DETAILED DESCRIPTION OF THE DRAWINGS
[0045] FIG. 1 shows three depictions of conditioning elements, in particular cooling elements 10, which extend along a longitudinal axis L, in section. On the left it is possible to see a channel element 12 having a substantially rectangular cross section. This forms a cooling channel 14. A structure is integrally formed onto the channel element 12 peripherally, in the present case fully peripherally. In the present case, the structure is in the form of an, in particular electrical, insulation layer 20. In the middle illustration, a conditioning element 10 comprises a plurality, in the present case in particular five, channel elements 12 which are arranged one above the other and which each form a cooling channel 14. In the right-hand half of the image, the conditioning element comprises three channel elements 12 of different shape which each form a cooling channel 14. In all cases, a or the structure is integrally formed directly onto the channel elements 12, wherein here in particular primary forming methods, such as injection molding, transfer molding or extrusion, should be mentioned as preferred.
[0046] FIG. 2 shows a further embodiment of a conditioning element 10, comprising a channel element 12 which comprises a cooling channel 14. The channel element 12, which for example has an oval or round shape, is peripherally provided intermittently along a longitudinal axis L with a structure, in the present case also in the form of an insulation layer 20. A structure configured in this way may be generated, for example, by way of encapsulation in the context of an extrusion method.
[0047] FIG. 3 shows a further schematic depiction of a conditioning element 10, comprising a channel element 12 together with a cooling channel 14. Structures are arranged or integrally formed in each case at the end of the channel element 12 and form contact elements or connecting elements 22. It can also be seen that the components 22 continue the cooling channel 14, which is formed substantially by the channel element 12, at the end. Moreover, the structure forms an insulation layer 20 around the channel element 12. The end-side components 22 are illustrated merely schematically in the present case. According to one embodiment, said components may, for example, be in the form of connections, which may be used as plug-in connections. In addition or as an alternative, a fastener, such as a thread or the like, may be provided on at least one of the components, etc.
[0048] FIG. 4 shows a schematic view of a tool 40, in which a channel element 12 is arranged. In the present case, a continuous process is depicted, in which the channel element 12 is displaced along a feed direction V in order for an insulation layer 20 to be integrally formed thereon, for example by way of extrusion.
[0049] FIG. 5 shows, as an alternative to the embodiment in FIG. 4, a tool comprising a lower tool half 42 and an upper tool half 44, which form a cavity (not shown here) by way of which a structure can be integrally formed onto a channel element 12, for example by way of injection molding or transfer molding.
[0050] FIG. 6 shows a further schematic view of a conditioning element 10, the latter comprising a plurality of channel elements 12 which as such have an identical length and are each of rectilinear form. Components 22 which are integrally formed in an appropriate manner make it possible to generate a conditioning element 10 having a meandering profile. For the purpose of electrical insulation, an insulation layer can be integrally formed onto the channel elements 12 (this is not illustrated in the present case).
