Description

Thermoelectric generator using vehicle exhaust heat and manufacturing method thereof {THERMOELECTRIC GENERATOR USING EXHAUST HEAT AND MANUFACTURING METHOD THEREOF}

The present invention relates to a thermoelectric generator using vehicle exhaust heat and a method for manufacturing the same. More particularly, the present invention relates to thermoelectric power generation using vehicle exhaust heat that can convert waste heat into useful electric energy by generating power using exhaust gas heat generated from an engine. An apparatus and a method of manufacturing the same.

In general, when looking at the energy flow of a vehicle, the chemical energy of gasoline is converted into mechanical energy by burning it in an engine, and the thermal efficiency at this time is only about 30%.

The remaining energy is released in the form of heat, in particular the heat generated from the engine is transferred by the coolant and released through the radiator and is released in the form of heat exhaust gas.

Among them, the exhaust gas has the highest heat source, and in general, the exhaust gas is discharged to the outside through the exhaust pipe.

A thermoelectric element is a generic term for a device using various effects caused by the interaction between heat and electricity.Thermistor, a device having a characteristic of negative resistance temperature coefficient, in which electrical resistance decreases with increasing temperature, is used.

Found, used. Specifically, it is as follows. If a temperature difference is applied to both ends A and B of one metal rod, an electromotive force due to the heat flow appears between A and B. Since the electromotive force varies depending on the type of metal, a difference occurs in the electromotive force between A and B appearing in each metal when two types of metal ends A and B are joined, so that a current flows in the circuit. When the middle of one metal is cut off, the difference in electromotive force of two kinds of metals appears at both ends of the cut. This is called heat power. Thermocouples used for temperature measurements use this thermoelectric power.

The thermoelectric power generation using the thermoelectric power is a Seebeck effect that a potential difference occurs between the heat source and the cooling unit when a temperature difference is applied across the Seebeck element, which is a metal or a semiconductor, and directly heats heat without a mechanical driving unit. Can be converted to.
