CN219220641U - Auxiliary radiator for cabin of wind turbine - Google Patents

Abstract

And the auxiliary heat dissipation device of the cabin of the wind turbine is transported. Because the temperature in the engine room is integrally higher due to long-time running of the unit, the effect of the cooling fan may be less ideal, the temperature of the oil temperature of the gear box and the temperature of the bearing of the generator are higher, load limiting or non-stop occurs, and electric quantity loss is caused. The composition of the utility model comprises: a louver frame (2) is fixed on the cabin cover plate opening (5) and positioned on the inner side of the cabin (4), and a cotton filter plate (1) is covered on the louver frame; the shutter frame comprises a square frame, and a plurality of louver blades (8) are connected in the frame through blade shafts (7). The utility model is used for assisting in heat dissipation of the cabin of the wind turbine.

Description

Detailed Description

Examples

An auxiliary heat dissipation device for a nacelle of a wind turbine, comprising: a cabin cover plate opening 5, wherein a shutter frame 2 is fixed on the cabin cover plate opening and positioned on the inner side of the cabin 4, and the shutter frame is covered with a cotton filter plate 1;

the shutter frame comprises a square frame, and a plurality of louver plates 8 are connected in the frame through a louver shaft 7.

The auxiliary radiator of the cabin of the wind turbine is characterized in that a rubber sealing ring 3 is arranged between the shutter frame and the cabin cover plate opening.

Firstly, the shutter frame is mounted on a cover plate opening reserved in an original cabin below a generator and a coupling, two sides of the shutter frame are respectively attached to a cabin wall by a plurality of welding studs, a plurality of studs on one side of the shutter frame penetrate through the cabin wall, and the outer side of the cabin wall is fastened by a self-locking nut. A rubber sealing ring is arranged between the cabin wall and the shutter frame and is sleeved on a screw rod of the shutter frame for fixation. The M8 spring flat pad and the nut are used for fastening the shutter, the filter cotton mounting plate and the shutter frame together.

The filter cotton is used for effectively filtering catkin, cotton wool and larger particle impurities, so that the heat exchange effect with outside air is guaranteed, and the availability of the wind turbine generator is improved in the aspects of reliable operation of the fan, reduction of high-temperature failure rate.

High-temperature air of the engine room is subjected to heat exchange with external air through the auxiliary heat dissipation opening, cold air outside the engine room enters the engine room, the temperature of the engine room is reduced integrally, the integral temperature of the engine room is improved effectively, the heat dissipation effect of the gearbox and the generator is ensured, and therefore the running stability of the unit is improved, and fan faults and production cost are reduced indirectly.

The louver blades of the louver are adjusted in angle, so that the louver can be adjusted to be maximum in summer, the cabin radiating effect is guaranteed, the overall temperature in winter is low, and the angle of the louver blades is adjusted to be small, so that the temperature in the cabin can be guaranteed.
