P11462: Thermoelectric and Fan System for Cook Stove

Additional Mechanical Considerations

Once a size was obtained for the heat conduction beam we were interested in looking into transient effects and effect of varying the overall heat transfer coefficient. Using heat transfer theories these results were obtained:

Based on a lumped capacitance analysis: Time to reach a 300 deg C steady-state temperature: 10.42 min

Variation of hot-side temperature of thermoelectric:

With low value of U = 24.2 W/m-K -- 190 deg C
With high value of U = 44.2 W/m-K -- 380 deg C
With low fire temp = 700 deg C -- 75 deg C
With high fire temp = 1100 deg C -- 475 deg C
