Abstract: A heat insulation sheet includes a fiber sheet having spaces therein and a silica xerogel held in the spaces of the fiber sheet. The heat insulation sheet includes a thick region and a low compressible region thinner than the thick region. A compressibility of the low compressible region is equal to smaller than 5% upon having a pressure of 0.7 MPa applied to the low compressible region. This heat insulation sheet is superior in electrical insulation properties and thermal insulation properties, and secures a predetermined distance even in a case that the heat insulation sheet receives pressures from the both sides thereof, thus providing equipment with reliability.

Abstract: A reactor device includes a coil, a magnetic core having the coil thereon, a case accommodating the coil and the magnetic core, a cooling plate fixed to the case, an insulating sheet disposed between the coil and the cooling plate, a compressible graphite sheet disposed between the coil and the cooling plate, and a screw to fix the cooling plate to the case. The case has a screw hole and an opening provided therein. The screw passes through the screw hole to fix the cooling plate to the case. The coil contacts the insulating sheet through the opening of the case. The graphite sheet contacts the cooling plate. The reactor has high cooling performance and reliability.
