The utility model discloses a flat-wise coil heat dissipation structure which comprises coil windings and heat dissipation elements. The flat-wise coil heat dissipation structure is characterized in that each coil winding is composed of a plurality of turns of coils, the coil windings are arranged to be a plurality of layers in an encircling mode from inside to outside, a heat dissipation element is arranged between every two adjacent layers of coil windings, the heat dissipation elements are made of conductive materials or insulating materials, and the coil windings are made of insulating copper wires or insulating aluminum wires in a coiled mode. The flat-wise coil heat dissipation structure is compact in structure, simple in manufacture, good in heat dissipation performance, and beneficial to the objective that manufacturers of power and electronic products produce transformers, electric reactors and inductance products to meet requirements of final users.
Description
Technical field
The utility model relates to a kind of coil, especially a kind of flat-wise coil radiator structure that is used for transformer, reactor and inductance.
Background technology
Transformer, reactor and inductance extensively apply in electric power and the electron trade, and coil windings is the vitals of these products, and the quality that coil windings is made has material impact for the quality of these products.Winding is divided into flat-wise coil and flat-wise coil by its coiling mode, and wherein flat-wise coil is to be formed by insulated copper wire or insulated aluminum wire pitch of the laps, is generally sandwich construction, then overlaps each other between layer and the layer.Transformer, reactor and inductance in use, the coil heating temperature raises, and is will the accelerating coil insulating material aging as can not carrying out efficiently radiates heat, shortens the useful life of these products.In the prior art, the heat radiation of flat-wise coil is undertaken by coil self usually, the flat-wise coil heat dispersion of this radiator structure is not good, in order to improve heat dispersion, to control or the reduction coil temperature, usual method is to strengthen the sectional area of winding wire, make big by the insulated copper wire or the aluminum steel consumption of its made transformer, reactor and inductance, the production cost height, useful life is short, thereby can not fully satisfy the demand of user to high-quality transformer, reactor and inductance.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of compact conformation, makes simply, saves cost and the good flat-wise coil radiator structure of thermal diffusivity, can reduce production cost of products such as transformer, reactor and inductance, and prolong its useful life.
The technical solution of the utility model is: a kind of flat-wise coil radiator structure, comprise coil windings and heat dissipation element, it is characterized in that: described coil windings is made up of multiturn coil, and coil windings from inside to outside around being several layers, is provided with heat dissipation element between the adjacent two layers coil windings.
Described coil windings is the coil windings that insulated copper wire or insulated aluminum wire constitute.
Described heat dissipation element is an electric conductor.
Described heat dissipation element is an insulator.
Be provided with insulating barrier between described coil windings and the heat dissipation element.
The beneficial effects of the utility model are:
1. very compact by the made transformer of the utility model, reactor and induction structure, make more conveniently, and reduced the consumption of coil method, reduced production cost;
2. the utility model can effectively reduce the temperature that coil is produced in use by the tabular heat dissipation element that is provided with and coil windings is used, and can slow down the aging of insulating material on the coil, the useful life of prolongation transformer, reactor and inductance;
3. the utility model is by insulating barrier is set, and is more high pressure resistant, and wide application, can be used in the multiple electric power and electronic product beyond transformer, reactor and the inductance, thereby better met user's request.
Description of drawings
Fig. 1 is the schematic diagram of flat-wise coil radiator structure described in the utility model.
Among the figure, 1-coil windings, 2-coil, 3-heat dissipation element, 4-transformer framework.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1: as shown in Figure 1, a kind of flat-wise coil radiator structure, be positioned at transformer framework 4 outsides, comprise coil windings 1 and heat dissipation element 3, coil windings 1 is made up of multiturn coil 2, coil windings 1 is from inside to outside around 2 layers, be provided with the heat dissipation element 3 that the cross section takes the shape of the letter U between the adjacent two layers coil windings 1, in the present embodiment, heat dissipation element 3 is made of the Copper Foil of conduction, passes through the polyimide film reinforced insulation between coil 2 and the heat dissipation element 3, stretch out outside the coil windings 1 the Copper Foil both ends or one end, thereby have bigger area of dissipation, the shaped design of heat dissipation element 3 can more effective the heat radiation for to match with transformer framework 4 and coil windings 1.
Embodiment 2: a kind of flat-wise coil radiator structure, and its heat dissipation element 3 is made by the ceramic composite of insulation, directly contact between heat dissipation element 3 and the coil 2, all the other structures are identical with embodiment 1.
By the foregoing description as can be known, the utility model compact conformation is made simply, and thermal diffusivity is good, helps electric power and electronics manufacturer and produces high-quality transformer, reactor and the inductor product that satisfies end user's demand.
That describes in the foregoing description and the specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.
