Abstract

Anillo de refrigeración para instalaciones de soplado de láminas con una cámara anular (22) que forma en un borde del contorno una hendidura (23) de salida para la alimentación de un medio de refrigeración sobre la burbuja (14) de la lámina y está dividida mediante bridas radiales (24) en varios segmentos (34), y con elementos incorporados (30,32, 40) para la homogeneización del flujo del medio de refrigeración en los segmentos individuales (34), caracterizado porque los elementos incorporados presentan unas placas (30) de desviación dispuestas oblicuamente respecto a la dirección radial, las cuales desvían una parte del medio de refrigeración de las correspondientes zonas centrales de los segmentos (34) en la dirección hacia las bridas (24).
