Description
Technical field
The utility model relates to a kind of electric equipment, specifically a kind of miniaturized transformer.
Background technology
Social miniaturization is now the trend of most of equipment, because miniaturization can reduce the consumption of resource, transformer in our life is heavy greatly, it not the appearance in our ideal, it is too little that the transformer diminished can face again area of dissipation, heat can not shed in time, causes transformer life to shorten.
Utility model content
The purpose of this utility model is to provide a kind of miniaturized transformer, 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 miniaturized transformer, comprise housing, drum fin, magnetic core, low-voltage coil, insulation spacer, high-tension coil, insulating paper, oil-out, cooling device, screen pack and oil-in, described magnetic core inside is provided with drum fin, low-voltage coil is provided with outside magnetic core, insulation spacer is provided with outside low-voltage coil, high-tension coil is provided with outside insulation spacer, high-tension coil surface is provided with two-layer insulating paper, described housing upper right side is provided with the fuel-displaced mouth of pipe, the fuel-displaced mouth of pipe connects cooling device, described housing lower left is provided with oil-in, is provided with filter screen in described oil-in.
As further program of the utility model: described magnetic core is made up of polylith iron block.
As further program of the utility model: the material of described magnetic core is ferrite.
As further program of the utility model: the material of described drum fin is ceramic material.
As further program of the utility model: described insulating paper has two-layer.
As further program of the utility model: the right side of described cooling device is fixed by welding on the left of housing.
Compared with prior art, the beneficial effects of the utility model are: utilize high-tension coil to wrap up low-voltage coil and make miniaturized transformer realize miniaturization, drum fin and insulation spacer is utilized again to increase the heat dispersion of miniaturized coil, and then make up the problem of miniaturized radiator heat-dissipation face reduction, fuel feed hole and oil-out position is utilized to make inside transformer better form convection current, thus raising radiating effect, in addition when installing cooling device, the whole right flank of cooling device is connected with housing as heat-delivery surface, radiating effect is maximized, finally by the maximization that realize transformer miniaturization and radiating effect of local to entirety.
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 miniaturized transformer, comprise housing 1, drum fin 2, magnetic core 3, low-voltage coil 4, insulation spacer 5, high-tension coil 6, insulating paper 7, oil-out 8, cooling device 9, screen pack 10 and oil-in 11, described magnetic core 3 is made up of polylith iron plate, the material of iron block is ferrite, magnetic core 3 inside is provided with drum fin 2, the material of drum fin 2 is ceramic materials, because ceramic material not only insulate but also high temperature resistant, and the market price is also cheap, the drum structure of drum fin 2 makes have oil to enter in magnetic core 3, and then allow heat shed, low-voltage coil 4 is provided with outside magnetic core 3, insulation spacer 5 is provided with outside low-voltage coil 4, insulation spacer 5 inside is provided with porous, be convenient to the flowing of oil, and then reach the object of heat radiation, high-tension coil 6 is provided with outside insulation spacer 5, high-tension coil 6 and low-voltage coil 4 are all made up of enamelled wire, here coil is made to look like a square from the side when enamelled wire is wound around, so both ensure that the miniaturization of coil also makes coil heat-delivery surface maximize, high-tension coil 6 surface is provided with two-layer insulating paper 7, the effect of insulating paper 7 prevents oil and enamelled wire from high temperature reacting, described housing 1 upper right side is provided with the fuel-displaced mouth of pipe 8, the fuel-displaced mouth of pipe 8 connects cooling device 9, the right wall of cooling device 9 is weldingly fixed on the left of housing 1, the right wall of cooling device 9 absorbs the heat on the left of housing 1 as radiating surface, housing 1 lower left is provided with oil-in 11, filter screen 10 is provided with in described oil-in 11, because transformer use for a long time can make interior metal generation loss, and then generation particle, of long duration will blocking pipe, heat transference efficiency is significantly reduced, here being provided with screen pack 10 is exactly in order to the impurity in going out to deoil, described oil-in 11 is located at the lower left of housing 1, oil-out 8 is arranged on housing 1 upper right side, better form convection current to allow, that radiating effect maximizes.
Operation principle of the present utility model is: utilize high-tension coil to wrap up low-voltage coil and make transformer realize miniaturization, drum fin and insulation spacer is utilized again to increase the heat dispersion of miniaturized coil, and then make up the problem of miniaturized radiator heat-dissipation face reduction, fuel feed hole and oil-out position is utilized to make inside transformer better form convection current, thus raising radiating effect, in addition when installing cooling device, the whole right flank of cooling device is connected with housing as heat-delivery surface, radiating effect is maximized, finally by the maximization that realize transformer miniaturization and radiating effect of local to entirety.
