General Testing:
1.
Release the clamps on front door to have access to the test section.
2.
Mount your specimen (e.g., component, PCB or heat sink) in the test section.
3.
Clamp the door back on the WT-3100.
4.
Place flow measurement instrument in the instrument port.
5.
Connect the fan cable to the controller box (5).
6.
Connect the fan controller box (5) to a DC power supply or wind tunnel controller.
Important Note:
Voltage to the fans cannot exceed 26 Volts-DC.
7.
Adjust voltage until desired flow rate is attained.
Component and Heat Sink Testing:
1.
Release the clamps on front door to have access to the test section.
2.
Mount your component(s) in the test section.
3.
Clamp the door back on the WT-3100.
4.
Connect the fans to a variable DC power supply. Voltage to the fans cannot exceed 26
Volts-DC. Adjust voltage until desired flow level is attained.
5.
Insert the velocity and temperature probes into the instrument ports provisioned in
upstream of the test section.
6.
Turn on the power supplies and start the experiment.
Note: If the wind tunnel is provided with a heat slug, please apply a coating of thermal grease to
the cylindrical heater and place it inside the hole in the Delrin housing behind the test plate.
Measure the resistance of the heater with a Multimeter. Connect the the heater to an external
power supply and adjust the voltage for the desired power dissipation. Please make sure that
the temperature of the heater does not become excessive, otherwise it will damage the Delrin
hosing. Depending on the heat sink that is mounted on the slug, always start with a low Watt to
get a feeling for the temperature.
