Abstract

The name of the invention is a cool-air cooling system for a traction motor. The invention relates to a cooling system of a locomotive traction motor. The cooling system is adopted to mainly solve the problem that the cooling effect of a known locomotive traction motor which is cooled by adopting a ventilator to blow the air into the motor through an air inlet and a fan cover on the motor, discharging the air out of an air outlet on the motor and taking away heat in the motor so as to cooling the motor is not obvious. The cooling system provided by the invention comprises an air inlet, a fan cover and an air outlet, which are arranged on the motor, and is characterized in that an air duct is connected to the fan cover and the air duct is provided with an air cooler. According to the invention, the air cooler is adopted to send the air below minus 20 DEG C into the fan cover to be mixed with the air sent into the fan cover by the ventilator, and the mixed air is then sent into the motor so as to cool the motor. Thus, the cooling effect is obvious.

Description

Traction electric machine cold air cooling system
Technical field
The present invention relates to a kind of motor cold air cooling system, relate to specifically a kind of railway locomotive traction electric machine cold air cooling system.
Background technology
At present, the traction electric machine air cooling system of known railway locomotive as shown in Figure 1, during motor 7 work, the wind of ventilation blower is by air inlet 5, enter traction electric machine 7 inside through the fan housing 6 on motor 7, because the temperature (air themperature) of wind is lower than motor 7 temperature, motor 7 temperature are about 180 ℃, traction electric machine 7 is had to certain cooling effect, wind 8 discharges of the exhaust outlet from motor 7 by traction electric machine 7 inside simultaneously, take away amount of heat, makes motor 7 coolings; Its shortcoming is: adopt aforesaid way to carry out motor 7 cooling, the temperature of motor 7 also can only maintain higher temperature, and cooling-down effect is not obvious.
Summary of the invention
The objective of the invention 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.
Technical solution of the present invention is: traction electric machine cold air cooling system comprises air inlet, fan housing and the exhaust outlet be located on motor, it is characterized in that: be connected with an airduct on fan housing, airduct is provided with aerial cooler.
Airduct described in technical solution of the present invention is radially being connected on fan housing along fan housing.
The present invention adopts air refrigerator that the compressed air of air compressor machine part is made to cold air below-20 ℃ and sends into the wind that fan housing sends here with ventilation blower and mixed, and the temperature of the wind that ventilation blower sends here is reduced to below room temperature, thereby has improved cooling effect; Because this air refrigerator volume is little, lightweight, cost is low, efficiency is high, meets instructions for use; The present invention is simple in structure, easy to maintenance, and cooling effect is obvious.
The accompanying drawing explanation
Fig. 1 is the existing cooling system figure of traction electric machine.
Fig. 2 is structural representation of the present invention.
Embodiment:
As shown in Figure 2, the present invention includes the air inlet 5 and the fan housing 6 that are located on motor 7, and be located at the air outlet 8 on motor 7, side at fan housing 6, radially be connected with an airduct 1 along fan housing 6, be provided with an air refrigerator 2 on airduct 1, air refrigerator 2 can be purchased from the market, during work, the inlet end of airduct 1 is connected on air compressor machine, from air compressor machine, compressed air out 3 enters air refrigerator 2 through airducts 1, from air refrigerator 2, cold air 4 out is about-20 ℃, enter fan housing 6, the wind of now being sent here by ventilation blower is in air inlet 5 enters fan housing 6, the cold wind that enters fan housing 6 with airduct 1 is mixed, the temperature of fan housing 6 interior wind is reduced to below room temperature, because the temperature of the wind that enters traction electric machine 7 inside is low, therefore improved cooling effect, make motor 7 fast coolings, cold wind is discharged from exhaust outlet 8 by traction electric machine 7 inside simultaneously, take away amount of heat, locomotive traction motor 7 can be cooled to below 120 ℃.
