Patent number: 6538885Abstract: One or more impingement plates, each of which includes one or more apertures, is located within an card cage running from top to bottom and from back to front of the card cage. Each impingement plate is located adjacent to one or more electronic components to be cooled. Channels formed on either side of the impingement plate allow for the ingress of a cooling fluid, the forcing of the cooling fluid through the one or more apertures within the impingement plate toward the electronics to be cooled, and the egress of the cooling fluid after it's contact with the electronics.Type: GrantFiled: September 15, 2000Date of Patent: March 25, 2003Assignee: Lucent Technologies Inc.Inventor: Kaveh Azar

Publication number: 20020056544Abstract: A heat exchanger with a radial fin field. The fin field comprises a central region extending between the inlet and outlet regions. Along both sides of the central region are a plurality of fins extending from the inlet region to the outlet region at an angle to the central region, wherein the angular mounting increases progressively towards the respective sides of the heat exchanger. As such, the lengths of the fins in the fin field are not uniform. The layout of the fins in the fin field provide for a portion of the fluid passing through the fin field to be drawn out along the sides of the fin field via the shorter length fins and by low pressure formed along the sides from fluid flow by-pass. Accordingly, the fin field utilizes the low pressure created by flow bypass to vent relatively high pressure fluid within the fin field.Type: ApplicationFiled: January 7, 2002Publication date: May 16, 2002Inventor: Kaveh Azar

Patent number: 6301779Abstract: A plurality of substantially similar fins is produced from the thermally conductive and formable sheet stock, for example aluminum or copper, preferably using a set of matched forming dies. Each die in the set produces a fin that is cupped in side elevation. Each fin has two flanges (in the preferred embodiment) extending from the base portion of the cup, and the fin is preferably rectangular in plan. The die cavities are substantially identical in geometry, but differ slightly in dimension so that the base portion of the cup-shaped fin-pair produced by each die in a set varies in width. Each die in the set includes a feature for producing a locating lug or dimple, or alternatively a hole, in each fin produced. The plurality of substantially geometrically identical, but dimensionally differing fin-pairs are then assembled in a nested stack in accordance with the invention.Type: GrantFiled: October 29, 1998Date of Patent: October 16, 2001Assignee: Advanced Thermal Solutions, Inc.Inventor: Kaveh Azar

Patent number: 6263955Abstract: A heat exchanger is disclosed for dissipating heat from a heat generating component. The heat exchanger comprises a thermally conductive base in thermal communication with the component, a plurality of thermally conductive plate fins affixed to the base wherein the plate fins define a fin field and channels, and fluid control for controlling the fluid flow within the fin field. Fluid flow enters the fin field at an inlet region and flows through the channels to an outlet region, i.e. from left to right across the figures illustrated.

Patent number: 5304846Abstract: Dissipation of the heat produced by the operation of electronic circuitry may be improved by a heat sink which comprises a flat base from which a number of vertical fins extend. The fins are parallel to one another and define a number of parallel channels into which coolant flow is directed. The thermal resistance of the heat sink is optimized by setting fin thickness and channel width parameters to appropriate values. The heat sink may be attached in a heat conductive manner to a heat producing electronic component. One or more of these heat sinked components may be laid out in an in-line or staggered arrangement on a support in the form of a circuit pack. Cooling fluid is delivered to the circuit pack in a variety of ways to cool the heat sinked components. A method of determining the optimum fin thickness and channel width parameters involves determining a relationship between total thermal resistance of the heat sink and combinations of fin thickness and channel width parameters.Type: GrantFiled: June 1, 1993Date of Patent: April 19, 1994Assignee: AT&T Bell LaboratoriesInventors: Kaveh Azar, Richard E.
