Benefits of technology
[0008]By means of the present invention, electronics applications with high-density component populations may be efficiently and effectively cooled with a low-volume cooling module. The specific arrangement of forward-curved centrifugal blowers of the present invention facilitates the creation of a cooling module of low physical volume that nevertheless generates desired levels of air movement power at substantially reduced noise. Electronics chassis manufacturers, therefore, are able to achieve high performance within small-volume packages.
Problems solved by technology
Designers of electronic equipment have become increasingly challenged to provide high-power devices in relatively small packages.
Conventional system designs often employ fans that are not well matched to the system pressures, or do not move air efficiently within the space constraints, and result in unacceptable noise, and relatively large power consumption.
Relatively high aerodynamic efficiencies can be achieved with this type of air mover, but unfortunately they require high rotational speeds that typically result in unacceptable acoustic signatures.

A cooling fan module for motivating air flow through an electronics chassis includes an enclosure having an air inlet through which cooling air flow is motivated by at least two centrifugal blowers disposed within the enclosure. The centrifugal blowers operate in parallel to motivate the cooling air flow along a first direction vector, while the respective axes of rotation of the centrifugal blower impellers are in substantial axial alignment with one another, and parallel to the first direction vector.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. provisional Patent Application Ser. No. 61 / 356,374, filed on Jun. 18, 2010 and entitled “Cooling Module with Multiple Parallel Blowers”, the content of which being incorporated herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to cooling systems generally, and more particularly to a cooling fan module for motivating cooling air flow through an electronics chassis, wherein the cooling fan module is substantially more efficient and produces substantially less noise than conventional cooling fan arrangements, without requiring increased volume.BACKGROUND OF THE INVENTION[0003]This invention relates to a module, commonly referred to as a fan tray, designed to provide cooling flow to an electronics apparatus. Specifically, the module contains a parallel flow arrangement of centrifugal blowers. The present arrangement optimizes performance of the module by employing high ef...
