I would like to do some thermal characterization on a heatsink assy and
it would be helpful to get a "somewhat" accurate air flow measurement.
I've thought of building some ductwork and variable speed fans to
control the air across the fins but need a way to measure the air
speed, etc. I know I could spend some $$ for a lab flow meter but it
occurs to me that cars have a air flow meter in the intake system.
Could I get one of those cheaply from a salvage yard and would it work
for the sort of low air speeds (0-8mph) I want to test at? I would
need to get the hookup connection and what the signal vs flow cal
information is if its available..... The design I am working on has a
heatsink about 9" wide with 1" fins and typically we would be running
150W or so with it. I need to collect the temp rise vs air speed to
verify the design.
Thoughts welcome.
Thanks,
Jeff
