Description
technical field [0001] The invention relates to induction heating technology, in particular to an induction heating device. Background technique [0002] Taking the electromagnetic water heater as an example, the electromagnetic water heater is a typical induction heating device, which uses high-frequency current to generate an electromagnetic field through the induction coil, and the heating element (for example, most of the heating elements use metal tubes) in the electromagnetic field induces eddy current heating, so that Cold water in contact with the metal pipe is heated. Due to various reasons such as the induction coil itself has a certain resistance, the induction coil will generate heat during the working process. According to the law of energy conservation, if the induction coil heats up more seriously, the heat produced by the induction coil is not utilized for heat exchange and dissipation with the surrounding air, and the efficiency of converting electric energ...
