Wind tunnel for high-temperature testing

17 October 2012 Manufacturing / Production Technology, Hardware & Services

The new CLWT-115 research-quality, closed loop wind tunnel from Advanced Thermal Solutions provides an accurate and convenient system for thermally characterising printed circuit boards, heatsinks and components at controlled temperatures from ambient to 85°C.

The machine produces air flows up to 5 m/s; using optional orifice plates it can generate flows up to 50 m/s. Its clear Lexan test section provides a continuous view of the test specimens, as well as flow visualisation studies, eg, using smoke or vapour.

The testing of boards and components in hot air is a requirement in some NEBS and other standards. The precise controls and temperature range of the CLWT-115 wind tunnel allows its use for testing heatsink performance and for calibrating air and temperature sensors.

Unlike open loop wind tunnels, the CLWT-115 recirculates internal air, allowing the system heater to quickly warm the air to a specific temperature. It provides a generous test section measuring 77,6 x 26 x 11,6 cm, which can be accessed from the top or sides for mounting and repositioning boards, components and sensors.

Internal rail guides provide an easy system to install test specimens of different sizes. Six instrument ports in the side walls of the test section are for temperature and velocity sensors such as thermocouples, Pitot tubes and hotwire anemometers.

A complete CLWT-155 wind tunnel fits on most lab benches and is ­powered from standard AC outlets.
