Description

Technical Field

[0001] The utility model relates to the technical field of motor cooling devices, in particular to a motor cooling mechanism. Background Art

[0002] At present, low-voltage motors are widely used in high-temperature environments. Almost all motors are cooled by air. For motors with larger numbers of stages, the speed and the motor cooling fan blades are important factors affecting the heat dissipation of the motor. If the temperature of the motor is too high, it will affect the life of the motor, increase the overall temperature of the surrounding environment, and indirectly affect other equipment. Therefore, in order to effectively improve the heat dissipation capacity of the motor, a structure that can cool the motor in high-temperature places is needed. Summary of the invention

[0003] In order to solve one or some technical problems existing in the prior art, the purpose of the present application is to provide a motor cooling mechanism, which can effectively dissipate the temperature of the motor, is easy to disassemble, and has higher practicality.

[0004] In order to solve the above existing technical problems, this application adopts the following technical solutions:

[0005] A motor cooling mechanism comprises a motor stator housing, a stator end cover, a motor base, a motor oil seal and a motor rotor, wherein a motor cooling disk is arranged on the outer side of the stator end cover, a fixed mounting part is arranged between the motor cooling disk and the stator end cover, a water inlet interface and a water outlet interface are arranged on the motor cooling disk, cooling medium flows in the motor cooling disk through the water inlet interface and the water outlet interface, and the stator end cover is cooled by the motor cooling disk.

[0006] Preferably, the motor cooling plate is formed by winding a copper tube, and the outer surface of the motor cooling plate is treated with anti-corrosion.

[0007] Preferably, the fixed mounting member comprises three clamps arranged around the motor cooling plate, the clamps are penetrated by through holes, and the clamps are connected and fixed to the stator end cover mounting screws through the through holes.

[0008] Preferably, a U-shaped clamping groove is provided at the bottom of the clamping hoop, and the clamping hoop is detachably clamped on the motor cooling plate through the clamping groove.

[0009] Preferably, a protective sleeve is provided on the outside of the motor cooling plate.

[0010] Preferably, both the water inlet interface and the water outlet interface are provided with internal threads.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The motor cooling plate is fitted with the outer side of the stator end cover through a fixed mounting part. At the same time, the motor cooling plate is connected to the external cooling medium through the water inlet interface and the water outlet interface. When the motor needs to be cooled, the cooling medium flows in from the water inlet interface. The cooling medium cools the stator end cover when passing through the motor cooling plate, thereby achieving the cooling of the entire motor by cooling the stator end cover. The cooling medium then flows out from the water outlet interface for cooling, and then is recycled. Through the circulating flow of the cooling medium, the motor cooling plate cools the stator end cover, effectively solving the problem of shortened life of the motor due to excessive temperature in a high temperature environment and increased overall temperature of the surrounding environment.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

[0022] like Figure 1 As shown, a motor cooling mechanism includes a motor stator housing 1, a stator end cover 2, a motor base 3, a motor oil seal 4 and a motor rotor 5. A motor cooling disk 7 is provided on the outer side of the stator end cover 2, a fixed mounting part 9 is provided between the motor cooling disk 7 and the stator end cover 2, and a water inlet interface 8 and a water outlet interface 6 are provided on the motor cooling disk 7. Cooling medium flows in the motor cooling disk 7 through the water inlet interface 8 and the water outlet interface 6, and the stator end cover 2 is cooled by the motor cooling disk 7.

[0023] In the actual assembly process, the motor itself is composed of a stator housing, a stator end cover 2, a motor base 3, a motor oil seal 4 and a motor rotor 5. During operation, when the motor rotor 5 rotates at a relatively fast speed, it is easy to cause the stator end cover 2 to generate high temperature. Therefore, a motor cooling plate 7 is installed on the outside of the stator end cover 2 through a fixed mounting member 9. The motor cooling plate 7 is fitted with the outer side of the stator end cover 2 through the fixed mounting member 9. At the same time, the motor cooling plate 7 is connected to the external cooling medium through the water inlet interface 8 and the water outlet interface 6. When the motor needs to be cooled, the cooling medium flows in from the water inlet interface 8, and the cooling medium flows in from the water inlet interface 8. When the cooling medium passes through the motor cooling disk 7, the stator end cover 2 is cooled, so that the temperature of the entire motor is reduced by cooling the stator end cover 2. The cooling medium then flows out from the water outlet interface 6 for cooling, and then is recycled. Through the circulating flow of the cooling medium, the motor cooling disk 7 cools the stator end cover 2, which effectively solves the problem of shortened life of the motor due to excessive temperature in a high temperature environment and increased overall temperature of the surrounding environment. In particular, when the cooling medium is water, it only needs to be connected in series with the water tank through a water pipe, and water circulation cooling can be achieved through a water pump, which has lower production costs and better cooling effects.

[0024] Further improvement is as follows: Figure 2 As shown, the motor cooling plate 7 is formed by winding a copper tube, and the outer surface of the motor cooling plate 7 is treated with anti-corrosion.

[0025] The motor cooling disk 7 can have a longer service life and a better cooling effect, and the heat absorption of the stator end cover 2 can be faster.

[0026] As a further improvement, the fixed mounting member 9 includes three clamps 10 arranged around the motor cooling plate 7 , the clamps 10 are penetrated by through holes 11 , and the clamps 10 are connected and fixed to the stator end cover 2 by mounting screws through the through holes 11 .

[0027] At present, the general motor stator housing 1 and the stator end cover 2 are connected and fixed by three bolts. Therefore, the fixed installation part 9 is composed of three clamps 10, and the positions of the three clamps 10 correspond to the positions of the bolt holes of the stator end cover 2. When the motor cooling plate 7 and the stator end cover 2 are installed and fitted, they can be directly connected to the through hole 11 by installing bolts to fix them, thereby avoiding the problem of opening holes on the motor, especially when the through hole 11 adopts a long strip hole, the installation applicability is wider. The installation of the clamp 10 facilitates the daily maintenance in the later stage, and can also protect the motor.

[0028] Further improvement is as follows: Figure 4 and Figure 5 As shown, a U-shaped clamping groove 12 is provided at the bottom of the clamping hoop 10 , and the clamping hoop 10 is detachably clamped on the motor cooling plate 7 through the clamping groove 12 .

[0029] The clamp 10 and the motor cooling plate 7 are generally fixed by welding. However, in order to avoid the problem that the position of the through hole 11 cannot correspond to the connecting screw, a detachable connection is adopted between the clamp 10 and the motor cooling plate 7, wherein a U-shaped groove 12 is provided at the bottom of the clamp 10. The bottom of the clamp 10 is detachably mounted on the copper tube of the outer ring of the motor cooling plate 7 through the U-shaped groove 12, so that the position of the clamp 10 can be easily adjusted, thereby solving the problem that the position of the through hole 11 cannot match the connecting screw.

[0030] Further improvement is as follows: Figure 3 As shown, a protective sleeve 13 is disposed outside the motor cooling plate 7 .

[0031] The protective sleeve 13 is installed on the outside of the motor cooling plate 7. The protective sleeve 13 can cover the outside of the motor cooling plate 7, thereby preventing the motor cooling plate 7 from being deformed by external impact. The protective sleeve 13 is a rubber sleeve, which is more convenient for disassembly and assembly.

[0032] As a further improvement, both the water inlet interface 8 and the water outlet interface 6 are provided with internal threads, so that after the external leveling pipe is fixed, the sealing performance is better.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
