THIS IS A PPT ON "CONVERSION OF THERMAL ENERGY INTO VOLTAGE USING THERMOELECTRIC MODULES". IT INCLUDES: A SHORT INTRO THERMOELECTRIC MODULES WORKING & CONSTRUCTION EXPERIMENT PART PROBLEMS & BENEFITS CURRENT USES FUTURE SCOPES HOPE YOU FRIENDS LIKE MY WORK.

1. NAME: SIMRAN GUPTA ROLL NO:19/439

2. WHAT IS IT
• We need to convert heat to electricity.
• Heat to mechanical to electrical.
(heat>steam>turbine>generator)
• Thermoelectric generator
(heat>electricity)
• Needs temperaturedelta.
• Need hot and cold.

3. Thermoelectric Module
• Thermoelectric module is an
array of Thermocouple
connected electrically in series
but thermally in parallel
• Many couples are used in both
power generation and cooling
because the voltage drop
across one couple is only on the
order of millivolts

4. WORKINGS
• Thermoelectric materials.
• Temp differences<electric volatage
• Material junction creates electron
flow
• High electrical conductivity
• Low thermal conductivity is a must.

5. CUNSTRUCTION
• Semi conductor are the best
Candidate.
• P type and N type is used in
series.
• Many small cell in series
• ThermalSurface is in parallel.
• A solid state heat PUMP

7. Experiment
• Connect the thermo electric module to the Multimeter.

8. • Supply heat with the lighter to the module surface , and you will get the
Voltage supply reading on the Multimeter display.

9. PROBLEMS & BENEFITS
• PROBLEMS:
• Efficiency of TEGs is around 5 to 8%
effective.
• Needs large Temp Difference.
• Constant Heat Supply
• BENEFITS:
• Environmet friendly
• Recycle wasted heat energy.
• Lower production cost
• Silent in Operation

10. USES
• Light house
• Research Station
• CoolingComputer
• Recharging Devices
• Nuclear power Station
• Water cooler

11. FUTURE
• Best Power Source for deep space
• New material for efficiency.
