A cooling system for a turbine blade outer air seal that is positioned in close proximity to a tip of a rotatable turbine airfoil to seal the gap between the tip of the turbine blade and the blade ring carrier. The turbine blade outer air seal may be formed from a housing including a cooling fluid collection chamber and one or more vortex cooling channels in fluid communication with the cooling fluid collection chamber via one or more vortex channel feed holes. In one embodiment, a plurality of vortex cooling channels may extend from proximate to an upstream edge of an outer sealing plate of the outer air seal to a downstream edge of the outer sealing plate. During use, cooling fluids pass through the vortex channel feed holes and into the vortex cooling channels, in which vortices may be created.
