Claims10
A coil device comprising:
- a coil part having a coil;
- a case accommodating the coil part;
- a coolant accommodated in the case;
- and
- a fluid volume adjusting part for supplying the coolant to the case or discharging the coolant from the case,
- wherein the coil part floats in the coolant within the case, and
- wherein the coil part moves in a vertical direction so that a space between a lower surface of a top plate of the case and an upper surface of the coil part changes according to a change in a liquid level of the coolant.
