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. 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. The heat exchanger of the present invention comprises a fin field having an open region formed by the novel configuration and layout of the individual fins forming the fin field. The open region may be formed in various sections of the heat exchanger for achieving the desired results. The open region reduces friction on fluid passing through the channels of the fin field. In an alternative embodiment, the heat exchanger may comprise a flow guide extending across a top portion of the heat exchanger, wherein the flow guide has a plurality of turbulators for disturbing the fluid flow above the fin field and removing stagnation of fluid from the top region of 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.

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.
