Document Type and Number:
Japanese Patent JP2023111798
Kind Code:
A
Abstract:
To provide a cooling device that even when a pump stops, supplies a coolant to a cooling unit to continue cooling.SOLUTION: A cooling system 100 includes a cooling device 10 including a first cooling unit 11A, a second cooling unit 11B, a first pump unit 112A, a second pump unit 12B, a branch unit 3, a first flow passage unit 20A, a second flow passage unit 20B, a merging unit 4, and a connection unit 2. The branch unit divides a coolant into two. The first flow passage unit connects the first cooling unit with the first pump unit and one of the divided coolant passes through the first flow passage unit. The second flow passage unit connects the second cooling unit with the second pump unit and the other of the divided coolant passes through the second flow passage unit. The merging unit merges together the one and the other coolants that have passed through the first flow passage unit and the second flow passage unit, respectively. The connection unit connects fluidically the first flow passage unit and the second flow passage unit between the branch unit and the merging unit.SELECTED DRAWING: Figure 1
