摘要： An emergency cooling system for cooling an object certainly and rapidly in case a temperature of the object is accidentally raised abnormally. A loop thermosyphon is formed by connecting an evaporating portion with a condensing portion through a vapor pipe and a return pipe in a manner to form a cyclic conduit. A condensable working fluid circulates within the loop thermosyphon to be evaporated by a heat of the cooling object at the evaporating portion, and to be condensed at the condensing portion to radiate the heat conducted from the cooling object. A switching valve is disposed on the return pipe to selectively allow the working fluid in a liquid phase to be returned from the condensing portion to the evaporating portion. Heat transfer pipes to which the heat of the cooling object is conducted are arranged in the evaporating portion. Heat transfer protrusions are formed on an inner wall of the heat transfer pipe to penetrate through dews of the working fluid, and a preheating portion to which the heat of the cooling object is conducted is formed within a portion of the return pipe connected to the heat transfer pipe.

摘要： 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.

摘要： 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.

摘要： 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.
