Abstract
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. Expanded metal turbulizers are located in the flow channels. The turbulizers have portions thereof crimped closed to control the flow inside the channels and prevent unwanted bypass flow.
