<p>The invention relates to a heat exchanger radiating element and to a process for making such a heat exchanger by using said type of radiating element, the mentioned heat exchanger being meant to be used as cooling or heating radiators for motor vehicles with internal combustion engines, as oil radiators or coolers for motor vehicles equipped with internal combustion engines or for technological installations, such as evaporators or condensers in the air conditioning apparatuses for motor vehicles, industrial refrigerating storage rooms or installations, and as convection or central heating apparatuses for dwellings, offices, industrial spaces. According to the invention, the radiating element for heat exchangers comprises some tubes (1) bent in the shape of a "U" and some fins (2), the tubes (1) being characterized in that, in the area of the bent sides, namely in the active area of the radiating element, where they come into contact with the fins (2), they have the shape of their cross-section, other than the circular shape, namely the elliptical, oval shape.</p> |
