Advanced Thermal Solutions CLWT-067 – Closed Loop Wind Tunnel

• Benchtop closed-loop wind tunnel for elevated temperature testing of boards and components
• Air flows from 1 to 7 m/s (200 to 1,400 ft/min)
• Temperature range: Ambient to 85°C (Ambient to 185°F)
• Evaluate the effects of elevated temperatures on components and power supplies at different velocities
• Aerodynamic and pressure drop measurement

The Advanced Thermal Solutions CLWT-067 is a research-quality closed-loop wind tunnel that provides a convenient, accurate system for thermally characterizing PCBs and individual components at controlled temperatures from ambient to 85°C. Its test section dimensions are 43.1 x 25.0 x 8.9 (L x W x H). The CLWT-067 wind tunnel produces air flows up to 7 m/s (1,400 ft/min). The clear Lexan test section allows the user to view the test specimen and allows for flow visualization.

Unlike open-loop wind tunnels, the CLWT-067 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-067 wind tunnel allow its use for testing heat sink performance and for calibrating air and temperature sensors. Please note, sensors are sold separately.

The complete wind tunnel fits on most lab benches and is powered by the CLWTC-1000 (sold separately). The CLWTC-1000 requires 220VAC at 20 amps. The CLWT-067 has a smaller footprint than traditional, closed-loop wind tunnels or environmental test chambers.

The wind tunnel’s test section can be accessed from the top door for mounting and repositioning of boards, components and sensors. Optional internal rail guides (sold separately) 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 (sold separately).
