Abstract: Removal of heat generated by IT equipment in a data centre is facilitated by heat changing units mounted to back sides of open computer storage racks in which the IT equipment is mounted. One or more fans in the IT equipment generate an air flow across the IT equipment, and a heat exchanging unit mounted to the back side of the rack transfers heat in the air flow to a fluid coolant flowing through the heat exchanging unit. The heat exchanging unit has an air back pressure that does not significantly impede the air flow across the IT equipment, and a low fluid pressure drop for the fluid coolant, so that a cold air exhaust temperature of air exiting the heat exchanging unit is less than or equal to the room air temperature of input air entering the computer rack.

Abstract: A computer data center having multiple open computer hardware storage racks. Each rack includes multiple computer hardware components horizontally rack-mounted in a front side of the rack, and a heat exchanging unit vertically mounted to a back side of the rack. A first cooling circuit interconnects the heat exchanging units of at least some of the computer hardware storage racks. At least a first rack and a second rack are arranged back to back in the computer data center, with a first heat exchanger unit of the first rack facing a second heat exchanger unit of the second rack.

Abstract: The present disclosure relates to a mobile data center unit, which is adapted to house at least one rack being designed to provide storage space for electronic equipment. The mobile data center unit is equipped with passive cooling means in order to provide dissipation of heat being generated by the electronic equipment.

Abstract: The invention relates to a structure of a multi-storey computer center building, which is suitable for accommodating a multiplicity of racks, each of which has storage space for computer hardware. The building has a first cooling circuit in order to dissipate heat generated by the computer hardware and the first cooling circuit is designed to supply at least some of the racks with a coolant. The first cooling circuit is also designed to remove the heated coolant from at least some of the racks. And, the racks have heat exchanger devices, which are suitable for transferring the generated heat to the coolant.
