Description

Technical Field

[0001] The utility model relates to the technical field of X-ray generators, in particular to a water-cooled X-ray generator. Background Art

[0002] X-ray generator is a special device that can generate X-rays. Since X-rays have the characteristics of penetrating, fluorescent and photographic effects, they can form images of objects on the detection medium. Since each object has different density and thickness, when X-rays penetrate different objects, the degree of X-ray absorption is different, so the amount of X-rays reaching the detection medium is different, forming images with different black and white contrasts, providing a basis for diagnosis in specific occasions.

[0003] The mechanism of X-ray generation is to use a high-voltage electric field in a vacuum environment to accelerate the electron source so that it bombards a suitable metal target surface. During the collision, the electrons suddenly decelerate, and the lost kinetic energy is released in the form of photons, forming a continuous part of the X-ray spectrum. The X-ray tube device is the main component for generating X-rays. In this process, because only about 1% of the electrical energy is converted into X-ray energy, more than 99% of the energy is converted into heat energy, the X-ray tube device will generate huge heat. This heat is useless and harmful. A good X-ray device not only needs to provide a stable high-voltage electric field and filament power supply, but also needs to ensure that the X-ray tube device has a good continuous working environment.

[0004] The mainstream technology on the market is to use an oil pump to pump the insulating oil that provides insulation protection and heat conduction to the oil radiator, and then use a fan to dissipate the heat and pump it back to its original place. The disadvantage of this technology is that when the power of the X-ray device is large, the heat dissipation effect will be greatly reduced, and because of the use of fans for heat dissipation, the ambient temperature requirements are extremely high, and the overall thermal efficiency is low, which makes the cooling environment provided by the X-ray tube device worse, affecting its overall life.

[0005] Therefore the prior art needs to be improved and enhanced. Utility Model Content

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the water-cooled X-ray generator provided by the utility model comprises an oil tank 1, in which an X-ray tube device 2 is arranged, and a circulating oil pump 3 and a liquid-cooled heat exchanger 4 are arranged on the oil tank 1, the circulating oil pump 3 is connected with a first oil inlet and a first oil outlet 6 for circulating insulating oil, the first oil inlet 5 is located inside the oil tank 1 and above the cathode 7 of the X-ray tube device 2, the liquid-cooled heat exchanger 4 is provided with a second oil inlet 8 and a second oil outlet 9 for circulating insulating oil, and a liquid inlet 10 and a liquid outlet 11 for circulating cooling liquid, the second oil inlet 8 is communicated with the first oil outlet 6 through a pipeline, the second oil outlet 9 is located inside the oil tank 1, and the second oil outlet 9 is located above the anode 12 of the X-ray tube device 2.

The insulating oil can be used to cool the X-ray tube device 2. The insulating oil in the oil tank 1 is sucked by the circulating oil pump 3. Since the X-ray tube device 2 generates a large amount of heat when working, the temperature of the insulating oil in the oil tank 1 will rise, that is, the high-temperature insulating oil will enter the circulating oil pump 3 through the first oil inlet interface 5, and then be pumped out from the first oil outlet interface 6.

The cooling process can enable the X-ray tube device 2 to still maintain a better working oil temperature in an extremely high temperature environment, thereby greatly improving the service life of the X-ray tube device 2.

[0042] Furthermore, if Figure 5 and Figure 6 As shown, the driving member 17 and the suction part 18 are both provided with auxiliary fixing holes 21, and the driving member 17 and the suction part 18 are fixed to the fixing member 14 through the auxiliary fixing holes 21. The auxiliary fixing holes 21 can make the assembly between the driving member 17 and the suction part 18 and the fixing member 14 more stable.

[0043] Furthermore, if Figure 5 and Figure 6 As shown, the fixing member 14 is provided with a positioning groove 22 which is adapted to the edge portion 19 . Through the positioning groove 22 , the driving member 17 can be quickly placed in a designated position for assembly with the fixing member 14 , that is, the positioning groove 22 effectively improves the assembly efficiency between the circulating oil pump 3 and the fixing member 14 .

[0044] Furthermore, if Figure 5 and Figure 6As shown, the suction part 18 includes a suction shell 23, the bottom of the suction shell 23 is provided with the first oil inlet interface 5, and the side of the suction shell 23 is provided with the first oil outlet interface 6.
