Abstract
A plate type heat exchanger is disclosed having flow passages extending beyond the area of heat transfer on at least one end. The extending ends of the flow passages serve as sacrificial inlets for flow of one of two fluids through the heat exchanger so that any leak resulting from flow erosion or from corrosion in the extending flow passages does not result in mixing of the two fluids.
