Abstract:
1. A thermal distribution assembly comprising a plate having surface features residing on a surface thereof, said surface features comprising a plurality of circular cavities having inwardly projecting fins; an exposed surface area of said plate and said surface features; a manifold attached to said plate, said manifold having at least one microjet array and at least one distributed drain array; a plurality of cooling cells within said manifold, each having a microjet substantially at a center thereof, whereby each of said circular cavities is aligned with a single cooling cell and said microjet residing substantially at a center of each said circular cavity; and a cavity residing between said manifold and said exposed surface area, said surface features having a height ranging from about 30% to about 80% of a height of said cavity if 100% height is not feasible according to a prescribed pressure drop budget; whereby said microjet array emits said fluid and said surface features of said plate delay a velocity decay of said fluid within a wall jet region of said cavity for enhancing thermal control of said assembly, thereby preserving fluid vortexes created by said microjets within said cavity.
