Description

Technical Field

[0002] A flaw detector is a non-destructive testing device that is specifically used to detect surface and internal defects of materials. It is widely used in industrial fields such as shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation and construction to ensure product quality and safety. The flaw detector uses electromagnetic, ultrasonic, penetrant and other technologies to non-destructively detect defects inside the object being tested, such as cracks, inclusions, fragmentation, pores, etc. According to different uses, flaw detectors can be divided into many types, such as X-ray flaw detectors, magnetic particle flaw detectors and Y-ray flaw detectors.

[0003] Traditional X-ray tubes generate a lot of heat during operation. Generally, a circulation tube is arranged on the X-ray tube to connect the air inlet tube with an external wind source device. The external wind source transmits wind to the circulation tube through the air inlet tube. In the circulation tube, the heat of the X-ray tube is transmitted to the air, and then the heat is brought to the outside of the X-ray tube through the air outlet pipe through the flow of wind to dissipate, thereby completing the entire heat dissipation process. However, this heat dissipation method cannot further cool the air entering the circulation tube, thereby reducing the heat dissipation effect and efficiency of the X-ray tube. Utility Model Content
