Round thermoelectric coolers

Round thermoelectric coolers

 

Designs of round thermoelectric coolers

To notate thermoelectric coolers with a hole, a system of notation of standard single-stage thermoelectric coolers with an index is used: ТВ-N-C-hBB, 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)

BB — additional index:

  • CH — for rectangular modules with a central hole (for example ТВ-43-1.0-0.8CH)
  • CHR — for round coolers with a central hole (for example ТВ-19-1.0-1.3CHR)
  • R — for round coolers (for example TB-253-1.4-1.5R)
