摘要： An air mover, such as a cooling fan, comprises a motor and an impeller which is driven by the motor to generate a flow of air through a flowpath. The motor comprises at least one inlet opening and at least one outlet opening, each of which is in fluid communication with the flowpath. In operation of the air mover, a pressure difference between the inlet and outlet openings causes a portion of the flow of air to flow into the inlet opening, through the motor and out the outlet opening to thereby cool the motor.

摘要： A method for designing a fan having a motor which drives an impeller comprises providing an outlet guide vane assembly which includes a hub and a plurality of guide vanes that extend radially outwardly from the hub, attaching the hub to the motor, determining an approximate amount of heat which is generated by the motor during operation of the fan, determining an approximate surface area which is required to dissipate the heat into a surrounding air stream, and configuring the guide vanes to comprise a total surface area which is approximately equal to the required surface area. In this manner, the heat generated by the motor during operation of the fan can be dissipated by the guide vanes.
