Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1, a method for producing a heat exchanger and an arrangement from a first heat exchanger to a second.
  • a heat exchanger consists of a tube bundle of rectangular or flat oval tubes, ribs being arranged between the tubes. At the opposite tube ends, the tubes are enclosed in a tube sheet or tube frame. This tube sheet has a protruding U-shaped collar in the longitudinal direction on the edge in each case for receiving the hood-shaped collecting container. After the tube ends have been connected to the tube sheet, the collecting container with its legs is placed on the U-shaped collar of the tube sheet and flanged with it.
  • a disadvantage of the known heat exchanger is that the heat exchanger requires an increased space requirement due to the protruding design of the tube sheet.
  • the present invention is therefore based on the problem of specifying a heat exchanger, as well as an arrangement of heat exchangers and a method for producing a heat exchanger, so that heat exchangers can be produced in a simple and cost-effective manner with a small space requirement.
  • the invention has the features of claim 1, claim 13 and claim 17.
  • the tubes are expanded at the tube ends in such a way that on the one hand long connecting surfaces are formed for connecting the tube ends to adjacent tube ends and, on the other hand, short connecting surfaces are formed for connecting to a collecting container placed in the end regions of the tubes.
  • the pipe end is widened perpendicular to the long side of the pipe, with a narrowing perpendicular to the narrow side of the pipe. The widening of the tube perpendicular to the long side of the tube enables the long connecting surfaces of one tube end to be in direct contact with a connecting surface of an adjacent tube end. The provision of a tube sheet can therefore be omitted.
  • the collecting container can be connected to the pipe block directly on the outside connecting surfaces, in particular on the short connecting surfaces, which extend perpendicular to the narrow side in the transverse direction of the pipe while reducing the spatial extent of the pipe. This results in a significant reduction in the depth of the heat exchanger's space requirement.
  • a tube frame can be omitted due to the direct abutment of the collecting container on the short connecting surfaces, so that material is saved.
  • the narrowing on the narrow sides of the tube is dimensioned such that it is greater than or equal to the leg thickness of the collecting container. It is thereby achieved that the total heat depth of the heat exchanger is not greater than the pipe block depth.
  • the tubes, the fins and the collecting container consist of a pure metal material, so that the heat exchanger can be easily recycled.
  • the tubes, the fins and the collecting container are advantageously made of an aluminum alloy in order to achieve the greatest possible weight reduction.
  • the method according to the invention for producing the heat exchanger has the particular advantage that the number of production steps can be reduced. After the pipe ends have been widened, the pipe package consisting of pipes and fins is placed in a soldering furnace together with the attached collecting container, in which the parts to be connected are simultaneously soldered in one work step.
  • Fig. 1 shows a front view of a heat exchanger 10 with parallel tubes 11, which extend from a header 12 to an opposite header 13, which can be used in automotive engineering for engine cooling.
  • Side parts 8 limit the heat exchanger 10 in the vertical direction and are connected at the ends to the collecting tanks 12 and 13, respectively.
  • the collecting container 12 has a feed nozzle 6 in an end region for supplying a medium to be cooled in the collecting container 12.
  • the medium to be cooled is distributed in the collecting container 12 and is conducted via the pipes 11 to the second collecting container 13, from which it is led out of the collecting container 13 via a discharge nozzle 7.
  • the tubes 11 are designed as flat oval tubes or tubes with a rectangular cross section with opposite longitudinal sides 14 and narrow sides 15 arranged laterally. In one end region, the tube ends 16 are expanded perpendicular to the longitudinal side 14.
  • the long sides 14 of the tube 11 extend over conical long transition surfaces 17 to long connecting surfaces 18 of the tube end 16.
  • the narrow sides 15 of the tube 11 narrow in the direction of the tube end 16 via a short transition surface 19 which is conical in the direction of a central axis 20 of the Tube 11 extends to a short connecting surface 22.
  • the tubes 11 are arranged in a row, with air-conducting corrugated fins 21 being arranged between the tubes 11.
  • the tube end 16 is rectangular in cross section, in the form of the parallel, opposite long connecting surface 18 and the opposite, short connecting surface 22 arranged at right angles thereto. The widening takes place in such a way that the circumferential length of the tube end 16 along the long and short connecting surfaces 18 and 22 is equal to the circumferential surface of the tube 11 in the region of the long and narrow sides 14 and 15, so that the thickness of the long and short connecting surfaces 18 and 22 is equal to the thickness of the long and narrow sides 14 and 15 is.
  • the surface of the tube 11 at the tube ends 16 is not enlarged.
  • the long connecting surfaces 18 abut the long connecting surfaces 18 of adjacent pipe ends 16 and are connected to them by soldering.
  • the inclination of the conical long transition surfaces 17 is determined by the width of the corrugated ribs 21.
  • a U-shaped collecting container 23 with a flat leg 24 and a curved leg 25 is placed on the tube ends 16.
  • the leg ends 26 and 27 abut the short connecting surfaces 22 and are soldered to them.
  • the leg ends 26, 27 are positively fitted into grooves in the side part 8 provided for this purpose and are connected to them at the same time by soldering.
  • the short connecting surfaces 22 are arranged in comparison to the narrow sides 15 in the direction of the central axis 20, the distance reduction from the central axis 20 being at least equal to or greater than the thickness of the leg ends 26, 27, the collecting container 23 is in the lateral direction of the tubes 11 not over.
  • the lateral extent of the collecting container 23 is thus equal to or less than the transverse extent of the tubes 11. This ensures a considerable reduction in the space requirement of the heat exchanger 10, the space requirement only being determined by the depth of the tube 11 (distance of the narrow sides 15 from the opposite narrow side 15). is set.
  • the supply nozzle 6 for supplying a medium to be cooled is attached to the flat leg 24 of the collecting container 23.
  • the collecting container 23 is advantageously produced by extruding a block into a U-shaped profile.
  • the collecting container 23 can also be formed by rolling and subsequent bending, in particular by deep drawing. Care must be taken to ensure that by fitting a suitable tool in the lateral direction, namely on the short connecting surfaces 22, the same are arranged perpendicular to the long connecting surfaces 17, so that the edge between the short connecting surface 22 and long connecting surface 17 has a small radius. This prevents the formation of a gap or gap, so that the leg ends 26, 27 of the collecting container 23 are connected to the short connecting surfaces 22 of the tube block by sealing soldering.
  • the collecting container can be designed as a cylindrical collecting container 29 according to a second exemplary embodiment according to FIGS. 5 and 7 .
  • This collecting container 29 is preferably produced by deep drawing.
  • Parallel collars 30 and 31 form a recess in the collecting container 29, into which the tube packet is inserted by abutting the short connecting surfaces 22 on the inner sides of the collars 30 and 31.
  • the end faces of the collecting container 29 are sealingly connected to a lateral surface 32 of the collecting container 29.
  • the collecting container 29 can have an axial recess in the area of an end face for the contact of a connection piece (not shown).
  • the end face of the collecting container 29 includes the side part 9 which is in contact with the outer long connecting surface 18 and is included connected by soldering.
  • the tube assembly composed of the corrugated fins 21 and the tubes 11 and the collecting containers 12, 13, 23, 29 consist of a pure metal material.
  • the recyclability of the heat exchanger 10 is thereby facilitated.
  • An aluminum alloy is used as the preferred material for these components, which enables the weight of the heat exchanger 10 to be reduced, in particular when used in motor vehicle construction.
  • the use of other recyclable materials is possible. It can too Materials made of copper or steel for the pipes and plastic for the collecting container are used, the pipes or the tube package being glued to the collecting container.
  • the method for producing the heat exchanger 10 is shown below. After the receptacles 12, 13, 23 and 29 of different shapes intended for connection to the pipes 11 have been shaped to fit precisely by deep drawing or extrusion, the pipe block with the widened pipe ends 16 is inserted into the recesses provided in the receptacles 23 and 29. Thereafter, the pipe ends 16 are connected to each other at the long connecting surfaces 18 and the pipe ends 16 are connected to the collecting container 23 or 29 at the short connecting surfaces 19.
  • This connection is preferably made by soldering, at least the connection points in question having been previously sprayed with a flux. This flux is preferably non-corrosive. However, other soldering methods which are included in this invention are also suitable for connecting the relevant parts.
  • the heat exchanger 10 can advantageously be connected to a second, immediately adjacent heat exchanger 28.
  • This heat exchanger 28 can be, for example, a condenser of an air conditioning system or a charge air cooler.
  • the heat exchanger 10 can either be designed with a U-shaped collecting container 23 or a cylindrical collecting container 29.
  • the first heat exchanger 10 is connected to the second heat exchanger 28 via a connecting element 5.
  • the connecting element 5 is U-shaped, wherein a first leg 33 fits into a groove 34 of the heat exchanger 10 and a second leg 35 of the connecting element 5 fits into a groove 36 of the heat exchanger 28.
  • the legs 33 and 35 are connected to the heat exchanger 10 or 28 by soldering, which can be carried out simultaneously with the soldering of the tube package within the heat exchanger 10.
  • the collecting tank 23 of the heat exchanger 10 is connected in one piece to a collecting tank 37 of the heat exchanger 31 via a web 38. As a result, the mechanical stability of the arrangement consisting of the heat exchanger 10 and the heat exchanger 31 is increased.
  • the heat exchanger 10 is connected in one piece to a U-shaped connecting element 39, the leg 40 of which comprises a protruding nose 41 of an adjacent heat exchanger 42.
  • the heat exchanger 42 has a further curved nose 43, which rests on an extension 44 of the collecting container 23.
  • the lugs 41 and 43 of the heat exchanger 42 are connected to the leg 40 and the extension 44 of the heat exchanger 10 by soldering, this soldering process taking place simultaneously with the soldering process to form the heat exchanger 10.
  • the extension piece 44 has a recess 45, which serves to locate a possible leak point more easily after connecting the heat exchanger set formed from the heat exchanger 10 and the heat exchanger 42 during a leak test.
  • the heat exchangers 28 and 42 preferably consist of an aluminum alloy, at least the points to be connected being provided with a non-corrisive flux.
  • the combination of a first heat exchanger 10 with a heat exchanger 28 or 42 can thus be produced in a simple manner in a single work step.
  • a U-shaped collecting container 47 is connected to the tube packet in each case in the lateral area via a likewise U-shaped extension piece 48.
