Cooling unit and electronic equipment

摘要

A cooling unit includes a radiator, a rigid supply pipe which is connected to the radiator, and in which a refrigerant that is air-cooled by the radiator flows, a plurality of open nozzles provided at the supply pipe to correspond to the respective plurality of heat-generating components, a plurality of heat receiving units that are mounted to the respective plurality of heat-generating components and connected to the respective open nozzles, and allow a refrigerant supplied from the open nozzles to flow through internal channels, and a plurality of return pipes each of which is provided for each of the heat receiving units and joined to the heat receiving unit, and returns the refrigerant discharged from the heat receiving unit to the radiator, wherein the respective heat receiving units are connected to the supply pipe to be relatively displaceable, and the respective return pipes are connected to one another in series and relatively displaceably.
