Definitions

  • the invention relates to a heat exchanger, in particular for motor vehicle air conditioning systems according to the preamble of patent claim 1 .
  • Heat exchangers are frequently composed essentially of a heat exchanger network or tube/rib block and collecting tubes which are arranged on both sides.
  • the tubes of the heat exchanger network are usually flat tubes between which corrugated ribs are arranged in order to increase the size of the air-side heat exchanging face.
  • the flat tubes are accommodated by their ends in passages of the collecting tubes.
  • These parts of the condenser are first joined together mechanically and then soldered in an operation in a soldering oven.
  • the parts are often composed of an aluminum alloy and have solder plating on their surface.
  • many such heat exchangers have connecting tubes, i.e. for example a coolant inlet tube for the gaseous phase and a coolant outlet tube for the liquid phase of a coolant.
  • the connecting tubes are connected, for example by means of a flange, to the coolant lines of the coolant circuit of a motor vehicle air conditioning system. Hitherto, after the soldering process the coolant connecting tubes were soldered into corresponding openings in the collecting tube by hand, i.e. using a soldering flame, and the flange was also not mounted until after the soldering process, for example attached to a holding element which has already been soldered to the collecting tube in the soldering oven.
  • the problem with soldering additional parts to the heat exchanger in the soldering oven is to secure these additional parts so that they retain their predetermined position during the soldering process and after the soldering process the condenser is also dimensionally accurate with respect to these additional parts.
  • soldering devices which keep the parts to be soldered in the desired position. After the soldering, the soldering device must be removed. Such soldering devices are disadvantageous since they require additional mounting time and also consume energy as a result of their heating up.
  • the object of the present invention is to improve a heat exchanger of the type mentioned at the beginning to the effect that a holding element can be simultaneously soldered to the heat exchanger without a soldering device or similar resources and is soldered in its intended position after the soldering process.
  • the shape of the holding element is adapted to the external shape of the collecting tube.
  • the holding element is constructed with a C-shaped section, whose rounded shape is adapted to the rounded shape of the collecting tube and surrounds it. This results in soldering in the region of the contact face.
  • the C-shaped section is clipped to the collecting tube. This may be done by means of corresponding latching or clamping elements on the limbs of the C-shaped section. The holding element with the C-shaped section is therefore simply pressed onto the collecting tube from above during the mounting process and is then secured after the clipping process.
  • the collecting tube to be constructed in two pieces, that is to say from a bottom piece and a lid piece, which are soldered to one another by means of two longitudinal seams. Since the lid part and the bottom part overlap in the region of the longitudinal seams, a shoulder is provided in the region of the longitudinal edge. The C-shaped section engages with its limbs in this shoulder or is supported on this shoulder. This further improves the securing of the holding element, in particular if clipping takes place at the same time.
  • a flange for securing connecting tubes is attached to the collecting tube by means of the holding element, in particular by way of a web.
  • the holding element is preferably constructed in one piece with the flange, with the embodiment as an extruded section being particularly advantageous.
  • the holding element therefore does not need to be connected to the flange after the soldering process, for example by additional screws or rivets.
  • the flange is thus secured to the collecting tube by way of the holding element and can be soldered to the heat exchanger. This saves mounting time once more.
  • the connecting tubes are also attached to the flange and to the collecting tube so that these parts can also be soldered tight to the heat exchanger in one operation. This step also shortens the manufacturing time and reduces the fabrication costs.
  • an extruded flange with holding element which has a concave section with a longitudinal groove is secured to the collecting tube by means of a securing piece by caulking and clamping.
  • the holding element is in the shape of a plate-shaped web with bent side faces or limbs whose lower edges are adapted to the rounded shape of the collecting tube.
  • these bent limbs have a supporting function so that the holding element cannot tilt on the collecting tube during the soldering processes but is instead fixed.
  • a securing process is carried out by means of a positive fit in this embodiment of the holding element also.
  • the holding element has, on its lower edge a lug which is plugged into a corresponding slot in the collecting tube.
  • the holding element is embodied as an extruded part. This provides the advantage of a soldering face which is increased in size, i.e. the holding element can be loaded to a greater extent. Furthermore, the advantage of lower manufacturing costs compared to a pressed holding element is obtained.
  • the holding element has a C-shaped section with a central rib, i.e. as it were an E-shaped section.
  • the rib is plugged into a corresponding slot in the collecting tube and caulked—and in this way the holding element is secured and can be soldered in the soldering oven without further securing means.
  • the advantage is obtained of more accurate positioning of the holding element by means of a rib and a slot.
  • the holding element has a holding plate which adjoins the outside of the C-shaped section, that is to say is part of the entire extruded section.
  • the holding plate can be bent, curved or else have other shapes which are provided by extrusion within the scope of manufacture.
  • the holding plate it can have attachment bores or cutouts which are manufactured by further processing, for example by hole punching.
  • the C-shaped section forms, on its concave side, a soldering face in which grooves which are produced by extrusion are arranged.
  • the heat exchanger is embodied as a condenser and preferably soldered.
  • Heat exchanger tubes and ribs which form a tube/rib block are particularly advantageous in this context because of the ease of fabrication.

  • FIG. 2 shows the collecting tube 4 of the condenser 1 according to FIG. 1 partially in a perspective view.
  • the collecting tube 4 is constructed in two parts, i.e. it is composed of a lid 8 and a bottom 9 which has slot-shaped passages 10 for holding the flat tubes of the tube/rib block 2 .
  • the lid and bottom parts 8 , 9 which are each constructed approximately in the form of a half cylinder overlap in the region of two longitudinal seams 11 , 12 and thus form stepped longitudinal edges 13 , i.e. shoulders which run in the direction of the longitudinal edges 13 .

  • the figure shows the web 15 which is of flat design and forms the connection between the holding element 16 and block 14 and at the same time provides a certain degree of elasticity.

  • the figure shows that the C-shaped section of the holding element 16 engages around the lid 8 and is supported with its longitudinal edges 16 c, 16 b on the longitudinal edges 13 of the collecting tube 4 .
  • the flat end regions 21 a, 22 a engage around the collecting tube 4 and the bottom 9 and at the same time cause the holding element 16 to be clipped to the collecting tube 4 , which is however not illustrated in detail.
