Description

Electromagnetic Coils and Heating Units

technical field

The utility model relates to the electrical field, in particular to an electromagnetic coil and a heating device.

Background technique

Electromagnetic coils and electromagnetic heating devices equipped with electromagnetic coils are widely used in various occasions that require heating, such as mechanical energy-saving transformation, electric heating plates, etc. The existing electromagnetic coils are shown in Figure 1. The heating device 10 includes a coil. The coil includes two Terminals 11 and 12, and several coils 13, each circle of coils are arranged in the heated body 14 next to each other, the inventor finds in practice: the heating coil of the prior art has only one ring because all the coils 13 are arranged side by side. Shape, the heating place is only in the place where there is a coil, so the heating is too concentrated. For the heating element, the heating place is only localized on a small area of the coil surface, resulting in uneven heating temperature. And the coil itself is unfavorable for heat dissipation.

Utility model content

The utility model provides an electromagnetic heating coil and an electromagnetic heating device which disperse heating positions and are beneficial to be fully and uniformly heated by a heating body. And it is beneficial to the heat dissipation of the coil itself.

In order to achieve the above object, the utility model provides the following technical solutions:

An electromagnetic coil, including a plurality of coils wound with wires, the plurality of coils are divided into several turns, and each turn of the coil includes at least two or more turns of the coils arranged next to each other, and each turn of the coil with a certain distance between them.

According to the above main technical features, each turn of the coil is circular, elliptical or square, and the entire heating coil is planar, arcuate or circular.

According to the above main technical features, the plurality of coils can be arranged in a single or plural layers.

A heating device, comprising a heated body, wherein the above-mentioned heating coil is arranged on the surface or around the heated body.

It can be seen from the above technical solution that the electromagnetic heating coil and the heating device provided by the utility model divide the coil into several coils, and then each coil is arranged on the surface of the heated body or around it at a certain distance, which disperses the heating position. , which is conducive to sufficient and uniform heating of the heated body, and is conducive to the heat dissipation of the coil itself.
