Vertical Wind Tunnel
Murata Power Solutions employs a custom-designed enclosed
vertical wind tunnel, infrared video camera system and test
instrumentation for accurate airow and heat dissipation
analysis of power products. The system includes a precision low
ow-rate anemometer, variable speed fan, power supply input
and load controls, temperature gauges and adjustable heating
element.
The IR camera can watch thermal characteristics of the Unit
Under Test (UUT) with both dynamic loads and static steady-
state conditions. A special optical port is used which is transpar-
ent to infrared wavelengths. The computer les from the IR
camera can be studied for later analysis.
Both through-hole and surface mount converters are soldered
down to a host carrier board for realistic heat absorption and
spreading. Both longitudinal and transverse airow studies are
possible by rotation of this carrier board since there are often
signicant differences in the heat dissipation in the two airow
directions. The combination of both adjustable airow, adjustable
ambient heat and adjustable Input/Output currents and voltages
mean that a very wide range of measurement conditions can be
studied.
The airow collimator mixes the heat from the heating ele-
ment to make uniform temperature distribution. The collimator
also reduces the amount of turbulence adjacent to the UUT by
restoring laminar airow. Such turbulence can change the effec-
tive heat transfer characteristics and give false readings. Excess
turbulence removes more heat from some surfaces and less heat
from others, possibly causing uneven overheating.
Both sides of the UUT are studied since there are different thermal gradi-
ents on each side. The adjustable heating element and fan, built-in tempera-
ture gauges and no-contact IR camera mean that power supplies are tested in
real-world conditions.
