Definitions

  • the present invention relates to a heat exchanger with tubes and interposed corrugated fins with straight flanks and each having a curvature troughs and crests, according to the preamble of claim 1.
  • a heat exchanger is for example US 3,673,846 known.
  • a heat exchanger network and a heat exchanger equipped therewith is known, wherein the heat exchanger network has a plurality of flat tubes and arranged between the flat tubes, in heat-conducting contact with these lamellae and wherein the heat-conducting contact is made solely by mutual tension of the flat tubes and fins.
  • the lamellae are elastically deformable in the direction of the tension, whereby an assembly effort is to be reduced.
  • corrugated ribs are used between individual tubes of such heat exchangers in a known manner, which improves the heat transfer usually soldered to the pipes.
  • an adhesive bond for fixing the corrugated fins to the pipes is also known, with the adhesives used hitherto being equipped, for example, with heat conducting particles of boron nitride or aluminum in order to be able to improve the thermal conductivity of the adhesive.
  • the adhesives used hitherto being equipped, for example, with heat conducting particles of boron nitride or aluminum in order to be able to improve the thermal conductivity of the adhesive.
  • such sauceleitp adversely affect the price of the adhesive and its processing.
  • gluing a soldered network but this two production processes must be combined, which also has a negative effect on the cost.
  • soldering constructions known from the prior art are designed to compensate for manufacturing tolerances arising during assembly via the tube geometry.
  • this is not possible with a purely glued heat exchanger and, for example, with an extruded tube geometry.
  • corrugated fins are used, which can take such a compensation function.
  • the present invention addresses the problem of providing a heat exchanger of the generic type an improved or at least one alternative embodiment, which overcomes in particular the disadvantages known from the prior art.
  • the present invention is based on the general idea to be able to create a heat exchanger on the one hand, which can be glued, and On the other hand, however, these equip comparatively inexpensive and with appropriate tolerance compensation options and a high heat exchanger performance.
  • the heat exchanger according to the invention has in a known manner tubes and interposed corrugated fins with straight flanks and each having a curvature having wave troughs and wave crests.
  • the curvature of a wave crest can alternatively be designed in two embodiments according to the invention. In the two alternatives, the wave crests are optimized in that a minimum investment is enforced by a spring action, whereby an improved heat transfer capability and thus a minimum system performance can be guaranteed.
  • the shape of the wave crest of such a corrugated fin according to the invention is in bionic form based on the shape of a human foot. It is particularly advantageous that results in a pressure-stable rib or flank of the corrugated fin, which avoids buckling under pressurization.
  • the first alternative embodiment of a curvature of a wave crest has a curved first section and a linear second section, the second section being twice as long as the first section and the two sections having an opposing gradient between 0.1 and 0.5%. respectively.
  • the domed first section has a positive slope of +0.1 to + 0.5% while the linear second section has a negative slope of -0.1 to -0.5%.
  • the slope of the curved first section is determined between its beginning and end point.
  • the wave crests of the corrugated fin By such a curvature of the wave crests of the corrugated fin, on the one hand, a required tolerance compensation can be achieved and, on the other hand, a two-dimensional contact of the corrugated fin on the tubes, whereby a high heat transfer and thus high performance of the heat exchanger can be achieved.
  • the troughs are of course formed according to the wave crests, only in reverse, ie, for example, by an upside-down first and second section. The wave crest can thus correspond to a mirrored wave valley or vice versa.
  • the first section again passes over a high point in the second section and wherein at unloaded corrugated fins between two adjacent wave crests a tolerance distance a remains, which is dimensioned so that it is pressed when installed in the heat exchanger state to zero and thereby abut the wave crests on block together.
  • the two sections are arranged in mirror image to each other, as long as the mirror axis passes through the high point.
  • the horizontal tolerance distance a between two wave crests or between two wave troughs can thus preset determine a possible vertical spring travel, as contact after exhausting this spring travel two adjacent wave peaks or troughs and thus creates a very stable arch structure.
  • buckling of the individual flanks or corrugated ribs is prevented and, on the other hand, a sufficient pressure-stable surface is created in order to displace superfluous adhesive from the gap between the wave crest or the wave trough and the tube. This is especially important for optimum heat transfer.
  • the remaining adhesive layer is thereby reduced to a minimum while ensuring freedom from bubbles.
  • an opposing gradient of the first and second sections is about 0.3-0.4%. This makes it possible to create a comparatively shallow wave crest or a comparatively shallow wave trough, which on the one hand enables a flat and thus good heat transfer connection to the pipe and on the other hand enables the desired tolerance compensation.
  • an adhesive layer in particular by laminating, is applied on an outer side of the tubes.
  • the adhesive layer can thus be applied, in particular in the form of an adhesive film or an adhesive film, whereby the application of the adhesive layer is possible not only economically but also of extremely high quality.
  • the corrugated fins are made of a good thermally conductive material, preferably aluminum, copper, etc. This can also be thought of a combination of materials, since the adhesive layer acts insulating and thus contact corrosion is prevented.
  • the heat exchanger is expediently designed as an evaporator, as a radiator, as a condenser, as a charge air cooler, as a chiller, as an oil cooler, as a radiator or as a PTC heater.
  • a heat exchanger 1 which may be formed, for example, as an evaporator, as a radiator, as a condenser, as intercooler, as a chiller, as oil cooler, as a radiator or PTC heater, tubes 2 and interposed corrugated fins 3 with straight edges 4 and each one vault 5 having wave troughs 6 and wave crests 7 (see also the Fig. 2 and 4 ) on.
  • the corrugated fins 3 are glued to the tubes 2 via an adhesive layer 8.
  • the bulge 5 of a wave crest 6 according to the invention according to two alternative embodiments formed:
  • this has a curved first section 9 and a linear second section 10, wherein the linear second section 10 is twice as long as the first section 9.
  • the length used for this refers to an extension along a central axis 12.
  • the curved first section 9 has a slope of 0.1-0.5%, preferably between +0.3 and +0.4%, while the linear second section 10 has a gradient of -0 , 1 to -0.5%, preferably from -0.3 to -0.4%.
  • the height of the curvature 5 to the transition into the respective flanks 4 is in accordance with the Fig. 2 and 4 denoted by m.
  • the curvature 5 of a wave crest 6 (cf. Fig. 4 ) have a curved first portion 9 and a curved in the same direction second portion 10, which have the same length L (along the central axis 12) and are therefore formed the same length.
  • a tolerance distance a which is dimensioned such that it goes to zero when installed in the heat exchanger 1 state and thereby the wave crests 6 rest on block to each other.
  • the difference between the wave crests 6 and the wave troughs 7 can only be seen in a reflection with respect to the central axis 12, so that the wave crests 6 correspond to the wave troughs 7.
  • the adhesive layer 8 is applied to the outside of the tubes 2, for example by laminating, whereby such an adhesive layer 8, for example in the form of an adhesive film or an adhesive film, not only cost, but also with low layer thickness and can be reliably applied.
  • an adhesive layer 8 for example in the form of an adhesive film or an adhesive film, not only cost, but also with low layer thickness and can be reliably applied.
  • the individual corrugated fins 3 are glued to the respective adjacent tubes 2, wherein the corrugated fins 3 preferably lie flat against the tubes 2 in the region of their wave crests 6 and their wave troughs 7, thereby enabling a good heat transfer.
  • the corrugated fins 3 according to the invention are preferably formed of aluminum and thus a good heat-conducting material. In theory, a combination of different materials is grateful by gluing the corrugated fins 3 with the tubes 2, so that the corrugated fins 3 can be formed from a different material to the tubes 2, without the risk of contact corrosion exists.
  • corrugated fins 3 formed according to the invention manufacturing tolerances arising during assembly of the system 3 and pipe 2 can be compensated for particularly easily, as a result of which air inclusions and higher adhesive layer thicknesses, which have an insulating effect and thereby cause a reduced performance of the glued heat exchanger 1, can be avoided.
  • the bionic embodiment of the bulges 5 an enlargement of the contact surface on the tube 2 can be achieved, whereby a likewise improved heat transfer can be achieved.
  • the according to the Fig. 2 illustrated embodiment of the corrugated fins 3 may of course be symmetrical and not asymmetric as in the example shown.
