Air blower for cooling motor vehicle engines has additional air outlet for cooling electronic controller so even if fan fails electronic controller is cooled by air flow produced by other fan

摘要

The device has two mutually independent adjacent fans (3,7), each with a fan wheel (5,9) with an outer ring (6,10) driven by a motor (4,8), whereby the fans are controlled by a common electronic controller (2). An additional air outlet for cooling the electronic controller is attached so that even in the event of a fan failure the electronic controller is cooled by an air flow produced by the other fan.
