Circuit arrangement for cooling a motor vehicle with an air conditioning system and heat exchanger for such a circulation arrangement

摘要

The arrangement (1) has a vehicle component cooling circuit (8) branched in a flow direction of coolant (km) e.g. water and methanol, to an expansion valve (6) of an air conditioning apparatus circuit (2). Individual vehicle components e.g. cooling circuit of an internal combustion engine, in heat exchangers (7.1-7.x) are thermally coupled to the air conditioning circuit. The coolant circulates the entire circuit arrangement until a phase transition undergoes in the heat exchangers. A compressor (4) is arranged in the air conditioning apparatus circuit. The vehicle components are designed as an intercooler, exhaust gas recirculation, engine oil circuit, transmission oil circuit, lubricating oil circuit, hydraulic oil circuit and/or electrical drive components.
