3.75V Thermoelectric Power Module For Cabinet Cooling Device
Peltier Effect
• When an electric current flows through two dissimilar conductors, depending on the direction of the current flow, the junction of the two conductors will either absorb or release heat.
•The heat absorbed or released at the junction is proportional to the electrical current. The proportionality constant is known as the Peltier coefficient.
Q = π*I
where π = Peltier coefficient
and I= junction current
• Thomson (Lord Kelvin) showed the relationship between the Seebeck and Peltier coefficients as:
π = αT T = temperature of the junction (°K)
α = Seebeck Coefficient (V/°K)
• Semiconductors are materials of choice for producing the Peltier effect.
–They are more easily optimized for pumping heat
–Designer can control the type of charge carrier employed within the conductor
•With semiconductor advancements, thermoelectric modules can now be produced to deliver efficient solid state heat pumping for both heating and cooling. | Model | TEC1-3105T |
