Cooling assembly and method for cooling a plurality of heat-generating components

A method for cooling a plurality of heat-generating components, the method comprising:

• mounting a plurality of liquid cooling units on the heat-generating components so that each liquid cooling unit is in thermal contact with a corresponding one of the heat-generating components to be cooled, each liquid cooling unit comprising a liquid inlet for receiving a heat-transfer liquid and a liquid outlet for discharging the heat-transfer liquid;
• fluidly connecting one or more of the liquid cooling units to form a plurality of groups of liquid cooling units, the liquid cooling units of a same group being fluidly connected in parallel to one another,
• fluidly connecting two or more groups to form at least one cluster of groups of liquid cooling units, the groups of a same cluster being fluidly connected in series;
• and
• fluidly connecting the at least one cluster to a main liquid inlet for delivering the heat-transfer liquid to the liquid inlets of the liquid cooling units and to a main liquid outlet for receiving the heat-transfer liquid from the liquid outlets of the liquid cooling units, each heat-generating component corresponds to a server in a datacenter,
• the method further comprising:
• fluidly connecting two or more groups to form at least one cluster of groups of liquid cooling units comprising:
• disposing a first group in thermal contact with first corresponding servers having a first real or expected power consumption level, and
• disposing a second group in thermal contact with second corresponding servers having a second real or expected power consumption level lower than the first real or expected power consumption level, the second group being downstream of the first group within the cluster, the first and second servers being identified based on the power consumption data indicative of the respective servers' real or expected power consumption levels.
