Description

Technical Field

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

[0002] In the field of medical equipment, X-ray tube assemblies have been widely used, and are widely used in X-ray machines, X-ray imaging systems, CT scanners, etc. A typical X-ray tube assembly 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 inside the tube shell. When the tube works, a large amount of heat is generated. A lead layer is pasted on 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 existing design scheme of the above-mentioned typical X-ray tube assembly, since the tube shell is a closed structure and a lead layer is applied to the inner wall to prevent radiation, and the thermal conductivity of lead is poor, the heat inside the tube shell cannot be dissipated in time, resulting in uneven distribution of internal heat, a large temperature difference near and around the focus. For example, it will cause the local temperature of the anode to be too high, resulting in melting and cracking of the target surface, reducing the service life of the equipment; 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 assembly, 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 use bottleneck and cannot meet the application requirements of high-frequency long-duration diagnosis in the medical system.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0062] The following will describe in detail some embodiments of the present application in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0063] As Figures 1 to 4 shown, the embodiment of the present application provides an X-ray tube assembly device. The X-ray tube assembly device includes a tube housing 10 and an anode high-voltage plug 201, a cathode high-voltage plug 202, and an X-ray tube 203 disposed inside the tube housing 10, and the tube housing 10 is hermetically provided.

[0064] Specifically, the X-ray tube assembly device further includes a water-cooled heat exchange assembly. The water-cooled heat exchange assembly may include a water-cooled heat exchange tube 30 disposed inside the tube housing 10, a water-cooled radiator structure 40 disposed outside the tube housing 10, and a fluid circulation device. The fluid circulation device may specifically be a circulation pump 20, and the fluid circulation device may specifically be fixed to the side wall of the tube housing 10 by bolts.

[0065] Specifically, the inlet (i.e., the first inlet 21) and the outlet (i.e., the first outlet 22) of the fluid circulation device may be respectively communicated with the outlet (i.e., the tube housing outlet 12) of the tube housing 10 and the inlet (i.e., the third inlet 41) of the water-cooled radiator structure 40. The outlet (i.e., the third outlet 42) of the water-cooled radiator structure 40 is communicated with the inlet (i.e., the tube housing inlet 11) of the tube housing 10, and the tube housing inlet 11 and the tube housing outlet 12 are communicated with the inlet (i.e., the second inlet 31) and the outlet (i.e., the second outlet 32) of the water-cooled heat exchange tube 30.

[0066] With such a setting, when the fluid circulation device starts to work, driven by the fluid circulation device, the refrigerant inside the water-cooled radiator structure 40 outside the tube housing 10 and inside the water-cooled heat exchange tube 30 inside the tube housing 10 circulates inside and outside. The refrigerant may specifically be a water-cooling liquid. When the refrigerant flows in the water-cooled heat exchange tube 30 inside the tube housing 10, it absorbs the heat inside the tube housing 10 and is circulated out through the radiator to the water-cooled radiator structure 40 outside the tube housing 10 for heat dissipation, thereby dissipating the heat inside the tube housing 10 in time, realizing the cooling and heat exchange inside the tube housing 10, improving the heat conduction efficiency, enabling it to transfer the heat generated inside the tube housing 10 at a faster speed, effectively reducing the temperature peak of the core components inside the tube, and solving the problem that the heat inside the tube housing 10 cannot be dissipated in time; it also increases the heat capacity of the X-ray tube assembly device, extends the continuous working duration of the X-ray tube assembly device, shortens the duty cycle, increases the service life, and at the same time solves the problem that the existing solutions cannot meet the high-frequency long-duration diagnostic application requirements of the medical system; it also effectively prevents 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, and 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 and improve the clarity and quality of imaging.

[0067] Specifically, the water-cooled heat exchange tube 30 may be a water-cooled heat exchange copper tube made of copper material. Because copper has an extremely high thermal conductivity, good heat transfer and heat absorption effects, it can quickly transfer heat, significantly reduce the working temperature inside the tube housing 10, and has a fast heat dissipation speed.

[0068] In a preferred embodiment, the X-ray tube assembly device provided in the embodiments of the present application may be an integrally formed structure. Specifically, the externally connected fluid circulation assembly and the heat dissipation assembly are integrally formed with the tube shell, which is highly integrated. By optimizing the design, redundant structures are reduced, and the weight of the module is reduced. 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 closely integrated together, the volume occupied by the overall device is reduced, space is saved, the installation process can be simplified, the installation time and the complexity of installation operations are reduced, and the maintenance convenience can also be improved. On the other hand, the sealing performance can be enhanced and a more efficient heat conduction path can be achieved. The integrally structured components are easier to achieve a good sealing effect and reduce the leakage risk. The integrally structured can also ensure that heat is transferred to the heat sink structure more directly and efficiently, improving the heat dissipation efficiency.

[0069] Moreover, the X-ray tube assembly device provided in the embodiments of the present application can support high-power X-ray tubes. Through the modular interface design, it is possible to develop and transform the existing low-heat-capacity conventional products in the market stock, reduce the loss of relevant diagnosis and treatment resources for high-heat-capacity products, increase economic benefits, and achieve the multiple utilization of medical resources.

[0070] Regarding the aforementioned water-cooled heat exchange tube 30, in an alternative embodiment, the water-cooled heat exchange tube 30 may be a coiled water-cooled heat exchange tube 30 connected in a layer-by-layer manner in a coil. Specifically, one end of the coiled water-cooled heat exchange tube 30 may be the second inlet 31, and the other end may be the second outlet 32. The coiled water-cooled heat exchange tube 30 can increase the heat exchange circulation path, increase the heat exchange area, and improve the heat exchange efficiency.

[0071] Another alternative embodiment is that, as Figure 3 and Figure 4 shown, the water-cooled heat exchange tube 30 may be formed by juxtaposing and coiling two of the aforementioned coiled water-cooled heat exchange tubes 30 connected in a layer-by-layer manner in a coil. The two coiled water-cooled heat exchange tubes 30 may be the first coiled water-cooled heat exchange tube 331 and the second coiled water-cooled heat exchange tube 332 respectively. Specifically, the first head end of the first coiled water-cooled heat exchange tube 331 may be the second inlet 31, the second tail end of the second coiled water-cooled heat exchange tube 332 may be the second outlet 32, the second inlet 31 and the second outlet 32 are adjacent and arranged side by side on the same side, and the first tail end of the first coiled water-cooled heat exchange tube 331 and the second head end of the second coiled water-cooled heat exchange tube 332 are adjacent and arranged side by side on the other side and are connected by a bent pipe 34 to form a loop.

[0072] On the one hand, the integral water-cooled heat exchange tube 30 formed by connecting two coiled water-cooled heat exchange tubes 30 can further increase the heat exchange circulation path, increase the heat exchange area, and improve the heat exchange efficiency; on the other hand, the inlet (i.e., the second inlet 31) and the outlet (i.e., the second outlet 32) of the water-cooled heat exchange tube 30 are arranged on the same side, which is convenient for pipeline connection, such as convenient oil pipeline connection.

[0073] Based on the foregoing embodiments, as Figure 3 shown, the aforementioned coiled water-cooled heat exchange tube can be wound along the inner wall of the tube shell 10 around the central axis of the tube shell 10. The X-ray tube 203 in the tube shell 10 extends along the central axis direction, and the coiled water-cooled heat exchange tube is wound around the outer circumference of the X-ray tube 203 and is spaced from the X-ray tube 203. Such a setting not only realizes the setting of the coiled water-cooled heat exchange tube close to the X-ray tube 203 where the heat distribution is the most concentrated, but also realizes the heat exchange cooling and heat dissipation treatment within the largest possible range in the tube shell 10, improving the heat dissipation efficiency.

[0074] A specific embodiment is, as Figures 1 to 3 shown, both sides of the tube shell 10 are respectively provided with 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. The tube shell inlet 11 and the tube shell outlet 12 can be arranged on the same side or opposite sides, specifically, they can both be arranged on the side wall of the first anode mounting shell 131 or the second cathode mounting shell 132, or can be respectively arranged on the side walls of the first anode mounting shell 131 and the second cathode mounting shell 132.

[0075] Furthermore, the water-cooled radiator structure 40 and the fluid circulation device can be respectively arranged at the top and side between the first anode mounting shell 131 and the second cathode mounting shell 132, that is, the middle part of the tube shell 10.

[0076] Since the positions of the anode high-voltage plug 201 and the cathode high-voltage plug 202 in the X-ray tube assembly device are generally relatively far from the X-ray tube 203 arranged at the center, generally located at the relatively edge positions, 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 minimize the radiation leakage as much as possible and ensure the overall sealing performance.

[0077] Regarding the aforementioned water-cooled radiator structure 40, a specific embodiment is that the water-cooled radiator structure 40 can include heat dissipation fins and flat copper tubes. The refrigerant flows in the water-cooled radiator structure 40, and the heat is transferred to the heat dissipation fins through the flat copper tubes and dissipated through the heat dissipation fins. Specifically, it can have a plurality of the heat dissipation fins arranged at uniform intervals, and preferably the heat dissipation fins are arranged vertically.

[0078] A preferred embodiment is as follows Figure 1 and Figure 3 As shown, the X-ray tube assembly device provided in the embodiment of the present application may also include a cooling fan assembly, which may include a cooling fan 51 and a fan bracket 52 for installing and fixing the cooling fan 51. Specifically, the cooling fan 51 can be connected and fixed to the fan bracket 52 by bolts, and the fan bracket 52 can be erected, connected and fixed on the aforementioned water-cooled radiator structure 40. Specifically, the fan bracket 52 can be connected and fixed to the heat sink assembly by bolts, and the bottom of the cooling fan 51 can be specifically attached to the upper surface of the cooling fins of the water-cooled radiator structure 40, and the air outlet direction of the cooling fan 51 is upward, so that the air around the water-cooled radiator structure 40 can flow quickly, further force air cooling, accelerate heat dissipation, and further improve heat dissipation efficiency.

[0079] A further embodiment is that the aforementioned heat dissipation fan assembly may include at least two heat dissipation fans 51 arranged side by side to further improve the heat dissipation efficiency.

[0080] Another further embodiment is that a temperature sensor may be built in the tube shell 10, and the temperature sensor is electrically connected to the aforementioned circulation pump 20 and the cooling fan 51. 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 51 are turned off, or the working power of the circulation pump 20 and the cooling fan 51 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 51 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.

[0081] Flexible AI intelligent dynamic temperature control is realized. The temperature distribution of the tube is monitored in real time through the temperature sensor. The AI ​​algorithm can be combined to predict the change of heat load, and the working mode of the heat dissipation module (circulation pump 20 and cooling fan 51) can be dynamically adjusted, such as liquid cooling flow rate and fan speed, to achieve precise temperature control and energy consumption optimization. Specifically, the working power of the circulation pump 20 and the cooling fan 51 can be automatically adjusted according to the temperature change in the tube shell 10 to ensure the efficient operation of the heat dissipation circulation system of the X-ray tube assembly device. At the same time, it can also save energy and reduce consumption, optimize resource utilization, extend the service life of the equipment, prevent the risk of overheating, and improve safety. It can also reasonably design the use of the patient diagnosis equipment to occupy the work during the interval between consultations, so that the diagnosis time is not working.

[0082] An optional embodiment is as follows Figure 1 and Figure 2As shown, the first inlet 21 and the first outlet 22 of the fluid circulation device (such as the circulation pump 20) can be respectively connected to the shell outlet 12 and the third inlet 41 of the water-cooled radiator structure 40 through the first oil pipe 61 and the second oil pipe 62, and the third outlet 42 of the water-cooled radiator structure 40 can be connected to the shell inlet 11 through the third oil pipe 63. Through the connection of the oil pipes, the reliability is strong, and at the same time, it can also play a certain role in cooling the refrigerant in the external circulation.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
