Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a high-speed motor with a cooling structure. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It is mainly composed of a stator and a rotor. Through the principle of electromagnetic induction, when current passes through the stator winding, a rotating magnetic field is generated, which in turn drives the rotor to rotate. Motors are widely used in many fields such as modern industry, transportation, and household appliances.

[0003] The speed of a high-speed motor often exceeds 10,000 rpm when in use. High-speed rotation can achieve higher power output, but high-speed rotation also makes various internal losses relatively large, such as electromagnetic loss, mechanical friction loss, etc., which will increase, resulting in more heat generation. Currently, high-speed motors are mostly cooled by fans, and the heat dissipation efficiency is not high enough. After the motor continues to work, it is easy to accumulate heat inside. Excessive temperature may cause the winding insulation inside the motor to age and fail, affecting the life of the motor, and even causing damage to the motor. Therefore, those skilled in the art provide a high-speed motor with a cooling structure to solve the problems raised in the above background technology. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Please see attached Figures 1 to 4 As shown, a high-speed motor with a cooling structure in an embodiment of the utility model includes a shell 1, the interior of the shell 1 is rotatably connected to a rotating shaft 6 whose front end extends out of the shell 1, the inner side of the rotating shaft 6 is fixedly sleeved with a rotor 8, and the interior of the shell 1 is fixedly provided with a stator 9. The principle of this high-speed motor adopts the existing technology. Specifically, the magnetic field generated by the winding on the stator 9 interacts with the conductor or winding on the rotor 8, so that the rotor 8 is subjected to a torque, thereby starting to rotate, and converting electrical energy into mechanical energy.

[0028] A cooling jacket 10 is fixedly connected to the inner wall of the outer shell 1. The cooling jacket 10 is sleeved on the outside of the stator 9. A cooling cavity 11 surrounding the cooling jacket 10 is opened inside the cooling jacket 10. The cooling jacket 10 is in contact with the stator 9. The cooling cavity 11 is used to circulate coolant, thereby performing efficient heat exchange through the coolant and quickly cooling the motor.

[0029] A heat dissipation component 2 is provided on the outer surface of the shell 1, and a blowing component 3 is connected to the end of the shell 1 away from the front end of the rotating shaft 6. A circulation box 7 is connected to the bottom of the shell 1. The heat dissipation component 2 is provided to dissipate heat and cool the coolant, thereby ensuring that the coolant can work effectively. The blowing component 3 is provided to blow air flow to the heat dissipation component 2, thereby accelerating the heat dissipation efficiency. The circulation box 7 is provided to circulate the coolant.

[0030] The heat dissipation component 2 includes a spiral heat dissipation tube 22, which is sleeved on the outer end of the shell 1. The outer end of the spiral heat dissipation tube 22 is fixedly sleeved with multiple heat dissipation fins 21, and the heat dissipation fins 21 are fixedly connected to the shell 1. When the heat dissipation component 2 is working, the coolant enters the spiral heat dissipation tube 22. Since the contact area between the heat dissipation fins 21 and the air is large, heat can be quickly conducted, thereby reducing the temperature of the coolant and ensuring that the coolant can work stably for a long time.

[0031] The blowing assembly 3 includes a shell 31, which is fixedly connected to the outer shell 1. The shell 31 is internally rotatably connected with a fan blade 33, the axial end of the fan blade 33 is fixedly connected to the rotating shaft 6, the outer side of the shell 31 is fixedly connected with an air inlet plate 34, and the rear outer periphery of the shell 31 is fixedly connected with a rear air outlet 32. The fan blade 33 is driven by the rotating shaft 6 of the motor, and the rotation of the fan blade 33 drives the air flow around the heat sink 21 to circulate, thereby accelerating the heat dissipation effect of the coolant inside the spiral heat pipe 22.

[0032] The circulation box 7 includes a box body 71, which is fixedly connected to the outer shell 1. A liquid tank 72 and a circulation pump 73 are fixedly arranged inside the box body 71. The input end of the circulation pump 73 is connected to one side of the cooling chamber 11 through a first liquid pipe 74, and the output end of the circulation pump 73 is connected to the second liquid pipe 75 and one end of the spiral heat dissipation tube 22. One end of the liquid tank 72 is connected to the other end of the spiral heat dissipation tube 22 through a fourth liquid pipe 77, and the other end of the liquid tank 72 is connected to the other side of the cooling chamber 11 through a third liquid pipe 76. The circulation box 7 is set to drive the coolant to circulate. Specifically, the coolant in the cooling chamber 11 is pumped out to the spiral heat dissipation tube 22 for heat dissipation through the circulation pump 73, and then the coolant enters the liquid tank 72 from the other end of the spiral heat dissipation tube 22, and finally returns to the spiral heat dissipation tube 22 again through the third liquid pipe 76.

[0033] Both sides of the cooling cavity 11 are connected with a shunt cavity 12, which extends to the periphery of the stator 9. The shunt cavity 12 can increase the contact area between the coolant in the cooling jacket 10 and the cooling jacket 10, thereby improving the cooling effect of the cooling jacket 10.

[0034] Both sides of the lower end of the housing 1 are fixedly connected with mounting feet 4, and mounting holes 5 are provided at the bottom of the mounting feet 4. The mounting feet 4 with the mounting holes 5 are convenient for installing and fixing the motor.

[0035] The spiral heat dissipation tube 22 is made of a copper tube, and the heat dissipation fin 21 is made of an aluminum plate. The spiral heat dissipation tube 22 and the heat dissipation fin 21 have high heat conduction efficiency and strong heat dissipation effect.

[0036] Working principle: When in use, the cooling sleeve 10 is in contact with the stator 9, and the cooling cavity 11 is used to circulate the coolant, so that the coolant can perform efficient heat exchange and quickly cool the motor. The coolant after heat exchange is pumped out to the spiral heat dissipation tube 22 through the circulation pump 73 for heat dissipation. At the same time, the rotation of the fan blades 33 drives the air flow around the heat sink 21 to circulate, thereby accelerating the heat dissipation effect of the coolant inside the spiral heat dissipation tube 22. After that, the coolant enters the liquid tank 72 from the other end of the spiral heat dissipation tube 22, and finally returns to the spiral heat dissipation tube 22 through the third liquid pipe 76, thereby completing the circulation of the coolant.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
