标准范围

IEC 62610-6:20 20根据IEC 60297和IEC 60917系列处理机柜的热管理，提供了再循环比和旁通比的兼容测量方法，这些测量方法是用于定义强制空气冷却中气流质量的指标，通常可应用于用于安装子机架和/或基于机箱的设备的室内机柜。本文件包含以下内容:a)在机柜的冷却中的再循环和旁路流速的定义，b)再循环比RC的水平，c)用于安装在机柜中的强制空气冷却子机架和/或基于机箱的设备的再循环比RCs的公式的定义，d)整个机柜的再循环比RCr和旁通率BPr的定义公式，e)计算再循环比RCs、RCr和旁通比BPr所需的各温度的测量方法要求。本文件的目的是提供:？对于机柜的设备集成商和开发设计者来说，有效和正确地确定规格的标准，以及？对于机柜供应商，安装在机柜中的子机架和/或基于机箱的设备的气流再循环率的测量和分类方法。

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.
