Abstract
LA PRESENTE INVENCION SE REFIERE A UNA ESTRUCTURA (10) DE PANAL DE MATERIAL CONDUCTOR ELECTRICO QUE ESTA DIVIDIDO ELECTRICAMENTE MEDIANTE RANURAS (13,14) Y/O CAPAS DE AISLAMIENTO ELECTRICO DE TAL MODO QUE UNA CORRIENTE ELECTRICA PUEDE FLUIR A LO LARGO DE UNA VIA (17) DE ARROLLAMIENTO A TRAVES DE LA ESTRUCTURA (10). LA ESTRUCTURA (10) DE PANAL DISPONE DE UNA ZONA (18) DE MATERIAL CON RESISTENCIA ELECTRICA ESPECIFICA MAS ALTA. LA ESTRUCTURA (10) DE PANAL ES DE FORMA PREFERENTEMENTE CILINDRICA O EN FORMA DE CILINDRO OVAL CON RANURAS (13,14) APROXIMADAMENTE AXIALES QUE SE EXTIENDEN, CON LIGERA DESVIACION, DESDE EL EXTERIOR HASTA EL EXTREMO (19) DENTRO DE LA ESTRUCTURA (10) DE PANAL Y EN DONDE LA REGION (18) DE SECCION TRANSVERSAL INTERNA DE LA ESTRUCTURA (10) DE PANAL, QUE COMPRENDE AL MENOS TODOS LOS EXTREMOS (19) DE LAS RANURAS (13,14), CONSISTE EN UN MATERIAL CON UNA RESISTENCIA ESPECIFICA MAS ALTA QUE EN LA REGION EXTERIOR DE SECCION TRANSVERSAL. ESTE DISEÑO FACILITA UNA DISTRIBUCION DE DENSIDAD DE CORRIENTE MAS UNIFORME EN LA ESTRUCTURA DE PANAL Y EVITA LOS PUNTOS CALIENTES. PARTICULARMENTE CUANDO SE UTILIZA COMO CONVERTIDOR CATALITICO CALENTABLE ELECTRICAMENTE PARA VEHICULOS A MOTOR DISPONE DE MAYOR ESTABILIDAD Y DE VIDA DE UTILIZACION MAS LARGA.
