Abstract: A two-phase versatile evaporative cooling heat exchange apparatus 2 for use to produce cool air for homes, factories or for use in vehicles both stationary and moving. The vessel 4 contains the components needed so ambient air 6 is drawn or forced into the evaporative pad 32 to begin the cooling process. The evaporative pad 32 is wetted by thermal liquid 26 being distributed by pump 20 for the first phase cooling 8. The evaporation process uses a portion of the thermal liquid 26 with the remaining, now cooled, excess thermal liquid 36 being returned to the base of vessel 8. The cooled thermal liquid 26 is pumped through the heat exchanger 40 for the second phase cooling 10. The cooled air 12 is delivered into the occupant space 18.
