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.
