The Advanced Thermal Solutions BWT-104 is a research quality, open loop, bench-top 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 include honeycombs and screens to break up turbulence to provide uniform, homogeneous flow, up to 4 m/s (800 ft/min) within the test section.

The BWT-104 has 18 sensor ports allowing 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 of aluminum and Plexiglas, to provide a clear view of the test section for flow visualization. Rail guides are provided in the test section so the board (PCB) in the test position can be adjusted. An access panel is conveniently located for mounting boards. The mounting of the boards can be adjusted in three different directions (for example, spacing from the walls can be adjusted using appropriate stand-offs). 

The BWT-104 operates horizontally or vertically.

The BWT-104 is ideal for laboratory environments, weighing just 47 lbs. (21 kg). Each fan tray is equipped with three 24-volt DC fans that can be switched on and off individually through a control unit for fan failure simulation. The BWT-104 can be equipped with the ATS WTC-100 automatic controller for unattended testing. Please note, the controller is sold separately.

The BWT-104 combined with the WTC-100 can expedite and automate testing programs including component or heat sink thermal characterization, PCB thermal simulation and others that can be time-consuming. A variety of temperature, flow and pressure sensors and scanners are available (sold separately).
