Abstract: A cooling device component of monobloc design has a heat shield made from tungsten, a tungsten alloy, a graphitic material or a carbidic material provided with a through-hole. A cooling pipe for carrying coolant is joined in the through-hole. The heat shield is in turn joined or metallurgically joined to a structural part made from a material with a tensile strength at room temperature of >300 MPa and an electrical resistivity of >0.04 Ohm mm2m?1.

Abstract: A first-wall component for a fusion reactor contains at least one heat shield having a first region inclined toward the plasma and a second region lying opposite the first region and formed of a graphitic material. The heat shield has one or more slots that end in the first or second regions and are oriented generally in the direction of an axis of the cooling tube. The components suitably cope with the mechanical stresses resulting both from production and from thermal cycling.
