Two section thermoelectric coolers

Two section thermoelectric coolers

 

Designs of two section thermoelectric coolers

An universal abbreviation is used to notate single-stage coolers: ТВ-N-C-h, where:

ТВ — product abbreviation— thermoelectric battery (cooler);

N — number of thermocouples in the cooler;

С — length of the rib of the thermoelectric element basis (in millimeters);

h — height of the thermoelectric element (in millimeters)

For example, in the module TB-161-1,4-1,5: 161 thermocouples (322 thermoelectric elements), every element has the cross-section of 1,4x1,4 mm and is 1,5 mm high.
