Cooling circuit for motor vehicle drive system has heat exchanger arranged immediately after radiator in flow direction so that coolant at lowest temperature is fed to heat exchanger

摘要

The cooling circuit has at least one radiator (6) connected to the vehicle engine (1), a thermostat (4) and a bypass valve (5) in the return line (3), a heat exchanger (17) and circulating pump (2) in the feed line (8) and a bypass line (7) coupled to the thermostat for bypassing the radiator. The heat exchanger is arranged immediately after the radiator in the flow direction so that the coolant at the lowest temp. is fed to the heat exchanger .
