<P>PROBLEM TO BE SOLVED: To provide a reactor device capable of radiating heat generated from a coil part by using a portion of a reactor coil to be connected to an external device. <P>SOLUTION: A side wall part 321 of a reactor case 32 comprises a radiation surface 21 which comes into contact with a heat radiation member for radiating heat generated from a coil part 151. A first extension part 154 of a reactor coil 15 is arranged closer to the side of the radiation surface 21 than the center of the annular coil part 151. Consequently, when compared with the case in which the first extension part 154 is arranged on the side 180 degrees opposite to the side of the radiation surface 21 with respect to the center of the annular coil part 151, the heat transfer distance from the first extension part 154 to the radiation surface 21 is shortened. Thus, by using the first extension part 154, which is a portion of the reactor coil 15 to be connected to an external device, heat generated from the coil part 151 of the reactor coil 15 can be radiated to the reactor case 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
