Circulating fluid regulating device for motor vehicle, has heat storage unit cooling coolant liquid to reduce temperature of heat engine and re-circulated gases, during one period and heating liquid during another period

摘要

The device has a coolant/lubrication oil exchanger (14) and a coolant/re-circulated exhaust gas exchanger (16) that are connected to a coolant circuit (10). A heat storage unit (18) cools a coolant liquid to reduce the temperature of a heat engine (12) e.g. diesel engine, and re-circulated gases, during one period. The unit (18) heats the liquid during another period, when the unit (18) is in heating mode. An independent claim is also included for a process for regulating heat of fluids implemented by a fluid heat regulating device.
