PLATE HEAT EXCHANGER WITH APERTURES IN WALL SIDES TO PRODUCE TURBULENCE

摘要

A plate heat exchanger composed of a plurality of plates (1), preferably made from sintered ceramic material, in which fluid-flow guide channels (2) are formed as a system of channels in such a way that a substantially meandering profile of the fluid flow is obtained over the surface area of the respective plate, the side walls (3) of the guide channels (2) having a plurality of apertures (4), which lead to turbulence of the fluid flow. A method for the production of such a plate heat exchanger, in particular by a diffusion welding process in which the plates are joined to form a seamless monolithic block. The plate heat exchanger is suitable in particular for applications at high temperatures and/or with corrosive media, and also as reactors.
