Abstract

The utility model relates to an air-water cooler used for 1.5-2.0 MW direct drive wind turbine generators, which comprises a cooler core, an air feeding tube, a centrifugal fan and an air discharging tube. The center of the air feeding tube is designed into a center deviated from the cooler core and an air inlet of the cooler core and an air outlet of the air discharging tube are in the same plane. The air-water cooler has a structure covering a small space, so that a plurality of the air-water coolers can be assembled on the end face of the generator. Wind can evenly spread into a motor and pass through all stator coils of the motor, thereby avoiding dead angles and local overheating, and having good effects in heat transferring. The air-water cooler can be installed vertically on the end face of the generator because the generator has a horizontal structure, and even if the cooler leaks, water can not enter the inside of the generator. The air-water cooler has the advantages of small volume, compact structure, good effects in heating transferring and high reliability, and the like.

Description

A kind of wind power generator air/water cooler
Technical field
The utility model relates to a kind of 1.5-2.0MW of being used for level direct drive type wind power generator air/water cooler.
Background technology
The above wind power generator air/water cooler of existing 1.5MW adopts the Backpack type structure to be installed in the top of motor, its shell is a rectangular box that is welded by steel plate, the cooler air inlet that is connected with the motor air outlet is arranged at the bottom, top is air outlet, and cooler inside is provided with parts such as ventilation blower, cooling core body and filter.Ventilation blower makes heat that motor produces enter the air inlet of cooler by circulated air from the motor air outlet, and through cooling core body, the cooling core body internal arrangement has the fin cooling water pipe, is connected with recirculated cooling water in the pipe.Hot blast becomes Cryogenic air through behind the cooling core body, and Cryogenic air is come out by the air outlet of blower fan from cooler, enters motor internal from the motor air intake vent again, makes cold and hot air seal circulation exchange, and motor obtains cooling.This kind cooler of electric motor dock assembling into and out of the going out of air port and motor, air intake vent, the bottom surface is the same big with the top-surface area of motor, and higher for the core body aspect ratio that satisfies the heat exchange property cooler, the volume of cooler integral body is big.Because cooler is assemblied in the top,, will jeopardize the motor safety running in addition as cooling core body generation percolating water.
The utility model content
Air/water cooler on the directly driven wind-powered generating set of MW level that the purpose of this utility model provides that volume is little, compact conformation, good effect of heat exchange, reliability are high.
The utility model comprises cooling core body, air intake tube, centrifugal blower, chimney fan, this cooling core body is made up of last collecting main, cooling water pipe, whole aluminium fin, lower header, casing, casing is provided with inlet flange frame and outlet(discharge) flange frame, the inlet flange frame is installed on the air outlet of generator end face, and the suction flange of outlet(discharge) flange frame and air intake tube is fastened and connected; Parallelogram is made in the two sides of air intake tube, makes the center of air intake tube misalignment cooling core body, and the bottom of air intake tube is provided with suction flange, and the upper surface of air intake tube is provided with outlet(discharge) flange; Centrifugal blower is installed on the outlet(discharge) flange of air intake tube, and the chimney fan that the import and export two ends are shaped on flange is connected with the air outlet of centrifugal blower, and chimney fan is made elbow side's horn structure, the import that makes chimney fan with export into an angle of 90 degrees.
Because parallelogram is made in the two sides of air intake tube, can be so that the center of the misalignment cooling core body of centrifugal blower, the air intake vent of whole assembling back cooling core body becomes same plane with the air outlet of chimney fan, wind direction 180 degree that just taking a turn for the better, and the air outlet of the air intake vent of cooling core body and chimney fan is fully approaching.This kind air/water cooler structure occupation space position is little, make a plurality of air/water coolers can be assembled to the end face of generator, realized that hot blast alternately comes out to enter cooling core body from a zone of stator winding, cooled cool breeze enters stator winding through chimney fan another zone from the side.And the wind bundle evenly diffuses into motor through behind the tubaeform chimney fan, makes motor stator winding that distinguished and admirable mistake all be arranged, and does not produce the dead angle, the local overheating phenomenon can not occur, and the heat exchange effect is very good.Because generator is a horizontal type structure, air/water cooler is vertically mounted on the end face of generator, even the seepage incident appears in cooler, moisture can not enter generator inside yet, and not entail dangers to generator, so reliability is very high.
