From liquid-cooled to air-cooled IT

Many modern High-Performance Computer (HPC) systems are being designed to be liquid cooled. These computers circulate a fluid to and from the computer’s CPU and GPU chips, removing heat and rejecting it to a dedicated building chilled water plant. In the absence of available building cooling water, the heat from the computer cooling system must be rejected to air, a process that can now be facilitated by Motivair’s Heat Dissipation Unit™ (HDU).

The Motivair HDU is connected directly to the computer cooling loop and sits adjacent to or proximate to the computer racks. Circulation pumps located inside the HDU move hot water from the computer system to the HDU’s air-cooled heat exchanger. 

High-efficiency EC fans draw cool room air across the HDU’s internal heat exchanger, removing heat from the computer cooling system. A high-powered PLC controls and monitors all aspects of HDU performance ensuring the HPC system can operate within thermal specifications and without dependence on a building water supply.
