Concentric induction heating for dismantlable adhesion method

A dismantlable (=dismantle-able) adhesion method using electromagnetic induction heating (IH) and thermoplastic adhesive has been proposed. The feature of this method is easily able to bond and dismantle in many times. In conventional interior works, a circle type induction coil is applied. But this coil is ineffective for concentric heating and deep distance heating to load metal. So due to effective adhesion depend on induction heating (IH), we carry an experiment on the new concentric coil with ferrite core because it generates many magnetic fluxes to load metal at deep distance. In the study, a single-phase concentric coil using U-shape ferrite core is proposed. Its experiments and analysis for induction heating (IH) and the electric characteristics are discussed in this paper, and the usefulness of proposed coil is proved.
