Vehicle cooling system using gravity based fluid flow

Номер: US20180145381A1
Принадлежит: Faraday and Future Inc

This disclosure relates to techniques for implementing a cooling system for a vehicle heat-generating component wherein a two-phase coolant flows between a heat sink module and a heat radiator module. The heat radiator module can be mounted at a higher elevation within the vehicle than the heat sink module. High and low temperature fluid paths can fluidly couple the heat sink module and the heat radiator module. The heat sink module can be coupled to a heat-generating component. As the coolant is heated at the heat sink module by heat from the heat-generating component, it can change to a substantially gaseous phase and move, primarily by force of buoyancy, to the heat radiator module via the high temperature fluid path. As the coolant is cooled by the heat radiator module, it can change to a substantially liquid phase and move, primarily by force of gravity, to the heat sink module.
