Publication number: 20180073824Abstract: An airflow sensor for a heat sink has a first portion having a first electrical point of contact, a second portion have a second electrical point of contact, and a deformable portion made of an electroactive material electrically coupled to the first and second portions. The deformable portion has first electrical properties measured between the first and second electrical points of contact when there is no airflow and the deformable portion is in a first position, and has second electrical properties different than the first electrical properties when a source of airflow blows air against the deformable portion, thereby causing the deformable portion to extend to a second position farther away from the source of airflow than the first position. The airflow sensor can be incorporated into a heat sink for an electronic component.Type: ApplicationFiled: November 15, 2017Publication date: March 15, 2018Inventors: William J. Anderl, Bret P. Elison, Phillip V. Mann, Chelsie M. Peterson

Publication number: 20170160116Abstract: An airflow sensor for a heat sink has a substantially flat base portion and a deformable upper portion electrically coupled to the base portion that contacts a conductive 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 the airflow. The difference in the point of contact is measured, and is used to characterize the airflow sensor for different airflows. Data from the airflow sensor can then be logged during system operation. When needed, the data from the airflow sensor can be read from the log and converted to airflow using the airflow sensor characterization data. In this manner the airflow through a heat sink may be dynamically measured, allowing analysis and correlation between system events and airflow through the heat sink.Type: ApplicationFiled: December 3, 2015Publication date: June 8, 2017Inventors: William J. Anderl, Bret P. Elison, Phillip V. Mann, Chelsie M. Peterson
