Abstract (en)
The present invention relates to a heat recovery device particularly conceived for an internal combustion engine, and in particular for a vehicle including said internal combustion engine. The heat recovery device is based on a Rankine cycle in which the high-pressure stage has been modified. The invention is characterized by the use of a tank in the high-pressure region of the Rankine cycle for storing the fluid before entering the turbine or expander maintaining said fluid in the liquid phase so as to drastically reduce the specific volume, and an expansion valve arranged between the tank and the inlet of the turbine or expander for causing the liquid-to-vapor phase change of the fluid right at the inlet, which prevents that the high specific volume in the vapor phase leads to large-sized devices.
