Abstract
A system provides cooling to an infrastructure having heat-generating units. Internal cooling units are thermally connected to the heat-generating units. An external cooling unit dissipates thermal energy of a heat-transfer fluid circulating in the internal cooling units. A cooling circuit connects the internal and external cooling units. A pump maintains a flow of the heat-transfer fluid for transferring thermal energy from the heat generating units to the external cooling unit. A reservoir thermally connected to the cooling circuit contains a phase change material (PCM) changing between solid and liquid states according to a temperature of the heat-transfer fluid. Thermal energy is transferred between the cooling circuit and the PCM depending on whether a temperature of the heat-transfer fluid is above or below a phase-change temperature value of the PCM. A supplemental cooling device thermally connected to the reservoir dissipates heat from the reservoir to the atmosphere.
