Claim 0:
1. A cooling system for cooling electronic equipment, the cooling system providing cooling to an infrastructure having a plurality of heat-generating units, the cooling system comprising:
a plurality of internal cooling units, at least one internal cooling unit of the plurality of internal cooling units being thermally connected to each of the plurality of heat-generating units;
an external cooling unit configured to dissipate thermal energy of a heat-transfer fluid circulating in the plurality of internal cooling units;
a cooling circuit connecting the plurality of internal cooling units and the external cooling unit;
a pump configured to maintain a flow of the heat-transfer fluid circulating in the cooling circuit, allowing to transfer thermal energy from the plurality of heat generating units to the heat-transfer fluid and allowing to transfer thermal energy from the heat-transfer fluid to the external cooling unit;
a first reservoir thermally connected to a section of the cooling circuit, the first reservoir containing a first phase change material (PCM), the first PCM changing from a solid state to a liquid state when a temperature of the heat-transfer fluid flowing in the section of the cooling circuit causes a temperature of the first PCM to increase above a phase-change temperature value, thereby causing thermal energy to transfer from the cooling circuit to the first PCM, the first PCM changing from the liquid state to the solid state when the temperature of the heat-transfer fluid flowing in the section of the cooling circuit causes the temperature of the first PCM to decrease below the phase-change temperature value, thereby causing thermal energy to dissipate from the first PCM;
a supplemental cooling device thermally connected to the first reservoir containing the first PCM and configured to dissipate heat from the first reservoir containing the first PCM to the atmosphere;
a controller configured to initiate operation of the supplemental cooling device when an ambient temperature at the infrastructure meets or exceeds a predetermined temperature threshold; and
an evaporative cooling system including a sprayer and a fan configured for directing water droplets toward the supplemental cooling device;
wherein the controller is configured to initiate operation of the evaporative cooling system when the ambient temperature at the infrastructure meets or exceeds the predetermined temperature threshold.
