DETAILED DESCRIPTION

[0022] 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.

[0023] Specific examples are given below.

[0024] like Figure 1As shown, a generator cooling device described in an embodiment of the utility model comprises a base plate 1; a generator body 11 is fixedly connected to the top of the base plate 1; a water pipe 12 is connected to the side wall of the generator body 11; the end of the water pipe 12 is connected to a water outlet pipe 13; the end of the water outlet pipe 13 is connected to a water tank 14; the side wall of the water tank 14 is connected to a water pump 15; the side wall of the water pump 15 is connected to a water inlet pipe 16; the end of the water inlet pipe 16 is connected to the water pipe 12; the top of the water tank 14 is connected to a water injection pipe 17; when working, coolant is injected into the water tank 14 from the water injection pipe 17, then the water pump 15 is started to extract the coolant from the water tank 14, and then the coolant is sent from the water inlet pipe 16 into the water pipe 12. At this time, the water pipe 12 is in a spiral structure and will be connected to the outside of the generator body 11 The wall contact can absorb part of the dissipated heat, and the coolant that absorbs the heat enters the water outlet pipe 13 from the water pipe 12 and then enters the water tank 14 again. When the coolant is cooled in the water tank 14, the water pump 15 is started again for circulation. In this step, the coolant in the water tank 14 can be circulated by setting the water pump 15 to connect the water tank 14 and the water pipe 12, and the outside of the generator body 11 can be cooled. The coolant can be continuously cooled and reused through the circulation setting to reduce the situation where only the coolant inside the motor is used in contact with the heat source to generate temperature rise, resulting in weakened cooling and heat dissipation effects and damage to parts in the generator body 11. At the same time, the water pipe 12 is in spiral contact with the generator body 11, which can make the internal coolant stay on the surface of the generator body 11 longer to improve the cooling effect.

[0025] like Figure 2 As shown, a compressor 2 is fixedly connected to the top of the water tank 14; a refrigeration pipe 21 is fixedly connected to the side wall of the compressor 2; the refrigeration pipe 21 is located inside the water tank 14; when working, starting the compressor 2 for refrigeration can drive the refrigeration pipe 21 for refrigeration. At this time, the refrigeration pipe 21 is located inside the water tank 14. When the coolant circulates into the water tank 14, it will contact the refrigeration pipe 21. At this time, the refrigeration pipe 21 can cool the coolant. In this step, the coolant circulated into the water tank 14 can be cooled by setting the compressor 2 to connect the refrigeration pipe 21, so as to increase the speed at which the temperature of the coolant in the water tank 14 drops, so as to facilitate the use of the coolant for circulating cooling and heat dissipation again.

[0026] like Figure 2As shown, a slide groove 32 is provided on the top of the water tank 14; a dispersion plate 3 is provided on the inner wall of the water tank 14; a connecting plate 31 is fixedly connected to the top of the dispersion plate 3; during operation, when the coolant enters the water tank 14 from the water outlet pipe 13, it will pass through the dispersion plate 3. When passing through the dispersion plate 3, the holes on the dispersion plate 3 will disperse the coolant, and the dispersed coolant will be more evenly in contact with the refrigeration pipe 21. When the dispersion plate 3 needs to be maintained, the connecting plate 31 can be pulled up to remove the dispersion plate 3 and then reset after the maintenance is completed. In this step, the connecting plate 31 is set to connect the dispersion plate 3 to break up the coolant entering the water tank 14, so as to increase the contact surface between the coolant and the refrigeration pipe 21 when the coolant flows to the refrigeration pipe 21, so as to make the coolant contact with the refrigeration pipe 21 more evenly, so as to increase the speed at which the coolant temperature drops.

[0027] like Figure 1 and Figure 3 As shown, a bellows 4 is fixedly connected to the top of the base plate 1; a fan 41 is fixedly connected to the inner wall of the bellows 4; a plurality of ventilation holes 42 are provided on the side wall of the base plate 1; when working, starting the fan 41 to rotate can drive the airflow to blow from the ventilation holes 42 to the surface of the generator body 11, and when the airflow flows from the surface of the generator body 11, the generator body 11 can be blown to dissipate heat. In this step, the bellows 4 and the fan 41 are arranged to blow air to the generator body 11, and when the airflow passes through the surface of the generator body 11, part of the heat can be taken away, and the heat dissipation and cooling effect of the generator body 11 can be improved in combination with the water pipe 12.

[0028] like Figure 4 As shown, the side wall of the dispersion plate 3 is fixedly connected with a plurality of fixing frames 5; the middle part of the fixing frame 5 is rotatably connected with a fan blade 51; during operation, when the coolant flows out from the hole on the compressor 2, it will pass through the fan blade 51, and when the coolant flows, it can drive the fan blade 51 to rotate. At this time, the fan blade 51 can break up the coolant again, so that the coolant is dispersed into smaller liquid droplets. In this step, by setting the fan blade 51, the coolant can be dispersed for the second time when it flows out from the hole in the compressor 2, so that the contact range between the coolant and the refrigeration pipe 21 can be wider and more uniform, so as to increase the speed at which the coolant temperature drops.

[0029] like Figure 3 As shown, the side wall of the bellows 4 is provided with a filter 6; the filter 6 is detachably arranged; during operation, when the airflow enters the bellows 4, it will pass through the filter 6. At this time, the filter 6 will filter the incoming airflow. When maintenance is required, the filter 6 will be removed to clean the dust filtered off the surface and then install and reset it. In this step, the airflow entering the bellows 4 can be filtered by setting the filter 6 to reduce the dust and impurities mixed in the airflow entering the bellows 4 and accumulating to affect the rotation of the fan 41. At the same time, it can reduce the dust being blown to the surface of the generator body 11 and accumulating to affect the cooling and heat dissipation.

[0030] like Figure 4As shown, the side wall of the refrigeration pipe 21 is fixedly connected with a sealing gasket 7; during operation, when the dispersion plate 3 is put back into the water tank 14, the sealing gasket 7 on the side wall of the connecting plate 31 will contact the side wall of the slide groove 32. This step can increase the tightness of the connection between the connecting plate 31 and the slide groove 32 by setting the sealing gasket 7, so as to improve the sealing of the water tank 14 and reduce the leakage of the coolant in the water tank 14.

[0031] Working principle: inject coolant into the water tank 14 from the water injection pipe 17, then start the water pump 15 to extract the coolant from the water tank 14, and then send the coolant from the water inlet pipe 16 into the water pipe 12. At this time, the water pipe 12 has a spiral structure and will contact the outer wall of the generator body 11 to absorb part of the dissipated heat. The coolant that absorbs the heat enters the water outlet pipe 13 from the water pipe 12 and then enters the water tank 14 again. After the coolant is cooled in the water tank 14, start the water pump 15 to circulate again, and start the refrigeration of the compressor 2 to drive the refrigeration pipe 21 to refrigerate. At this time, the refrigeration pipe 21 is located inside the water tank 14. When the coolant circulates into the water tank 14, it will contact the refrigeration pipe 21. At this time, the refrigeration pipe 21 can cool the coolant. When the coolant enters the water tank 14 from the water outlet pipe 13, it will pass through the dispersion plate 3. When passing through the dispersion plate 3, the holes on the dispersion plate 3 will disperse the coolant. When the cooling liquid contacts the refrigeration pipe 21, it will be more even. When the dispersion plate 3 needs to be maintained, the connecting plate 31 can be pulled up to remove the dispersion plate 3 and then reset after the maintenance is completed. Starting the fan 41 to rotate can drive the airflow to blow from the ventilation hole 42 to the surface of the generator body 11. When the airflow flows from the surface of the generator body 11, the generator body 11 can be blown to dissipate heat. When the coolant flows out from the hole on the compressor 2, it will pass through the fan blades 51. When the coolant flows, it can drive the fan blades 51 to rotate. At this time, the fan blades 51 can break up the coolant again and disperse the coolant into smaller liquid droplets. When the airflow enters the bellows 4, it will pass through the filter screen 6. At this time, the filter screen 6 will filter the incoming airflow. When maintenance is needed, the filter screen 6 will be removed, the dust filtered off the surface will be cleaned up, and then it will be installed and reset. When the dispersion plate 3 is put back into the water tank 14, the sealing gasket 7 on the side wall of the connecting plate 31 will contact the side wall of the slide groove 32.
