<p>A static induction apparatus has a coil inductively disposed on an iron core and cooled by a condensible refrigerant, the coil including a plurality of pancake coil sections stacked in axially spaced relationship on one another by having a plurality of spacers having a predetermined common height and radially inserted in predetermined equal angular intervals into a gap formed between each said of adjacent coil sections, and a plurality of guide members radially disposed in spaced relationship on the surface of each coil section to alternate the spacers so that the guide members alternately and radially protrude beyond outer and inner peripheral surfaces of the coil sections to receive and introduce the refrigerant into the mating gaps.</p> |
