Abstract

Claims (40)

1 . A device for regulating a temperature of cylindrical components, the device comprising an elongate base profile having a first main surface and a second main surface, each of which, when viewed in a longitudinal direction, extends between two longitudinal ends of the elongate base profile and, when viewed in a transverse direction, extends between two side surfaces,

wherein the elongate base profile defines in an interior of the elongate base profile a plurality of fluid flow channels, the plurality of fluid flow channels comprising at least two fluid flow channels, which each run from one longitudinal end of the elongate base profile to another longitudinal end of the elongate base profile,

wherein the plurality of fluid flow channels are arranged in series in the transverse direction and are defined by the first main surface, the second main surface, the two side surfaces, and webs, wherein the webs delimit individual fluid flow channels from one another,

wherein the first and second main surfaces each have an alternating sequence of concave regions and straight regions, wherein at least one concave region of the first main surface, when viewed in a thickness direction of the elongate base profile, which runs both orthogonally to the longitudinal direction and orthogonally to the transverse direction, is at least in part superposed by at least one straight region of the second main surface,

wherein at least one of the straight regions substantially defines a plane which extends in the longitudinal direction and the transverse direction, and

wherein the straight regions of the first and second main surfaces have normal vectors that extend parallel to the thickness direction of the elongate base profile of the device.

2 . The device according to claim 1 ,

wherein superposition of the at least one concave region of the first main surface with the at least one straight region of the second main surface is designed symmetrically.

3 . The device according to claim 1 ,

wherein the elongate base profile is produced from plastic by extrusion.

4 . The device according to claim 1 ,

wherein a material from which the elongate base profile is made comprises polyketones and/or polyamide.

5 . The device according to claim 1 ,

wherein the device comprises a first connection portion at a first of the two longitudinal ends and a second connection portion at a second of the two longitudinal ends, where the first and second connection portions are configured to introduce fluid flowing into the first and/or second connection portions into the elongate base profile or to discharge fluid coming from the elongate base profile out of the first and/or second connection portions.

6 . The device according to claim 5 ,

wherein the first and second connection portions are non-detachably connected to the respective longitudinal end of the elongate base profile in a fluid-tight manner.

7 . The device according to claim 5 ,

wherein each of the first and second connection portions has an inlet, an outlet and a branch opening, and where each of the first and second connection portions is fluidically connected to the elongate base profile at the respective branch opening.

8 . The device according to claim 7 , wherein the device is a first device,

wherein the first connection portion of the first device is designed to fit a first connection portion of a second device, and wherein the second connection portion of the first device is designed to fit a second connection portion of the second device, such that the inlet of the first connection portion of the first device can be connected in a fluid-tight manner to an outlet of the first connection portion of the second device, and the outlet of the second connection portion of the device can be connected in a fluid-tight manner to an inlet of the second connection portion of the second device.

9 . The device according to claim 8 ,

wherein the inlet of the first connection portion of the device and the outlet of the first connection portion of the second device are configured to latch together, such that an unintentional disengagement of the inlet of the first connection portion of the device from the outlet of the first connection portion of the second device can be prevented.

10 . The device according to claim 1 , wherein at least one of the longitudinal ends of the elongate base profile is widened, so that a flow cross-section of each fluid flow channel of the plurality of fluid flow channels is enlarged.

11 . A cooling system, comprising at least two devices according to claim 1 ,

wherein each of the at least two devices comprises a first connection portion connected to a first of the two longitudinal ends and a second connection portion connected to a second of the two longitudinal ends of the respective elongate base profile,

wherein a first device of the at least two devices is connected to a second device of the at least two devices in such a manner that an outlet of the first connection portion of the first device is connected in a fluid-tight manner to an inlet of the first connection portion of the second device and/or an inlet of the second connection portion of the first device is connected in a fluid-tight manner to an outlet of the second connection portion of the second device.

12 . The cooling system according to claim 11 ,

wherein an intermediate piece is arranged between the outlet of the first connection portion of the first device and the inlet of the first connection portion of the second device and/or an intermediate piece is arranged between the inlet of the second connection portion of the first device and the outlet of the second connection portion of the second device, the intermediate piece(s) extending a fluid channel formed by the respective outlet and the respective inlet in such a manner that a distance between the elongate base profiles of the at least two devices is increased.

13 . The cooling system according to claim 11 ,

wherein the elongate base profile of the first device is arranged mirrored with respect to an elongate base profile of the second device, that is, a concave region of the elongate base profile of the first device is directly opposite a concave region of the elongate base profile of the second device, or a straight region of the elongate base profile of the first device is directly opposite a straight region of the elongate base profile of the second device.

14 . Method for producing a device for regulating a temperature of cylindrical components, wherein the method comprises the steps of:

a) extruding an elongate base profile made of plastic, which has a first main surface and a second main surface, each of which, when viewed in a longitudinal direction, extends between two longitudinal ends of the elongate base profile and, when viewed in a transverse direction, extend between two side surfaces,

wherein the elongate base profile defines in an interior of the elongate base profile a plurality of fluid flow channels, the plurality of fluid flow channels comprising at least two fluid flow channels, which each extend from one longitudinal end of the base elongate profile to another longitudinal end of the elongate base profile, wherein the plurality of fluid flow channels are arranged in series in the transverse direction and are defined by the first main surface, the second main surface, the two side surfaces, and webs, wherein the webs delimit individual fluid flow channels from one another;

b) deforming the elongate base profile by a thermoforming method in such a manner that the first and second main surfaces each have an alternating sequence of concave regions and straight regions,
