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.

Abstract: A rack server has a base supporting a plurality of circuit elements, and a kinetic heat sink in direct contact with at least one first circuit element. The direct contact is configured to produce a heat-conduction relationship between the at least one first circuit element and the kinetic heat sink. The kinetic heat sink has a radial side spanning 360 degrees. The rack server also has a member for radially directing air from the kinetic heat sink. The member has an exhaust port spanning no more than about 180 degrees of the radial side, and the kinetic heat sink is configured to exhaust air from no more than about 180 degrees of the radial side. The exhaust port faces at least one second circuit element and is configured to direct air toward the at least one second circuit element.

Abstract: A centrifugal blower having at least one radial plane dividing its scroll into sub-sections which may vary as to cut-off points and axial and radial dimensions as well as axial displacement to meet requirements of individual application system flow paths.

Abstract: The disclosed system provides heat and/or moisture transfer between two counter-flowing air streams. The system comprises: a frame; a transfer wheel having a periphery spaced from the frame so as to form a gap therebetween, and including a transfer matrix mounted and rotationally secured relative to the frame so that the wheel can simultaneously rotate through the two separate, counter-flowing air streams; a sealing arrangement configured so as to seal the transfer wheel to the frame so that as the wheel rotates through the two separate counter-flowing air streams, the two air streams flow through the transfer matrix while remaining sealed from one another; and an electromagnetic actuator including rotational components secured relative to the wheel configured to generate flux across the gap and stationary components secured relative to the frame configured to impart a tractive force to the rotational components in response to polyphase power supplied to the stationary components.
