Description

Technical Field

[0001] The utility model relates to the technical field of X-ray tube fixing structures, in particular to an X-ray tube fixing structure. Background Art

[0002] An X-ray tube is a vacuum electronic device used to generate X-rays. It is widely used in medical, industrial, and scientific research fields. X-ray tubes are mainly composed of a cathode, an anode, and a glass or ceramic shell. The cathode emits electrons, and the anode receives electron bombardment. When a high voltage is applied between the cathode and the anode, the electrons are accelerated to collide with the anode target, generating X-rays. X-ray tubes can be divided into gas-filled tubes and vacuum tubes according to the way they generate electrons. The latter is more commonly used. According to their uses, they can be divided into medical X-ray tubes and industrial X-ray tubes. The medical field is mainly used for fluoroscopy and photography, while the industrial field is used for non-destructive testing. The global X-ray tube market size continues to grow and is expected to reach US$2.442 billion in 2030. Market drivers include the demand for high-precision imaging in the medical field and the demand for non-destructive testing technology in the industrial field;

[0003] Publication No. CN218160267U discloses a novel X-ray tube mechanism comprising an X-ray tube body and a base plate. A cooling mechanism and a clamping mechanism are provided on the upper surface of the base plate. An anode plate is fixed to the upper surface of the base plate. The cooling mechanism comprises a water tank and a water pump fixed to the upper surface of the base plate. A fixing plate is fixed to the upper surface of the water tank. Multiple fans and two second fixing brackets are fixed to the left side of the fixing plate. In this novel X-ray tube mechanism, a water pump draws coolant from the housing through the cooling mechanism. The coolant enters the cooling pipe through a first water pipe, dissipating heat from the X-ray tube body. After the coolant enters the second water pipe, it is cooled by the fan and finally enters the housing, facilitating recycling and dissipating heat from the X-ray tube body. This helps cool the heat generated by the X-ray tube during operation, preventing excessive temperatures from affecting the operation of the X-ray tube and thereby increasing the service life of the X-ray tube.

[0004] In order to solve the problem of using the X-ray tube in the above-mentioned technical solution, the existing technology adopts a cooling mechanism. A water pump draws coolant from the box and enters the cooling pipe through a first water pipe to dissipate heat from the X-ray tube body. After the coolant enters the second water pipe, it is cooled by a fan and finally enters the box for convenient recycling and dissipation of heat from the X-ray tube body. However, the X-ray tube is inconvenient to fix, which leads to the problem of insufficient convenience in fixing the X-ray tube. Utility Model Content
