Abstract
A technique for enhancing heat transfer ventilation grooves is provided which allows the cooling groove dimensions to be minimizes while satisfying endwinding cooling requirements. Groove dimension may be minimized by including surface manifestations and/or selecting a non-linear groove configuration or shape to enhance heat transfer.
