CONIC-SECTIONED PLATE AND JET NOZZLE ASSEMBLY FOR USE IN COOLING AN ELECTRONIC MODULE, AND METHODS OF FABRICATION THEREOF

摘要

Impingement plate and jet nozzle assemblies are presented for use in cooling an electronic module. The assemblies include a thermally conductive plate having a first main surface and a second main surface with a plurality of concave surface portions formed in the second main surface extending towards the first main surface. Each concave surface portion has a conic section profile. A plurality of jet nozzles are disposed above the thermally conductive plate with each jet nozzle being aligned over a respective concave surface portion, wherein fluid introduced into a concave surface portion through the respective jet nozzle impinges upon a lower portion thereof and flows outward along the concave surface portion. Each conic section profile is one of an elliptical section, a circular section, or a parabolic section.
