Test Scenario 4: Quad Core EPU-3311-EDP + HDW-408 Heat Pipe Block
This data is supplied as a reference point for custom heat pipe solutions.
Table 20: Heat Pipe Additional Configuration Details
Passive Solution Configuration
HDW-408 Heat Pipe Block mounted to the EPU-3311 heat plate
with:
Three 4 mm x 225 mm copper / water heat pipes
The EPU-3311 is inside an environmental chamber at the
noted temperatures
Thermal solution at far end of heat pipes:
HDW-408 heat pipe block attached to a HDW-406 heat sink
The thermal solution is outside of the environmental chamber
in free-air at an ambient temperature of 25 ºC
Active Configuration
Same as above with an added HDW-411 fan on the HDW-406
heat sink
