Abstract
An integrated heat management system may include an engine system circulation line around an engine and a transmission circulation line around an automatic transmission. The engine system circulation line and the transmission circulation line may be integrated by a control valve having a plurality of input and output ports. The integrated heat management system controls opening and closing of the control valve in accordance with engine cooling water temperature and automatic transmission fluid (ATF) temperature, which may be changed after engine start-up, and implements a variety of modes for varying an engine cooling water flow. Therefore, the integrated heat manage system shortens an engine warm-up time, prevents a bad effect in a low-temperature state due to a fast temperature increase of the ATF, and satisfies performance required by a vehicle of which the fuel-efficiency may be improved and the efficiency may be increased in a high oil price environment.
