Description
Technical field
The utility model relates to a kind of coil, especially a kind of upright coiling 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 its neutral coiling is formed by insulated copper wire or insulated aluminum wire pitch of the laps, is generally the spirality single layer structure.Transformer, reactor and inductance in use, the temperature height of coil, will the accelerating coil insulating material aging as lacking the good heat radiating structure, shorten useful life of these products.In the prior art, the heat radiation of upright coiling is undertaken by coil self usually, the upright coiling heat dispersion of this radiator structure is not good, in order to improve heat dispersion, control or reduction coil temperature, usual method is to strengthen the sectional area of winding wire, feasible big by the insulated copper wire or the aluminum steel consumption of its made transformer, reactor and inductance, the production cost height, volume is big, 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 provide a kind of compact conformation, easy to make, save cost and the upright efficiently coiling radiator structure of heat radiation, the insulated copper wire or the aluminum steel consumption of transformer, reactor and inductance are reduced, volume is little, production cost is low, heat radiation is strengthened, and coil temperature rise is low, longer service life.
The technical solution of the utility model is: a kind of upright coiling radiator structure, comprise coil windings and radiating subassembly, it is characterized in that: described coil windings twist, be provided with radiating subassembly in the coil windings, coil windings is made up of multiturn coil, radiating subassembly is made up of a plurality of heat dissipation elements, and heat dissipation element is between adjacent windings.
Described coil windings is the coil windings that insulated copper wire or insulated aluminum wire constitute.
The cross section of described coil windings is circle or rectangle.
Described heat dissipation element is an electric conductor.
Described heat dissipation element is an insulator.
Be provided with insulating barrier between described heat dissipation element and the coil.
The beneficial effects of the utility model are:
1. the utlity model has compact conformation and advantage easy to make, reduced the consumption of coil method, feasible little by its made transformer, reactor and inductance volume, production cost is low;
2. the utility model is by being provided with the thermal component of helical structure, and this radiating subassembly cross section is greater than coil section, and area of dissipation is big, can reduce winding temperature rise, and the aging phenomenon that reduces the winding insulation material is to the transformer adverse effect in useful life;
3. the utility model makes coil windings more high pressure resistant by insulating barrier is set, and wide application, can be used in transformer, reactor and the inductance multiple electric power and electronic product in addition, thereby has better met user's request.
Description of drawings
Fig. 1 is the schematic diagram of upright coiling radiator structure described in the utility model.
Among the figure, 1-coil windings, 2-coil, 3-radiating subassembly, 4-heat dissipation element.
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 upright coiling radiator structure, comprise coil windings 1 and radiating subassembly 3, coil windings 1 is made of insulated copper wire, coil windings 1 twist, the cross section of spiral is circular, be provided with radiating subassembly 3 in the coil windings 1, coil windings 1 is made up of multiturn coil 2, radiating subassembly 3 twist, radiating subassembly 3 is made up of a plurality of heat dissipation elements of being made by ceramic composite 4, heat dissipation element 4 is between adjacent windings 2, and the area of heat dissipation element 4 cross sections is bigger than the area of coil 2 cross sections, and the shaped design of radiating subassembly 3 matches with coil windings 1, thereby obtains good performance of heat dissipation.
Embodiment 2: a kind of upright coiling radiator structure, its heat dissipation element 4 is made by the Copper Foil of conduction, pass through the polyimide film reinforced insulation between heat dissipation element 4 and the coil 2, all the other structures are identical with embodiment 1, polyimide film in the present embodiment constitutes insulating barrier, make can better be insulated between coil 2 and the heat dissipation element 4, and more high pressure resistant.
By the foregoing description as can be known, the utility model compact conformation, easy to make, heat radiation is efficient, helps high-quality transformer, reactor and inductor product that electric power and electronics manufacturer are produced low-cost and high life.
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.
