A cooling apparatus includes a cold plate made of a metal, a casing, a pump, a ground wire, and a conductive component. The pump includes a motor to drive an impeller, and a circuit board to control the motor. The circuit board is connected to the ground wire. The conductive component electrically connects the cold plate to the ground wire.

Cooling apparatus and cooling system

A liquid feeder includes a pump which is prevented from idling, and a replenisher including a cylinder that is a bottomed tube including an opening on a side adjacent to a communication flow path, the opening being connected to the communication flow path, and that is capable of accommodating a liquid in at least a portion of the cylinder, a seal that is housed in the cylinder in a movable manner along the cylinder, and seals the liquid in the cylinder, and a pressurizer to pressurize the seal toward a pump chamber.

Liquid feeder

A cooling device includes at least two cooling units, each cooling unit including a plate-shaped cold plate extending in a horizontal direction, a radiator extending in a first direction perpendicular to the horizontal direction and having a plurality of plate-shaped fins which, on the cold plate, is disposed parallel to a second direction perpendicular to the first direction, and a pump which supplies a refrigerant liquid to the cold plate and the radiator, in which the pump is adjacent to the radiator and is disposed in the second direction of the radiator, and the pump of one first cooling unit of the two cooling units faces the other second cooling unit of the two cooling units in the second direction or in a third direction orthogonal to the first direction and the second direction.
