The turbulence insert (24) has a number of sections (41-45) with corrugated profiles that extend in the same direction of the extension of the corrugations and which, perpendicular to the direction of the extension of the corrugations, are offset from one another. In order to enable a better thermodynamic efficiency, the turbulence insert (24) has a number of sections (27-32, 41, 45) with corrugated profiles extending in different directions of extension of the corrugations.
Description
- The invention relates to a one-piece turbulence insert for a heat exchanger, in particular an automotive cooler, having a substantially corrugated profile, the turbulence insert comprising a plurality of sections with corrugation profiles which propagate in the same direction of propagation and are offset to one another transversely to the direction of propagation.
- Conventional turbulence inserts are produced using rolls. An oil/coolant cooler consisting of a plurality of plates arranged in parallel one above the other is known from German patent DE 197 09 601 C2. Each of the plates has on two opposed edges a respective inlet and outlet opening for a heat exchange medium. The plates form between them hollow chambers in which corrugated sheet-metal turbulence panels are provided to increase the heat transfer, each of the media used for heat transfer flowing through alternate chambers. The sheet-metal turbulence panels are subdivided into sections in which the corrugations are oriented differently. The sections are divided from one another by oblique separation cuts. The sheet-metal turbulence panels are rolled, the direction of rolling in adjacent sections being rotated through a predefinable angle with respect to the direction in the adjacent section. The respective inlet and outlet openings of each of the heat exchange media are so arranged in the sections that a flow from the inlet opening encounters greater resistance directly in the direction of the outlet opening than in a direction transverse thereto, so that a uniform distribution of flow in the associated hollow chamber is produced. The known sheet-metal turbulence panels are composed of a plurality of rolled parts in order to produce sections having different directions of propagation of the corrugations. Gate-like openings are produced transversely to the rolling direction, which openings have different widths in adjacent rows so that slot-like openings are formed in known fashion between adjacent gates, making possible not only a transverse flow through the gates but also a flow in a direction perpendicular thereto.
- It is the object of the invention to provide a one-piece turbulence insert for a heat exchanger, in particular an automotive cooler, having a substantially corrugated profile, which turbulence insert comprises a plurality of sections having corrugation profiles that propagate in the same direction of propagation and are offset to one another transversely to the direction of propagation, which turbulence insert makes possible improved thermodynamic efficiency.
- This object is achieved with a one-piece turbulence insert for a heat exchanger, in particular an automotive cooler, which has a substantially corrugated profile and comprising a plurality of sections with corrugation profiles which propagate in the same direction of propagation and are offset to one other transversely to the direction of propagation, in that the turbulence insert comprises a plurality of sections which have corrugation profiles propagating in different directions of propagation. The turbulence insert according to the invention makes possible a specified distribution of a medium within a flow channel and/or a specified stiffening of a heat exchanger under locally varying load states according to the local load tensors, and/or optimization of thermodynamic performance by a suitably formed rib structure in some or all of the flow channels of a heat exchanger. The turbulence insert according to the invention is formed either as a whole or in segments, using a combined punching and deep-drawing process. The structure of the turbulence insert may also be in the form of a closed structure. In that case the punching process may be omitted.
- A preferred embodiment of the turbulence insert is characterized in that the turbulence insert comprises a plurality of rectangular sections having corrugation profiles propagating in different directions of propagation. Flow through a flow channel in different directions is thereby made possible.
- A further preferred embodiment of the turbulence insert is characterized in that the turbulence insert is formed from a substantially rectangular plate which comprises a central portion having a plurality of sections with corrugation profiles propagating transversely to the longitudinal direction of the plate, and two outer portions having a plurality of sections with corrugation profiles propagating at an angle from 0 to 90 degrees with respect to a longitudinal side of the plate. The outer portions are preferably arranged at a medium inlet and a medium outlet. For this reason the outer portions are also referred to as inlet and outlet portions. The flow at the inlet and the outlet preferably takes place transversely to the longitudinal direction of the plate. The inventive configuration of the inlet and outlet portions makes possible a flow between the inlet and outlet portions and the central portion which is optimized fluidically and thermally.
- A further preferred embodiment of the turbulence insert is characterized in that the corrugation profiles in the sections of the outer portions arranged closer to the central portion propagate at a larger angle with respect to a longitudinal side of the plate than in the sections arranged further towards the outside. At the ends of the plate the corrugation profiles are preferably disposed at an angle from 50 to 80 degrees to the associated longitudinal side of the plate. In the vicinity of the central portion the corrugation profiles are preferably disposed at an angle from 10 to 40 degrees to the associated longitudinal side of the plate. This makes possible a gentle deflection of the flow from the longitudinal side of the plate towards the central portion.
- A further preferred embodiment of the turbulence insert is characterized in that the angle with respect to a longitudinal side of the plate at which the corrugation profiles propagate in the outer portions of the plate decreases from the central portion towards the outside. This makes possible a gentle deflection of the flow from the longitudinal side of the plate towards the central portion.
- A further preferred embodiment of the turbulence insert is characterized in that the turbulence insert is formed by a substantially rectangular plate which comprises a central portion having a plurality of sections with corrugation profiles which propagate transversely to the longitudinal direction of the plate, and two outer portions having a plurality of sections with corrugation profiles which propagate in the longitudinal direction of the plate. Gate-like openings which have different widths in adjacent portions are formed transversely to the longitudinal orientation of the corrugations, so that slot-like openings are produced between respective adjacent gates, making possible a flow which passes not only transversely through the gates but also in a direction perpendicular thereto.
- A further preferred embodiment of the turbulence insert is characterized in that deflection sections are formed between the corrugated profile sections which propagate transversely and longitudinally. The flow is deflected through 90 degrees in the deflection sections.
- A further preferred embodiment of the turbulence insert is characterized in that the deflection sections are arranged diagonally in the outer portions of the plate. The formation of dead-water zones is thereby reduced.
- A further preferred embodiment of the turbulence insert is characterized in that the direction of propagation of the corrugations changes by 90 degrees in the deflection sections. The transition zone preferably has a rounded configuration.
- In an automotive cooler, in particular an exhaust gas cooler of a commercial vehicle, the object specified above is achieved by the use of a turbulence insert as described hereinbefore.
- Further advantages, features and details of the invention are apparent from the following description, in which diffferent embodiments are described in detail with reference to the drawings. Each of the features mentioned in the claims and in the description can be essential to the invention in isolation or in any combination. In the drawings:
