A containment (5) for a heat producing device has cooling fins (15) to dissipate the produced heat. In this type of cooling fin arrangement the cooling fins comprise, traditionally, smooth outer surfaces (17) so that in a boundary layer (18) the flow pattern of the cooling fluid along the cooling fins is laminar. The present invention provides means (20) to break this laminar flow pattern in the boundary layer and herewith improves the heat transfer from the cooling fins to the cooling liquid. This invention can advantageously be applied to viscous fan clutch covers.
