Abstract: Each fin of a heat sink includes a main fin connected to a core and extending radially outwards, and a pair of branch fins extending radially outwards from a branch point at a radially outer end of the main fin. Among a plurality of fins, in each of three fins which are adjacent in the circumferential direction, a width of an end portion of the main fin viewed along the center axis expands radially outwards at an angle which is larger than an expanding angle of the pair of branch fins. A difference between a distance from the center axis to the branch point in the center one of the fins and a distance from the center axis to the branch point in each of the other two fins is equal to or larger than a width of a root of the main fin in the center radiating fin.

Abstract: A cooling device includes: a cold plate; a radiator; a pump; a first tank; and a second tank. The cold plate has a first cooling medium flow passage. The radiator has fins and pipes forming a second cooling medium flow passage. The pump circulates a cooling medium. The first tank is coupled to one ends of the pipes. The second tank couples the other ends of the pipes to the pump. The radiator is disposed on the cold plate. The cold plate has a bottom wall portion, a top wall portion, a side wall portion, an internal space, an inlet port, and an outlet port. The bottom wall portion has blades, and an inner peripheral wall of the side wall portion has a first bent portion.

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.
