<p>PURPOSE:To dissipate efficiently the heat generated within a coil, by a method wherein heat pipes each having a heat collecting plate are embedded in the coil and other end thereof is opposed to the fins of a yoke. CONSTITUTION:A plurality of heat collecting plates 8 are made of heat-conductive material, and a plurality of heat pipes 9 with one end embedded are arranged throughout whole circumference of the heat collecting plates 8. The heat pipes 9 together with the heat collecting tubes 8 are inserted in a coil 4 and other end of the heat pipe 9 at upper side is inserted in a hole of a yoke thereby the heat pipe 9 is opposed to the yoke. Thus the heat generated within the coil is transmitted to part of the heat collecting plate 8 and transferred rapidly to the yoke 1 by means of action of the heat pipe 9 and dissipated through the surface of the yoke and a fin 1 into the atmosphere. In this constitution, the heat generated within the coil can be dissipated efficiently.</p> |
