Abstract

See full text

Self-enclosing heat exchangers are made from stacked plates having raised peripheral flanges on one side of the plates and continuous peripheral ridges on the other side of the plates, so that when the plates are put together, fully enclosed alternating flow channels are provided between the plates. The plates have raised bosses defining fluid ports that line-up in the stacked plates to form manifolds for the flow of heat exchange fluids through alternate plates. Turbulizers in the form of half-height shim plates are located between the plates. The shim plates have central portions defining flow augmentations extending from one side of the plates only, and the plates have peripheral edge portions that are coterminous with the respective continuous ridges raised peripheral flanges.
