The invention discloses a cooling air flow guide distribution device. The cooling air flow guide distribution device comprises a flow guide box arranged on the outer side face of a box type wind driven generator; the interior of the flow guide box is divided into an air inlet distribution cavity and an air exhaust collection cavity; an air supply pipeline is connected to an air supply port of theair inlet distribution cavity; an air distribution port communicates with the end part of the box type wind driven generator; an exhaust pipeline is connected to an exhaust outlet of the collecting cavity; and the air collection port communicates with the side surface of the box type wind driven generator. The invention further discloses the box type wind driven generator. The box type wind drivengenerator comprises a box body and the cooling air flow guide distribution device arranged on the upper side surface of the box body; an axial air blowing cavity is formed in the end part of the boxbody and communicates with the air inlet distribution cavity of the cooling air flow guide distribution device; and a radial air exhaust cavity in the inner periphery of the box body communicates withthe air exhaust collection cavity of the cooling air guide flow distribution device. The cooling air flow guide distribution device is used for distributing cooling air to the interior of the generator, enabling the cooling air to directly mix with hot air in the wind driven generator and discharging the mixed cooling air and hot air in the radial direction, and therefore the cooling efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of wind power, in particular to a cooling wind diversion distribution device and a box-type wind power generator. Background technique [0002] The cooling methods of the existing box-type wind turbines are mostly overhead air-to-air coolers or air-to-water coolers. However, these two coolers have complex structures, many failure points, expensive manufacturing costs, and the heat exchange between the hot air inside the generator and the cooling medium in the cooler does not occur in contact, and the heat exchange efficiency is low, which limits the power of the generator density. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a cooling air diversion distribution device for distributing cooling air to the wind power generator, reducing the temperature inside the wind power generator, and simplifying the cooling system ...
