Patent ID: 8555640

Claim:
A heat exchange unit for a vehicle comprising: a core unit including an accumulator and having a fluid therein and configured to convert the fluid to a body of vapor having a pressure; a first energy generation module having a first turbine optimized for operation at a first range of vapor pressures connected with the core unit via a first connection for passing a first portion of the body of vapor from the core unit to the first energy generation module, the first energy generation module configured to use the first portion of the body of vapor to generate energy for a first electrical device; and a second energy generation module having a second turbine optimized for operation at a second range of vapor pressures connected with the core unit via a second connection for passing a second portion of the body of vapor from the core unit to the second energy generation module, the second energy generation module configured to use the second portion of the body of vapor to generate energy for a second electrical device.
