Cooling component and method for producing the same

A cooling component having an, in particular, elongated, coated, cooling body made of metal or a metal alloy, aluminum, with which an object may be cooled, wherein the cooling body has one or more, parallel, elongated and/or linear medium channels for the throughflow of cooling medium, and having a connection part, which is connected to the cooling body in a fluid-tight manner and via which the cooling medium can be supplied to the cooling body and/or via which the cooling medium can be discharged from the cooling body, wherein the connection part is made from plastic, formed as a plastic injection molded part, wherein, to connect the connection part to the cooling body, a first, terminal, connecting region of the cooling body, which has a plurality of connecting faces, each with three-dimensional nanostructures and/or microstructures incorporated, by physical and/or chemical nanostructuring or microstructuring methods, is incorporated in the receiving space of a receptacle of the connection part and is connected to the receptacle there in a fluid-tight manner in that each connecting face of the cooling body is opposite a respectively associated connecting face of the receptacle and is pressed together with this.
