Thermal control device for fluids circulating in a vehicle with heat engine and method implemented by this device

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.
