ABSTRACT:
An actively cooled device, such as a heat shield for a fusion reactor, includes elements (10) of a heat-resistant material, particularly graphite, each being provided with at least one recess having a circular cross section, particularly a groove (14), into which a cooling pipe (16) conducting a coolant is brazed directly and with surface contact. This produces an effective dissipation of heat from the elements and a more durable connection of the elements with the cooling pipe or pipes.
