Abstract EN

The electrothermic cooling system, proposed by German scientist (Altnkerh) in 1934, the latest cooling systems known.

The electrothermic cooling system is built on the property semiconductor materials which absorb heat during the cold and links to expel heat through hot links as a result of the different electromotive force of the semiconductor material in the joints.

Was prepared test specimens in a manner powder metallurgy, where used powders with particles size convergent for the purpose of obtaining agglutination good between atoms, mixed powders for a period of five and a half hours for the purpose of obtaining the homogeneity of mixing prepared, then create part of the powder for the purpose of conducting the process of pressing pressure different then sintered powder at (450°C) at this stage will interfere components with each other so as to obtain compounds of the elements used then underwent a series of tests necessary for the alloy, such as measuring the thermal conductivity and checking the electrical resistance and examine the X-ray diffraction (XRD), and the results obtained is to increase the coefficient of thermal conductivity increase applied pressure and the time of sintering as well as increase the electrical resistance increase the time of sintering, where up to resistance (0.09Ω) when using sintering time two hours and a half.
