High-density racks bundle enormous performance in a very small space\u2014often over 20 kW per rack, and far beyond that in AI environments. These power densities present significant challenges for conventional air cooling systems. This is where the strength of liquid cooling becomes apparent: technologies such as direct-to-chip cooling or immersion cooling with dielectric fluids dissipate the resulting waste heat directly at the source\u2014efficiently, reliably, and in a space-saving manner. This not only enables stable operation but also ensures that available data center space is used more sustainably. High-density racks, liquid cooling, and a holistically planned data center design form the technological foundation to meet the growing demands of modern IT and AI environments.      \t\t\t\t\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-32a78c06 e-con-full e-flex e-con e-child\" data-id=\"32a78c06\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-646239e4 elementor-widget elementor-widget-button\" data-id=\"646239e4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Homepage<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-20e3e75b elementor-widget elementor-widget-button\" data-id=\"20e3e75b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/firstcolo.net\/en\/knowledge\/glossary\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Glossary<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>What is Liquid Cooling?
