How Thermoelectric Modules Work
A typical single-stage thermoelectric module consists of two ceramic plates with both p-type and n-type semiconductor material between them. The semiconductor elements are connected electrically in series and thermally in parallel.
When a DC current is applied to a thermoelectric n-type element, the electrons move from a lower to a higher energy state as they ow into the material at the cold end. This results in the absorption of heat from the surrounding area. The heat is carried through the cooler by electron transport. The heat is released at the hot end as the electrons leaves the element. P and N-type elements are used in pairs, called couples (see Figure 1). The heat-pumping capacity of a single cooler is detemined by the number of couples used in the cooler and the amount of current.
