Abstract

La presente invenzione illustra un dispositivo (1) di riscaldamento e raffreddamento, in particolare per un cilindro di estrusione, con un elemento (23) per la trasmissione del calore, di forma cilindrica, il quale circonda il mantello, con un elemento di convezione (22) e un dispositivo di riscaldamento per l'elemento (23) di trasmissione del calore. L'elemento di trasmissione (23) del calore circonda il mantello (2) del cilindro di estrusione in direzione circonferenziale, almeno parzialmente, ed è collegato almeno con un elemento di convezione (22) il quale trasmette il calore dell'elemento di trasmissione (23) del calore in direzione radiale.(Figura 1).
