Description
Technical field
The utility model relates to a kind of electric equipment, specifically a kind of miniature transformer of high efficiency and heat radiation.
Background technology
Transformer has been applied to our life widely and has suffered, but transformer is usually because heat radiation makes inside transformer temperature more and more higher not soon, and then heat exchanger is burnt, high-power transformer can be dispelled the heat by the oil of circulation, and miniature transformer can not.
Utility model content
The purpose of this utility model is the miniature transformer providing a kind of high efficiency and heat radiation, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of miniature transformer of high efficiency and heat radiation, comprise substrate, side plate, heat sink strip, magnetic core, secondary winding, fin, heat-dissipating cover plate, inner coil, outer coil and armature winding, described substrate is positioned at transformer bottom, surface is provided with armature winding and secondary winding, magnetic core is provided with in the middle part of described armature winding and secondary winding, magnetic core inside is provided with heat sink strip, magnetic core surface is provided with inner coil, inner coil appearance is provided with fin, fin appearance is provided with outside layer line circle, fin, outer coil and inner coil constitute armature winding and secondary winding, described substrate two ends are provided with side plate, the upper end of side plate is provided with heat-dissipating cover plate.
As further program of the utility model: the material of described substrate is nylon based.
As further program of the utility model: be provided with two grooves in described substrate.
As further program of the utility model: the material of described fin is aluminium alloy.
As further program of the utility model: described magnetic core is made up of multi-disc magnetic patch.
As further program of the utility model: described side plate is fixed on substrate by hot melt.
Compared with prior art, the beneficial effects of the utility model are: by the layout changing coil on winding, the radiating effect of coil is increased substantially, the radiating effect of magnetic core is increased again by changing core structure, finally by the radiating effect increasing winding coil and magnetic core surface heat transmission speed raising transformer, the utility model is by being significantly increased the radiating rate of the miniature transformer of high efficiency and heat radiation to overall mode by local.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of miniature transformer of high efficiency and heat radiation, comprise substrate 1, side plate 2, heat sink strip 3, magnetic core 4, secondary winding 5, fin 6, heat-dissipating cover plate 7, inner coil 8, outer coil 9 and armature winding 10, described substrate 1 is positioned at bottom the miniature transformer of high efficiency and heat radiation, the material of substrate 1 is nylon based, two grooves in left and right are provided with to place magnetic core 4 in substrate 1, armature winding 10 and secondary winding 5, described go out in armature winding 10 and secondary winding 5 left groove that is placed on substrate 1 respectively and right groove, such one side is that device internal structure is compacter, make the contact area of substrate 1 and magnetic core 4 larger on the other hand, be beneficial to iron core 4 to dispel the heat, inner coil 8 is provided with outside magnetic core 4, fin 6 is provided with outside inner coil 8, the material of fin 6 is aluminium alloys, here aluminium alloy is adopted to be because aluminum alloy materials itself is drawn materials conveniently, there is again good heat conductivility, and the market price of aluminium alloy is more cheap, outer coil 9 is provided with outside fin 6, described outer coil 9, fin 6 and inner coil 8 constitute armature winding 10 and secondary winding 5, here inner coil 8 and outer coil 9 adopt flush system winding, allow coil cover the area of magnetic core 4 maximum as far as possible, such winding reduces the thickness of coil, be conducive to scattering and disappearing of heat, and such winding decreases the use amount of coil, reduce cost, described magnetic core 4 is superimposed by polylith magnetic sheet, the generation of eddy current can be stoped like this, and then reduce the generation of heat, heat sink strip 3 is provided with in the middle part of magnetic core 4, the effect of heat sink strip 3 is that the heat of magnetic core 4 inside is passed to side plate 2, thus reduce the temperature of magnetic core 4, side plate 2 adopts hot-melt adhesive paste fixing on substrate 1, the upper end of side plate 2 is provided with heat-dissipating cover plate 7, heat-dissipating cover plate 7 is by the heat absorption of magnetic core 4 upper surface and then leave, so just make armature winding 10, the heat produced when secondary winding 5 and magnetic core 4 work is omnibearing to leave, thus solve conventional small transformer because of the problem making device damage too slowly of dispelling the heat.
Operation principle of the present utility model is: the utility model adopts the radiating rate being improved transformer by local to overall mode, coil windings adopts flush system winding to reduce the thickness of coil, coil is dispelled the heat quicker, on winding, coil is divided into interior loop and exterior loop, centre is provided with fin, the further like this radiating rate accelerating coil, magnetic core adopts the superposition of polylith magnetic sheet to hinder the generation of eddy current, the generation of heat is decreased while reducing the consumption of the energy, the substrate of bottom of device adopts groove type structure, increase substrate and coil, the contact area of magnetic core, thus raising radiating rate, device upper end is provided with heat-dissipating cover plate, heat-dissipating cover plate covers magnetic core, make on coil, the heat of magnetic core upper end is left.
