[0022] The technical schemes in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-5The utility model provides a technical scheme: a novel resonant integrated inductor, including casing 1, base 2 and juxtaposedly arranged first magnetic core 3 and second magnetic core 4 in casing, casing 1 still is provided with the spacer plate 5 for cutting off first magnetic core 3 and second magnetic core 4, be provided with two windings 6 on first magnetic core 3, the both sides of winding 6 are provided with heat conduction sheet 7, the second magnetic core 4 is provided with the radiating pipe 8 around, the radiating pipe 8 and heat conduction sheet 7 all are connected with heat conduction pipe 9, and heat conduction pipe 9 one end is connected on base 2 and penetrates, casing 1 bottom is provided with the radiating groove 10, and winding 6 bottom is provided with pin 11, and pin 11 is connected on base 2 and penetrates, and the inner side wall of casing 1 still is equipped with a plurality of radiating fins 12.

[0024] Specifically, the heat-conducting glue is filled between the radiating pipe 8 and the heat-conducting sheet 7, so that the heat transfer between the radiating pipe 8 and the heat-conducting sheet 7 is more efficient. The spacer plate 5 is also provided with a plurality of ventilation holes 13 to enhance the internal air circulation and further improve the heat dissipation effect.

[0025] Specifically, the heat-conducting sheet 7 is a copper foil, and the heat-conducting pipe 9 is a copper pipe. By setting the heat-conducting pipe 9 as a copper pipe and the heat-conducting sheet 7 as a copper foil, the heat-conducting capacity of the copper foil and the copper pipe is strong, which significantly improves the heat dissipation performance of the entire inductor. The use of the copper foil and the copper pipe also has good mechanical strength and corrosion resistance, thereby ensuring the stable operation of the inductor in harsh environments.

[0026] Specifically, the radiating groove 10 is designed in a trapezoidal cross-section, which increases the heat dissipation area and further improves the heat dissipation efficiency. In addition, the trapezoidal structure of the radiating groove 10 helps to guide the flow of hot air, and the entire radiating groove 10 and the base 2 form an effective hot air circulation path. This design not only improves the heat dissipation efficiency but also reduces the thermal impact on the surrounding environment.

[0027] Further, the winding 6 is made of a high-thermal-conductivity composite material. By using ultra-high molecular weight polyethylene fiber to composite the winding 6, the overall heat-conducting capacity of the winding 6 is enhanced, thereby further improving the heat dissipation performance of the inductor. The ultra-high molecular weight polyethylene fiber can quickly conduct heat from the inside of the winding 6 to the outside, and due to its excellent insulation performance, it can also effectively prevent unnecessary heat loss of the current in the winding 6, thereby improving the overall efficiency and stability of the inductor.

[0028] Further, the first magnetic core 3 and the second magnetic core 4 are both made of nanocrystalline material, by using nanocrystalline material for the first magnetic core 3 and the second magnetic core 4, the nanocrystalline material has high magnetic permeability and high saturation magnetic flux density, and can withstand greater current without saturation. In the microstructure of the nanocrystalline material, the grain size is in the nanometer level, which greatly improves the magnetic properties of the material. Through material testing, the saturation magnetic flux density of the nanocrystalline material is more than 20% higher than that of the traditional ferrite material, and the decline of the inductance value under high current conditions is significantly reduced.

[0029] One specific application example of the embodiment is:

[0030] When the device is in use, first, the inductor is installed on the circuit board, ensuring that the pin 11 is correctly connected to the corresponding pad of the circuit board. The inductor starts to work, and the winding 6 and the magnetic core inside it will generate a magnetic field. Because the winding 6 made of ultra-high molecular weight polyethylene fiber and the nanocrystalline material magnetic core are used, the inductor can maintain a low temperature under high current conditions, thereby avoiding the overheating problem that may occur when the traditional inductor works under high current.

[0031] As the current increases, the heat dissipation system of the inductor also starts to work. The heat pipe 8 transfers heat from the inside of the inductor. Due to the trapezoidal design of the heat sink 10, hot air can be effectively discharged from the heat sink 10, forming a good heat circulation system.
