For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0017] See also Figures 1 to 3 The box structure for installing a new micro-arc oxidation power supply of an embodiment of the utility model includes a first mounting bracket 1, a second mounting bracket 2 and a main control board 3. The first mounting bracket 1 and the second mounting bracket 2 are closely arranged in the box 7. The first mounting bracket 1 is provided with a power interface row 11, and the second mounting bracket 2 is provided with a voltage box 21. The voltage box 21 is provided with a high-frequency voltage. The voltage box 21 is provided with a water cooling device 4. The high-frequency voltage is connected to the power interface row 11 by wires. The main control board 3 is fixedly arranged on the box 7 and close to the power interface row 11.

[0018] In the above embodiment, the first mounting bracket 1 and the second mounting bracket 2 are placed closely adjacent to each other in the box 7 to make full use of the space. The first mounting bracket 1 is provided with a power interface row 11, which is responsible for receiving external power input. The second mounting bracket 2 carries the voltage box 21, and a high-frequency voltage is installed inside the box 7, which is the core component of power conversion. In order to cope with the high heat generated when the high-frequency voltage is running, the voltage box 21 is integrated with a water cooling device 4, which effectively dissipates heat through circulating water flow, ensures the stable operation of the high-frequency voltage, and reduces the volume occupation. The high-frequency voltage is connected to the power interface row 11 by a short-distance, high-quality wire, which reduces the loss in power transmission. The main control board 3, as the control center of the system, is fixed on one side of the box 7 near the power interface row 11. This layout arrangement is intended to reduce the interference of stray inductance on the drive signal, reduce signal transmission delay, and improve the system response speed. At the same time, the main control board 3 is close to the power input terminal, which is convenient for real-time monitoring of the power status and ensuring stable operation of the system. The design of the transformer box 21 close to the power interface row 11 not only shortens the length of the primary input wire, reduces the line resistance and energy loss, but also significantly reduces the leakage inductance of the high-frequency transformer. The reduction of leakage inductance means the reduction of losses in the energy conversion process, thereby improving the conversion efficiency and energy utilization of the entire power supply system. In summary, the structural design of the box structure 7 for installing the new micro-arc oxidation power supply achieves efficient conversion and stable output of electrical energy by optimizing the layout, integrating an efficient heat dissipation system and shortening the electrical connection path, providing reliable power support for processes such as micro-arc oxidation.

[0019] Please refer to Figures 1 to 3 In another embodiment, it further includes an IGBT5, which is arranged on the first mounting bracket 1 and close to the main control board 3.

[0020] In the above embodiment, IGBT5 is arranged on the first mounting bracket 1 and is located close to the main control board 3. As a power electronic device, IGBT5 is responsible for the rapid conversion and control of electric energy. Its layout design close to the main control board 3 facilitates the main control board 3 to monitor and accurately control IGBT5 in real time, reduces the signal transmission path, reduces the control delay, and improves the response speed and stability of the system. At the same time, this layout also optimizes the space utilization in the power box 7, making the overall structure more compact.

[0021] Please refer to Figures 1 to 3 In another embodiment, at least one of the transformer housings 21 is provided. A plurality of the transformer housings 21 are arranged on the second mounting bracket 2. The water cooling device 4 includes a water circuit, a water pipe 41 and a water inlet 42. The water circuit is built in the transformer housing 21. The water inlet 42 is provided in the transformer housing 21 and communicates with the water circuit. The water pipe 41 is connected to the water inlet 42. The water pipe 41 connects the water inlets 42 on the plurality of the transformer housings 21 in series.

[0022] In the above embodiment, in at least one transformer case 21, these boxes 7 are arranged in order and fixed on the second mounting bracket 2. Each transformer case 21 is integrated with a high-frequency transformer for the conversion, distribution or regulation of electric energy. In order to effectively manage the heat generated by these boxes 7 during operation and prevent performance degradation or equipment damage caused by overheating, a water cooling device 4 is specially designed for heat dissipation. The core components of the water cooling device 4 include a water circuit, a water pipe 41 and a water inlet 42. The water circuit is a cooling channel pre-designed and built into each transformer case 21, and its shape and layout are optimized to ensure that the heat generated inside the case 7 can be covered and absorbed to the greatest extent. The water inlet 42 is arranged on the outer wall of the transformer case 21, as the connection point between the water circuit and the external cooling system, they are directly connected to the inside of the water circuit to ensure that the cooling water can enter and exit smoothly. In order to achieve unified heat dissipation management between multiple transformer cases 21, the water pipe 41 is used to connect the water inlets 42 on each case 7 in series. This design allows cooling water to enter from the water inlet 42 of the first transformer box 21, flow through its internal water path, and then flow to the next box 7 through the water pipe 41, and so on, until it traverses all boxes 7 and completes the cycle. This series connection method not only simplifies the structure of the cooling system, but also improves the cooling efficiency, because the cooling water absorbs and takes away part of the heat when flowing through each box 7. As the cycle proceeds, the water temperature gradually increases, but its ability to carry heat is also fully utilized. In summary, by means of built-in water paths, setting water inlets 42, and using water pipes 41 to connect multiple transformer boxes 21 in series, the water cooling device 4 effectively achieves efficient heat dissipation of the electrical components in the transformer box 21, ensuring the stability and reliability of the equipment under long-term, high-load operation.

[0023] Please refer to Figures 1 to 3 In another embodiment, it also includes a laminated plate 6, which is arranged on one side of the first mounting frame. The laminated plate 6 is provided with a high-frequency clamping capacitor 61, a chopping capacitor 62 and an isolation diode from top to bottom. The high-frequency clamping capacitor 61, the chopping capacitor 62 and the isolation diode are arranged in parallel.

[0024] In the above embodiment, the laminated plate 6 is arranged on one side of the first mounting frame, and its vertical layout is from top to bottom, which is a high-frequency clamping capacitor 61, a chopping capacitor 62 and an isolation diode 63, which are connected in parallel. The high-frequency clamping capacitor 61 is designed to absorb high-frequency voltage fluctuations, protect the chopping capacitor 62 from spike voltage shocks, and ensure that it works in a stable voltage environment. The chopping capacitor 62 is responsible for storing and releasing energy to maintain the stable operation of the circuit. In the design of the laminated plate 6, the laminated busbar reduces the stray inductance through the opening technology. This measure optimizes the current path, reduces the energy loss and electromagnetic interference of the current during the transmission process, and further ensures the reliable operation of the chopping capacitor 62. The opening design also promotes the effective dissipation of heat and prevents performance degradation or damage caused by local overheating. In addition, as a key component in the parallel circuit, the unidirectional conductivity of the isolation diode 63 effectively prevents the current backflow phenomenon that may occur when the power supply is connected in parallel. When multiple power supplies are connected in parallel, if the output voltage of one power supply is higher than the others, the isolation diode 63 will prevent the current from flowing back into the low voltage power supply, especially avoiding the damage of the chopper capacitor 62 due to the reverse current, thereby ensuring the safety and stability of the entire power supply system.
