Abstract
A multi-pass heat exchanger is provided wherein the heat exchanger is comprised of a plurality of stacked heat exchange plates defining a plurality of alternating first and second fluid channels interconnecting respective pairs of manifolds. At least one of the manifolds in the pairs of manifolds is in the form of an annular manifold structure which divides the heat exchanger into at least a first part and a second part thereby forming at least a two-pass flow path. The annular manifold structure is provided by a generally tubular manifold insert having one end embedded within the manifold. A first annular manifold flow passage communicates with one of the sets of fluid channels in the first part of the heat exchanger and a second, central manifold flow passage communicates with the corresponding set of fluid channels in the second part of the heat exchanger.
