Definitions

  • the present invention relates to a heat exchanger, in particular for a motor vehicle.
  • EP 2 746 561 A1 discloses a heat exchanger according to the preamble of claim 1.
  • Heat exchangers are used, for example, in motor vehicles to cool the fresh air charged by means of an exhaust-gas turbocharger in a fresh-air system interacting with the internal combustion engine of the motor vehicle.
  • the fresh air to be cooled is introduced into the heat exchanger, where it interacts thermally with a likewise introduced into the heat exchanger coolant and emits heat in this way to the coolant.
  • Such a heat exchanger may be configured, for example, as a plate heat exchanger and having a plurality of plate assemblies each having a pair of plates stacked in a stacking direction, wherein between the plates of a pair of plates a fresh air path is formed through which the fresh air to be cooled is passed.
  • the aforementioned coolant can be fluidically separated from the fresh air to be cooled, which can be set in thermal interaction with the fresh air to be cooled by the plates of the plate arrangement .
  • rib structures may be provided between adjacent plate assemblies which increase the interaction area of the plates available for thermal interaction. Such constructions are known to those skilled in the art by the term "fin-tube heat exchanger".
  • a heat exchanger comprises a plurality of channel devices for flowing through with a first fluid, which are arranged adjacent to one another along a stacking direction.
  • each channel device has a pair of plates with a first and a second plate, which define in the stacking direction a first fluid channel for flowing through the first fluid.
  • the term "plate” is intended to be used herein in a broad sense and includes in particular any type of substantially flat design components. Also plates with on this, in particular sections, trained three-dimensional structures and pot-shaped plates are expressly included in the term "plate” used here.
  • Two adjacent channel devices in the stacking direction are arranged at a distance from one another, so that a second fluid channel for flowing through a second fluid, which is fluidically separated from the first fluid channel, is formed by the intermediate space formed between the two channel devices.

  • inventive arrangement of the individual channel elements causes the channel housing of the channel elements can be advantageously almost completely surrounded by the first fluid, preferably the air to be cooled. This leads to a comparison with conventional heat exchangers thermal interaction of the first fluid with the flowing through the individual channel elements second fluid, that is preferably a coolant. As a result, this leads to a heat exchanger with improved efficiency.
