An air cooling device includes a thermally insulated container being packed with encapsulated refrigerant and adapted to pass incoming air for cooling. The air cooling device has a housing adapted to accommodate the thermally insulated container and force the incoming air to flow inside the refrigerant-packed container against gravity to ensure a prolonged air cooling period. The encapsulated refrigerant is configured as a plurality of compacted frozen glycol balls serving as primary source of cooling for the incoming air. Air pockets are formed between the frozen glycol balls that serve as secondary source of cooling for the incoming air.
