Abstract
UNA REJILLA TROQUELADA PARA PLACA UNITARIA INFERIOR DE UNA PIEZA TIENE UNA PORCION INFERIOR Y UNA PORCION SUPERIOR PARA SOPORTAR LAS VARILLAS DE COMBUSTIBLE. LA REJILLA TROQUELADA PARA PLACA INFERIOR INCLUYE PORCIONES ESTAMPADAS CILINDRICAS QUE SE EXTIENDEN SUPERIORMENTE DESDE LA PORCION INFERIOR DE REJILLA Y DISPUESTA EN MATRICES CUADRADAS PARA RECIBIR LOS TAPONES TERMINALES INFERIORES DE LAS VARILLAS DE COMBUSTIBLE. PORCIONES DE TRAMA QUE SE EXTIENDEN SUPERIORMENTE DESDE LA PORCION TROQUELADA DE PLACA INFERIOR INTERCONECTAN LAS PORCIONES ESTAMPADAS A LO LARGO DE LOS LADOS DE LAS MATRICES. LA PORCION INFERIOR DE REJILLA INCLUYE UNA PLURALIDAD DE ABERTURAS QUE SE ABREN DENTRO DE LOS ESPACIOS DE FLUJO DEFINIDOS POR LAS PORCIONES CONVEXAS DE LAS ESTAMPACIONES Y LAS TRAMAS DENTRO DE CADA MATRIZ CUADRADA DE LA PORCION SUPERIOR DE LA PLACA TROQUELADA. REFRIGERANTES FLUYEN A TRAVES DE LAS ABERTURAS DENTRO DE LOS ESPACIOS PARA FLUIDO PARA FLUIR ADICIONALMENTE SUPERIORMENTE ALREDEDOR DE LAS VARILLAS DE COMBUSTIBLE. LAS ABERTURAS SON REDONDEADAS EN LA ZONA ADYACENTE A SUS EXTREMOS INFERIORES Y TIENEN PAREDES LATERALES DIVERGENTES CORRIENTE ABAJO DEL AREA DE GARGANTA PARA DEFINIR UN FLUJO DE VENTURI.
