<p>A plurality of a U-shaped heat radiation plates (1a,1b) are provided on a heat radiating tube. These U-shaped plates (1a,1b) have different sizes and are elongated in the same direction so as to cross an axis of the tube. The emissive heat radiator may also include at least one radiating plate (2) substantially perpendicular to each axis of the U-shaped plates (1a,1b). A concave surface of the U-shaped plate (1a,1b) is subjected to a radiation surface processing, and a convex surface (1ab) thereof is subjected to a reflection surface processing. <IMAGE></p> |
