Theoretical basis of thermoelectric power generation

According to Seebeck effect, open circuit (no load) voltage U=a (Th Tc)=a* ΔТ-- Formula ①
Considering load, output voltage=a* ΔТ* RL/(Ri+RL) --------------- Formula ②
Current in the circuit I=U/(Ri+RL)=a* ΔТ/ (Ri+RL) --------------- Formula ③
When no load RL=0, it is called an open circuit, and the open circuit current I=a* ΔТ/ Ri -------- type ④
From P=UI, output power=a* ΔТ* RL/(Ri+RL) *a* ΔТ/ (Ri+RL)
That is, P=a 2* ΔТ 2 * RL/(Ri+RL) 2 ------------ Formula ⑤
When Ri=RL, P=Pmax=a 2* ΔТ 2/(4Ri) -------------------- Type ⑥
According to formulas ⑤ and ⑥, the output power is proportional to the square of the temperature difference.
The maximum output power is inversely proportional to the internal resistance of the device.
According to formula ②, the larger the load resistance is, the greater the output voltage will be.


Application Considerations

Application Considerations

● The generator module must be installed on a flat surface, and the flatness of the contact surface is required to be more than 30 microns.
● It is suitable for long-term operation under the condition that the hot end temperature is 0~200 ℃.
● Please obtain the maximum operating temperature from customer service.
