Description

Technical Field

[0001] The present invention relates to the technical field of high-speed motors, and in particular to a high-speed motor capable of adaptively adjusting cooling efficiency. Background Art

[0002] Modern industry has increasingly higher performance requirements for motors. Traditional motors can no longer meet the needs of certain specific application scenarios in terms of speed, efficiency, noise control, and compactness. Therefore, high-speed motors have emerged and become an important direction for the development of motor technology. High-speed motors have achieved a significant increase in speed and efficiency by optimizing electromagnetic design, material selection, and manufacturing processes, providing strong support for the upgrading of industrial equipment.

[0003] For example, the Chinese patent with announcement number: CN215772780U, patent name: A heat dissipation structure of a magnetically levitation asynchronous high-speed motor, and announcement date: 2022-02-08, includes a motor and an end cover, both ends of the motor are provided with end covers, the motor is wrapped with a water pipe, one end of the water pipe is connected to a solenoid valve, and the solenoid valve is electrically connected to a control module fixed to the end cover. Through the coordinated use of water pipes, solenoid valves, control modules, sensors, etc., the use of condensed water can be automatically regulated according to the temperature of the motor to reduce the waste of resources. Through the coordinated use of curved pipes, control valves, water pumps, liquid storage tanks, etc., the solution in the liquid storage tank is introduced into the curved pipe by a water pump, and the solution in the curved pipe enters the water pipe through a three-way pipe. The solution cleans the inner wall of the water pipe to prevent the formation of scale.

[0004] The above-mentioned prior art has the following technical problems: when the existing high-speed motor is dissipating heat, heat is exchanged through the heat dissipation fins arranged thereon. However, after long-term use, a certain amount of dust and impurities are easily attached to the surface of the heat dissipation fins. The adhesion of these impurities is likely to affect the subsequent heat exchange efficiency between the heat dissipation fins and the outside air. At the same time, when the motor is working, it is not convenient to adjust the cooling efficiency of the motor according to the actual temperature of the motor. When the motor is in the normal temperature range and the heat dissipation structure excessively cools the motor, it is easy to affect the overall working performance of the motor.

[0005] Therefore, we propose a high-speed motor with adaptive cooling efficiency to solve the above problems. Summary of the invention

However, after long-term use, the surfaces of the cooling fins are prone to adhere to certain dust and impurities. The adhesion of these impurities is likely to affect the subsequent heat exchange efficiency between the cooling fins and the outside air. At the same time, when the motor is working, it is not convenient to adjust the cooling efficiency of the motor according to the actual temperature of the motor.

A cleaning groove is formed on the moving ring. The cleaning groove is located outside the heat dissipation fins. Electromagnets are installed on one side of each of the two moving rings facing each other. A guiding column is fixed on one of the moving rings. A power rod is inserted into the guiding column. One end of the power rod extending out of the guiding column is connected to the other moving ring. The end of the power rod away from the moving ring divides the inside of the guiding column into a first air storage groove and a second air storage groove.

When the high-speed motor body generates heat, the heat is absorbed by the heat sink and then exchanges heat with the outside air, thereby achieving cooling. At the same time, when the motor is working, water is injected into the water inlet ring. The water source inside the water inlet ring can enter the water outlet ring through the water pipe and the guide cover. The circulating flow of the water source can achieve water cooling of the high-speed motor body. 2.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0028] Example 1: Please refer to Figure 1-Figure 9When the existing high-speed motor is dissipating heat, heat is exchanged through the heat dissipation fins arranged thereon. However, after long-term use, the surface of the heat dissipation fins is prone to adhere to certain dust and impurities. The adhesion of these impurities is likely to affect the subsequent heat exchange efficiency between the heat dissipation fins and the outside air. In order to solve this technical problem, the present embodiment discloses the following technical content: a high-speed motor with adaptive cooling efficiency, comprising a high-speed motor body 1, an output shaft 2 is installed in the middle of the high-speed motor body 1, and a dustproof mesh cover 3 is fixed on the back of the high-speed motor body 1, and a surface of the high-speed motor body 1 is equipped with a heat exchange and cooling device for cooling with the outside air. The heat sink 4 is provided with a water cooling component 5, and a temperature sensor is provided on the high-speed motor body 1. The high-speed motor body 1 is provided with an air cooling cleaning component 6, and the air cooling cleaning component 6 is electrically connected to the temperature sensor. The heat sink 4 is evenly distributed in the circumferential direction of the high-speed motor body 1. Each heat sink fin 4 is made of copper material, and the longitudinal section of the heat sink fin 4 is rectangular. The water cooling component 5 includes a water inlet collar 501, a water outlet collar 502, a water pipe 503, a guide cover 504, a water inlet pipe 505 and a water outlet pipe 506, and the water inlet collar 501 The water inlet ring 501 and the water outlet ring 502 are installed on the high-speed motor body 1, and the water inlet ring 501 and the water outlet ring 502 are connected to each other through the water pipe 503 and the guide cover 504, and the water inlet ring 501 is installed with a water inlet pipe 505, and the water outlet ring 502 is installed with a water outlet pipe 506, and the water inlet pipe 505 and the water outlet pipe 506 are both connected to the external refrigeration water tank, and the water pipe 503 and the guide cover 504 are evenly distributed between the water inlet ring 501 and the water outlet ring 502, and the interior of the water inlet ring 501 and the water outlet ring 502 are both set as hollow structures, and the two mobile rings 601 are installed on the high-speed motor body 1. On the motor body 1, the moving ring 601 is connected to each other through the auxiliary spring 602 and the deflector 504, and a cleaning groove 603 is opened on the moving ring 601, the cleaning groove 603 is located on the outside of the heat sink 4, and electromagnets 604 are installed on the opposite sides of the two moving rings 601, the electromagnets 604 on the two moving rings 601 are located on the same straight line, and the magnetism of the electromagnets 604 on the two moving rings 601 is opposite after being energized, the inner wall of the cleaning groove 603 opened on the moving ring 601 and the outer wall of the heat sink 4 are in contact with each other, and the cleaning groove 603 on the moving ring 601 corresponds one by one to the heat sink fin 4.

[0029] The water inlet pipe 505 and the water outlet pipe 506 are connected to the external refrigeration water tank. When the high-speed motor body 1 is working normally, the heat of the high-speed motor body 1 is absorbed by the heat dissipation fins 4. After absorbing the heat, the heat dissipation fins 4 can exchange heat with the external air for cooling. At the same time, the water source in the water tank is injected into the water inlet pipe 505 through the pump body. The water source in the water inlet pipe 505 can be transmitted to the water outlet ring 502 through the water inlet collar 501, the water delivery pipe 503 and the guide cover 504. The water source in the water outlet collar 502 flows back to the inside of the external water tank through the water outlet pipe 506, so as to realize circulating water cooling. When the temperature sensor detects that the high-speed motor body When the temperature of the body 1 is abnormal, the temperature sensor controls the electromagnet 604 to open and close intermittently. When the electromagnet 604 on the two moving rings 601 is energized, the moving rings 601 can be brought closer to each other under the action of magnetic force. When the electromagnet 604 is powered off, the two moving rings 601 will be reset under the action of the auxiliary spring 602, thereby realizing the reciprocating movement of the moving ring 601. The reciprocating movement of the moving ring 601 can be used to clean the impurities and dust attached to the surface of the heat sink fin 4 through the cleaning groove 603 thereon, so as to avoid the adhesion of impurities that easily affects the subsequent heat exchange efficiency between the heat sink fin 4 and the outside air.

[0030] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. When the motor is working, it is not convenient to adjust the cooling efficiency of the motor according to the actual temperature of the motor. When the motor is in the normal temperature range and the heat dissipation structure cools the motor excessively, it is easy to affect the overall working performance of the motor. In order to further solve this technical problem, this embodiment discloses the following technical content, wherein a guide column 605 is fixed on one of the moving rings 601, a power rod 606 is inserted into the inside of the guide column 605, and one end of the power rod 606 extending out of the inside of the guide column 605 is connected to the other moving ring 601, and the power rod 606 is far One end away from the movable ring 601 divides the interior of the guide column 605 into a first air storage groove 607 and a second air storage groove 608, and the sides of the first air storage groove 607 and the second air storage groove 608 are provided with blowing holes 609, and a rubber ring is fixed circumferentially at one end of the power rod 606 located inside the guide column 605, and the power rod 606 can slide on the guide column 605, and the interior of the guide column 605 is set to a hollow structure, and the first air storage groove 607 and the second air storage groove 608 inside the guide column 605 are interconnected with the outside through the blowing holes 609, and there are multiple blowing holes 609 evenly distributed circumferentially in the first air storage groove 607 and the second air storage groove 608.

[0031] When the temperature sensor senses that the working temperature of the high-speed motor body 1 is abnormal, the intermittent power-on and power-off of the electromagnet 604 can make the moving ring 601 move relatively. After the two moving rings 601 move relatively, the power rod 606 on one moving ring 601 can move in the guide column 605 on the other moving ring 601. When the two moving rings 601 move toward the center direction of the high-speed motor body 1, the power rod 606 can squeeze the airflow inside the first air storage groove 607 outward through the blowing hole 609, and the second air storage groove 608 can absorb the outside air through the blowing hole 609. When the moving ring 601 moves toward the center direction of the high-speed motor body 1, the power rod 606 can squeeze the airflow in the second air storage groove 608 outward through the blowing hole 609. The air hole 609 is squeezed outward, and the first air storage groove 607 absorbs the external air through the blowing hole 609, thereby rotating back and forth, and the first air storage groove 607 and the second air storage groove 608 inhale and exhaust air around the heat sink 4, thereby improving the cooling effect of the heat sink 4. At the same time, the air flow rate around the heat sink 4 can be accelerated when blowing, so as to avoid the slow air flow rate around the heat sink 4, which causes the accumulation of heat energy and affects the heat exchange effect of the heat sink 4. In this way, the heat dissipation effect of the high-speed motor body 1 is further increased on the basis of water cooling, so that the high-speed motor body 1 is only cooled by water during normal operation, and is cooled by a combination of water cooling and air blowing when the temperature is abnormal, so as to achieve the purpose of adjusting the cooling efficiency of the motor by the actual temperature of the motor.
