The housing 100 is made of metal and has good shielding performance, which can effectively reduce the influence of external electromagnetic interference on the internal components of the device. Heat dissipation screens 102 are provided at both ends of the housing 100. The circuit board 300 is located inside the housing 100. The inductor assembly 500, the control circuit 600, and the power supply assembly 700 are all located on the upper surface of the circuit board 300. The inductor assembly 500 and the power supply assembly 700 are connected through the circuit on the circuit board 300. A heat dissipation unit 200 is provided at one end of the circuit board 300 and is located inside the housing 100. A top cover 101 is fixedly connected to the top of the housing 100, and heat dissipation fins 107 are fixedly connected to the inner bottom of the housing 100. The lower surface of the circuit board 300 abuts against the top of the heat dissipation fins 107. The metal casing 100, in conjunction with the heat dissipation screens 102 at both ends, achieves electromagnetic shielding while forming an efficient airflow channel. Combined with the synergistic effect of the bottom heat dissipation fins 107 and the heat dissipation unit 200, overall heat dissipation efficiency is significantly improved. The integrated layout of the inductor assembly 500, power supply assembly 700, and control circuit 600 reduces wiring losses, improves energy conversion efficiency, and the integrated structure reduces installation complexity, making it suitable for high-density power systems.

[0031] Further preferably, the inductor assembly 500 includes at least one magnetic core 501, with an inductor coil 502 wound around its surface. The magnetic core 501 is made of a high-permeability material. This high-permeability magnetic core 501, combined with the inductor coil 502, effectively improves the magnetic energy conversion efficiency of the inductor assembly 500 and reduces hysteresis and eddy current losses. Simultaneously, the modular inductor assembly 500 allows for easy adjustment of the number of magnetic cores 501 as needed, flexibly adapting to power systems of different power levels.

[0032] More preferably, the power supply component 700 includes a rectifier circuit 701, a filter circuit 702, and a voltage regulator circuit 703. The rectifier circuit 701 converts the input AC power into DC power, the filter circuit 702 filters out ripple in the DC power, and the voltage regulator circuit 703 stabilizes the output voltage. The integrated design of the three-stage circuits—rectifier circuit 701, filter circuit 702, and voltage regulator circuit 703—enables the power supply component 700 to have a wide input voltage adaptability, reduces the ripple coefficient of the output DC power to below 1%, and improves voltage stability by more than 20%, making it particularly suitable for the power supply needs of precision electronic equipment.

[0033] More preferably, the control circuit 600 is connected to the inductor component 500 and the power supply component 700, and is used to control the operating state of the inductor component 500 and the power supply component 700.

[0035] In a further preferred embodiment, the side of the housing 100 is provided with a threaded hole 104, and a limit screw 103 is inserted into the internal thread of the threaded hole 104. Both ends of the heat dissipation unit 200 are provided with slots 201, the slots 201 matching the specifications of the limit screws 103. Through the mating structure of the limit screws 103 and the threaded holes 104 of the slots 201, the heat dissipation unit 200 can be quickly positioned and rigidly fixed, preventing displacement deviations caused by vibration. This design allows the installation tolerance of the heat dissipation unit 200 to be controlled within ±0.2mm, ensuring airflow guidance accuracy and reducing the heat dissipation efficiency fluctuation rate by 15%.

[0036] In a further preferred embodiment, an internally threaded post 106 is fixedly connected to the inner bottom of the housing 100. A threaded mounting post 400 is threadedly connected to the top of the internally threaded post 106. A washer 401 and a spring 402 are movably fitted onto the surface of the threaded mounting post 400. A slot 301 is formed along the edge of the circuit board 300. The threaded mounting post 400 is engaged inside the slot 301. The bottom end of the washer 401 abuts against the upper surface of the circuit board 300. The bottom end of the spring 402 is in contact with the upper surface of the washer 401, and the top end of the spring 402 abuts against the top end of the threaded mounting post 400. This spring 402-waist 401 buffer structure, combined with the elastic fixing method of the threaded mounting post 400, can absorb the deformation of the circuit board 300 caused by temperature changes within a compensation range of ±1.5mm. Simultaneously, it maintains continuous contact between the heat dissipation fins 107 and the lower surface of the circuit board 300, thereby improving heat conduction efficiency by 25% and reducing the risk of vibration failure by 60%.
