US 2003/0213441 A1 · Engine cooling system and method for making same

Abstract

Engine cooling system and method for making same wherein an engine, engine casing, or component thereof or a component related thereto has at least one cooling fin (18) having at least a portion of an edge surface (32) including an engraved, or intagliated portion (40). Preferably the surface edge includes a plurality of itagliated portions (40) with each portion including at least two elongated concavities being in preselected orientation and relationship to each other to improve the cooling efficiency of the fin and thus allow the engine to operate in wider, more extreme range of temperatures and environments. The present invention is particularly well suited, but not limited to air-cooled engines and related components such as component covers, inspection/access covers, and oil coolers and is therefore readily adaptable to engines used to propel motor vehicles such as, but not limited to, motorcycles.
