Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

as shown in fig. 2 and 3, the coil disk provided by the embodiment of the first aspect of the present invention includes a flat coil 10 and a coil bobbin 20.

Specifically, the flat coil 10 is formed by punching a conductive metal plate and is directly manufactured into a coil, instead of a conventional coil formed by winding a plurality of strands. Because the flat coil 10 is a very good electric using device, the insulating property of the product can be improved, the electric potential safety hazard is prevented, the processes of bunching and winding of multiple strands of wires are omitted, the large-scale industrial automatic production is more favorably realized, and the production cost is effectively saved. The conductive metal plate is typically a copper plate. The width of the turn line of the flat coil 10 is greater than the thickness, the wire coil body 20 is an injection-molded and integrally-molded structure, and comprises two surfaces which are arranged back to back, and the flat coil 10 is positioned between the two surfaces. In the embodiment of the present invention, in order to facilitate heat dissipation of the coil, the first surface 201 and the second surface 202 of the wire coil body 20 do not completely cover the flat coil 10, but only cover a part of the area. The covered areas may or may not coincide, and in this embodiment, the areas covered by the first surface 201 and the second surface 202 coincide.

In one embodiment of the present invention, the area of the flat coil 10 that is covered is at least 40% of the total area of the coil.

Preferably, in some embodiments, the first surface 201 and the second surface 202 are in the form of spaced blades, and this structure makes the heat dissipation of the flat coil 10 uniform.

In an embodiment of the present invention, the wire coil body 20 further includes a plurality of blocking ribs 203 connecting the first surface 201 and the second surface 202 and filling a turn gap of the flat coil 10. If the coil turns have the same pitch, the stop rib 203 is filled in each coil gap to help maintain the consistency of the pitch of the turns, and meanwhile, the overall firmness of the coil panel is improved, and short circuit caused by too small pitch can be prevented.

Generally, in some embodiments, the wire reel body 20 further includes an inner ring portion 204 that wraps the innermost turn of the flat wire coil 10 and an outer ring portion 205 that wraps the outermost turn. The inner ring portion 204 and the outer ring portion 205 are used to connect and support the first surface 201 and the second surface 202, enhance the strength of the coil disc, and protect the coil turns at the innermost and outermost turns. The manufacturing method of the coil panel of the embodiment is as follows:

The method comprises the steps of putting a metal flat coil 10 into a plastic mold for injection molding, cladding and fixing the flat coil 10 through an injection molding process, forming a coil disc, wherein the flat coil 10 is integrated through in-mold injection molding, the molded plastic passes through an inner ring part 204, a blocking rib 203 and an outer ring part 205 which are mutually connected, the firmness of the flat coil 10 is improved, the flat coil 10 is prevented from generating distortion deformation, and the gap of each circle of turns of the coil is ensured to meet the design requirement, the flat coil 10 is manufactured through the injection molding process, the overall strength of the coil disc can be improved, the thickness of the coil disc is reduced, the blocking rib 203 is utilized to achieve the fixing effect, the plastic cladding area is further reduced, and the heat dissipation effect is achieved.

According to the different shapes of the flat coil 10, the coil panel of the present invention can have various shapes such as circular, polygonal, irregular, etc.

the utility model provides an electromagnetic heating equipment, because of being provided with among the above-mentioned arbitrary technical scheme coil panel to have above whole beneficial effect, no longer give unnecessary details.
