Abstract: Provided is a graphite composite film that is capable of attaining both a measure against heat and a measure against electromagnetic noise and that has excellent high-frequency electromagnetic wave shielding performance. The graphite composite film is configured to include a graphite layer, a first electrically conductive adhesive layer, a first metal layer containing a first metal, and a second metal layer containing a second metal disposed in this order. With an arithmetic average roughness of a surface on a first electrically conductive adhesive layer-disposed side of the first metal layer defined as Ra1 and an arithmetic average roughness of a surface of the second metal layer opposite from a surface on a first metal layer-disposed side of the second metal layer defined as Ra2, at least one of the Ra1 or the Ra2 is less than or equal to 50 nm.

Abstract: A fiber sheet having first and second surfaces and spaces therein is prepared. The spaces of the fiber sheet are impregnated with silica sol containing water glass and ethylene carbonate. Silica gel is formed by causing the silica sol with which the spaces of the fiber sheet is impregnated to gel while a difference between respective temperatures at the first and surfaces of the fiber sheet is equal to or larger than 50° C. The silica gel is hydrophobized, thereby providing a thermal insulation sheet. In the thermal insulation sheet, compressibilities of the first and second surfaces for a predetermined pressure applied thereto are different from each other. The thermal insulation sheet may be disposed between two battery cells so as to prevent one sell from influencing the other even if the one expands.

Abstract: An object of the present invention is to provide a thermal insulator which is easily position-adjusted when disposed in equipment. A plurality of projections are provided on at least one surface of thermal insulator including nonwoven fabric and xerogel in interior spaces of nonwoven fabric. With this configuration, fine positioning or the like is easily performed when thermal insulator is disposed, and a thickness increases by a height of projections, so that a thermal insulation effect can be improved. Thus, the thermal insulator can be used for thermal insulation of various types of equipment.

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.

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: The present disclosure is intended to provide a thermal insulation sheet that is resistant to being damaged even if enlarged in shape, as well as a multilayer thermal insulation sheet including such a thermal insulation sheet. The thermal insulation sheet includes a thermal insulator made of a nonwoven fabric that supports a xerogel in internal spaces. The thermal insulator has a plurality of through holes in an internal region in a plan view. Protective sheets are disposed on two respective surfaces of the thermal insulator. The protective sheets are joined together at a periphery of the thermal insulator and through inside the through holes.

Abstract: Provided is a graphite composite film that is capable of attaining both a measure against heat and a measure against electromagnetic noise and that is less likely to cause degradation of electromagnetic wave shielding properties. The graphite composite film includes a graphite layer, a first electrically conductive adhesive layer, and a metal layer containing a first metal disposed in this order. A first rust-proofing layer is interposed between the first electrically conductive adhesive layer and the metal layer, and a second rust-proofing layer is disposed on a surface of the metal layer opposite from a surface on a first rust-proofing layer-disposed side of the metal layer.
