Abstract
A potshell for an electrolytic cell for the electrolytic reduction of aluminum includes a bottom plate, side walls and end walls of steel plates, and also a reinforcing structure surrounding structure. Up against the side walls and end walls, on the outside thereof are disposed vertical stiffeners and outside these stiffeners there is disposed an essentially horizontal reinforcing frame in such a manner that between the stiffeners there are formed vertical, free air passages up against the side walls and the end walls, and in such a manner that the stiffeners act as cooling ribs for conducting and dissipiating the heat from the side walls and the end walls.
