Abstract (en)

A heat exchanger for transferring heat from a body through heat transfer elements to streamlines of a laminar flowing coolant fluid has fin elements arranged in a row and column pattern, with elements staggered transversely to the flow so that no fin is aligned with its nearest or next nearest neighbours in either the row or column direction. During fluid flow across the heat exchanger, each streamline contacts one heat transfer element and is directly heated exactly once before any streamline contacts more than one element and is directly heated twice. Thus, every streamline of the fluid is used for heat transfer. After an upstream heat transfer element heats its wake-core, enough time elapses before these streamlines flow close to a downstream element to allow heat to diffuse sideways. Thus, no downstream heat transfer element is in the immediate thermal wake-core of any upstream heat transfer element.
