Abstract
Present embodiments relate to an active insulated container which may be used in a vehicle. More specifically, but without limitation, present embodiments relate to active insulated containers which may be mounted in a vehicle and which creates a positive pressure upon entry of water into one or more ducts to preclude entrance of water into a thermal engine enclosure housing the thermal engine, even when mounted at a lower elevation of the vehicle.
Claims11
An active insulated container, comprising:
- a housing comprising a base and one or more walls extending upwardly from said base;
- upper ends of said one or more walls defining an opening for access to an interior of said housing;
- a lid disposed at said opening, said lid being movable to allow or limit access to said interior;
- a thermal engine comprising a compressor, a condenser, an evaporator, and at least one air mover, said thermal engine disposed in a thermal engine enclosure;
- a first duct and a second duct, said first duct configured to allow airflow from outside said housing to said thermal engine, and said second duct configured to allow said airflow to exhaust from said thermal engine;
- an inlet of said first duct and an outlet of said second duct being disposed at a lower elevation of said housing, wherein air within said first and second ducts and said thermal engine enclosure is compressed when water rises through said inlet and said outlet of said first and second ducts.
3 more elements
A vehicle, comprising:
- a fording line of the vehicle;
- an active insulated container configured to be installed in said vehicle at a level below said fording line;
- said active insulated container having:
- a housing comprising a base and a plurality of walls extending from said base, said plurality of walls defined by an exterior wall and a liner, and forming a thermal engine enclosure therebetween;
- upper ends of said plurality of walls defining an opening for access to an interior of said housing;
- a lid disposed at said opening, which opens and closes to allow or limit access to said interior;
- a thermal engine including a compressor, a condenser, an evaporator, and at least one air mover, said thermal engine disposed in said thermal engine enclosure;
- a first duct and a second duct, said first duct configured to allow airflow from outside said housing to said thermal engine enclosure, and said second duct configured to allow said airflow to exhaust from said thermal engine enclosure;
- an inlet of said first duct and an outlet of said second duct being disposed at a lower elevation of said housing, and each of said first duct and said second duct extending upwardly turning and extending downwardly such that air pressure in said thermal engine enclosure is higher than the pressure of incoming water in said first and second ducts, preventing water from entering through said first and second ducts.
