[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figure 1-7 shown, the embodiments of the present utility model provide an X-ray source device with integrated power supply and cooling, including: a device housing 100, an electronic control box 200, an X-ray emitter 300, a power supply circuit 500, a cooling component, and a circulation component.

[0032] The inside of the device housing 100 is filled with an insulating refrigerant. In this embodiment, cooling oil is selected, and the device housing 100 is sealed all around.

[0033] Both the X-ray emitter 300 and the power supply circuit 500 are installed in the device housing 100, so as to share the insulating refrigerant for cooling. Specifically, the power supply circuit 500 is installed in the device housing 100 on one side of the X-ray emitter 300. That is to say, the X-ray emitter 300 and the power supply circuit 500 are arranged at intervals in the device housing 100 to make full use of the internal space of the entire device housing 100 and also provide sufficient heat dissipation space for the X-ray emitter 300 and the power supply circuit 500.

[0034] The electric control box 200 is installed outside the device housing 100. The electric control box 200 is electrically connected to the X-ray emitter 300 through the power supply circuit 500 to realize the control of the X-ray emitter 300. The power input line of the power supply circuit 500 passes through the device housing 100 and the electric control box 200 in sequence and is connected to an external power supply.

[0035] Specifically, a control board 210 is provided in the electric control box 200. The control board 210 is electrically connected to the power supply circuit 500 to realize the drive control of the power supply circuit 500. The X-ray emitter 300 is powered on through the power supply circuit 500 to realize X-ray detection. The signal line of the control board 210 passes through the electric control box 200 and is connected to an external controller.

[0036] The X-ray emitter 300 includes: an X-ray shielding barrel 310, a first end cap 320 installed on the cathode side of the X-ray shielding barrel 310, a second end cap 330 installed on the anode side of the X-ray shielding barrel 310, and an X-ray tube located inside the X-ray shielding barrel 310. A first through hole 323 and a third through hole 324 are axially formed through the first end cap 320. The first through hole 323 is used for the power line to pass through, and the third through hole 324 is used for the circulation of the insulating refrigerant. A first protective cover 321 is installed outside the first end cap 320 to cover the first through hole 323 to prevent the rays in the X-ray emitter 300 from leaking out through the first through hole 323. A first channel perpendicular to the first through hole 323 is formed in the first protective cover 321. The first channel is used for the power line and the refrigerant pipeline to pass through.

[0037] A second through hole 334 is axially formed through the second end cap 330. A second protective cover is installed outside the second end cap 330 to cover the second through hole 334 to prevent the rays in the X-ray emitter 300 from leaking out through the second through hole 334. A second channel perpendicular to the second through hole 334 is formed in the second protective cover.

[0038] Specifically, the power supply circuit 500 is connected to the high-voltage power input / output terminal of the X-ray emitter 300 through the high-voltage power supply wiring 381, passing through the first channel and the first through-hole 323 in sequence. The power supply circuit 500 is connected to the tube power input / output terminal of the X-ray emitter 300 through the tube power supply wiring 382, passing through the second channel and the second through-hole 334 in sequence, so as to supply power to the X-ray emitter 300.

[0039] The cooling assembly is arranged in the electric control box 200 and includes a radiator 220 and a fan 230 for dissipating heat from the radiator 220. The radiator 220 includes heat dissipation pipes and heat dissipation fins connected to the heat dissipation pipes.

[0040] The circulation assembly includes a first pipeline 410, a second pipeline 430 and a circulation pump 440. The first pipeline 410 penetrates through the equipment housing 100 and connects the output end of the cooling assembly and the end cover of the cathode end of the X-ray emitter 300. The end cover of the anode end of the X-ray emitter 300 is hollowed out. The circulation pump 440 penetrates through and is provided on the outer side wall of the equipment housing 100 on the side where the power supply circuit 500 is located. The input end 450 of the circulation pump 440 communicates with the inside of the equipment housing 100. The output end of the circulation pump 440 is connected to the input end of the cooling assembly through the second pipeline 430. Specifically, the first end of the first pipeline 410 is connected to the output end of the heat dissipation pipe. The second end of the first pipeline 410 passes through the first channel and communicates with the third through-hole 324, and the insulating refrigerant is input into the X-ray emitter 300 through the third through-hole 324, especially the cathode end with relatively large heat generation, and the insulating refrigerant is taken out of the X-ray emitter 300.

[0041] A hollow structure 331 is penetrated and provided on the peripheral wall of the second end cover 330, which is convenient for outputting the insulating refrigerant inside the X-ray emitter 300. The input end 450 of the circulation pump 440 and the hollow structure 331 are diagonally arranged in the equipment housing 100, and the power supply circuit 500 is located between the input end 450 of the circulation pump 440 and the hollow structure 331. Thus, the insulating refrigerant output from the inside of the X-ray emitter 300 can flow through the area where the input end 450 of the circulation pump 440 and the hollow structure 331 are located, that is, the power supply circuit 500 can be fully cooled. The insulating refrigerant carrying the heat inside the X-ray emitter 300 and the heat of the power supply circuit 500 is output from the circulation pump 440, realizing the heat dissipation inside the equipment housing 100.

[0042] The second pipeline 430 is located in the electric control box 200. The second pipeline 430 is connected between the output end of the circulation pump 440 and the input end of the heat dissipation pipeline, and returns the insulating refrigerant output from the inside of the equipment housing 100 to the heat dissipation pipeline. The fan 230 blows air outwards for cooling. After cooling, the insulating refrigerant is re-fed into the X-ray emitter 300 to realize a cooling circulation loop.

[0043] An air inlet and an air outlet are provided on the electric control box 200. The air outlet is located on the housing of the electric control box 200 at the corresponding position of the radiator 220, which is convenient for outputting the heat in the heat dissipation pipeline to the outside. The setting of the air outlet can also realize the overall air cooling of the components inside the electric control box 200, especially the heat dissipation of the control board 210.

[0044] As described above, the present invention provides an X-ray source device with integrated power supply and cooling. Adopting an integrated design, the cooling system (circulation pump + cold radiator + fan) is integrated into the electrical power supply and control. Through a compact and reasonable design, a high-integration layout is achieved, the cooling effect of the product is improved, the structural cost is low, and the installation is convenient. At the same time, the cooling system can dissipate heat from the X-ray emitter 300 and the power circuit 500 inside the equipment, and can also dissipate heat from the electric control board in the electric control box 200. One set of cooling system realizes the simultaneous heat dissipation of internal and external heat sources, and combines the utilization rate and integration degree of the equipment.
