To notate thermoelectric coolers with a hole a system of notation of standard single-stage thermoelectric coolers with an index is used:

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)

Qmax：热电致冷器的最大冷却能力。当热电致冷器的热面和冷面之间保持温差为零，逐渐升高热电致冷器的电流到最大电流Imax。此时，热电致冷器达到最大冷却能力。

例如：TB-161-1.4-1.5模块: 161是热电偶对数，(322是热电偶的元素)
