Definitions

  • the invention relates to a heat exchanger, for example, condenser or gas cooler for the air conditioning of a motor vehicle having at least two fin-tube blocks having on both opposite sides of the fin-tube blocks at least two manifolds which are in fluid communication with each other, the Collecting tubes have closing or separating plates and connection or connection blocks,
  • This heat exchanger is known from European patent application no. EP 414 433 A2 known.
  • the two manifolds are in fluid communication with each other by means of two connecting blocks.
  • the two connection blocks are attached as individual parts to a manifold and soldered there.
  • both connection blocks are screwed together.
  • This heat exchanger, assembled after soldering, is not as stable against high pressures as it does with CO2 as a refrigerant.
  • Fig. 1 is a view of a portion of the heat exchanger according to the invention, in particular a gas cooler for using CO2 as a refrigerant, is shown.
  • the condenser gas cooler
  • the special type of condenser are two identical heat exchangers, one behind the other placed and connected together, in such a way that the one collector 2A and 3A are directly behind each other and are connected and also the other collectors 2B and 3B in the flow direction of the cooling air directly behind each other.
  • This structure of the condenser has the advantage that the entire surfaces of the fin-tube blocks 1 are available for heat exchange.
  • the left-hand collectors 2A and 3A in FIG. 1 and the right-hand collectors 2B and 3B are each connected to a connecting block 10 which cooperates with a closing or separating plate 4 .
  • the terminal block 20 which is formed, for example, as shown in Figure 7, the refrigerant is passed into the rear header 2A . It is distributed over the flat tubes 5 and flows into the collector 2B on the opposite side of the heat exchanger.
  • the connection block 10 directs the refrigerant from the collector 2B in the collector 3B located further to the front .
  • closure or separating plate 4 can be used for such purposes, both in cooperation with a connection or terminal block 10 as well as alone, that is, without the block 10. Also, a plurality of connection blocks 10 at the collectors 2 and 3 at any that is, be arranged by the skilled person to be provided bodies. Accordingly, the pictorial representations with closing or separating plates 4 lying at the ends of the collecting tubes 2, 3 and with connecting block or connecting block 10 should not be understood as limiting this. Furthermore, it should be pointed out that the closure or separating plate 4 could only be located on a single collector 2 or 3 , although the embodiments shown only show closure or separating plates 4 which extend over two adjacent collectors 2 and 3 .
  • FIG. 2 shows a detail of FIG. 1 enlarged. It is shown a corner of the capacitor.
  • the two collectors 2A and 3A are connected to the connection block 10 .
  • the closure plate 4 fixes the connecting block 10 at the desired locations, in this case in the region of the ends of the collector 2 and 3. It can be seen a flat tube 5 , an indicated rib 6 and a side plate 11 extending over the capacitor in its entirety Depth extends.
  • FIG. 3 shows a section in FIG. 2, which passes through the closure plate 4 .
  • the closure plate 4 has an approximately B-shaped form.
  • the two parts 4d and 4e are nearly circular. In the middle, they are connected to each other by a web 4c , from which a protrusion 4f protrudes, which engages in a gap 14 .
  • This intermediate space 14 is formed from wall parts 202 of one collector 2, wall parts 302 of the other collector 3, and from the remainder 15r of the slot 15 in the connecting block 10.
  • these parts 4c, 4d, 4e, and 4f and 202, 302, 15r may be shaped to achieve the desired goal of pre-fixing the connection block 10 by the closure plate 4 .
  • Fig. 4 shows the end of the collector 2 and 3 in plan view.
  • the connection block 10 and the closure plate 4 are slightly over.
  • the closure plate 4 may also be formed so that it has two cup-shaped bulges, which are inserted into the ends of the collector 2 and 3 .
  • Fig. 5 shows a section other than Fig. 3 through the connecting block 10, namely a vertical section.
  • the connecting block 10 has a flow-through opening 12 , through which the refrigerant from the collector 2 to the collector 3 can flow.
  • the slots 15 and 205 can be seen here. This is also clearly visible in FIG.
  • the refrigerant is indicated by the dashed arrow 60 .
  • the refrigerant flows from the small fluid channels 51 in the flat tubes 5 in the collector chamber 22 of the collector 2. From there it flows through the opening 23 of the header 2 in the flow opening 12 of the connecting block 10. Through the opening 33 of the header 3, the refrigerant enters the collecting space 32 of the collector 3, to then flow back into the small fluid channels 51 of the flat tubes 5 .
  • FIG. 7 shows an alternative embodiment in which a connection block 20 according to the invention is used. It has an inflow or outflow opening 25 through which the refrigerant enters or leaves the condenser can.
  • This connection block 20 is also prefixed by the closure plate 4 in order then to obtain a fluid-tight connection during soldering. As a result of this prefixing, the connection block 20 can no longer slip vertically. He also can not fall, because he also in a soldering frame (not shown) is clamped.
  • the terminal block 20 can be attached anywhere, but then the collector 2 or 3 must be closed at the top or bottom by individual closure plates 4 .
  • connection block 10 shows a connection block 10 which is at the same time a connection block 20 .
  • the refrigerant again illustrated by a dashed arrow 60 , is supplied via feed lines 42 not shown in detail through the inlet opening 41 of the flow opening 12 . It is distributed, as shown, through the two openings 23 and 33 of the respective collector 2 and 3 to the collecting chambers 22 and 32 and then flows into the small fluid channels 51 of the flat tubes . 5
  • connection block 10 with closure plate 4 proposed here can also be used in the case of more than two heat exchangers arranged one behind the other, which are to be connected to one another and fastened to one another.
  • connection block 10 of the type can be designed so that it connects with the flow opening 12, only two of the three heat exchangers. In extreme cases, even the flow-through opening 12 can be dispensed with in order to achieve only optimal fastening.
  • FIGS. 9-11 show a development which, in addition to the advantages already mentioned, also offers the possibility of making the flow of the refrigerant more favorable and / or of adapting it to specific conditions of a gas cooler in a cooling module of a motor vehicle.
  • an oblique through hole 12 was provided in the connection or connection block 10, which is provided here as a pure connection block 10 but could of course be designed as a connection block (or both), the ends of which are provided with corresponding holes 23, 33 in the Hoppers 2, 3 correspond.
  • the refrigerant for example, from an overhead portion of the one header pipe 2 in a lower portion of the other header pipe 3, or vice versa out become. It is also to be expected here with lower pressure loss, since the refrigerant is not deflected so abruptly.
