Description

Technical Field

[0001] The utility model relates to the technical field of water-cooling and heat dissipation devices for motor casings, in particular to a water-cooling and heat dissipation device for motor casings. Background Art

[0002] The motor casing water cooling device is a device specially designed to reduce the operating temperature of the motor. It uses water cooling technology to effectively discharge the heat generated inside the motor to ensure stable operation of the motor and extend its service life.

[0003] When a water cooling device is installed on the casing of a rail transit traction motor for heat dissipation, the existing water cooling device is usually spirally wound around the outer surface of the motor casing through a water pipe, and then the two ends are respectively installed at the inlet and outlet of the cooling water tank for water circulation cooling treatment. In this way, water cooling heat dissipation treatment is easy to occur. The water inside the water pipe near the outlet of the cooling water tank is cold water that has just flowed out of the cooling water tank, so the overall temperature will be lower and the heat dissipation speed will be faster. The water inside the water pipe far away from the cooling water tank is water that has undergone heat exchange before, so the heat dissipation speed will be slower, resulting in uneven heat dissipation of the motor casing, which can easily cause uneven distribution of thermal stress in the internal structure of the motor, resulting in increased motor vibration and noise, affecting the overall performance of the equipment.

[0006] The effect achieved by the above components is: when the water cooling device is installed on the casing of the rail transit traction motor for heat dissipation treatment, the water cooling device is started to cool the water and then flow into the first square tube, and then evenly dispersed and diverted into several diversion cooling tubes, so that the water temperature inside each diversion cooling tube is consistent, and the motor casing body is evenly cooled and dissipated, avoiding the occurrence of uneven thermal stress distribution in the internal structure of the motor, reducing the vibration and noise of the motor, and improving the overall performance of the equipment.

At this time, the semiconductor refrigeration plates 210 on both sides will cool the surface of the cooling water tank 24, so that it can exchange heat with the water inside to reduce the temperature of the water. Then start the water pump 25 to pump the water in the cooling water tank 24 into the water outlet pipe 26, so that it enters the interior of the first square tube 21, and then evenly disperses and guides it into the interior of several guide cooling pipes 23, so that the guide water The outer surface temperature of the cooling pipe 23 is lowered to exchange heat with the surface of the motor casing body 1 to achieve the effect of cooling and dissipating heat.

The inner wall of the cooling water tank 24 is symmetrically fixed with a plurality of guide plates 212, and the plurality of guide plates 212 are staggered. By providing the guide plates 212, the flow trajectory of the cooling water in the cooling water tank 24 can be extended, and the retention time of the water in the cooling water tank 24 can be increased, so that it can fully contact the inner wall of the cooling water tank 24 after being cooled by the semiconductor refrigeration plate 210, so that the circulating water can be quickly cooled down.

[0031] Reference Figure 2 As shown, this embodiment discloses that a detachable device 3 is provided between one side of the first square tube 21 and the second square tube 22 and the outer surface of the motor casing body 1. The detachable device 3 includes two T-slot blocks 33 and two bolts 35. One side of the two T-slot blocks 33 is fixedly connected to one side of the first square tube 21 and the second square tube 22 respectively. Second threaded holes 34 are symmetrically opened on both sides of the inner wall of the T-slot block 33. The outer surface of the motor casing body 1 is symmetrically fixedly connected with a T-block 31, which is inserted into the inner wall of the T-slot block 33. A first threaded hole 32 is symmetrically opened on one side of the T-block 31, and one end of the bolt 35 is screwed into the inner wall of the first threaded hole 32 and the second threaded hole 34.

[0033] Working principle: when the water cooling device 2 is installed on the casing of the rail transit traction motor for heat dissipation treatment, in the process of using the motor casing body 1 after installation, first inject cooling water into the cooling water tank 24 from the inlet of the cooling water tank 24, and then screw on the box cover 28 to seal the cooling water tank 24.

When it is injected to a certain capacity, the internal pressure increases, which will cause the circular plates 294 in the several guide cooling tubes 23 to move downward from the side of the circular block 291, driving the telescopic rod 293 and the spring 295 to move upward. The bracket 292 and the circular plate 294 are stretched open to leave a certain through hole between the circular plate 294 and the annular block 291, so that the cooling water retained in the first square tube 21 can be evenly guided into the guide cooling tube 23, so that the outer surface temperature of the guide cooling tube 23 is reduced to exchange heat with the surface of the motor casing body 1 to achieve the effect of cooling and heat dissipation. Since the water temperature injected into each guide cooling tube 23 is consistent at the same time, the motor casing body 1 can be evenly cooled and heat-dissipated, avoiding the occurrence of uneven thermal stress distribution in the internal structure of the motor, reducing the vibration and noise of the motor, and improving the overall performance of the equipment. Finally, the water in several guide cooling tubes 23 will flow into the second square tube 22 and gather, and finally return to the cooling water tank 24 through the water inlet pipe 27 for circulation cooling treatment.

[0034] When the guide cooling pipe 23 or the cooling water tank 24 is damaged and needs to be replaced, the bolt 35 can be manually screwed out from the first threaded hole 32 and the second threaded hole 34, and then the first square tube 21 and the second square tube 22 can be pulled to one end to a certain position, so that the inner wall of the T-shaped slot block 33 on one side is moved out from the outer surface of the T-shaped block 31, driving several guide cooling pipes 23 to be moved away from the outer surface of the motor casing body 1, so that the guide cooling pipe 23 and the cooling water tank 24 can be removed from the outer surface of the motor casing body 1, making it easier to replace them.
