OPEN LOOP WIND TUNNEL CWT Series FEATURES: » Component Temperature Testing Evaluate the effects of airflow on components, temperature and PCB response and reliability CONTROLLED OPEN LOOP WIND TUNNEL » H eat Sink Characterization These research quality wind tunnels are designed for PCB and component level testing. They are used in air flow characterization and flow visualization, thermal resistance measurements and generation of P-Q curves. Characterize a variety of heat sink sizes for natural and forced convection cooling » Sensor Calibration Fans are tray-mounted and easily replaced with another tray to accommodate larger or smaller fans. If other flow ranges are required, the air velocity in the test section can be varied from 0 m/s (0 ft/min) to 10 m/s (2000 ft/min) with the fan tray that is provided. (see chart below) Uniform velocity profile at the test section allows accurate calibration of sensors » H eat Sink Comparison There are sensor ports on the front and sides of the test section, which allows for the insertion of a variety of probes, such as thermocouples, Pitot tubes, velocity measuring sensors, etc. The test section is made of PlexiglasTM for ease of flow visualization. Test two heat sinks side by side and compare their thermal performance in the same environment » P ressure Drop Testing Measure pressure drop across components or PCB for a given flow PCBs are mounted on a flexible railing in the test section. The flexibility of the movable mounting plate allows users to design and build their own modifications to suit specific needs. The mounting plate can be adjusted in two directions using appropriate length standoffs. » Multiple PCB Testing Test actual or simulated PCBs for thermal and flow distribution The wind tunnel has honeycombs and screens to suppress turbulence and provide uniform and near homogeneous flow at the test section. A mounted diffuser at the exit and before the fans helps with pressure recovery to provide a smooth flow. » Flow Visualization * Power supply not included. » Variable Speed Observe air flow distribution in the tunnel by smoke or buoyant bubbles through the all PlexiglasTM test section Product Length Width Depth Weight Test Domain (L x W x D) Sensor Ports Velocity Range Fans CWT-100 197.6 cm (77.8") 81.3 cm (32") 68.6 cm (27") 51.7 kg (114 lbs) 61 x 40.6 x 8.3 cm (24 x 16 x 3.3") 18 0 to 10 m/s (0 to 2000 fpm) Four 24 VDC CWT-104 198 cm (78") 107 cm (42") 86 cm (34") 74 kg (164 lbs) 61 x 61 x 10 cm (24 x 24 x 4") 18 0 to 9 m/s (0 to 1800 fpm) Five 24 VDC CWT-105 198 cm (78") 107 cm (42") 86 cm (34") 75 kg (165 lbs) 61 x 61 x 12.7 cm (24 x 24 x 5") 18 0 to 7 m/s (0 to 1400 fpm) Five 24 VDC CWT-106 195.6 cm (76.9") 101.6 cm (40") 84.8 cm (33.4") 72 kg (159 lbs) 61 x 61 x 15.2 cm (24 x 24 x 6") 18 0 to 6 m/s (0 to 1200 fpm) Five 24 VDC CWT-107 197.7 cm (77.84") 101.6 cm (40") 77.2 cm (30.4") 70 kg (155 lbs) 61 x 61 x 17.8 cm (24 x 24 x 7") 18 0 to 5.5 m/s (0 to 1100 fpm) Five 24 VDC CWT-108 195 cm (77") 101 cm (40") 83 cm (33") 88 kg (193 lbs) 61 x 61 x 20.3 cm (24 x 24 x 8") 18 0 to 5.5 m/s (0 to 1100 fpm) Five 24 VDC CWT-109 203.2 cm (80") 107 cm (42") 89 cm (35") 88.4 kg (195 lbs) 61 x 61 x 22.9 cm (24 x 24 x 9") 18 0 to 5 m/s (0 to 1000 fpm) Five 24 VDC CWT-110 213.4 cm (84") 107 cm (42") 100 cm (40") 90 kg (198 lbs) 61 x 61 x 25.4 cm (24 x 24 x 10") 18 0 to 4.5 m/s (0 to 900 fpm) Five 24 VDC CWT-112 223.5 cm (88") 107 cm (42") 114 cm (45") 91 kg (201 lbs) 61 x 61 x 30.5 cm (24 x 24 x 12") 18 0 to 3.2 m/s (0 to 750 fpm) Five 24 VDC CWT-125 238.8 cm (94") 107 cm (42") 152 cm (60") 95 kg (210 lbs) 61 x 61 x 63.5 cm (24 x 24 x 25") 18 0 to 2 m/s (0 to 400 fpm) Six 24 VDC Change flow rates by controlling the fan RPM » Quick Access Quickly change the test specimen through the front access test section » Sensor Ports Measure pressure, velocity and temperature through the sensor ports » Orientation Wind tunnel can be operated horizontally or vertically RECOMMENDED ACCESSORIES: WTC-100™ Wind Tunnel Controller For further technical information, please contact Advanced Thermal Solutions, Inc. at 1-781-769-2800 or www.qats.com 89-27 ACCESS ROAD, NORWOOD, MA 02062 USA | T: 781.769. 2800 F: 781.769.9979 | WWW.QATS.COM CLWTC-1000 Wind Tunnel Controller ATVS-NxT™ Hot Wire Anemometer HP-97TM High Power Component Simulator R2_0813
