C-Arm dives power point system heat and cold

13. Heating the x-ray tube
X-ray tube is heated using a heating file surrounding the
cathode pipe. The heating file consists of an resistant
wire is connected to a high voltage electric current. The
passage of power across the heating file leads to heat
generation, leading to cathode heating to high
temperature.
X-ray tube is heated to a temperature ranging
from 2000 and 3000

18. The air cooling system consists of
several parts, including:
Cooling fan: It is responsible for
circulating air around the anode.
Cooling burner: a device that converts
air into steam.
Water tank: It is a tank in which water is
stored

19. Cooling using gases
Gas cooling is accomplished by circulating cold gas
through the anode. The gas transfers heat from the
anode to the outside
,where it is evaporated by a condenser
