Abstract

The utility model belongs to a high-frequency transformer for an inversion power supply, which overcomes the defect of high-temperature rise of the existing high-frequency transforme and is composed of magnetic cores of the high-frequency transformer and a coil. Two sides of each of the magnetic cores are respectively provided with a non-magnetic conduction metal fin; the metal fin are E shape, and the outside of the metal fin are provided with a small turning piece. Thus, the thermolysis effect is raised. The utility model has the advantages that structure is simple, the high-frequency transformer for an inversion power supply can reduce the temperature rise of the high-frequency transformer greatly, and the high-frequency transformer can be ensured to be in a good working condition.

Description

The inverter high frequency transformer of low temperature rise
The utility model relates to a kind of inverter high frequency transformer, particularly a kind of inverter high frequency transformer with low temperature rise.
The used main transformer of inverter is a high frequency transformer, because the reverse frequency height, its magnetic core heating is severe, add the heating of great number transformer coil, make the internal temperature rising of whole high frequency transformer very fast, but can't ventilate in the high frequency transformer, it is very slow to dispel the heat, so long-time the use, its magnetic core temperature can very fast rising, but because of the Curie point of magnetic core is low, so cause the phenomenon of magnetic core loss of excitation easily, burn electronic component, make inverter generation catastrophe failure.
It is a kind of simple in structure that the purpose of this utility model is to provide, the inverter high frequency transformer of the low temperature rise of good heat dissipation effect.
The utility model is finished with following mode: a kind of inverter of low temperature rise comprises that with the great number transformer being wound with high-frequency transformer coils on the great number magnetic core of transformer is equipped with metal fin in the both sides of every great number magnetic core of transformer, and the side of fin stretches out magnetic core.Fin is metal sheet " E " font, and its outboard end is slit into fritter changes 90 ° of angles, and fin has more than two.Fin is to be made by non-magnetic conductive metal material.
The inverter high frequency transformer of the low temperature rise of the utility model, between the magnetic core of high frequency transformer, install non-magnetic conductive metal piece as fin owing to adopt, and fin stretches out outside magnetic core, utilize the good thermal conduction characteristic of sheet metal, the transformer internal heat is passed to fast the outside heat radiation of transformer, thereby reduce the temperature rise of high frequency transformer significantly, make the great number transformer be in good working order, and because fin is to adopt non-magnetic conductive metal material to make, so can not form magnetic circuit, the magnetic line of force can not produce eddy current loss all by magnetic core on fin.
Fig. 1 is the utility model outward appearance front view
Fig. 2 is A-A cutaway view of Fig. 1
Fig. 3 is B-B cutaway view of Fig. 1
Below in conjunction with accompanying drawing the utility model is described in further detail:
As Fig. 1, Fig. 2, shown in Figure 3, the inverter high frequency transformer of the low temperature rise of the utility model is to be wound with coil 2 on the magnetic core 3 by high frequency transformer, dual-side at every magnetic core 3 is equipped with the fin 1 that non-magnetic conductive metal piece constitutes, fin 1 is to make " E " font by metal sheet or copper coin, and its outer side edges is slit into fritter changes 90 ° of angles, to strengthen radiating effect, fin 1 is the vertical side at magnetic 3, on, the following insertion, as Fig. 1, shown in Figure 2, fin 1 has more than two, the area of plane of fin 1 is greater than the vertical lateral area of magnetic core, its radiating principle is to utilize the good thermal conduction characteristic of fin 1 metallic plate, the internal heat of high frequency transformer (being coil and magnetic core) is passed to fast the outside heat radiation of high frequency transformer, thereby reduce the temperature rise of great number transformer significantly, make high frequency transformer be in good working order, and because metal fin 1 is to make with non-magnetic conductive metal material, it can not form magnetic circuit, the magnetic line of force can not produce eddy current loss all by magnetic core in metal sheet.
