Abstract

An x-ray radiator has a rotating bulb tube whose vacuum housing rotates within the radiator housing filled with a fluid coolant, as well as with an external heat exchanger for the cooling of the coolant, with the coolant admission connector and the coolant discharge connector for the coolant conducted through the external heat exchanger without a circulating pump arranged at respective positions of the radiator housing at which a lower pressure and a higher pressure are generated by the rotation of the rotating bulb.
