Abstract: A cooling device includes a cooling assembly which includes a cold plate extending in a first direction, a pump and a tank on one side of the cold plate in a second direction perpendicular to the first direction, and a partition extending in the first direction and covering the cold plate on one side in the second direction. The cold plate and the partition define a first refrigerant flow path through which a refrigerant flows. The pump includes a pump chamber in which an impeller is housed, the impeller moving the refrigerant. The tank includes a tank chamber in which the refrigerant flows. The pump chamber and the tank chamber communicate with each other through a first tank hole portion. The partition includes a first hole portion through which the first refrigerant flow path and the tank chamber communicate. The first tank hole portion is provided on one side in the first direction with respect to the first hole portion.

Abstract: In an air blower, an exhaust extends in a first direction that is a radial component of an impeller, and includes fins. Assuming that a distance from a line segment extending from a central axis in the first direction to an array of the fins upstream of an airflow caused by rotation of the impeller is a first predetermined distance, at least a portion of the fins are disposed in a first region upstream from the first predetermined distance and in a second region downstream from the first predetermined distance. The distance between the fins in the first region is shorter than the distance between the fins in the second region.

Abstract: A centrifugal fan includes a motor, an impeller, and a housing. The motor includes a rotary portion that rotates about a vertical center axis. The impeller is fixed to and rotates together with the rotary portion. The housing accommodates the motor and impeller. The rotary portion includes a rotor holder with a magnet. The impeller includes circumferentially disposed blades and a blade support portion that supports the blades on an outer side. The housing includes an inlet port axially penetrating an upper surface of the housing and an outlet port radially penetrating a side surface of the housing. The blade support portion includes an accommodating portion that opens upward and that accommodates a balance adjustment member. The accommodating portion is disposed on a radial-direction inner side of the blades and between an upper end and a lower end of the blades in an axial direction.

Abstract: A cooling unit includes a cold plate extending in a horizontal direction, a tank defining a tank chamber that stores a refrigerant, the tank including an outer tank surface and an inner tank surface, and a pump defining a pump chamber, the pump including an outer pump surface and an inner pump surface. The pump chamber is spaced away from and outside of the tank chamber. A portion of the outer tank surface and a portion of the outer pump surface are directly adjacent to one another in the horizontal direction. The pump chamber accommodates a rotating body that transfers the refrigerant. An upper end of the tank chamber in a first direction perpendicular to the horizontal direction is positioned higher than an upper end of the pump chamber in the first direction.
