The Team
Thermoelectrics
are awesome!!
Project Background
 Up to 60% of the energy in a combustion engine can
be lost in the form of waste heat
 Recovering lost heat and converting it into energy may
prove to be an efficient and cost effective power
generation method.
 Thermoelectric modules may be a solution.
Thermoelectrics can produce electrical energy from
heat.
Thermoelectric Operation
• Create energy from a temperature differential
• The larger the temperature difference the larger the
power output
Cold Side:
Need to remove
as much heat as
possible.
Hot Side:
Need to supply as
much heat as
possible
Major Needs and Specifications
65+ Watts
Charge
Battery
• Need to produce more than 65 Watts
• Ideally produce 100 Watts of power
• Use the generated power to charge a car battery
• Need to design circuitry to regulate the voltage
Design Concept:
Finned heatsinks for cost
effective and feasible
cooling
15 internal fins to
transfer exhaust
heat to
thermoelectric
modules
Bellvue springs to control
contact pressure under
thermal expansion.
