いても同様な問題があった。However, since the plate body 2 used for the heat sink has a substantially comb-shaped cross section and the front and back surfaces are symmetrical, the plate body 2 is extruded using a die. Since there is a difference in the flow velocity and flow rate of the metal passing through the die, friction resistance or temperature,
As shown in FIG. 5, a phenomenon occurs in which the plate body 2 bends toward the surface having the groove 3. For example, the width of the plate 2 is 400
mm, the plate 2 has a thickness of 14 mm, and the groove 3 has a depth of 3 mm.
In the case of No. 1, a bending of about 3 mm occurs. Therefore, there is a problem that the dimensions between the grooves 3 and the parallelism between the grooves 3 are not uniform, the adjacent fins 4 contact each other, or the caulking portion becomes insufficient. Further, the same problem occurs in the plate-shaped members whose front and back surfaces other than the plate 2 of the heat sink have symmetrical shapes.
