Embodiment Construction

[0038] Hereinafter, embodiments of the thin transformer for high-frequency induction heating according to the present invention will be described in detail with reference to the drawings. In addition, the following description is to facilitate understanding of the description of the embodiment, and should not limit the understanding of the present invention thereby.

[0039] First, the configuration of the thin transformer 1 for high-frequency induction heating according to the embodiment of the present invention will be described. The thin transformer 1 for high-frequency induction heating is a device for outputting a high-frequency current to the induction heating coil 50, and is composed of two primary coils 20 and 30, a secondary coil 40, and the like (details will be described later). Such as figure 1 , 2 As shown, the thin transformer 1 for high-frequency induction heating is horizontally wide and thin, and has a high and deep structure. A thin transformer 1 for high...

Abstract

The invention provides a thin type transformer for high-frequency induction heating, which can shorten the distance between induction heating coils. The thin type transformer (1) for high-frequency induction heating is provided with two primary coils (20 and 30) and a secondary coil (40), wherein the primary coils (20 and 30) and the secondary coil (40) are all volute-shaped or ring-shaped conductors and are on the same plane; the secondary coil (40) is arranged at the inner side of the primary coil (20); and the primary coil (30) is arranged at the inner side of the secondary coil (40).

Description

technical field [0001] The invention relates to a thin transformer for high-frequency induction heating. [0002] The present invention is an apparatus for quenching a crankshaft, which is a component of an internal combustion engine of an automobile. Background technique [0003] In the quenching of an object to be heated by high-frequency induction heating, the object to be heated is arranged to face an induction heating coil (induction heating coil), and a high-frequency current is passed through the induction heating coil. As a result, an induced current is generated on the surface of the object to be heated. The induced current is converted into heat by the resistance of the object to be heated. As a result, the object to be heated generates heat, and the object to be heated is rapidly cooled to be quenched. [0004] Quenching of the object to be heated by high-frequency induction heating can be completed in a short time. Therefore, there is very little oxidation of...
