Problems solved by technology

[0010] Such solutions lead to a reduction in thermal efficiency (especially with iron, which is a poor conductor of heat), a substantial increase in the weight of each fin of the heat sink and, moreover, increased complexity and cost of the manufacturing process and shipping operations

Embodiment Construction

[0018] refer to figure 1 , the radiator fin 1 has a body 2, which is made of aluminum (for example die-cast aluminium) and extends generally along the axis A between the two axial ends 3, 4, with reference to the normal use of the fin 1 In a generally vertical position, the above two axial ends are the upper end and the lower end respectively; the body 2 is provided with an inner cavity 5 defined by the inner surface 6 of the aluminum body 2 for water to flow through. The term "cavity" includes all areas within the fin 1 that in use are wetted by water circulating in the fin 1, and "inner surface" is the defined cavity 5 within the body 2 (and thus in contact with water in use) all surfaces.

[0019] In particular, the body 2 of the fin 1 comprises: at least one main tubular body 7 extending longitudinally along the axis A; two pairs of transversely joined sleeves 8, 9; A plurality of cooling fins and / or cooling plates 10 of the body 7 .

[0020] The tubular body 7 can be s...

Abstract

A heating radiator element (1) having a body (2) made of die -cast aluminium and provided with an inner chamber (5) for passing the water, delimited by inner surfaces (6) of the aluminium body (2), is provided with a protective coating (51) made of an anti- corrosion polymeric coating material applied to every inner surface (6) of the aluminium body (2) so as to completely coat the chamber (5), for protecting in use the inner surfaces (6) of the aluminium body (2) against the contact with water. The application of the protective coating (51) is carried out by filling the chamber (5) with a treatment composition containing the polymeric coating material, and then draining the chamber (5) once the coating material has adhered to the inner surfaces (6) of the chamber (5).

Description

technical field [0001] The present invention relates to a completely anti-corrosion protected heating radiator element, and to a method of anti-corrosion treatment of the radiator element. Background technique [0002] As is well known, die-cast aluminum radiators generally consist of a series of fins which are joined together to form a radiator of suitable size; each fin has an aluminum body with an internal cavity in which heated water circulates. [0003] The ribs generally have a longitudinally extending tubular body and transversely joined sleeves: the ends of the tubular body generally extend along an axis beyond a pair of sleeves and form the bottom of the rib closed by the cover. [0004] Known radiator fins are usually painted on the outside and not on the inside; the internal cavity is thus delimited by aluminum walls whose surfaces are in direct contact with water in use and are left unprotected from corrosion. [0005] In fact, these fins are usually painted by ...
