発熱する。Generally, this type of coil is used in an arrangement as shown in FIG. 1, and the structure of a conventional coil is as shown in FIG. First, in Fig. 1, (1) is a winding, (2) is an iron core having a convex leg (3), (4N is a gland that applies an alternating current to the winding (1), (5) is the object to be heated, (6) is the magnetic flux.Next, in Fig. 2, (7) is the silicon steel plate, (8) is the water-cooled copper plate, (9
) With these screws (7) to (9), the iron core (
2). In such a configuration, the magnetic flux (
When passing through the #6) and silicon steel plates (7), each ## plate generates eddy loss and hysteresis loss, generating heat.

た。This heat generation is absorbed by the water-cooled copper plate (8), and the humidity of the silicon steel plate (7) is determined when the heat generation and heat absorption are balanced. By the way, in the conventional iron core (2), the water-cooled copper plate (8)
The self-IJ-distance l was uniform in the laminated thickness direction.

事故にまで発展するおそれかあった。However, as can be seen in Figure 1, the flow of magnetic flux (6) is in the ζ1 direction, concentrating at the ends of the convex legs (3, 1) of the iron core (2), and the heat generation of the convex legs (31) is uniform. As a result, the temperature of the silicon steel plate (7) at the end rises to an abnormally high temperature, and in the case of Kino&, there is a risk that the winding will burn out or the silicon copper plate (7) will melt in the bath, which could lead to an accident. There was.
この発明は上記のような従来のものの欠点を除去するた
めになされたもので、水冷銅板(8)の配油間隔を変え

。This invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and attempts to equalize the iron core temperature by changing the oil distribution interval of the water-cooled copper plate (8).

許容範囲内に抑えることができる。That is, FIG. 8 is a sectional view showing one embodiment of the present invention,
Regarding the arrangement interval of the water-cooled copper plates (8), the arrangement interval C at both ends in the stacking direction is set to the arrangement interval C at the center thereof by 1.0 summer thinning. By doing this, it is possible to reduce the temperature of the silicon steel plate at the end and also to suppress leakage magnetic flux within an allowable range.
