Abstract

A heat exchanger including flat tubes having cooling passages for a gas and a bypass for the gas separate from the cooling passages, and coolant channels defined between every two flat tubes adjacent the tube passages and spaced from the bypass of the tubes. The tubes define a cooled area adjacent the passages and an uncooled area adjacent the bypass substantially spaced from the channels.
