Abstract
An x-ray tube has an anode plate connected to an anode tube that is mounted such that it can rotate around a rigid anode shaft. To improve the heat dissipation from the anode plate, a liquid for dissipation of heat to the anode shaft is accommodated in an intervening space formed between the anode shaft and the anode plate.
Claims15
An x-ray tube comprising:
- an anode plate attached to an anode tube, said anode plate being subject to heating during operation of the x-ray tube;
- a rigid anode shaft on which said anode tube is rotatably mounted by bearings, said anode shaft projecting into said anode plate with an intervening space formed between said anode shaft and said anode plate;
- a liquid that dissipates heat from said anode plate to said anode shaft disposed in said intervening space;
- and
- said anode tube having a first section surrounding said bearings and a second section extending from an end of said first section to said anode plate, said second section having a thinner tube wall than said first section to decrease heat flow from said anode plate to said first section of said anode tube.
