Structure for operating system for utilizing exhaust heat of vehicle

A structure for operating a system for utilizing exhaust heat of a vehicle, comprising:

• a high-temperature part which includes an exhaust pipe through which high-temperature exhaust gas selectively passes, and a bypass passage which is installed in the exhaust pipe and through which the exhaust gas is selectively bypassed;
• a thermoelectric element which is attached to an exterior of the exhaust pipe, and generates electricity using a thermoelectric effect;
• a low-temperature part which is attached to an exterior of the thermoelectric element in a longitudinal direction and in which a coolant flows;
• a first exhaust gas passage which is installed in the low-temperature part in a longitudinal direction and has both ends connected to the exhaust pipe, and through which the high-temperature exhaust gas selectively passes to heat the coolant;
• a first valve which is attached to an inner circumferential surface of the exhaust pipe, and formed to selectively open or close one end of the first exhaust gas passage;
• a second exhaust gas passage which is formed in a space between the inner circumferential surface of the exhaust pipe and an outer circumferential surface of the bypass passage;
• a second valve which is disposed at a rear end of the bypass passage, coupled to a valve shaft, which is coupled to a side surface of the bypass passage, and installed to be rotatable on the basis of the valve shaft;
• and
• an operating unit which has one end connected to the first valve, and the other end connected to a motor and the valve shaft to allow the first valve to be moved in front and rear directions, and to allow the second valve to be rotated on the basis of the valve shaft, by rotation of the motor.
