Monobloc cooling device component

The invention relates to a cooling device component having a through-hole for carrying coolant, which comprises at least one heat shield made from tungsten, a tungsten alloy, a graphitic material or a carbidic material.

Therefore, it is an object of the invention to provide a cooling device component of monobloc design (PFM heat shield with a through-hole) which suitably meets the demands resulting from both physical and mechanical stresses.

THE MAIN APPLICATION AREAS

• Construction of nuclear reactor components

THE MAIN INNOVATIVE ASPECTS AND ADVANTAGES

The cooling device component according to the invention ideally satisfies the multi-faceted and in some cases contradictory profile of requirements presented in the description and therefore represents a simple solution to a long-standing problem.
