SYSTEM UTILITY

The WT-3100 is a unique open loop wind tunnel for thermal characterization of components,
boards and heat sinks. The unit is made of Aluminum, stainless steel and Plexi-glassTM and
produces flows up to 2000 ft/min (10 m/s) with the appropriate fans. Its unique polynomial shape
nozzle creates uniform flow in the test section. The general characteristics of the WT-3100 are
shown in the table below.

The WT-3100 test section can be accessed from the front door for mounting of the boards. A
unique internal rail guides provide mechanisms for installation of test specimen of different sizes
(e.g., PCB, heat sink). Installation of different fan trays can be provided with the system to
accommodate a broad range of velocities that maybe required for different testing applications.
The fan trays are equipped with 24 volt-DC fans, which are individually controlled to generate
the flow inside the WT-3100. Instrument ports are provided throughout the test section (on the
front and side-walls) for placement of temperature, velocity and pressure sensors. The electric
control box is provided to turn the fans on/off for the purpose of controlling the airflow inside the
tunnel. Sensors to measure the flow parameters are also supplied by Omega as optional
accessories. A wind tunnel controller can also be supplied by Omega for controlling the flow
automatically.
