Book excerpt: Liquid cooling for data centers is a technological solution that helps keep computer hardware and other electronic devices running at optimal temperatures. It helps reduce costs associated with energy consumption by cooling the data center’s internal environment without the need for traditional air conditioning systems. Liquid cooling systems are built with a variety of components, including heat exchangers, pumps, hoses, and cooling towers. These components work together to exchange the heat generated from the components in the data center with a coolant, such as water or a refrigerant. The coolant is then cycled through the system and released into the environment, cooling the system and providing a more consistent temperature for the data center. Liquid cooling solutions provide an efficient and cost-effective means for data centers to maintain their optimal temperature and reduce the amount of energy required to run the system.
