DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples, but the examples are not as the limitation of the utility model.

[0020] The X-ray tube body 1 is installed in the X-ray tube mounting seat 5 inside the protective shell 3, and the protective shell 3 is provided with a cover plate 4 on the left and right sides. The cover plate 4 is connected with the protective shell 3 through a hinge, so that the cover plate 4 can be flexibly opened and closed relative to the protective shell 3, facilitating the installation, inspection, maintenance and other operations of the X-ray tube body 1 and its accessories inside the protective shell 3. Moreover, a sealing rubber strip is arranged at the contact edge of the cover plate 4 and the protective shell 3, which can effectively prevent foreign matters such as dust and water vapor from entering the inside of the protective shell 3, and create a relatively clean and stable working environment for the X-ray tube body 1.

[0021] The outer side of the cover plate 4 is fixedly provided with a mounting plate 6. The mounting plate 6 is fixedly installed on the outer side of the cover plate 4, and mainly serves to facilitate the installation of the entire ceramic X-ray tube on a corresponding equipment frame or workbench, and provides a stable and reliable mounting interface to ensure the overall stability of the equipment during use.

[0022] The outer wall of the X-ray tube body 1 is wound with a spiral cooling coil 8. One end of the spiral cooling coil 8 is connected with a water inlet pipe 9, and the other end of the spiral cooling coil 8 is connected with a water outlet pipe 10. During work, the cooling medium (such as water) flows into the spiral cooling coil 8 from the water inlet pipe 9, absorbs the heat generated by the X-ray tube body 1 during the flow in the coil, and then flows out of the water outlet pipe 10 after being heated. Through the heat exchange principle, the X-ray tube body 1 is effectively cooled. This cooling method directly contacts the X-ray tube body 1, which can timely and efficiently remove the heat generated by the ceramic X-ray tube during work, so as to ensure the continuous and stable work of the X-ray tube in a suitable temperature environment and avoid damage or performance influence due to overheating.

[0023] The inside of the protective shell 3 is provided with a fixing sleeve 7, which is sleeved on the outer side of the X-ray tube body 1.

On the other hand, the fixing sleeve 7 can also isolate the direct contact between the X-ray tube body 1 and the protective shell 3 to a certain extent, prevent damage to the X-ray tube body 1 due to accidental collision, and have a buffering effect.

[0024] The protective shell 3 adopts a double-layer structure, the inner layer is a lead plate with a thickness of 1.5-3 mm, which is used for shielding X-ray radiation, and the outer layer is a stainless steel plate with a thickness of 2-4 mm, which provides structural strength and a protective appearance, the inner and outer layers are connected through laser welding, and the welding seam width is less than 0.5 mm; the protective shell 3 is in a whole cylindrical shape, with a diameter of 40-80 mm and a height of 80-150 mm, and the thickness of the lead plate is between 1.5-3 mm, which mainly functions to shield X-ray radiation, since X-rays have penetrating properties and are harmful to the human body, the lead plate can effectively block X-ray leakage to the external environment, thereby ensuring the safety of surrounding personnel and equipment. The thickness of the outer layer of the stainless steel plate is 2-4 mm, which not only provides sufficient structural strength for the whole protective shell 3, so that it can withstand certain external force impact, vibration and the like, but also shapes a protective appearance, so that the whole device is more solid, durable and beautiful. The inner and outer layers are connected through laser welding, and the welding seam width is less than 0.5 mm, which can ensure the tightness and firmness of the connection, and at the same time, minimize the influence of the welding seam on the protective effect and appearance, so that the protective shell 3 forms a whole protective structure body with good performance.

[0025] The outer surface of the protective shell 3 is sleeved with a plurality of heat dissipation protrusions 11, and the heat dissipation protrusions 11 are in a conical shape; the side wall of the protective shell 3 is uniformly provided with heat dissipation through holes 301, and the heat dissipation through holes 301 are circular with a diameter of 3-5 mm; the contact area of the protective shell 3 with the external air is increased, and according to the heat exchange principle, heat dissipation to the air is more favorable.
