The unit is made of Aluminum, sheet metal and LEXAN™ and produces flows up to 1400 ft/min (7 m/s) and temperature up to 85°C. The CLWT-067-PCIe™ uses the proven technology of the CLWT-067 and adds a new m test section specially designed for the thermal testing and characterization of either full or half-height standard PCIe cards.

Key to Numbers in Figure 1 PCle riser card slots (riser cards not included with the wind tunnel) and test section (test section is included with the wind tunnel) Instrument ports Blower Diffuser section Nozzle section Test section top cover panel Stands Heater section Heater power plug The CLWT-067-PCIe™ wind tunnel produces air flows up to 7 m/s (1,400 ft/min). With customization, it can generate flows up to 50 m/s (10,000 ft/min) using orifice plates (available optionally). The clear LEXAN™ test section lets the user view the test specimen and allows for ease of flow visualization. Unlike open loop wind tunnels, the CLWT-067-PCIe™ 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 many electric systems such as components and power supplies. The precise controls of air temperature and velocity along with the board temperature range of the CLWT-067-PCIe™ wind tunnel makes it a versatile test instrument for a variety of applications. The complete wind tunnel fits on most lab benches and is powered from the CLWTC-1000™ and the stageCONTROL™ software (included with the wind tunnel purchase). The CLWTC-1000 requires 220 VAC at 20 Amps. The wind tunnel test section allows for 5 Sensor ports to provide access for sensors, pitot tubes or thermocouples to measure air velocity, pressure, humidity and temperature (separate hot wire anemometer or other instrument required) Product Specifications Overall Dimensions (LxWxH) 143.1 x 49.3 x 67.7 cm (56.37 x 19.4 x 26.6") Test Section Dimensions (L x W x H) 43.1 x 25.0 x 8.9 (inside wall to wall) cm (16.9 x 9.8 x 3.5") Number of Instrument Ports 5 Flow Range 0 to 7 m/s (1400 ft/min) Temperature Range Ambient to 85°C (ambient to 185°F) Weight 70.7 kg (156 lbs.)
