DETAILED DESCRIPTION

[0032] In FIG. 1, a tubular body arrangement 1 for a temperature-control device 2 according to the invention is exemplarily shown in a longitudinal section along an axial direction A. The temperature-control device 2 can be employed for temperature-controlling an electrical device 3. The tubular body arrangement 1 comprises at least one first tubular body 4 and at least one second tubular body 5, which are equipped for being flowed through by a temperature-control fluid F. Said temperature-control fluid F can be a gas or a liquid. Each of the tubular bodies 4, 5 comprises a circumferential wall 6, which extends along the axial direction A. The axial direction A extends along a centre longitudinal axis M of the first tubular body 4. Perpendicularly to the axial direction A, a radial direction R extends away from the centre longitudinal axis M. A circumferential direction U extends perpendicularly to the radial direction R and perpendicularly to the axial direction A and circulates about the centre longitudinal axis M. For compensating for a position change and/or a dimensional change of an axial length L measured along the axial direction A of at least one of the tubular bodies 4, 5, a deformable first tube flange 7 projecting from its circumferential wall 6 at an angle is present on the first tubular body 4. The first tube flange 7 of the first tubular body 4 is deformable for accommodating the length change of the axial length L measured along the axial direction A of at least one of the tubular bodies 4, 5 or the position change of one of the tubular bodies 4, 5. By means of the deformation of the first tube flange 7 of the first tubular body 4, the position change and/or dimensional change of at least one of the tubular bodies 4, 5 can be compensated for. Such a position change and/or dimensional change can materialise for example as a consequence of a temperature expansion of at least one of the tubular bodies 4, 5. Facing away from the circumferential wall 6 of the first tubular body 4, the second tubular body 5 is mounted to the first tube flange 7 of the first tubular body 4. Tubular body arrangement 1 can be formed without any additional sealing element or gasket.

[0033] The second tubular body 5 can be mounted to the tube flange 7 of the first tubular body 4 in a firmly bonded manner. The second tubular body 5 can be welded or glued to the first tube flange 7 of the first tubular body 4. Here, the second tubular body 5 is mounted to the first tube flange 7 of the first tubular body 4 in such a manner that the two tubular bodies 4, 5 jointly bound a tubular body interior 8 that can be flowed through by the temperature-control fluid F. On the first tube flange 7 of the first tubular body 4 a thin area 9 can be present. In the thin area 9 of the first tube flange 7 of the first tubular body 4, a flange thickness 10 of the first tube flange 7 is reduced compared with a wall thickness 11 of the circumferential wall 6 of the first tubular body 4. The flange thickness 10 of the first tube flange 7 can be reduced relative to the wall thickness 11 of the circumferential wall 6 of the first tubular body 4 in such a manner that a predetermined deformation area 12 is created by the thin area 9. The thin area 9 can be circumferentially formed, in particular completely, along the circumferential direction U. On the second tubular body 5, a second tube flange 13 can be present on the first tube flange 7 of the first tubular body 4 for fastening the second tubular body 5. The second tube flange 13 can be formed projecting from the circumferential wall 6 of the second tubular body 5 at an angle. The second tube flange 13 of the second tubular body 5 can project, perpendicularly to the circumferential wall 6 of the second tubular body 5, along the radial direction R to the outside.

[0034] The first tube flange 7 of the first tubular body 4 can be mounted lying against the second tube flange 13 of the second tubular body 5. To this end, a welding geometry can be present on the first tube flange 7 of the first tubular body 4 andalternatively or additionallyon the second tube flange 13 of the second tubular body 5, by means of which the first tubular body 4 and the second tubular body 5 can be welded to one another. The welding geometry can be designed for connecting the first tubular body 4 to the second tubular body 5 by means of an ultrasound welding method.

[0035] In the tubular body arrangement 1, the circumferential wall 6 of the first tubular body 4 and the circumferential wall 6 of the second tubular body 5 can be arranged along the axial direction A relative to one another at an axial deformation distance 14 measured along the axial direction A. Here, the first tubular body 4 and the second tubular body 5 can be arranged at the axial deformation compensation distance 14 relative to one another so that between the tube flanges 7, 13 a circumferential deformation compensation space 15 is formed.

[0036] On the second tube flange 13 of the second tubular body 5, a continuation 16, directed in the axial direction A towards the first tubular body 4, can be arranged. The continuation 16 can be formed circumferentially projecting from the second tube flange 13 along the circumferential direction U. The continuation 16, seen in the radial direction, can be arranged between the deformation compensation space 15 and the tubular body interior 8. Alternatively or additionallywhich for the sake of clarity however is not shown in the figuresa continuation 16 can be axially arranged on the first tube flange 7 of the first tubular body 4 in the direction of the second tubular body 5. This continuation 16 arranged on the first tube flange 7 can be formed circumferentially along the circumferential direction. The continuation 16 that is present on the first tube flange 7 can be arranged, seen in the radial direction, between the deformation compensation space 15 and the tubular body interior 8.

[0037] The first tube flange 7 of the first tubular body 4 can comprise a rounded region 17. In the rounded region 17 of the first tube flange 7 of the first tubular body 4, the first tube flange 7 can merge, at a first end of the circumferential wall 6 of the first tubular body 4 facing the first tube flange 7, into the circumferential wall 6. In the rounded region 17 of the first tube flange 7, the thin area 9 of the first tube flange 7 can be formed. The rounded region 17 with the thin area 9 of the first tube flange 7 can be formed circumferentially along the circumferential direction U. On the first tubular body 4, a second tube flange 13 can be present at a second end 19 of the first tubular body 4 facing away from the first tube flange 7 of the first tubular body 4. This second tube flange 13 of the first tubular body 4 can be formed in the same manner as the second tube flange 13 of the second tubular body 5. At the first end 18 of the second tubular body 5 facing away from the second tube flange 13 of the second tubular body 5, the second tubular body 5 can comprise a first tube flange 7. This first tube flange 7 of the second tubular body can be formed in the same manner as the first tube flange 7 of the first tubular body 4. The first and the second tubular body 4, 5 can be formed as identical parts.

[0038] In the circumferential wall 6 of the first and second tubular body 4, 5, an opening 21 can be present, which radially penetrates the circumferential wall 6 of the respective tubular body 4, 5. The temperature-control fluid F flowing through the tubular body interior 8 can be conducted out of the tubular body interior 8 or conducted into the tubular body interior 8 through this opening 21 radially penetrating the circumferential wall 6 of the respective tubular body 4, 5. The circumferential wall 6 of the first and of the second tubular body 4, 5 can additionally comprise a bellows-like or corrugated tube-like deformation compensation portion which however is not shown in FIG. 1. Likewise not shown is that the tubular body arrangement 1 can comprise a third tubular body having such a bellows-like or corrugated tube-like portion.
