Abstract: 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.

Abstract: 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. Each fin-pair in the stack is substantially identical in geometry but the base portion of each fin is successively smaller in dimension, moving axially from top to bottom of the fin stack, to allow for the nesting and so that edges of successive fins define gaps of predetermined dimension. The dimple allows for registration and fine alignment and as the nested dimple substantially align themselves as each fin is assembled in the stack. An interference fit between the dimples may be used to secure the assembled stack. Conventional fabrication techniques are optionally used, including bonding, welding, and brazing, to secure the nested fins to each other. Alternatively, a through hole may be used to effectuate both location of the nested fins and provide for mechanical fastening.

Abstract: 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. In a first embodiment of the invention, the heat exchanger comprises a flow guide extending over a top region of the fin field. The flow guide comprises a front portion adjacent to the inlet region of the fin field extending a predetermined distance in front of the fin field, and extending at an angle relative to the front plane of the fin field. The mounting of the flow guides across the top of the fin field and forward of the inlet region enhances acceleration of fluid flow at both the inlet and exhaust regions. In a second embodiment of the invention, the flow guide extends from an area forward of the inlet region to an area rearward of the exhaust region. The portion of the flow guide adjacent to the inlet region is similar to that of the first embodiment of the invention, and the portion of the flow guide adjacent to the exhaust region extends at an obtuse angle relative to the exhaust region. The mounting of the flow guide in the second embodiment of the invention both accelerates fluid flow adjacent to the inlet region and decreases pressure at the exhaust region. Accordingly, mounting of the flow guide across the top of the fin field and across the inlet and outlet regions as disclosed provides enhanced fluid flow through the heat exchanger.

Abstract: 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 means for controlling the fluid flow within the fin field. In one embodiment, the fluid control means utilizes the low pressure created by flow bypass to vent relatively high pressure fluid within the fin field. Alternatively or in conjunction, the fluid control means substantially prevents premature egress of fluid from the top of the fin field caused by the high pressure region within the fin field.

Abstract: 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. A contour plot is produced in accordance with the relationship referred to above. The contour plot shows regions of optimum heat dissipation for heat sinks in accordance with the geometry identified here.
