The cooling channel is closed with respect to the chamber to prevent the cooling media from passing through the chamber outside the cooling channel The body forms the wall of a part of the cooling channel, and the cooling elements face the inner space of the cooling channel. The part of the cooling channel whose wall comprises the cooling body is arranged in a controlled movable way in the inner chamber.
