Dry cooling arrangement for a datacenter

A datacenter dry cooling system for cooling a heat generating source, comprising:

• a first closed loop arrangement configured to convey and circulate a first cooling fluid through the heat generating source, the first closed loop arrangement comprising:
• a dry cooler unit comprising a frame enclosing an air-to-liquid heat exchanger and an evaporating pad, the air-to-liquid heat exchanger adapted to receive the circulating first cooling fluid from the heat generating source and configured to dissipate a heat imparted on the first cooling fluid by the heat generating source to re-cool the first cooling fluid, and
• a first pump adapted to receive the re-cooled first cooling fluid from the air-to-liquid heat exchanger and forward the re-cooled first cooling fluid to the heat generating source;
• a second cooling fluid open loop arrangement configured to convey a second cooling fluid from a second cooling fluid source, the second cooling fluid open loop arrangement comprising:
• a second fluid access component adapted to supply a flow of the second cooling fluid from the second cooling fluid source to the second cooling fluid open loop arrangement, and
• a second cooling fluid valve fluidly coupled to the second cooling fluid open loop arrangement to supply the flow of the second cooling fluid onto the evaporating pad,
• the evaporating pad disposed on an outer lateral side of the frame of the dry cooler unit and at an input airflow side of the air-to-liquid heat exchanger to receive the supplied flow of the second cooling fluid for cooling dampening,
• at least one fan adapted for causing an air flow through the evaporating pad and through the air-to-liquid heat exchanger,
• a leak detector sensor configured to detect a leakage amount of the second cooling fluid from the evaporating pad, and
• an electronic controller communicatively coupled to the first pump, the second fluid access component, the second cooling fluid valve, the at least one fan, and the leak detector sensor, the electronic controller configured to:
• determine a target amount of the second cooling fluid to be supplied to the evaporating pad based on the detected second cooling fluid leakage amount from the leak detector sensor;
• and
• control, based on the determined second cooling fluid target amount, a flow rate of the first pump, a flow rate of the second fluid access component, a flow rate of the second cooling fluid valve, and/or a rotation speed of the at least one fan.
