Abstract
The utility model discloses a flat-coil and copper-sheet transformer, comprising a linear and cake-shaped primary side, a secondary side and a magnetic core, wherein the linear and cake-shaped primary side is formed by winding three layers of insulated wires; the secondary side and the magnetic core are formed by copper sheets; the primary side and the secondary side are assembled on a central pillar of the magnetic core and are exposed in the air; and the heat generated by windings is radiated by the air. The secondary side can bear large current by the copper sheets so as to effectively reduce copper loss and conduct heat as a radiator. Meanwhile, when the current of the secondary side needs to increase, the amount of the copper sheets can be easily adjusted to increase the interfacial area of the copper sheets without affecting the whole production difficulty.
Description
Technical field
The utility model belongs to the electrotechnical elements technical field, relates to a kind of flatwise coil-copper sheet formula transformer.
Background technology
In the high-power big electric current product of exploitation, require more and more higher power density, just must under identical volume, constantly improve power.But the lifting of power will make product temperature raise, product heat radiation difficulty, thus need higher insulation system.Existing transformer, former limit and secondary all are positioned in the cabinet, are difficult to satisfy this requirement.
The utility model content
Technical problem to be solved in the utility model provides a kind of flatwise coil-copper sheet formula transformer, can carry big electric current, and technique for coiling is simple, has good performance of heat dissipation.
The technical solution of utility model is as follows:
A kind of flatwise coil-copper sheet formula transformer comprises the former limit that turns to the line pie with three layer insulation wire, the secondary and the magnetic core that adopt copper sheet to make, and former limit and secondary are assemblied on the magnetic core center pillar; The line cake on former limit adopts four adhesive tapes to fix; Former limit and secondary all are exposed in the air, and heat eliminating medium is an air; Be placed with dielectric film between the copper sheet of secondary.
Beneficial effect:
The utility model, former limit and secondary all expose in air, and the heat that winding self produces distributes by air.Secondary uses copper sheet, and the energy bearing great current can effectively reduce copper loss, also can be used as radiator heat conduction.When secondary current need increase, can regulate copper sheet quantity easily increased its interfacial area simultaneously, and did not influence whole production difficulty.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the front view of flatwise coil-copper sheet formula transformer;
Fig. 2 is the right view of flatwise coil-copper sheet formula transformer;
Fig. 3 is the bottom view of flatwise coil-copper sheet formula transformer;
Fig. 4 is the internal structure explosive view of flatwise coil-copper sheet formula transformer.
Among the figure, 1 for containing the shell of magnetic core, and 2 is the line cake, and 3 is copper sheet, and 4 is dielectric film, and 5 is epoxy plate.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
At first use independent tool coiling line cake 2, use 4 adhesive tapes that the line cake is fixed, and processing copper sheet 3, the copper sheet shape designs according to the actual requirements, according to product practical structures design dielectric film 4, guarantee that this film can isolate adjacent two materials, and epoxy plate 5. is assembled into all materials on the magnetic core according to flatwise coil-copper sheet formula transformer internal structure explosive view such as Fig. 5 then.
Three layer insulation wire coiling line cake is used on former limit, and secondary adopts copper sheet to do winding, guarantees the safety distance of this product, and magnetic core need be regarded the secondary side as.The all windings of this structure all are exposed in the air, and the secondary copper sheet can play the fin effect to a certain extent, have improved the heat dissipation characteristics of product, effectively reduce product temperature.
Above execution mode can also be made some simple deduction or replace, also can be applicable to the electrotechnical elements that other electrotechnical elements that comprise winding and magnetic core need high-power big electric current, as inductor etc.
