PROBLEM TO BE SOLVED: To enhance the snow melting capacity of an induction heating type snow-melting system. SOLUTION: An electromagnetic induction device 2 comprises: an induction heating coil 21 for generating a magnetic field; an induction heating oscillator 22 for supplying a high-frequency current to the induction heating coil 21; a circulation pipe 23 in which a cooling medium is circulated and which is piped so as to absorb heat generated from the induction heating coil 21 and the induction heating oscillator 22 with the cooling medium; a radiator 24 for dissipating the heat absorbed with the cooling medium to melt snow accumulated on a road R; a pump 25 for forcibly circulating the cooling medium by the radiator 24 and the circulation pipe 23; and electric power supply means 26 for supplying power to the induction heating oscillator 22 and the pump 25. The electromagnetic induction device 2 is mounted on a traveling body 4 which travels by wheels W on a road, the radiator 24 is arranged more forward than the induction heating coil 21 in the traveling direction and at least the radiator 24 is arranged in front of front wheels WF. A steel net 3 for electromagnetic induction heating by the magnetic field generated by the induction heating coil 21 is embedded in the road R. COPYRIGHT: (C)2013,JPO&INPIT |
