Bench Top Wind Tunnel Demonstrates ATS Innovations in Thermal Management Instrumentation

Jul 28, 2011

The BWT-104WA™ is a research quality, open loop, benchtop wind tunnel for thermal characterization of components, circuit boards and cooling devices.

The BWT-104WA™ is a research quality, open loop, benchtop wind tunnel for thermal characterization of components, circuit boards and cooling devices.

Advanced Thermal Solutions, Inc, (ATS), continues its innovations in electronics thermal management with the BWT-104 Bench Top Wind Tunnel. The BWT-104 is a research quality, open loop wind tunnel for thermally characterizing components, circuit boards and cooling devices such as heat sinks, heat exchangers and cold plates.

The wind tunnel’s polynomial shape and internal flow management system includes honeycombs and screens to breakup turbulence and provides uniform, homogeneous flow, up to 4 m/s (800 ft/min) within its test area. The BWT-104 has 12 ports which allow a variety of probes, such as thermocouples, Pitot tubes, and temperature and velocity sensors, including the small ATS Candlestick Sensor, to be inserted throughout the test section.

The BWT-104 wind tunnel is made from aluminum and Plexiglas® and, provides a clear view of the test section for flow visualization. An access panel is conveniently located for mounting boards and, optional internal rail guides allow for simple installation of PCBs and heat sinks. The instrument weighs only 14.5 kilograms (32 lbs.) and 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. It is also available with the optional WTC-100 Wind Tunnel Controller, which helps automate thermal characterization, as an optional accessory. ATS also carries a full line of temperature, flow and pressure sensors and scanners that are designed for use with the BWT-104. The laboratory wind tunnel represents ATS’s continued dedication to offer world class thermal engineering solutions including the superGRIP heat sink clip and iQ-200 Thermal Analysis system.


Advanced Thermal Solutions, Inc (ATS) is a leading-edge engineering/manufacturing company focused on innovative solutions for the thermal management of electronics. Founded in 1989 as a consulting company, ATS has evolved to a complete thermal solutions provider and is world renown for its portfolio of more than 450 high- and ultra performance heat sinks, research-quality test equipment, and leading-edge R&D. In the interval of three years, ATS has established its own manufacturing center in the U.S., developed strategic partnerships with Asian manufacturers and opened ATS-Europe, its sales and engineering office in Holland. As ATS has significantly increased its customer base, its product offerings have also expanded to include Advanced Fan Trays, Liquid Cooling Systems, Advanced Cooling Systems and Next-Generation Thermal Test Instruments.
