Patent ID: 7178357

Claim:
A portable cooling system comprising: a commercially available, portable ice chest having walls partially enclosing a cooler space, leaving an opening into the cooler space facing upwardly, and a ledge surrounding the opening into the cooler space; and a replacement lid dimensioned to fit on the ledge of the portable ice chest, the lid having first and second openings therethrough, each of the openings providing for the passage of air; the first opening being an intake for the passage of air only from the immediately surrounding space, into the ice chest, and the second opening being a vent for the passage of air out of the ice chest, the lid having a flat upper surface facing outwardly from the ice chest and through which the openings are formed; a motor and fan unit connected into and suspended from the replacement lid and extending from the upper surface of the lid inwardly towards the cooler space; and through the first opening for facilitating the passage of air into the cooler chest; the motor and fan unit not substantially interfering with the placement of beverages to be cooled within the chest, and means for providing electrical power to the motor; wherein the ice chest is otherwise unchanged except for the replacement lid, and whereby when ice is placed in the chest, and electrical power supplied to the motor, air forced into the chest by the fan unit is cooled when contacting the cold material, and is capable of cooling an enclosed vehicle cabin upon exiting from the cooler space through the second opening.
