Here, the first constant change plate 13 may be disposed on both left and right sides of the first gradation plate 11; the first constant-change plate body 13 can be matched with the second gradual-change plate body 12 for use; for example, the first constant change plate 13 is provided on the left side of the second gradation plate 12; the first constant variable plate body 13 is arranged on the right side of the second gradual change plate body 12; the arrangement mode is substantially the same as that of the first gradation plate 11, and will not be described in detail here.

It can be seen that the first constant change plate 13 has substantially the same structure as the first gradual change plate 11 or the second gradual change plate 12, and the difference is that the first constant change plate 13 is a non-gradual change molding area, and the first gradual change plate 11 and the second gradual change plate 12 are gradual change molding areas; therefore, the first gradual change plate body 11 is matched with the first constant change plate body 13 for use, so that a user can obtain different modeling curvatures on the same heat conducting plate 10, and the use is more flexible.

Fourth embodiment

The first invariable plate 13 is arranged on the left side and/or the right side of the first gradual change plate 11 along the first extending direction x1 of the heat conducting plate 10, or the first invariable plate 13 is arranged on the left side and/or the right side of the second gradual change plate 12 along the first extending direction x1 of the heat conducting plate 10; or the first invariable plate 13 is disposed between the first gradual plate 11 and the second gradual plate 12 along the first extending direction x1 of the heat conducting plate 10.

For example, the first constant variable plate 13 is disposed on the left side of the first gradient plate 11, so that the first constant variable plate 13, the first gradient plate 11, and the second gradient plate 12 are sequentially disposed along the first extending direction x1 and integrally formed.

Or, the first constant variable plate 13 is disposed on the right side of the second gradual change plate 12, so that the first gradual change plate 11, the second gradual change plate 12 and the first constant variable plate 13 are sequentially disposed along the first extending direction x1 and integrally formed.

Alternatively, the first constant variable plate 13 is arranged on the right side of the first gradual change plate 11, and the left side of the second gradual change plate 12, that is, the first constant variable plate 13 is arranged between the first gradual change plate 11 and the second gradual change plate 12; so that the first gradation plate body 11, the first constant variation plate body 13, and the second gradation plate body 12 are sequentially arranged along the first extending direction x1 and integrally formed.

Or, a first constant variable plate 13, a first gradual change plate 11, a first constant variable plate 13, a second gradual change plate 12 and a first constant variable plate 13 are sequentially arranged along the first direction; it can be seen that the first gradient plate 11, the second gradient plate 12 and the first constant gradient plate 13 can be flexibly set according to actual production requirements.
