Abstract

The utility model relates to an air-to-air cooling motor cooling structure, which comprises an air-to-air cooler and an air-introducing device, the air-introducing device includes an air-introducing pipe, and the air-inlet end of the air-introducing pipe and the air-inlet end of the air-to-air cooler Connected, the air outlet end of the air duct is placed at the rear end cover of the motor. Because the wind with lower temperature is led to the rear end cover through the air induction device, the rear end cover is locally cooled, the temperature of the end cover bearing there is reduced, and the service life of the bearing is improved.

Description

An air-to-air cooling motor cooling structure

technical field

The utility model relates to the field of motors, in particular to an air-to-air cooling motor cooling structure.

Background technique

At present, air-to-air cooling motors are equipped with an air-to-air cooler above the motor frame. The cooler mainly cools the inside of the motor winding. In order not to affect other parts of the equipment, the cooler generally enters the air from the front of the motor and exits from the rear. . Due to the structure of the motor, the temperature at the rear end of the motor is higher than the temperature at the front end of the motor, and it is difficult to dissipate heat at the rear end of the motor. As a result, the temperature of the rear end bearing is high when the motor is running, which affects the service life of the bearing, resulting in unstable operation of the motor.

Utility model content

The purpose of this utility model is to overcome the above defects and provide a cooling structure for an air-to-air cooling motor that reduces the temperature of the rear end cover bearing.

The technical scheme of the present invention is an air-to-air cooling motor cooling structure, which includes an air-to-air cooler, and also includes an air-inducing device, the air-introducing device includes an air-introducing pipe, and the air-inlet end of the air-introducing pipe is connected to the air-to-air cooling The air inlet end of the device is connected end to end, and the air outlet end of the air induction pipe is placed at the rear end cover of the motor.

In order to increase the amount of air intake, the air induction device also includes an air induction cover, which is arranged at the end of the air intake end of the air induction pipe.

In order to further increase the air volume, air induction devices are provided on both sides of the air-to-air cooler.

The air induction device is arranged symmetrically along both sides of the air-to-air cooler.

The technical effect of the utility model is that the lower-temperature wind is led to the rear end cover through the air-inducing device, thereby locally cooling the rear end cover, so that the temperature of the end cover bearing at this place is reduced, and the The service life of the bearing.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

An air-to-air cooling motor cooling structure, which includes an air-to-air cooler 4 and an air-introducing device. 2. It is fixed on both sides of the air-to-air cooler 4 through the fixing device 3. The air inlet end of the air-induction pipe 2 is provided with an air-induction hood 1. The air-induction hood 1 is connected to the front end of the air-to-air cooler 4. The air outlet of the air-induction pipe 2 The end is placed on the top of the motor 5 rear end cover 6.

The technical effect of the utility model is that due to the low temperature wind at the front end of the air-to-air cooler 4 is led to the rear end cover 6 through the air-inducing device, thereby locally cooling the rear end cover 6, so that the end cover at this place The temperature of the bearing is reduced, which improves the service life of the bearing of the motor 5 .

The above is only an implementation manner of the present utility model, a preferred example. The scope of protection claimed in the utility model application is not limited to the implementation mode. All technical solutions equivalent to this embodiment belong to the protection scope of the present utility model.
