Description

Technical Field

[0001] This utility model relates to the field of high-end medical device technology, and in particular to a cooling system and a proton radiotherapy device. Background Technology

[0002] Proton therapy uses a proton beam to irradiate tumors. The proton beam releases energy relatively slowly after entering the body, but releases its maximum energy upon reaching the tumor site, after which the energy rapidly decreases. This characteristic allows the proton beam to precisely target the tumor while minimizing damage to surrounding healthy tissues. Based on these characteristics, proton therapy equipment offers higher precision, better protects healthy tissues around the tumor, and reduces side effects. Therefore, the clinical application of proton therapy equipment is becoming increasingly widespread.

[0003] Protons need to continuously swirl and accelerate within a superconducting cyclotron accelerator, utilizing a magnetic field generated by zero resistance in an ultra-low temperature environment. This ultra-low temperature environment requires liquid helium, but the liquid helium compressor operates at high temperatures. To ensure the proper functioning of the liquid helium compressor, proton therapy equipment is typically equipped with a water-cooling system to continuously cool it. This water-cooling system also needs to continuously cool other subsystems within the proton therapy equipment, such as the radiofrequency system and the accelerator.

[0004] However, in existing technologies, the water cooling system of proton therapy equipment generally includes a water pump, a water tank, and a heat exchanger, which are connected in sequence to form a circulating water circuit. When the water pump operates, it delivers cold water from the water tank to the heat exchanger. The parts of the proton therapy equipment that need to be cooled transfer heat to the heat exchanger, which then removes the heat from those parts.

[0005] If any of the water pump, water tank, or heat exchanger fails, all parts of the proton radiotherapy equipment that need to be cooled will not be adequately cooled, affecting the overall stability of the proton radiotherapy equipment during operation. Utility Model Content

[0006] The purpose of this invention is to provide a cooling system and a proton radiotherapy device that can improve the overall stability of the proton radiotherapy device during operation.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A cooling system is used to cool a proton therapy device, which includes a refrigeration compressor, an accelerator, and a radio frequency power amplifier. The cooling system includes:

[0009] A first heat exchanger is configured to correspond to the compressor for cooling the compressor;

[0010] A second heat exchanger is configured to be set up in correspondence with the accelerator to cool the accelerator;

[0011] A third heat exchanger is configured to be set up in correspondence with the RF power amplifier to cool the RF power amplifier;

[0012] The bypass valve includes a first end for connecting to the municipal tap water supply, a second end for connecting to the first heat exchanger, and a third end for connecting to the compressor; the bypass valve is used to control the compressor to connect to the first heat exchanger when the first heat exchanger is working normally, or to connect to the municipal tap water supply when the first heat exchanger malfunctions, or when the temperature or flow rate of the cooling medium is abnormal.

[0013] The cooling facility is connected to the first heat exchanger, the second heat exchanger, and the third heat exchanger to supply cooling water to the first heat exchanger, the second heat exchanger, and the third heat exchanger.

[0014] Optionally, the cooling system further includes a power distribution module, which is connected to the first heat exchanger, the second heat exchanger, and the third heat exchanger.

[0015] Optionally, the cooling system further includes a control module, which is connected to the first heat exchanger, the second heat exchanger, the third heat exchanger, the power distribution module, and the bypass valve.

[0016] Optionally, the first heat exchanger, the second heat exchanger, and the third heat exchanger are all equipped with deionized water tanks.

[0017] The proton radiotherapy device includes a compressor, an accelerator, and a radio frequency power amplifier, and also includes the aforementioned cooling system. A first heat exchanger is configured corresponding to the compressor to cool the compressor; a second heat exchanger is configured corresponding to the accelerator to cool the accelerator; and a third heat exchanger is configured corresponding to the radio frequency power amplifier to cool the radio frequency power amplifier.

[0018] Optionally, there are multiple compressors, and the multiple compressors supply and return water through a first water distribution drain, which is connected to a bypass valve.

[0019] Optionally, the proton radiotherapy device further includes a mounting frame, on which the compressor is mounted, and the first heat exchanger, the second heat exchanger, and the third heat exchanger are all located below the compressor.

[0020] Optionally, the cooling system further includes a control module, which is mounted on the mounting bracket and connected to the first heat exchanger, the second heat exchanger, and the third heat exchanger.

[0021] Optionally, the mounting bracket is provided with casters; and / or

[0022] Anchor bolts are provided on the mounting bracket.

[0023] Optionally, the proton radiotherapy device further includes a second water distribution channel, through which the first heat exchanger, the second heat exchanger, and the third heat exchanger are connected to the cooling facility.

[0024] The beneficial effects of this utility model are:

[0025] The cooling system and proton therapy equipment include a first heat exchanger for the compressor, which cools the compressor; a second heat exchanger for the accelerator, which cools the accelerator; and a third heat exchanger for the radio frequency power amplifier, which cools the radio frequency power amplifier. This design allows the cooling of the compressor, accelerator, and radio frequency power amplifier to operate independently. Even if the cooling of one component temporarily fails, it will not affect the cooling of the other two, improving the stability of the proton therapy equipment during operation. It also facilitates independent handling of each component during routine maintenance and repair of the proton therapy equipment.

[0026] Meanwhile, the cooling system and proton therapy equipment include a bypass valve. One end of the bypass valve is configured to connect to the municipal water supply, and the other end is connected to the first heat exchanger. The bypass valve can control the connection between the compressor and the first heat exchanger or the municipal water supply. This configuration allows the compressor to be connected to the municipal water supply via the bypass valve when the first heat exchanger corresponding to the compressor fails, using the municipal water supply as a backup cooling method to keep the compressor cool and further reduce the possibility of the superconducting magnet malfunctioning. Alternatively, when the compressor detects excessively high water temperature, the bypass valve can be used to connect the compressor to the municipal water supply to keep the compressor cool and further reduce the possibility of the superconducting magnet malfunctioning.

[0027] Because the cooling water supplied by the on-site cooling facilities is unreliable, the water quality and supply are uncontrollable for proton therapy equipment. However, proton therapy equipment has very high requirements for the conductivity, pH value, and temperature of the cooling water. This cooling system adds a heat exchanger as isolation between the on-site cooling facilities, compressor, and superconducting magnet, effectively ensuring the long-term reliable operation of the proton therapy equipment.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment provides a proton radiotherapy device in which each part to be cooled is equipped with a heat exchanger that works independently with it. The cooling function of each part to be cooled is independent of each other. Even if the cooling function of one part to be cooled fails, it will not affect the cooling function of the other parts to be cooled, thereby improving the overall stability of the proton radiotherapy device.

[0041] Specifically, see Figures 1-3 The proton therapy equipment includes a compressor 10, an accelerator 20, and a radio frequency amplifier 30.

[0042] Furthermore, the proton therapy equipment also includes a superconducting magnet 50.

[0043] The compressor 10 is a cryogenic compressor used to compress helium gas into liquid helium, which provides an ultra-low temperature environment for the superconducting magnet 50. The superconducting magnet 50 can generate a strong magnetic field in this ultra-low temperature environment, guiding the movement of protons.

[0044] Accelerator 20 is used to accelerate protons to a high-energy state for precise irradiation of tumors.

[0045] The RF power amplifier 30 is an important part of the RF system, which is used to accelerate proton beams.

[0046] The compressor 10, accelerator 20, and radio frequency power amplifier 30 all generate a large amount of heat during operation, meaning they are all components that need to be cooled. To ensure the stability of the proton radiotherapy equipment, it is necessary to cool down the compressor 10, accelerator 20, and radio frequency power amplifier 30.

[0047] In order to cool the compressor 10, accelerator 20, and radio frequency power amplifier 30, the proton radiotherapy equipment in this embodiment also includes a cooling system. The cooling system is used to cool the proton radiotherapy equipment.

[0048] Specifically, the cooling system includes a first heat exchanger 1, a second heat exchanger 2, a third heat exchanger 3, a bypass valve 4, and cooling facilities (not shown in the figure).

[0049] The first heat exchanger 1 is configured to correspond to the compressor 10 for cooling the compressor 10.

[0050] The second heat exchanger 2 is configured to correspond to the accelerator 20 for cooling the accelerator 20.

[0051] The third heat exchanger 3 is configured to correspond with the RF power amplifier 30 to cool the RF power amplifier 30. The accelerator 20 can be understood as excluding the compressor 10 and the accelerator body of the RF system.

[0052] One end of the bypass valve 4, the first end, is configured to connect to the municipal water supply, and the other end, the second end, is connected to the first heat exchanger 1. The bypass valve 4 can control the compressor 10 to connect to either the first heat exchanger 1 or the municipal water supply. The bypass valve 4 also includes a third end for connecting to the compressor 10. That is, by controlling the bypass valve 4, the compressor 10 can selectively connect to either the municipal water supply or the first heat exchanger 1. The bypass valve 4 controls the compressor 10 to connect to the first heat exchanger 1 when the first heat exchanger 1 is operating normally, or to connect to the municipal water supply when the first heat exchanger 1 malfunctions, or the cooling medium temperature is abnormal, or the flow rate is abnormal.

[0053] Optionally, the bypass valve 4 is an electric valve, installed in the supply and return water lines of the compressor 10.

[0054] The cooling facility is connected to the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 to supply cooling water to the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3.

[0055] Optionally, the cooling facility is a water tank equipped with a water pump.

[0056] That is, in the proton radiotherapy equipment, the cooling facility supplies cooling water to the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3. The first heat exchanger 1 is correspondingly set to the compressor 10 to cool the compressor 10; the second heat exchanger 2 is correspondingly set to the accelerator 20 to cool the accelerator 20; and the third heat exchanger 3 is correspondingly set to the radio frequency power amplifier 30 to cool the radio frequency power amplifier 30.

[0057] The cooling system provided in this embodiment includes a first heat exchanger 1 for cooling the compressor 10; a second heat exchanger 2 for cooling the accelerator 20; and a third heat exchanger 3 for cooling the radio frequency power amplifier 30. This configuration ensures that the cooling of the compressor 10, accelerator 20, and radio frequency power amplifier 30 operates independently. Even if the cooling of one component temporarily fails, it will not affect the cooling of the other two, thus improving the stability of the proton radiotherapy equipment during operation. It also facilitates independent handling of each component during routine maintenance and repair of the proton radiotherapy equipment.

[0058] Meanwhile, the cooling system includes a bypass valve 4, one end of which is configured to connect to the municipal tap water supply, and the other end to the first heat exchanger 1. The bypass valve 4 can control the compressor 10 to connect to either the first heat exchanger 1 or the municipal tap water supply. With this configuration, if the first heat exchanger 1, which corresponds to the compressor 10, fails, the bypass valve 4 can control the compressor 10 to connect to the municipal tap water supply, using the municipal tap water as a backup cooling method for the compressor 10, thus keeping the compressor cool and preventing or further reducing the possibility of the superconducting magnet 50 losing its quench. Alternatively, if the compressor 10 detects excessively high water temperature, the bypass valve 4 can control the compressor 10 to connect to the municipal tap water supply, keeping the compressor cool and preventing or further reducing the possibility of the superconducting magnet 50 losing its quench.

[0059] Because the cooling water supplied by the on-site cooling facilities is unreliable, the water quality and supply are uncontrollable for proton therapy equipment. However, proton therapy equipment has very high requirements for the conductivity, pH value, and temperature of the cooling water. This cooling system adds a heat exchanger as isolation between the on-site cooling facilities, compressor 10, and superconducting magnet 50, effectively ensuring the long-term reliable operation of the proton therapy equipment.

[0060] Each of the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 is equipped with a deionized water tank. The cooling water provided by the cooling system, i.e., external cooling water, cools the water in the deionized water tank. The water in the deionized water tank can exchange heat with the parts of the proton radiotherapy equipment that need to be cooled, thereby cooling and lowering the temperature of those parts.

[0061] Of course, in other embodiments, a heat exchanger is added for each additional part to be cooled.

[0062] Furthermore, in this embodiment, the cooling system also includes a power distribution module 5, which is connected to the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3.

[0063] Specifically, in this embodiment, the power distribution module 5 is powered by an uninterruptible power supply (UPS). The power distribution module 5 is capable of supplying power to the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3.

[0064] Furthermore, in this embodiment, the cooling system also includes a control module 6, which is connected to the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3, the power distribution module 5, and the bypass valve 4.

[0065] Specifically, the power distribution module 5 is connected to the control module 6, thereby enabling the power distribution module 5 to supply power to the control module 6.

[0066] The control module 6 can control the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3, and the bypass valve 4.

[0067] Specifically, in the proton radiotherapy equipment, the power distribution module 5 is connected to the compressor 10 and supplies power to the compressor 10; the control module 6 is connected to the compressor 10 to control the operation of the compressor 10.

[0068] Specifically, in the proton radiotherapy equipment, there are multiple compressors 10. The multiple compressors 10 are supplied with water and returned water through the first water distribution valve, which is connected to the bypass valve 4.

[0069] That is, when the bypass valve 4 is open, the municipal tap water flows through the first water distribution drain to multiple compressors 10, thereby cooling down the multiple compressors 10.

[0070] Furthermore, in this embodiment, the proton radiotherapy equipment also includes a second water distribution channel, through which the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 are connected to the cooling facility. The second water distribution channel enables the on-site cooling facility to supply cooling water to the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3.

[0071] Further, see Figure 2 and Figure 3 In this embodiment, the proton radiotherapy device also includes a mounting frame 40. The compressor 10 is mounted on the mounting frame 40, and the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 are all located below the compressor 10.

[0072] Optionally, the mounting bracket 40 is made of aluminum profile.

[0073] By setting up the mounting bracket 40, the mounting bracket is placed outside the strong magnetic field, thereby reducing the influence of the residual magnetic field on the compressor 10 mounted on the mounting bracket 40, and also reducing the influence of the residual magnetic field on the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3 located below the compressor 10.

[0074] The compressor 10 and multiple heat exchangers are arranged vertically, making the overall structure of this part compact and safe, saving the floor space occupied by the proton radiotherapy equipment, and also making the operation of the compressor 10 and multiple heat exchangers simple and quick when replacement is needed.

[0075] Meanwhile, multiple compressors 10 are positioned close to the first heat exchanger 1, which minimizes the power and signal loss of the compressors and reduces the amount of water required for cooling.

[0076] Optionally, the mounting bracket 40 includes a lower mounting position and an upper mounting position, with the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3 all mounted on the lower mounting position; and the multiple compressors 10 all mounted on the upper mounting position.

[0077] Specifically, in this embodiment, the control module 6 of the cooling system is installed on the mounting bracket 40, and the control module 6 is connected to the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3.

[0078] Furthermore, the bypass valve 4 and the power distribution module 5 are also mounted on the mounting bracket 40, improving the product integration.

[0079] Optionally, see Figure 4 The mounting bracket 40 is provided with rollers 401; and / or

[0080] Anchor bolts 402 are provided on the mounting bracket 40.

[0081] Specifically, in this embodiment, the mounting frame 40 is provided with rollers 401 and anchor bolts 402. The rollers 401 facilitate the movement of the mounting frame 40. The anchor bolts 402 can be adjusted to abut against the ground after the mounting frame 40 is moved into place, thereby restricting the movement of the mounting frame 40.

[0082] The proton radiotherapy equipment provided in this embodiment has a first heat exchanger 1, a second heat exchanger 2, a third heat exchanger 3, and multiple compressors 10 all connected to a power distribution module 5. At the same time, the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3, and multiple compressors 10 are all connected to a control module 6 via low-voltage cables. The control module 6 monitors all compressors 10, the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3, and the relays in the bypass valve 4.

[0083] For example, the working process of the cooling system provided in this embodiment is as follows:

[0084] The power distribution module 5 distributes three-phase power provided by the uninterruptible power supply to each compressor 10, as well as the first heat exchanger 1, the second heat exchanger 2, and the third heat exchanger 3. Simultaneously, the power distribution module 5 converts the voltage to supply power to the control module 6. The control module 6 monitors the water flow rate and temperature within each compressor 10 via a low-voltage cable. When a compressor 10 or the first heat exchanger 1 malfunctions, the bypass valve 4 is activated, and a signal is sent to the cooling system's control software. Similarly, when the second heat exchanger 2 or the third heat exchanger 3 malfunctions, the control module 6 also sends a signal to the cooling system's control software.

[0085] During cooling, the cooling water supplied by the cooling facility flows through the primary side of the heat exchanger inside each heat exchanger and exchanges heat with the water (deionized internal water) on the secondary side of the heat exchanger.

[0086] The cooling system uses tap water as a safety backup cooling solution for the compressor 10 through the bypass valve 4, ensuring that the compressor 10 can maintain stable cooling in case of emergencies.

[0087] Under normal operating conditions, secondary water from the first heat exchanger flows into the compressor 10. When the first heat exchanger 1 malfunctions, the bypass valve 4 opens, causing the compressor 10 to switch to tap water supply and return.

[0088] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
