| 20090016019 | AIRFLOW CONTROL AND DUST REMOVAL FOR ELECTRONIC SYSTEMS - Airflow control and dust removal systems and methods are disclosed. In one embodiment, a plurality of blade servers is mounted in a chassis. A blower generates airflow through the chassis. Air enters the chassis uniformly across the blade servers and flows in parallel through the servers. An airflow directing mechanism is provided for allowing airflow through a selected one of the blade servers while reducing or closing airflow to the other blade servers, to individually clean and remove dust from the selected blade server. The airflow directing mechanism may include a movable vane actuated by a rotary or linear solenoid to selectively block airflow ports of the servers. The vane may be held in a closed position, assisted by an electromagnet. The airflow directing mechanism may alternatively comprise a rolled shade having a pattern of openings. The position of the rolled shade may be controlled to align openings in the shade with airflow ports in the servers, to control which servers airflow may pass through. | 01-15-2009 |
| 20090021270 | CAPACITIVE DETECTION OF DUST ACCUMULATION IN A HEAT SINK - A system and method for electronically detecting the accumulation of dust within a computer system using a capacitive dust sensor. The dust detection system may be implemented on a smaller computer, such as an individual PC, or in a more expansive system, such as a rack-based server system (“rack system”) having multiple servers and other hardware devices. In one embodiment, each server in a rack system includes a capacitive sensor responsive to the accumulation of dust. The capacitive sensor may include one or more capacitive plates integral with a heatsink. As dust collects on the capacitive plates, the capacitance increases. When a capacitance setpoint is reached, indicating the dust has reached a critical level, an alert is generated. The alerts may be received by a management console for the attention of a system administrator. Each alert may contain the identity of the server generating the alert, so that the system administrator knows which server(s) are to be removed for cleaning. | 01-22-2009 |
