产品详细资料
选择间隙在机柜中使用风扇时，机柜面板或其他非发热设备与每个机箱的底部和顶部屏幕区域之间应留有至少5.25英寸（13.3厘米）的间隙。外壳面板或其他非发热设备与机箱侧面和前部之间应至少有3.5英寸（9厘米）的距离。如果每个部件与机箱的底部和顶部屏幕区域保持至少1.75英寸（5厘米）的距离，并且不会阻挡进出这些屏幕区域的气流，则这些间隙产生的体积的30%可能会被非发热设备消耗，如电缆、外壳的结构部件和配线板。引导气流安装应确保强制气流通过机箱，而不是绕过机箱。在三机箱机柜中用风扇引导气流特别具有挑战性，因为风扇会产生柱效应。当机柜顶部的风扇将加热的废气从底部机箱向上拉过顶部机箱时，就会产生列效应。这可能会导致中间机箱比对流冷却条件下更热，尤其是当外壳环境温度超过86°F（30°C）时。这个问题可以通过使用挡板来引导气流来缓解。挡板在机柜前面为所有机箱创造了一个冷的进气源，而风扇则将热的排气从机柜侧面抽走。
Choosing Clearances When using fans in an enclosure, you should leave a minimum of 5.25 inches (13.3 centimeters) between enclosure panels or other non-heat-generating equipment and the bottom and top screen areas of each chassis. There should be a minimum of 3.5 inches (9 centimeters) between the enclosure panels or other non-heat-generating equipment and the sides and front of the chassis. Up to 30% of the volume created by these clearances may be consumed with non-heat-generating equipment such as cables, structural components of the enclosure, and wiring panels, provided that each component remains at least 1.75 inches (5 centimeters) away from the bottom and top screen areas of the chassis and does not block airflow to and from these screen areas. Directing Airflow The installation should ensure that forced airflow is through and not around the chassis. Directing airflow with fans in a three-chassis cabinet is particularly challenging due to the column effect caused by the fans. The column effect occurs when the fans at the top of the enclosure pull heated exhaust air from the bottom chassis up through the top chassis. This may cause the middle chassis to be hotter than under convection cooling conditions, especially if the enclosure ambient temperature exceeds 86° F (30° C). This issue can be mitigated by using baffles to direct airflow. Baffles create a source of cool intake air in front of the cabinet for all chassis while the fans draw the hot exhaust air away from the sides of the cabinet.
