5-1 . Thermal path and Airflow baffle 

    With forced convection using the axial fan , 

warm air generated by the equipment will be 

blown into the internal return opening and pass 

though the HEX, then flow out from internal 

supply opening. The air supply of the cold air 

will be used to cool down the system . 

On the opposite side, cooler air from the 

surrounding environment will be drawn in from 

the external air inlet side , and push the heat of 

the HEX out from the external air exhaust side. 

The thermal exchange path is shown in right .
