REFRIGERANT SUPPLY DEVICE, PHASE CHANGE COOLING DEVICE IN WHICH SAME IS USED, AND REFRIGERANT SUPPLY METHOD

摘要

In a phase change cooling device in which a plurality of heat-generating elements are the objects to be cooled, cooling performance declines due to fluctuations in the calorific values of the plurality of heat-generating elements. Therefore, this refrigerant supply device has a storage tank for storing a refrigerant fluid being circulated by a drive pump, and a refrigerant fluid amount adjustment means for controlling the flow rate of the refrigerant fluid flowing out from the storage tank to a heat-receiving unit. The storage tank is provided with a branch outflow part, the branch outflow part being provided upward of the refrigerant fluid amount adjustment means, an in-tank refrigerant fluid stored in the storage tank being caused to flow out to another storage tank located below the storage tank.
