Abstract: A heat sink comprising a base, fins attached to the base and a flow diverter in contact with the base or at least one of the fins. The flow diverter has a rectangular cross-sectional profile in a plane that is coplanar with and elevated above a plane of the base and spanning the entire separation distance, and, a segment of the flow diverter is angled towards the base to direct the fluid flow towards the base.

Abstract: A heat sink includes a base and a heat exchange element coupled to the base. The heat exchange element includes a foam structure that is coupled to the base.

Abstract: A heat sink includes a base and a heat exchange element monolithically connected to the base. The heat exchange element has a surface that at least partially bounds first and second paths through the heat exchange element. The surface forms an upper boundary of the first and second paths and includes an opening therethrough connecting the first and second paths.

Abstract: A heat sink includes a base and fins attached to the base. A flow diverter is in contact with the base or at least one of the fins and is configured to disturb a laminar flow region of a fluid flowing adjacent to at least one of the fins or the base.

Abstract: A heat sink includes a surface and a first active element connected to the surface. The first active element is configured to move from a first position relative to the surface to a second position relative to the surface. The movement alters the heat transfer characteristics of the heat sink.

Abstract: A fan includes a plurality of blades 9 carried by a hub housing 10 mounted on a rotatable motor shaft 6. The shaft 6 includes a heat pipe 11 to transfer heat from the motor bearings 7 and 8 to a heat dissipative plate 15. The fan is particularly useful for cooling electrical and electronic equipment housed within a cabinet, such as, for example, in a telecommunications arrangement.

Abstract: Apparatus including: a conduit body having a lining that bounds a channel having a longitudinal axis; the lining including a lining base; the lining including raised micro-scale features monolithic with the lining base. Apparatus including: a cavity body at least partially enclosing a cavity; the cavity having a lining that bounds a channel having a longitudinal axis; the lining including a lining base; the lining including raised micro-scale features monolithic with the lining base. Process including: providing a three-dimensional graphics design for a device having a superhydrophobic pattern of raised micro-scale features on a base, the base and the raised micro-scale features being monolithic; inputting the three-dimensional graphics design to a three-dimensional rapid prototype fabrication apparatus; and laying down build material and monolithically fabricating the base and the raised micro-scale features.

Abstract: A method for preemptively detecting fan failure is provided. The method may include measuring at least one parameter associated with the fan, such as sound, wobble, smoke, or the like, and predicting a time at which failure of the system is anticipated based on said measured parameter. Thereafter an indication of the predicted time at which failure of the system is anticipated is provided. Maintenance of the system to repair or replace the fans may then be scheduled as part of a regularly scheduled maintenance call, reducing the cost associated with the fan failure.

Abstract: A method is provided for cooling electrical equipment located in distinct regions in a cabinet. A first air flow is provided to a first region in the cabinet. A second air flow is provided to a second region in the cabinet. The temperature of the first and second air flows provided to the first and second regions is substantially equalized to provide similar cooling characteristics within the first and second regions. The equalization is accomplished via a heat exchanger arrangement that may be an active or passive system.
