Patent ID: 8919298

Claim:
An integrated heat management system in a vehicle, comprising: an engine system including: an engine; a radiator; a low-temperature cooling water line connecting the engine and the Radiator to provide low-temperature cooling water from the radiator to the engine; a high-temperature cooling water line connecting the engine and the Radiator to discharge high-temperature cooling water coming out of the engine to the radiator; and a heater core coupled to the high-temperature cooling water line; a transmission system including: an automatic transmission fluid (ATF) discharge line coming out of an automatic transmission and discharging ATF to a heat exchanger; and an ATF supply line coming out of the heat exchanger so as to be linked to the automatic transmission and circulating the ATF through the automatic transmission; an exhaust heat recovery system connected the engine and using engine heat coming out of the engine; a circulation flow system forming a flow path which connects the engine system and the transmission system; and a control valve having one or more input and output ports which are opened and closed by control of an engine control unit (ECU) receiving vehicle information during engine start-up, and form the flow path of the circulation flow system into a variety of cooling water circulation flow paths; wherein the circulation flow system comprises: an engine system circulation line which connects the engine and the exhaust heat recovery system and connects the heater core and the engine; and a transmission system circulation line which connects the engine and the exhaust heat recovery system and connects the heat exchanger and the engine; and wherein the engine system circulation line and the transmission system circulation line are connected to different input ports and different output ports of the control valve, respectively.
