Abstract:
In an X-ray examination arrangement having an X-ray source mounted at a gantry which is rotatable around a rotational axis, the improvement of a cooling arrangement for said X-ray source comprising:a first annular heat exchanger disposed at said gantry and in thermally conductive connection with said X-ray source, and rotatable around said rotational axis together with said gantry; a second annular heat exchanger disposed in a thermally conductive, annular path with said first heat exchanger, with said first heat exchanger transferring heat from said X-ray source to said second heat exchanger directly via said annular path, said second heat exchanger being stationary relative to said first heat exchanger; and a plurality of inter-engaging annular guide devices for guiding an airstream, generated by rotation of said first heat exchanger and heated at said first heat exchanger, from said first heat exchanger to said second heat exchanger.
