ABSTRACT:
Disclosed herein is a data center having a plurality of liquid cooled computer systems. The computer systems each include a processor coupled with a cold plate that allows direct liquid cooling of the processor. The cold plate is further arranged to provide adapted flow of coolant to different portions of the processor whereby higher temperature regions receive a larger flow rate of coolant. The flow is variably adjusted to reflect different levels of activity. By maximizing the coolant temperature exiting the computer systems, the system may utilize the free cooling temperature of the ambient air and eliminate the need for a chiller. A data center is further provided that is coupled with a district heating system and heat is extracted from the computer systems is used to offset carbon emissions and reduce the total cost of ownership of the data center.
