Abstract:

Cavity plate and jet nozzle assemblies are presented for use in cooling an electronic module. The assemblies include a cavity plate having one or more blind holes formed therein and one or more jet nozzles each configured to reside within a respective blind hole of the cavity plate. A lower surface of the blind hole and/or jet nozzle is curved to facilitate the flow of fluid from the blind hole after impinging upon the lower surface of the blind hole. Various jet nozzle configurations are also provided which employ pedestals or radially extending fins. Further, the radially extending fins may interdigitate with inwardly extending fins on the inner sidewall of a respective blind hole in the cavity plate. Methods of fabricating the cavity plate and jet nozzle assemblies are also presented.
