What Does Imax Mean
•Imax is the direct current level which will produce the maximum possible ΔT, (i.e. ΔTmax), across the TEC with no heat load (Q=0). .
•Imax Operating below Imax there is insufficient current to deliver the ΔTmax
•Operating above Imax the power dissipation within the thermoelectric begins to elevate the system temperature and diminish ΔT.
•Imax and Vmax occur at the same operating point, i.e. Imax is the current level produced by applying Vmax to the thermoelectric device.
•Imax is not especially temperature-dependent. It tends to be fairly constant throughout the operating range of a thermoelectric device.
•Imax is NOT the maximum current that the TEC can withstand before failing.
•Thermoelectrics generally operate within 25% - 80% of the maximum current.
What Does Vmax Mean •Vmax is the DC voltage which will deliver the maximum possible ΔT (i.e. ΔTmax), across the TEC with no heat load (Q = 0)
•At voltages below Vmax, there is insufficient current to deliver ΔTmax
•At voltages above Vmax, the power dissipation within the thermoelectric begins to elevate the system temperature, and diminish ΔT.
•Imax and Vmax occur at the same operating point, i.e. Imax is the current level produced by applying Vmax to the thermoelectric device.
•Vmax is temperature-dependent. The higher the Thot , the higher the Vmax rating for a specific device.
•Vmax is NOT the maximum voltage that the thermoelectic device can withstand before failing.
What Does Qmax Mean •Qmax is the maximum load to the thermoelectric device that produces ΔT = 0.
•Qmax, Imax, and Vmax occur at the same operating point to produce ΔT= 0.
•It specifies an end point on the load line.
•Qmax does not project the maximum heat that can be handled by the thermoelectric device.
–If the load goes beyond, the TEC will still pump the heat, but the thermal load simply winds up at an above-ambient temperature. (i.e. you have to look at different performance curve.)
