Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a heat dissipation motor. Background Art

[0002] The motor is mainly composed of a stator, a rotor and a driver. The stator, rotor and driver will generate heat during operation. If the heat cannot be dissipated in time, the motor will burn out. Existing heat dissipation motors use an external fan to dissipate heat. Since it is difficult to control the synchronous operation of the motor and the fan, it is easy for the fan to run idle, resulting in high energy consumption. Moreover, the heat can only be dissipated by a single method of blowing air inward or exhausting air outward. In addition, the stator, rotor and driver cannot be dissipated at the same time, resulting in low heat dissipation efficiency and easy motor overheating, thereby shortening the service life of the motor.

[0005] A heat dissipation motor according to an embodiment of the utility model has at least the following beneficial effects: when starting, the rotor drives the shaft to rotate, driving the fan blades to rotate. When the fan blades rotate, the first blade and the second blade are driven to rotate in the same direction, thereby driving air flow, generating airflow in the first air duct and the second air duct. Since the rotation direction of the second blade is opposite to that of the first blade, the airflow directions in the first air duct and the second air duct are opposite, and air can be blown into the first chamber and exhausted outward at the same time, so that convection is formed in the first chamber to improve the heat transfer efficiency, thereby improving the heat dissipation efficiency of the stator and the rotor.

[0032] It is understandable that, referring to Figures 1 to 5The utility model is a heat dissipation motor, comprising a motor body 100, an air cooling mechanism 200 and a liquid cooling mechanism 300. The motor body 100 comprises a housing 110, a stator 120, a rotor 130, a rotating shaft 140 and a driver 160. The housing 110 is provided with a first chamber 111 and a second chamber 112. The stator 120 and the rotor 130 are both arranged in the first chamber 111, and the driver 160 is arranged in the second chamber 112. 0 is provided with a vent 113, the vent 113 is connected to the first chamber 111, the rotating shaft 140 is rotatably connected to the housing 110, the rotor 130 is fixedly connected to the rotating shaft 140, and the stator 120 is fixedly connected to the housing 110; the air cooling mechanism 200 includes a fan blade 210, the fan blade 210 is fixedly connected to the rotating shaft 140, the fan blade 210 is located at the vent 113, and the fan blade 210 is provided with a first air duct 211 and a second air duct 212, the first air duct 211 and the second air duct 212 are connected to the first air duct 211 and the second air duct 212. The two air ducts 212 are arranged along the axial direction of the fan blade 210, and the second air duct 212 surrounds the first air duct 211. A plurality of first blades 213 are arranged in the first air duct 211, and the plurality of first blades 213 are evenly arranged at circumferential intervals along the fan blade 210. A plurality of second blades 214 are arranged in the second air duct 212, and the plurality of second blades 214 are evenly arranged at circumferential intervals along the fan blade 210, and the rotation direction of the second blades 214 is opposite to that of the first blades 213. The liquid cooling mechanism 300 includes a radiator 310, a refrigerator 320 and an oil pump 340. The radiator 310 is arranged on the driver 160, and the refrigerator 320 and the oil pump 340 are both connected to the housing 110. The radiator 310 is used to absorb heat from the driver 160. The oil pump 340 is connected to an oil pipe 330. The radiator 310 and the refrigerator 320 are closed-loop connected through the oil pipe 330, and the refrigerator 320 is used to cool the oil in the oil pipe 330.

[0033] During startup, the rotor 130 drives the rotating shaft 140 to rotate, driving the fan blades 210 to rotate. When the fan blades 210 rotate, the first blades 213 and the second blades 214 rotate in the same direction, thereby driving the air flow, so that airflow is generated in the first air duct 211 and the second air duct 212. Since the rotation direction of the second blade 214 is opposite to that of the first blade 213, the airflow directions in the first air duct 211 and the second air duct 212 are opposite, and air can be blown into the first chamber 111 and drawn out at the same time, so that convection is formed in the first chamber 111 to improve the heat transfer efficiency, thereby The heat dissipation efficiency of the stator 120 and the rotor 130 is improved. Since the fan blades 210 rotate synchronously with the shaft 140, the idling operation of the external fan can be avoided to reduce energy consumption. In addition, the heat of the driver 160 is absorbed by the radiator 310, and the radiator 310 transfers the absorbed heat to the oil. The oil in the oil pipe 330 is cooled by the refrigerator 320, and the oil pump 340 is used to drive the oil in the oil pipe 330 to circulate between the radiator 310 and the refrigerator 320, so that the driver 160 can be circulated and cooled to improve the heat dissipation efficiency.

[0034] It should be noted that the rotation directions of the multiple first blades 213 are the same, and the rotation directions of the multiple second blades 214 are also the same. Since the forward and reverse rotation of the heat dissipation motor drives the fan blades 210 to rotate forward and reverse synchronously, the airflow in the first air duct 211 flows into the first chamber 111 while the airflow in the second air duct 212 flows out of the first chamber 111, or the airflow in the first air duct 211 flows out of the first chamber 111 while the airflow in the second air duct 212 flows into the first chamber 111, and since the second air duct 212 surrounds the first air duct 211, two modes of two-way air supply can be achieved, one of which is blowing in the middle of the fan blades 210 and exhausting air on the periphery, and the other is exhausting air in the middle of the fan blades 210 and blowing air on the periphery, so that the airflow in the first chamber 111 also forms convection in two directions, thereby improving the heat dissipation efficiency.

[0035] The same number of first blades 213 and second blades 214 can be set to balance the driving force of the first blades 213 and the second blades 214 on the air, so as to balance the blowing and exhausting efficiency, thereby improving the stability of the air supply, and making the radial force of the fan blades 210 balanced when rotating, thereby improving the stability of the rotation of the fan blades 210.

[0036] It is understandable that, referring to Figures 1 to 4The air cooling mechanism 200 further includes a conical air guide cover 220, which is connected to the fan blade 210. Along the axial direction of the fan blade 210, the diameter of the conical air guide cover 220 gradually increases in a direction away from the fan blade 210. The conical air guide cover 220 is coaxially arranged with the fan blade 210. An air guide channel 221 is formed inside the conical air guide cover 220, and the air guide channel 221 is connected to the first air duct 211. Since the diameter of the conical air guide cover 220 gradually increases in a direction away from the fan blade 210 along the axial direction of the fan blade 210, an air guide channel 221 is formed inside the conical air guide cover 220, and the airflow is guided to expand outward or collect air in the first air duct 211 through the inner wall of the air guide channel 221, and the airflow blown out from the second air duct 212 is guided to expand outward through the outer wall of the conical air guide cover 220. In addition, the conical air guide cover 220 separates and guides the airflow near the fan blade 210 to pass through the first air duct 211 and the second air duct 212 respectively, which can reduce the mutual influence between the two-way airflows, thereby improving the stability of air supply.

[0037] Specifically, refer to Figure 3 and Figure 4 The conical air guide cover 220 is provided with an annular air guide portion 222 at the end edge away from the fan blade 210, and the annular air guide portion 222 extends radially outwardly of the fan blade 210. Since the annular air guide portion 222 extends radially outwardly of the fan blade 210, the airflow blown out from the second air duct 212 can be guided to diffuse radially outwardly of the fan blade 210, which can further reduce the mutual influence between the two-way airflows, thereby improving the stability of air supply.

[0038] Specifically, refer to Figure 1 and Figure 3 , both axial sides of the fan blade 210 are connected with a conical air guide cover 220, and the conical air guide cover 220 near the stator 120 extends into the first chamber 111. By connecting the conical air guide cover 220 to both axial sides of the fan blade 210, the airflow on both axial sides of the fan blade 210 can be guided, thereby reducing the mutual influence between the two-way airflows to improve the stability of air supply, and by extending the conical air guide cover 220 near the stator 120 into the first chamber 111, the conical air guide cover 220 separates and guides the airflow, so that two airflows flowing through the middle and side walls of the first chamber 111 can be formed in the first chamber 111, and convection is formed in the first chamber 111, thereby improving the heat exchange efficiency, and then improving the heat dissipation efficiency of the stator 120 and the rotor 130.

[0039] Specifically, refer to Figures 2 to 4The conical air guide cover 220 is provided with an annular mounting portion 223, and the fan blade 210 is provided with an annular positioning portion 215 protruding along the axial direction, and the annular mounting portion 223 is sleeved on the annular positioning portion 215. By sleeve-fitting the annular mounting portion 223 on the annular positioning portion 215, the radial position of the conical air guide cover 220 can be pre-positioned, so that the conical air guide cover 220 and the fan blade 210 are coaxial, thereby facilitating the installation and positioning of the conical air guide cover 220, and reducing the position shaking and rotation resistance of the conical air guide cover 220 during the rotation process, thereby improving the rotation stability of the conical air guide cover 220.

[0040] It should be noted that the annular mounting portion 223 may be fixedly connected to the annular positioning portion 215 by welding or bolting.

[0041] Specifically, refer to Figures 2 to 4 The inner side wall of the annular mounting portion 223 is provided with a plurality of slots 224, which are evenly arranged at intervals along the circumference of the annular mounting portion 223, and the outer side wall of the annular positioning portion 215 is provided with a plurality of blocks 216, which correspond to the slots 224 one by one, and the blocks 216 can be snapped into the slots 224. By snapping the blocks 216 into the slots 224, the circumferential position of the conical air guide cover 220 can be pre-positioned, which facilitates the pre-positioning of the annular mounting portion 223, and because the plurality of slots 224 are evenly arranged at intervals along the circumference of the annular mounting portion 223, the blocks 216 correspond to the slots 224 one by one, which can make the annular mounting portion 223 balanced in force along the circumferential direction, thereby improving the connection stability between the annular mounting portion 223 and the annular positioning portion 215.

[0042] It is understandable that, referring to Figure 1 A filter screen 150 is provided in the first chamber 111, and the vent 113 is connected to the first chamber 111 through the filter screen 150. By filtering dust and other particulate impurities in the air through the filter screen 150, it is possible to reduce the amount of external dust and other particulate impurities entering the first chamber 111 and accumulating on the stator 120 and the rotor 130, thereby improving the operating stability of the stator 120 and the rotor 130, and reducing the influence of dust and other particulate impurities on the heat dissipation efficiency.

[0043] It is understandable that, referring to Figure 1 and Figure 5The driver 160 includes a plurality of components 161 and a circuit board 162. The components 161 are electrically connected to the circuit board 162. The heat sink 310 is connected to the circuit board 162. The heat sink 310 has a long strip shape. The outer wall of the heat sink 310 is provided with a plurality of positioning grooves 311. The plurality of positioning grooves 311 are evenly spaced along the length direction of the heat sink 310. The positioning grooves 311 correspond to the components 161 one by one, and the components 161 are embedded in the positioning grooves 311. By distributing a plurality of positioning grooves 311 at equal intervals along the length direction of the heat sink 310 and embedding the components 161 in the positioning grooves 311, the plurality of components 161 can be dispersedly arranged on the heat sink 310 and exchange heat with the heat sink 310 individually, which can reduce the mutual influence of heat exchange between the components 161, thereby improving the heat exchange efficiency between the components 161 and the heat sink 310, and by embedding the components 161 in the positioning grooves 311, the inner walls of the positioning grooves 311 can abut against the components 161, which can increase the contact area between the components 161 and the heat sink 310, thereby improving the heat exchange efficiency, thereby improving the heat dissipation efficiency of the driver 160. In addition, by fixing the position of the components 161 through the positioning grooves 311, the stability of the installation position of the components 161 can be improved.

[0044] Specifically, refer to Figure 6 and Figure 7 The radiator 310 is provided with an infusion channel 312, which is arranged along the length direction of the radiator 310, and the inner wall of the infusion channel 312 is provided with a spiral heat sink 313. By providing the spiral heat sink 313 on the inner wall of the infusion channel 312, the contact area between the inner wall of the infusion channel 312 and the oil can be increased, thereby improving the heat exchange efficiency between the radiator 310 and the oil, and the spiral heat sink 313 blocks and guides the flow of the oil, so that a vortex can be formed in the infusion channel 312, slowing down the flow rate of the oil, thereby improving the heat exchange efficiency and heat exchange amount between the radiator 310 and the oil, and further improving the heat dissipation efficiency of the driver 160.

[0045] Specifically, refer to Figure 6 and Figure 7 The spiral heat sink 313 is provided with a plurality of through holes 314, and the plurality of through holes 314 are arranged at equal intervals along the spiral direction of the spiral heat sink. By providing a plurality of through holes 314 in the spiral heat sink 313, the oil can flow through the through holes 314, and the contact area between the spiral heat sink 313 and the oil can be increased, thereby improving the heat exchange efficiency between the radiator 310 and the oil. Furthermore, by arranging the plurality of through holes 314 at equal intervals along the spiral direction of the spiral heat sink, the heat exchange efficiency can be improved while ensuring the structural strength, so as to reduce the possibility of deformation of the spiral heat sink 313 due to the impact of the oil.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
