The CWT-100 is a research quality wind tunnel designed for PCB and component level testing. It can be used for flow characterization, flow visualization and thermal resistance measurements.
The wind tunnels can be used to characterize various heat sink sizes for natural and forced convection cooling. Two heat sinks can be comparison tested side by side to determine their thermal performance in the same environment. Actual or simulated PCBs can be tested for thermal and flow distribution.
Fans are tray-mounted and easily replaced with another tray to accommodate larger or smaller fans. The air velocity in the test section through the system can be varied from 0.5 m/s (100 ft/min) to 10 m/s (2000 ft/min).
The wind tunnel has honeycombs and screens to break up turbulence and provide uniform and homogeneous flow at the test section. A mounted diffuser at the exit and before the fans helps pressure recovery.
An optional heat slug will heat up devices or heat sinks under test for thermal analysis. The slug is mounted flush with the surface so there is no dimensional change to the objects under test.
