[0012] like Figs. 1-2 As shown, this utility model discloses a pipe-type riveted radiator, comprising a base plate 1. Two or more fixing slots 4 are arranged parallel to each other on the upper side of the base plate 1. Each fixing slot 4 has a radial cross-section including an arc or semicircle. Each fixing slot 4 contains a copper pipe 2. Both ends of each copper pipe 2 are bent at 90 degrees and extend upwards. The upward extension directions of both ends of each copper pipe 2 form an angle between 45 and 90 degrees with the base plate 1. Any two adjacent copper pipes 2 are parallel to each other. At least one [unclear - possibly a device or feature] is provided above each fixing slot 4. A riveting component 3 is provided in the bottom plate 1 on both sides of any fixed groove 4, and the riveting component 3 is riveted to the riveting structure 5.
