Abstract:
1. A structure for utilizing exhaust heat of a vehicle, comprising: a first part that includes an exhaust pipe in which exhaust gas having a predetermined temperature passes through and which is heated by exchanging heat with the exhaust gas, and a bypass passageway installed within the exhaust pipe and through which the exhaust gas is bypassed; a thermoelectric element attached to an exterior of the exhaust pipe, formed by bonding a P-type semiconductor and an N-type semiconductor, and configured to produce electricity using a thermoelectric effect; a second part attached to the exterior of the thermoelectric element and in which coolant flows; a first exhaust gas passageway installed within the second part in a longitudinal direction and in which the exhaust gas passes through to heat the coolant; and a first valve formed between the exhaust pipe and the first exhaust gas passageway and slidably installed to open and close the first exhaust gas passageway, wherein operations of warming up an engine and generating thermoelectric power are performed simultaneously.
