SELF-ENCLOSING HEAT EXCHANGER WITH CRIMPED TURBULIZER

摘要

Self-enclosing heat exchangers are made from stacked plates having raised peripheral flanges on one side of the plates and continuous periphera l 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. Th e 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.
