Description

Technical Field

[0001] This utility model relates to the field of X-ray tube technology, specifically to an X-ray tube housing. Background Technology

[0002] An X-ray tube is a component used to generate X-rays, primarily used in medical equipment (CT scanners and X-ray machines, etc.). When used in a CT scanner, the X-ray tube rotates around the patient and emits X-rays to scan the patient. Currently, during installation, the anode end of the X-ray tube is typically fixed to the stator, which is then bolted into a housing. This housing is then installed in the corresponding position on the CT scanner. At this point, the cathode end of the X-ray tube is suspended. To improve the stability of the X-ray tube, a double-layered, interconnected plastic ring is usually placed over the cathode end, and then the plastic ring is fixed into the housing.

[0003] Existing X-ray tubes all use a cylindrical shell structure. When replacing them, they need to be removed from the end. However, the end is connected to the equipment. When replacing them, the entire X-ray tube needs to be removed from the equipment first, and then the end needs to be removed separately. This is cumbersome and cannot be done quickly. Therefore, a new type of X-ray tube shell is proposed. Utility Model Content

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] This utility model provides an outer shell for an X-ray tube, in which a movable shell is connected at a slot. The movable shell fits snugly into the slot, forming a closed circular outer shell. This fitted structure facilitates quick and easy installation and positioning. Furthermore, the side-opening design eliminates the need to remove the entire outer shell from the equipment during replacement, simplifying maintenance and use. Please refer to [link to relevant documentation]. Figures 1-4 It includes: a support shell 100 and a disassembly shell 200.

[0032] The support shell 100 includes a fixed shell 110, a slot 120, a first connecting post 130, a second connecting post 140, and a first connecting lug 150. The slot 120 is opened on the side wall of the fixed shell 110. The first connecting post 130 is provided at the left end of the fixed shell 110. The second connecting post 140 is provided on the rear side wall of the fixed shell 110. The first connecting lugs 150 are evenly distributed at the slot 120.

[0033] The fixed housing 110 is a hollow cylinder with a slot 120 cut in half on the side wall. The first connecting post 130 and the second connecting post 140 are both connected to the interior of the fixed housing 110.

[0034] The disassembly shell 200 is set on the slot 120. The disassembly shell 200 includes a movable shell 210, a window 220, and a second connecting ear 230. The movable shell 210 is fitted into the slot 120. The window 220 is provided on the side wall of the movable shell 210. The second connecting ear 230 corresponding to the first connecting ear 150 is provided at the opening of the movable shell 210.

[0035] The movable housing 210 adopts a semi-circular housing structure. The movable housing 210 is fitted and connected with the slot 120. The fitted connection method facilitates quick connection and positioning. After connection, the second connecting ear 230 is aligned with the first connecting ear 150 for subsequent fastening connection.

[0036] An X-ray tube 160 is provided at the left end of the inner cavity of the fixed housing 110. The connecting wires of the X-ray tube 160 pass through the first connecting post 130 and the second connecting post 140 respectively, and are used to connect cables.

[0037] To form a closed shell, after the movable shell 210 is connected to the slot 120, a closed cylinder is formed between the fixed shell 110 and the movable shell 210.

[0038] Since heat dissipation is required during operation, a cooling mechanism 300 is provided at the right end of the inner cavity of the fixed housing 110. Specifically, the cooling mechanism 300 includes a sealing plate 310, a cooling box 320, a ventilation duct 330, and a fan 340. The sealing plate 310 is fitted into the right end of the inner cavity of the fixed housing 110. A ventilation duct 330 is provided inside the cooling box 320. Both ends of the ventilation duct 330 pass through the left end of the sealing plate 310 respectively. A fan 340 is provided on the ventilation duct 330 outside the cooling box 320.

[0039] The fan 340 drives airflow through the ventilation duct 330, causing the airflow to circulate between the outside of the X-ray tube 160 and the ventilation duct 330. As the airflow circulates, it carries away the heat from the outside of the X-ray tube 160. The cooling box 320 contains coolant to cool and dissipate heat from the airflow circulating in the ventilation duct 330.

[0040] Due to prolonged use, the coolant temperature will rise, affecting the cooling effect. Therefore, a refrigeration component 400 is provided on the side wall of the cooling box 320. The refrigeration component 400 includes a semiconductor refrigeration chip 410 and a heat-conducting fin 420. The refrigeration end of the semiconductor refrigeration chip 410 is connected to the evenly distributed heat-conducting fins 420, and the heat-conducting fins 420 are inserted into the inner cavity of the cooling box 320.

[0041] The semiconductor refrigeration chip 410 is located outside the cooling box 320. The temperature of the cooling end of the semiconductor refrigeration chip 410 is reduced by the heat-conducting fins 420 to cool the internal coolant, thus ensuring the cooling effect.

[0042] Since circulating dust can affect the performance of the X-ray tube, a filter element is installed at the air inlet of the ventilation duct 330. The filter element uses an activated carbon filter to purify and filter the airflow.

[0043] To ensure a secure connection and prevent the structure from falling apart, both the first connecting ear 150 and the second connecting ear 230 have connecting holes with bolts inside to secure the structure.

[0044] Because radiation protection and sealing are required, a sealing gasket is provided at the connection gap between the fixed housing 110 and the movable housing 210 to improve the sealing effect.

[0045] The thermally conductive fins 420 use insulated fins to prevent leakage.

[0046] In practical use, the movable housing 210 is fitted into the slot 120. This fitted connection facilitates quick connection and positioning. After connection, the second connecting ear 230 is aligned with the first connecting ear 150 for subsequent fastening. The fan 340 drives airflow through the ventilation duct 330, allowing the airflow to circulate between the outside of the X-ray tube 160 and the ventilation duct 330. During airflow circulation, the heat outside the X-ray tube 160 is carried away. The cooling box 320 contains coolant to cool and dissipate heat from the airflow circulating in the ventilation duct 330. The cooling component 400 adopts a modular structure, which facilitates overall replacement. The cooling end temperature of the semiconductor cooling chip 410 is cooled by the heat-conducting fins 420 to cool the internal coolant, ensuring the cooling effect.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
