the connecting copper plate 9 and the heat-conducting copper tube 10. The connecting pipe 32 enters the micro-tube heat exchanger 7 to realize heat exchange. The air pressure in the air storage ring 3 is lower than the air pressure in the roller drive motor 1, which is conducive to the formation of convection, so that the heat on the surface of the connecting copper plate 9 and the heat-conducting copper tube 10 is taken away. The air storage ring 3 is provided with a connecting pipe 32 connected to the micro-tube heat exchanger 7. The surface of the air storage ring 3 facing the roller drive motor 1 is provided with a sleeve 31 sleeved on the outside of the heat transfer copper tube 8. The heat transfer copper tube 8 and the sleeve 31 are hollow structures, and cold air can circulate from the inside of the heat transfer copper tube 8 and the sleeve 31.

[0028] In this embodiment, the heat-conducting copper tube 10 is in a spiral shape, the interior of the heat-conducting copper tube 10 is hollow, and both ends of the heat-conducting copper tube 10 are sealed to prevent air from entering the interior of the heat-conducting copper tube 10. The spiral heat-conducting copper tube 10 is long and has more contact parts with the shell of the roller drive motor 1, which is beneficial to heat conduction.

Heat can be conducted to the heat-conducting ring 33 along the heat-conducting copper tube 8. When the heat of the heat-conducting ring 33 is taken away, under the action of heat exchange, the heat at one end of the heat-conducting copper tube 8 with high heat is conducted to the heat-conducting ring 33 with low heat, which is beneficial to heat dissipation.

[0030] In this embodiment, a heat dissipation groove 12 with an isosceles trapezoidal cross section is provided on the outer surface of the roller driving motor 1 to limit the heat dissipation box 6 .

[0031] To sum up: heat is generated inside the roller drive motor 1, and the heat on the shell of the roller drive motor 1 is transferred to the heat-conducting copper tube 10, the connecting copper plate 9 and the heat-conducting copper tube 8. The cooling fan blows in cold air, and the cold air brings the high temperature on the surface of the connecting copper plate 9 and the heat-conducting copper tube 10 and part of the heat inside the roller drive motor 1 into the air storage ring 3. The hot air is stored inside the air storage ring 3, and then the hot air fluid enters the micro-tube heat exchanger 7 along the connecting pipe 32 to realize heat exchange. The air pressure in the air storage ring 3 is lower than the air pressure in the roller drive motor 1, which is conducive to the formation of convection, so that the heat on the surface of the connecting copper plate 9 and the heat-conducting copper tube 10 is taken away.

[0032] A heat dissipation structure applied to a heat dissipation type roller drive motor comprises a heat dissipation ring 5 installed on the outside of the roller drive motor 1, and a heat dissipation box 6 connected to the inside of the heat dissipation ring 5.

The heat dissipation ring 5 is connected to an external conventional inflation device, such as a vacuum pump. Gas is injected into the heat dissipation ring 5 from the air inlet pipe 51, and the gas is discharged from the air outlet pipe 52. The air pressure between the heat dissipation box 6 and the roller drive motor 1 is reduced, and external air enters from the air hole 61 to form an air flow channel. Air flow occurs under the action of air pressure, so that the heat on the surface of the roller drive motor 1 is dissipated.

Air holes 61 are opened on the surface of the connecting plate 62, and the abutment plates 64 and the inclined plates 63 are in contact with the surface of the shell of the roller drive motor 1, which is conducive to dissipating heat.

[0035] The working principle and use process of the present invention:

[0036] The heat dissipation ring 5 is connected to a conventional external inflation device, such as a vacuum pump. Gas is injected into the heat dissipation ring 5 from the air inlet pipe 51, and the gas is discharged from the air outlet pipe 52. The air pressure between the heat dissipation box 6 and the roller drive motor 1 is reduced, and the external air enters from the air hole 61 to form an air flow channel.
