Abstract: A temperature measuring device includes a heat pipe having a container in which a working fluid is enclosed, a temperature sensor that detects a temperature of the heat pipe, and a wire portion connected to the temperature sensor, in which the heat pipe receives heat from a plurality of heat sources.

Abstract: A cold plate includes a main body in contact with a heat source. The main body has: an inflow hole through which a refrigerant flows in; an outflow hole through which the refrigerant flows out; and an internal space communicating with the inflow hole and the outflow hole and through which the refrigerant flows, and includes: a first heat exchange layer in the internal space; and a second heat exchange layer in the internal space. The first heat exchange layer and the second heat exchange layer are laminated in a thickness direction of the first heat exchange layer and of the second heat exchange layer.

Abstract: A power supply cable includes a heat pipe including a container and an insulating layer formed on an outer periphery of the container, and a plurality of power lines disposed radially outside the heat pipe and including conductive wires.

Abstract: A cold plate includes a housing, which in turn includes a metal base plate and a resin cover. The metal base plate includes: a base part; and a heat exchange part that transfers heat absorbed from a heating element to a refrigerant. The resin cover includes an outer wall part joined to the base part. The housing has: an internal space, surrounded by the base part and the outer wall part, in which the heat exchange part is disposed; an inflow hole that communicates with the internal space and into which the refrigerant flows; and an outflow hole that communicates with the internal space and through which the refrigerant flows out.

Abstract: A cold plate includes: a metal base plate having a first surface, a second surface on a side opposite the first surface, and fins disposed in parallel on the first surface; and a topped cylindrical resin cover covering the fins. The first surface has a recessed portion recessed toward the second surface. The topped cylindrical resin cover is heat-fused to the metal base plate on an inner surface of the recessed portion.

Abstract: A heat pipe includes a flat container having an internal space in which a working fluid is sealed and a flat surface facing the internal space, and a wick disposed in the internal space. The wick includes a first wick having a plurality of first voids and a second wick having a plurality of second voids. The first wick rises from the flat surface and is fixed to the flat surface. The second wick is formed of a sintered body of powders and covers a surface of the first wick. Each of the plurality of second voids is smaller on average than each of the plurality of first voids.

Abstract: A method for forming a dihydride rich amorphous silicon semiconductor film suitable for use as a window material of solar cells only from a silicon material, which comprises decomposing a gaseous mixture composed of disilane, a dopant capable of imparting p-type electrical conductivity and a diluent gas by applying a glow discharge energy, and thereby forming a semiconductor film having an optical band gap of at least 1.8 eV, preferably more than 1.9 eV, on a substrate.
