[0022] In the embodiments of the present invention, identical reference numerals denote identical components, and for the sake of brevity, detailed descriptions of identical components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of the present invention, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings, are merely illustrative and do not constitute any limitation on the present invention.

[0023] The term “plurality” used in the present invention refers to two or more (including two).

[0024] The gyrotron is a key high-power millimeter-wave / terahertz wave source, primarily used for electron cyclotron resonance heating (ECRH) and current drive (ECCD). It is a core technology for heating and controlling plasmas in magnetic confinement fusion systems (such as tokamaks and stellarators). A gyrotron consists of multiple subcomponents, each equipped with a cooling element to cool the subcomponents. The cooling system cools the cooling medium discharged from the manifold, which is then circulated back to the manifold.

[0025] The following combination Figures 1 to 4 The manifold 100 for a cooling system of a microwave heating device according to the present invention will be described.

[0026] like Figures 1 to 4 As shown, the manifold 100 for the cooling system of a microwave heating device according to the first embodiment of the present invention includes a water supply pipe group 10 and a water collection pipe group 20. The microwave heating device 700 in the embodiment of the present application can be an electron gyrotron, an ion gyrotron, a klystron, etc.

[0027] The water supply pipe assembly 10 includes a water supply main 101 and multiple water supply branches 102. The water inlet end 1011 of the water supply main 101 is used to connect to the water supply end of the cooling system. The water supply main 101 is connected to the water inlet ends of multiple water supply branches 102. The water inlet ends of the water supply branches 102 are equipped with water supply valves 1021. The water supply valves 1021 are used to control the on and off of the water supply branches 102. Specifically, the water supply valves 1021 can be ball valves.

[0028] The water collection pipe group 20 includes a water collection main pipe 201 and multiple water collection branch pipes 202. The water outlet end 2011 of the water collection main pipe 201 is used to connect to the return water end of the cooling system. The water collection main pipe 201 is connected to the water outlet ends of multiple water collection branch pipes 202. The water outlet ends of the water collection branch pipes 202 are provided with water collection valves 2021. The water collection valves 2021 are used to control the on and off of the water collection branch pipes 202. Specifically, the water collection valves 2021 can be ball valves.

[0029] For example, the cooling system may be a water cooling system or other liquid cooling system to reduce the temperature of the coolant after cooling the subcomponents.

[0030] The first water outlet end 1022 of the water supply branch pipe 102 and the second water inlet end 2022 of the water collection branch pipe 202 are respectively connected to the ends of cooling elements, wherein the cooling elements are used to cool the subcomponents of the microwave heating device 700. It should be noted that the microwave heating device 700 generally includes multiple subcomponents, each of which is equipped with at least one cooling element, which is used to exchange heat with the subcomponent to cool the corresponding subcomponent.

[0031] Specifically, the water supply main 101 is connected to the water supply end of the cooling system, transporting the cooling medium flowing through the cooling system to the various water supply branches 102. The cooling medium is then transported to the cooling elements through the various water supply branches 102, thereby cooling the various subcomponents of the microwave heating device 700. The cooling medium flowing through the cooling elements is then collected by the various water collection branches 202 and collected by the water collection main 201. From there, it is transported to the cooling system, completing the circulating cooling process. The number of water supply branches 102 and water collection branches 202 can be designed based on actual needs and is not specifically limited here.

[0032] At least one of the water supply branch pipe 102 and the water collection branch pipe 202 is provided with an exhaust branch pipe 30 , and the exhaust branch pipe 30 is provided with an exhaust valve 301 .

[0033] Among them, only the water supply branch pipe 102 is provided with an exhaust branch pipe 30, or only the water collection branch pipe 202 is provided with an exhaust branch pipe 30, or both the water supply branch pipe 102 and the water collection branch pipe 202 are provided with an exhaust branch pipe 30. When the exhaust valve 301 on the exhaust branch pipe 30 is opened, the gas in the branch can be discharged to prevent gas accumulation from affecting the stability of system operation.

[0034] In a specific usage scenario, a cooling component is provided on a sub-component. When the sub-component needs to be repaired, the water supply valve 1021 of the water supply branch pipe 102 and the water collection valve 2021 of the water collection branch pipe 202 connected to the cooling component can be closed, so that the water supply branch pipe 102 is not connected to the water supply main pipe 101, and the water collection branch pipe 202 is not connected to the water collection main pipe 201. Then, the cooling medium in the water collection branch pipe 202, the water supply branch pipe 102 and the cooling component is drained, and finally the water collection branch pipe 202, the water supply branch pipe 102 and the cooling component are separated to facilitate the repair of the sub-component.

[0035] After the inspection is complete, the water supply branch pipe 102, the water collection branch pipe 202, and the cooling element are connected, and the water supply valve 1021 and the water collection valve 2021 are opened, so that the water supply main pipe 101 and the water supply branch pipe 102 are connected, and the water collection main pipe 201 and the water collection branch pipe 202 are connected. The cooling medium is introduced into the water supply branch pipe 102, the water collection branch pipe 202, and the cooling element. During this process, gas can be discharged from the exhaust valve 301 of the exhaust branch pipe 30 until the cooling medium is discharged from the exhaust valve 301, indicating that the exhaust is complete. At this time, the exhaust valve 301 can be closed, allowing the manifold 100, the cooling element, and the cooling system to enter normal operation. The branch formed by the sequentially connected water supply branch pipe 102, the cooling element, and the water collection branch pipe 202 can reduce the gas retention in the branch by setting the exhaust branch pipe 30. The exhaust process is simple and convenient to operate and is unlikely to affect other branches.

[0036] According to the embodiment of the present invention, the manifold 100 for the cooling system of a microwave heating device is provided with an exhaust branch 30 on at least one of the water supply branch 102 and the water collecting branch 202, so that the branches formed by the water supply branch 102, the cooling element and the water collecting branch 202 connected in sequence can be exhausted separately, thereby reducing the possibility of gas entering other water supply branch 102 and water collecting branch 202, which is conducive to ensuring the stable heat exchange effect of other branches. In addition, the exhaust operation is simple and convenient, and the gas in the branch can be discharged to prevent gas accumulation from affecting the stability of system operation.

[0037] In some embodiments of the present invention, the water supply branch pipe 102 is located above the water supply main pipe 101, the water collection branch pipe 202 is located above the water collection main pipe 201, and the exhaust valve 301 is located no lower than the locations of the water supply branch pipe 102 and the water collection branch pipe 202.

[0038] For example, the highest point of the water supply branch pipe 102 may be located higher than the highest point of the water collection branch pipe 202 ; wherein the exhaust branch pipe 30 may be connected to the water supply branch pipe 102 , or the exhaust branch pipe 30 may also be connected to the water collection branch pipe 202 .

[0039] Alternatively, the highest point of the water supply branch pipe 102 may be located lower than or equal to the highest point of the water collection branch pipe 202 , wherein the exhaust branch pipe 30 may be connected to the water supply branch pipe 102 , or the exhaust branch pipe 30 may be connected to the water collection branch pipe 202 .

[0040] Specifically, the exhaust branch pipe 30 may extend vertically, and the exhaust valve 301 may be provided at the upper end of the exhaust branch pipe 30 so that the spatial position of the exhaust valve 301 is as high as possible, so that the gas can more easily reach the position of the exhaust valve 301 .

[0041] The water supply branch pipe 102 is located above the water supply main pipe 101, and the water collecting branch pipe 202 is located above the water collecting main pipe 201. The position of the microwave heating device 700 is usually higher, and the water supply branch pipe 102 and the water collecting branch pipe 202 are arranged above to reduce the layout length of the cooling part and make the space layout more reasonable.

[0042] In the above embodiment, the position of the exhaust valve 301 is not lower than the positions of the water supply branch pipe 102 and the water collection branch pipe 202, so that the gas in the branch can be fully discharged from the exhaust valve 301, thereby avoiding gas accumulation affecting the stable operation of the system; at the same time, the water supply branch pipe 102 and the water collection branch pipe 202 are provided with longer lengths, which facilitates the arrangement of monitoring devices to monitor the operating status of the branch and meet the operating requirements of the microwave heating device 700.

[0043] In some embodiments of the present invention, reference may be made to Figure 1 and Figure 4 The water inlet end of the water supply branch pipe 102 is connected to the first drainage branch pipe 103, the first drainage branch pipe 103 is provided with a first drainage valve 1031, and the first drainage branch pipe 103 is located on the downstream side of the water supply valve 1021; the water outlet end of the water collection branch pipe 202 is connected to the second drainage branch pipe 203, the second drainage branch pipe 203 is provided with a second drainage valve 2031, and the second drainage branch pipe 203 is located on the upstream side of the water collection valve 2021.

[0044] When the water supply branch pipe 102 needs to be drained, the first drain valve 1031 can be opened. When the water collection branch pipe 202 needs to be drained, the second drain valve 2031 can be opened. By providing the first drain branch pipe 103 and the second drain branch pipe 203, when a sub-component is to be repaired, only the corresponding water supply branch pipe 102 and water collection branch pipe 202 can be drained without draining other branches, thereby reducing the amount of cooling medium discharged and maintaining the stable operation of other branches.

[0045] The water supply main 101 is equipped with a third drain valve 1012, and the water collection main 201 is equipped with a fourth drain valve 2012. The third drain valve 1012 is located on the side of the multiple water supply branch pipes 102 away from the water inlet end 1011 of the water supply main 101, while the fourth drain valve 2012 is located on the side of the multiple water collection branch pipes 202 away from the water outlet end 2011 of the water collection main 201. When draining the water supply main 101 or the entire water supply pipe assembly, the third drain valve 1012 can be opened, and when draining the water collection main 201 or the entire water collection pipe assembly, the fourth drain valve 2012 can be opened. By providing the third drain valve 1012 on the water supply main 101 and the fourth drain valve 2012 on the water collection main 201, the water supply pipe assembly 10 and the water collection pipe assembly 20 can be drained quickly and completely.

[0046] Specifically, the third drain valve 1012 and the fourth drain valve 2012 may be ball valves.

[0047] In some embodiments of the present invention, reference may be made to Figure 4 The water supply branch pipe 102 is also provided with a flow regulating valve 104 and a flow meter 105 . The flow regulating valve 104 is provided on the downstream side of the water supply valve 1021 , and the flow meter 105 is provided on the downstream side of the flow regulating valve 104 .

[0048] In the above embodiment, the flow control valve 104 cooperates with the flow meter 105 to achieve a relatively accurate flow control function for the branch circuit to meet the different cooling requirements of each subcomponent.

[0049] Specifically, flowmeter 105 is a float flowmeter, allowing staff to monitor the flow rate of water supply branch pipe 102 on-site. Alternatively, flowmeter 105 can be an electromagnetic flowmeter connected to control system 600, allowing control system 600 to monitor the flow rate of water supply branch pipe 102 in real time. Flow control valve 104 can be a shutoff valve, and each water supply branch pipe 102 is equipped with a flow control valve 104 to adjust the flow rate and pressure parameters of the cooling medium entering each cooling element.

[0050] In some embodiments of the present invention, reference may be made to Figure 4 The water supply branch pipe 102 is provided with a first temperature transmitter 106, and the water collection branch pipe 202 is provided with a second temperature transmitter 204. The first temperature transmitter 106 and the second temperature transmitter 204 are used to be connected to the control system 600. Therefore, the temperature of the water supply branch pipe 102 and the water collection branch pipe 202 can be monitored in real time by the control system 600 to ensure the safe and efficient operation of the microwave heating device 700.

[0051] In some embodiments of the present invention, reference may be made to Figure 4The water supply branch pipe 102 is also provided with a flow regulating valve 104 and a flow meter 105 , and the water collection branch pipe 202 is provided with a second temperature transmitter 204 , which is used to be connected to the control system 600 .

[0052] In some embodiments of the present invention, the water supply branch pipe 102 is also provided with a flow regulating valve 104 and a flow meter 105, the water supply branch pipe 102 is provided with a first temperature transmitter 106, and the water collection branch pipe 202 is provided with a second temperature transmitter 204. The first temperature transmitter 106 and the second temperature transmitter 204 are used to be connected to the control system 600.

[0053] In addition, the internal energy change of the cooling medium can be calculated based on the temperature of the cooling medium before it enters the manifold 100 and the temperature difference of the cooling medium in the water collection branch 202, or the temperature difference between the cooling medium in the water supply branch 102 and the cooling medium in the water collection branch 202, combined with the flow data of the water supply branch 102, and then the microwave power is obtained based on the corresponding time. Therefore, the manifold 100 of the embodiment of the present application is also beneficial for providing support for the microwave power measurement of the microwave heating device 700.

[0054] In some embodiments, reference may be made to Figure 5 The control system 600 compares the temperature detected by the second temperature transmitter 204 with a preset temperature threshold. If the temperature detected by the second temperature transmitter 204 exceeds the preset temperature threshold, it generates a control instruction to stop the microwave heating device 700 and generates a warning signal. This helps reduce the possibility of overheating and damage to the microwave heating device 700. After receiving the warning signal, personnel can promptly inspect and repair the corresponding components.

[0055] In some embodiments of the present invention, both the water supply branch pipe 102 and the water collection branch pipe 202 are provided with a pressure transmitter 40 , and the pressure transmitter 40 is used to communicate with the control system 600 .

[0056] Thus, the control system 600 can monitor pressure changes in the water supply branch pipe 102 and the water collection branch pipe 202 in real time, reducing the possibility of damage to the microwave heating device 700 due to excessive pressure. Furthermore, each water supply branch pipe 102 and water collection branch pipe 202 is equipped with a pressure transmitter 40, allowing for rapid location of a particular branch pipe when pressure increases or decreases. Furthermore, the pressure differential between the water supply branch pipe 102 and the water collection branch pipe 202 can be used to determine whether a pipe is damaged, allowing for timely detection of damaged pipes, thereby improving system operational safety.

[0057] Specifically, the pressure transmitter 40 has a built-in physical quantity sensing module and a signal conversion module. It performs analog-to-digital conversion of the pressure physical quantity through the piezoresistive effect, generates a standardized electrical signal, and transmits it to the control system 600, thereby completing dynamic monitoring of the branch water supply pressure parameters and return water pressure parameters. Specifically, a ball valve can be installed between the pressure transmitter 40 and the water supply branch pipe 102, and a ball valve can be installed between the pressure transmitter 40 and the water collection branch pipe 202. When the pressure transmitter 40 needs to be disassembled for maintenance, the ball valve can be closed without draining the cooling medium in the manifold 100, improving the convenience of disassembly and maintenance. When in normal use, the ball valve can be opened.

[0058] In some embodiments, reference may be made to Figure 5 The control system 600 compares the pressure detected by the pressure transmitter 40 with a preset pressure threshold. If the pressure detected by the pressure transmitter 40 exceeds the preset pressure threshold, it generates a control instruction to stop the microwave heating device 700 and generates a warning signal. This helps reduce the possibility of overpressure damage to the microwave heating device. After receiving the warning signal, personnel can promptly inspect and repair the corresponding components.

[0059] In some embodiments of the present invention, reference may be made to Figures 1 to 4 The bracket 50 is equipped with a roller 501 to make the bracket 50 movable, and the bracket 50 is equipped with a fixing device 502 to fix the position of the bracket 50. The water supply pipe group 10 and the water collecting pipe group 20 are both arranged on the bracket 50.

[0060] It should be noted that the gyrotron or other microwave heating device 700 usually needs to be tested on multiple experimental platforms during the experimental research stage. In the relevant technology, a fixed manifold needs to be configured on each experimental platform, and the manifolds on multiple experimental platforms also need to be regularly inspected and maintained, which greatly increases the research and testing costs.

[0061] This application utilizes a bracket 50, onto which the water supply pipe assembly 10 and the water collection pipe assembly 20 are integrated. The bracket 50 is designed to be movable, allowing the manifold 100 to be flexibly moved to different experimental platforms as needed. Once in place, it can be secured using a fixture 502. This design significantly reduces costs and is well suited to the needs of switching between multiple experimental stations in a microwave heating device 700 (e.g., a gyrotron).

[0062] Furthermore, when a new transmission line water distribution pipeline is needed, the entire manifold 100 can be directly added without the need for additional welding, fixing, or assembly steps, facilitating rapid expansion of the pipeline. When off-site maintenance is required, the manifold 100 of the present application can be simply separated from the corresponding pipeline and then removed, eliminating the complex step of disassembling it from the supporting component and making the operation more convenient.

[0063] By providing the fixing device 502 , after the manifold 100 is moved to a target position, the manifold 100 can be fixed at the target position by the fixing device 502 to prevent the manifold 100 from being accidentally moved.

[0064] By fixing the water supply pipe assembly 10 and the water collecting pipe assembly 20 to the bracket 50 , the structures of the water supply pipe assembly 10 and the water collecting pipe assembly 20 are more stable, and are convenient for installation and maintenance.

[0065] Exemplarily, the roller 501 can be a rubber wheel body so as to have good shock absorption performance. The rubber wheel body can freely change direction 360°, so as to facilitate moving the manifold 100 to the desired position; the fixing device 502 is installed on the roller 501, which can fix the roller 501 on the ground to prevent the manifold 100 from malfunctioning.

[0066] For example, the fixing device 502 can be a wheel brake, and the roller 501 can include a protective shell, the wheel brake is connected to the protective shell, and a reset component is provided on the inner wall of the protective shell close to the wheel brake. The reset component is used to reset the wheel brake, and a clip buckle is integrally connected to one side of the bottom inner wall of the wheel brake, and an extruded rubber is bonded to the inner wall of one side of the bottom inner wall of the wheel brake, and the outer walls of the clip buckle and the extruded rubber form a friction fit with the outer wall of the roller 501.

[0067] In some embodiments of the present invention, reference may be made to Figure 1 The bracket 50 includes a first frame 503, a second frame 504, and a connecting frame 505. The first frame 503 and the second frame 504 are spaced apart in the vertical direction and connected by the connecting frame 505. The roller 501 is mounted on the bottom of the first frame 503, the water supply main pipe 101 and the water collection main pipe 201 are mounted on the top of the first frame 503, and the second frame 504 is located between the water supply branch pipe 102 and the water collection branch pipe 202. The water supply branch pipe 102 and the water collection branch pipe 202 are mounted on the second frame 504. As a result, the entire structure of the bracket 50 is stable and not easily deformed. It can well adapt to the spatial arrangement of the water supply pipe group 10 and the water collection pipe group 20. When the cooling element is connected to the water supply branch pipe 102 and the water collection branch pipe 202, it is unlikely to interfere with the bracket 50.

[0068] Exemplarily, the first frame 503 and the second frame 504 can both include multiple horizontal pipes that are arranged perpendicularly to each other and connected to each other, so that the first frame 503 and the second frame 504 are not easily deformed, and provide good support for the water collection main pipe 201, the water collection branch pipe 202, the water supply main pipe 101 and the water supply branch pipe 102.

[0069] For example, the bracket 50 may be made of stainless steel, which is lightweight, high in strength, and has a long service life.

[0070] In some embodiments of the present invention, reference may be made to Figure 2 and Figure 4 The water supply branch pipe 102 and the water collection branch pipe 202 are arranged spaced apart along the first direction F1, and the water outlet end 1022 of the water supply branch pipe 102 and the water inlet end 2022 of the water collection branch pipe 202 are oriented in the same direction and staggered along the second direction F2, and the second direction F2 is perpendicular to the first direction F1.

[0071] For example, the water outlet end 1022 of the water supply branch pipe 102 and the water inlet end 2022 of the water collection branch pipe 202 are both oriented to one side in the horizontal direction. Figure 1 The left and right directions in the second direction F2 are Figure 1 In the vertical direction, the outlet end 1022 of the water supply branch pipe 102 and the inlet end 2022 of the water collection branch pipe 202 are staggered up and down. Alternatively, the first direction F1 is Figure 1 The left and right directions in the second direction F2 are Figure 1 In the front-to-back direction, the water outlet end 1022 of the water supply branch pipe 102 and the water inlet end 2022 of the water collecting branch pipe 202 are staggered front to back.

[0072] In the above embodiment, the first outlet end 1022 of the water supply branch pipe 102 and the second inlet end 2022 of the water collection branch pipe 202 are oriented in the same direction, facilitating connection to the cooling element without requiring significant bending of the cooling element. The first outlet end 1022 of the water supply branch pipe 102 and the second inlet end 2022 of the water collection branch pipe 202 are staggered along the second direction F2, thereby preventing interference between the pipe connected to the first outlet end 1022 of the water supply branch pipe 102 and the pipe connected to the second inlet end 2022 of the water collection branch pipe 202.

[0073] A specific embodiment is given below to illustrate the manifold 100 for the cooling system of a microwave heating device according to an embodiment of the present invention. It should be noted that this embodiment does not constitute a limitation to the present invention.

[0074] It should be noted that the gyrotron is a key high-power millimeter-wave / terahertz wave source, primarily used for electron cyclotron resonance heating (ECRH) and current drive (ECCD). Each of its subcomponents is equipped with a cooling element to cool the subcomponents. The cooling system cools the cooling medium discharged from the manifold 100, which then flows back to the manifold 100.

[0075] You can refer to Figures 1 to 5 The manifold 100 includes a water supply pipe group 10 , a water collection pipe group 20 and a bracket 50 .

[0076] The water supply pipe group 10 includes a water supply main 101 and multiple water supply branches 102. The water inlet end 1011 of the water supply main 101 is used to connect to the water supply end of the cooling system. The water supply main 101 is connected to the water inlet ends of multiple water supply branches 102. The water inlet ends of the water supply branches 102 are provided with water supply valves 1021. The water supply valves 1021 are used to control the on and off of the water supply branches 102. The water collecting pipe group 20 includes a water collecting main pipe 201 and multiple water collecting branch pipes 202. The water outlet end 2011 of the water collecting main pipe 201 is used to connect to the return water end of the cooling system. The water collecting main pipe 201 is connected to the water outlet ends of multiple water collecting branch pipes 202. The water outlet ends of the water collecting branch pipes 202 are provided with water collecting valves 2021. The water collecting valves 2021 are used to control the on and off of the water collecting branch pipes 202. The water supply main 101 and the water collection main 201 both extend horizontally. The first water inlet end 1011 of the water supply main 101 and the second water outlet end 2011 of the water collection main 201 are both provided with connecting flanges, i.e., the connecting flanges are provided at one horizontal end of the water supply main 101 and the second water outlet end 2011 of the water collection main 201. Both the first water inlet end 1011 of the water supply main 101 and the second water outlet end 2011 of the water collection main 201 can form curved pipe sections, so that the first water inlet end 1011 of the water supply main 101 and the second water outlet end 2011 of the water collection main 201 face upward, thereby reducing the possibility of interference between the water supply main 101 and the water collection main 201 and the bracket 50 when the water supply main 101 and the water collection main 201 are connected to the cooling system.

[0077] The water supply main 101 is provided with a third drain valve 1012, and the water collection main 201 is provided with a fourth drain valve 2012. The third drain valve 1012 is located on the side of the multiple water supply branch pipes 102 away from the water inlet end 1011 of the water supply main 101, while the fourth drain valve 2012 is located on the side of the multiple water collection branch pipes 202 away from the water outlet end 2011 of the water collection main 201. In other words, the third drain valve 1012 is located at the other horizontal end of the water supply main 101, and the fourth drain valve 2012 is located at the other horizontal end of the water collection main 201. This allows the third drain valve 1012 and the fourth drain valve 2012 to be positioned relatively low, thereby draining the cooling medium from the entire water supply pipe assembly 10 and the water collection pipe assembly 20 as much as possible.

[0078] The water supply main 101 and the water collection main 201 can be fixed to the first frame 503 by a plurality of U-shaped bolts.

[0079] The water supply branch pipe 102 is located above the water supply main pipe 101, the water collection branch pipe 202 is located above the water collection main pipe 201, and the exhaust valve 301 is located no lower than the locations of the water supply branch pipe 102 and the water collection branch pipe 202 to facilitate exhaust.

[0080] The water supply branch pipe 102 and the water collection branch pipe 202 can each include a first portion and a second portion. One end of the first portion is welded to the water supply main pipe 101 or the water collection main pipe 201. The other end of the first portion and one end of the second portion are each provided with a connecting flange. The connecting flange of the first portion and the connecting flange of the second portion are fixed together by a connecting member. The connecting member is arranged around the connecting flange connected to the first portion and the connecting flange connected to the second portion. The inner circumferential surface of the connecting member forms a limiting groove, and the connecting flange is inserted into the limiting groove so that the connecting flange is axially compressed in the limiting groove.

[0081] Specifically, the connecting member includes a first clamping member and a second clamping member. The first clamping member and the second clamping member form an integrally arranged surrounding a connecting flange. One end of the first clamping member is hinged to one end of the second clamping member. The other end of the first clamping member is movably connected to one end of a stud. The other end of the second clamping member is formed with an open slot, through which the stud is inserted. The other end of the stud is connected to a tightening member, which is used to tighten onto the stud. A limiting groove is formed on the inner side surface of the first clamping member and the inner side surface of the second clamping member. The first part and the second part are connected by the connecting member, so that the first part and the second part can be quickly separated and disassembled.

[0082] The first drain valve 1031, water supply valve 1021, second drain valve 2031, water collection valve 2021, flow control valve 104, temperature transmitter, and pressure transmitter 40 are all located in the second section. When maintenance or replacement is required, the connector can be simply disconnected from the connecting flange, and then the first and second sections can be separated. The second section can then be inspected, making it easier to repair or replace the water supply branch pipe 102 and the water collection branch pipe 202.

[0083] The water outlet end 1022 of the water supply branch pipe 102 is located lower than the water inlet end 2022 of the water collection branch pipe 202. Both the water supply branch pipe 102 and the water collection branch pipe 202 include a first section and a second section, which are connected to each other. The first section extends vertically and is connected to the water supply main pipe 101 or the water collection main pipe 201. The second section extends horizontally to facilitate connection with the hose so that the hose does not bend excessively.

[0084] The second section is connected to an exhaust branch pipe 30 , which extends vertically. An exhaust valve 301 is provided at the upper end of the exhaust branch pipe 30 so that the gas in the branch can be discharged as completely as possible.

[0085] The first water outlet end 1022 of the water supply branch pipe 102 and the second water inlet end 2022 of the water collecting branch pipe 202 are respectively used to connect the two ends of the cooling element, which is provided in the sub-component of the vortex tube and is used to take away the heat generated by the sub-component.

[0086] The water inlet end of the water supply branch pipe 102 is connected to the first drainage branch pipe 103, and the first drainage branch pipe 103 is provided with a first drainage valve 1031. The first drainage branch pipe 103 is located on the downstream side of the water supply valve 1021; that is, the water supply valve 1021 is located above the connecting flange of the water supply branch pipe 102, and the first drainage branch pipe 103 is located above the water supply valve 1021. The first drainage branch pipe 103 can drain the water in the water supply branch pipe 102 as much as possible.

[0087] The outlet end of the water collecting branch pipe 202 is connected to the second drainage branch pipe 203, and the second drainage branch pipe 203 is provided with a second drainage valve 2031. The second drainage branch pipe 203 is located on the upstream side of the water collecting valve 2021; that is, the water collecting valve 2021 is located above the connecting flange of the water collecting branch pipe 202, and the second drainage branch pipe 203 is located above the water collecting valve 2021. The second drainage branch pipe 203 can drain the water in the water collecting branch pipe 202 as much as possible.

[0088] The water supply branch pipe 102 is provided with a connecting flange, a water supply valve 1021, a first drain branch pipe 103, a flow control valve 104, a pressure transmitter 40, and a flow meter 105, in the order in which the cooling medium flows. The water supply branch pipe 102 is provided with a first temperature transmitter 106, and the water collection branch pipe 202 is provided with a second temperature transmitter 204. The second temperature transmitter 204 and the pressure transmitter 40 are connected to a control system 600. The control system 600 is configured to compare the temperature detected by the second temperature transmitter 204 with a preset temperature threshold. If the temperature detected by the second temperature transmitter 204 exceeds the preset temperature threshold, the control system 600 generates a control instruction to stop the microwave heating device and generate an alert signal. The control system 600 is configured to compare the pressure detected by the pressure transmitter 40 with a preset pressure threshold. If the pressure detected by the pressure transmitter 40 exceeds the preset pressure threshold, the control system 600 generates a control instruction to stop the microwave heating device and generate an alert signal.

[0089] The bracket 50 is equipped with rollers 501 to enable the bracket 50 to be movable, and the bracket 50 is equipped with a fixing device 502 to fix the position of the bracket 50. The water supply pipe group 10 and the water collection pipe group 20 are both installed on the bracket 50. The bracket 50 includes a first frame 503, a second frame 504, and a connecting frame 505. The first frame 503 and the second frame 504 are arranged spaced apart in the vertical direction and connected by the connecting frame 505. The rollers 501 are installed at the bottom of the first frame 503, the water collection main pipe 201 and the water supply main pipe 101 are installed at the top of the first frame 503, and the second frame 504 is located between the water supply branch pipe 102 and the water collection branch pipe 202. The water supply branch pipe 102 and the water collection branch pipe 202 are installed on the second frame 504.

[0090] The water supply branch pipe 102 and the water collection branch pipe 202 are arranged spaced apart in the horizontal direction, and the water outlet end 1022 of the water supply branch pipe 102 and the water inlet end 2022 of the water collection branch pipe 202 are in the same direction and staggered in the up and down directions, so that the pipes connected to the water outlet end 1022 of the water supply branch pipe 102 and the pipes connected to the water inlet end 2022 of the water collection branch pipe 202 will not interfere with each other.

[0091] The connecting frame 505 may include connecting columns and reinforcing columns connected between the connecting columns and the first frame 503. The first frame 503 and the second frame 504 may each include a first transverse beam extending along a first direction F1 and a second longitudinal beam extending along a second direction F2, with the first transverse beam and the second longitudinal beam arranged perpendicularly. The water supply branch pipe 102 and the water collection branch pipe 202 are also secured to the second frame 504 using U-bolts.

[0092] From the above, the embodiment of the present application provides a manifold 100 with greater flexibility and more comprehensive functions. The manifold 100 is mobile and can flexibly adjust its position according to needs, and is equipped with a fixing device 502 to prevent accidental movement. At the same time, the manifold 100 is provided with monitoring devices such as a pressure transmitter 40, a flow meter 105, and a temperature transmitter to monitor the pressure and flow changes of the water supply pipe group 10 and the water collection pipe group 20 to prevent excessive pressure from damaging the vortex tube.
