Embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of multi-coil homogeneous heating electromagnetic wire coil, by drum base 1 and several small coils 2 that are uniformly distributed on the drum base, formed, small coil 2 is comprised of magnetic core 3, bobbin 4 and coil 5, coil 5 is arranged on bobbin 4, between coil and coil, by an enamelled wire coiling, form or each coil respectively coiling by spot welding, coil is connected with the enamelled wire between coil again.Adopt a plurality of small coil combining forms, small coil is evenly distributed on the drum base, and the uniform arrangement mode of small coil can effectively be realized the homogeneous heating of square position.
The fixed form of small coil and drum base can be divided into following two kinds:
1. bobbin is fixedly installed on the drum base, and magnetic core is arranged in bobbin, and it is square, circular or semicircle that magnetic core can be set to;
2. magnetic core is fixedly installed on the drum base, and bobbin is socketed on magnetic core, and now, magnetic core can be set to inverted T shape or slab construction; When magnetic core is inverted T shape, be penetrated into coil from bottom in the middle of, add high-intensity magnetic field; When magnetic core is slab construction, magnetic core is fixedly installed on the drum base, and bobbin is arranged on the magnetic core top.
Coil can, for dredging around structure or close around structure, be dredged and can reduce the turn-to-turn short circuit problem between coil around structure; Coil also can, for two-layer or two-layer above structure, meet the requirement of electromagnetic oven power.
Coil is that lamination is dredged when structure, need to arrange insulating barrier between lamination, take double-layer structure as example, be divided into inner coil and outer coil, the distance of the wire diameter in interval between the enamelled wire of inner coil and enamelled wire, the outer coil winding is in the interval of inner coil enamelled wire and enamelled wire.Lamination is dredged can save around structure the disadvantage that space(d) winding need to block the line tooth, can greatly save the winding space of coil.
