<p>This plate heat exchanger with parallel and countercurrent flow of the heat-exchange fluids consists of a stack of a defined number of ribbed plates (4) of the same size, clamped against one another between two flanges (1, 2), the said plates having openings (5, 6, 7, 8) in their corners, defining, within the stack, ducts for respectively supplying and discharging the heat-exchange fluids. The plates are made of machined bulk graphite, previously impregnated with a waterproofing material, and especially a resin. <IMAGE></p> |
