Furthermore, the corrugation extending directions of the two groups of inclined corrugated plates are the same and the inclined corrugated plates are arranged in a turnover parallel mode.

Further, the adjacent plate groups are arranged in parallel in an overturning manner.

Furthermore, the oblique corrugations of the two oblique corrugated plates form a herringbone wave; the wave depth of the oblique waves is 0.7-0.9mm, the wave pitch is 3.3-3.5mm, and the thickness is 0.17-0.33 mm.

Furthermore, the wave crests and the wave troughs of the oblique corrugations are planar.

Further, the oblique corrugated plate is made of a single plate.

Furthermore, the edge of the inclined corrugated plate is in a plate shape.

Further, the main body of the oblique corrugated plate is a rectangular plate; the thickness of the long edge strip is 0.7-0.9mm, and the long edge strip is attached to the edge of the long edge of the inclined corrugated plate; the thickness of the short edge strip is 0.35-0.45mm, and the short edge strip is attached to the edge of the short edge of the inclined corrugated plate.
