Abstract
The invention concerns a motor vehicle cooling and depolluting device designed for conditioning said vehicle passenger compartment and for cooling its cylinder block (22). The elements of the device are connected through a main tube (25) containing an antifreeze liquid. The device also comprises a temperature and pressure control valve (17), to maintain a constant pressure in the cylinder block (22) and located downstream of the cylinder block (22), a ventilated water-air exchanger (6) enabling a motor vehicle passenger compartment to be cooled, a ventilated water-air exchanger (1) enabling a motor vehicle engine compartment to be cooled, at least a cold water tank (3) for cooling upon start-up of the motor vehicle and located between the ventilated water-air exchanger (6) and the evaporator (24) and a solenoid valve (9) for controlling the temperature inside the motor vehicle passenger compartment and located downstream of the ventilated water-air exchanger (6). A water-fume exchanger (21), located downstream of a water-fume exchanger (20), serves to depollute the exhaust gases of an engine (18) by cooling said exhaust gases and condensing its hydrocarbon residues as well as by tr…
