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 devices, X-ray tube assemblies have been widely used and are widely applied in X-ray machines, X-ray imaging systems, CT scanners, etc. A general X-ray tube assembly usually 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 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 existing design scheme of the above-mentioned general 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, and the fluidity of the internal insulating oil is poor. This may lead to uneven distribution of internal heat, resulting in a large temperature difference near and around the focal point. For example, it may 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 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 - 60 minutes to resume work after shutdown, affecting the normal operation and work 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, when the heat capacity of the existing tube design reaches the use bottleneck, it cannot meet the high-frequency and long-duration diagnostic application requirements of the medical system. Summary of the Invention

[0014] A temperature sensor is arranged inside the tube housing, and the temperature sensor is linked and electrically connected to the circulation pump and the heat dissipation fan. When the temperature inside the tube housing is lower than the preset normal working temperature range, the working power of the circulation pump and the heat dissipation fan is turned off or reduced. When the temperature inside the tube housing is higher than the preset normal working temperature range, the working power of the circulation pump and the heat dissipation fan is increased.

[0015] Further, the heat sink assembly is an arc-shaped heat sink assembly, and the radian of the arc-shaped heat sink assembly is the same as the radian of the middle part of the tube housing. The arc-shaped heat sink assembly is fixedly attached to the middle part of the tube housing.

[0016] Furthermore, the arc-shaped heat sink assembly includes an arc-shaped heat dissipation plate and a plurality of first heat dissipation fins fixedly arranged on the upper surface of the arc-shaped heat dissipation plate along the arc surface of the arc-shaped heat dissipation plate.

[0017] Furthermore, a plurality of convex grooves are also opened upward on the upper surface of the arc-shaped heat dissipation plate;

The first heat dissipation end section extends upward from the opening and is inserted into the arc-shaped heat sink assembly and directly extends into the convex groove. A plurality of the convex grooves are arranged in one-to-one correspondence with a plurality of the L-shaped heat pipes.

[0019] Furthermore, the heat sink assembly includes a straight plate-shaped heat dissipation plate and a plurality of second heat dissipation fins uniformly and fixedly arranged on the upper surface of the straight plate-shaped heat dissipation plate.

[0020] Even further, the heat sink assembly further includes a straight plate-shaped heat extraction plate arranged at the bottom of the straight plate-shaped heat dissipation plate. A plurality of strip-shaped slots penetrating up and down are formed in the straight plate-shaped heat extraction plate. A plurality of the strip-shaped slots are arranged in one-to-one correspondence with a plurality of the heat pipes.

[0021] Even further, the heat pipe is arranged as a U-shaped heat pipe.

[0023] With such a setting, not only can the insulating oil inside the tube shell circulate, improving the oil fluidity and making the heat distribution more uniform, but also heat can be extracted through the heat extraction ends of the heat pipes inserted into the anti-radiation heat extraction plates attached to the inner wall of the tube shell, and the heat inside the tube shell can be dissipated in time through the heat dissipation ends of the heat pipes inserted into the heat sink assembly. This solves the problem that the heat inside the tube shell cannot be dissipated in time, 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, or even component damage, thereby reducing the service life of the tube and affecting the normal operation process and operation efficiency; and the good heat dissipation effect can also reduce the imaging instability problem of the X-ray tube caused by overheating, improving the clarity and quality of the imaging.

[0072] 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.

[0073] As Figures 1 to 8 shown, an X-ray tube assembly device is provided in an embodiment of the present application. The X-ray tube assembly device includes a tube shell 10, and an anode high-voltage plug 201, a cathode high-voltage plug 202, and an X-ray tube 203 disposed in the tube shell 10. The tube shell 10 is hermetically arranged, and insulating oil is filled in the tube shell 10 for insulation.

[0074] Specifically, the X-ray tube assembly device further includes a fluid circulation device disposed outside the tube shell 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 shell outlet 12) and the inlet (i.e., the tube shell inlet 11) of the tube shell 10 through a first oil pipe 31 and a second oil pipe 32. The tube shell inlet 11 and the tube shell outlet 12 are communicated with the insulating oil filled in the tube shell 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 shell 10 by bolts. In this way, when the fluid circulation device starts to work, the insulating oil in the tube shell 10 can circulate through the fluid circulation device, improving the oil fluidity inside the tube shell 10, making the insulating oil evenly distributed, and making the heat distribution inside the tube shell 10 uniform.

[0075] More specifically, a heat-radiation-proof heat extraction plate 14 is attached inside the shell 10. A plurality of openings 15 are formed in the middle of the shell 10, and each of the openings 15 leads to the heat-radiation-proof heat extraction plate 14. The X-ray tube assembly device further includes a heat dissipation assembly disposed outside the shell 10, which includes a heat sink assembly attached to the outer surface of the middle part of the shell 10 and a plurality of heat pipes. The heat extraction ends of the heat pipes are hermetically inserted into the openings 15 on the shell 10 and connected to the heat-radiation-proof heat extraction plate 14 inside the shell 10 for heat extraction, and the heat dissipation ends of the heat pipes are inserted into the heat sink assembly for heat dissipation. The gaps of the openings can be sealed by welding processes or the like.

[0076] Since the heat-conducting medium of the existing X-ray tube assembly device is insulating oil, and the heat-conducting performance of the oil is not good and the heat dissipation effect is poor, in the embodiment of the present application, heat can be extracted through each heat pipe and the heat-radiation-proof heat extraction plate 14, so as to conduct and dissipate heat quickly and efficiently. The heat pipe realizes efficient heat transfer through a phase change cycle, and not only has high heat-conducting performance and 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.

[0077] 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 shell 10, the inlet and outlet of the fluid circulation device are respectively communicated with the outlet and inlet of the shell 10. When the fluid circulation device starts to work, the insulating oil inside the shell 10 can circulate through the fluid circulation device, improving the fluidity of the oil inside the shell 10, making the insulating oil evenly distributed and the heat inside the shell 10 evenly distributed; and a heat-radiation-proof heat extraction plate 14 is attached to the inner wall of the shell 10 for heat extraction inside the shell 10, and a plurality of openings 15 are formed in the middle of the shell 10, and each of the openings 15 leads to the heat-radiation-proof heat extraction plate 14; a heat dissipation assembly is also disposed outside the shell 10, which includes a heat sink assembly attached to the outer surface of the middle part of the shell 10 and a plurality of heat pipes. The heat extraction ends of the heat pipes are hermetically inserted into the openings 15 on the shell 10 and connected to the heat-radiation-proof heat extraction plate 14 inside the shell 10 for heat extraction, and the heat dissipation ends of the heat pipes are inserted into the heat sink assembly for heat dissipation. The heat conduction efficiency is improved, so that the heat generated inside the shell 10 can be transferred to the heat dissipation end at a faster speed, effectively reducing the temperature peak value of the core components inside the tube.

[0078] With such a setting, not only can the insulating oil inside the tube shell 10 circulate and flow, improving the oil fluidity and making the heat distribution more uniform, but also the heat extraction ends of the heat pipes can be inserted into the anti-radiation heat extraction plate 14 attached to the inner wall of the tube shell 10 to extract heat, and the heat dissipation ends of the heat pipes can be inserted into the heat sink assembly to dissipate the heat inside the tube shell 10 in a timely manner, solving the problem that the heat inside the tube shell 10 cannot be dissipated in a timely manner. 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; 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 that due to local overheating, temperature alarms are caused, 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.

[0079] A specific embodiment is, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, both sides of the tube shell 10 are provided with a first anode installation housing 131 and a second cathode installation housing 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 installation housing 131 and the second cathode installation housing 132. Preferably, the shapes of the first anode installation housing 131 and the second cathode installation housing 132 can be similar to a cylindrical shape extending horizontally. And the heat sink assembly and the fluid circulation device can be arranged at the top and side between the first anode installation housing 131 and the second cathode installation housing 132, that is, at the top and side of the middle part of the tube shell 10.

[0080] Since the positions of the anode high-voltage plug 201 and the cathode high-voltage plug 202 of the X-ray tube assembly device are generally relatively far from the X-ray tube 203 arranged at the center, generally located at relatively marginal positions, the radiation will be less. The tube shell inlet 11 and the tube shell outlet 12 are arranged on the first anode installation housing 131 and the second cathode installation housing 132, which can minimize the radiation leakage and ensure the overall sealing performance.

[0081] A preferred embodiment is, as Figures 1 to 8As shown, the heat dissipation assembly of the X-ray tube assembly device provided in the embodiment of the present application may further include a heat dissipation fan 71 and a fan bracket 72 for mounting 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 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.

[0082] Furthermore, a temperature sensor may be built into the housing 10 and electrically connected to the aforementioned circulation pump 20 and cooling fan 71. When the temperature inside the housing 10 is too low, below a preset normal operating temperature range, the circulation pump 20 and cooling fan 71 are shut down, or their operating power is reduced, thereby slowing the flow of oil and reducing energy consumption. The fan is stopped, thereby reducing unnecessary energy consumption. When the temperature inside the housing 10 is too high, above a preset normal operating temperature range, the operating power of the circulation pump 20 and cooling fan 71 is increased, accelerating the flow of oil and improving heat dissipation efficiency. The fan speed is increased, thereby enhancing air flow and improving heat dissipation.

[0083] Flexible AI intelligent dynamic temperature control is achieved. The temperature distribution of the tube is monitored in real time through a temperature sensor. The AI algorithm can be combined to predict changes in heat load and dynamically adjust the working mode of the heat dissipation module (circulation pump 20 and cooling fan 71), such as liquid cooling flow 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 71 can be automatically adjusted according to the temperature changes 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 overheating risks, and improve safety. It can also reasonably design the use of the patient diagnosis equipment during the interval between consultations to achieve non-operation during the diagnosis time.

[0084] A preferred embodiment is that the X-ray tube assembly device provided in the embodiment of the present application is an integrated molding structure, specifically, the external fluid circulation device and the heat dissipation assembly are integrated with the tube shell, specifically, the heat dissipation assembly, heat pipe, circulation pump 20 and other components can be highly integrated, and the redundant structure is reduced by optimizing the design to reduce the module weight.

[0085] With such a setting, on the one hand, it can make the structure of the X-ray tube component device more compact, tightly integrate all components together, reduce the volume occupied by the overall device, save space, simplify the installation process, reduce the installation time and the complexity of installation operations, and improve the convenience of maintenance; on the other hand, it can also enhance the sealing performance and achieve a more efficient heat conduction path. The integrated structure components are easier to achieve a good sealing effect, reduce the leakage risk, and the integrated structure can also ensure that heat is transferred to the heat sink structure more directly and efficiently, improving the heat dissipation efficiency.

[0086] Moreover, the X-ray tube component 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.

[0087] Hereinafter, the present application specifically provides two specific embodiments for detailed description.

[0088] The first embodiment

[0089] As Figures 1 to 4 shown, the heat sink component of this first embodiment is set as an arc-shaped heat sink component 40. The arc-shaped heat sink component 40 may specifically include an arc-shaped heat sink plate 41 and a plurality of first heat dissipation fins 42 fixedly arranged on the upper surface of the arc-shaped heat sink plate 41 along the arc surface of the arc-shaped heat sink plate 41. The plurality of first heat dissipation fins 42 are preferably arranged vertically. And the radian of the arc-shaped heat sink component 40 is consistent with the radian in the middle of the tube shell 10, so that the arc-shaped heat sink plate 41 is more closely attached and fixedly connected to the tube shell 10. The arc-shaped heat sink component has a higher degree of fit with the tube shell 10 and a larger covered area, and the heat dissipation effect is better.

[0090] Furthermore, as Figure 3 and Figure 4 shown, a plurality of convex grooves 43 are also opened upward on the upper surface of the arc-shaped heat sink plate 41. Correspondingly, the heat pipe of this first embodiment is set as an L-shaped heat pipe 61. The L-shaped heat pipe 61 may include a first heat extraction end section 611 and a first heat dissipation end section 612 extending at a right angle respectively. The first heat extraction end section 611 is hermetically inserted into the tube shell 10 through the opening 15 of the tube shell 10 and is welded and fixedly attached to the anti-radiation heat extraction plate 14 inside the tube shell 10. The first heat dissipation end section 612 extends upward from the opening 15 and is inserted into the arc-shaped heat sink component 40 and extends straight into the convex grooves 43 thereof, and the plurality of convex grooves 43 are arranged in one-to-one correspondence with the plurality of L-shaped heat pipes 61. With such a setting, on the one hand, it can improve the area of the heat extraction end and the heat dissipation end of the heat pipe as much as possible, improving the heat dissipation speed and efficiency; on the other hand, it can improve the installation and fixing reliability of the heat pipe.

[0091] The second embodiment

[0092] As Figures 5 to 8 shown, the heat sink assembly of the second embodiment may include a straight plate-shaped heat dissipation plate 51 and a plurality of second heat dissipation fins 52 uniformly and fixedly arranged on the upper surface of the straight plate-shaped heat dissipation plate 51, and a straight plate-shaped heat extraction plate 53 arranged at the bottom of the straight plate-shaped heat dissipation plate 51. A plurality of strip-shaped slots 531 penetrating up and down are formed in the straight plate-shaped heat extraction plate 53.

[0093] Correspondingly, the heat pipe of the second embodiment is arranged as a U-shaped heat pipe 62. The U-shaped heat pipe 62 may include a second heat extraction end segment 621 and a second heat dissipation end segment 622 extending in parallel, and a third connection segment 623 connecting the second heat extraction end segment 621 and the second heat dissipation end segment 622. The second heat extraction end segment 621 is hermetically inserted into the tube shell 10 through the opening 15 of the tube shell 10 and is welded and fixedly attached to the anti-radiation heat extraction plate 14 inside the tube shell 10. The third connection segment 623 passes out through the opening 15 and the second heat dissipation end segment 622 is inserted and embedded in the strip-shaped slot 531. The plurality of strip-shaped slots 531 are arranged in one-to-one correspondence with the plurality of U-shaped heat pipes 62. With such an arrangement, on the one hand, the area of the heat extraction end and the heat dissipation end of the heat pipe can be increased as much as possible to improve the heat dissipation speed and efficiency; on the other hand, the installation and fixation reliability of the heat pipe can be improved.

[0094] 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.
