Vertical Wind Tunnel
Murata Power Solutions employs a custom-designed enclosed
vertical wind tunnel, infrared video camera system and test
instrumentation for accurate airfl ow and heat dissipation analysis
of power products. The system includes a precision low fl ow-rate
anemometer, variable speed fan, power supply input and load
controls, temperature gauges and adjustable heating element.

conditions. A special optical port is used which is transparent to
infrared wavelengths. The computer fi les from the IR camera can
be studied for later analysis.
down to a host carrier board for realistic heat absorption and
spreading. Both longitudinal and transverse airfl ow studies are
possible by rotation of this carrier board since there are often
signifi cant differences in the heat dissipation in the two airfl ow
directions. The combination of both adjustable airfl ow, adjustable
ambient heat and adjustable Input/Output currents and voltages
mean that a very wide range of measurement conditions can be
studied.

also reduces the amount of turbulence adjacent to the UUT by
restoring laminar airfl ow. Such turbulence can change the effec-
