Wind Tunnel Aids Thermal Management

Sept. 5, 2012
Thermal studies just got easier, thanks to a closed-loop wind tunnel capable of characterizing a device under test (DUT) at temperatures to +85°C.

Thermal studies just got easier, thanks to a closed-loop wind tunnel capable of characterizing a device under test (DUT) at temperatures to +85°C. The model CLWT-115 wind tunnel from Advanced Thermal Solutions can generate air flows to 5 m/s (1000 ft/minute), or as much as 50 m/s (10,000 ft/minute) using optional orifice plates. Its clear Lexan test section offers a continuous view of a DUT—such as a printed-circuit board (PCB), heat sink, or electronic component—and allows operators to perform flow visualization studies using smoke or vapor.

Unlike an open-loop wind tunnel, the closed-loop model CLWT-115 recirculates internal air, allowing the system’s heater to quickly warm the air to a specific temperature. The wind tunnel features a test section measuring 30.5 x 10.2 x 4.55 in. (77.6 x 26.0 x 11.6 cm) that can be accessed from the top or sides for mounting and repositioning DUTs. Internal rail guides provide an easy system for installing specimens of different sizes. A complete CLWT-155 wind tunnel fits on most lab benches and is powered from standard AC outlets.
