ABSTRACT:
A plate heat exchanger comprising a separable pack of gasketed plates defining flow spaces between the plates and having port-forming apertures, the apertures in communication with the flow spaces being provided in the zones of communication with castellated strips to provide interplate support in the region of the gasket sealing the ports from the adjacent flow spaces, and the said sealing gaskets being housed in grooves having spaced reinforcing recesses on at least one wall, each said reinforcing recess being supported by a castellation of the strip and the spacing of the reinforcing recesses being such that one or more castellations is located between each pair of recess-supporting castellations. The invention further extends to single plates of such a pack.
