Abstract
A cooling fan comprising an outer housing. A motor support is fixed to the outer housing and a motor is mounted to the motor support. A hub is rotatably coupled to the motor and, with the motor support, forms a motor enclosure that substantially surrounds the motor. A plurality of blades extend radially from the hub and are arranged so as to generate a flow of air around the motor enclosure when the blades are rotated. The cooling fan also comprises a motor cooler comprising a flow path through the motor enclosure, wherein the flow path has a first opening and a second opening, wherein the second opening is disposed within an area of lowered downstream pressure so as to develop a differential pressure between the first and second openings and generate a flow of air through the motor enclosure as the motor operates.
