Heating radiator

The utility model discloses an improved design of a heating radiator, including a radiating tube string (3) and a flake head (1), which has an upper-and-lower water channel. The heating radiator is characterized in that the flake head (1) with the upper-and-lower water channel is a continuous flake head. Each side of a central line of the continuous flake head is equipped respectively with a row of mounting holes, which are used for the radiating tube string. The shape of the mounting holes corresponds with the shapes of the radiating tube string (3). The diameters of both ends of the radiating string are all smaller than the aperture of amounting holes. End covers (2) which are equipped with a thread seat for fixing tubes are welded onto both ends of the continuous flake head. Thus the steel tube radiator has the advantages of simple structure, high production automation; in addition, the utility model saves materials and improves radiating effects and heat energy utilization, thereby reducing production cos
