Embodiment Construction

[0016] Referring to the accompanying drawings, the structure of the low-voltage, high-current, and high-power inductor is that the magnetic core 4 is installed in the aluminum-based metal radiator component 1, and the aluminum-based metal radiator component 1 is installed in the winding 2 that has been filled with heat-conducting insulating resin. Lead pins 3 are provided on the left and right of the bottom of the winding 1 sealed with thermally conductive insulating resin, and the slightly deformable arc-shaped contact surface inside the aluminum-based metal radiator component 1 is set on the two heat sinks on the top of the aluminum-based metal radiator component. room and inside the central column.

[0017] The structure of the aluminum-based metal radiator component includes a radiator and a heat conduction device, wherein one end of the heat conduction device is connected to the radiator, and the other end goes deep into the magnetic core installation hole, and the inner w...

Abstract

The invention discloses a low-voltage large-current and high-power inductor. A structural magnetic core is installed in an aluminum-based metal radiator component which is installed in a winding, terminal pins are arranged on the left side and the right side of the bottom of the winding, and an arc contact surface capable of slightly deforming inside the aluminum-based metal radiator component is arranged between two cooling fins at the top of the aluminum-based metal radiator component and located inside a center column. The low-voltage large-current and high-power inductor has the advantages that the skin effect is reduced, the occupation height is reduced compared with a strand wire, and the structure is simple; small holes are formed in copper foil at equal intervals, screw rods made of materials not sensitive to filling and sealing of thermal conductive and insulating materials penetrate through the small holes and a glass insulation sheet to be fixed, the copper foil is separated to prevent short-circuiting, and the winding has the minimum thickness; the copper foil is arranged in a die with a diversion trench, the thermal conductive and insulating materials are used for filling and sealing, and the slight vibration and vacuumizing mode can prevent bubbles generated in the filling and sealing process from affecting the insulation effect; the arc contact surface can increase the contact area between a radiator and the magnetic core and improve the thermal conductive capacity.

Description

technical field [0001] The invention relates to a low-voltage, high-current, and high-power inductor and an installation method thereof, belonging to the technical field of low-voltage devices. Background technique [0002] With the rapid development of information technology and microelectronics process technology, the feature size of devices is getting smaller and smaller, and the power supply voltage of integrated circuits is getting lower and lower. The cost of low-voltage devices is lower and the performance is better. Therefore, major semiconductor companies focus on promoting low-voltage integrated circuits such as 3.3V and 2.5V. For example, high-end DSP, PLD / FPGA products have widely used 3.3V and 2.5V. V or even 1.8V, 1.5V power supply. [0003] However, a low-voltage, high-current, and high-power inductor that can meet the above requirements and has the characteristics of energy saving, flatness, good insulation characteristics and temperature characteristics has...
