Cooler

Abstract

A cooler, having individual cooling elements (1) of stacked construction having ducts (25) extending in parallel to one another, each of which delimits a flow chamber (29) for the throughflow of a liquid medium to be cooled, between which at least two layers (3, 5) of individual rows of meandering fins (34) extend, which for the throughflow of air jointly delimit a further flow chamber (26, 28) each, is characterized in that the respective one flow chamber (29), free of obstacles, permits a laminar flow of the liquid medium through the assignable duct (25) in one throughflow direction, in that the height (H1) of each fin (34), viewed transversely to the direction of throughflow of the liquid medium, has at least the same height as the free throughflow cross section of the flow chamber (29) of the adjacently arranged duct (25), viewed in parallel to the extension of the respective fin (34), and in that in every layer (3, 5), a plurality of rows (36) of several fins (34) are arranged in succession, which each viewed in the direction of throughflow of the duct (25) are offset from each other.
