IMPINGEMENT-CONVECTIVE COOLING SYSTEM

A heated plate is cooled by cooling fluid impinging thereon from a plenum partially defined by a second plate spaced therefrom. Apertures in the latter plate provide communication between the plenum and the cooled plates. For the purpose of increasing cool fluid heat transfer of the impinging jets,...

Beschreibung
Zusammenfassung:	A heated plate is cooled by cooling fluid impinging thereon from a plenum partially defined by a second plate spaced therefrom. Apertures in the latter plate provide communication between the plenum and the cooled plates. For the purpose of increasing cool fluid heat transfer of the impinging jets, each of the apertures is provided with a varied diameter along its length, the smallest diameter extending over a given portion of the aperture length to form a throat. The ratio of throat length over throat diameter is less than 0.35. The aperture cross section between the throat and maximum diameter may be of any convenient configuration, for example conical or counterbored.
