TOTAL ANTICORROSION PROTECTION HEATING RADIATOR ELEMENT, AND METHOD OF ANTICORROSION TREATMENT OF HEATING RADIATOR ELEMENTS

摘要

A heating radiator element (1) has a body (2) made of die -cast aluminium and provided with an inner chamber (5) for water circulation, delimited by inner surfaces (6) of the aluminium body (2); the inner chamber (5) is entirely coated with a protective coating (51) made of an anti- corrosion polymeric coating material which protects in use the inner surfaces (6) of the aluminium body (2) against the contact with water; the body (2) has an end part (25) which extends beyond a pair of transversal coupling sleeves (9), connected to the chamber (5) by means of respective holes (29) delimited by peripheral edges (30), and having a bottom opening (27) closed by a cap (28); the cap (28) has a closing surface (33) arranged within the end part (25) very close to the holes (29) which connect the sleeves (9) to the chamber (5) and specifically substantially tangent to the holes (29).
