Abstract
An improved heat sink apparatus that utilizes either natural or forced convection to transfer heat generated by a high temperature medium to a lower temperature medium or converts cold energy from a low temperature fluid or solid medium to a different or higher temperature stage or condition of energy. The apparatus includes a thermally conductive base plate, a plurality of thick corrugated finned assembly components constructed and arranged in abutting relationship and offset from each other so as to cause a circuitous path of fluid flow therethrough. The apparatus also may include the base plate and a plurality of thick, sawtooth shaped, or segmented fins mounted thereon. The length of fluid travel from one finned component to an abutting finned component along the heat transfer surface is controlled in order to prevent development of thermal boundary layer on the inner surface of the finned assembly components.
