Patent ID: 7083016

Claim:
In combination, a mobile chassis and a vehicle body interchangeable therewith, the combination comprising: a frame in the mobile chassis having a plurality of spaced-apart structural members interconnected in a manner to define a plurality of packaging spaces and an external interface; a controllable, waste-heat-producing propulsion system at least partially in at least one of the packaging spaces and controllable by wire and including a disconnectable connector in the external interface operable to disconnect the controllability of the mobile chassis by wire; and a waste heat rejection system including a first heat exchanger at least partially in at least another of the packaging spaces and a second heat exchanger in coolant flow communication with the first heat exchanger, and the waste heat rejection system including an unobstructed disconnectable fluid coupling in the external interface connectable with the vehicle body to effect fluid flow communication between the vehicle body and the heat exchangers to reject waste heat in both the mobile chassis and the vehicle body.
