Description
Technical Field
The utility model relates to a fan, a high temperature resistant cooling blower for aerogenerator specifically says so.
Background
Generally, a cooling mode of a wind driven generator is a backpack type air-to-air cooling mode, and an external air-to-water cooling mode is used for ensuring the operation of the wind driven generator, and a primary cooling medium and a secondary cooling medium exchange heat through a cooling device and then cool the interior of the wind driven generator. However, the motor of the air-air intake fan for secondary cooling medium works for a long time, and the output shaft and the motor are both in high-temperature working conditions, so that the service life is influenced.
Disclosure of Invention
The utility model provides a simple structure can effectively cool off fan power input shaft and its driving motor's high temperature resistant cooling blower for aerogenerator.
The utility model adopts the technical proposal that: the utility model provides a high temperature resistant cooling blower for aerogenerator, includes fan spiral case, blade, motor, and the motor supports the connection outside the fan spiral case through the motor support, and the blade in the fan spiral case is inserted to motor play axle cross-under motor support, characterized by: the motor support is of an outer hollow structure, an outer wind wheel is connected to a motor output shaft in the motor support in a penetrating mode, the wind wheel comprises a radial wheel piece and an axial wheel piece, the radial wheel piece is close to the fan volute and faces the motor output shaft, and the axial wheel piece is close to the motor and faces the motor axially.
The blade is connected with a blade shaft in a penetrating way, and the blade shaft is connected with a motor output shaft in the motor support in an internal connection way.
The output shaft of the motor is connected with the blade shaft through a shaft coupling.
A motor base flange is arranged at the shaft outlet section of the shell of the motor and connected with a motor support.
The radial wheel sheet and the axial wheel sheet are connected to the two sides of the wind wheel seat through the wind wheel seat.
The utility model discloses a radial wheel piece cools off towards the motor play axle along with the motor goes out the rotatory air supply play axle of axle on the wind wheel, combines on the wind wheel axial wheel piece to cool off along with the motor goes out the rotatory air supply motor of axle towards the motor, and the wind wheel is installed in the motor support, and compact structure satisfies fan power input shaft and driving motor's cooling simultaneously, effectively extension equipment life.
