Open Loop Wind Tunnel

The BWT-100™ is a unique, small benchtop portable wind tunnel for thermal characterization of components, boards and heat sinks. The unit is made of Plexiglas, weighs less than 4 kg (8 lbs) and produces flows up to 2 m/s (400 ft/min).

The BWT-100™ can be placed horizontally or vertically to adapt to direction-sensitive cooling systems. The test section is rear accessed and accommodates a removable test plate for mounting of the test specimens. In another version of the test plate, insulated heat slugs are provided for heat sink characterization tests. Four small DC muffin fans can be individually controlled to generate the flow inside the BWT-100™.

The test section is flush-mounted to the base of the BWT-100™ to eliminate any flow disturbances. Instrument ports are provided on the front panel of the unit for placement of temperature, velocity and pressure sensors.

Sensors to measure the flow parameters are also supplied by ATS as optional accessories.
