AI summary

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.
