[0021] A cooler housing 6 is arranged on a component to be cooled 10;

[0022] A centrifugal fan 1 is arranged on one side of a cooler housing 6, and a fan motor 2 is arranged on the cooler housing 6 to drive the centrifugal fan 1 to rotate;

[0023] The cooler water core 3 is arranged on the cooler housing 6, and the cooler housing 6 is divided into an air inlet chamber and an air outlet chamber. The cooler water core 3 is provided with a water inlet flange 4 and a water outlet flange 5. The centrifugal fan 1 is located in the air inlet chamber. The air inlet chamber is provided with a cooler air inlet device 7, and the air outlet chamber is provided with a cooler air outlet device 8.

[0024] The air inlet device 9 is arranged on the top of the component to be cooled 10, and communicates the air inlet chamber with the inner space of the component to be cooled 10;

[0025] And a hot air outlet 11 is arranged at the top of the component to be cooled 10 and communicates with the air outlet chamber and the inner space of the component to be cooled 10.

[0026] Embodiment 2, as Figure 1-Figure 4 As shown, the present invention proposes a cooling structure of an IC86W and IC01 dual-cooling motor. Compared with the first embodiment, this embodiment introduces the specific details of the structure in detail.

[0027] Two cooler air inlet devices 7 are provided, and the two cooler air inlet devices 7 are respectively provided on the opposite sides of the cooler shell 6. Two cooler air outlet devices 8 are provided, and the two cooler air inlet devices 7, the centrifugal fan 1 and the cooler air outlet device 8 are respectively located on the four vertical sides of the cooler shell 6.

[0028] The water inlet flange 4 and the water outlet flange 5 are respectively located on the opposite side surfaces of the cooler water core 3 and are both located on the outside of the cooler shell 6. Two water inlet flanges 4 and two water outlet flanges 5 are provided. The water inlet flange 4 and the water outlet flange 5 are connected to the water supply system. The water inlet flange 4 introduces cooling water into the cooler water core 3, and the water outlet flange 5 discharges the water in the cooler water core 3, and then the water supply system realizes circulation and cooling.

[0029] The air inlet device 9 includes a mounting plate and a plurality of ventilation rings arranged on the mounting plate. The ventilation rings are arranged vertically. The mounting plate is arranged on the top of the component to be cooled 10. A plurality of air inlet devices 9 are arranged.

[0030] A plurality of centrifugal fans 1 and a plurality of blower motors 2 are provided. In the present invention, a plurality of centrifugal fans 1 and a plurality of blower motors 2 are provided.

[0031] When the external circulation air path is in the heat dissipation state, the external air enters the air inlet chamber through the cooler air inlet device 7, then enters the component to be cooled 10 through the air inlet device 9, and is discharged into the air outlet chamber through the hot air outlet 11, and finally discharged from the cooler air outlet device 8 on the air outlet chamber.

[0032] In summary, when the present invention is in use, when water is supplied at the water inlet flange 4, the centrifugal fan 1, the fan motor 2, the cooler water core 3, the water inlet flange 4, the water outlet flange 5, the cooler housing 6, and the component to be cooled 10 are put into use to form an IC86W air-water cooling structure. At this time, the fan motor 2 is powered, driving the centrifugal fan 1 to rotate to form a pressure head, forcing the air in the cooler system and the component to be cooled 10 to flow axially and radially in the motor air duct, taking away the heat generated when the motor is running, and turning into hot air. The hot air enters the cooler housing 6 from the hot air outlet 11, and the hot air is cooled by the circulating water in the cooler water core 3 to become cold air. The cold air is then pressed into the cooler housing 6 from the air inlet device 9 on the component to be cooled 10 by the centrifugal fan 1, thereby forming an internal circulation air path. At this time, the cooling water that cools the hot air returns to the water supply system after passing through the water outlet flange 5. At this time, the motor does not need to exchange with the outside air, and the motor can run for a long time with 100% rated load.

[0033] When the water supply system fails or lacks water, and there is no water supply at the water inlet flange 4, the centrifugal fan 1, the fan motor 2, the cooler housing 6, the cooler air inlet device 7, the cooler air outlet device 8, the air inlet device 9, and the component to be cooled 10 are put into use to form an IC01 air-to-air cooling structure. At this time, the cooler air inlet device 7, the cooler air outlet device 8, and the air inlet device 9 are turned on, and the fan motor 2 is powered to drive the centrifugal fan 1 to rotate to form a pressure head, suck in air from the atmosphere, and force the air in the cooler system and the component to be cooled 10 to flow axially and radially in the motor air duct, taking away the heat generated when the motor is running, turning into hot air, and entering the cooler housing 6 from the hot air outlet 11 of the component to be cooled 10, and the hot air is discharged from the cooler air outlet device 8 to form an external circulation air path. At this time, the motor cooling method: IC01, the protection level: IP23, the motor can run for a long time with 85% rated load. Under this working condition, the cooler water core 3, the water inlet flange 4, and the water outlet flange 5 can maintain the original IC86W connection method. When the cooling water supply of the motor is restored, the cooler air inlet device 7, the cooler air outlet device 8 and the air inlet device 9 can be blocked with the cover plate again, and the motor will automatically switch to the IC86W cooling mode. The motor does not need to be shut down during the switching between the two cooling modes.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
