Description

A kind of miniaturization high-power transformer component

Technical field

The utility model relates to transformer technologies, and in particular to a kind of miniaturization high-power transformer component.

Background technique

In the high-power high-currents products such as exploitation Switching Power Supply, it is desirable that higher and higher power density, that is, it is necessary Power is constantly improved under identical volume.But the promotion of power will be so that small product size increase, increased costs；With It is desirable to smaller volume, lower cost is contradictory.Therefore existing transformer device structure, is difficult to meet this requirement.

On November 09th, 2011, Chinese utility model patent Authorization Notice No. CN202034188U are disclosed a kind of flat Coil-copper sheet type transformer, the primary side including turning to line pie with three layer insulation wire, the secondary side being made into using copper sheet and magnetic Core, primary and secondary side are assemblied on magnetic core center pillar, and secondary side uses copper sheet, are placed with insulating film between the copper sheet on secondary side, can be carried High current, can effectively reduce copper loss, and it is thermally conductive also to can be used as radiator.But this transformer is due to distance between the copper sheet on secondary side It is close, when needing to carry bigger electric current, generates heat and be easy heap aggregation, it is of no avail increasing copper sheet quantity.

To solve the above-mentioned problems, we are made that a series of improvement.

Utility model content

The purpose of the utility model is to provide a kind of miniaturization high-power transformer components, to overcome prior art institute Existing disadvantages mentioned above and deficiency.

The technical solution of utility model is as follows:

A kind of miniaturization high-power transformer component, comprising: magnetic core, with a root multi-layer insulated wire successively coiling and at series connection The secondary side of the primary side of N number of ring pie of shape and the N+1 flatwise coil being independently made into using enamel-cover flat type copper wire；N number of ring cake Shape coil and N+1 flatwise coil are superimposed, and are assemblied on magnetic core center pillar；All first extractions of the N+1 flatwise coil End in parallel is a total first exit, and all tail exit parallel connections are a total tail exit；

Above-mentioned N number of ring pie the number of turns is all the same, around to consistent when assembly；Above-mentioned N+1 flatwise coil, each the number of turns Also identical, around to consistent when assembly;

The N is the integer greater than 2.

Further, the ring pie and flatwise coil overlap two-by-two between be placed with insulating film.

The utility model has the beneficial effects that

The primary and secondary side of the utility model all it is exposed in air, winding itself generate heat distributed by air.

The utility model is compared with traditional technology, with multiple flatwise coil pair sides for separating independent coiling, flatwise coil pair Primary side ring pie is accompanied between side, has deliberately pulled open distance between the copper sheet on flatwise coil pair side, while also having pulled open original The distance between side ring pie plays the role of fine security isolation, while being conducive to radiate, and realizes small size dress Match.The utility model flatwise coil consistency is good, does not influence whole production difficulty, and synchronous production may be implemented, and improves work Efficiency reduces production cost.

Appended drawing reference: 1 magnetic core；2 ring pies；3 flatwise coils；4 first exits；5 tail exits.

Specific embodiment

Below in conjunction with specific embodiment, progress explanation is made to the utility model.It should be understood that following embodiment is merely to illustrate The utility model is not for restriction the scope of the utility model.

Embodiment 1

Fig. 1 is the structure chart of the utility model.

As shown in Figure 1, a kind of miniaturization high-power transformer component, comprising: magnetic core 1, with a root multi-layer insulated wire successively Coiling and the flatwise coils 3 being independently made at the primary side of three ring pies 2 of series-like and four use enamel-cover flat type copper wires Secondary side；Three ring pies 2 and four flatwise coils 3 are superimposed, and are assemblied on 1 center pillar of magnetic core；Described four flat All first exits 4 of coil 3 in parallel are a total first exit, and all tail exits 5 in parallel are a total tail exit；

Above three ring 2 the number of turns of pie are all the same, around to consistent when assembly；Aforementioned four flatwise coil 3, each circle Number is also identical, around to consistent when assembly.

Insulating film is placed between the overlapping of the ring pie 2 and flatwise coil 3 two-by-two.
