Definitions
- the invention relates to a heat exchanger, in particular a Gas cooler for CO2 - air conditioning systems for motor vehicles according to the generic term of claim 1.
- a heat exchanger was by the DE-A 196 49 129 known to the applicant.
- Such constructions in particular for CO2 air conditioning systems are characterized by two Headers and an intermediate heat exchanger network characterized, which consists of flat tubes, in particular Multi-chamber pipes and interposed corrugated fins exists.
- the Flat tubes are twisted end and are of appropriate Pulled through or slits in the headers fluid-tight. Inside the headers and the multi-chamber flat tubes flows Refrigerant, and on the outside of the flat tubes, d. H. through the Corrugated ribs flow ambient air to dissipate the heat of the refrigerant.
- Such heat exchangers are either parallel or Motig flows through, in the latter case partitions in the headers to Deflection of the refrigerant are provided.
- the heat exchanger in addition to the two headers a distribution device, via which the entering refrigerant flow to two outer inlet chambers is distributed and from there meandering to the middle area of the Heat exchanger flows to finally come out of a middle chamber withdraw.
- the refrigerant preferably CO2
- z. B. is applicable for capacitors - is especially in the horizontal position of the refrigerant pipes, d. H.
- the vertical position of the headers ensures that the exiting Refrigerant flow is not in the range of warm recirculation flow device. Rather, the exiting refrigerant flow is in one Flow region of the cooling air, which is relatively undisturbed and thus a ensures effective cooling of the refrigerant flow.
- the distribution device is a tube formed, which is arranged parallel to one of the manifolds.
- Both tubes can be two-piece or be formed integrally as an extruded part. This gives a compact design for this heat exchanger without additional Connections, but only with a refrigerant inlet and a Refrigerant outlet for the entire heat exchanger.
- the thermal Insulation between the two tubes serves to prevent heat from entering refrigerant to the escaping refrigerant - almost on the Ways of internal heat exchange - is transmitted.
- the manifold in particular in one-piece extruded construction in a known manner with a longitudinal slot for receiving the twisted ends of the flat tubes be provided, d. H. approximately in the manner according to EP-A 0 992 757 of Applicant.
- FIG. 1 shows a gas cooler 1 for an air conditioning system for a motor vehicle operated with CO2 as a refrigerant.
- a gas cooler is preferably installed in the front region of the engine compartment, where the coolant cooler for the internal combustion engine is located. In this respect, in this area, in particular in stop-and-go operation, recirculation flows of warm air from the engine area can be expected.
- the gas cooler 1 is shown here only schematically and has on its left side a manifold 2 and on its right side a manifold 3, which is assigned a distributor 4. Between the headers 2 and 3, which are arranged vertically in the vehicle, are parallel, here shown only by arrows 5 flat tubes, between which corrugated fins, not shown, which are acted upon by the ambient air, are.
- the distributor 4 is tubular in cross-section and arranged parallel to the manifold 3; it has a refrigerant inlet 6 and two overflow openings 7 and 8, which open from the interior 9 of the distributor 4 into an upper chamber 10 and a lower chamber 11.
- the manifold 3 is divided into a total of four chambers, namely 10 and 11 and 12 and 13, through the partitions 14, 15 and 16.
- the opposite manifold 2 is divided by partitions 17 and 18 into two outer chambers 19 and 20 and a middle Subdivided chamber 21, which has a refrigerant outlet 22.
- the refrigerant passage through this gas cooler 1 is as follows:
- the refrigerant enters via the inlet 6 in the distributor 4, where it distributed in the interior 9 and in each case via the overflow 7 in the overhead chamber 10 and over the overflow 8 in the bottom lying chamber 11 passes.
- the refrigerant flow is thus in two equal Divided mass flows, each following the arrows 5, from right to flow through the gas cooler on the left and the chambers on the other side Reach 19 and 20.
- both refrigerant flows back into the deflected other direction to enter the chambers 12 and 13, where they are redirected again, after renewed flow through the Combine gas cooler 1 in the end chamber 21 and through the Refrigerant outlet 22 leave the gas cooler 1.
- Fig. 2 shows the manifold 3 and the distributor 4 of FIG. 1, here as a unit 30, which consists of a manifold 31 and a manifold 32.
- the manifold 31 is divided by partitions 34, 35, 36 into individual chambers, in particular an upper chamber 37 and a lower chamber 38. The latter are via flow channels 39 and 40 with the manifold 32 in flow communication.
- an air gap 41 (which may also be filled with an insulating material) 41 is arranged between the walls of the manifold 31 and the manifold 32.
- This air gap 41 can be subsequently milled into the extruded part, as also apparent from Fig. 2b.
- the flow flow of the refrigerant takes place in such a way that the refrigerant flow G enters the end face at an inlet opening 42 in the manifold 32 and is distributed there; Via the overflow channels 39 and 40, which preferably have the same cross-section, the refrigerant flow G is divided into two equal streams G1 and G2, which enter into the chambers 37 and 38. From there, the refrigerant flow takes place in the manner described for Fig. 1.
- Fig. 2a is a cross section through the extruded unit 30 along the line A - A shown in Fig. 2, with in the longitudinal slot 33 (Fig. 2) tight soldered, twisted flat tube ends 43.
- the longitudinal slot 33 Fig 2
- the overflow channel 39 can be drilled from the outside after the extrusion process.
- FIG. 2b shows a further cross-section, in accordance with the line B - B in Fig. 2: here, the air gap 41 is clearly visible, it can also be made by machining after the extrusion process.
- the manifold 32 and the manifold 31 are thermally conductive connected only in the region of the overflow 39 and 40, while they are completely isolated in the central region, which has a performance-enhancing effect on the cooling of the refrigerant, because thus the back-flowing refrigerant in the middle chambers 44 and 45 is not reheated by the warmer entering refrigerant in the manifold 32 again.
- FIG. 3 shows a further embodiment variant of the extruded unit with a collecting tube 50, which has a larger diameter than the associated distributor tube 51.
- One of the two transfer channels is designated 52.
- the collecting tube 50 like the exemplary embodiment described with reference to FIG. 2, is likewise provided with a longitudinal slot for receiving twisted flat tube ends 53.
- Fig. 4 shows a further embodiment of a manifold / manifold unit, wherein a manifold 60 and a manifold 61 are designed as a separately prepared tubes, which are connected via an intermediate piece 62 (the second is not shown here), preferably soldered.
- a manifold 60 an opening 63 and the manifold 61 an opening 64 and the intermediate piece 62 has an opening 65.
- the openings 63, 64 and 65 are aligned and thus form one of the two transfer channels.
- a slot 66 twisted flat tube ends 67 are used and soldered, wherein - as described above - are arranged on the outside of the flat tubes corrugated ribs 68.
