Problems solved by technology

Since the inner air path of the cooler itself does not have a fan, the circulating air is realized by the impellers at both ends of the rotor. When designing the generator, the length of the rotor must be considered to be able to install the impeller, so that the overall length and size of the generator are increased and the volume is increased.
In addition, the pipes arranged in a rectangular shape have great resistance to the wind, and the phenomenon of low wind speed is easy to occur in some places, forming dead angles and affecting the effect of heat exchange.
The external air path adopts a single fan, and the pressure on the surface of the tube sheet is unequal. The pressure in the middle is high, and the pressure in the surrounding area is small. Difference

Embodiment Construction

[0011] The cooler and the wind generator are installed in a knapsack style, the entire cooler is buckled above the wind generator, and the cooler and the motor are tightly connected with gaskets. Such as figure 1 , 2 As shown, the cooler includes an external air path fan 1, a fume hood 3, a cover plate 5 with a molded disc-shaped motor mounting seat, a tube plate 10, an M-shaped arrangement of heat exchange tubes 9, air inlets and outlets 11, 2 and a The centrifugal fan and the motor form the inner air path fan. The heat exchange tube 9, the tube plate 10 and the separator 4 form the core body of the cooler. The heat exchange tube 9 passes through the tube plate 10 and the separator 4. The gap between the plates 4 is small to ensure that the leakage on both sides of the partition is small, such as image 3 As shown, the two ends of the heat exchange tube 9 and the tube sheet 10 are connected by expansion joints; the core of the cooler is divided into three parts by two parti...

Abstract

The invention relates to an air-air cooler used for a wind power generator, in particular to a cooler of a wind power generator with large power. A backpack type installation way is adopted between the cooler and the wind power generator; the whole cooler is buckled on the wind power generator and comprises an outer wind path fan, a ventilating cabinet, a pipe plate, heat exchange pipes, a wind collector, a wind inlet and a wind outlet, wherein a cover plate with a moulding disk-type motor installation seat is arranged on the ventilating cabinet; an inner wind path fan comprising a centrifugal fan and a motor is installed on the cover plate; a push insertion fastening installation way is adopted between the cover plate and the ventilating cabinet; a cove disc-type machine soleplate can reduce the overall height of the wind power generator after the machine is equipped and is easy to let the cooler move and be operated in the machinery room.

Description

technical field [0001] The invention relates to an air-to-air cooler for a wind power generator, in particular to a high-power wind power generator cooler. Background technique [0002] The cooler of the generator on the existing 1.5MW wind power equipment is composed of a single external air path fan, a fume hood, a tube plate, heat exchange tubes arranged in a rectangular shape, and an external air path with squares and circles. The cooler is installed on the generator, and the internal air path of the cooler is connected with the inner cavity of the generator. The rotation of the rotor of the generator drives the impellers at both ends of the rotor to rotate to generate wind bundles. The wind bundle takes away the heat generated by the loss of the motor, enters from the middle of the cooler, passes through the outer surface of the cooler tube, and returns to the inner cavity of the motor from both ends of the cooler to form a circulating air. The wind generated by the f...
