The WT-3100 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 thermal flow distribution and pressure
drop characterization.
Fans are tray-mounted and easily replaced with
another tray to accommodate larger or smaller fans.
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).
The WT-3100 has 18 sensor ports on the front and
sides of the test section, which allows inserting 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® for ease of flow visualization.
The mounting plate can be adjusted in 2 directions
using appropriate length standoffs. The flexibility of the
movable mounting plate allows users to design and
build their own modifications to suit specific needs.
The WT-3100 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. Rail
guides are provided so the unit position can
be adjusted.
A switch box is provided with the unit so some fans can
be turned off for lowest possible air flow. An optional
heat slug will provide the heat 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. Sensors
to measure the flow parameters are also available by
Omega as optional accessories.
