Abstract

A method of forming a cooling structure for a heat-dissipating surface includes arranging a heat spreader layer adjacent the heat-dissipating surface, bonding a coldplate directly to the heat spreader layer opposite the heat-dissipating surface, and forming an intermetallic bond between the heat spreader layer and the coldplate. The coldplate is bonded to the heat spreader layer using ultrasonic additive manufacturing.
