Abstract

The utility model relates to a coil radiating structure of an electric reactor. The electric reactor comprises an iron core and a coil. The coil is composed of a lead wire wound on the outer portion of the iron core. The outer sides of the two ends of the iron core are provided with non-magnetism heat conducting pieces. A gap between the coil and the iron core is filled with heat conducting padding. The two ends of the iron core of the electric reactor are provided with the non-magnetism heat conducting pieces high in heat conducting coefficient, a gap between an electric reactor wire connecting copper bar and the iron core and the gap between coil and the iron core are filled with heat conducting padding, heat of the electric reactor coil and the inner side of the copper bar is guided out quickly to the non-magnetism heat conducting pieces at the ends of the iron core quickly through the heat conducting padding, the problem that heat at the gaps between the iron core, the coil and the copper bar cannot be dissipated easily is solved, temperature rising is effectively avoided, accordingly, the iron core can be made relatively small, the size of the iron core is reduced, miniaturization of the electric reactor is achieved, the structure is simple, achieving is easy, and cost is low.

Description

The coil radiator structure of reactor

Technical field

The utility model relates to the coil radiator structure of reactor technical field, particularly a kind of 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, simultaneously, between coil and iron core, gap is very little, so when reactor is worked, the heat that coil and iron core gap place produce is difficult to distribute to the external world, so that traditional reactor exists the deficiency of temperature rise, affect the useful life of reactor.In order to overcome above-mentioned deficiency, at present mainly by preventing that in conjunction with oil immersion, the mode such as air-cooled reactor temperature rise is too high, but increase reactor volume, and increase its manufacturing cost, and technique operability is low, resultant effect is bad.

Utility model content

It is a kind of simple and reasonable for structure that the purpose of this utility model is to provide, and volume is little, the coil radiator structure of coil good heat dissipation effect, long service life, reactor that cost is low, to overcome the deficiencies in the prior art.

The purpose of this utility model is achieved in that

A kind of coil radiator structure of reactor, described reactor comprises iron core and coil, by winding, the wire outside iron core forms coil, it is characterized in that: outside, described iron core two ends is provided with non magnetic conducting strip, and between coil and iron core, space is filled with heat filling.

The purpose of this utility model can also adopt following technical measures to solve:

As scheme more specifically, described iron core forms by silicon steel sheet is superimposed, and non magnetic conducting strip is superimposed on the silicon steel sheet outside at iron core two ends.

Described non magnetic conducting strip is aluminium flake, or described non magnetic conducting strip is aluminum alloy sheet.

As better scheme, 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.

The beneficial effects of the utility model are as follows:

(1) the iron core two ends of this kind of reactor are provided with the non magnetic conducting strip that conductive coefficient is higher, 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, solved the problem that between iron core and coil and copper bar, gap location heat is difficult to leave, effectively overcome the problem of temperature rise, what iron core just can be done like this is relatively a little bit smaller, and the dwindling of core volume, realized reactor miniaturization, and, simple in structure, easily realize, cost is low,

(2) 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, on major parameters such as the inductance value of reactor self, losses, can not produce how many impacts;

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