Definitions

  • the invention relates to a heat exchanger having the features in the preamble of claim 1.
  • Heat exchangers of this type are state of the art, cf. DE 20 208 748 U1 , With air as the cooling medium, such heat exchangers are often used for cooling hydraulic fluids for the working hydraulics of mechanical systems, such as construction machinery. Like., For hydrostatic travel drives or as oil cooler for high-loaded transmission, especially in wind turbines. In the operation of such systems, the heat exchangers are exposed not only to mechanical stresses, but because of the high operating temperature of the fluids to be cooled, in particular thermal loads. This is particularly the case when intermittent operations result in temperature jumps, resulting in excessive stresses in the package of components due to material strains, which are connected to a rigid block by soldering. The result is stress cracks, especially in the area of the solder joints, with the risk of failure of the heat exchanger and thus the threat to the associated system.
  • the invention has for its object to provide a heat exchanger available, which is characterized by a improved resistance to operating loads, so that a safe long-term operation is possible.
  • the DE3521914 discloses a heat exchanger, in particular for fluid cooling devices, with a package of plane-parallel plates, wherein between pairs of superimposed plates in alternation fürström Kunststoffe for a hot medium and for a cooling medium are formed, which are bounded laterally by the respective plates at a distance holding profile strips on the Form plates adjacent solder surfaces, wherein the profile strips at the flow areas of a medium and the other medium along an angle abutting edges of the plates, wherein at least the moldings of the flow areas of the cooling medium comprises a base body, two of this along the solder surfaces extending leg and between these have an open to the adjacent flow area recess, and wherein the recess is limited at least in the adjoining at its inner end portion region of planar wall parts. According to the invention this object is achieved by a heat exchanger having the features of claim 1 in its entirety.
  • a significant feature of the invention is that the recess, starting from its inner end portion, divergent first planar wall portions extending to narrow points of the cross section of the legs, adjoining the bottlenecks, converging second planar wall parts and adjoining third planar wall parts which, parallel to the soldering surfaces, extend in the vicinity of the opening of the recess.
  • zones of lower flexural strength are formed on the profile legs, to which leg sections on both sides connect in which the bending resistance increases substantially linearly.
  • the bottlenecks not only define a bending line of a kind of bending joint, but also represent the location of the steepest temperature gradient. Since this is effective at the location of the smallest material cross-section, resulting correspondingly low material expansions and stresses.
  • the shape of the cross-section adjoining the soldering surfaces of the legs is optimized with regard to the avoidance of excessive stresses by special shaping of the recess, at least in the case of the profile strips adjoining the cooling medium.
  • the recess starting from the inner end portion having planar wall parts, an at least approximately linear change in the bending strength over the length of the profile legs can be achieved, so that by selecting the length and / or inclination of these planar wall parts relative to the Lötzine an optimal Bending behavior of the legs is achievable.
  • the recess is shaped in such a way that adjoin the third planar wall parts fourth planar wall parts which extend slightly divergent to the opening of the recess to each other.
  • the first planar wall portions may form mutually perpendicular planes, and the second planar wall portions may include an obtuse angle with the first planar wall portions, which is preferably only slightly greater than a right angle.
  • the cross-sectional shape of the recess in the region adjacent to the inner end corresponds approximately to a square open towards the opening.
  • the arrangement can be made such that the first planar wall parts are connected to each other and these with the second planar wall parts each over curved wall locations with the same radius of curvature.
  • the second planar wall parts are connected to the third planar wall parts and these with the fourth planar wall parts preferably also each curved over wall locations with the same, second radius of curvature, which is twice the first radius of curvature.
  • the arrangement is preferably made so that the thickness of the cross section of the legs in the region of the third planar wall parts is approximately twice the thickness of the cross section at the bottlenecks.
  • the Fig.1 illustrates an embodiment in the form of a conventional plate-type heat exchanger with a stack of flat plates 1, preferably made of an aluminum alloy, which run in parallel planes and separating plates for flow areas located between them form, between each successive plate pairs in alternation in each case a flow area 3 for the medium to be cooled, for example, hydraulic oil, and a flow area 5 for a cooling medium, such as cooling air, are formed.
  • a flow area 3 for the medium to be cooled for example, hydraulic oil
  • a flow area 5 for a cooling medium such as cooling air
  • the für Hopkins Society 5 of the cooling medium is laterally also each bounded by end strips, which form the spacers between the respective plate pair and which are formed as profiled strips 11 with special, inventive design.
  • This embodiment of the invention is based on the Fig.2 explained in more detail.
  • the profile strips 11, which are also preferably extruded from an aluminum alloy, have a cuboid or block-shaped basic body 13 which faces the edge region of the plates 1, a recess 15 in the form of a continuous longitudinal groove and the recess 15 limbs 17 bordering on both sides.
  • the recess 15 is open to the flow area 5, in which there are cooling fins 19, which, as well as the turbulators 9 in the flow area 3, increase the effective heat transfer area.
  • the inner end portion 23 ( Fig.2 ) of the recess 15 is located from the closed end 21 of the profile strip 11 at a distance which is slightly greater than the distance between the end portion 23 and opening of the recess 15.
  • the recess 15 is, starting from its inner end portion 23, bounded by planar wall portions 29 which, diverging to each other and enclosing a right angle, extend into the vicinity of the relevant soldering surface 25 and form there a Profilengstelle 31 of the profile cross section of the legs 17.
  • the constriction 31 is adjoined by second planar wall parts 33, which converge toward one another and enclose an obtuse angle with the first planar wall parts 29, which angle is slightly larger than a right angle.
  • the length of these second planar wall portions 33 is slightly smaller than the length of the first planar wall portions 29, and these third planar wall portions 33 are followed by third planar wall portions 35 defining planes parallel to the soldering surfaces 25 and extending into the vicinity of the opening the recess 15 extend. At this third planar wall portions 35 in turn close fourth planar wall portions 37 which extend slightly divergent to the opening of the recess 15 to each other.
  • the connection of the first planar wall portions 29 with each other and with the second planar wall portions 33 takes place in each case via curved wall portions 39 with the same radius of curvature.
  • the connection of the second planar wall portions 33 with the third planar wall portions 35 and this with the fourth planar wall portions 37 also takes place over curved wall portions 41, in which the radius of curvature is twice the radius of curvature at the wall portions 39.
  • the inventively provided cross-sectional shape of the recess 15 results in an effective reduction of the operational stress peaks and the risk of cracking at the solder joints.
  • the bottlenecks 31 on the leg profile form the location of the steepest temperature gradient.
  • this is also the location of the smallest material cross-section, so that thermal deformations are limited to correspondingly limited material parts. Since the profile thickness of the legs 17, starting from the constrictions 31, increases towards the opening to a profile thickness which corresponds approximately to twice the constrictions 31, an optimum stress distribution over the area of the soldering surfaces 25 results.
  • the heat exchanger device according to the invention need not be limited to the field of fluid cooling, but can also be used generally for the cooling of gaseous media and here in particular intercooler (diesel engines), as well as secondary and intercooler (compressors) to include.
  • intercooler diesel engines
  • secondary and intercooler compressors
  • the temperature differences (cooling air to medium) in the pertinent applications are comparatively much higher than described above.
