Abstract

A plate heat exchanger especially adapted for viscous fluids or fluids containing fibers has spacing means extending above the normal corrugations thus widening the normal interplate channels and the inlets and outlets to and from said channels are formed by juxtaposing the plates containing ports forming said inlets and outlets to give the maximum throughflow.
