[0003] To address the aforementioned issues, existing patents offer solutions. Most existing oil bath motor chambers typically immerse the rotor in cooling oil, relying on the rotor's rotation to throw the cooling oil onto the stator for cooling, or by setting up oil channels inside the housing to cool the stator. However, due to factors such as motor structure and oil flow characteristics, uneven cooling may occur.

[0004] Therefore, a heat dissipation structure for an oil bath motor chamber is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A heat dissipation structure for an oil bath motor chamber includes a motor body 1, a storage component 2 connected to the bottom of the motor body 1, a spray component 3 connected to the right side of the storage component 2, and a shield 4 fixedly connected to the surface of the motor body 1 for use with the spray component 3.

[0027] The spraying assembly 3 includes an oil pump body 301. The left side of the oil pump body 301 is connected to the storage assembly 2. The top of the oil pump body 301 is connected to an outlet pipe 302. The side of the outlet pipe 302 away from the oil pump body 301 is connected to a hollow pipe 303. The bottom of the hollow pipe 303 is connected to several spray heads 304. The hollow pipe 303 is bolted to the top of the motor body 1.

[0028] In this embodiment: by setting up a storage component 2, coolant can be stored; by setting up a spraying component 3, the coolant inside the storage component 2 can be sprayed into the motor body 1; by setting up a shield 4, the spraying component 3 can be shielded and protected; by setting up an oil pump body 301, an outlet pipe 302, a hollow pipe 303, and a spray head 304, the oil pump body 301 draws out the coolant from the storage tank 202 and sprays it evenly onto the surface of the motor body 1 through the outlet pipe 302, the hollow pipe 303, and the spray head 304; the shield 4 can prevent coolant splashing, so that the coolant can cool the motor body 1 more concentratedly, solving the problem of uneven cooling caused by the structure of the motor body 1 and the flow characteristics of the oil in the prior art, improving the heat dissipation efficiency of the motor body 1, ensuring that the motor body 1 works stably within a reasonable temperature range, and extending the service life of the motor body 1.

[0029] Specifically, such as Figure 3 As shown, the storage component 2 includes a first solenoid valve 201, the bottom of which is connected to a storage box 202, and the right side of the storage box 202 is connected to a second solenoid valve 203.

[0030] Specifically, such as Figure 3 As shown, a pull-out hole 204 is provided on the left side of the storage box 202. A frame 205 is snapped into the inner wall of the pull-out hole 204, and a filter screen 206 is fixedly connected inside the frame 205.

[0031] Specifically, such as Figure 3 As shown, a sealing block 207 is snapped into the inside of the second solenoid valve 203, and the sealing block 207 is made of silicone.

[0032] In this embodiment: by setting a first solenoid valve 201, a storage tank 202, and a second solenoid valve 203, the first solenoid valve 201 can control the flow of cooling oil from the motor body 1 into the storage tank 202, and the second solenoid valve 203 can control the flow of cooling oil from the storage tank 202 to the spray assembly 3, which facilitates precise control of the cooling oil circulation process. By setting a pull-out hole 204, a frame 205, and a filter screen 206, the frame 205 with a filter screen 206 is snapped into the pull-out hole 204 on the left side of the storage tank 202. During the cooling oil circulation process, the filter screen 206 can intercept impurities in the cooling oil, preventing impurities from entering the spray assembly 3 or the motor body 1, avoiding blockage of pipes or wear on the internal parts of the motor body 1. By setting a sealing block 207, the sealing effect of the second solenoid valve 203 can be increased.

[0033] Specifically, such as Figure 4 As shown, a corrosion-resistant sleeve 5 is fixedly connected to the inner wall of the storage box 202, and a magnetic stick 6 is fixedly connected to the bottom of the inner wall of the storage box 202.

[0034] Specifically, such as Figure 2 As shown, a sealing plate 7 is fixedly connected to the top of the motor body 1, and a sealing groove 8 for use with the sealing plate 7 is opened at the bottom of the hollow tube 303.

[0035] In this embodiment: by setting the corrosion-resistant sleeve 5 and the magnetic rod 6, the corrosion-resistant sleeve 5 on the inner wall of the storage tank 202 can prevent the cooling oil from corroding the storage tank 202 and extend the service life of the storage tank 202. The magnetic rod 6 can adsorb metal impurities in the cooling oil, further purify the cooling oil, and reduce the damage of metal impurities to the internal parts of the motor body 1. By setting the sealing plate 7 and the sealing groove 8, the sealing plate 7 on the top of the motor body 1 and the sealing groove 8 at the bottom of the hollow tube 303 are used together to prevent the cooling oil from leaking from the top of the motor body 1 during the spraying process, ensuring that the cooling oil can be used entirely for cooling the motor body 1 and improving the cooling effect.

[0036] Specifically, such as Figure 5 As shown, a protective cover 9 is bolted to the right side of the storage box 202, and a ventilation hole 10 is provided on the rear side of the protective cover 9.

[0037] Specifically, such as Figure 5 As shown, a protective sleeve 11 is fitted on the surface of the protective cover 9. A square hole 12 is provided on the rear side of the protective sleeve 11 to cooperate with the ventilation hole 10. A dust interception net 13 is fixedly connected to the inner wall of the square hole 12.

[0038] In this embodiment: by setting a protective cover 9 and a ventilation hole 10, the protective cover 9 on the right side of the storage box 202 can protect the spraying component 3 and prevent external objects from damaging it. The ventilation hole 10 can promote the circulation of air inside the protective cover 9, help dissipate heat from components such as the oil pump body 301, and avoid affecting its normal operation due to overheating. By setting a protective sleeve 11, a square hole 12 and a dust interception net 13, the protective sleeve 11 on the surface of the protective cover 9 has a square hole 12 that matches the ventilation hole 10. The dust interception net 13 inside the square hole 12 can block external dust from entering the interior of the protective cover 9 through the ventilation hole 10, preventing dust from accumulating on the spraying component 3 and affecting its heat dissipation and normal operation, while ensuring the ventilation effect of the ventilation hole 10.

[0039] Working principle: The motor body 1 generates heat during operation. At this time, the first solenoid valve 201 opens, and cooling oil flows from the bottom of the motor body 1 into the storage tank 202 of the storage component 2. The filter screen 206 in the pull-out hole 204 on the left side of the storage tank 202 intercepts impurities in the cooling oil. The corrosion-resistant sleeve 5 on the inner wall of the storage tank 202 prevents the cooling oil from corroding the tank. The magnetic rod 6 at the bottom adsorbs metal impurities in the cooling oil to purify the oil. Then, the second solenoid valve 203 opens, and the oil pump body 301 draws the cooling oil from the storage tank 202 and delivers it to the hollow tube 303 through the outlet pipe 302. Then, it is evenly sprayed onto the motor body 1 through several spray nozzles 304 at the bottom of the hollow tube 303. The surface of the motor is cooled by a shield 4 to prevent the cooling oil from splashing and to concentrate the cooling. The sealing plate 7 on the top of the motor body 1 cooperates with the sealing groove 8 at the bottom of the hollow tube 303 to prevent the cooling oil from leaking. The protective cover 9 on the outside of the spray assembly 3 protects it. The ventilation hole 10 on the back of the protective cover 9 promotes air circulation and helps the oil pump body 301 and other components dissipate heat. The square hole 12 on the protective sleeve 11 on the surface of the protective cover 9 corresponds to the ventilation hole 10. The dust interception net 13 inside the hole prevents dust from entering. The cooled oil may flow back to the storage tank 202. This cycle achieves effective heat dissipation of the motor body 1 and solves the problem of uneven cooling in the prior art.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
