Description

Technical Field

[0001] This invention relates to the field of high-voltage power supply technology, and in particular to a solid-state packaging structure for a high-voltage power supply. Background Technology

[0002] A high-voltage generator, also known as a DC high-voltage generator, is the traditional term for a high-voltage power supply, primarily used for insulation and leakage current detection. Currently, there is no strict distinction between high-voltage power supplies and high-voltage generators. High-frequency DC high-voltage generators employ high-frequency voltage multiplier circuits, utilize the latest PW high-frequency pulse width modulation technology, closed-loop adjustment, and large voltage feedback, significantly improving voltage stability. Using high-performance high-power IGBT devices and their driving technology, and based on electromagnetic compatibility theory, employing special shielding, isolation, and grounding measures, the DC high-voltage generator achieves high quality, portability, and the ability to withstand rated voltage discharge without damage.

[0003] Most high-voltage power supplies have rigid encapsulation structures. Vibrations generated during the operation of high-voltage power supplies, as well as vibrations transmitted from the external environment, can easily cause internal circuit components and connections to loosen, leading to faults such as short circuits and leakage, which seriously affect the service life of the equipment.

[0004] Therefore, it is necessary to propose a solid-state packaging structure for high-voltage power supplies to solve the above problems. Summary of the Invention

[0013] Multiple pressure-reducing components are fixedly connected to the top of the interior of the high-voltage power supply box.

[0018] The technical effects and advantages of this invention are as follows:

[0019] In this invention, the elastic liquid bag is filled with a high specific heat capacity fluorinated liquid, which can quickly absorb the heat generated by the circuit board and achieve efficient heat dissipation in conjunction with the circulation component; at the same time, its own flexible material can absorb the vibration transmitted by the operation of the equipment and the outside through deformation, and combined with the limiting effect of the internal pull rope, it can avoid irregular deformation of the liquid bag and ensure uniform support.

[0020] In this invention, the upper and lower circular seats are threaded together. On the one hand, this helps to limit the maximum expansion height of the elastic liquid bag and prevent the liquid bag from over-expanding and breaking. On the other hand, it can use the squeezing reaction force after the elastic liquid bag is filled to avoid vibration causing the two to separate. At the same time, it does not hinder the flexible deformation of the elastic liquid bag and ensures that the vibration reduction function is not affected.

[0021] In this invention, the spring-damped telescopic rod applies flexible downward pressure to the drawer-type circuit assembly through elastic force, and works in conjunction with the elastic liquid bag to achieve double vibration reduction and prevent the assembly from vibrating and shifting. The roller at its bottom works in conjunction with the moving limit groove of the reinforcing plate to roll and reduce resistance when the drawer-type assembly is inserted or removed, making it easy for operators to quickly complete assembly and maintenance. The single combination structure simultaneously meets the requirements of "vibration reduction and limit" and "easy operation", improving the efficiency of equipment assembly and maintenance.

[0022] In this invention, the four hexagonal handles can be rotated to adjust the height of the high-voltage power supply box, which facilitates temporary support for the bottom of the high-voltage power supply box. At the same time, when the coolant inside the elastic liquid bag is recovered, the upper and lower round seats can be threaded together to ensure that there are no gaps between them, which facilitates the formation of rigid support for the bottom of the drawer-type circuit components.

[0023] In the actual operation of this invention, when the fixing screws and clamping nuts are not removed, the drawer-type circuit assembly and the high-voltage power supply box are used as a whole. When the fixing screws and clamping nuts are removed, the drawer-type circuit assembly can be taken out separately, which is convenient for personnel to inspect and maintain.

[0036] This invention provides, for example Figure 1 - Figure 11 The solid-state packaging structure of a high-voltage power supply shown includes a high-voltage power supply housing 1. The high-voltage power supply housing 1 is equipped with a drawer-type circuit assembly. The high-voltage power supply housing 1 is a hollow cuboid structure made of high-strength insulating alloy material, which has good pressure resistance, corrosion resistance and insulation performance. It can effectively isolate external environmental interference and protect the safety of internal components. The drawer-type circuit assembly can slide and be inserted and removed along the inside of the high-voltage power supply housing 1, which is convenient for later assembly, inspection and maintenance without disassembling the entire packaging structure, greatly improving maintenance efficiency.

[0037] The drawer-type circuit assembly includes a first end plate 4 and a second end plate 11. A circuit board 19 is disposed between the opposite sides of the first end plate 4 and the second end plate 11. A first power module 18, an isolation module 36, and a second power module 37 are disposed on the top of the circuit board 19. A display panel 8 and an auxiliary handle 5 are disposed on the first end plate 4. The circuit board 19 is the core circuit carrier of the high-voltage power supply, and various electronic components are integrated on its surface to realize the core functions of power supply and conversion of the high-voltage power supply. The first power module 18 and the second power module 37 are used to provide stable power supply and ensure the normal operation of the high-voltage power supply. The isolation module 36 is used to realize circuit isolation, avoid signal interference between different modules, improve the stability of circuit operation, and prevent module failure from affecting the operation of the overall equipment. Since the first power module 18, the second power module 37, and the isolation module 36 are all existing technologies, they will not be described in detail.

[0038] The other end of the high-voltage power supply box 1 is provided with a plug-in interface 15. Both sides of the plug-in interface 15 are provided with movable slide grooves 13. Both sides of the circuit board 19 are fixedly connected with isolation plates 16. The two isolation plates 16 are provided with sliders 17 on the opposite side. The sliders 17 are slidably installed in the corresponding movable slide grooves 13. The isolation plates 16 are made of insulating material to achieve insulation between the circuit board 19 and the high-voltage power supply box 1, to prevent leakage, and to protect both sides of the circuit board 19. The sliders 17 and the movable slide grooves 13 are adapted to realize the sliding guide of the drawer-type circuit components, to ensure smooth insertion and removal, and to limit the drawer-type circuit components laterally to prevent displacement during vibration.

[0039] The second end plate 11 is fixedly connected to a screw 20 on the side away from the first end plate 4. The screw 20 is provided with a terminal 35 inside. The terminal 35 is connected to the drawer-type circuit assembly. One end of the high-voltage power supply box 1 is provided with an opening. The screw 20 extends out of the opening, and a clamping nut 6 is threaded on the outer side of the extended part of the screw 20.

[0040] In the actual operation of this invention, the screw 20 is made of insulating material and is connected to the terminal 35 and the drawer-type circuit assembly to realize the line connection of the high-voltage power supply and transmit power and signals. When the entire drawer-type circuit assembly is inserted into the plug interface 15, one end of the screw 20 extends out of the opening of the high-voltage power supply box 1. The clamping nut 6 is used to fix the screw 20 on the high-voltage power supply box 1 to ensure connection stability. At the same time, the screw 20 can protect the connection between the terminal 35 and the line, reducing the entry of dust and moisture. The clamping nut 6 also seals the connection.

[0041] The connector 15 has fixing holes 14 at each of its four corners, and the first end plate 4 has fixing screws at each of its four corners. One end of the fixing screw is threaded into the corresponding fixing hole 14.

[0042] In the actual operation of this invention, when the fixing screws and clamping nuts 6 are not removed, the drawer-type circuit assembly and the high-voltage power supply box 1 are used as a whole. When the fixing screws and clamping nuts 6 are removed, the drawer-type circuit assembly can be taken out separately, which is convenient for personnel to inspect and maintain.

[0043] The high-voltage power supply box 1 has four threaded lifting liquid bag mounting seats at the bottom corners. Each of the four liquid bag mounting seats contains an elastic liquid bag 24. The bottom of the high-voltage power supply box 1 is connected to an auxiliary box 7. The auxiliary box 7 contains a circulation component, which is connected to the four elastic liquid bags 24. The elastic liquid bags 24 are filled with coolant and are made of high-temperature resistant, high-pressure resistant, and insulating flexible material. They are filled with high-insulation coolant, which is a fluorinated liquid with high specific heat capacity and high thermal conductivity. It can quickly absorb the heat generated by the operation of the high-voltage power supply and also achieve vibration reduction by utilizing the flexible deformation of the elastic liquid bags 24.

[0044] The auxiliary housing 7 can be detached and connected to the bottom of the high-voltage power supply housing 1 by bolts, which facilitates subsequent disassembly and maintenance. The circulation component and four elastic liquid bags 24 are connected to realize the transportation and recycling of coolant, forming a closed-loop heat dissipation circuit to ensure continuous and stable heat dissipation effect.

[0045] Specifically, each of the four corners of the bottom of the drawer-type circuit assembly is provided with an upper round seat 23. The liquid bag mounting seat includes a threaded rod 10 and a lower round seat 26. The lower round seat 26 and the upper round seat 23 are threaded together. The elastic liquid bag 24 is set inside the lower round seat 26. It should be noted that the threaded end 27 at the top of the lower round seat 26 is only used for the initial positioning of the upper round seat 23 and the lower round seat 26. The threaded engagement is not tightened, and a gap of 1-2mm is reserved.

[0046] A flexible silicone pad is added to the outside of the threaded end 27. After the upper round seat 23 and the lower round seat 26 are positioned, they are attached by the flexible pad, which not only achieves positioning, but also does not affect the vibration reduction effect of the elastic liquid bag 24, thus avoiding the rigid fit from squeezing the elastic liquid bag 24 and causing the vibration reduction function to fail.

[0047] The threaded engagement between the lower circular seat 26 and the upper circular seat 23 helps limit the maximum expansion height of the liquid bag, preventing the elastic liquid bag 24 from over-expanding and rupturing. The squeezing action of the elastic liquid bag 24 acts on the connection between the lower circular seat 26 and the upper circular seat 23, generating reverse pressure to prevent vibration from causing separation between the lower circular seat 26 and the upper circular seat 23, thus ensuring support stability. Specifically, when the elastic liquid bag 24 is fully expanded to a certain height, its top will contact the inner wall of the receiving groove of the upper circular seat 23. At this time, the threads of the upper circular seat 23 and the lower circular seat 26... The matching structure (non-rigid locking) provides a slight limiting force to prevent the elastic liquid bag 24 from over-expanding and breaking. This limiting force only acts on the limit position of the expansion of the elastic liquid bag 24 and does not affect the elastic deformation of the elastic liquid bag 24 during normal filling and compression. Moreover, the compression buffer of the elastic liquid bag 24 during operation (such as the flexible deformation during equipment vibration and the slight expansion and contraction during coolant circulation) will achieve normal buffering effect through the elastic deformation of the silicone flexible pad and the compensation of the reserved gap, and will not cause rigid obstruction due to the threaded mating structure.

[0048] The upper circular seat 23 can be made of thermally conductive material to facilitate the transfer of heat to the elastic liquid bag 24, while also providing top limiting support for the elastic liquid bag 24;

[0049] The circulation assembly includes an insulated infusion pump 33, a storage tank 34, and a four-way diversion valve 22. The insulated infusion pump 33, the storage tank 34, and the four-way diversion valve 22 are all fixedly connected inside the auxiliary housing 7. A hose 21 is provided between the four-way diversion valve 22 and the four elastic liquid bags 24. The four-way diversion valve 22, the insulated infusion pump 33, and the storage tank 34 are connected in sequence through pipes.

[0050] The insulated infusion pump 33 is a miniature insulated gear pump with controllable forward and reverse rotation, providing power for coolant circulation. The reservoir 34 is used to store coolant and has a certain buffer capacity to compensate for coolant loss during circulation and facilitate coolant replenishment. It should be noted that the reservoir 34 is equipped with an openable sealing cover, allowing for the addition or drainage of coolant after the auxiliary housing 7 is disassembled.

[0051] The hose 21 is made of polytetrafluoroethylene (PTFE) insulated hose, which has good flexibility, corrosion resistance and bidirectional flow. The hose 21 is suitable for the delivery and recovery of coolant, while avoiding leakage. It can bend slightly with the deformation of the elastic liquid bag 24 without affecting the vibration reduction of the liquid bag. The insulated delivery pump 33 rotates in both directions to realize the function of outputting and recovering coolant: when the insulated delivery pump 33 rotates in the forward direction, it draws out the coolant from the storage tank 34, distributes it through the four-way diverter valve 22, and delivers it to the four elastic liquid bags 24 through the hose 21 to complete the filling of the liquid bags; when the insulated delivery pump 33 rotates in the reverse direction, it draws the coolant from the four elastic liquid bags 24 back to the storage tank 34 through the hose 21 and the four-way diverter valve 22 to realize the recovery of coolant.

[0052] The threaded rod 10 is fixedly connected to the bottom end of the lower round seat 26. The bottom end of the threaded rod 10 extends out of the high-voltage power supply box 1, and a hexagonal handle 9 is connected to the bottom of the extended end. The top end of the lower round seat 26 is fixedly connected to the threaded end 27. The bottom end of the upper round seat 23 has a threaded opening, and the threaded end 27 is threaded into the threaded opening. The lower round seat 26 and the upper round seat 23 have a receiving groove for receiving the elastic liquid bag 24 on opposite sides. A flexible sealing barrier (silicone material) is added to the inner wall of the receiving groove. After the elastic liquid bag 24 is placed in the receiving groove, the barrier fits tightly against the outer wall of the elastic liquid bag 24, thereby fixing and limiting the elastic liquid bag 24 and preventing the elastic liquid bag 24 from shifting or bulging out of the receiving groove when it is filled or vibrating.

[0053] The hexagonal handle 9 allows the operator to rotate the threaded rod 10 to adjust the height of the liquid bag mounting base. The operation is convenient. The size of the receiving groove is adapted to the elastic liquid bag 24 and is used to install and position the elastic liquid bag 24, providing a stable installation space for the liquid bag.

[0054] Dimension markings are provided along the length of the outer side of the threaded rod 10. The dimension markings are drawn with a wear-resistant and corrosion-resistant coating and have clear height scales. The scales of the four threaded rods 10 are completely consistent and synchronously calibrated. Operators can use the dimension markings to precisely adjust the lifting height of the liquid bag mounting base to ensure that the support height of the four elastic liquid bags 24 is consistent.

[0055] The top of the elastic liquid bag 24 is connected to an exhaust valve 39, and the inner cavity of the upper round seat 23 has a groove for embedding the exhaust valve 39. The exhaust valve 39 has a hydrophobic and breathable membrane inside. A pull rope 40 is provided between the bottom and top of the elastic liquid bag 24.

[0056] The groove is sized to match the exhaust valve 39, used to fix and limit the exhaust valve 39, preventing it from being squeezed or damaged by collision. It also ensures that the exhaust valve 39 is installed flat, allowing personnel to manually open it without affecting the fit and positioning of the upper round seat 23 and the lower round seat 26. This completely solves the problem of the original exhaust port being easily squeezed. The hydrophobic and breathable membrane only allows air to pass through, effectively blocking coolant penetration and achieving automatic exhaust without liquid discharge. The pull rope 40 is made of high-strength, corrosion-resistant, insulating, and flexible material. Its two ends are fixedly connected to the bottom and top of the elastic liquid bag 24, respectively, to limit the maximum expansion deformation of the elastic liquid bag 24, preventing the liquid bag from over-expanding and causing damage. It also enhances the structural stability of the liquid bag itself, preventing irregular deformation when the liquid bag is full, and ensuring uniform support of the drawer-type circuit components.

[0057] A solenoid valve 25 is installed at the connection between the lower circular seat 26 and the hose 21. The lower circular seat 26 has a connection port for the hose 21 to pass through. The elastic liquid bag 24 is provided with a liquid interface, and a miniature pressure sensor is installed at the liquid interface. The solenoid valve 25 is an explosion-proof miniature solenoid valve with good insulation performance, suitable for high pressure and high-risk environments. It can control the opening and closing of the hose 21, and facilitates the individual control of the coolant delivery and recovery of each elastic liquid bag 24. The miniature pressure sensor is used to monitor the coolant pressure in the elastic liquid bag 24 in real time, so that the operator can understand the operating status of the liquid bag through the display panel 8. When the pressure is abnormal (too high or too low), it can be dealt with in time to avoid damage to the liquid bag or imbalance of the support.

[0058] Two reinforcing plates 12 are arranged along the length of the circuit board 19. The two reinforcing plates 12 are fixedly connected between the first end plate 4 and the second end plate 11. They are made of high-strength insulating material and are used to improve the structural strength of the drawer-type circuit assembly and prevent the circuit board 19 from deforming due to vibration and compression.

[0059] Multiple pressure-reducing components are fixedly connected to the top of the high-voltage power supply box 1. The pressure-reducing components include a top plate 30, which is fixedly connected to the top of the high-voltage power supply box 1. A spring-damped telescopic rod 31 is fixedly connected to the bottom of the top plate 30. A fixed seat 32 is fixedly connected to the bottom of the spring-damped telescopic rod 31. A roller 28 is rotatably connected to the bottom of the fixed seat 32. The tops of the two reinforcing plates 12 are provided with movable limiting grooves 29 along the length direction. The roller 28 is movably positioned in the corresponding movable limiting grooves 29.

[0060] The spring-damped telescopic rod 31 has good elasticity and damping performance, which can achieve flexible downward pressure, ensuring the stability of the limit without affecting the vibration reduction effect of the elastic liquid bag 24. When the drawer-type circuit assembly is inserted or removed, the roller 28 rolls in the moving limit groove 29 to reduce the insertion and removal resistance and facilitate operation. At the same time, the elastic force of the spring-damped telescopic rod 31 acts on the reinforcing plate 12 through the roller 28 to flexibly press down on the drawer-type circuit assembly, achieving double vibration reduction protection and further improving the vibration reduction effect.

[0061] The top and sides of the high-voltage power supply box 1 are equipped with filter vent plates 2. The filter vent plate 2 at the top is provided with an installation port 3. The filter vent plate 2 adopts a porous structure, which has good air permeability and can realize the air circulation between the inside of the box and the outside, assisting in heat dissipation. At the same time, the integrated filter can filter external dust and impurities, preventing dust from entering the box and contaminating the circuit components and circulation components.

[0062] Because the lower round seat 26 and the upper round seat 23 are threaded together, they form a sealed containment space. If the elastic liquid bag 24 leaks, the leaked coolant will be confined within the containment space and will not overflow into the high-voltage power supply box 1, thus avoiding contact with components such as the circuit board 19 and the wiring terminal 35, which could lead to short circuits or leakage.

[0063] For safety reasons, since the lower round seat 26 and the upper round seat 23 are threaded together, the elastic liquid bag 24 will not overflow if leakage occurs. It should be noted that an annular guide groove 38 can be recessed downward at the bottom of the receiving tank. Two insulating leakage detection electrodes are installed inside the annular guide groove 38 to detect whether liquid is leaking.

[0064] Specifically, a dedicated controller is added (integrated on the circuit board 19 of the drawer-type circuit assembly, electrically connected to the first power module 18 and the second power module 37, and provided with stable power by the power modules). The two insulated leakage detection electrodes, the miniature pressure sensor, and the solenoid valve 25 are all connected to the controller by insulated wires. The display panel 8 is also electrically connected to the controller, forming a complete closed loop of "detection-control-display". The two insulated leakage detection electrodes in each annular guide groove 38 are connected to the signal input terminal of the controller through two independent insulated wires. When the electrodes detect leakage (the coolant contacts the two electrodes and conducts), they generate an electrical signal and transmit it to the controller, which then identifies and processes the signal.

[0065] Each elastic liquid bag 24 has a miniature pressure sensor at its liquid inlet connected to the controller's signal input terminal via an insulated wire. The sensor collects the pressure data of the coolant inside the liquid bag in real time and continuously transmits the pressure electrical signal to the controller, which receives and processes the pressure parameters in real time. The four solenoid valves 25 on the lower circular seats 26 are all connected to the controller's signal output terminal via insulated wires. Based on the received leakage signal and pressure signal, the controller outputs a control signal to the corresponding solenoid valve 25 to control the opening and closing of the solenoid valve 25 (for example, if a liquid bag has abnormal pressure or leakage, the controller outputs a signal to close the corresponding solenoid valve 25, cutting off the coolant passage of that liquid bag).

[0066] Meanwhile, the controller can receive manual control commands issued by the operator through the display panel 8 to realize the manual on / off adjustment of the solenoid valve 25. The display panel 8 is connected to the signal output terminal of the controller through an insulated wire. The controller converts the processed leakage warning signal, real-time pressure data, and the working status (on / off) of the solenoid valve 25 into visual signals and transmits them to the display panel 8, which displays them accurately, making it convenient for the operator to monitor and handle abnormalities in real time.
