摘要

Cooling element comprises a region (8) through which the coolant passes with an arrangement of internal coolant-conveying channels (9) which open out into tubular pieces (3, 4) connected to the cooling element; and edge regions. Each coolant-conveying channel extends via a mouth region of the tubular pieces into the edge region of the cooling element and has a cross-section with a guiding element (14) for guiding the coolant into the edge region of the cooling element and recycling against the flow direction. Preferred Features: The edge region of each cooling section (13) is formed as a separate end piece with the guiding element which is fixed to the base body guiding the cooling channel. The end piece is formed as a cast part or welded construction and is welded to the base body.
