The cathode cover plate 12 is provided with heat dissipation fins 13, and the heat dissipation fins 13 are used for increasing the heat dissipation area of the pipe sleeve 1 and improving the heat dissipation effect. The anode end 200 of the working assembly 2 is disposed adjacent to the anode cover plate 11 and the cathode end 201 of the working assembly 2 is disposed adjacent to the cathode cover plate 12.

The working assembly 2 includes an X-ray tube 20 and a stator coil 21, the stator coil 21 being wrapped around the X-ray tube 20.

Cooling module 3 includes cooling pump 30, honeycomb duct 31, control panel 33 and connecting piece 34, and cooling pump 30 is fixed to be set up on positive pole apron 11, and is concrete, and cooling pump 30 is oil-immersed water pump and fixes on positive pole apron 11 through the screw.
