Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to an X-ray tube component device. Background Art

[0002] In the field of medical devices, X-ray tube components have been widely used, and are widely used in X-ray machines, X-ray imaging systems, CT scanners, etc. A typical X-ray tube component generally consists of a tube, an anode high-voltage plug, a cathode high-voltage plug, an X-ray tube, etc. The anode high-voltage plug and the cathode high-voltage plug are arranged on both sides of the tube shell. The X-ray tube of the X-ray machine is fixed in the middle section of the inner part of the tube shell. When the tube works, a large amount of heat will be generated. A lead layer is attached to the inner wall of the tube shell to prevent radiation. The tube adopts a sealed structure, and insulating oil is filled inside for insulation and heat dissipation.

[0003] However, in the above-mentioned typical design scheme of the existing X-ray tube component, since the tube shell is a closed structure and the inner wall is coated with a lead layer to prevent radiation, and the thermal conductivity of lead is poor, the heat inside the tube shell cannot be dissipated in time, and the fluidity of the internal insulating oil is poor, which may lead to uneven distribution of internal heat, resulting in a large temperature difference between the vicinity and periphery of the focal point, such as causing too high local temperature of the anode, thus causing the target surface to melt and crack, reducing the service life of the device; at the same time, since the temperature inside the tube shell cannot be dissipated in time, the temperature inside the tube shell increases rapidly, which will cause a temperature alarm, resulting in equipment shutdown, blurred imaging or even component damage, reducing the service life of the tube, and it takes at least 30 to 60 minutes to continue working after shutdown, affecting the normal operation and working efficiency of the X-ray tube component, and even affecting the medical operation process; at the same time, since the temperature inside the tube shell cannot be dissipated in time, the heat capacity of the existing tube design scheme reaches the bottleneck of use and cannot meet the application requirements of high-frequency long-duration diagnosis in the medical system. Summary of the Invention

[0026] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Such as Figures 1 to 8As shown in the figure, an embodiment of the present application provides an X-ray tube assembly device. The X-ray tube assembly device includes a tube housing 10, an anode high-voltage plug 201, a cathode high-voltage plug 202, and an X-ray tube 203 disposed within the tube housing 10. The tube housing 10 is hermetically sealed, and insulating oil is filled inside the tube housing 10 for insulation.

[0028] Specifically, the X-ray tube assembly device further includes a fluid circulation device disposed outside the tube housing 10. The inlet (i.e., the first inlet 21) and the outlet (i.e., the first outlet 22) of the fluid circulation device can be respectively connected to the outlet (i.e., the tube housing outlet 12) and the inlet (i.e., the tube housing inlet 11) of the tube housing 10 through a first oil pipe 31 and a second oil pipe 32. The tube housing inlet 11 and the tube housing outlet 12 communicate with the insulating oil filled inside the tube housing 10. The fluid circulation device can be specifically set as a circulation pump 20, and the fluid circulation device can be specifically fixed on the side wall of the tube housing 10 by bolts. In this way, when the fluid circulation device starts to work, the insulating oil inside the tube housing 10 can circulate through the fluid circulation device, improving the oil fluidity inside the tube housing 10, making the insulating oil evenly distributed, and making the heat distribution inside the tube housing 10 uniform.

[0029] More specifically, a radiation-proof heat extraction plate 14 is attached inside the tube housing 10, and a plurality of openings 15 are formed in the middle of the tube housing 10, and each of the openings 15 leads to the radiation-proof heat extraction plate 14. The X-ray tube assembly device further includes a heat dissipation assembly disposed outside the tube housing 10, which includes a heat sink assembly attached to the outer surface of the middle part of the tube housing 10 and a plurality of heat pipes. The heat extraction ends of each heat pipe are hermetically inserted into the openings 15 on the tube housing 10 and are connected to the radiation-proof heat extraction plate 14 inside the tube housing 10 for heat extraction, and the heat dissipation ends of each heat pipe are inserted into the heat sink assembly for heat dissipation. The gaps of the openings can be sealed by welding processes, etc.

[0030] Since the heat conduction medium of the existing X-ray tube assembly device is insulating oil, and the heat conduction performance of the oil is poor and the heat dissipation effect is bad, in the embodiment of the present application, heat can be extracted quickly and efficiently through each heat pipe and the radiation-proof heat extraction plate 14. The heat pipe realizes efficient heat transfer through a phase change cycle, not only has high heat conduction performance, can realize rapid heat conduction and heat dissipation, but also has advantages such as light weight, high temperature uniformity, no external power required, strong adaptability, flexible direction, wide applicable temperature range, high compactness, and long service life.

[0031] Compared with the prior art, the X-ray tube assembly device provided by the embodiment of the present application is provided with a fluid circulation device outside the tube housing 10, and the inlet and outlet of the fluid circulation device are respectively communicated with the outlet and inlet of the tube housing 10. When the fluid circulation device starts to work, the insulating oil in the tube housing 10 can circulate through the fluid circulation device, improving the fluidity of the oil inside the tube housing 10, making the insulating oil evenly distributed, and making the heat distribution inside the tube housing 10 uniform; and a radiation-proof heat-taking plate 14 is attached to the inner wall of the tube housing 10 for heat-taking inside the tube housing 10, and a plurality of openings 15 are formed in the middle of the tube housing 10, and each of the openings 15 leads to the radiation-proof heat-taking plate 14; a heat dissipation assembly is also provided outside the tube housing 10, which includes a heat sink assembly attached to the outer surface of the middle of the tube housing 10 and a plurality of heat pipes. The heat-taking ends of each heat pipe are hermetically inserted into the openings 15 on the tube housing 10 and are connected to the radiation-proof heat-taking plate 14 inside the tube housing 10 for heat-taking, and the heat dissipation ends of each heat pipe are inserted into the heat sink assembly for heat dissipation. The heat conduction efficiency is improved, enabling it to transfer the heat generated inside the tube housing 10 to the heat dissipation end at a faster speed, effectively reducing the temperature peak of the core components inside the tube.

[0032] With such a setting, not only can the insulating oil inside the tube housing 10 circulate, improving the oil fluidity and making the heat distribution more uniform, but also the heat-taking ends of each heat pipe can be inserted into the radiation-proof heat-taking plate 14 attached to the inner wall of the tube housing 10 for heat-taking, and the heat inside the tube housing 10 can be dissipated in time through the heat dissipation ends of each heat pipe inserted into the heat sink assembly, solving the problem that the heat inside the tube housing 10 cannot be dissipated in time, increasing the heat capacity of the X-ray tube assembly device, prolonging the continuous working duration of the X-ray tube assembly device, shortening the duty cycle, increasing the service life, and at the same time solving the problem that the existing solutions cannot meet the high-frequency long-duration diagnostic application requirements of the medical system; effectively preventing the problem of the target surface melting and cracking caused by local overheating, reducing the service life of the equipment; and the problem of temperature alarm caused by local overheating, resulting in equipment shutdown, blurred imaging or even component damage, reducing the service life of the tube and affecting the normal operation process and operation efficiency; and the good heat dissipation effect can reduce the imaging instability problem caused by overheating of the X-ray tube, improving the clarity and quality of imaging.

[0033] A specific embodiment is, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the two sides of the tube shell 10 have a first anode mounting shell 131 and a second cathode mounting shell 132 for sealing and covering the anode high-voltage plug 201 and the cathode high-voltage plug 202, respectively. The tube shell inlet 11 and the tube shell outlet 12 can be respectively arranged on the side walls of the first anode mounting shell 131 and the second cathode mounting shell 132. Preferably, the shape of the first anode mounting shell 131 and the second cathode mounting shell 132 can be similar to a cylinder extending in the transverse direction. And the heat sink assembly and the fluid circulation device can be arranged at the top and side between the first anode mounting shell 131 and the second cathode mounting shell 132, that is, the top and side of the middle part of the tube shell 10.

[0034] Due to the arrangement of the anode high voltage plug 201 and the cathode high voltage plug 202 of the X-ray tube assembly device, they are generally located farther away from the centrally arranged X-ray tube 203, and are generally located at a more peripheral position, so the radiation will be less. The tube shell inlet 11 and the tube shell outlet 12 are arranged on the first anode mounting shell 131 and the second cathode mounting shell 132, which can reduce the radiation leakage as much as possible and ensure the overall sealing.

[0035] A preferred embodiment is as follows Figures 1 to 8 As shown, the heat dissipation assembly of the X-ray tube assembly device provided in the embodiment of the present application may also include a heat dissipation fan 71 and a fan bracket 72 for installing and fixing the heat dissipation fan 71. Specifically, the heat dissipation fan 71 can be connected and fixed to the fan bracket 72 by bolts. The fan bracket 72 is mounted, connected and fixed to both sides of the heat sink assembly. Specifically, the fan bracket 72 can be connected and fixed to the heat sink assembly by bolts, and the bottom of the heat dissipation fan 71 is attached to the upper surface of the heat sink assembly, and the air outlet direction of the heat dissipation fan 71 is upward, so that the air around the heat sink assembly can flow quickly, forced air cooling, accelerated heat dissipation, and further improved heat dissipation efficiency.

[0036] Furthermore, a temperature sensor may be built into the tube shell 10, and the temperature sensor is electrically connected to the aforementioned circulation pump 20 and the cooling fan 71. When the temperature inside the tube shell 10 is too low, lower than the preset normal working temperature range, the circulation pump 20 and the cooling fan 71 are turned off, or the working power of the circulation pump 20 and the cooling fan 71 is lowered, the flow speed of the oil is slowed down, the energy consumption is reduced, the fan is stopped, and unnecessary energy consumption is reduced; when the temperature inside the tube shell 10 is too high, higher than the preset normal working temperature range, the working power of the circulation pump 20 and the cooling fan 71 is increased, the flow speed of the oil is accelerated, the heat dissipation efficiency is improved, the fan speed is increased, the air flow is strengthened, and the heat dissipation effect is improved.

[0037] Implement flexible AI intelligent dynamic temperature control. Real-time monitor the temperature distribution of the tube by temperature sensors, combine with AI algorithms to predict the change of heat load, and dynamically adjust the working modes of the heat dissipation module (circulation pump 20 and cooling fan 71), such as liquid cooling flow rate and fan speed, to achieve precise temperature control and energy consumption optimization. Specifically, automatically adjust the working power of the circulation pump 20 and the cooling fan 71 according to the temperature change in the tube shell 10, ensure the efficient operation of the heat dissipation circulation system of the X-ray tube assembly device, while also saving energy and reducing consumption, optimizing resource utilization, extending the service life of the equipment, preventing overheating risks, and improving safety; it can also rationally design and utilize the duty cycle during the diagnosis interval of the patient diagnosis device to achieve non-operation during the diagnosis time.

[0038] In a preferred embodiment, the X-ray tube assembly device provided by the embodiment of the present application is an integrally formed structure. Specifically, the externally connected fluid circulation device and the heat dissipation component are integrally formed with the tube shell. Specifically, components such as the heat dissipation component, heat pipe, and circulation pump 20 can be highly integrated, and the redundant structure can be reduced through optimized design to reduce the weight of the module.

[0039] With such a setting, on the one hand, the structure of the X-ray tube assembly device can be made more compact, all components are tightly integrated together, reducing the volume occupied by the overall equipment, saving space, simplifying the installation process, reducing the installation time and the complexity of installation operations, and improving the convenience of maintenance; on the other hand, it can also enhance the sealing performance and achieve a more efficient heat conduction path. The integrally formed structure components are easier to achieve a good sealing effect, reducing the risk of leakage. The integrally formed structure can also ensure that heat is transferred to the heat sink structure more directly and efficiently, improving the heat dissipation efficiency.

[0040] Moreover, the X-ray tube assembly device provided by the embodiment of the present application can support high-power X-ray tubes. Through the modular interface design, it can realize the development and transformation of the existing low-thermal-capacity conventional products in the market, reduce the loss of relevant diagnosis and treatment resources for high-thermal-capacity products, increase economic benefits, and achieve the multiple utilization of medical resources.

The second heat extraction end section 621 is hermetically inserted into the shell 10 through the opening 15 of the shell 10 and is welded and fixedly attached to the anti-radiation heat extraction plate 14 inside the shell 10. The third connection section 623 passes through the opening 15 and the second heat dissipation end section 622 is inserted and embedded in the strip-shaped slots 531. The plurality of strip-shaped slots 531 are arranged in one-to-one correspondence with the plurality of U-shaped heat pipes 62.
