A water cooling panel forms a part of or substitute for the wall of a metallurgical furnace, such as an electric arc furnace, LF furnace, VOD, AOD furnace. These industrial furnace parts can be formed alternately as tube type coolers formed of parallel pipes connected at its ends in headers, with the latter having internal baffles to define a serpentine path, or as box type coolers formed of steel plates or sheet and having internal baffle plates defining a serpentine path for the cooling fluid. In either case, fluid orificies are provided to permit a minor amount of flow through the baffles or baffle plates where there is a direction change in the serpentine flow path. This serves to prevent stagnation and prevent the problems of hot spots and steam bubbles where there is a change of direction in the cooling flow. Projections welded along the furnace-facing side of the panel permit the panel to be covered with a layer of refractory material or solidified slag.
