ABSTRACT:
A heat exchanger surface for a refrigeration system comprising a wavy heat exchange surface formed with a series of peaks and troughs extending over the wavy surface in a direction substantially perpendicular to the direction of airflow. The wavy surface includes a plurality of holes aligned in first and second rows parallel to the peaks and troughs, where the aligned holes within each row are separated by a smooth area. The wavy surface includes louvers for enhancing heat transfer. The louvers are located between the peaks and troughs on the wavy surface, but are not located in the smooth areas between the aligned holes of the first and second holes.
