Problems solved by technology
[0006] In particular, for example, when the engine is cold started in winter, the viscosity of the engine oil increases, so that the output and efficiency of the engine decrease, thereby reducing fuel efficiency
In addition, due to the low temperature of the combustion chamber, too much exhaust gas is emitted due to incomplete combustion

A system of heat management of a vehicle may include a cooling line in which coolant cooling an engine flows therethrough; an exhaust heat retrieving apparatus for retrieving heat of exhaust gas discharged from a combustion chamber of the engine through operation fluid; a heat storage apparatus which stores heat of exhaust gas retrieved by the exhaust heat retrieving apparatus using the operationfluid and includes phase change material; a coolant heat exchanger in which heat stored in the heat storage apparatus and the coolant are heat-exchanged; a driving information detector for detecting adriving information including a temperature of the coolant and a temperature of the phase change material; and a controller for controlling the temperature of the coolant through the exhaust heat retrieving apparatus or the heat storage apparatus based on the temperature of the coolant and the temperature of the phase change material when the vehicle starts.
Description
technical field [0001] The present invention relates to a thermal management system and method for a vehicle. Background technique [0002] Typically, some of the heat generated in the engine's combustion chamber is transferred to the cylinder head, cylinder block, pistons, and the like. [0003] When the temperature of these components increases excessively, thermal deformation occurs in each component formed of a metal material, or the oil film of the inner wall of the cylinder is damaged, so that a thermal failure occurs in which lubrication between the piston and the cylinder block deteriorates. [0004] Such a thermal failure phenomenon of the engine produces abnormal combustion such as combustion defects of the engine, knocking, pre-ignition, etc., reduces thermal efficiency, and reduces output of the engine. [0005] Conversely, when the temperature of the coolant of the engine decreases excessively, the output and fuel efficiency of the engine decrease. Therefore, ...
