Abstract

A radiator section of a radiator is provided that has a plate that defines a plurality of ducts for the flow of a fluid there through. A first one of the ducts has only four convex ridges and only two concave furrows. Also, a second one of the ducts located closer to a longitudinal centerline of the plate than the first duct has only eight convex ridges and only six concave furrows.
