Abstract
A portable air-cooling device includes an insulated base for holding a coolant and a lid formed to cover the insulated base. The lid includes a heat exchange assembly for cooling an airflow and one or more openings for exhausting the airflow that has been cooled in the heat exchange assembly. Flexible, rotatable ducts are joined to each of the one or more openings of the lid and are positionable by a user to direct the airflow that has been cooled.
Claims17
A portable air-cooling device, comprising:
- an insulated base having an interior compartment for holding a liquid coolant;
- a lid formed to cover the insulated base, wherein the lid includes:
- a heat exchanger extending across an air discharge passageway extending through the lid, the heat exchanger including a coolant conduit with a plurality of heat transfer fins projecting from the coolant conduit;
- a pump flow connected to the coolant conduit for pumping the liquid coolant from the interior compartment of the insulated base through the coolant conduit and back to the interior compartment of the insulated base;
- and
- one or more air discharge openings formed in the lid in communication with the air discharge passageway;
- one or more discharge conduits, each of the one or more discharge conduits rotatably coupled to the lid around one of the one or more air discharge openings of the lid, wherein the one or more discharge conduits are flexible and extendable by a user;
- at least one fan extending across the air discharge passageway for drawing a stream of air through an air intake passageway in the lid and through the heat exchanger and out the one or more air discharge openings and through the one or more discharge conduits which are positionable by the user to direct the stream of air;
- and
- a plenum chamber including a covering structure that is selectively positionable in an open position and in a closed position, wherein when the covering structure is in the open position, at least a portion of the stream of air from the air intake passageway in the lid is directed to the interior compartment of the insulated base.
