ABSTRACT:
An evaporator for an automotive air conditioner having a plurality of tubes therein arranged side by side so that spaces are provided for air centers mounted between the sidewalls of the tubes. Each tube is formed from a pair of interfacing plates having ribs indented in a predetermined pattern therein to form discrete fluid flow sections within each tube. The ribs are interconnected in such a manner that the sections effectively vary and tailor the flow of the heat exchanger fluid to reduce or substantially eliminate dry out areas in each tube thereby increasing heat exchanger tube and evaporator efficiency.
