TEM Reliability

Reliability is one of the major criterion of thermoelectric module (TEC) selection. TEC’s are considered to be highly reliable components due to their solid-state construction.
However, Kryotherm experience in thermoelectrics made it possible to highlight the following main causes of premature TEC failure:

• TEC improper operation and its faulty mounting, in the first place, which leads to TEC mechanical failure;
• TEC improper installation, which provides poor thermal contact between TEC’s hot side and heat exchanger;
• Insufficient dissipation of heat generated on TEC’s hot side or increased voltage supply, which leads to TEC’s overheating during its operation;
• Fast temperature alteration of TEC’s hot and (or) cold side on wide scale (thermal cycling).
