Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings, so that those of ordinary skill in the art can implement it after referring to this specification.
[0019] The boiling point of liquid coolant is determined by the static pressure of the liquid, the lower the static pressure, the lower the boiling point and the easier the liquid evaporates. When the X-ray machine is working, the X-ray tube rotates around the system axis 2, and the rotational centrifugal force acceleration is much greater than the gravitational acceleration, so the hydrostatic pressure depends on the rotational centrifugal force. The centrifugal force at a certain point in the rotating body is proportional to the distance between this point and the center of rotation. Therefore, the static pressure in the output window area 3, which is closest to the system axis and under strong thermal load, is the smallest. In order to suppress the tendency of air bubbl...
