This technical specification outlines interface dimensions and cooling performance guidelines for cabinets, utilizing water-supplied heat exchangers. For a precise definition of these interface dimensions and cooling performance guidelines, only cabinets have been considered in accordance with IEC 60297 (19 in) and IEC 60917 (25 mm) standards.
As the cooling performance is directly linked to air and water volume flows and temperatures, this document provides guidelines for two structural interface levels: Interface level 1 and 2, which are incorporated into cabinets. The third interface level is only described through main interfaces but lacks detailed dimensions and cooling performance guidelines. This level requires intricate details for the water supply ducting within the cabinet and down to the component heat sinks on boards within subracks. Therefore, while the principle is shown as applicable for individual design solutions, it does not provide detailed specifications.
