Particularly reliable thermoelectric cooling modules for use in space-purpose products


General parameters of modules:

  • Аltec-028, dimensions, mm (40x40x3,8); Umax =7,4 V; Imax =12 А; Qo=54,5 W; ΔTmax=72*2 К
  • Аltec-029, dimensions, mm (40x40x3,8); Umax =3,6 V; Imax =24 А; Qo=53,7 W; ΔTmax=72*2 К

Innovative Aspect and Main Advantages

The modules offer improved reliability as compared to conventional modules 40x40 mm owing to special electric connection of elements. The reliability increase is from 80 to 350 times.

In the design of the modules use was made of the results of extensive reliability tests of modules carried out by Institute of thermoelectricity during recent 25 years.

The modules utilize connecting copper plates with antidiffusion coatings.

The modules utilize high-quality home-made thermoelectric materials based on Bi-Te-Se-Sb, to provide a high thermoelectric figure of merit combined with increased mechanical strength of material.

The modules utilize efficient multilayer antidiffusion barriers 25 mm thick, to provide high reliability and long service life.

The modules utilize plastic connecting solders of controlled thickness, to provide high module resistance to cyclic temperature effects.

The modules utilize highly efficient silicone sealants that were successfully tested under conditions of outer space, increased humidity, etc.

Areas of Application

The modules are intended for providing the necessary temperature modes in space and household cooling products, airconditioners, other goods and devices.

Stage of Development

Tested, available for demonstration – field tested. Already on the market.
