Definitions
- the invention relates to the field of heat exchangers and charge air heat exchangers in the field of automobiles, in particular a flat tube of charge air heat exchanger according to the preamble of claim 1. .
- WO 2009/156365 describes such a tube.
- Each flat tube is generally 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 the first 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 plate.
- 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.
- 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 fluid circuit coolant for heating the passenger compartment of a motor vehicle, the heat transfer fluid constituting the first fluid and the second fluid being atmospheric air.
- the use of a liquid as the first fluid has the disadvantage of reducing the resistance of the exchanger over time, because it is more likely to be damaged by corrosion.
- one of the aims of the invention is to at least partially overcome the disadvantages of the prior art and to provide an improved supercharging air heat exchanger.
- the present invention therefore relates to a flat tube of charge air heat exchanger made from at least one pressed metal sheet so as to form an exchange plate, said stamping allowing the connection between a fluid inlet and a fluid outlet by a circuit in which a coolant circulates, said circuit comprising at least one metal insert placed therein and made of a material creating a potential difference greater than or equal to 30mV with the material of the flat tube.
- the flat tube is formed by the assembly of two exchange plates made from a stamped metal sheet and assembled to one another, the stamped sides of each plate of exchange facing each other.
- the insert is made of metal alloy comprising 0.7 to 1.5% of zinc.
- the at least one exchange plate is made of 3000 series aluminum alloy and the insert is made of aluminum alloy 6815 or 6807.
- the invention also relates to a charge air heat exchanger comprising at least one flat tube as described above.
- the exchange plate 1 for flat tube 100 of heat exchanger, shown in FIG. figure 1 can be made from a stamped metal sheet. It comprises a fluid inlet 3a and a fluid outlet 3b.
- the stamping of the exchange plate 1 forms a cavity with ribs 7 defining a fluid flow circuit between the fluid inlet 3a and the fluid outlet 3b.
- the ribs 7 give the flow path a flow path of a first heat transfer fluid between the fluid inlet 3a and the fluid outlet 3b.
- This circulation path comprises at least two straight passes 5 connected by a curved portion 9.
- This circulation path allows an increase in the length of the flow circuit and therefore increases the time during which the first heat transfer fluid flows within it. , thereby increasing the time when there can be heat transfer with a second fluid flowing on the opposite side of the exchange plate 1.
- the ribs 7 may have rounded ends 11 .
- the exchange plate 1 has four passes 5 parallel to each other and three curved portions 9 making the connection between said passes 5.
- the at least one curved portion 9 may comprise projections 91.
- These protrusions 91 may be made of material with the at least one exchange plate 1, for example by being made by stamping, or even be attached elements and fixed to within the at least one curved portion 9 by any means known to those skilled in the art.
- the flat tubes 100 are generally constituted by the assembly of two exchange plates 1 between them, the passes 5 and curves 9 of the circuits and the ribs 7 of each of the two exchange plates 1 facing each other, forming the path of circulation of said flat tube 100.
- the assembly of the exchange plates 1 is made to be sealed, for example by soldering, in order to prevent any leakage of the coolant passing through the flat tube 100.
- Such flat tubes 100 are relatively thin for example their circulation path can have a height of 1mm to 3mm.
- a flat tube 100 may be the assembly of an exchange plate 1 with a flat plate resting on the periphery of the exchange plate 1 and on the ribs 7, covering the circuit of FIG. flow.
- the circuit comprises at least one insert 51 intended to disturb the circulation of the first heat transfer fluid and creating turbulence, as well as increasing the contact surface with the first heat transfer fluid and therefore increase exchanges between said first fluid and the flat tube 100.
- the at least one insert 51 is made of a metallic material creating a potential difference greater than or equal to 30mV with the material of the flat tube 100. This potential difference allows said insert to be a sacrificial anode which is corroded preferentially instead. of the material of the flat tube 100, the latter in fact acquiring better resistance to corrosion over time.
- said insert 51 is an effective sacrificial anode
- said insert can be made of a metal alloy comprising 0.7 to 1.5% of zinc.
- the insert 51 may have a corrugated conformation perpendicular to the direction of flow of the first heat transfer fluid, the ends of each corrugation being in contact with the walls of the flat tube 100.
- the insert 51 may also have, parallel to the flow direction of the fluid coolant in the flat tube 100, series of corrugated sections, offset relative to each other perpendicular to the direction of circulation of the coolant.
- the first heat transfer fluid then passes between the corrugations of each section, increasing the contact and exchange surface between the fluid and the walls of the flat tube 100, and during the passage from one corrugated section to another, the first heat transfer fluid undergoes a disturbance allowing homogenization of the temperature and therefore a better heat exchange efficiency with the flat tube 100.
- said insert 51 may also have other conformations allowing an increase in the contact surface as well as a homogenization of the fluid such as for example crenels, zigzags or slats.
- a flat-tube heat exchanger 100 comprises a stack of flat tubes 100 interconnected at their fluid inlet and outlet 3a, 3b, and each flat tube 100 being spaced to allow passage of a second fluid between said flat tubes 100.
- the flat tubes 100 are interconnected 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 100 and an outlet column. of fluid comprising all the fluid outlets of all the flat tubes 100.
- the use of inserts 51 as inserts 51 in the passes 5 of the flat tubes 100 allows the latter to have a smooth wall and thus facilitates the fixing, for example by brazing, disrupters 102 in space between two flat tubes 100.
- the flat tube 100 due to the presence of a metal insert 51 made of a material creating a potential difference greater than or equal to 30mV with the material of the flat tube 100 and acting as a sacrificial anode , has a better resistance to corrosion, especially from the first fluid and therefore has a longer life.
