[0040] Specifically, by installing the first stepped structure 12 and the second stepped structure 13 at both ends of the skeleton 11, the side of the first stepped structure 12, the skeleton 11, and the side of the second stepped structure 13 form at least a first winding groove 103, a second winding groove 104, and a third winding groove, the first winding layer 21 is arranged in the first winding groove 103, the second winding layer 22 is arranged in the second winding groove 104, and the third winding layer 23 is arranged in the third winding groove; when the width of the first winding groove 103 and the width of the second winding groove 104 are fixed, the number of turns of the first winding layer 21 and the second winding layer 22 can be calculated according to the width of the flat wire 2, for example, the number of turns of the flat wire 2 in the first winding groove 103 and the second winding groove 104 is consistent with the designed number of turns, then the flat wire 2 on the skeleton 11 must be neat and close to the line.
[0041] Moreover, the number of turns of the flat wire 2 in the first winding layer 21 is less than that in the second winding layer 22, the number of turns of the flat wire 2 in the second winding layer 22 is one more than that in the first winding layer 21, so that the flat wire 2 in the first winding layer 21 is arranged staggered with the flat wire 2 in the second winding layer 22, and the center line of the flat wire 2 in the first winding layer 21 is aligned with the adjacent two flat wires 2 in the second winding layer 22, when the coil structure 100 is heated, the flat wire 2 in the first winding layer 21 is arranged staggered with the flat wire 2 in the second winding layer 22, and the center line of the flat wire 2 in the first winding layer 21 is aligned with the adjacent two flat wires 2 in the second winding layer 22, so that the flat wire 2 in the first winding layer 21 is arranged staggered with the flat wire 2 in the second winding layer 22, and the center line of the flat wire 2 in the first winding layer 21 is aligned with the adjacent two flat wires 2 in the second winding layer 22.
