Description

Technical Field

[0001] This utility model relates to the field of inductor technology, and in particular to a power regulating inductor. Background Technology

[0002] In existing technologies, inductors with magnetic cores are commonly used. Under high-frequency and high-current operating conditions, the magnetic core material will generate significant eddy current losses and hysteresis losses. Therefore, the magnetic core is very easy to reach magnetic saturation, which will generate a lot of heat and cause the core temperature to rise too high, seriously affecting the current handling capacity of the inductor. Currently, the market still needs a simple and reliable inductor that solves the problems of heat dissipation and easy saturation of inductors, and does not cause the inductor temperature to rise too high even when high-frequency and high-voltage currents pass through it. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a power regulating inductor that can prevent the inductor temperature from rising too high, ensure fast heat dissipation, and prevent saturation, thereby overcoming the shortcomings of the prior art.

[0005] A power regulating inductor includes a hollow frame, an inductor coil, a fan, and a circuit board. The hollow frame is a hollow cylindrical structure with a winding groove on its outer peripheral wall and two mounting bases on each side.

The inductor coil is wound inside the winding groove, and its two ends are connected to the pins by soldering. The inductor is soldered to the circuit board via the pins. The fan is located on the side of the inductor.

[0006] The hollow frame is made of insulating material. The winding slots are evenly spaced on the outer wall of the hollow frame. Adjacent turns of inductor coils are separated by the slot walls and connected by a wire passage.

[0007] The inductor coil is made of a conductor with good conductivity, including but not limited to copper wire, aluminum wire and silver wire.

[0008] The bottom of the mounting base is provided with a boss, on which the end of the inductor coil is placed and the pin is isolated from the adjacent turn of the inductor coil.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] See Figure 1 As shown, the device includes a hollow frame 2, an inductor coil, a fan 8, and a circuit board 9. The hollow frame 8 is a hollow cylindrical structure with a winding groove 3 on its outer peripheral wall and two fixing seats 5 on each side. The winding groove 3 has a wire passage 4 that allows the inductor coil to pass through. The fixing seats 5 have pins 5. The inductor coil is wound inside the winding groove 3, and its two ends are connected to the pins 6 by soldering. The inductor 1 is soldered to the circuit board 9 via the pins 6. The fan 8 is located to the side of the inductor 1.

[0018] The hollow frame 2 is made of insulating material. The winding grooves 3 are evenly distributed on the outer peripheral wall of the hollow frame 2. Adjacent turns of inductor coils are separated by the groove wall of the winding groove 3 and connected by the wire passage 4.

[0019] The inductor coil is made of a conductor with good conductivity, including but not limited to copper wire, aluminum wire and silver wire.

[0020] The bottom of the mounting base 5 is provided with a boss 7, on which the end of the inductor coil is placed and the pin 6 is isolated from the adjacent turn of the inductor coil.

[0021] The working principle of this utility model:

[0022] Inductor winding: The inductor uses copper wire. The first end of the copper wire is first soldered to the pin 6 of the mounting base 5, and then passes through the wire guide 4 into the winding slot 3 to begin spiral winding. After each turn is completed, the copper wire transitions through the adjacent wire guide 4 to the next winding slot 3, forming a uniformly spaced three-dimensional spiral structure. The last copper wire is led out through the last wire guide 4 and soldered to the corresponding pin 6.

[0023] Air cooling device: The fan 8 is located on the side of the inductor 1 and dissipates heat from the inductor 1 through air cooling. Due to the hollow frame 2 structure of the inductor 1, the air blown by the fan 8 acts on the inner and outer dual circulation heat dissipation channels of the inductor 1. The external airflow flows along the winding groove 3 on the outer peripheral wall of the hollow frame 2, directly dissipating heat from the surface of the copper wire, while the internal airflow dissipates heat through the hollow cavity in the frame, effectively improving the heat dissipation efficiency.

[0024] The design of inductor 1 without a magnetic core, with copper wire directly wound on the hollow frame 2, eliminates magnetic core loss. Even with high-frequency, high-voltage current, the temperature of inductor 1 will not rise too high, thus achieving high-frequency, high-current power regulation.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
