Definitions

  • the invention relates to a heat exchanger, in particular a gas cooler for CO2 ' as a refrigerant, according to the preamble of claim 1.
  • Heat exchangers for air conditioning systems with R134a as the refrigerant consist of a heat exchanger network made of flat tubes and collecting tubes with a circular cross section arranged on both sides of the network. Such constructions were sufficient in strength for the pressures occurring in a condenser. With modern refrigerants such as CO2, however, there are considerably higher pressures that are no longer manageable with conventional heat exchanger designs. Extruded manifolds with increased wall thickness have therefore been proposed in WO 98/51983, a manifold consisting of four circular flow channels arranged next to one another. The production of such an extruded manifold is expensive because of the tools required for it.
  • header pipe Another type of header pipe was proposed in DE-A 199 06 289, a header pipe being constructed from extruded parts and having two circular flow channels for the refrigerant C02. With this construction too, at least part of the collecting pipe must pass through
  • the manifold is in two parts, i.e. made of a bottom and a lid, which consists of a bent sheet metal strip in the form of, for example, a W and forms two approximately circular flow channels with the bottom.
  • the lid and the base as well as the flat tubes inserted in the base are soldered together pressure-tight.
  • a longitudinal partition of the lid / bottom acts as a tie rod, - since it is soldered to the bottom / lid.
  • the edges of the cover, which overlap the base have individual tabs or tabs, which overlap the base in its edge region and thus cause the base and cover to be pre-fixed before the soldering process. There is therefore no longer any need for an additional soldering device to solder the heat exchanger.
  • An increased pressure stability is achieved if the bottom is concave.
  • the central web or the longitudinal partition wall has notches in the area of the flat tube ends, which allow the refrigerant to flow out of the flat tubes and the refrigerant to flow from one longitudinal channel into the other. As a result, there are diverse possibilities for flow control of the refrigerant, in particular in connection with transverse dividing walls.
  • the number of longitudinal channels of the collecting tank can be multiplied by the cross-sectional shape of the cover having a WW shape or a multiple W shape. This creates two additional longitudinal channels, ie a larger volume is made available for the refrigerant if necessary. It may also be advantageous to provide two or more rows of flat tubes instead of just one row of flat tubes.
  • FIG. 1 shows a perspective partial view of a single-row gas cooler
  • FIG. 2 shows a longitudinal section through the gas cooler according to FIG. 1
  • FIG. 3 shows a section along the line III-III in FIG. 2
  • FIG. 4 shows a second exemplary embodiment of a gas cooler with a shoulder in FIG 5, a longitudinal section through the gas cooler according to FIG. 4,
  • FIG. 6 a third exemplary embodiment of a double-row gas cooler with a four-channel collecting box, and
  • FIG. 7 a further perspective view of the gas cooler according to FIG. 6.
  • the gas cooler 1 shows a partial view of a condenser or gas cooler 1, as can preferably be used in an air conditioning system of a motor vehicle operated with the refrigerant CO2.
  • the gas cooler 1 has a heat exchanger network, of which only flat tubes 2 are shown here in part, the tube ends 2a of which are received by a base 3 of a collecting tank 4. Between the flat tubes 2 are not shown corrugated fins to enlarge the air-side heat exchange surface.
  • the collecting tube 4 also consists of a W or M-shaped cover 5, which engages behind the bottom 3 with tabs or tabs 6 arranged on the edge.
  • the W- or M-shaped cover is formed so 'that a longitudinal partition is formed such that areas of the lid touch and are soldered together. This creates a double-walled partition.
  • the bottom can also show the partition.
  • FIG. 2 shows a section through the gas cooler 1 according to FIG. 1, namely in parallel between two flat tubes 2.
  • the W or M shape of the cover 5 which is bent from a sheet metal strip and which has two outer edge regions 7 , 8 and has a central web 9 which is designed as a fold and which extends in the longitudinal direction of the collecting tank
  • the bottom 3 is concave, ie curved outwards.
  • the central web 9 has a web back 12, the entire surface resting on the bottom 3 and is soldered thereto to form a 'tension rod.
  • FIG. 3 shows a section along the line III-III in FIG. 2, the flat tubes 2 being hatched in a simplified representation.
  • the flat tubes 2 have a multi-channel cross section, which is produced by extrusion.
  • the flat tube ends 2a are received in corresponding openings 3a in the base 3 and protrude into the interior of the longitudinal channels -10, 11. In this area - around the flat tube ends 2a - is the
  • the gaps 15 thus form overflow openings between the two longitudinal channels 10, 11.
  • FIG. 4 shows a second embodiment of a gas cooler 16 having a W-shaped cover '17 and a flat bottom 18.
  • FIG. 5 shows a longitudinal section through the gas cooler 16 according to FIG. 4.
  • the cover 17 has two edges 19, 20, on the inside of which shoulders 21, 22 are formed, which serve as an attachment for the bottom 18.
  • the bottom 18 is gripped by tabs 23, 24 which protrude from the edges 19, 20.
  • FIGS. 6 and 7 show a third exemplary embodiment of a gas cooler 25 with two rows of flat tubes 26, the ends of which are received by a flat bottom 27 of a collecting box 28.
  • the latter has a lid 29 which is bent and folded from a sheet metal strip and which has the shape of a double W, i. H. has three central webs 30 which divide the collecting box 28 into four longitudinal channels 31.
  • this cover 29 also has shoulders 32 for the contact of the base 27, which is also fixed by rags 33.
  • This multichannel design creates a larger volume for the header tank 28 and at the same time ensures the pressure stability required for the high internal pressures.
