Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] Referring to Figures 1-4, this embodiment of the present invention provides an X-ray tube cooling device, including a heat dissipation box 200, an X-ray tube 300, and a heat exchange assembly 330;

[0028] The heat exchange assembly 330 is disposed on the X-ray tube 300. The first heat exchange channel 331 of the heat exchange assembly 330 is connected to the heat dissipation box 200 through a first circulation pipe. The heat dissipation box 200 is used to circulate and dissipate heat from the first coolant in the first heat exchange channel 331 and the first circulation pipe. The second heat exchange channel 332 of the heat exchange assembly 330 is connected to a second circulation pipe. The second circulation pipe is used to circulate and transport a second coolant to exchange heat with the X-ray tube 300. The first coolant is used to exchange heat with the second coolant.

[0029] Specifically, the heat exchange assembly 330 is provided with a first heat exchange channel 331 and a second heat exchange channel 332. The first heat exchange channel 331 and the second heat exchange channel 332 are not interconnected. The first coolant in the first heat exchange channel 331 exchanges heat with the second coolant in the second heat exchange channel 332, thereby cooling the second coolant in the second heat exchange channel 332 where the temperature is higher. After being cooled, the second coolant is then introduced into the X-ray tube 300 through the second circulation pipe, thereby absorbing the heat inside the X-ray tube 300. That is, the X-ray tube 300 is cooled by heat exchange through the second coolant, preventing heat from accumulating inside the X-ray tube 300. Furthermore, the second coolant circulates and exchanges heat with the X-ray tube 300, resulting in good heat dissipation.

[0030] The first coolant, after heat exchange with the second coolant in the first heat exchange channel 331, is transported to the heat sink 200 through the first circulation pipe, where it is cooled. The cooled first coolant is then transported back to the first heat exchange channel through the first circulation pipe to exchange heat with the second coolant. This circulation of the first coolant through the heat sink 200 ensures effective heat exchange between the first and second coolants, thereby guaranteeing efficient cooling of the X-ray tube 300 by the second coolant.

[0031] Referring to Figure 2, optionally, the first heat exchange channel 331 is a W-shaped channel, and the second heat exchange channel 332 is an M-shaped channel.

[0032] Specifically, the first heat exchange channel 331 is configured as a W-shaped channel, thereby increasing the heat exchange area of ​​the first heat exchange channel 331 within a limited space; similarly, the second heat exchange channel 332 is configured as an M-shaped channel, also increasing the heat exchange area of ​​the second heat exchange channel 332 within a limited space. Therefore, the heat exchange area between the W-shaped first heat exchange channel 331 and the M-shaped second heat exchange channel 332 is large, resulting in high heat exchange efficiency and high cooling efficiency of the second coolant, thereby improving the heat dissipation efficiency of the X-ray tube 300.

[0033] Optionally, the first heat exchange channel 331 and the second heat exchange channel 332 are arranged alternately.

[0034] Specifically, the first heat exchange channel 331 and the second heat exchange channel 332 are arranged in an alternating manner, which increases the contact area between the first heat exchange channel 331 and the second heat exchange channel 332 and reduces the heat exchange distance, thereby improving the heat exchange efficiency between the first heat exchange channel 331 and the second heat exchange channel 332.

[0035] Referring to Figure 1, optionally, the first circulation pipe includes a first input pipe 310 and a first output pipe 320. The first end of the first input pipe 310 is connected to the heat sink 200, the second end of the first input pipe 310 is connected to the input end of the first heat exchange channel 331, the output end of the first heat exchange channel 331 is connected to the second end of the first output pipe 320, and the first end of the first output pipe 320 is connected to the heat sink 200.

[0036] Specifically, the first end of the first input pipe 310 is connected to the heat sink 200, and the second end of the first input pipe 310 is connected to the input end of the first heat exchange channel 331. The first input pipe 310 is used to transport the first coolant, after cooling in the heat sink 200, to the first heat exchange channel 331. The output end of the first heat exchange channel 331 is connected to the second end of the first output pipe 320, and the first end of the first output pipe 320 is connected to the heat sink 200. The first coolant, after heat exchange with the second coolant in the first heat exchange channel 331, is transported to the heat sink 200 for heat dissipation through the first output pipe 320. The first coolant circulates between the heat sink 200 and the first heat exchange channel 331 through the first input pipe 310 and the first output pipe 320, ensuring the cooling effect of the first coolant on the second coolant.

[0037] Optionally, the second circulation pipe includes a second input pipe 360, a second output pipe 350, and a third heat exchange channel. The third heat exchange channel is disposed inside the X-ray tube 300. The first end of the second input pipe 360 ​​is connected to the output end of the third heat exchange channel, the second end of the second input pipe 360 ​​is connected to the input end of the second heat exchange channel 332, the output end of the second heat exchange channel 332 is connected to the second end of the second output pipe 350, and the first end of the second output pipe 350 is connected to the input end of the third heat exchange channel.

[0038] Specifically, the second circulation pipeline consists of a second input pipeline 360, a second output pipeline 350, and a third heat exchange channel. The third heat exchange channel is located inside the X-ray tube 300, where the second coolant flowing within it exchanges heat generated within the X-ray tube 300, thereby cooling the X-ray tube 300. The first end of the second input pipeline 360 ​​is connected to the output end of the third heat exchange channel, and the second end of the second input pipeline 360 ​​is connected to the input end of the second heat exchange channel 332. The second coolant, cooled by the first coolant in the second heat exchange channel 332, is transported to the third heat exchange channel through the second input pipeline 360. The output end of the second heat exchange channel 332 is connected to the second end of the second output pipeline 350, and the first end of the second output pipeline 350 is connected to the input end of the third heat exchange channel. The second coolant, after heat exchange with the X-ray tube 300 in the third heat exchange channel, is transported to the second heat exchange channel 332 through the second output pipeline 350. The second coolant is circulated between the X-ray tube 300 and the second heat exchange channel 332 through the second input pipe 360, the second output pipe 350 and the third heat exchange channel to ensure the cooling effect of the second coolant on the X-ray tube 300.

[0039] Optionally, the input end of the first heat exchange channel 331 and the output end of the second heat exchange channel 332 are located on the same side, and the output end of the first heat exchange channel 331 and the input end of the second heat exchange channel 332 are located on the same side.

[0040] Specifically, the input end of the first heat exchange channel 331 is used to input the first coolant after it has been cooled by the heat sink 200, and the output end of the second heat exchange channel 332 is used to output the second coolant to the second input pipe 360, thereby delivering it to the X-ray tube 300. By setting the input end of the first heat exchange channel 331 and the output end of the second heat exchange channel 332 on the same side, and setting the output end of the first heat exchange channel 331 and the input end of the second heat exchange channel 332 on the same side, the first coolant and the second coolant flow relative to each other, thereby ensuring that the first coolant can continuously flow into the first heat exchange channel 331 to continuously exchange heat with the second coolant, resulting in good heat dissipation effect.

[0041] Optionally, the heat sink 200 is provided with a first drive pump 210, which is used to drive the first coolant to circulate between the first circulation pipe, the heat sink 200 and the first heat exchange channel 331; the X-ray tube 300 is provided with a second drive pump 340, which is used to drive the second coolant to circulate between the second heat exchange channel 332 and the second circulation pipe.

[0042] Specifically, the first drive pump 210 installed on the heat sink 200 drives the first coolant to circulate between the first circulation pipe, the heat sink 200, and the first heat exchange channel 331. The power of the first drive pump 210 can be increased or decreased according to heat dissipation requirements, thereby changing the circulation speed of the first coolant and thus altering the heat exchange efficiency between the first and second coolants. The power of the first drive pump 210 can be flexibly controlled according to the heat dissipation requirements of the X-ray tube 300. Similarly, the second drive pump 340 drives the second coolant to circulate between the second heat exchange channel 332 and the second circulation pipe. The power of the second drive pump 340 can be increased or decreased according to heat dissipation requirements, thereby changing the circulation speed of the second coolant and thus altering the heat exchange efficiency between the second coolant and the X-ray tube 300.

[0043] In some embodiments, the heat sink 200 is further connected to a third circulation pipe, which is used to deliver a third coolant to circulate and cool the control box 100.

[0044] Specifically, the control box 100 and the heat sink 200 are connected by a third circulation pipe. The third circulation pipe is used to transport a third coolant to circulate and cool the control box 100, thereby ensuring the working stability and thermal stability of the control box 100.

[0045] Optionally, the heat dissipation box 200 is provided with a plurality of heat dissipation plates 240, and a first heat dissipation coil 220 and a second heat dissipation coil 230 are wound between the plurality of heat dissipation plates 240. The input end of the first heat dissipation coil 220 is connected to the first end of the first output pipe 320, and the output end of the first heat dissipation coil 220 is connected to the first end of the first input pipe 310. The third circulation pipe includes a third output pipe 120 and a third input pipe 110. The first end of the third input pipe 110 is connected to the control box 100, and the second end of the third input pipe 110 is connected to the output end of the second heat dissipation coil 230. The first end of the third output pipe 120 is connected to the control box 100, and the second end of the third output pipe 120 is connected to the input end of the second heat dissipation coil 230.

[0046] Specifically, referring to Figures 3 and 4, the heat dissipation box 200 is equipped with multiple heat dissipation plates 240. First heat dissipation coils 220 and second heat dissipation coils 230 are wound around the heat dissipation plates 240, thereby dissipating heat from the first coolant in the first heat dissipation coils 220 and the third coolant in the second heat dissipation coils 230. By winding the first heat dissipation coils 220 and 230 between the multiple heat dissipation plates 240, the heat dissipation area is increased, improving heat dissipation efficiency. Furthermore, the alternating winding of the first heat dissipation coils 220 and 230 around the multiple heat dissipation plates 240 improves the space utilization of the first heat dissipation coils 220 and 230, thus reducing the area of ​​the heat dissipation box 200 while maintaining the same heat dissipation effect. Multiple cooling fans or circulating refrigerant can also be installed inside the heat dissipation box 200, with the circulating refrigerant connected to devices such as air conditioners.

The first coolant in the first heat exchange channel 331 exchanges heat with the second coolant in the second heat exchange channel 332, thereby cooling the second coolant. The second coolant is then transported to the X-ray tube 300 through the second circulation pipe for heat exchange, thus cooling the X-ray tube 300. Simultaneously, the first coolant is introduced into the first circulation pipe through the heat dissipation box 200 for heat dissipation. This cycle of cooling the X-ray tube 300 with the second coolant, cooling the second coolant with the first coolant, and cooling the first coolant with the heat dissipation box 200 ensures continuous and efficient heat dissipation of the X-ray tube 300. This improves the heat dissipation and cooling effect of the X-ray tube 300, ensures stable working performance of the X-ray tube 300, and prevents heat accumulation from damaging the structure of the X-ray tube 300.
