1-6. Thermal and Airflow
With the forced convection using the axial fan, the warm air generated by the equipment
will be blowing into the internal return opening and pass though the HEX, then flow out
from internal supply opening, the cold supply air will be used to cool down the system;
while on the opposite side, cooler air from the out environment will be drawn from the
external air inlet side and bring the heat of the HEX out from the external air exhaust
side. The thermal exchange path is shown in the figure below.
