Definitions

  • the invention relates to a heat exchanger, in particular for an internal combustion engine, according to the preamble of claim 1.
  • This object is achieved according to the invention for a heat exchanger mentioned above with the characterizing features of claim 1.
  • the number of rich is exactly four. It has been found that a very large number of rows entail an increasing expense in the cascading of the heat exchanger and the reject rates are higher. An optimal number of rows of tubes with simultaneously large depth of the net and low rejects is optimally achieved by the number of four rows of tubes,
  • an aluminum-based heat exchanger according to the invention is formed, for example from solder-plated aluminum sheets. This is done regularly a cassitation of the flat tubes and floors, depending on the embodiment, together with aluminum boxes for Vervoli direction of the collector. This cassetted or mechanically pre-assembled unit is placed in a soldering oven and soldered to a cohesively connected, fluid-tight heat exchanger,
  • all of the flat tubes of a row are each in alignment with a flat tube of a subsequent or preceding row. This results in an optimal utilization of the space and a particularly simple and effective way of arranging ribs between the flat tubes.
  • a maximum depth of the plurality of flat tubes in the main flow direction is at least as large as a maximum width of the flat tubes transverse to the main flow direction. This also includes the possibility of a substantially square cross-section of the pipe network with a. In an alternative embodiment, depending on requirements, it may be provided, however, that a maximum depth of the plurality of flat tubes in the main flow direction is smaller than a maximum width of the flat tubes transversely to the main flow direction.
  • the flat tubes have at least one subdivision running in their longitudinal direction, in particular in the form of a bead-like indentation. In this way, an improvement in the heat exchanger performance and / or an increase in pressure resistance is generally ensured.
  • the passages have at least one projection corresponding to the indentation. In addition to the task of sealing between passage and inserted flat tube can be ensured by the projection also a particularly good guidance and support in the course of Kassett ist.
  • a heat exchanger according to the invention may, depending on requirements, preferably be a coolant cooler or a charge air cooler of an internal combustion engine. It may also preferably be an evaporator of an air conditioner or condenser / gas cooler of an air conditioner.
  • a preferred embodiment of a heat exchanger according to the invention comprises a unit cassetted from solder-plated aluminum sheets and flat tubes, which is soldered in a material-locking manner in a soldering furnace,
  • Fig. 1 shows as a central component a bottom 1 of this heat exchanger. Not shown are a box, through which the bottom 1 is completed to a collector, and the inserted into the bottom 1 flat tubes.
  • the flat tubes (not shown) are formed as folded tubes of a solder-clad aluminum sheet, each having a central recess for forming a web for dividing the flat tube into two chambers. Alternatively, the flat tubes may also be formed as extruded profiles.
  • passages 2 are introduced in the form of punched, slot-shaped openings.
  • the passages 2 have at their center in each case symmetrically from the edge outgoing projections 2a, which correspond to the (not shown) indentation of the flat tubes.
  • a lowering direction T which is at the same time the main flow direction of a fluid flowing around the flat tubes
  • four rows a, b, c, d of flat tubes are arranged one behind the other.
  • the stacking direction of a respective row of the flat tubes runs the width direction B and in the direction of the longitudinal extent of the flat tubes or, perpendicular to the plane of the bottom 1 extends the longitudinal direction L.
  • Each of the rows a, b, c, d comprises a stack of exemplarily fourteen flat tubes which extends in the transverse direction or in the width direction B of the heat exchanger.
  • Recognizable are all of the flat tubes of one of the rows a, b, c, d respectively in alignment with a flat tube of a subsequent or a previous row a, b, c, d.
  • the longitudinal sides of the flat tubes extend parallel to the depth direction T.
  • All of the flat tubes form the net of the heat exchanger.
  • the exchange network is present in the depth direction T longer than in the width direction B (see in particular Fig. 2 ), so that a maximum depth TM in the plurality of flat tubes in the main flow direction is larger than a maximum width BM of the flat tubes transverse to the main flow direction T.
  • each of the rows a, b, c, d is surrounded by an embossed edge 3, whereby the rigidity of the bottom 1 is improved.
  • the bottom of the embodiment shown is the bottom of a coolant radiator, wherein the flat tubes are flowed through by the coolant and are surrounded by cooling air such as wind.
  • it may also be a charge air cooler or another heat exchanger, in particular for an internal combustion engine.
