The CLWT-115 research quality, closed loop wind tunnel from ATS provides a convenient, accurate system for thermally characterizing PCBs and individual components at controlled temperatures from ambient to 85°C.
Advanced Thermal Solutions, ATS has introduced the CLWT-115 wind tunnel which allows engineers to evaluate the effects of elevated temperatures on component and PCB response and reliability. The new research quality, closed loop wind tunnel provides a convenient, accurate system for thermally characterizing PCBs and individual components at controlled temperatures from ambient to 85°C.
The CLWT-115 wind tunnel produces high quality, low turbulence air flows of up to 5 m/s (1000 ft/min). When customized, it can generate flows up to 50 m/s (10,000 ft/min) using optionally available orifice plates. The clear Lexan test section lets the user view the test specimen and allows for flow visualization.
Unlike open loop wind tunnels, the CLWT-115 recirculates internal air. This allows the system heater to quickly warm the air to a specific temperature. 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 heat sink performance and for calibrating air and temperature sensors.
The wind tunnel’s test section can be accessed from the top door or sides for mounting and repositioning of boards, components and sensors. Internal rail guides provide an easy mechanism to install test specimens of different sizes (e.g., PCB, heat sink).
Instrument ports (6) are provided in the side walls of the test section for placing temperature and velocity sensors such as thermocouples, Pitot tubes and hotwire anemometers.
