Influence of plate thickness on the eficiency of a permeable planar cooling thermoelement
Keywords:
thermoelectric materials, coefficient of performance, cooling capacity, design of a permeable planar thermoelementAbstract
This paper presents the theory of calculation and computer methods of search for optimal parameters (electric current density, heat carrier flow rate) of a permeable planar cooling thermoelement whereby the energy conversion efficiency will be maximum. The thickness of leg plates of a permeable thermoelement based on Bi-Te at which the coefficient of performance will be maximum is calculated. It is shown that the rational use of such energy converters allows increasing the coefficient of performance by 20-40 %. Bibl. 9, Fig. 2, table 1.
