SELF-ENCLOSING HEAT EXCHANGERS

摘要

Self enclosing heat exchangers are disclosed which 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 flow ports that line-up in the stacked plates to form manifolds for the flow of heat exchange fluids through alternate plates. Rib and groove barriers are formed in the plates inside the peripheral flanges and ridges. The barriers prevent short circuit flow on one side of the plates and promote flow to remote areas on the other side of the plates, to improve the overall efficiency of the heat exchangers.
