Abstract
The invention relates to a water cooler for cooling hot wind of a double-fed wind driven generator. A cooling box is installed above a generator box, a wind outlet is arranged at the middle of the top of the generator box, wind return holes are formed on two sides of the wind outlet at the top of the generator box, a cooler comprising four side plates and a plurality of cooling tubes is arranged in the cooling box, the four side plates are fixed at the top of the generator box through bolts, the cooling tubes are positioned above the wind outlet and communicated with the generator box through the wind outlet, the wind outlet is arranged below the plurality of cooling tubes between two of the side plates, and a water inlet tube and a water outlet tube which are communicated with the cooling tubes are arranged on either of the two sides plates. According to the invention, the cooler is horizontally installed in the cooling box and directly connected with the wind outlet of the generator box, and hot wind in the generator box leave away from the cooling box fast, so that the fast heat exchanging and cooling can be realized. The water cooler provided by the invention has the advantages of simple and compact structure, small volume, light weight, and high heat exchange efficiency, and is suitable for cooling a large-scale wind driven generator with strict requirements on volume and weight.
Description
Technical field
The present invention relates to a kind of generator cooler, is a kind of double-feedback aerogenerator air/water cooler specifically.
Background technology
Temperature rise is the important indicator that heat-producing devices such as motor, generator and transformer design and move, and indicates the degree of heat of heat-producing device, in order to prolong its useful life, must control its temperature rise, fully reduces temperature rise, must the outfit cooler of electric motor.Air/water cooler commonly used is vertical to be installed in the motor top cooling casing, electric drilling match height height, and overall volume is big, weight is big, and hot blast can't be rapidly and the cooler contact heat-exchanging by entering in the motor case in the cooling casing in the motor, and heat exchange efficiency is low, and is bad to the motor cooling effect.
Summary of the invention
For solve the prior art hollow water-cooled but device vertical be installed on the cooling casing in supporting height height, volume is big, weight is big, and heat exchange efficiency is low, the bad deficiency that waits of motor cooling effect, the invention provides a kind of simple in structure, volume is little, weight is little, the heat exchange efficiency height, the double-feedback aerogenerator air/water cooler of motor good cooling results.
The technical solution used in the present invention is: a kind of double-feedback aerogenerator air/water cooler, cooler bin is installed on motor case top, centre position, motor box top is provided with air outlet, the air outlet both sides of motor box top are provided with return air inlet, its technical characterstic is to be provided with the cooler of being made up of four side plates and Duo Gen cooling water pipe in the described cooler bin, four side plates through bolt in the motor box top, many cooling water pipes are positioned at the air outlet top and are communicated with the motor case through air outlet, air outlet is positioned at the below of many cooling water pipes between biside plate, and arbitrary side plate is provided with water inlet pipe and the outlet pipe that is communicated with cooling water pipe in the above-mentioned biside plate.
After adopting above technical scheme, the beneficial effect that the present invention reaches is: four side plates of this air/water cooler through bolt in the motor box top, the many horizontal cross-under of cooling water pipe are on corresponding biside plate, air outlet is positioned at the below of many cooling water pipes between biside plate, arbitrary side plate is provided with water inlet pipe and the outlet pipe that is communicated with cooling water pipe in the above-mentioned biside plate, the cooler whole height is low, volume is little, and the cooler of comparing the traditional vertical installation has alleviated overall weight; Hot blast in the motor case is entered in the cooler bin by the air port of setting out, in many horizontally disposed cooling water pipes water flowing directly and hot blast carry out heat exchange, hot blast enters residence time weak point in the cooling casing, the heat exchange efficiency height, hot blast is got back in the motor case body by the return air inlet of air outlet both sides after heat exchange, to the motor good cooling results, prolong motor useful life.
The present invention directly is communicated with motor case air outlet with horizontal being installed on of cooler in the cooler bin, shorten interior hot blast hot blast residence time in cooler bin of motor case and realize quick heat exchange cooling, it is simple in structure, compact, volume is little, in light weight, the heat exchange efficiency height is fit to volume, the strict large-scale wind generating motor cooling of weight are used.
