OPEN LOOP WIND TUNNEL
CWT-100™
CONTROLLED OPEN LOOP WIND TUNNEL
The CWT-100™ is a research quality wind tunnel designed for PCB
and component level testing. It is used in air flow characterization
and flow visualization, thermal resistance measurements and
generation of P-Q curves.
The wind tunnel can be used to characterize different heat sink
sizes for natural and forced convection cooling. Two heat sinks
can be tested side by side to determine their thermal performance
in the same environment. Actual or simulated PCBs can be tested
for air flow distribution and pressure drop characterization.
CWT-100™ fans are tray-mounted and easily replaced with another
tray to accommodate larger or smaller fans. If other flow ranges are
required, the air velocity in the test section can be varied from 0.5 m/s
(100 ft/min) to 10 m/s (2000 ft/min) with the fan tray that is provided.
The CWT-100™ has 18 sensor ports on the front and sides of the test
section, which allows for the insertion of a variety of probes, such as
thermocouples, Pitot tubes, velocity measuring sensors, etc. It can
be operated both vertically and horizontally. The test section is
made of Plexiglas^TM for ease of flow visualization.
PCBs are mounted on a flexible railing in the test section. The
flexibility of the movable mounting plate allows users to design
and build their own modifications to suit specific needs. The mounting
plate can be adjusted in two directions using appropriate length standoffs.
The wind tunnel has honeycombs and screens to suppress turbulence and provide
uniform and near homogeneous flow at the test section. A mounted diffuser at the
exit and before the fans helps with pressure recovery to provide a smooth flow.
An optional heat slug (HP-97) will provide the thermal
performance for devices or heat sinks under test for thermal
analysis. The heat slug is mounted flush with the surface,
so there is no dimensional change to the objects under test.
