Description

Technical Field

[0001] This application relates to a voltage stabilizing and boosting device and its setting method for a transmitter device cooling system in the field of cyclotron technology. Background Technology

[0002] Nuclear medicine is a branch of medicine and medical imaging (medical imaging) that utilizes the nuclear properties of matter for diagnosis and treatment. For a long time, radiotherapy has used conventional methods (electron, X-ray, and gamma rays). Although these have shown good efficacy in treating certain tumors, their physical and biological properties cause significant damage to surrounding healthy tissues while killing cancer cells, resulting in noticeable side effects and even complications. With the continuous advancement of medical technology, to address the problem of significant side effects from radiotherapy, it is now possible to explore the use of other radioactive particles such as protons, neutrons, and heavy ions to treat cancer.

[0003] Specifically, the process of nuclear medicine involves accelerating particles to a predetermined speed using a cyclotron and then transmitting them from a transmitter. Since the transmitter has a large power, it generally needs to be cooled by liquid cooling, and therefore a matching liquid cooling system is designed.

[0004] The transmitter has very strict requirements for its water supply branch, primarily because the transmitter's supply water pressure must not exceed 3 Bar, and the return water pressure must exceed 1 Bar. However, current solutions for similar projects only provide a supply water pressure of 5 Bar and a return water pressure of 2 Bar. Excessive supply water pressure negatively impacts the transmitter's internal operation. In practice, it was found that simply adjusting the existing inlet and outlet valves to reduce the supply water pressure causes the return water pressure to drop to 0.5 Bar, resulting in insufficient return water pressure. Therefore, the supply and return water pressures cannot simultaneously meet the requirements. Summary of the Invention

[0005] The purpose of this application is to at least solve one of the technical problems existing in the prior art, and to provide a pressure stabilizing and boosting device and its setting method for a transmitter device cooling system, which can increase the return water pressure while stabilizing the supply water pressure, thereby meeting the water pressure requirements of the transmitter.

[0006] According to a first aspect of this application, a voltage stabilizing and boosting device for a transmitter device cooling system is provided, comprising:

[0035] Reference Figure 1 The voltage stabilizing and boosting device of the transmitter device cooling system in the first aspect embodiment of this application includes a cooling system body 100, a pressure reducing valve 200, a booster pump 300, a first throttle valve 400, and a second throttle valve 500. The cooling system body 100 is used to connect to the transmitter 700 and drive the circulation of cooling water to achieve liquid cooling of the transmitter 700. The cooling system body 100 includes an inlet pipe 110 and an outlet pipe 120. The inlet pipe 110 is used to connect to the inlet end of the transmitter 700, and the outlet pipe 120 is used to connect to the outlet end of the transmitter 700.

[0036] One end of the pressure reducing valve 200 is connected to an external water source device, and the other end is connected to the inlet pipe 110. It is used to reduce the pressure of water flowing from the water source device, thereby meeting the water pressure requirements of the transmitter 700. In this embodiment, to further reduce the water pressure and achieve more precise control, a first throttle valve 400 is also provided between the pressure reducing valve 200 and the external water source device. The first throttle valve 400 is connected to the pressure reducing valve 200, providing a first-stage pressure reduction for the external water source, while the pressure reducing valve 200 provides a second-stage pressure reduction. This arrangement not only improves the accuracy of water pressure control but also allows the first throttle valve 400 to share some of the pressure reduction burden of the pressure reducing valve 200, reducing the losses caused by the high-pressure water source to the pressure reducing valve 200. In this application, the water source device refers to a water tank, water pump, or other device or equipment capable of providing a water source.

[0037] One end of the booster pump 300 is connected to the outlet pipe 120, and the other end is connected to the second throttle valve 500, which is used to connect to external water circulation equipment. The booster pump 300 pressurizes the water flowing out of the transmitter 700 to meet the return water pressure requirements. However, because the booster pump 300 has a large pressurization range, it is difficult to precisely control the water pressure. After the water pressure is increased, it is then finely regulated by the second throttle valve 500. In this application, the water circulation equipment refers to a container or device for temporarily storing outflowing water, which is connected to the water source equipment to realize the recycling of cooling water.

[0038] Furthermore, the pressure stabilizing and boosting device of the transmitter's cooling system also includes a first check valve 600, which is disposed between the booster pump 300 and the second throttle valve 500. The booster pump 300 is connected to the second throttle valve 500 through the first check valve 600. The first check valve 600 is specifically a one-way valve, which is used to limit the water flow to flow only from the booster pump 300 to the second throttle valve 500, preventing backflow of water.

[0039] For the cooling system body 100, the water inlet pipe 110 further includes a third throttle valve 111, which is connected to the water inlet of the transmitter 700. The third throttle valve 111 is used to further adjust the water pressure entering the transmitter 700 and improve the accuracy of water pressure control.

[0040] Furthermore, the water inlet pipe 110 also includes a constriction pipe 112, which is connected to the third throttle valve 111. The two ends of the constriction pipe 112 are a large-diameter end and a small-diameter end, respectively. The inner diameter of the large-diameter end is larger than the inner diameter of the small-diameter end. The water flow in the constriction pipe 112 flows from its large-diameter end to its small-diameter end, thereby accelerating the water flow velocity through the narrowed channel and also increasing the water flow pressure.

[0041] The water outlet pipe 120 includes a second check valve 121, which is connected to the water outlet of the transmitter 700. Specifically, the second check valve 121 is a one-way valve used to limit the water flow to flow only from the water outlet of the transmitter 700 to the booster pump 300 and finally out to the water circulation equipment, preventing the water from flowing back into the transmitter 700.

[0042] Furthermore, the water outlet pipe 120 also includes a fourth throttle valve 122, which is connected to the water outlet end of the transmitter 700. The fourth throttle valve 122 is used to further regulate the water pressure flowing out of the transmitter 700 and improve the accuracy of water pressure control.

[0043] Furthermore, the outlet pipe 120 also includes a swell pipe 123, which is connected to the fourth throttle valve 122. The two ends of the swell pipe 123 are a large-diameter end and a small-diameter end, respectively. The inner diameter of the large-diameter end is larger than the inner diameter of the small-diameter end. The water flow in the swell pipe 123 flows from its small-diameter end to its large-diameter end, thereby slowing down the water flow velocity and reducing the water flow pressure through the widened channel.

[0044] Furthermore, in this application, the number of cooling system bodies 100 is two and they are arranged in parallel, thereby enabling simultaneous liquid cooling of two transmitters 700 and improving the cooling efficiency for multiple transmitters 700. It is easy to understand that the number of cooling system bodies 100 can also be multiple, thereby cooling multiple transmitters 700 separately, which will not be elaborated here.

[0045] The setting method in the second aspect embodiment of this application is based on the voltage stabilization and boosting device of the transmitter device cooling system described above, and the setting steps include:

[0046] S100. The cooling system body 100 is in a stopped state. Adjust the pressure reducing valve 200 and limit its outlet water pressure to 2 to 2.5 Bar.

[0047] S200. Adjust the booster pump 300 and limit its outlet water pressure to 3-3.5 Bar;

[0048] S300. Adjust the first throttle valve 400 and limit its outlet water pressure to 2.5~3 Bar;

[0049] S400. Adjust the second throttle valve 500 and limit its outlet water pressure to 1-2 Bar;

[0050] S500. Activate the cooling system body 100 to cool the transmitter.

[0051] It is easy to understand that after the cooling system body 100 is started, the various valves can also be adjusted to meet the water pressure requirements.

[0052] Reference Figure 2The initial water pressure at the water source equipment is 5 Bar. Although the water pressure drops slightly due to pipeline losses, it is still higher than the 3 Bar required by the transmitter 700. Therefore, by combining the pressure reducing valve 200 and the first throttle valve 400 to reduce the pressure, the water pressure changes according to the first pressure reducing stage 810, and the water pressure drops to 2.8 Bar, which meets the water supply pressure requirements.

[0053] Water pressure is lost within the transmitter 700. Referring to the second pressure reduction stage 820, the water pressure drops to 1.6 Bar and continues to decrease. To address this, the water pressure is increased by the booster pump 300. Referring to the booster stage 830, the water pressure reaches 3.4 Bar, meeting the return water pressure requirements. Further adjustments to the water pressure can then be made via the second throttle valve 500.

[0054] The above is a detailed description of the preferred embodiments of this application. However, this application is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
