摘要：An airflow sensor for a heat sink has a substantially flat base portion and adeformable upper portion electrically coupled to the base portion that contacts aconductive strip. As airflow increases, the deformable upper portion deforms and moves
away from the source of airflow, which moves the point of contact between the
deformable upper portion and the conductive strip farther away from the source of theairflow. The difference in the point of contact is measured, and is used to characterize theairflow sensor for different airflows. Data from the airflow sensor can then be loggedduring system operation. When needed, the data from the airflow sensor can be readfrom the log and converted to airflow using the airflow sensor characterization data. Inthis manner the airflow through a heat sink may be dynamically measured, allowinganalysis and correlation between system events and airflow through the heat sink.
