The invention relates to a parabolic device for concentrating solar radiation, which allows the distribution of solar radiation per unit of area to be optimised, reducing the number of solar concentrators necessary to supply thermal energy in industrial processes, especially in mining. The device is formed from two main elements: a concentrator unit that includes three reflective surfaces, section a, section b and section c formed between points (1), (2), (3) and (4), allowing solar radiation to be reflected on two points (optical focuses), thereby enabling the volumetric flow of heated liquid to be doubled, points (1), (2), (3) and (4) being formed by placing parabola 1 on top of parabola 2, on the same axis, and sections a, b and c being covered by stainless steel mirror; and a support structure located at the centre of each end of the unit and formed by two rings (5) and (7) joined together by means of soldering to a metallic square profile (6). The support structure gives rigidity and acts as the support base for the designated element for capturing the solar radiation concentrated on the focuses.
