<p>Spacer element (10) able to be inserted between the walls (32) of a panel (31) of a heat radiator (30) in correspondence with an aperture (34) for the transit of the heat carrier fluid circulating between the walls (32). The spacer element (10) comprises a substantially cylindrical body (11) provided both with an axial hole (13), which affects at least a part of its thickness and which faces towards the transit aperture (34), and also a lateral aperture (15) which branches off radially from the axial hole (13) and communicates therewith. The body (11) in turn comprises two metal pieces (18,19) of substantially cylindrical shape, coaxially attached one on the other, of which at least one is made of sintered material and in which the lateral aperture (15) is made and which also comprises at least two radial holes (16) or hollows (17), each of which branches off radially from said axial hole (13) and communicates therewith.</p> |
