A cooling plate () made of copper or a copper alloy for blast furnaces has a plurality of bore holes () for accommodating a cooling medium. The bore holes () are connected to a cooling medium intake () and a cooling medium outlet via connecting pipes () that are welded onto the cold side of the plate (). Connecting pipes (), at their plate ends (), are furnished with flanges () that are formed by being flanged open. These flanges () are set into recesses () in the cold side of the plate (), and are welded at their circumference by V seams () to the cold side of the plate ().
