1 . KRAINE. THERMOELECTRIC COOLING MODLES OF INCREASED COOLING POWER ALTEC - 2, 31, 33, 35, 36 Information is given on Peltier modules of incriased cooling power: Altec-2, Altec-31, Altec, Altec-35, Altec-36. Te module is intended for creation of required temperature modes in different products wit termoelectric cooling, termostatting or conditioning. Commonly used module for development of ouseold appliances, conditioners, medical equipment, measuring instruments, metrology, oter goods and devices. Te module is a modification of a known and widely used module wit ceramic plates of x mm and wit couples of legs. Compared to standard modules xmm, te modules offer increased cooling power. For example, in cooling power one Altec-31 module replaces two standard modules x mm, and one Altec-35 module replaces tree standard modules xmm. In tis case te price of Altec-35 module is nearly equal to te price of standard module xmm. Terefore, using module Altec-35, te customer actually can ave 3-fold reduction of module cost Te information on modules is given in te table. Te module offers improved caracteristics of reliability and stability to various effects. Te module as been designed on te basis of te latest tecnological acievements of te Institute of Termoelectricity, National Academy of Science, kraine. In designing te module use as been made of te latest teory of termoelectric modules reliability developed in te Institute of Termoelectricity National Academy of Science, kraine. In designing te module use as been made of te results of extensive reliability tests of modules conducted by te Institute of Termoelectricity, National Academy of Science, kraine, during te recent 25 years. Tecnologies of te Institute of Termoelectricity were marked wit te "International Golden Award for Tecnology and uality". Te module utilizes connecting copper plates wit anti-diffusion coatings Al 2 O 3. Te module utilizes connecting copper plates wit anti-diffusion coatings. Te module utilizes ig quality termoelectric materials of own production based on Bi-Te-Se-Sb. Te materials ave small-angle controllable unit crystal disorientation, to provide ig figure of merit combined wit increased mecanical strengt. Te module utilizes multi-layer anti-diffusion barriers 25 reliability and long service life. μm tick, to provide ig Te modules utilize plastic connecting solders wit controlled tickness, to provide ig resistance to cyclic temperature effects. Te modules utilize efficient tecnologies for leg material joining wit anti-diffusion barriers. Te engagement strengt reaces te leg material strengt.

2 Te modules utilize igly efficient silicone sealants wic ave undergone multi-year tests under conditions of outer space, elevated umidity, etc. According to customer's wis, te outside surfaces of ceramic plates may ave metallization and be coated wit solder. In tis case te modules can be attaced to cooled objects by soldering. Wit suc attacment eat losses because of termal resistances at points of modules attacment become negligible. Basic parameters of modules: Modules type Dimensions, mm а b c max, V I max, A o, W ΔT max, K Altec Altec Altec Altec Altec dimensions: a = mm; b = mm; c = 3. mm (See Fig. 1); max. operating voltage max =15 V; max. operating current I max =11.6 A; operating temperature range - K; max. cooling power at 3 K =1 W; max. temperature difference at ceramic ot side temperature T =3 K is Δ T max = ± 2 K; input leads lengt l = 15 mm; lengt of leads witout insulation l =1 mm
