Abstract
An equipped forced-convection housing unit for a rotating-anode X-ray tube comprises a flow-initiating device which is integrated in the housing unit and has the function of circulating the coolant fluid surrounding the X-ray tube. This arrangement simplifies the problems relating to supply of electric power to the motor which drives the flow-initiating device and the motor which drives the anode of the X-ray tube in rotation.
Claims24
An X-ray assembly comprising:
- (a) a housing having an inlet and an outlet;
- (b) an external circulation system coupled to said inlet and to said outlet for circulating a cooling fluid through said housing during use of the assembly;
- (c) an envelope disposed in said housing;
- (d) a first motor comprising a first stator disposed in said housing outside said envelope and a first rotor electrically coupled to said first stator, said first rotor being disposed in said envelope and being concentric to a longitudinal axis;
- (e) an anode disposed in said envelope and mechanically coupled to said first rotor for rotation about said longitudinal axis;
- and
- (f) a flow-initiating device disposed in said housing outside said envelope, said flow-initiating device comprising:
- (i) a second motor comprising a second stator disposed in said housing outside said envelope and a second rotor electrically coupled to said second stator, said second rotor being disposed in said housing outside said envelope and being concentric to said longitudinal axis, and
- (ii) a fluid driving means mechanically coupled to said second rotor for rotation about said longitudinal axis.
