[0002] At present, in the welding process of various large-scale metal pipe production, the use of X-ray flaw detectors is indispensable. Its basic principle is that through the interaction between the anode head and the cathode head, the emitted electrons hit the anode target, exciting X-rays, and detecting the cracks and defects inside the pipe through the X-rays. However, the high-voltage packages and anode heads in current common X-ray generators are prone to heat generation. After working for a period of time, it is necessary to stop the machine for cooling for a period of time and then start the machine again. Such intermittent start-up and shutdown processes will obviously affect the working efficiency of the flaw detector. There is also a temperature reduction treatment for the anode head in the existing X-ray generators, but only some problems are solved, and the purpose of continuous working for a long time cannot be achieved. Therefore, it is necessary to improve the structure of this kind of ray generator. Content of the Utility Model
