Description
Technical Field
[0001] This invention relates to the field of electron accelerator equipment technology, and in particular to an eddy current cooling device and an electron acceleration system. Background Technology
[0002] Existing electron accelerators are usually set up in a relatively sealed chamber. The electron flow generating end can output an electron flow. The electron flow is converged and reflected by a converging plate formed by copper or titanium foil, and then emitted to act on the workpiece to be processed.
[0003] During operation, the converging plate of the electron accelerator has a high temperature and needs to be cooled. In the past, water cooling or outputting inert gas towards the converging plate was used, but the heat dissipation effect is limited and fails to achieve a good heat dissipation effect, which can easily lead to unstable operation of the electron accelerator. If a cooling device is used to cool the inert gas or water before output, a large amount of electrical energy will be required, which will increase the cost. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0033] like Figure 1-3As shown, according to a first aspect embodiment of the present invention, an eddy current cooling device is applied to an electron acceleration system. The electron acceleration system includes a housing 100 and an electron accelerator 200. The housing 100 has an irradiation cavity 110, and the electron accelerator 200 is located in the irradiation cavity 110 (for illustration purposes, the electron accelerator 200 is shown outside the irradiation cavity 110). The eddy current cooling device includes a gas supply module 300, at least one eddy current cooling element 400, and a heat exchange tube 500. The gas supply module 300 is used to output inert gas. The eddy current cooling element 400 is provided with an eddy current air passage 410. The eddy current cooling element 400 is provided with a gas inlet 420, a cold gas outlet 430, and a hot gas outlet 440. The cold gas outlet 430 is connected to the eddy current air passage 410. The first end is connected, the hot gas outlet 440 is connected to the tail end of the vortex air passage 410, the gas inlet 420 is connected to the vortex air passage 410 and the gas inlet 420 is located between the cold gas outlet 430 and the hot gas outlet 440, the gas supply end of the gas supply module 300 is connected to the gas inlet 420, the heat exchange tube 500 is used to contact the converging plate 210 of the electron accelerator 200 for heat exchange, the heat exchange tube 500 includes a heat exchange air passage 510, at least one air inlet 520 and an air outlet 530, the heat exchange air passage 510 is connected to the air inlet 520 and the air outlet 530 respectively, the cold gas outlet 430 is connected to the air inlet 520, and the air outlet 530 is connected to the irradiation cavity 110.
[0034] The converging plate 210 is usually made of titanium foil or copper foil. The converging plate 210 has a certain thickness. Through holes are formed on the converging plate 210 to form a converging window that can converge the electron flow. The heat exchange tube 500 is generally embedded in the converging plate 210 or set on the back of the converging surface of the converging plate 210 for converging the electron flow.
[0035] like Figure 3 As shown, the vortex cooling component 400 is tubular, and the vortex air passage 410 is spirally arranged inside the vortex cooling component 400. The gas inlet 420 is located on the peripheral wall of the spiral vortex air passage 410, and an inert gas, which can be nitrogen, is introduced tangentially. The vortex cooling component 400 can be a one-piece structure or a split structure. If a split structure is used, a sealing ring is provided at the connection position to improve the airtightness of the vortex air passage 410.
[0036] The eddy current cooling device of this invention provides an inert gas supply module 300 that outputs inert gas to the gas inlet 420 of the eddy current cooling component 400. The inert gas is separated into hot and cold air streams through physical properties within the eddy current air passage 410. The cold air stream can directly enter the heat exchange tube 500, which contacts the converging plate 210 of the electron accelerator 200 for heat exchange. The heat from the converging plate 210 is conducted to the inert gas through the heat exchange tube 500, causing the converging plate 210 to cool down rapidly. The inert gas can then be output to the irradiation cavity 110, thus isolating it from the outside air and preventing the electron flow from reacting with oxygen to produce ozone. This design provides excellent cooling, ensuring stable operation of the electron accelerator 200 and continuously supplying inert gas to the irradiation cavity 110, isolating it from the outside air, and ensuring safety and reliability.
[0037] In some embodiments of the present invention, the eddy current cooling component 400 is movably provided with a temperature regulating valve 450 at the hot gas outlet 440, and the temperature regulating valve 450 can movably adjust the hot gas output of the hot gas outlet 440 to change the outlet temperature of the cold gas outlet 430.
[0038] This design utilizes a temperature control valve 450 that moves within the vortex cooling element 400 to adjust the hot air output, thereby changing the outlet temperature of the cold air outlet 430 to the temperature required by the user.
[0039] Specifically, such as Figure 3 As shown, the temperature regulating valve 450 is located in the vortex air passage 410 near the hot gas outlet 440. When the temperature regulating valve 450 is near the hot gas outlet 440, it can block the hot gas outlet 440. As the temperature regulating valve 450 moves away from the hot gas outlet 440, the air passage gap gradually increases, thereby changing the hot gas output of the hot gas outlet 440.
[0040] In some embodiments of the present invention, the vortex cooling device further includes a flow regulating valve 610, wherein the gas supply end of the gas supply module 300 is connected to the gas inlet 420 through the flow regulating valve 610, and the flow regulating valve 610 is used to regulate the gas intake of the gas inlet 420 to change the outlet temperature of the cold air outlet 430.
[0041] The flow regulating valve 610 can regulate the air intake of the gas inlet 420. Users can adjust the flow regulating valve 610 or the temperature regulating valve 450 according to their selection. It should be noted that the air intake of the gas inlet 420 is equal to the sum of the hot gas output and the cold gas output. While adjusting the outlet temperature of the cold gas outlet 430, the cold gas output can also be controlled by adjusting the ratio of the air intake of the gas inlet 420 to the hot gas output, thereby adjusting the heat dissipation efficiency and the supply of inert gas to the irradiation cavity 110.
[0042] In some embodiments of the present invention, the eddy current cooling device further includes a control module (not shown in the figure), which is connected to the flow regulating valve 610 and the temperature regulating valve 450 respectively. The control module implements a flow control method, which includes:
[0043] S710, Obtain the target temperature value of the cold air outlet;
[0044] S720. Calculate at least one of a first gas adjustment command and a second gas adjustment command in the eddy current heat transfer model based on the target temperature value of the cold air outlet. The control module outputs the first gas adjustment command to the flow regulating valve 610 to adjust the air intake of the gas inlet 420, and the control module outputs the second gas adjustment command to the temperature regulating valve 450 to adjust the hot air output of the hot air outlet 440.
[0045] The control module can be selected from processors such as MCU or CPU and their auxiliary circuits.
[0046] Users can set the target temperature value for cold air outlet, or set the target temperature value for cold air outlet according to the heat dissipation requirements of the electron accelerator 200 during operation. Then, based on the eddy current heat transfer model, the required air intake volume of the gas inlet 420 or the required hot air output volume of the hot air outlet 440 is calculated, thereby formulating the first gas adjustment command and the second gas adjustment command that the control module needs to output.
[0047] In some embodiments of the present invention, the eddy current heat transfer model is as follows:
[0048] T c =T i -Q0 / C p *(C0-C h );
[0049] Among them, T c T represents the target temperature value for the cold air outlet. i The inlet temperature is Q0, where Q is the cooling capacity characteristic parameter of the eddy current cooling element, and C is the inlet temperature of the gas inlet. p C is the isobaric specific heat of the inert gas, C0 is the inlet flow rate of the gas, and C h This refers to the air flow rate at the hot air outlet.
[0050] As can be seen from the eddy current heat transfer model, changes in the inlet flow rate of the gas inlet and the outlet flow rate of the hot gas outlet will cause changes in the outlet temperature of the cold gas. Furthermore, the higher the outlet flow rate of the cold gas, the higher the outlet temperature of the cold gas. Therefore, when the outlet gas also provides inert gas to the irradiation cavity, the outlet flow rate of the cold gas can be controlled to ensure that the outlet temperature of the cold gas is not too high. However, simultaneously increasing the inlet flow rate of the gas inlet and the outlet flow rate of the hot gas outlet can ensure that enough inert gas is supplied into the irradiation cavity to isolate the air.
[0051] In some embodiments of the present invention, the vortex cooling device further includes a first flow detection element 620, which is used to detect the air intake of the gas inlet 420, and the control module is connected to the first flow detection element 620.
[0052] The control module can use the gas intake information detected by the first flow detection element 620 to provide feedback control to the flow regulating valve 610, so that the gas intake flow of the gas input port 420 is reasonable and stable.
[0053] In some embodiments of the present invention, such as Figure 1 As shown, the eddy current cooling device further includes a heat sink 630, a heat sink pipe 640, a first transmission pipe 650, a second transmission pipe 660, and a switching valve assembly 670. The first end of the heat sink pipe 640 is connected to the air outlet 530 of the heat exchange pipe 500. The heat sink pipe 640 contacts the heat sink 630 for heat exchange. The tail end of the heat sink pipe 640 is connected to the first end of the first transmission pipe 650 and the first end of the second transmission pipe 660 respectively through the switching valve assembly 670. The tail end of the first transmission pipe 650 is connected to the irradiation chamber 110, and the tail end of the second transmission pipe 660 is connected to the return end of the air supply module 300. The switching valve assembly 670 can control the on / off connection between the tail end of the heat sink pipe 640 and the first end of the first transmission pipe 650, and control the on / off connection between the tail end of the heat sink pipe 640 and the first end of the second transmission pipe 660.
[0054] The heat sink 630 may include multiple heat sink fins, and the heat sink 640 is inserted back and forth in the heat sink fins. The heat sink fins can contact the outside air, thereby dissipating the heat of the inert gas in the heat sink 640.
[0055] The switching valve assembly 670 includes a first switching valve 671 and a second switching valve 672. The tail end of the heat dissipation pipe 640 is connected to the head end of the first transmission pipe 650 through the first switching valve 671, and the tail end of the heat dissipation pipe 640 is connected to the head end of the second transmission pipe 660 through the second switching valve 672. The user can control the on / off state of the first switching valve 671 and the second switching valve 672 respectively.
[0056] Some inert gas can be introduced into the irradiation chamber 110 to work with the inert gas output from the outlet 530 to isolate the air outside the irradiation chamber 110, while some inert gas can be returned to the gas supply module 300 for recycling, reducing the waste of inert gas.
[0057] In some embodiments of the present invention, the gas supply module 300 includes a first container 310, a vaporization component 320, a second container 330, a pressurization component 340, a one-way valve 350, and a third container 360. The first container 310 is used to store liquid inert gas, and the second container 330 and the third container 360 are both used to store gaseous inert gas. The first container 310 is connected to the second container 330 through the vaporization component 320. The gas supply end is disposed on the second container 330. The third container 360 is connected to the second container 330 through the pressurization component 340 and the one-way valve 350. The return end is disposed on the third container 360.
[0058] The first container 310, the second container 330, and the third container 360 can all be in the shape of a tank. The inert gas is compressed and stored in the first container 310, the second container 330, or the third container 360. The vaporization component 320 can include a vaporization pipe and a heating component. The first container 310 is connected to the second container 330 through a main switch valve 370 and a vaporization pipe. The heating component can be a semiconductor heating element. The heating component heats the liquid inert gas in the vaporization pipe, causing the inert gas to vaporize and then be stored in the second container 330. The gas supply end of the second container 330 is connected to the gas inlet 420 through a nitrogen switch valve 380 and a second flow detection component 390. Since there may be multiple eddy current cooling components 400, the nitrogen switch valve 380 can control the gas supply to each eddy current cooling component 400, and the second flow detection component 390 can record the total nitrogen supply.
[0059] In some embodiments of the present invention, there are multiple eddy current cooling elements 400, multiple heat exchange tubes 500, the gas supply end of the gas supply module 300 is connected to each of the gas inlets 420, the cold gas outlets 430 are connected to the air inlets 520 in a corresponding manner, and each of the air outlets 530 is connected to the irradiation chamber 110.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
