    • A temperature isolation duct in a computer system comprising a chassis securing a circuit board and a fan system that draws air through the chassis, and a heat-generating component is mounted on the circuit board and exposed to the air flow. The hot air duct passively directs air heated by the heat-generating component from a single hot air duct inlet in direct downstream alignment with the heat-generating component to a single hot air duct outlet. A thermal sensor is secured within, or in direct alignment with, the hot air duct near the duct outlet for sensing the temperature of air flowing through the hot air duct and generating a temperature signal. A controller is in electronic communication with the thermal sensor for receiving the temperature signal and in electronic communication with the fan system for sending a fan speed control signal.
    • 计算机系统中的温度隔离管道,包括固定电路板的底盘和通过底盘吸入空气的风扇系统,以及发电部件安装在电路板上并暴露于空气流中。 热风管道将发热部件加热的空气从发热部件直接下游对准,将单个热风管道入口导向单个热风管道出口。 热传感器固定在管道出口附近的热空气管道内或与其直接对准,以便感测流过热风管道的空气的温度并产生温度信号。 控制器与热传感器进行电子通信,用于接收温度信号,并与风扇系统进行电子通信,以发送风扇速度控制信号。
