OPEN LOOP WIND TUNNEL

FEATURES:

Test actual or simulated PCBs

for thermal and flow distribution

Observe air flow distribution

in the tunnel by smoke or

buoyant bubbles through the

High quality flow with very low

turbulence intensity

Characterize a variety of heat

sink sizes for natural and forced

convection cooling

Test two heat sinks side by

side and compare their thermal

performance in the same

environment

Utilize for individual or

multiple component testing

Change air flow rates by

controlling the fan RPM

Quickly change the test specimen

through the test section cover

Measure pressure, velocity

and temperature through

the sensor ports

Uniform velocity profile at the

testing section allows accurate

calibration of sensors

APPLICATIONS:

CUSTOMIZED RESEARCH QUALITY WIND TUNNEL

The

CWT-106™ is a research quality wind tunnel designed

for multiple PCB and component level testing. It is used in air

flow characterization and flow visualization, thermal resistance

measurements and generation of P-Q curves. The large test

section (24 x 24 x 6") is designed to accommodate multiple

PCBs as seen in a typical ATCA chassis.

The wind tunnel can also be used to characterize different

heat sink sizes for natural and forced convection cooling.

Multiple heat sinks can be tested side by side to determine

their thermal performance in the same environment.

The

CWT-106™ produces uniform air flows of up to 6 m/s

(1200 ft/min). Air is drawn into the tunnel with up to five variable

DC fans mounted at the exhaust section of the tunnel. These

fans are mounted on a tray and can be easily replaced with

another tray to accommodate larger or smaller fans,

should different air flow ranges be required.

An internal flow management system, with honeycombs and screens, breaks up

turbulence and provides uniform and homogeneous flow in the test section.

The

CWT-106™ can be operated both vertically and horizontally and features a

Plexiglas™ test section for ease of flow visualization.

The

CWT-106™ includes 18 sensor ports in front and on the sides of the test section

for the insertion of a variety of probes, such as thermocouples, Pitot tubes, velocity

measuring sensors, etc.

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.
