PRLog - June 16, 2011 - NORWOOD, Mass. -- The CLWT-067 is a research-quality, closed loop, benchtop wind tunnel that provides a convenient, accurate system for thermally characterizing PCBs and individual components at controlled temperatures from ambient to 85°C.
CLWT-067 Closed Loop Wind Tunnel from ATS
The CLWT-067 wind tunnel produces air flows up to 7 m/s (1378 ft/min) and can be customized to generate flows up to 50 m/s (10,000 ft/min) using orifice plates (available optionally). Users are able to view the test specimen through the clear Lexan test section, providing the opportunity for flow visualization. The complete wind tunnel fits on most lab benches and is powered from standard AC outlets. It has a smaller footprint than traditional, closed loop wind tunnels or environmental test chambers.
The wind tunnel’s test section can be easily accessed from the top door for mounting and repositioning of boards, components and sensors. Internal rail guides provide a quick mechanism to change and install different test specimens, such as PCBs and heat sinks. Six instrument ports, provided in the side walls of the test section, can be placed with temperature and velocity sensors such as thermocouples, pitot tubes and hot-wire anemometers allowing for precise pressure, velocity, and temperature measurement.
Unlike open loop wind tunnels, the CLWT-067 re-circulates 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 allow for an accurate calibration of air and temperature sensors. The CLWT-067 can characterize a variety of heat sink sizes for natural and forced convection cooling and evaluate the effects of elevated temperatures on component and PCB response and reliability. This versatile wind tunnel can test actual or simulated PCBs for thermal and flow distribution, and test individual or multiple components.
Also available for purchase, the CLWTC-1000 is a custom wind tunnel controller specifically designed for the CLWT-067 to automatically control the air flow and temperature through the test chamber.
