Definitions

  • the invention relates to a heat exchanger in a serpentine construction with the features from the preamble of claim 1.
  • This heat exchanger is known from DE 100 49 256 A1.
  • special deflection spaces are provided for the forwarding of the inner heat transfer medium (refrigerant) from a rear cooling line to the front cooling line (or vice versa), which are designed as individual tubes in which the ends of two cooling lines or sections constructed from serpentine bent multi-chamber flat tubes lead.
  • the cooling air flows through a plurality of cooling lines arranged one behind the other in the direction thereof.
  • Another heat exchanger is known from US 5,036,909, which is designed as an evaporator in an air conditioning system.
  • This heat exchanger also has a separate tube which is provided for deflecting the refrigerant from the inlet-side cooling line to two subsequent cooling lines and which is also intended to serve as a mixing chamber for uniformizing the temperature.
  • Another heat exchanger with a separate tube as a deflection space is known to the applicant from JP 06317363 A. The solution published there applies what has already been said about the solutions from the above documents.
  • the object of the invention is therefore to provide a improved heat exchanger, seen in the cooling air flow direction should have several strands but no separate deflection spaces are required.
  • the heat exchanger preferably has at least three cooling lines, which are reduced in the pipe cross-section, the cooling air first flowing through the cooling line, the cross-section of which is the smallest, then striking the medium-sized cooling line, and finally flowing through the largest cooling line, and that Refrigerant first flows through the largest cooling line, then through the middle and finally through the smallest. (Cross-counterflow) This provides a highly efficient capacitor for the air conditioning system, particularly in a motor vehicle.
  • Another exemplary embodiment has a cooling section with a larger cross section, into which the refrigerant first enters, and it has two following cooling sections with a reduced but equally large cross section. There may also be more than two following cooling lines, of which e.g. B. two have a reduced compared to the first cooling section but the same size cross section and further cooling strands compared to the two cooling strands of the same size are again reduced in cross section.
  • the inventive idea is also, as can be easily seen, applied with equal success to evaporators, although it was described above using the example of a condenser.
  • the component containing the distribution channel has a peripheral wall and a longitudinal partition wall, which extends approximately over the depth of two adjacent cooling lines and a transverse partition wall, the longitudinal partition wall and the transverse partition wall separating part of the cross section of the component, in which part the second deflection of the refrigerant is separated from one cooling line to the next cooling line, and furthermore it has an inlet channel (distribution channel) which extends along the longitudinal partition wall and the peripheral wall and leads to the inlet-side multi-channel flat tube end.
  • the component comprising the collecting duct has a peripheral wall and a transverse partition, the transverse partition hydraulically separating two adjacent cooling lines from the third cooling line.
  • the first deflection of the refrigerant takes place from one cooling line to the next cooling line.
  • the outlet-side multi-channel flat tube end of the third (smallest) cooling line ends in the remaining part of the component, namely in the collecting channel.
  • the cooling fins are preferably designed continuously across all cooling strands, what is cheap from the point of view of manufacturability.
  • the components are preferably generally tubular and take the entire cross section of a single multi-channel flat tube or several multi-channel flat tubes, which is / are soldered tightly and firmly. To there is a longitudinal slot in the component in a manner known per se, in which a End of the multi-channel flat tube (s) is / are inserted.
  • a refrigerant inlet is on an end face of the one containing the distribution channel Component arranged, which at the distal end of the multi-channel flat tube end End of the component is seated.
  • a refrigerant outlet is on an end face of the one containing the collecting duct Component arranged, which connects where the outlet side Multi-channel flat pipe end opens into the component.
  • the transverse partition in the component containing the distribution channel is arranged there, where the cooling line with the largest cross section to the adjacent cooling line adjoins, or where the multi-channel flat tube between the largest cooling line and the neighboring cooling line is hydraulically separated.
  • FIG. 7 A basic cross section through a single multi-channel flat tube 1 can be seen in FIG. 7.
  • This multi-channel flat tube 1 includes all (in the exemplary embodiment three) cooling lines 4 , 5 , 6 , which is illustrated by the corresponding reference numerals on the cross section.
  • the reference symbols 22 and 24 denote the partial transverse wall 22 in component 7 and the transverse wall 24 in component 9 , which can be seen in FIG. 6.
  • FIG. 6 A basic cross section through a single multi-channel flat tube 1 in FIG. 7.
  • This multi-channel flat tube 1 includes all (in the exemplary embodiment three) cooling lines 4 , 5 , 6 , which is illustrated by the corresponding reference numerals on the cross section.
  • the reference symbols 22 and 24 denote the partial transverse wall 22 in component 7 and the transverse wall 24 in component 9 , which can be seen in FIG. 6.
  • the reference numerals 22 and 24 were entered in order to clearly show that the transverse walls 22 and 24 provide the hydraulic separation between the cooling lines 4 , 5 , 6 there , because the Transverse walls 22 , 24 are arranged at the locations in the components 7 and 9 , respectively, which correspond to the locations marked in the multi-channel flat tube 1 with the reference numbers 22 and 24 , respectively.
  • the multi-channel flat tube 1 itself can be configured identically to channel walls 28 over all cooling lines 4 , 5 , 6 , as shown. It can also be clearly seen that the tube cross section of the cooling line 6 is larger than the same cross section of the cooling lines 5 and 4 .
  • the multi-channel flat tube 1 has only two channel walls 28 , which correspond to the positions of the partition walls 22 and 24 in the components 7 and 9, respectively.
  • Another exemplary embodiment, not shown, has more than two but significantly fewer channel walls 28 than shown in FIG. 7, the distances between the channel walls 28 and thus the cross sections of the individual channels not having to be of the same size.
  • the channel walls 28 give the multi-channel flat tube 1 greater stability against internal pressure.
  • the components 7 and 9 are generally tubular, preferably circular in cross section, with a circumferential wall 20 and 23 respectively . They extend approximately over the depth (Z direction, FIGS. 1 and 6) of all cooling strands 4, 5, 6.
  • the components 7 and 9 are equipped with a longitudinal slot 30 (FIG.
  • the arrangement of the partitions 21 , 22 , 24 is best seen in FIG. 6.
  • the partial transverse wall 22 in the component 7 has the effect that an inlet-side multi-channel flat tube end 11 is hydraulically separated from the remaining cross section of the multi-channel flat tube 1 , which means that within the component 7 there is no hydraulic connection to the remaining cross section of the multi-channel flat tube end 1 .
  • the remaining cross section of the multi-channel flat tube end 1 is assigned to the end of the cooling line 5 and the beginning of the cooling line 4.
  • the mentioned end and the mentioned beginning open in the second deflection space 13.2 , which is formed by the longitudinal partition 21 and the transverse partition 22 in the component 7 .
  • the distribution channel 8 is connected on one side via the passage 34 between the longitudinal wall 21 and the peripheral wall 20 to the inlet 25 and on the other side to the multi-channel flat tube end 11 on the inlet side.
  • Component 9 is configured somewhat more simply than component 7 because it only has the transverse partition 24 , which extends over the entire cross section of component 9 . Characterized 9, two separate compartments are formed in the component, the larger section, of which the first deflection chamber 13.1 is in which the said cooling line 6 associated end of the multiple channel flat tube 1 and the cooling line lead 5 associated with the beginning of the multiple channel flat tube. 1
  • the second department is the collecting space 10 , in which the outlet-side multi-channel flat tube end 12 assigned to the cooling strand 4 opens.
  • the heat exchanger consisting of three individual multi-channel flat tubes 1 which are approximately rectangular in cross section.
  • the multi-channel flat tube with the reference symbol 1.6 forms the cooling line 6 , with 1.5 the cooling line 5 and consequently with 1.4 the cooling line 4 .
  • the multi-channel flat tubes 1.6 , 1.5 and 1.4 have been bent in an identical manner in a serpentine manner, and they are each soldered to one another on their narrow sides 32 , which is only shown in principle. (Fig. 9)
  • the connected narrow sides 32 are located at the locations that correspond to the position of the partition walls 22 and 24, respectively.
