Definitions

  • the invention relates to the field of heat exchangers and more particularly to flat-tube heat exchangers in the field of automobiles.
  • heat exchangers comprising a stack of identical flat tubes in which a first fluid flows.
  • Each flat tube is formed of two plates of metal sheet stamped to form a bowl in a predefined pattern and arranged in such a way that their concavities are turned towards each other.
  • the two plates are then connected in a sealed manner, thus forming a flat tube in which a fluid can flow from a fluid inlet to a fluid outlet each located at one end of the flat tube, and more generally each located on opposite sides of the tube. the plaque.
  • the flat tubes are stacked on each other, the fluid inlets of each flat tube being connected together to form an inlet column. Similarly, the fluid outlets of each flat tube are interconnected to form an output column. Between each flat tube is left a space for the passage of a second fluid.
  • the exchange of heat between the two fluids thus occurring during the passage of the first fluid in the flat tubes and the second fluid between said flat tubes. It is also known to increase the length of the flat tube and therefore the exchange surface between the two fluids, to follow the flat tube a tortuous circuit retaining ribs on the plates during stamping.
  • the input and output columns can thus be positioned on opposite sides of the plates or on the same side of the plates, as shown in the EP2105694 application.
  • Such heat exchangers are commonly used as an evaporator in a refrigerant circuit for the air conditioning of the passenger compartment of a motor vehicle, this refrigerant constituting the first fluid and the second fluid being atmospheric air, or as a radiator. heating in a coolant circuit for heating the passenger compartment of a motor vehicle, the heat transfer fluid constituting the first fluid and the second fluid being atmospheric air.
  • An object of the invention is therefore to at least partially overcome the disadvantages of the prior art and to provide a heat exchanger limiting the pressure losses of the plates.
  • the present invention thus relates to a plate for a heat exchanger flat tube made from a stamped metal sheet, said stamping allowing the connection between a fluid inlet and a fluid outlet, said plate having a length L and a width 1, said fluid inlet and outlet being located along the length at a distance from the edge of the plate corresponding to L / 2, plus or minus 40mm and the stamping forming a first fluid flow passage located on a first side of said fluid inlet and outlet and a second fluid flow passage located on a second opposite side at the first, said fluid inlet and outlet.
  • the first and second fluid flow passages are symmetrical with respect to one another along an axis of symmetry passing through the fluid inlet and outlet, parallel to the width of said plate .
  • the stamping comprises ribs giving the first and second passages a sinuous path comprising half-turns between the fluid inlet and the fluid outlet.
  • the ribs have rounded ends.
  • the first and second fluid flow passages comprise disturbance projections.
  • the length of said plate is greater than or equal to 400mm.
  • the invention also relates to a flat tube for a heat exchanger comprising at least one plate according to the preceding aspects.
  • the flat tube for heat exchanger comprises a first and a second plate according to the preceding aspects.
  • the invention also relates to a heat exchanger comprising at least one flat tube according to the preceding aspects.
  • said heat exchanger is a charge air cooler.
  • FIG. 1 shows a schematic representation of a plate for a heat exchanger flat tube
  • FIG. 2 shows a schematic representation of a heat exchanger with a cooling circuit of a fluid.
  • Plate ⁇ for flat heat exchanger tube shown in Figure la a length L and a width h.
  • the plate 1 made from a pressed metal sheet, has a fluid inlet 3a and a fluid outlet 3b located on the length L at a distance from the edge of the plate 1 corresponding to L / 2, more or less 40mm.
  • the fluid inlet 3a and fluid outlet 3b are located at the center of the length L of the plate 1.
  • the stamping of the plate 1 forms a cavity with ribs 7 defining a first and a second passage 5a and 5b of fluid flow between the fluid inlet 3a and the fluid outlet 3b.
  • the ribs 7 give the first and second passages 5a, 5b a sinuous path having half-turns between the fluid inlet 3a and the fluid outlet 3b.
  • This sinuous path allows an increase in the length of the first and second passages 5a, 5b and therefore increases the time during which the fluid flows in said first and second passages 5a, 5b, thereby increasing the time or it can have heat transfer from one fluid to another.
  • the ribs 7 may have rounded ends 11.
  • the first and second fluid flow passages 5a, 5b are symmetrical with respect to each other along an axis of symmetry passing through the fluid inlet and outlet 3a, 3b and parallel to the width h of said plate 1 That is, they are identical to each other and have the same shape and length.
  • the flow passages 5a, 5b may also include disruption projections 9 to make the fluid flowing in the flow passages 5a, 5b more homogeneous.
  • the flat tubes are constituted by the assembly of two plates 1 between them, the flow passages 5a and 5b of each of the two plates facing each other.
  • the assembly of the plates 1 is made to be tight, to prevent leakage of the fluid passing through the flow passages 5a, 5b.
  • a flat tube heat exchanger comprises a stack of flat tubes interconnected at their fluid inlet and outlet 3a, 3b, and each flat tube being spaced apart to allow another fluid to pass between said flat tubes.
  • the flat tubes are connected to each other at the fluid inlet and outlet 3a, 3b in order to form a fluid inlet column comprising all the fluid inlets of all the flat tubes and a fluid outlet column comprising all the outlets. of fluid from all the flat tubes.
  • the fluid inlet and outlet columns are located in the center of the heat exchanger.
  • This configuration makes it possible to have only one refrigerant inlet column 30a and a single refrigerant outlet column 30b and thus to overcome the constraints and costs associated with the use of two heat exchangers. and therefore requiring two coolant inlet columns and two coolant outlet columns.
