Definitions
- the invention relates to a heat exchanger, in particular a gas cooler for a CO2 refrigerant circuit of a motor vehicle air conditioning system, according to the preamble of claim 1.
- Heat exchanger for air conditioners with R134a as refrigerant eg. B. capacitors consist of a heat transfer network with flat tubes and both sides of the network arranged collecting pipes with circular or other cross-section.
- Other heat exchangers for air conditioning z. B. double-row evaporator after the DE-A 198 26 881 the applicant have a subdivided into two Lzanskammem collecting box, which is made of a prepared sheet metal blank by bending over the edge regions of the sheet metal blank. This gives a central, double-layered longitudinal partition, which is fixed by means of tongues in recesses of a flat header tank bottom.
- each longitudinal chamber communicates with a row of flat tubes.
- CO2 R744
- a manifold consists of four juxtaposed circular flow channels. The production of such an extruded manifold is expensive because of the tools required for it.
- the collection box is integrally formed and is bent from a sheet metal strip so that there are two longitudinal channels, however, - are different from this prior art - only with a flat tube row in fluid communication. Due to this design of the collecting tank, an approximately circular cross-section and thus a pressure-resistant collection box is made possible.
- the two-ply longitudinal partition is fixed and anchored by means of tongues in a central region of the metal strip, which facilitates the manufacture and increases the strength.
- the tongues for fixing the longitudinal dividing wall can be arranged either on the side facing the flat tubes or facing away. This increases the Krasmögtichkeiten the heat exchanger.
- notches are arranged in the longitudinal partition wall in the region of the flat tube ends, which project into the longitudinal channels, in which engage the flat tube ends.
- the flat tubes can be pushed into the collecting box relatively far - approximately to the middle - and formed with a maximum depth (the depth of the flat tube is measured in the direction of air flow).
- the collection box is thus only insignificantly lower than that Flat tube. This can be advantageously created space for transformations or passages.
- gaps are left between the notches and the flat tube ends, which may for example be U-shaped or arranged only laterally or above the flat tube. It is advantageous if the notches simultaneously serve as a stop for the flat tubes when they are pushed through the slot-shaped openings in the collection box. This results in a precise positioning of the flat tubes in the collecting box. Through the column to reach a pressure and flow compensation between the two adjacent longitudinal channels.
- the region of the collecting tank, in which the recesses are arranged with the tongues slightly inwards, d. H. be retracted in the direction of the longitudinal partition, resulting in a certain "sidecut" for the cross section of the header. This ensures that the cross sections of the longitudinal channels even more, d. H. beyond a circumference of 270 degrees to a circular cross-section, which benefits the strength and weight.
- Fig. 1 shows a section of a gas cooler 1 with a collecting box 2 and flat tubes 3, which open with their flat tube ends 3a in the collecting box 2 and are received in slot-shaped openings 4. Between the flat tubes 3 are - which is not shown - corrugated fins provided to increase the air side heat exchange surface.
- the gas cooler 1 is particularly suitable for use in a refrigerant circuit with CO2 as the refrigerant of a motor vehicle air conditioning system, but not limited to this application.
- the gas cooler is the primary side, ie flows through in the collecting tanks and the flat tubes of gaseous CO2 at a pressure of about 120 bar and the secondary side acted upon by ambient air; It has the task of cooling the CO2 gas from a temperature of approx. 150 degrees Celsius to 50 degrees Celsius. The resulting pressure is about ten times that of conventional condensers in a circuit with the refrigerant R134a.
- Fig. 2 shows the gas cooler 1 according to Fig. 1 in a section, wherein it is clear that the collecting box 2 is integrally formed. He has two Lzanskammem 5, 6, which are separated by a double longitudinal partition 7 from each other.
- the collection box 2 is made of a sheet metal plate or a sheet metal strip 8, which outer edge strips or longitudinal edges 9, 10, which are provided with tongues 11, 12. In the middle of the sheet metal tire 8, 12 recesses 13 are arranged according to the arrangement of the tongues 11 ,.
- the collecting box 2 is made from the prepared, ie cut and punched sheet metal strip 8 in such a way that the sides with the longitudinal edges 9, 10 bent to approximately cylindrical channels 5, 6 and that the longitudinal edges 9, 10 centrally and approximately perpendicular to a central Connection region 14 are returned, where they are inserted with the tongues 11, 12 in the recesses 13.
- the flat tubes 3 are inserted with their flat tube ends 3a in the openings 4 and protrude with its upper edge 3b about halfway in the free cross section of the longitudinal channels 5, 6 in. Since the cross section of the longitudinal channels 5, 6 here its has maximum width, resulting from the narrowing thereafter cross section, a stop for the flat tubes.
- Fig. 3 shows a section through the gas cooler 1 in the plane III-III in Fig. 2
- This section through the longitudinal channel 5 shows the partition 7, which has U-shaped notches 15 in the region of the flat tube ends 3a.
- a gap 16 is left, which releases a flow cross-section between the two longitudinal channels 5, 6.
- the refrigerant can also escape through this gap 16 in the middle of the flat tube ends 3a, and on the other hand, refrigerant can flow from one longitudinal channel 5 into the other longitudinal channel 6 and vice versa, so that pressure equalization can take place between the two longitudinal channels.
- the notches 15 and the gap form 16 are given by way of example only - the shape of the gap can also be modified in such a way that only above the flat tube ends, ie above the upper edge 3b, there is a gap or only laterally of the flat tube ends 3a. In the latter case, the Flachrohroberkante 3b would abut the notch in the partition wall 7, which would result in a stop.
- the tongues 11, 12 protrude beyond the outer wall of the collecting tank 2 and are each arranged approximately centrally between two flat tubes 3. However, it is also possible to skip one or more Flachrohrabments and to arrange the tongues 11, 12 and the recesses 13 at any intervals between two flat tubes.
- Fig. 4 shows a further embodiment of a gas cooler 20 with a collecting box 21 and flat tubes 22.
- tongues 23 and recesses 24 are here on the top of the collecting box 21, that is arranged on the flat tubes 22 side facing away.
- Fig. 5 shows this gas cooler 20 in section.
- the collecting box 21 is basically the same as in the embodiment according to Fig. 2 , but mirror-inverted.
- the collecting box 21 has two longitudinal chambers 21a, 21b, which are divided by a double longitudinal partition wall 25 from each other.
- the flat tubes 22 are inserted through a not visible here opening in the collecting box 21 so that they fill with their flat tube ends 22a about half of the longitudinal channels 21 a, 21 b.
- the upper edge 22b is thus at the height of the maximum width of the inner cross sections.
- the Flat tube 22. Skin has a continuous depth t, which extends into the collection box 21.
- Fig. 6 shows a section in the plane VI-VI through the longitudinal channel 21a in Fig. 5 ,
- the flat tubes 22 are inserted through corresponding openings 26 in the collection box 21, wherein the openings 26 extend over the full depth t of the flat tube 22.
- approximately circular notches 27 are arranged, which transition into a rectangular cross section corresponding to the flat tube cross section and thus allow the insertion of the flat tube ends 22a.
- an approximately circular gap 28 is left, which forms a passage cross section between the two longitudinal chambers 21a, 21b.
- no gap is left.
- the tongues 23 and also the not visible recesses here are each arranged between the flat tubes 22.
- Fig. 7 shows a third embodiment of a gas cooler 30 with a collecting box 31 and flat tubes 32.
- a double longitudinal partition wall 33 is anchored with tongues 34 in a central connecting portion 35, said connecting portion 35 is retracted slightly inward, ie by an amount x relative to a lower boundary line I of the header box 31 offset inwards.
- the cross sections of the longitudinal channels 36, 37 are approximated to the circular shape beyond the three-quarter circle (270 degrees). Nevertheless, the offset middle connecting region 35 and the double longitudinal dividing wall 33 form a right angle. This cross-sectional shape thus offers a higher compressive strength for the collecting box 31.
