A cooling system includes a first module, a second module provided at a different position in a depth direction of a housing with respect to the first module, a third module provided at a different position in a width direction of the housing with respect to the first module and the second module, an upstream side tube configured to supply a cooling medium to a cooling member of the first module, a downstream side tube configured to supply the cooling medium passed through the cooling member of the first module to a cooling member of the second module, and a branch tube configured to branch from the downstream side tube and supply the cooling medium to a cooling member of the third module.

Cooling system and electronic device

A joint member includes a joint main body configured to include a flow path portion formed and an opening portion communicating with the flow path portion, and a tube member configured to include an end portion inserted into the opening portion of the joint main body and joined to the joint main body by brazing. The joint main body includes a step portion on which the end portion of the tube member inserted into the opening portion abuts. The tube member includes an annular recessed portion recessed from an outer peripheral surface of the tube member and formed on a flexible tube side with respect to an end surface on a joint main body side.

A cold plate has, on a surface thereof, an attachment surface for contacting a cooling object, and has, in the interior thereof, an accommodating portion that accommodates a cooling medium. The cold plate is provided with a first opening that communicates with the accommodating portion, a body-side connection pipe is connected to the first opening, a tube-side connection pipe, which has a bendable tube connected to one end thereof, is connected to the body-side connection pipe. The body-side connection pipe and the tube-side connection pipe are connected so as to be able to rotate about the pipe axis.

Cold plate, device, and connection tube for cold plate

A cooling system including a cooling unit that cools a heat-generating component; a supply connection tube that is connected to the cooling unit and that supplies a cooling medium to the cooling unit; and a discharge connection tube that is connected to the cooling unit and that discharges the cooling medium from the cooling unit, wherein the supply connection tube and the discharge connection tube have different lengths.

Cooling system, module, and device

A serving rack cooling device. The device includes a rack; an enclosure provided inside the rack; a module provided inside the enclosure; a main pipe provided in the rack; a branching tube connected to the main pipe; a cooling unit that cools a heat-generating component mounted on the module; a first connection tube that connects the branching tube with the cooling unit; and a plurality of module connection portions that are provided inside the enclosure and to which the module is connected. The enclosure can slide in a state in which the module is connected to the module connection portion, and the cooling unit and the branching tube are connected by the first connection tube.

Server rack cooling device

A refrigerant relay deviceis provided with a casing, a first refrigerant inflow opening, a first refrigerant outflow opening, and refrigerant inflow piping. The casing retains liquid-phase refrigerant and gas-phase refrigerant. The liquid-phase refrigerant is made to flow into the casing through the first refrigerant inflow opening. The gas-phase refrigerant is made to flow out to the outside of the casing through the first refrigerant outflow opening. In the refrigerant inflow piping, one end is connected to the first refrigerant inflow opening and an openingis formed at the other end. The liquid-phase refrigerant flowing into the first refrigerant inflow opening is made to flow into the casing through the refrigerant inflow piping from the opening. The opening is positioned so as to face the bottom partof the casing.

Cooling device

A cooling system includes a heat absorbing device which has a first pipe port and absorbs heat discharged from equipment by using refrigerant; a radiator which has a second pipe port placed higher than the first pipe port and cools the refrigerant; a first flexible pipe whose one end is connected with the first pipe port and whose another end is connected with the second pipe port and through which the refrigerant flows and which can bend freely; and a loading table having a surface which becomes higher in a vertical direction as approaching from one end of the surface to another end, and on which the first flexible pipe is placed so as to become higher in the vertical direction as approaching from a side of the first flexible pipe, which is connected with the first pipe port, to a side of the first flexible pipe which is connected with the second pipe port.
