OPEN LOOP WIND TUNNEL

FEATURES:

Test actual or simulated PCBs for

thermal and air flow distribution

Characterize a variety of heat

sink sizes for natural and forced

convection cooling

Uniform velocity profile at the

testing section allows accurate

calibration of sensors

Multiple PCBs testing simulated

up to six PCBs in parallel

An ideal test vehicle for

component characterization

Observe air flow distribution

in the tunnel by smoke or

buoyant bubbles through the

Change air flow rates by

controlling the fan RPM

Quickly change the test

specimen through the test

section cover and side access

Measure pressure, velocity

and temperature through

the sensor ports

APPLICATIONS:

TEST MULTIPLE PCBs IN WIND TUNNEL

A unique, fully controllable wind tunnel for thermal

and air flow testing of multiple PCBs. The test

chamber has a 2-D converging nozzle with a multi-point

measurement area for sensor placement upstream of the

test section. The test section is equipped with card guides

to allow insertion of actual or simulated PCBs from the

side panel.

The wind tunnel is designed to test up to six PCBs side

by side as seen in a electronic cabinet. The wind tunnel

can also be used for standard thermal characterization

such as component, PCBs, cold plates, etc.

The chamber can accommodate up to 6 PCBs with

13 mm (0.5") card-to-card spacing or 3 PCBs with

25 mm (1") card-to-card spacing.

The test section is made of clear polycarbonate

material to accommodate smoke flow visualization.

The chamber has its own stand for placement

of instruments. The

CWT-PCB™ is placed on

castors for ease of transportation.

The

CWT-PCB™ can be fitted with different

fan trays to accommodate a broad air flow

range. Heating elements can be added for

elevated air temperature testing.

* Power supply not included.
