Heat Dissipation Unit, Air-to-Liquid Heat Exchanger | HDU

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.

Key Reasons to Use a Motivair® HDU™

• Location of liquid cooled system prevents water from being plumbed to the computers
• Current cooling solution does not have enough capacity to absorb heat from the liquid cooled computer system
• Chilled or cool water is not available at the site
• Beta testing of liquid cooled computer systems prior to full scale deployment.
