Designs of 2-stage thermoelectric modules

System of notation:

An universal abbreviation is used to notate multi-stage coolers: ТВ-n-(N1-N2-N3-N4)-h, where:
ТВ — product abbreviation — thermoelectric battery (cooler);
n — number of stages in the cooler;
N1N4 — number of thermocouples in the first, second, third and forth stages of the thermoelectric cooler.
(N1-N2) is used for two-stage coolers, (N1-N2-N3) — for three-stage coolers and (N1-N2-N3-N4) — for four-stage coolers;
h — height of the thermoelectric element in the bottom stage (in millimeters).
For example, in the cooler TB-2-(11-4)-1.0: 2 stages, 11 couples in the first stage, 4 couples in the second stage, the height of the elements in the bottom stage is 1,0 mm.
