Compact wind tunnel enables thermal, airflow testing on PCBs, components

NORWOOD, Mass., 14 March 2007. Advanced Thermal Solutions Inc. (ATS) has introduced the BWT-104, a research-quality, open-loop, benchtop wind tunnel for thermal characterization of components, circuit boards, and cooling devices, such as heat sinks, heat exchangers, and cold plates. The polynomial shape and internal flow management system includes honeycombs and screens to break up turbulence and provides uniform, homogeneous flow, up to 6 m/s (1200 ft/min) within the test section.

The BWT-104 has 12 ports which allow a variety of probes, such as thermocouples, Pitot tubes, and temperature and velocity sensors, among others, to be inserted throughout the test section.

The wind tunnel is made from aluminum and Plexiglas and provides a clear view of the test section for flow visualization. An access panel is located for mounting boards, and optional internal rail guides allow for simple installation of PCBs and heat sinks.

The BWT-104 is 36x17.25x17.25 inches and weighs 32 pounds. It has the ability to operate on any axis, making it ideal for laboratory environments.

Each BWT-104 fan tray is equipped with three 24-volt DC fans, which can be individually switched on and off, with an included control unit to generate airflow.
