Abstract:
1. A cooling unit comprising: a heat radiating section; a pump; a first heat absorbing section configured to contact a first heat-producing element and absorb heat from the first heat-producing element; a second heat absorbing section configured to contact a second heat-producing element and absorb heat from the second heat-producing element, the second heat-producing element producing heat less than the first heat-producing element; and a path in which coolant flows by the pump and circulates the coolant so that the coolant leaves the heat radiating section and returns to the heat radiating section, wherein the path flows the coolant flowed out from the pump to the first heat absorbing section, flows the coolant through the first heat absorbing section to the heat radiating section, flows the coolant through the heat radiating section to the second heat absorbing section, and flows the coolant through the second heat absorbing section, without running through the heat radiating section, to the pump using a circulation path connecting the second heat absorbing section directly to the pump.
