Abstract
The utility model relates to a windmill generator cooler which comprises an air inlet arranged on the outer end face of a slip ring chamber, an air outlet arranged on the bottom of the slip ring chamber, and a cooler arranged in the slip ring chamber, wherein the cooler is arranged on a motor shaft and is adjacent to a non-driven end bearing device, and the air outlet is positioned below the cooler. The utility model solves the technical problems of poor cooling effect and difficulty in cleaning carbon powder generated by carbon brush abrasion in the existing slip ring chamber cooling mode. The utility model can well control the temperature rise of the bearing, prolongs the service life of the bearing, and enhances the reliability and stability of the motor.
Description
Technical field
The utility model relates to a kind of motor cooling device, relates in particular to a kind of aerogenerator cooling unit.
Background technology
Existing wind-driven generator slip ring cooling is to lean on slip ring chamber interior and extraneous air exchange to realize the cooling to slip ring; This type of cooling is not fine for taking away the heat cooling effect that produces because of high speed rotary grinding between slip ring and the carbon brush, and long-play has very big influence to the properties of product of motor.And the carbon dust that the carbon brush wearing and tearing produce is not easy cleaning.
Summary of the invention
The technical problem poor for the cooling effect that solves the existing slip ring chamber type of cooling and carbon dust that the carbon brush wearing and tearing produce is not easy to clear up, the utility model provides a kind of aerogenerator cooling unit.
The technical solution of the utility model:
A kind of aerogenerator cooling unit; Its special character is: comprise the cooling device air inlet that is arranged on the outdoor end face of slip ring, be arranged on the cooling device air outlet of bottom, slip ring chamber and be arranged on the indoor cooling device of slip ring; Said cooling device is arranged on the motor shaft and near the non-driven-end bearing device of wind-driven generator, said air outlet is positioned at the below of cooling device.
Above-mentioned cooling device is a centrifugal fan, and the air inlet of said centrifugal fan is towards the cooling device air inlet.
Above-mentioned cooling device air inlet is netted cover plate.
The position of above-mentioned cooling device air inlet is corresponding with the slip ring position.
The advantage that the utility model had:
1, centrifugal fan can pass through the cold air in the external world the indoor cooling slip ring system of netted cover plate suction slip ring of the outdoor end face of slip ring after rotating, and directly blows on the bearing end cover, and the cold wind of inspiration is taken away the heat on the bearing end cover; Simultaneously owing to increased external fan; Make electric motor end cap ambient air flow faster, the heat on the end cap of band radiating ribs is pulled away easily, thus better controlled the temperature rise of bearing; Improve the useful life of bearing, also improved the reliability and stability of motor.
2, centrifugal fan can axially be inhaled the carbon dust of carbon brush wearing and tearing and come, and throws out from circumference then, and the air outlet under the slip ring chamber flows out the slip ring chamber at last, collects through the carbon dust filter again.
Description of drawings
Fig. 1 is the sketch map as a result of the utility model.
Wherein Reference numeral is: 1-non-driven-end bearing device, 2-slip ring chamber, the netted cover plate of 3-, 4-cooling device air outlet, 5-axle, 6-centrifugal fan.
Embodiment
A kind of aerogenerator cooling unit; Comprise the cooling device air inlet that is arranged on 2 outer faces, slip ring chamber, be arranged on the cooling device air outlet 4 of bottom, slip ring chamber and be arranged on the cooling device in the slip ring chamber 2; Cooling device is arranged on the motor shaft 5 and near the non-driven-end bearing device 1 of wind-driven generator, air outlet is positioned at the below of cooling device.
Cooling device is a centrifugal fan 6, and the air inlet of centrifugal fan is towards the cooling device air inlet.
The cooling device air inlet is netted cover plate.
The position of cooling device air inlet is corresponding with the slip ring position.
This centrifugal fan is used on the general-purpose machine, is assemblied in the position between non-driven-end bearing device and the slip ring system, can play following effect:
1. centrifugal fan can pass through the cold air of motor outside the indoor cooling slip ring system of netted cover plate suction slip ring of rear end, slip ring chamber after rotating, and can also cool off rear end bearing;
2. centrifugal fan can axially be inhaled the carbon dust of carbon brush wearing and tearing and come, and throws out from circumference then, and the air outlet under the slip ring chamber flows out the slip ring chamber at last, collects through the carbon dust filter again.
