ABSTRACT OF THE DISCLOSURE A cooling device is described for the wall structures or coverplates of furnaces and industrial furnaces and electric arc furnaces in particular. A plurality of cooling tubes disposed side by side with intermediate gaps, have elbow members welded on the tube ends. The flow channel for the cooling agent thus follows a serpentine or meandering path. The ends of the cooling tubes connected to the elbow members are expanded towards each other and the expanded sections are contiguous so that they define the intermediate gaps and are welded one to the next. Such elbow members are caps welded on the ends of the cooling tubes and thus form a united self-supporting assembly. An additional plate can be mounted, without welding to the tube assembly on the face away from the furnace space.
