Both sides of the UUT are studied since there are different thermal
from others, possibly causing uneven overheating.

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.
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 fi 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 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.
The airfl ow collimator mixes the heat from the heating element
to make uniform temperature distribution. The collimator also
reduces the amount of turbulence adjacent to the UUT by restor-
ing laminar airfl ow. Such turbulence can change the effective
heat transfer characteristics and give false readings. Excess
