Description
Technical field
The utility model relates to a kind of low-voltage, high-current high power inductors, belong 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 utility model proposes 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 utility model: 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 utility model:
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.
