EN IEC 62610-6:2020

Mechanical structures for electrical and electronic equipment - Thermal management for cabinets in accordance with IEC 60297 and IEC 60917 series - Part 6: Air recirculation and bypass of indoor cabinets

IEC 62610-6:2020 deals with thermal management for cabinets in accordance with IEC 60297 and IEC 60917 series, provides compatible measurement methods of recirculation ratio and bypass ratio which are indicators for defining quality of airflow in the forced air cooling that can be commonly applied to indoor cabinets for mounting subrack and/or chassis-based equipment. This document contains the following: a) the definition of recirculation and bypass flow rates in the cooling of the cabinet, b) the levels of the recirculation ratio RC, c) the definition of the formula for the recirculation ratio RCs of forced air cooling subrack and/or chassis-based equipment installed in the cabinet, d) the definition formula of recirculation ratio RCr and bypass rate BPr of the entire cabinet, e) the requirements of the measuring method of each temperature necessary for calculating the recirculation ratio RCs, RCr and bypass ratio BPr. The purpose of this document is to provide: • for the equipment integrator and development designer of the cabinet the criteria for efficiently and correctly determining the specification, and • for the supplier of the cabinet the measuring and classifying method for the airflow recirculation rate of the subrack and/or chassis-based equipment installed in the cabinet.

Structures mécaniques pour équipements électriques et électroniques - Gestion thermique pour les armoires conformes aux séries IEC 60297 et IEC 60917 - Partie 6 : Recyclage et dérivation de l'air des armoires intérieures

IEC 62610-6:2020 traite de la gestion thermique pour les armoires conformément aux séries CEI 60297 et CEI 60917, fournit des méthodes de mesure compatibles du taux de recirculation et du taux de dérivation qui sont des indicateurs pour définir la qualité du flux d'air dans le refroidissement à air forcé qui peuvent être couramment appliquées aux armoires intérieures pour le montage des bacs et / ou des équipements sur châssis. Ce document contient les éléments suivants: a) la définition des débits de recirculation et de dérivation dans le refroidissement de l'armoire, b) les niveaux du taux de recirculation RC, c) la définition de la formule du taux de recirculation RCs du bac de refroidissement à air forcé et / ou des équipements sur châssis installés dans l'armoire, d) la formule de définition du taux de recirculation RCr et du taux de dérivation BPr de l'ensemble de l'armoire, e) les exigences de la méthode de mesure de chaque température nécessaire au calcul du taux de recirculation RCs, RCr et du taux de contournement BPr. Le but de ce document est de fournir: • pour l'intégrateur d'équipement et le concepteur de développement de l'armoire les critères pour déterminer efficacement et correctement la spécification, et • pour le fournisseur de l'armoire, la méthode de mesure et de classification du taux de recirculation du flux d'air d
