Abstract
In accordance with certain embodiments, a cooler for multiple tube banks features a series of parallel and planar fins that have upstream louvers to direct incoming air through a fin near a first row of tubes and a downstream set of louvers near an adjacent tube row to direct air back through the same fin before the air exits. By way of example, the upstream louvers have the negative slope of the downstream louvers and a constant angle from louver to louver within a bank. A constant length in a section view may be provided.
