Definitions
- the present invention relates to a method for producing a turbulence device for receiving at least one flow channel of a heat exchanger of a motor vehicle with the following method steps:
- a first method step at least one substantially meander-shaped turbulence device is formed from a substantially endlessly flat sheet metal stiffener by means of at least one reshaping processing operation produced with substantially smooth walls, wherein a longitudinal direction of the walls is substantially parallel to a feed direction of the sheet metal stiffeners.
- wall sections are deformed at least at an angle ⁇ with respect to the feed direction such that undercuts with respect to the feed direction arise.
- the invention relates to a device for carrying out a method according to one of claims 1 to 10 with at least one roller set for successive forming of the sheet metal stiffener, in particular the sheet metal blank in a substantially meandering turbulence device with substantially smooth walls, with at least one device with embossing Rolling for deforming the wall sections at least at an angle ⁇ with respect to the feed direction such that undercuts with respect to the feed direction and at least one device for cutting the turbulence device to a predetermined length.
- the present invention further relates to a turbulence device produced by a method according to one of claims 1 to 10 and / or with a device according to one of claims 11 to 14.
- the charge air supplied to the engine is cooled as needed by means of a heat exchanger such as a charge air cooler. Further, a part of the recirculated exhaust gas, which is supplied again, for example, the charge air by means of a heat exchanger, such as an exhaust gas cooler cooled.
- a heat exchanger such as an exhaust gas cooler cooled.
- the charge air and / or the exhaust gas can also be cooled in a heat exchanger, which is a combination of a charge air cooler and an exhaust gas cooler.
- corrugated fins in particular internal corrugated fins
- the corrugated fins are introduced into the flow channels, in particular the tubes, such as pushed or shot.
- the ribs must be optimized so that on the one hand the heat exchanger performance achieved is increased and on the other hand, a pressure drop is minimized.
- a turbulence device is shown for example in unpublished DE 10 2007 014 138.8.
- the ribs essentially have a meander-shaped structure, wherein this meander-shaped structure is superimposed on a substantially wave-shaped structure in a plane offset by 90 °.
- impressions are introduced into the walls, so that flow passage openings can be formed. These impressions are introduced in a plane substantially perpendicular to the longitudinal direction of the turbulence device. In this way, undercuts occur in the direction of a plane which is substantially perpendicular to the longitudinal direction of the turbulence plane.
- a hollow chamber profile made of metal for heat exchanger is known.
- the hollow chamber profile has on the outside of cooling ribs which are deformed transversely to the longitudinal extent of the base profile.
- the cooling fins are shifted from those of the basic profile.
- a comb-like deformation tool is placed on the profile and at the same time all adjacent cooling fins are subjected to a corresponding deformation force.
- a folded multi-chamber flat tube is known. This is a self-contained profile, which has a greater strength than an open structure of a turbulence device, which is then inserted into a tube.
- the folded multi-chamber flat tube of DE 102 12 300 A1 is produced by means of a continuous production process, such as rotary die-cutting. Slits are cut or punched in a flat sheet metal strip. The punching of the breakthroughs takes place in time on a separate tool station before the supply of the smooth belt to the tube forming machine. Punching is thus carried out before the formation of the tube.
- a device for producing sheet metal parts for air conditioning ducts is known.
- a sheet metal strip is unwound from a coil and transferred in a continuous or quasi-continuous pass under stepwise deformation in a continuous rib.
- the trapezoidal profile is only smooth. Subsequently, a separation of the metal strip in a shaving unit and then only the beaded sheet metal strip is bent to a channel.
- turbulence devices such as inner corrugated fins
- a transverse rolling process Due to the limited length, such a process may require the manufacture of several short turbulence devices, which subsequently have to be individually introduced into the tubes of the heat exchangers. This results in equally high production times and production costs, in particular by the assembly.
- the processes have different cycle times, so that in particular the time-consuming punching process takes longer than the longitudinal rolling process for producing the precursor of the turbulence device with only smooth walls.
- the turbulence devices Due to the thin starting material, it is particularly difficult to cut the turbulence devices to a predetermined length of any arbitrary length, since the areas in which they intersect through the turbulence device must be precisely fixed to obtain an exact cut substantially without burrs, as the burrs would lower the heat transfer efficiency and increase the pressure loss. Such a cutting should be able to take place at any point of the turbulence device. Due to the complex structure of the turbulence device with undercuts and dislocations, this cutting operation is problematic.
- An inventive method for producing a turbulence device for receiving in at least one flow channel of a heat exchanger, in particular a charge air cooler and / or an exhaust gas cooler, a motor vehicle is provided.
- the method has the following method steps:
- At least one essentially meander-shaped turbulence device with essentially smooth walls is produced from a substantially endless flat sheet metal stiffener by means of at least one forming machining operation, wherein a longitudinal direction of the walls runs essentially parallel to a feed direction of the sheet metal stiffener.
- the wall sections at least at an angle ⁇ relative to the feed direction deformed such that undercuts with respect to the feed direction arise. Cutting to length of the substantially endless sheet metal stiffener in turbulence devices of predefined length takes place before the second method step is carried out.
- the cutting to length is carried out before the first process step.
- the length of the turbulence device can be generated even before the formation of the meander-shaped structure.
- the die fixation for a precise cut can be made particularly advantageous in this way.
- the cutting to length is carried out between the first method step and the second method step. In this way, the cutting takes place as late as possible, so that subsequent deformation operations no longer have any effect on the cut edge and in this way particularly advantageous inaccuracies can be avoided.
- At least one cut is made in the meander-shaped turbulence device before the wall sections are deformed.
- the cut is introduced at an angle ⁇ .
- the angle ⁇ affects the course of the cutting edge of the undercuts with respect to the rolling direction.
- deformations in the turbulence device can be introduced in a particularly advantageous manner, such as, for example, openings for flowing through a fluid flow in which turbulence is generated, for example charge air and / or exhaust gas or a coolant, such as air.
- the turbulence of the fluid and in particular thus the heat transfer increases at a reasonable increase in the pressure loss.
- the angle ⁇ and / or the angle ⁇ assumes values of 0 ° to 90 °, in particular of 0.5 ° to 80 °.
- the first method step is a rolling method, in particular a longitudinal rolling method.
- turbulence devices, in particular ribs can be produced with an arbitrarily predetermined length.
- the first method step comprises 2 to 40 intermediate steps, in particular 2 to 35 intermediate steps, in particular 2 to 30 intermediate steps, and comprises these.
- the sheet metal stiffener is processed successively such that the width of the thus produced substantially smooth turbulence device has a smaller turbulence device width than in the preceding intermediate step.
- the sheet metal stiffeners are processed so gently, in particular reshaped, so that gradually the meandering structure is formed and the sheet thickness of the entire turbulence device generated is substantially equal, so that there are no unwanted cracks and material thinning in particular.
