ABSTRACT:
A dimpled heat transfer surface for transferring heat energy from either a hot fluid or hot object to a cooler fluid, and method of making same. The heat transfer surface includes at least one plate for transferring heat energy from the hot fluid on one side of the plate to the cool fluid on the other side of the plate, and a plurality of intact spaced depression on one side of the plate thereby creating a plurality of intact projections on the other side of the plate. The depressions and projections are arranged to increase both the heat transfer film coefficient of the plate and the heat energy being transferred by the plate.
