Abstract
A micro-circuit cooling module for providing endwall cooling for a vane assembly in a gas turbine engine. The micro-circuit cooling module includes an outer perimeter rail, an upper plate and a lower plate defining a mixing chamber therein. A first plurality of spaced apart strip elements extend along a first direction in an upper channel of the mixing chamber, and a second plurality of strip elements extend along a second direction opposite to the first direction in a lower channel of the mixing chamber so that the first plurality of strip elements and the second plurality of strip elements form a criss-cross configuration. Air enters the module through metering holes in the lower plate and flows through the mixing chamber across the criss-cross elements in a turbulent manner and exits the module through slots in the upper plate.
