摘要： A container includes a first container portion and a second container portion. The first container portion includes a flow path therein through which liquid passes. The second container portion is connected to the flow path and is capable of containing the liquid. The second container portion includes a reservoir and a changing assembly. The reservoir can store the liquid in at least a portion thereof. The changing assembly changes the volume of the reservoir according to a change in the liquid.

摘要： A cold plate includes an opposing portion, a cover portion, and a heat exchange chamber. The opposing portion opposes a heat generating component on one side in a first direction. The cover portion is arranged on another side of the opposing portion in the first direction. The heat exchange chamber includes at least the opposing portion and the cover portion to conduct heat from the heat generating component to a refrigerant through the opposing portion. The opposing portion includes a first cooling surface and a second cooling surface. The first cooling surface is provided on the one side in the first direction. The second cooling surface is provided on the one side in the first direction. The second cooling surface is spaced away from the first cooling surface in the first direction.

摘要： A fluid machine includes a flow path including an outflow port of a fluid, a first portion through which the fluid flows from the other side to one side in a first direction, and a second portion through which the fluid flows. The second portion is located between one end of the first portion in the first direction and the outflow port. The fluid machine further includes a check valve portion that is movable along the first direction in the first portion, and is located at a first position at which the one end is closed, a second position that is located on one side in the first direction and through which the fluid can circulate between the first and second portions, and a third position at which the one end is closed and that is located on another side in the first direction with respect to the first position.

摘要： A cooling assembly is connectable with a cold plate that comes into thermal contact with a heat source, and includes a first manifold, a second manifold, and a radiator. The first manifold causes a refrigerant having circulated through a first pipe to flow out from outflow ports toward the cold plate. In the second manifold, the refrigerant flowing into inflow ports from the cold plate circulates through a second pipe. In the radiator, the refrigerant having circulated through the second pipe circulates through the flow paths arranged side by side at intervals. Each of the first and second pipes opposes a portion of the radiator in the first direction.

摘要： A motor includes a shaft, a bearing that rotatably supports the shaft, and a hub fixed to the shaft. The shaft includes a first shaft portion extending in an axial direction, a second shaft portion projecting axially upward from an axially upper end surface of the first shaft portion and including a diameter smaller than that of the first shaft portion, and a screw hole recessed axially downward from the axially upper end surface. The hub includes a shaft fixing hole into and in which the second shaft portion is inserted and fixed. An outer surface of the second shaft portion includes a first region, and a second region axially above the first region, and including surface roughness smaller than that of the first region.
