Abstract
ESTA INVENCION PRESENTA UNA ESTRUCTURA EN NIDO DE ABEJA EN QUE LA CONCENTRACION DE ESFUERZOS SOBRE UNA PLACA PLANA EN EL AREA DE SOLDADURA A UNA PLACA CORRUGADA SE EVITA EN EL AREA LATERAL EXTERIOR DE LA ESTRUCTURA EN NIDO DE ABEJA, POR EJEMPLO, LA PRIMERA Y LA SEGUNDA CAPAS DESDE EL EXTERIOR DE LA MISMA, CON LO QUE SE EVITAN LAS GRIETAS Y LA EXFOLIACION DE LA PLACA PLANA EN EL AREA DE LA SOLDADURA Y TAMBIEN SE PROTEGE AL NUCLEO PARA QUE NO SE SALGA. EN LA ESTRUCTURA EN NIDO DE ABEJA 5, LA PLACA CORRUGADA 3 Y LA PLACA PLANA 1 SE COLOCAN DE MANERA ALTERNA Y SE SUELDAN PARA FORMAR UN BLOQUE ENROLLADO. EN UN LUGAR NO MAS ALLA DE AL MENOS DOS CAPAS DESDE EL EXTERIOR DE LA ESTRUCTURA EN NIDO DE ABEJA 5 SE UTILIZAN DOS HOJAS DE PLACAS PLANAS 1 A MODO DE PAR DE TAL MODO QUE QUEDEN SUPERPUESTAS SIN QUE HAYA UNA SOLDADURA ENTRE MEDIAS. CUANDO LA ESTRUCTURA EN NIDO DE ABEJA 5 SE UTILIZA EN UN ENTORNO EN DONDE SE REPITEN LOS CICLOS TERMICOS DE CALENTAMIENTO Y REFRIGERACION, LA CARA EXTERIOR DE LA MISMA SIEMPRE SE REFRIGERA CON AIRE LIBRE MIENTRAS QUE LA CARA INTERIOR NO SE REFRIGERA Y COMO RESULTADO, SE PRODUCE UNA DIFERENCIA ENTRE LA CANTIDAD DE EXPANSION Y CONTRACCION TERMICA DEBIDO A LA DIFERENCIA DE TEMPERATURA Y SE GENERA UN ESFUERZO. SIN EMBARGO, ESTE ESFUERZO QUEDA AMORTIGUADO CON LAS DOS HOJAS DE PLACAS PLANAS 1 SUPERPUESTAS.
