Brief description of the drawings
Fig. 1 is the structural representation of the anti-coolant overheating vaporising device of X-ray machine described in this
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, so that those of ordinary skill in the art are with reference to implementing according to this after this description.
The boiling point of liquid coolant determines by fluid pressure, and static pressure is lower, and boiling point is lower, and liquid more easily evaporates.When X-ray machine work, X-ray tube rotates around system axis 2, and rotary centrifugal force acceleration is much larger than acceleration of gravity, and therefore fluid pressure depends on rotary centrifugal force.And certain some centrifugal force is directly proportional to this point and centre of gyration distance in rotary body, therefore the most close system axis also static pressure minimum in the output window region 3 under heat-flash load simultaneously, the trend that forms bubble for being suppressed at this region, the invention provides the anti-coolant overheating vaporising device of a kind of X-ray machine.
As shown in Figure 1, the anti-coolant overheating vaporising device of X-ray machine of the present invention, comprises fluid containment cavity, and liquid coolant is equipped with in its inside, keeps liquid road to be communicated with the coolant entrance pipeline of X-ray machine; The first container 7, is positioned at the top of described fluid containment cavity, and liquid heavy metal is equipped with in its inside, is preferably hydrargyrum.Described fluid containment cavity also comprises teleblem 5, between described fluid containment cavity and the first container 7, and between described fluid containment cavity and described the first container 7 at least part form movably piston; Base 6, is positioned at the bottom of described fluid containment cavity; Thin film 4, connects described teleblem 5 and base 6, and described teleblem 5 and thin film 4 are the thin film of flexibility and cooling fluid impermeable mechanically.Wherein, X-ray machine is exerted pressure to described liquid coolant at teleblem 5 described in system for winding axis 2 rotation processes, and liquid coolant enters cooling duct and carries out cooling to X-ray tube 1.Because containing hydrargyrum in the first container 7, so that quality becomes is large, the centrifugal force being applied on liquid coolant becomes large, and it is large that static pressure becomes, and improved the boiling point of described liquid coolant, prevent described X-ray tube 1 because of the vaporization of liquid coolant overheated.
The anti-coolant overheating vaporising device of described X-ray machine also comprises second container 8, and its bottom is connected by a flexible steel in flat section tubing 9 with the bottom of described the first container 7 and keeps liquid road to be communicated with; One fixed bar 11, described second container 8 is connected with described fixed bar 11 by bolt 10, and can move up and down with respect to described fixed bar 11; Driving mechanism 12 and control module, also comprise temperature inductor, is connected with described control module, the temperature of X-ray tube 1 is responded to, and signal transmission given described control module; Described control module receives the signal from temperature inductor, according to the temperature of X-ray tube 1, described driving mechanism 12 is controlled, and described driving mechanism 12 is connected with described second container 8 and drives described second container 8 to move up and down along described fixed bar 11; Described driving mechanism 12 is motor.
