A heat exchanger system for a single-tank x-ray generator of an x-ray diagnostic device with a rotating anode tube with a glass jacket is provided. The system provides for the thermal radiation emitted by the anode plate of the rotating anode tube, which glows during load operation, to be absorbed in very close proximity to the tube by a heat exchanger with a window for the exiting x-ray radiation beam, without causing other components inside the generator tank to be heated by the thermal radiation. The heat exchanger preferably includes the lead shield required to shield against x-ray back-radiation and has a cooling agent flowing through it. The layer of insulating oil present in the space between the rotating anode tube and the heat exchanger is exchanged by means of a pump against insulating oil from other areas of the tank so as to prevent local overheating of the insulating oil in the gap.
