An objective of the present invention is to control a flow passage of a coolant flowing in a coolant circulation loop according to a temperature of the coolant to promote a quick warm-up of an engine to improve a mileage and stabilize emission. According to the present invention, an apparatus for recovering exhaust heat of a vehicle comprises an engine, an exhaust heat exchanger, a radiator, a water cooling intercooler, and a coolant circulation loop arranged to connect a sub-radiator for cooling the water cooling intercooler. Valves arranged on a flow passage connecting the engine, the exhaust heat exchanger, the radiator, the water cooling intercooler, the sub-radiator, and the coolant circulation loop are controlled according a temperature of a coolant to control temperatures of the coolant and intake air to promote a quick warm-up of the engine. |
