- a pipe in particular for Recording of functional elements, such as PTC heating elements, as well Uses of such a pipe.
- Electric heaters in which for generating a Heating power Resistance heating elements in the form of PTC elements are used today, are on many different Areas of technology, for example in the automotive industry, known.
- the said heating devices for example used for heating vehicle interiors, as long as alternative heating methods using the engine cooling water as heating medium due to insufficient engine heating not yet working efficiently.
- the electric heater can be carried out both separately as well as in a flowed through by the cooling water ribs / tube block be integrated by, for example, a Part of the cooling water-carrying pipes replaced by PTC pipes is.
- regular individual PTC elements in hollow receptacles such as Profile tubes arranged to clamp the PTC elements by applying pressure to their top walls plastically be deformed.
- the said heaters additionally to the heating tubes described above (receiving means and PTC elements) regularly heat release ribs in the form of fins or the like, which conducts heat well connected to the heating pipes.
- the lamellar assembly must be installed in a downstream, take additional process step, so that in disadvantageously long production times and corresponding Cost increases result.
- the invention is based on the object, a method and specify a profile tube with which the above enumerated Overcome disadvantages.
- the object is achieved by a method for clamping of functional elements, in particular PTC heating elements, in a hollow receiving means, like a pipe, with two each other and flat sides of the functional elements opposite, at least partially concave top wall areas, wherein the functional elements by pressurizing the substantially perpendicular to the concave top wall areas extending side walls are braced.
- the Task is also solved by a pipe, in particular for receiving functional elements, such as PTC heating elements, with two each other and flat sides of the Functional elements opposite, at least partially concave top wall areas as well as in essence perpendicular to the concave top wall areas extending further side walls, which reduce the light Distance between the retracted top wall areas with a compression pressure can be acted upon.

- pressurization essentially in the direction of Surface normal of the side walls takes place, in particular, that the forces exerting the pressure a predominant or main component parallel to the surface normal the side walls have, albeit the forces are not directed exactly parallel to the surface normal.
- the bracing takes place the functional elements preferably such that by the pressurization a clear distance between the opposite top walls is reduced, wherein areas of the concave top wall areas to pinch approximate the functional elements to each other.
- a distance between sections each at least one concave top wall area reduced and between these at least one Attachment part, such as a metal lamella or -Wellrippe permanently is trapped. It is possible in this way, that Fixing attachment parts to integrate in the pressing process.
- the profile tube according to the invention In development of the profile tube according to the invention is provided that through cover walls of the retracted top wall areas before pressurization, an outward expanding free space with essentially one Isosceles trapezoid defined corresponding cross section is.
- the free space is preferably for recording at least one complementary end region at least a lug, such as a metal lamella or -Well rib, trained.
- the profile tube according to the invention is the attachment part after pressurization by the cover walls the concave top wall area substantially positive fit surrounded and held in this way clamped.
- the neck parts can continue to be provided be that the top walls of the retracted top wall areas after pressure undercuts for receiving complementary corner regions of the attachment part define. Due to the low required Press forces can be further differentiated from the state of the Technique also processed longitudinally ribbed profiles be so far regularly in a complex manner two separate half-profiles were built.
- Corresponding has the profile tube according to the invention in a preferred Training in at least one of the cover or side wall areas Rib elements, preferably a Extension component in the longitudinal direction of the profile tube exhibit.
- the rib elements In addition, an extension essentially in cross section perpendicular to a local course of the deck and / or Sidewall areas or the top and / or side walls exhibit.
- the profile tubes described above are generally suitable to provide a composite device a number of profile tubes and these connecting attachment parts, the neck portions through the profile tubes are held, and preferably take in a radiator an arrangement of heat-emitting fins use.
- Fig. 1 shows an extruded, inventive Profile tube 1 with a substantially rectangular cross-section.

- the profile tube 1 has top wall areas 1.2, 1.3 on, compared to a strictly rectangular Cross section of the profile tube 1 retracted inward are, i. show a concave training.
- Top wall areas 1.2, 1.3 of the profile tube 1 are defines outward expanding free space areas 1.4, of which in Fig. 1 by way of example only one dashed is shown.
- the cover walls 1.5, 1.6 of the profile tube 1 have in the retracted, concave top wall areas 1.2, 1.3 an inner distance a, the larger is a corresponding dimension a 'between the flat sides 2a, 2b of the PTC element 2.
- Profile tube 1 more side walls or side wall areas 1.7, 1.8, which are substantially perpendicular to the concave top wall areas 1.2, 1.3 extend and their clear distance b is greater than a corresponding dimension b 'of PTC element 2, where: (b-b')> (a-a ').
- the inventive Profile tube 1 also along its outer Contour rib members 3, which are perpendicular to the plane of the drawing, i.e. extend in the profile longitudinal direction and thereby in cross-section substantially perpendicular to a local Extension direction of the top and side walls 1.5-1.8 aligned are.
- FIGS. 2a, b show a further possible embodiment of the profile tube 1 according to the invention, here first (Fig. 2a) as a seamless drawn or welded tube with circular Cross-section, which, as shown in Fig. 2b, for training concave top wall sections 1.2, 1.3 (see Fig. 1) is to profile accordingly, for example, using a suitable roller system (not shown here).
- Figs. 3a, b show in detail the already mentioned Pressing process by pressurization (arrows P) the side walls 1.7, 1.8 of the profile tube according to the invention 1.
