1. 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, andmeans 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.

12. A lid for covering the top opening to a conventional, commercially available beverage cooler chest, as a replacement for a conventional lid, and for providing air conditioning to a surrounding enclosed environment, the cooler chest also intended to hold frozen material to maintain perishable products within the chest in a chilled condition, the lid comprising:
-
a housing molded to fit on the upper rim surrounding and defining the opening of the cooler chest, the housing having an upper surface, the entire area of the upper surface being flat; an air intake opening extending from the upper surface and into and through the housing designed to intake air only from the immediately surrounding space; an air exhaust opening extending through the housing, and through the upper surface; the intake and exhaust openings being formed through the flat upper surface; a motor and fan positioned within and supported from the internal transverse surface defining the air intake opening, the motor and fan extending from the upper surface of the lid, for pulling air from the surrounding environment into the cooler, the motor and fan unit designed so as to not substantially interfere with the placement of beverages to be cooled within the chest; and an electrical connector for providing electrical power to the motor for the fan; whereby when the housing is placed on the upper rim of the cooler to enclose the cooler, and frozen material is placed within the cooler, air can be circulated from the surrounding environment by the fan, through the air intake opening and into the cooler chest, cooling the air by contacting the frozen material inside the cooler, as the frozen material within the cooler chest melts, the cooled air being passed out through the air exhaust opening into the surrounding enclosed environment. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
