Abstract
A transmission oil cooler has spaced elongated plates secured at the margins and ports at either end to define an oil flow channel. A center disposed between the plates for creating turbulence in the oil and enhancing heat transfer comprises a metal sheet folded to form generally planar fins in side-by-side relationship and the fins having louvers extending over most of their area. The center is disposed in the flow channel with the planes of the fins transverse to the oil flow or alternatively with the planes of the fins parallel to the oil flow.
