    • A video signal circuit of a notebook computer includes a north bridge chipset, a control module, a VGA port, an A/D converter, a selection module, and a control unit. The north bridge chipset is coupled to the control module and the selection module. The VGA port is coupled between the control module and a display device and a processing device. The A/D converter is coupled between the control module and the selection module. The selection module is coupled to an LCD of the notebook computer. The control unit is coupled to the selection module and the control module. The video signal circuit can be controlled to send a first analog and digital video signals generated by the north bridge chipset to the displaying device and the LCD respectively, or receive a second analog video signal from the processing device and display it on the LCD.
    • 笔记本电脑的视频信号电路包括北桥芯片组,控制模块,VGA端口,A / D转换器,选择模块和控制单元。 北桥芯片组耦合到控制模块和选择模块。 VGA端口耦合在控制模块与显示设备和处理设备之间。 A / D转换器耦合在控制模块和选择模块之间。 选择模块耦合到笔记本计算机的LCD。 控制单元耦合到选择模块和控制模块。 视频信号电路可以被控制以将由北桥芯片组产生的第一模拟和数字视频信号分别发送到显示装置和LCD,或者从处理装置接收第二模拟视频信号并将其显示在LCD上。

    • A cabinet includes a front panel, a rear panel defining a plurality of vent ports, and a top wall defining a plurality of apertures therein adjacent to the front panel. A rack having a plurality of shelves is mounted in the cabinet for holding electronic devices. At least one intake fan is installed on a top portion of the cabinet below the apertures of the top wall, and at least one exhaust fan installed on a bottom portion of the cabinet adjacent to the rear panel. The intake fan directs airflow downward into the cabinet for cooling the electronic devices. The exhaust fan directs airflow heated-exchanged with the electronic devices out of the cabinet via the vent ports of the rear panel.
    • 机柜包括前面板,限定多个排气口的后面板,以及限定与前板相邻的多个孔的顶壁。 具有多个搁架的机架安装在机柜中用于保持电子设备。 至少一个进气风扇安装在位于顶壁的孔下方的机壳的顶部,并且至少一个排气风扇安装在机柜的与后面板相邻的底部。 进气风扇将气流向下引导到机柜中以冷却电子设备。 排气风扇通过后面板的排气口将与电子设备进行加热交换的气流引导出机柜。
