1 results about "X ray irradiation" patented technology

The utility model discloses a heat dissipation formula X ray tube, it includes glass shell, glass shell one end is provided with cathode assembly, glass shell one end is provided with anode assembly, and cathode assembly generates free electron through thermionic emission process, and anode assembly absorbs free electron and generates X ray, and glass shell outside fixedly connected with metal protective housing, and the metal protective housing bottom is provided with the through slot, and the electromagnetic coil is activated and produces the rotation magnetic field and gives birth to permanent magnet and drives target block rotation, and the electron that tungsten wire emits spreads to the larger area, and the heat capacity of X ray tube is increased significantly, and the insulating oil carries out heat exchange first during tungsten wire heating process, and simultaneously, the anode tube drives second bevel gear rotation, and the cooperation of second bevel gear and first bevel gear drives second pulley rotation, and under the action of transmission belt, the fan blade produces the downward airflow, and the airflow is discharged from the air outlet and carries out the cooling of insulating oil, and the inclined plane air deflector changes the wind direction, prevents the hot airflow and directly blows to the X ray irradiation place.
