Abstract
Finned anode. In one example embodiment, an anode suitable for use in an x-ray tube includes a hub, a front side, and a target surface disposed on the front side. The hub is configured to attach to a bearing assembly and the front side substantially faces the bearing assembly. The anode further includes a rear side substantially opposite the front side, as well as two or more annular anode fins extending from the rear side. The annular anode fins are positioned radially outward from the hub to an outer periphery of the rear side.
Claims20
A finned anode suitable for use in an x-ray tube, the anode comprising:
- a hub configured to attach to a bearing assembly;
- a front side substantially facing the bearing assembly;
- a target surface disposed on the front side;
- a rear side substantially opposite the front side;
- and
- two or more annular anode fins extending from the rear side, the annular anode fins being positioned radially outward from the hub to an outer periphery of the rear side.
An anode assembly suitable for use in an x-ray tube, the anode assembly comprising:
- a finned anode configured to be rotatably supported by a bearing assembly, the finned anode including:
- a front side including a target surface for receiving an electron stream, the front side substantially facing the bearing assembly,
- a rear side substantially opposite the front side, and
- two or more annular anode fins extending from the rear side;
- and
- a thermal plate including two or more annular plate fins configured to be interleaved with the annular anode fins.
An x-ray tube comprising:
- an evacuated enclosure;
- a cathode positioned within the evacuated enclosure and configured to produce an electron stream;
- a bearing assembly;
- a rotatable finned anode positioned within the evacuated enclosure, the rotatable finned anode including:
- a hub attached to the bearing assembly,
- a front side including a target surface for receiving the electron stream, the front side substantially facing the bearing assembly,
- a rear side substantially opposite the front side, and
- two or more annular anode fins extending from the rear side;
- and
- a thermal plate including:
- an inner side positioned within the evacuated enclosure,
- two or more annular plate fins extending from the inner side and interleaved with the annular anode fins, and
- an outer side substantially opposite the inner side, the outer side positioned outside the evacuated enclosure and configured to be proximate a liquid coolant.
The x-ray tube as recited in claim 14, the x-ray tube further comprising a coolant passageway positioned proximate the outer side and outside the evacuated enclosure, the coolant passageway configured to circulate a liquid coolant.
