COOLING DEVICE FOR VEHICLE DRIVEN BY TURBOCHARGED INTERNAL COMBUSTION ENGINE Russian patent published in 2014 - IPC F01P3/20 F01P7/14 F02B29/04 F02G5/04 

FIELD: transport.

SUBSTANCE: cooling device for vehicle driven by turbocharged internal combustion engine (2) includes inlet pipeline (8) forwarding compressed air to internal combustion engine (2), the first turbocharged air cooler (9) and the second turbocharged air cooler (10) for cooling compressed air prior to its forwarding to internal combustion engine, and energy recovery system containing pipeline circuit (32) with circulating agent, at least one heat exchanger (9, 14, 15, 34, 35) where the circulating agent should absorb heat so that it evaporates, turbine (37) where evaporated agent should expand, and at least one condenser (43) where the agent should cool to temperature of its condensation. The cooling device contains the first cooling circuit with the first cooler (20) made capable to cool circulating refrigerant, and the second cooling circuit with the second cooler (26) made capable to cool the circulating refrigerant to temperature that is lower than the temperature to which the refrigerant has been cooled in the first cooler. The cooling device contains the third cooling circuit with the third cooler (29) made capable to cool the circulating refrigerant to temperature that is lower than the temperature to which the refrigerant has been cooled in the second cooler (26). Refrigerant cooled in the third cooling circuit is used for cooling compressed air in the second cooler (10) of turbocharged air and refrigerant in condenser. Heat-absorbing system is made capable to absorb thermal energy from compressed air in the first cooler (9) of turbocharged air.

EFFECT: lower fuel consumption.
