摘要： A system for cooling an electronics enclosure comprises a plurality of fan modules. Each fan module comprises, a motor for driving a fan at a variable rotational speed, a microcontroller for controlling the rotational speed of the motor, an interface for electronically communicating between the microcontroller and an infrastructure controller external to the fan module, the infrastructure controller providing a target speed to the microcontroller, a memory for storing data including speed avoidance zones, wherein when the target speed falls within one of the speed avoidance zones, the microcontroller controls the motor speed to be slightly outside the speed avoidance zone.

摘要： A cooling fan includes an outer housing. A motor support is fixed to the outer housing and a motor is mounted to the motor support. A hub is coupled to the motor and, with the motor support, forms a motor enclosure that substantially surrounds the motor. Multiple 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 includes a motor cooler including 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.

摘要： The present invention provides a ventilated casing for an electronic device. The ventilated casing includes a housing which has a ventilation inlet and a ventilation outlet. The ventilated casing also includes a high speed fan for moving air from the ventilation inlet to the ventilation outlet to dissipate heat that in use is generated by electronic components positioned in the housing. The fan has a blade, a motor and an air guiding portion positioned near the blade. The air guiding portion has a first mode resonance frequency that is greater than the rotational frequency of the fan.
