Abstract
A heat exchanger tubing has one or more channels formed therein for fluid flow, with channel walls between the channels having openings extending between two opposing surfaces of the tubing. The channel walls are angled with respect to the opposing surfaces to increase the surface area of the openings. The tubing is tilted with respect to the headers in a heat exchanger assembly so that the openings in the tubing align with the direction of airflow passing over the heat exchanger. A heat exchanger assembly employing the tubing is effective without conventional fin stock, thus reducing the cost and manufacturing time when making the heat exchanger assemblies but without sacrificing heat exchange capability.
