Abstract:
1. Apparatus for circulating cooling media in a tank on a vehicle having an on board tank for the storage of a fuel gas wherein the tank is refueled under high pressure through a fuel line at a refueling depot, comprising: 1) a fluid heat absorbent media that circulates in a conduit within the tank and absorbs the heat of compression resulting from the refueling of the on board tank, 2) a conduit circuit within which the media circulates and an interconnection of the conduit to a radiator external to the tank where the heat absorbed by the media is exhausted to an environment external to the tank, and 3) a turbine interposed in the fuel line between the high pressure gas depot and the on board tank to capture the mechanical energy of gas flow within the fuel line to power the circulation of the media within the conduit.
