Description

Heat dissipation type reactor

Technical field

The present invention relates to reactor technical field, particularly a kind of heat dissipation type reactor.

Background technology

Traditional reactor comprises iron core and coil, and iron core forms by silicon steel sheet is superimposed, and by winding, the wire outside iron core forms coil.Because the conductive coefficient of silicon steel sheet is about 22.6-40 watt of/meter of Kelvin, belong to the poor material of heat conductivility, so, in the time that reactor is worked, the heat that core interior produces is difficult to distribute to the external world, so that traditional reactor exists the deficiency of temperature rise.In order to suppress the technical problem of temperature rise, at present mainly by preventing that in conjunction with oil immersion, the mode such as air-cooled temperature rise is too high, but increase reactor volume, and increase its manufacturing cost, and technique operability is low, resultant effect is bad.

In addition, between coil and iron core, gap is very little, and the heat that coil and iron core gap place produce is also difficult to distribute to the external world, affects equally the useful life of reactor.

Summary of the invention

The object of the present invention is to provide a kind of simple and reasonable for structurely, volume is little, good heat dissipation effect, long service life, heat dissipation type reactor that cost is low, to overcome the deficiencies in the prior art.

The object of the present invention is achieved like this:

A kind of heat dissipation type reactor, comprises iron core and coil, and by winding, the wire outside iron core forms coil, it is characterized in that: described iron core is formed by stacking jointly by silicon steel sheet and non magnetic conducting strip.

Object of the present invention can also adopt following technical measures to solve:

As a kind of scheme more specifically, described non magnetic conducting strip is aluminium flake, or described non magnetic conducting strip is aluminum alloy sheet.

Described non magnetic conducting strip clamps and is arranged between the silicon steel sheet and silicon steel sheet of iron core.

Described non magnetic conducting strip is provided with one.Or described non magnetic conducting strip is provided with more than two, each non magnetic conducting strip is disposed in iron core.

As another kind of scheme more specifically, described non magnetic conducting strip is arranged on the silicon steel sheet outside at iron core two ends.

Between described coil and iron core, space is filled with heat filling.

As another scheme more specifically, described non magnetic conducting strip extends outside iron core.

Described non magnetic conducting strip is positioned at and on the one end outside iron core, is also provided with radiator.

Beneficial effect of the present invention is as follows:

(1) iron core of this kind of heat dissipation type reactor includes the non magnetic conducting strip that conductive coefficient is higher, and the heat that core of reactor can be produced take rapidly product outside to, and to overcome the problem of temperature rise, and simple in structure, easy realization, cost are low;

(2) non magnetic conducting strip can be arranged between the silicon steel sheet of iron core, the inner core of reactor heat producing can be taken rapidly to product outside;

(3) non magnetic conducting strip can be arranged on the two ends of iron core, and, in reactor copper busbar and iron core gap and coil and iron core gap place fill heat filling, the heat of reactor winding and copper bar inner side is drawn out to rapidly on the non magnetic conducting strip of core ends by heat filling, has solved the problem that between iron core and coil and copper bar, gap location heat is difficult to leave;

(4) non magnetic conducting strip outer end is connected with radiator, thereby make the heat fast transfer of interiors of products to product outside, make the radiating effect of reactor entirety better, reach the object of the temperature rise that reduces reactor, what iron core just can do like this is relatively a little bit smaller, and the dwindling of core volume, realize reactor miniaturization, reduce again the cost of reactor simultaneously;

(5) non magnetic conducting strip is selected the aluminium that conductive coefficient is higher (fine aluminium) sheet or aluminum alloy sheet, and aluminium class material is again nonmagnetic substance simultaneously, can not produce how many impacts to the major parameter such as inductance value, loss of reactor self;

(6) this kind of heat dissipation type reactor can be widely used in the industries such as Aero-Space, photovoltaic, wind power generation, electric reactive compensating, metal smelt, mine, frequency converter.

Embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

The first embodiment, shown in Figure 1, a kind of heat dissipation type reactor, comprises iron core 2 and coil 1, and by winding, the wire outside iron core 2 is formed coil 1, and described iron core 2 is formed by stacking jointly by silicon steel sheet 21 and non magnetic conducting strip 22.

Described non magnetic conducting strip 22 clamps and is arranged between the silicon steel sheet 21 and silicon steel sheet 21 of iron core 2.

Described non magnetic conducting strip 22 is provided with more than two, and each non magnetic conducting strip 22 is disposed in iron core 2.Certainly, described non magnetic conducting strip 22 also can only arrange one, not shown.

Described non magnetic conducting strip 22 can be aluminium (fine aluminium) sheet, and the conductive coefficient of fine aluminium is about 237 watts of/meter of Kelvins; Non magnetic conducting strip 22 can be also aluminum alloy sheet, and wherein, the conductive coefficient of aluminium alloy 6063 is about 201 watts of/meter of Kelvins, and the conductive coefficient of aluminium alloy 1070 is about 226 watts of/meter of Kelvins.

The second embodiment, is with the difference of the first embodiment: shown in Figure 2, described non magnetic conducting strip 22 extends outside iron core 2 and joins with radiator 3.

The 3rd embodiment, shown in Figure 3, a kind of heat dissipation type reactor, comprises iron core 2 and coil 1, and by winding, the wire outside iron core 2 is formed coil 1, and described iron core 2 is formed by stacking jointly by silicon steel sheet 21 and non magnetic conducting strip 22.
