Abstract
Disclosed is a device for regulating the temperature of cylindrical components and a cooling system including at least two devices for regulating the temperature of cylindrical components. The device includes an elongate base profile that defines in its interior a plurality of at least two fluid flow channels arranged in series in the transverse direction and are separated by webs. The elongate base profile has main surfaces that each have an alternating sequence of concave regions and straight regions.

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.
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,
- wherein a concave region of the first main surface, when viewed in a thickness direction of the elongate base profile, which extends both orthogonally to the longitudinal direction and orthogonally to the transverse direction, is at least in part superposed by a 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;
- c) connecting a first of the two longitudinal ends of the elongate base profile with a first connection portion and connecting a second of the two longitudinal ends of the elongate base profile with a second connection portion in order to produce a first device;
- d) repeating steps a) to c) to produce a second device;
- and
- e) connecting the first device to the second device in such a manner that an outlet of the first connection portion of the first device is fluid-tightly connected 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 fluid-tightly connected to an outlet of the second connection portion of the second device.
