Vehicle Thermal Management System having Integrated Thermal Management Valve and Coolant Circuit Control Method of Vehicle Thermal Management System Thereof

摘要

The vehicle thermal management system 100 of the present invention selectively passes through the heater core 200, the radiator 300, the EGR cooler 500, the oil warmer 600, the ATF warmer 700, and the EHRS 800. The four-port layout of the ITM(1) by including a plurality of coolant circulation/distribution systems (100-1,100-2,100-3) in which the engine coolant flow circulating 110) is formed by linking the ITM(1) and the SSV(40). In addition to the cooling water required to improve the EGR condensate problem with the SSV (400), a relatively large flow of cooling water is added to the EGR cooler (500) to reduce the time of use of EGR, which is advantageous for improving fuel economy, while cooling water required to improve the heating warm-up performance. In addition to supplying to the exhaust heat recovery device 800 and the heater core 200, a feature of simultaneously realizing a quick warm-up for the engine and engine oil/ATF oil is implemented.
