Million cycles superior cooling Peltier thermoelectric module TETC1-12712S-74

     The 127 couples, 40 mm * 40 mm size single stage module is made of selected high performance ingot and fabricated by our unique “soft” processes to achieve superior cooling/heating performance. The module is able to run million thermal cycles in 70 °C temperature change range with less 3% degrading. It is good for the need of frequently cooling down and heating up to 100 ºC applications. If higher operation or processing temperature is required, please specify, we can design and manufacture the custom made module according to your special requirements.

 Standard Performance Graph Qc= f(ΔT)

 Standard Performance Graph V= f(ΔT)

 Standard Performance Graph Qc= f(V)

 Standard Performance Graph COP = f(V) of ΔT ranged from 0 to 30 ºC 

Standard Performance Graph COP = f(V) of  ΔT ranged from 40 to 60/70 ºC

 Remark: The coefficient of performance (COP) is the cooling power Qc/Input power (V × I).

          A typical 127 couples module is fabricated by the unique “soft” process and has demonstrated that it only has 2.5% degrading after 300,000 thermal cycling. The below graphic shows that in beginning 120,000 cycles, it degrade about 2.5%, and then go on stable with very tiny degrading in further 180,000 thermal cycles. It is derived out that the modules can go over million thermal cycles.
