Why is TE Coolers Used for Cooling?
o No moving parts make them very reliable; approximately 105 hrs of operation at 100 degrees Celsius, longer for lower
temps (Goldsmid,1986).
o Ideal when precise temperature control is required.
o Ability to lower temperature below ambient.
o Heat transport controlled by current input.
o Able to operate in any orientation.
o Compact size makes them useful for applications where size or weight is a constraint.
o Ability to alternate between heating and cooling.
o The excellent cooling alternative to vapor compression coolers for systems that are sensitive to mechanical vibration.
Disadvantages
o Able to dissipate a limited amount of heat flux.
o Lower coefficient of performance than vapor-compression systems.
o Relegated to low heat flux applications.
o More total heat to remove than without a TEC.
