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
What the present invention relates to is a kind of low-voltage, high-current high power inductors and installation method thereof, belongs to voltage devices technical field.
Background technology
Along with the high speed development of information technology and microelectronic process engineering, the characteristic size of device is more and more less, and the supply voltage of integrated circuit is also more and more lower.The cost of voltage devices is lower, and performance is more excellent, thus Ge great semiconductor company all using low-voltage integrated circuits such as 3.3V, 2.5V as promotion key, DSP, PLD/FPGA product as high-end extensively adopts 3.3V, 2.5V, and even 1.8V, 1.5V power.
But can meet above-mentioned each demand and have and can carry energy-conservation, flattening, the low-voltage, high-current high power inductors of the feature such as insulation characterisitic and good temp characteristic, not yet has report at present.
Summary of the invention
The present invention propose be a kind of low-voltage, high-current high power inductors, its object is intended to the above-mentioned defect overcome existing for prior art, have can carry energy-conservation, flattening, the feature such as insulation characterisitic and good temp characteristic.
Technical solution of the present invention: low-voltage, high-current high power inductors, it is characterized in that magnetic core is arranged in aluminium based metal radiator component, aluminium based metal radiator component is arranged in the winding of embedding heat conductive insulating resin, left and right bottom the winding of embedding heat conductive insulating resin is provided with terminal pin, described aluminium based metal radiator component inside can slight deformation arc contact surface be located at aluminium based metal radiator component top two fin between and newel inner.
Advantage of the present invention:
1) be less than the Copper Foil of 0.25mm as coiling owing to have employed thickness, greatly reduce skin effect, compare stranded wire and take and highly significantly reduce, structure is simple;
2) on Copper Foil, have the aperture being equidistantly installed with quantity and not waiting, the available screw rod made the insensitive material of heat-conducting insulation material embedding through aperture, then is fixed through glass insulation sheet, and separating Copper Foil prevents short circuit and make winding have minimum thickness;
3) Copper Foil fixed is placed on has in the mould of guiding gutter, use suitable heat-conducting insulation material embedding, the insulation effect that has an impact of bubble in potting process can be avoided by the mode slightly shaken and vacuumize;
4) because magnetic core is that ceramic process is fired and formed, have tolerance and have the problem of newel concentric reducer, this arc contact surface can make the contact area of conductive structure and magnetic core newel increase the raising capacity of heat transmission as much as possible, avoids heat build-up in the inside of inductance.
