Thermoelectric power generation system for vehicle
A thermoelectric power generation system for a vehicle is provided. The system includes an air compressor that is configured to compress and discharge air and a vortex tube that is configured to receive the compressed air discharged from the air compressor and separate and discharge the compressed air into two groups of air having a temperature difference. In addition, a thermoelectric module is provided that includes a thermoelectric element having a channel formed at a first side thereof introduced with any one of the two groups of air and a channel formed at a second side thereof introduced with the other of the two groups of air to generate an electromotive force due to a temperature difference of the two groups of air.
1. A thermoelectric power generation system for a vehicle, comprising:
an air compressor configured to compress and discharge air;
an air tank configured to store the compressed air discharged from the air compressor via an air drier;
a vortex tube configured to receive the compressed air discharged from the air compressor and stored in the air tank and separate and discharge the compressed air into two groups of air having a temperature difference;
a thermoelectric module that includes a thermoelectric element having a channel formed at a first side thereof introduced with a first group of the two groups of air and a channel formed at a second side thereof introduced with a second group of the two groups of air to generate an electromotive force due to the temperature difference of the two groups of air; and
a valve disposed between the air compressor and the vortex tube,
wherein a controller is configured to adjust an operation amount and an operation time of the valve based on information regarding a pressure of the compressed air and a compressed air quantity received from the air compressor and a state of charge from a battery.
2. The thermoelectric power generation system for a vehicle of claim 1 , wherein the
a battery is connected to the thermoelectric element to store the electromotive force generated from the thermoelectric element.
3. The thermoelectric power generation system for a vehicle of claim 1 , further comprising:
a muffler connected to the thermoelectric module to accommodate air discharged from the channels to attenuate noise and discharge the attenuated noise to the exterior.
4. The thermoelectric power generation system for a vehicle of claim 1 , wherein the compressed air stored in the air tank is supplied to an air brake system, an air suspension system, and the vortex tube.
