摘要

An information handling system includes a fan to cool a component of the information handling system, and a sensor device. The fan includes a first fan inlet, a second fan inlet, and a fan outlet. The fan is configured to draw air into the first and second fan inlets and to blow air out the fan outlet. The sensor device includes a sensor inlet, a sensor outlet, and a cover. The sensor is coupled to the fan with the first fan inlet collocated with the sensor outlet such that air drawn into the first fan inlet is first drawn through the sensor inlet. The cover is configured in a first position to cover the sensor inlet to permit no air flow through the sensor inlet and in a second position to uncover the sensor inlet to permit air to flow through the sensor inlet.

說(shuō)明書(shū)

FIG. 2 illustrates an information handling system 200 similar to information handling system 110. Information handling system 200 includes a heat-generating component 210 installed within a case 220. Component 210 is cooled by a cooling fan 230. Cooling fan 230 includes a fan inlet 232 to receive cool air, and one or more fan outlet, not illustrated, that is located to blow the cool air over component 210. The cool air removes heat from component 210 and the heated air is blown out of one or more case outlet 222, thereby removing the heat from component 210. In a particular embodiment, fan inlet 232 is situated at a bottom side of case 220, such that ambient air is drawn into fan 230 via the fan inlet, and FIG. 2 will be understood to be a bottom-view.
