  • the triangular protrusion 518p is formed as follows. First, as shown in FIG. 5C, a regular octagonal outline 518pe is ruled on the horizontal plate 518c.
  • the contour 518pe has a size such that the distance between opposing vertices of the regular octagon (the length of the straight line when both ends of the straight line passing through the centroid are aligned with the top of the regular octagon) is about 10 to 20 mm. It has become.
  • incisions are made from the end points of each side of the regular octagon forming the contour 518pe toward the centroid of the contour 518pe (a total of eight). Then, since eight congruent triangles are formed inside the contour 518pe, these are bent along the contour 518pe at a right angle to the surface of the horizontal plate 518c.
  • the horizontal plate 518c is formed with a plurality of contours 518pe (12 in this modification) on which eight triangular protrusions 518p are formed.
  • the front edge effect is exhibited in the first side plate 18a and the second side plate 18b in the same manner as the heat collection plate 18 (see FIG.
  • the temperature-controlled air A flowing along the horizontal plate 518c collides with the triangular protrusions 518p and the flow is disturbed, so that the high-temperature portion and the low-temperature portion in the temperature-controlled air A are efficient.
  • the effect of promoting heat transfer is exhibited. That is, in the heat collecting plate 518, the triangular protrusion 518p functions as a disturbance promoting body.
  • the triangular protrusion 518p is formed on the horizontal plate 518c.
  • the first side plate 18a and / or the second side plate may be replaced with the horizontal plate 518c or together with the horizontal plate 518c. It is good also as forming in the board 18b.
  • FIG. 6 is a view showing a heat collecting plate 618 according to a third modification, wherein (A) is a front view seen from the upstream side in the reference direction D, and (B) is a plan view.
  • the heat collecting plate 618 is different from the heat collecting plate 18 (see FIG. 1) in that a horizontal plate 618c on which fin-type protrusions 618p are formed is provided.
  • the fin-type protrusion 618p includes a fin-type upper protrusion 618pt protruding to the top plate 12 side and a fin-type lower protrusion 618ps protruding to the floor surface Bf side.
  • the fin-type upper protrusion 618pt and the fin-type lower protrusion 618ps protrude in the direction intersecting the reference direction D, respectively.
  • the fin-type protrusion 618p is formed as follows in this modification. First, an outline of a rectangle (15 mm ⁇ 5 mm in this modification) elongated in the reference direction D is drawn on the horizontal plate 618c. In this modification, six rectangular rows arranged at equal intervals in a direction orthogonal to the reference direction D are marked with another row (two rows in total) spaced in the reference direction D. Next, the rectangular outline is cut along the other three sides, leaving one long side.
  • the fin-shaped protrusion 618p is formed by bending a rectangular piece at a right angle along the remaining long side.
  • the fin-type protrusion 618p is formed on the horizontal plate 618c.
  • the first side plate 18a and / or the second side plate 618c is replaced with or together with the horizontal plate 618c. It may be formed on the side plate 18b.
