The Reliability of Thermoelectric Coolers in Thermal Cycling Process (I)
In order to research the influence of thermal cycling to TECs, we need to define thermal cycling first. In most applications, many thermoelectric components are suffering periodic temperature rise and fall, which may be in a wide temperature range. Although the boundary between cycling and non cycling working conditions is not obvious, but in general, we define thermal cycling as a working condition, under which temperature rises and falls continuously and regularly in a very long time. This condition generally refers to auto temperature control or mechanical temperature control, not manually control. If there are only several cycles of temperature rise and fall, we don't call it thermal cycling.
The failure rate in thermal cycling is related at least four factors: 1. The total cycling times; 2. The total temperature change range in thermal cycling; 3. The upper temperature limit; 4. The speed rate of temperature change.
