Element 1 comprises the multiple fin 25 extended from body 2; Especially, described element comprises at least the first group 26 of fin 25, and first group of described fin extends from sidepiece 9 and specifically extend from the side surface 10 of described sidepiece 9, and is all arranged on a side of the central plane P of element 1; Preferably, element 1 comprises two groups 26 of relative fin 25, and two groups of described relative fin extend from corresponding sidepiece 9 and specifically extend from the respective side surface 10 of sidepiece 9, and are arranged on the opposite side of plane P.

Described is below the group 26 of the fin 25 carried by sidepiece 9; Other groups (selectively existing) of fin 25 advantageously have identical with the group described in fin or similar structure and layout, and preferably symmetrical relative to the group described in fin; Still be appreciated that described two groups 26 also can be included in the different fin 25 in the shape of fin, size and/or layout aspect in any case.

The group 26 of fin 25 is along sidepiece 9 and substantially extend in a longitudinal direction along the respective axis A being basically parallel to axis X.Fin 25 is aimed at along axis A substantially parallel accordingly and is separated by corresponding series of grooves 28.

Fin 25 selectively (but be not must) is arranged parallel to each other and the row 27 of the X that parallels to the axis; That is, multiple fin 25 is expert in 27 and is aimed at.In the limiting examples shown in Fig. 1, group 26 comprises the fin 25 of at least two (and be preferably at least three) adjacent lines 27, and described fin to be aimed at and by corresponding series of grooves 28 separately along the substantially parallel to each other and respective axis A being parallel to main shaft X; Described row 27 is adjacent on the direction transverse to axis A, that is, directly in succession, between described row, do not arrange any other fin.

In the limiting examples shown in Fig. 1, Fig. 2, fin 25 is shapes of quadrangle generally, selectively has the edge of bending edge and/or circle; The shape of groove 28 is substantially as the gap (slit) be arranged between two fin 25 in succession.

Element 1 also can have the fin with sweep, as shown in the top of Fig. 1: subsequently, is appreciated that at least one expandable part (stretch) that the whole fin 25 be included in described group 26 have the axis A along the X that parallels to the axis and extend.

But, more generally, each fin 25 has two relative faces 31, such as, described relative face is basic plane and parallel, and each fin by be fixed on sidepiece 9 root edges 32, by the free end edge 33 relative with root edge 32 and be respectively bottom by two relative sides 34,34'(with top) define, described root edges extends from the side surface 10 of sidepiece 9, and described two relative sides connect edge 32,33.Edge 32,33 can be basic straight line or bend, and/or has round edge; Edge 32,33 can be substantially parallel to each other or not parallel, etc.Similarly, edge 34,34' can be basic straight lines or bend, and/or have round edge; Edge 34,34' can substantially parallel to each other or converge or fork, etc.
