Definitions

  • the invention relates to a heat exchanger of the type specified in the preamble of claim 1.
  • a heat exchanger with an upper and a lower water tank in which the pipe ends of a heat exchanger block formed from pipes and fins open.
  • the upper water tank has an inlet on one side and the lower water tank has an outlet for the heat exchanger fluid.
  • the individual tubes of the heat exchanger are acted upon to different degrees, i.e.
  • the amount of heat exchanger fluid that flows through the individual heat exchanger tubes is very different, the difference being essentially influenced by the position of the inlet or the outlet and the installation position of the heat exchanger itself.
  • An uneven loading of the parallel heat exchanger tubes or parallel pipe strands is particularly noticeable in heat exchangers operated with a refrigerant, such as evaporators of air conditioning systems, which leads to a considerable reduction in the performance of the heat exchanger.
  • GB-OS 2 0 78 362 has already described a heat exchanger in which a separate inlet pipe is provided for each of the parallel-connected pipe coils that begin and end in a connection box. This measure ensures that the coils are evenly charged with fluid; however, such a solution is unsuitable in terms of manufacturing costs for large series production, since several pipes with different shapes and a large number of pipe connections are necessary.
  • the distribution device consists of a simply designed and inexpensive to manufacture body.
  • the distribution device can consist of an injection-molded plastic body or a metallic, commercially available semi-finished product, which is given the desired pitch of the coil by torsion about the longitudinal axis. This results in a distribution device in which there is no extreme change in direction of the fluid and therefore no appreciable pressure losses.
  • a coiled one can be used in a second connection box
  • Profile body of the same shape can be provided as a collecting device.
  • a preferred development of the subject matter of the invention is that a distribution and collecting device formed from a common profile body is arranged in the connection box and that an equal number of distribution channels and collecting channels is present between the partition walls.
  • an arrangement serving at the same time as a distribution and collection device is created only by a larger number of ribs of the profile body forming partitions.
  • This arrangement is particularly suitable for heat exchangers constructed from tubular forks.
  • an end plate is arranged on each end face, the collection channels on the input side and the distribution channels on the output side being closed.
  • the distribution device according to the invention can additionally be provided with a flow distributor, as is used for example for evaporators of air conditioning systems, without any changes.
  • the openings in the connection box are of different sizes.
  • the opening closest to the inlet has the smallest cross section and the opening furthest away has the largest cross section.
  • connection box is made of plastic, connection pieces for connecting the heat exchanger tubes can be provided in a simple manner.
  • the distributor device In order to reduce the flow resistance that the cross-sectional area of the distributor device forms, it is proposed to design the distributor device conically on the side facing the inlet. It is expedient for the connection box to have a conical taper which merges into the inlet, the opening angle of the cone corresponding to the angle of the cone, and the part of the conical surface adjacent to the base of the cone is covered by the conical taper.
  • the cone of the connection box results in a fixation of the distribution device on the one hand and an enlargement of the passage cross-section relative to the inlet on the other hand.
  • a baffle plate with a swirl chamber in front of it in order to achieve the most homogeneous possible wet steam mixture, it is expedient for a baffle plate with a swirl chamber in front of it to be arranged on the side of the distribution device adjacent to the inlet.
  • the baffle plate has an edge directed into the swirl chamber.
  • a nozzle is provided in the inlet in front of the swirl chamber, by means of which a part of the flow is prevented from being guided past the impingement plate without swirling.
  • the nozzle and the baffle plate are preferably made of a cavitation-resistant material.
  • the inlet cannot extend in the same direction as the connection box and for fluidic reasons the distribution device should not start in or immediately behind an arc, it is readily possible for the distribution device to be uniform in the connection box and the curve in the Inlet extends into it.
  • the pressure drop in the distribution system can be influenced by the ratio of the opening and pipe cross sections, which is particularly important in the case of refrigerant evaporators. For this reason, the openings can be designed as a throttle.
  • connection box is pressed onto the partitions of the distribution or collecting device by radially inward deformation.
  • a heat exchanger 1 serving as a radiator for a motor vehicle which essentially comprises a heat exchanger block 2 consisting of tubes 3 and ribs 4 running transversely thereto, as well as an upper connection box 5 and a lower connection box 6.
  • the upper connection box 5 and the lower connection box 6 are tubular, thus have cavities 5 'and 6' with a circular cross-section, and are closed on one end by a plate 7 or plate 8.
  • the upper connection box 5 has five openings 9 which each open into one of the tubes 3.
  • the lower connection box 6 has five openings 1o, to which the lower ends of the tubes 3 are connected.
  • the tubes 3 are soldered to the junction boxes 5 and 6.
  • connection box 5 there is a distribution device 11, which consists of a profile body which is star-shaped in cross section and coiled.
  • the star profile corresponds to the number of pipes 3 connected to the connection box 5, i.e. in the present case it is in the form of a five-pointed star.
  • Both the junction boxes 5 and 6 and the distribution or collection devices 11 and 12 consist of a metallic material according to this embodiment.
  • Partition walls 13 and channels 14 located between them are formed by the distribution device 11 and each extend from the inlet 15 over the entire length of the distribution device 11.
  • one of the openings 9 is located in the area of one of the channels 14, so that the total amount of fluid flowing in the inlet 15 is evenly distributed over the channels 14 and thus also equally over the heat exchanger tubes 3.
  • the collecting device 12 which is identical in design to the distribution device 11.
  • the collecting device 12 thus has the same partition walls 13 and channels 14 located between them, an opening 10 in each case being in the region of one of the channels 14.
  • the partial streams flowing in the channels 14 combine in the outlet 16.
  • connection box 5 for an evaporator is shown in FIG. 2, the tubes of the evaporator being provided with the reference symbol 3 in the same way as in FIG.
  • the connection Box 5 is tubular, as in FIG. 1, and closed at the end remote from the inlet 15 with a plate 7.
  • a distribution device 11 which corresponds to that in FIG.
  • the flow distributor 17 arranged in front of the distribution device 11 ensures that even with inhomogeneous flow media in the inlet 15, the phases are evenly distributed over each of the channels 14.
  • FIG. 3 the section along the line III-III in Figure 2 is shown.
  • a distribution device 11 with a star-shaped cross section in the tubular connection box 5, with five dividing walls 13 which are evenly distributed over the circumference protrude up to the inner wall of the connection box 5 and lie there sealingly.
  • the channel 14 directed vertically downward in FIG. 3 is located above the opening 9 in the connection box 5, to which the heat exchanger tube 3 is fastened.
  • FIG. 4 shows an embodiment variant of the connection box 5 shown in FIG.
  • the connection box 5 has five openings 19-23 which are of different sizes, the opening 19 closest to the flow distributor 17 having the smallest cross-section and that to the flow distributor 17 most distant opening 23 has the largest cross section. This measure compensates for differences in the pressure drop in the individual channels 14 due to the different distance between the individual openings 19-23 and the flow distributor 17.
  • FIG. 5 shows a tubular connection box 24 made of plastic, which is provided on one side with a fluid inlet 27 and on the other side with a fluid outlet 28.
  • the cross section of the fluid inlet 27 is slightly smaller than the cross section of the cavity 24 'in the connection box 24, as a result of which a shoulder 25 is formed at the end of the inlet.
  • This profile body 29, like the junction box 24, is made of plastic.
  • the profile body has ten partition walls 34 arranged in a star shape, a channel 35 or 35 ′ being formed between each two partition walls 34.
  • the collecting and distributing device 29 On the side facing the inlet 27, the collecting and distributing device 29 has an end plate 30, which covers every second channel 35 ′ and enables the fluid to pass into the other channels 35 through corresponding openings 32.
  • the end plate 31 is provided with openings 33 so that the channels 35 ', which are covered by the end plate 3o, are connected to the outlet 28.
  • the distribution and collection device 29 is on the one hand the shoulder 25 and on the other hand fixed in position by a locking ring 26.
  • the flow path of the fluid is indicated by arrows 36.
  • 37 and 38 designate pipe connecting pieces which engage in the ends of heat exchanger tubes 3 (not shown in FIG. 5).
  • FIG. 6 shows the section along the line VI-VI in FIG. 5.
  • This section clearly shows that the collecting and distributing device 29 consists of a star-shaped profile body which has ten partition walls 34 and channels 35, 35 'located between them.
  • the connecting piece 37 is connected to one of the channels 35 and the connecting piece 38 to one of the channels 35 '.
  • the outer end of the partition walls 34 lies against the inner wall of the tubular connection box 24 and, if this should be necessary for certain applications, can also be sealed, for example by an adhesive.
  • FIG. 7 shows the section along the line VII-VII in FIG. 5. From this illustration it can be seen that every second channel of the star-shaped profile body of the distributing and collecting device is covered by the end plate 31 and the channels 35 'are opened by corresponding openings 33 this page are open.
  • Figure 8 shows the connection box 24 with molded pipe connection piece 37 and 38 from the outside. On the left side of the connection box 24 in the drawing, this has a shoulder 25 at the transition to the inlet 27. On the right-hand side of the connection box 24 in the drawing, there is the outlet 28. According to the number of in 5 and 6 illustrated channels of the collecting and distributing device, the connection box 24 has five pipe connecting pieces 37 connected to the distributing channels 35 and five pipe connecting pieces 38 connected to the collecting channels 35 '.
  • the tubes of the heat exchanger block can be attached to the tube connecting piece 37 and 38, for example by connecting means, as described in DE-OS 31 26 o3o.
  • FIG. 9 shows a part of a connection box 5 with a distribution device 11 arranged therein, the distribution device 11 having partitions 13 and channels 14 and openings 5 in the connection box 5 for connecting the heat exchanger tubes 3 to the channels 14.
  • the latter On the side of the terminal box 5 facing the inlet 15, the latter has a conical taper 41 which merges into the inlet 15.
  • the distribution device 11 On the side facing the inlet 15, the distribution device 11 has an integrally formed cone 42, the cone angle corresponding to the conical taper 41 and the cone 42 abutting against it. Due to the conical design of the inlet end of the distributor 11, the flow resistance that the distributor 11 would have without the cone 42 is significantly reduced.
  • connection box 5 shows part of a connection box 5, the distribution device 11 and the openings 9, the tubes 3 and fins 4 corresponding to the embodiment according to FIG. 1.
  • connection box 5 there is an approximately bell-shaped transition on the side adjacent to the inlet 15 molded onto the inlet 15, which has a substantially smaller cross-section, and a baffle plate 45 is attached to the front side of the distributor 11 adjacent the inlet 15, which bells one onto the bell shaped transition 43 has directed edge 46 which is at a sufficient distance from the passage of the fluid to the inner peripheral surface of the terminal box 5.
  • a swirl chamber 44 is formed between the baffle plate 45 and the bell-shaped transition 43.
  • a nozzle 54 is provided in the inlet 15 adjacent to the g -shaped transition 43, which nozzle is formed by a corresponding deformation of the inlet pipe.
  • Such a measure is useful, for example, for evaporators, so that the most homogeneous possible wet steam mixture is generated in the swirl chamber before dividing the partial streams. The more homogeneous this mixture and the more even the distribution between the individual tubes, the better the efficiency of the evaporator.
  • Figure 11 shows a section along the line XI-XI in Figure 10 . It is clear from this view that there is still a sufficient distance between the edge 46 of the baffle plate 45 and the inner wall of the connection box 5 for the fluid to pass into the distribution channels 14.
  • connection box 47 arranged on a heat exchanger block 2 terminal box 47 having a bent in an arc of 0 ° 9 part 48, which merges into the feed 15th

  • a distribution device 5o which consists of a star-shaped profile body.
  • the distribution device 5o has corresponding to the number of openings 53 in the connection box 47, to which the tubes of the heat exchanger block 2 are attached are closed, the cross-sectional shape of a four-pointed star.
  • the spiral distribution device thus has four spiral partition walls 51 and channels 52 located between them.
  • the distribution is 5o before the turning of the part 48 of the junction box 47, thus introduced in the stretched condition, in the terminal box, and thereafter the bending is carried out of the part 48 with the therein distributor 5 0th
  • the deformation of the partition walls 51 takes place uniformly in the area of the bend, with compression naturally occurring on the inner radius and expansion on the outer radius, but there is no significant change in the cross sections of the channels 52.
  • connection boxes and the distribution or collection devices can be made of metal or plastic. It is also possible to combine parts of different materials, i.e. plastic with metal. Depending on the application, different requirements can be placed on the tightness of the individual channels. Thus, when using the subject matter of the invention in a radiator or radiator of a motor vehicle, a slight leakage is completely without any effects on the function of the distribution device. A very good seal can also be achieved by pressing a plastic distributor or collector into a metal connection box. Finally, in certain cases, an additional seal can be provided by an adhesive between the ends of the partition walls and the inner wall of the connection box. To fix the distribution or
