Steel-aluminum composite radiator capable of radiating at multiple angles

The steel-aluminum composite radiator comprises a radiator body, upper bearings are fixedly connected to the top wall of the interior of the radiator body at equal intervals, upper rotating shafts are rotationally connected to the inner sides of the upper bearings, lower bearings are fixedly connected to the bottom wall of the interior of the radiator body at equal intervals, and lower rotating shafts are rotationally connected to the inner sides of the lower bearings. A lower rotating shaft is rotationally connected to the inner side of the lower bearing, cooling fins are fixedly connected between the upper rotating shaft and the lower rotating shaft, and rotating rods are rotationally connected to the upper portion and the lower portion of the interior of the radiator body correspondingly. According to the utility model, the angle of the independent radiating fin can be adjusted through the cooperative use of the rotating rods and the rotating shaft, the upper bearing and the upper rotating shaft, and the l
