The invention relates to a monoblock cooling device component. A thermal shield that is made of tungsten, a tungsten alloy, a graphitic material, or a carbidic material is provided with a passage into which a cooling pipe is inserted in an integrally joined manner in order to conduct coolant. The thermal shield is integrally joined to a structural part that is made of a material having a tensile strength > 300 MPa at room temperature and a specific electric resistance > 0.04 ohm mm 2 m-1. |
