<p>PURPOSE:To efficiently prevent occurrence of covering with snow, by using a heat pipe setting a magnetic unit to be a heat source. CONSTITUTION:One end of a heat pipe 6 is fitted on the outer periphery of a wire 1 with a magnetic unit 7 and a metal fittings 8, to form a heat collecting section 61, and the other end is led onto an arm 2 as a heat dissipation section 62. The heat dissipation section 62 is engaged with an insulator 9 which is separately set on the arm 2. From the magnetic unit 7, heat is generated by eddy current along with electrical conduction to the wire 1, and the heat collecting section 61 of the heat pipe 6 is heated. When a temperature in this case is equal to or more than an atmospheric temperature, then working fluid in the generating section 61 is vaporized, and is turned into vapor phase working fluid, and flow latent heat is discharged to the heat dissipation section 62. As a result, the vapor phase working fluid is condensed and is turned into liquid phase working fluid and is returned to the lower heat collecting section 61, and heat from the magnetic unit 7 is transmitted to the heat dissipation section 62. In this case, if it snows, snow near the heat dissipation section 62 is to be always melted by heat discharged from the heat dissipation section 62.</p> |
