Abstract
A manifold structure is defined by a pair of stacked plates which define a void: one of these plates has three or more aperture-surrounding bosses which project into the void; the other of these plates has a plurality of protuberances. Each of the protuberances engages between a respective pair of the bosses. A heat exchange element is formed of a plurality of stacked plates, these plates defining a stack of tubes. The tube stack interiorly defines a plurality of U-shaped passages, these passages being distinct from one another. Each tube defines a respective one of the U-shaped passages and is received in plug-fit relation by a respective one of the bosses. The tubes, bosses and protuberances separate the void into a pair of manifolds. Each of the U-shaped passages leads from one of the manifolds to the other of the manifolds.
