Abstract
EL INVENTO SE REFIERE A UN ELEMENTO MODULAR CAMBIADOR DE CALOR, ESPECIFICAMENTE DISEÑADO PARA CILINDROS DE EXTRUSION, MAQUINAS DE MOLDEO POR INYECCION, ESTIRADORAS Y MAQUINAS SIMILARES DE PROCESO DE PLASTICOS. EL CAMBIADOR DE CALOR CONSTA DE VARIOS SEGMENTOS EN FORMA DE SEMICORONA, ACOPLADOS PARA DEFINIR UNA CORONA CIRCULAR QUE PUEDE APLICARSE ALREDEDOR DEL CUERPO. LOS SEGMENTOS PUEDEN APILARSE AXIALMENTE Y LLEVAN ALETAS QUE SE EXTIENDEN RADIALMENTE Y QUE INCLUYEN AGUJEROS. ADEMAS, EN AMBAS CARAS DE LOS SEGMENTOS EXISTEN ENTRANTES PARA ALOJAR UNA RESISTENCIA ELECTRICA. UNA ENVOLTURA EXTERNA DEFINE, EN COOPERACION CON LOS SEGMENTOS, UN TRAZADO DE CONDUCCION DE AIRE QUE SE EXTIENDE SUCESIVAMENTE SOBRE LA SUPERFICIE INTERNA Y EXTERNA DE LOS SEGMENTOS.
