Patent attributes
In one or more embodiments, a disclosed method for cooling a vehicle involves routing, by a bypass line, boil-off of a cryogenic fuel of the vehicle past a cold plate to cool a subsystem mounted proximate the cold plate. The method further involves purging the boil-off in a direction away from the vehicle, after the boil-off passes the cold plate. In one or more embodiments, the cryogenic fuel involves liquid hydrogen (LH2), liquid oxygen (LO2), and/or liquid methane (LCH4). In at least one embodiment, the boil-off of the cryogenic fuel involves gaseous hydrogen (GH2), gaseous oxygen (GO2), and/or gaseous methane (GCH4). The vehicle is a space vehicle, an airborne vehicle, a terrestrial vehicle, or a marine vehicle. In at least one embodiment, the vehicle is a fuel cell vehicle (FCV).
