A cooling plate ( 1 ) made of copper or a copper alloy for blast furnaces has a plurality of bore holes ( 6 ) for accommodating a cooling medium. The bore holes ( 6 ) are connected to a cooling medium intake ( 12 ) and a cooling medium outlet via connecting pipes ( 9 ) that are welded onto the cold side of the plate ( 5 ). Connecting pipes ( 9 ), at their plate ends ( 14 ), are furnished with flanges ( 15 ) that are formed by being flanged open. These flanges ( 15 ) are set into recesses ( 17 ) in the cold side of the plate ( 5 ), and are welded at their circumference by V seams ( 19 ) to the cold side of the plate ( 5 ).
