Definitions

  • the present invention concerns a heat exchanger tube, a heat exchanger including such tubes and a method of producing such a tube.
  • the heat exchangers concerned are intended for equipping vehicles and, in a preferred application, correspond to the condensers provided in the air conditioning loops or circuits of the vehicles. There may nevertheless be envisaged, without departing from the scope of the invention, an application of these exchangers as radiators in engine cooling loops or circuits.
  • the air conditioning loop of the passenger compartment of a vehicle generally consists primarily, in the direction of flow of the coolant fluid (for example freon, CO 2 , 1234YF fluid) passing through it, a compressor compressing the fluid at this point in the form of vapor, a condenser receiving the fluid to convert it to liquid form thanks to a flow of external air sweeping it, an expander reducing the pressure and an evaporator, in which the expanded and condensed fluid exchanges heat with a flow of external air to be directed into the passenger compartment.
  • the fluid is converted to the vapor phase at the outlet of the evaporator to be fed into the compressor for a new cycle, while the flow of external air passing through the evaporator is cooled to supply conditioned air in the passenger compartment.
  • the condenser forming the heat exchanger includes a bundle of parallel tubes and two manifolds (or collector boxes) into which the corresponding ends of the tubes are fixedly connected in sealed manner, by brazing them. Accordingly, the coolant fluid in the loop is able to flow through the tubes, the fluid being converted from its vapor phase to its liquid phase by the flow of external air sweeping the tubes.
  • the invention relates to heat exchanger tubes produced using the bending technology.
  • Such tubes are generally produced from a spool of sheet metal which, after it is paid out in strip form, is progressively shaped to the required cross section by dedicated bending tools or the like, and then cut to the required length, in sections corresponding to the finished tubes.
  • the heat exchanger tubes may be subjected to numerous loads such as a high-speed impact with an object (for example a stone) from the exterior environment.
  • the tube must be able to withstand any such impact so as to prevent any leaking of fluid.
  • the tube In the case of a bent tube, the tube cannot be reinforced by an increased thickness of material as is the case for an extruded tube. It is however necessary to increase the thickness of the wall of the bent tube locally as the latter thickness is generally around 0.2 mm, which is insufficient from the point of view of withstanding stone impacts.
  • the wall of the tube is bent horizontally on itself several times at the level of one side or nose of the tube, increasing the thickness of material in the tube nose.
  • a drawback is that the height of the tube is thus a function of the thickness of material thereof and corresponds to the number of bends.
  • the tube is open beforehand along one of its sides that is then closed by overlapping plane on plane two thicknesses of wall.
  • a drawback of a solution of this kind is the risk of defective sealing at the level of the side closed in this way.
  • the patent DE102006006670 describes a solution including sides having numerous vertical bends. A major drawback of this solution is that it leads to excess consumption of material.
  • tubes with an internal separator there are also known, notably from the patent DE102005043093, tubes with an internal separator.
  • a tube and an internal separator it is not possible to proceed to cut the tube and the internal separator to length with conventional means (for example cutting with a knife), because the internal separator tends to be compressed during this operation.
  • the tube is first shaped and then cut to length, the internal separator is also shaped and then cut to length, and the tube and the internal separator are then assembled. In this configuration it is necessary to leave a functional clearance between the tube and the internal separator to be able to insert the latter. This clearance is not favorable for correct brazing of the components to each other.
  • An object of the present invention is to remedy these drawbacks and the present invention concerns a fluid circulation tube the design of which enables the internal separator to reinforce the tube and notably at least one side of the tube.
  • the heat exchanger tube comprises a bent wall defining a housing and an internal, for example corrugated, separator inserted into the housing.
  • the internal separator defines a plurality of fluid circulation channels.
  • the wall of the tube has large surfaces connected by radii.
  • the internal separator extends in the lengthwise direction, for example, from one orifice to the other of the tube.
  • the large surfaces are notably plane and parallel to each other.
  • the tube is configured so that the clearance between the wall and the internal separator is filled along the length of at least one radius.
  • the clearance between the internal separator and the wall of the tube is filled along the radius, over all or part of the length of the internal separator. The effect of this is to increase the overall area of contact between the separator and the walls of the tube, and therefore the thickness of the tube, at least at the level of the nose of the tube.
  • the internal separator includes at least one flat at one apex, said flat being in contact with the wall. This has the advantage of increasing the mechanical strength, including at the level of its plane faces.
  • the internal separator includes a flat at each of its vertices, said flat being in contact with the wall.
  • the tube is configured so that the clearance between the wall and the internal separator is filled along each radius. This has the advantage of reinforcing the tube noses on each side of the tube and thus avoiding the necessity to mark the reinforced side.
  • the tube has a section in the shape of a B and said wall comprises legs that meet at the level of a central portion of said B-shaped section. At least one of said legs is in contact with the internal separator. This has the advantage of increasing the mechanical strength of the tube.
  • the invention also concerns a heat exchanger that includes tubes as defined above.
  • the heat exchanger with these fluid circulation tubes preferably defines the condenser of a motor vehicle air conditioning loop or the like.
  • a heat exchanger finds a particular application in the field of motor vehicles, for example to produce an air conditioning condenser.
  • the exchanger has the structure referred to above, for example.
  • the invention also concerns a method of producing a heat exchanger tube, in particular the condenser of a motor vehicle air conditioning system.
  • the tube comprises a bent wall defining a housing and an internal separator, which is for example corrugated, inserted into the housing with a clearance.
  • the internal separator defines a plurality of fluid circulation channels and the wall of the tube has large surfaces, notably plane surfaces, of length L connected by radii of height H.
  • the method comprises the steps of inserting the internal separator in the housing and compressing the tube in the direction of its height.
  • the compression is characterized in that it compresses the tube from a height H 1 to a height H 2 with H2 ⁇ H1 and from a length L 1 to a length L 2 with L1 ⁇ L2, so that the clearance between the wall and the internal separator is at least partially filled.
  • the compression By compressing the tube from a height H 1 to a height H 2 with H2 ⁇ H1 and from a length L 1 to a length L 2 with L1 ⁇ L2, the compression enables the overall area of contact between the insert and the walls of the tube to be increased, notably at the level of at least one tube nose. This has the advantage of enabling better brazing between the internal separator and the walls of the tube in contact with the internal separator.
  • Another advantage of the method of the invention is that the compression (i.e. deformation) enables linear and homogeneous reshaping of the tube including the internal separator.
  • the method includes a preliminary step wherein the wall of the tube is produced by bending a sheet of material, for example, and has, after bending, a substantially closed section in which the internal separator is inserted.
  • the compression is exerted in a direction substantially orthogonal to the plane faces of the tube.
  • the compression step is configured so that the tube and its components, wall and/or insert, have the features referred to above.
  • FIG. 1A represents a tube bent into the shape of a B before compression in accordance with one embodiment of the invention and including an internal separator inserted between the walls of the tube.
  • FIG. 1B represents the tube from FIG. 1A after compression.
  • a heat exchanger tube 100 notably of an air conditioning condenser for motor vehicles, comprises a bent wall 105 , defining a housing 115 , and an internal separator 130 , inserted in the housing.
  • the internal separator 130 which is notably corrugated, defines a plurality of fluid circulation channels 136 .
  • the wall 105 has large, for example plane, surfaces connected by radii 110 .
  • the wall of the tube notably has a cross section in the shape of a B.
  • This inner spacer or each of these inner spacers notably also has the function of improving the thermal performance of the condenser and the mechanical strength of the tubes, which must resist not only the operating pressure when the loop is operating, which is of the order of 20 bar, but also that imposed by the specification, notably a tube bursting rating of up to 100 bar, for coolant fluids based on freon.
  • the tube 100 is configured so that the clearance is filled along at least one radius 110 between the wall 105 and the internal separator 130 .
  • the clearance is defined by the space that exists between the internal radius of the radius 110 of the tube 100 and the curvature of the end 134 of the internal separator 130 . This means that the contact is continuous so that the clearance between the wall 105 and the internal separator 130 is entirely filled over all the length of the radius (i.e. along all the curvature of the radius).
  • the tube is configured so that the clearance between the wall 105 and the internal separator 130 is for example filled along each radius 110 .
  • the internal separator 130 includes at least one flat at a vertex 132 , notably at each vertex 132 , said flat being in contact with the wall.
  • the tube 100 has, for example, a section in the shape of a B and the wall has legs 120 joined at the level of the central part of said B-shaped section, at least one of the legs 120 being in contact with the internal separator 130 .
  • the tube 100 comprises a wall 105 defining a housing 115 and an internal separator 130 inserted in the housing 115 .
  • the internal separator 130 defines a plurality of fluid circulation channels 136 .
  • the wall has large, notably plane, faces of length L connected by radii of height H.
  • the length L corresponds to the dimension of the tube 100 in the direction of its longitudinal section.
  • the height H corresponds to the overall thickness of the tube 100 , i.e. its thickness in the direction of its cross section.
  • the tube extends along its longitudinal axis, orthogonal to the plane of FIGS. 1A and 1B .
  • the method of the invention includes a first step in which the internal separator 130 is inserted into the housing 115 of the tube 100 with a clearance.
  • the method of the invention includes a second step in which the tube 100 is compressed in the direction of the height H.
  • This compression is characterized in that it enables the tube to be compressed from a height H 1 to a height H 2 with H2 ⁇ H1 and from a length L 1 to a length L 2 with L1 ⁇ L2, the tube 100 being configured after compression so that the clearance between the wall 105 and the internal separator 130 is at least partially filled.
  • the compression step may be generalized to a deformation step without limiting the scope of the protection of the present invention.
  • the compression or deformation step enables the wall 105 and the internal separator 130 to be calibrated.
  • This step enables reshaping of the tube 100 , the dimensions of which are modified.
  • the dimensions of the wall 105 and the internal separator 130 can be defined beforehand so that this clearance exists despite the manufacturing tolerances of the two parts.
  • a reshaping dimension is then defined in order to calibrate the tube 100 and the internal separator 130 and to fill at least one clearance or even all of the clearances provided for the purpose of this insertion.
  • the compression step enables the height H to be reduced and the length L to be increased.
  • the effect of this is to fill the clearance along the radius between the wall 105 and the internal separator 130 and to enable brazing of the components.
  • the increase in the dimension L of the wall 105 will be less than that of the internal separator 130 .
  • the compression step makes it possible to increase the length dimension L of the internal separator 130 more than that of the wall 105 .
  • This makes it possible to fill the assembly clearance between the internal separator 130 and the inside radius of the tube nose 110 .
  • This moreover makes possible the brazing of the two components (i.e. wall 105 and internal separator 130 ) and thus to increase the mechanical strength, notably at the level of the tube nose 110 .
  • the method could include a preliminary step in which the wall of the tube is produced by bending a sheet of material, for example, and after bending has a substantially closed section into which the internal separator is inserted.
  • the compression is exerted in a direction substantially orthogonal to the plane faces of the tube.
  • the compression step is configured so that the tube and its components, wall and/or internal separator, have the features referred to above, for example.
  • the compression step could be configured so that, after compression, the internal separator 130 includes a flat at one at least of its vertices 136 , said flat being in contact with the wall.
  • the compression step thus enables the production of the plane areas at some or all of the vertices 136 of the internal separator 130 .
  • the consequences of the reduction in the height are crushing of the internal separator 130 generating a flat at its vertex and, depending on the magnitude of the calibration, modifying the angles of the bends of the internal separator 130 .
  • the effect of this is to guarantee the brazing between the internal wall of the wall 105 and the internal separator insert 130 as well as to increase the mechanical strength of this combination.
  • the compression step could also be configured so that the clearance between the wall 105 and the internal separator 130 is filled along each radius 110 .
  • the compression step could further be configured so that, after compression, at least one of said legs 120 is in contact with the internal separator 130 .
