Abstract
The utility model provides a cool air cooling system for a traction motor, relates to a cool air cooling system for a locomotive traction motor, and aims to mainly solve the problem that the known cooling of the railway traction motor adopts a ventilator to put air into the motor through an air inlet and a fan cover of the motor, and then the air is discharged from an air vent of the motor, so as to take away the heat in the motor to cool down the motor, but the cooling effect is not obvious. The cooling system comprises the air inlet, the fan cover and the air vent, which are arranged on the motor, and is characterized in that an air duct is connected with the fan cover, and an air-cooler is arranged on the air duct. According to the utility model, the air-cooler is adopted to put the air below -20 DEG C into the fan cover to mix with the air put into the fan cover by the ventilator, and then the mixed cool air is put into the motor to cool down the motor, so that the cooling effect is obvious.
Description
Technical field
The utility model relates to a kind of motor cold air cooling system, relates to a kind of railway locomotive traction electric machine cold air cooling system specifically.
Background technology
At present, the traction electric machine air cooling system of known railway locomotive is as shown in Figure 1, and the wind of ventilation blower is through air inlet 5 during motor 7 work; Get into traction electric machine 7 inside through the fan housing on the motor 76, because the temperature (air themperature) of wind is lower than motor 7 temperature, motor 7 temperature are about 180 ℃; Traction electric machine 7 there is certain cooling effect; Wind is discharged from the exhaust outlet 8 on the motor 7 through traction electric machine 7 inside simultaneously, takes away a large amount of heats, makes motor 7 coolings; Its shortcoming is: adopt aforesaid way that motor 7 is cooled off, the temperature of motor 7 also can only maintain higher temperature, and cooling-down effect is not obvious.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, and provide a kind of easy and simple to handle, obviously reduce the cooling system of motor temperature.
The technical solution of the utility model is: traction electric machine cold air cooling system comprises air inlet, fan housing and the exhaust outlet that is located on the motor, it is characterized in that: on fan housing, be connected with an airduct, airduct is provided with aerial cooler.
Airduct described in the technical solution of the utility model is radially being connected on the fan housing along fan housing.
The utility model adopts air refrigerator that the compressed air of air compressor machine part is processed cold air below-20 ℃ and sends into fan housing and mix with the wind that ventilation blower is sent here, the temperature of the wind that ventilation blower sends here is reduced to below the room temperature, thereby has improved cooling effect; Because this air refrigerator volume is little, in light weight, cost is low, efficient is high, meets instructions for use; The utility model is simple in structure, and is easy to maintenance, and cooling effect is obvious.
Description of drawings
Fig. 1 is the existing cooling system figure of traction electric machine.
Fig. 2 is the structural representation of the utility model.
Embodiment:
As shown in Figure 2, the utility model comprises the air inlet 5 and fan housing 6 that is located on the motor 7, and is located at the air outlet 8 on the motor 7; In the side of fan housing 6, along fan housing 6 radially be connected with an airduct 1, on airduct 1, be provided with an air refrigerator 2; Air refrigerator 2 can be purchased from market, and during work, the inlet end of airduct 1 is connected on the air compressor machine; The compressed air 3 that comes out from air compressor machine gets into air refrigerator 2 through airduct 1, and the cold air 4 that comes out from air refrigerator 2 is about-20 ℃, gets into fan housing 6; The wind that sent by ventilation blower this moment gets in the fan housing 6 through air inlet 5, and the cold wind that gets into fan housing 6 with airduct 1 mixes, and the temperature of wind in the fan housing 6 is reduced to below the room temperature; Because the temperature of the wind of entering traction electric machine 7 inside is low, has therefore improved cooling effect, makes motor 7 fast coolings; Cold wind is discharged from exhaust outlet 8 through traction electric machine 7 inside simultaneously, takes away a large amount of heats, and locomotive traction motor 7 can be cooled to below 120 ℃.
