According to a first aspect of the present invention, as shown in fig. 1 to 3, there is provided a coil panel assembly 100 including a support 110, a coil panel 130, and a heat dissipation part 140. The coil disk 130 is disposed on the support 110. The heat dissipation part 140 is disposed on the bracket 110 in a direction from the center of the coil disk 130 to the outer edge of the coil disk 130.

The utility model provides a coil panel subassembly 100 includes support 110, coil panel 130 and heat dissipation portion 140, and support 110 is used for assembling coil panel 130, avoids coil panel 130 directly to paste on other structures of electromagnetic heating subassembly 200 or electromagnetic cooking utensil, prevents in long-term use, and coil panel 130 drops or takes place the position change, coil panel 130 and electromagnetic heating subassembly 200 or electromagnetic cooking utensil's other structure direct contact and the potential safety hazard problem that arouses. The heat dissipation part 140 is disposed on the bracket 110, and heat generated by the coil panel 130 during use can be dissipated through the heat dissipation part 140, thereby preventing the heat of the coil panel 130 from being concentrated inside the bracket 110 and being not dissipated to cause safety problems. The utility model discloses well heat dissipation part 140 sets up on support 110 to can conveniently in time discharge the produced heat of coil panel 130, avoid the heat gathering in support 110. Specifically, the heat dissipation portion 140 is a heat dissipation opening, a heat dissipation grid, or the like.

Among them, the heat dissipation part 140 is disposed on the bracket 110 in a direction from the center of the coil panel 130 to the outer edge of the coil panel 130, that is, the heat dissipation part 140 is disposed on the bracket 110 to extend from the inside to the outside. It is noted that "inner" in the inside-out direction refers to the central region of the coil disk 130, and "outer" refers to the outer edge region of the coil disk 130. The coil disk 130 is formed of a multi-turn coil. The extending direction of the heat dissipation portion 140 intersects with the winding direction of the coil disk 130, so that the overlapping area of the heat dissipation portion 140 and one coil is small. In the winding process of coil panel 130, the heat dissipation part 140 that sets up from inside to outside can prevent that the coil from stretching into in the heat dissipation part 140, do benefit to the coiling of coil, thereby promote coil panel 130's manufacturability, simultaneously, the friction between coil and support 110 among the winding process can also be reduced in setting up of heat dissipation part 140, prevent support 110 scraping coil and make the coil impaired, and then ensure coil panel 130's normal performance, prevent that the insulating layer of coil is impaired and influence the normal performance of coil in the winding process. It is worth mentioning that the coil comprises a lead and an insulating layer arranged on the outer surface of the lead, and the insulating layer can ensure the insulating property of the coil and prevent the potential safety hazard caused by the short circuit of the coil.

It is noted that the bracket 110 may be made of Polybutylene terephthalate (PBT), Polyethylene terephthalate (PET), Acrylonitrile Butadiene Styrene (ABS), Bulk Molding Compound (BMC), or plastic material.

Further, as shown in fig. 4 and 8, a first end of the heat dissipation part 140 is disposed on the bracket 110 corresponding to an inner edge of the coil disk 130, and a second end of the heat dissipation part 140 extends toward an outer edge of the coil disk 130.

In this embodiment, the coil disk 130 is wound inside the support 110, the first end of the heat dissipation part 140 is provided on the support 110 corresponding to the inner edge of the coil disk 130, and the second end of the heat dissipation part 140 extends toward the outer edge of the coil disk 130, so that the extending direction of the heat dissipation part 140 and the winding direction of the coil disk 130 are distributed crosswise, and the maximum heat dissipation effect can be achieved on the basis of ensuring the supporting effect of the support 110 on the coil disk 130 and the structural strength of the support 110. Specifically, when the coil disk 130 is circumferentially wound around the center of the support 110, the heat dissipation part 140 may extend in a radial direction of the support 110. The coil disk 130 is wound around the circumference and the heat dissipation portion 140 extends in the radial direction, thereby forming a cross distribution. When the number of the heat dissipation parts 140 is plural, the plural heat dissipation parts 140 are radially arranged on the support 110.

In this embodiment, the number of the heat dissipation parts 140 is plural, and the plurality of heat dissipation parts 140 are arranged on the support 110 at intervals, so that the maximum heat dissipation effect of the coil disk 130 can be achieved on the basis of ensuring the supporting function of the support 110 for the coil disk 130 and the structural strength of the support 110. When there is no other structural limitation on the support 110, the plurality of heat dissipation portions 140 may be radially arranged on the support 110. If the bracket 110 is provided with another structure, the plurality of heat dissipation portions 140 may be arranged on the bracket 110 at intervals avoiding the other structure, and as long as the extension direction of the heat dissipation portions 140 is arranged to cross the winding direction of the coil disk 130, the maximum heat dissipation effect and the maximum structural strength of the bracket 110 can be ensured.

It should be noted that the plurality of heat dissipation portions 140 and the bracket 110 may be manufactured by an integral molding process and mass-produced, so as to improve the processing efficiency of the product and reduce the processing cost of the product.

Further, the sum of the areas of the plurality of heat dissipation portions 140 is 5.7% or more and 33.4% or less of the area of the bracket 110.

In this embodiment, the area of the plurality of heat dissipation portions 140 refers to a projection area of the plurality of heat dissipation portions 140 on a horizontal plane when the bracket 110 is placed on the horizontal plane, and the area of the bracket 110 refers to a projection area of an outer contour of the bracket 110 on the horizontal plane when the bracket 110 is placed on the horizontal plane. When the sum of the areas of the plurality of heat dissipation portions 140 and the area of the bracket 110 satisfy the above relationship, the maximum heat dissipation effect and the maximum structural strength of the bracket 110 can be ensured. That is, when the sum of the areas of the plurality of heat dissipation parts 140 is less than 5.7% of the area of the bracket 110, the plurality of heat dissipation parts 140 cannot effectively dissipate the heat generated by the coil panel 130 in time, that is, a large amount of heat generated by the coil panel 130 cannot be smoothly dissipated from the heat dissipation parts 140; when the sum of the areas of the plurality of heat dissipation portions 140 is greater than 33.4% of the area of the support 110, the area of the plurality of heat dissipation portions 140 is too large, and although the heat generated by the coil panel 130 can be dissipated in time, the area of the support 110 is small, the structural strength of the support cannot be guaranteed, and reliable support cannot be provided for the coil panel 130.

Further, the bracket 110 includes a first bracket 111 and a second bracket 112, the second bracket 112 and at least a portion of the first bracket 111 form a winding space, a distance between an outer edge of the second bracket 112 and a wall surface of the first bracket 111 facing the second bracket 112 is H, that is, H represents a width of an outermost edge of the winding space, when the first bracket 111 and the second bracket 112 deform, the width of H changes, and the width of H is obtained by a vernier caliper, so as to determine a deformation amount of the bracket 110, and further determine whether the setting of the heat dissipation portion 140 on the bracket 110 meets the heat dissipation requirement of the coil panel 130.

It is shown through a great deal of experimental data that the temperature of the coil in the coil disk 130 can be detected using a heat sensitive thermometer, as shown in fig. 9 and table 1 below. Specifically, the coil temperatures at different positions of the support 110 and the deformation of the support 110 can be collected, and the data at multiple positions are averaged, so that the data error can be reduced, and the data can be closer to an actual value.

				5	27.9	4.1	121

				7	39.1	5.6	120

Note that: s' is the area of the plurality of heat dissipation portions 140, and S is the area of the support 110.

When the ratio of S'/S is more than 5.7% and less than 33.4%, H of the support 110 is less than 4.5mm, the temperature of the coil is lower than 135 ℃, namely, heat generated by the coil panel 130 can be dissipated in time, and meanwhile, the deformation of the support 110 can be ensured not to be overlarge, the support 110 is prevented from losing rigidity, the strength is low, so that the phenomenon of wire overlapping which is possibly caused after the coil enters a winding space is avoided, and the safety problem which is possibly caused by large change of electrical parameters of the coil is avoided. Specifically, the ratio of S'/S may be 6%, 10%, 15%, 20%, 25%, 30%, 33%, etc.
