3排最大70W低于70W1 5排最大90W低于90W1熱要求MVME7100模塊在55°C（131°F）環境溫度下運行時，要求最小氣流為10 CFM，均勻分布在整個電路板上，氣流從散熱器流到PMC2現場。2.3.4顯熱部件下表總結了顯著溫升的部件。這些部件應進行監測，以評估熱性能。該表還提供了部件參考代號和最大允許工作溫度。您可以通過參考代號在板上找到組件，如下一頁的圖2-1和圖2-2所示。未完全填充的電路板版本可能不包含這些組件。組件的首選測量位置可能是表中指定的連接點、外殼或環境。結溫是指由芯片上的熱裝置測量的溫度。外殼溫度是指部件頂部中心表面的溫度。空氣溫度是指部件附近的環境溫度。
3-Row 70W maximum Below 70W1 5-Row 90W maximum Below 90W1 Thermal Requirements The MVME7100 module requires a minimum air flow of 10 CFM uniformly distributed across the board, with the airflow traveling from the heat sink to the PMC2 site, when operating at a 55°C (131°F) ambient temperature. 2.3.4 Thermally Significant Components The following table summarizes components that exhibit significant temperature rises. These are the components that should be monitored to assess thermal performance. The table also supplies the component reference designator and the maximum allowable operating temperature. You can find components on the board by their reference designators as shown in Figure2- 1 and Figure2-2 on the next page. Versions of the board that are not fully populated may not contain some of these components.The preferred measurement location for a component may be junction, case, or ambient as specified in the table. Junction temperature refers to the temperature measured by an onchip thermal device. Case temperature refers to the temperature at the top, center surface of the component. Air temperature refers to the ambient temperature near the component.
