Abstract
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.
Claims12
A cooling fan module for motivating air flow through an electronics chassis, said module comprising:
- an enclosure having an air inlet through which the air flow is drawn from said electronics chassis;
- at least two centrifugal blowers disposed within said enclosure and in parallel motivating the air flow along a first direction vector through said air inlet, each of said centrifugal blowers comprising:
- (i) a scroll housing defining an air inlet and an air discharge;
- (ii) a forward-curved impeller having a diameter dimension, and defining an axis of rotation, said axis extending through said housing air inlet and substantially parallel to said first direction vector;
- and
- (iii) a motor for rotation of said impeller about said axis,
- wherein said respective axes of rotation of said centrifugal blower impellers are in substantial axial alignment with one another.
A cooling fan module for pulling air flow through an electronics chassis, said module comprising:
- an enclosure having an air inlet through which the air flow is drawn from said electronics chassis;
- a first set of a plurality of centrifugal blowers disposed within said enclosure and in parallel motivating the air flow along a first direction vector into said enclosure, each of said centrifugal blowers of said first set comprising;
- (i) a scroll housing defining an air inlet and an air discharge;
- (ii) a forward-curved impeller having a diameter dimension, and defining an axis of rotation, said axis extending through said housing air inlet and substantially parallel to said first direction vector;
- and
- (iii) a motor for rotation of said impeller about said axis,
- wherein said respective axes of rotation of said centrifugal blower impellers are in substantial axial alignment with one another;
- a second set of one or more blowers disposed within said enclosure and motivating the air flow along a second direction vector into said enclosure, said second direction vector being substantially perpendicular to said first direction vector.
