Claim:
1. A cooling assembly, comprising: a receiving area on a first surface of a first plate that receives at least one heat generating element; a heat spreader including an inner surface and at least one outer surface; said inner surface affixed to a second surface of said first plate adjacently opposite to said receiving area to conductively dissipate heat generated from said at least one heat generating element; a plurality of heat dissipating fins spaced apart from each other; each said heat dissipating fin coupled to a second plate and extending transversely therefrom to couple to said heat spreader, wherein said second plate is positioned opposite to said first plate with a space created therebetween to form a channel for a fluid to flow through; and a plurality of micropillars disposed on a bottom surface of said heat spreader, wherein an end of the heat dissipating fins contacts the bottom surface of the heat spreader, wherein said micropillars are disposed in pairs around the end of the heat dissipating fins at an angle within a range of 70-90 degrees between a reference line and a central line of said pair, said reference line being in parallel with an initial flow direction of said fluid and crossing a center of the end of the heat dissipating fin, said central line crossing the center of the end of the heat dissipating fins and a location in a middle of paired micropillars, wherein when said fluid flows through said channel between said first plate and said second plate, said plurality of heat dissipating fins, said heat spreader and said plurality of micropillars in combination create an enhanced turbulent flow upon said fluid so as to effectively dissipate heat from said heat spreader through said fluid.
