Definition - What does In-Rack Cooling mean?
In-rack cooling offers an ideal computing environment, that is, a microclimate that is thermally neutral to other parts of the room.
Techopedia explains In-Rack Cooling
In an in-rack cooling system, the airflow paths are minimal, requiring a lesser amount of fan energy. Furthermore, the exhaust air is trapped at its hottest point, which maximizes the cooling coil's delta T.
Based on the product, this efficient cooling system utilizes refrigerant or chilled water as the cooling medium. Even though there are exceptions, most products tend not to bring liquid into the server rack. The air conditioner, along with the water connections, is encased in a nearby, but independent, enclosure. The device at the rack level continues to be air cooled. For chilled water supply in addition to best heat rejection, chilled water units require connections to the chillers.
In-rack cooling is versatile, quick to employ and attains high density with additional expenditures.
In-rack cooling offers the following benefits:
- Agility: Can easily afford any power density
- System availability: Close coupling results in the removal of hot spots as well as vertical temperature gradients
- Lifecycle expenditure: Standardized elements and a pre-engineered system minimize or eradicate planning and engineering
- Serviceability: Standardized elements lessen the need for technical expertise
- Manageability: Effortless browsing through a menu interface and is good at providing predictive failure analysis
