Definitions

  • the present invention relates to a heat exchanger.
  • the invention relates to a heat exchanger having tubes brazed to wall of a housing of the heat exchanger.
  • the heat exchangers are provided in a vehicle for various operations.
  • charge air coolers are provided in air inlet circuit of an engine.
  • the engine may receive air from atmosphere and the atmospheric pressure decreases with the change in elevation of the vehicle, i.e., while the vehicle traveling in elevated area such mountain regions. In such case, the fuel economy and thermal efficiency of the engine may be reduced as the engine may receive inefficient amount/pressure of air.
  • air is pressurized (herein referred to as the "charge air") by mechanical or electric compressors, known as superchargers or turbochargers. In the forced induction engines, power output becomes a function of how much air is delivered to the cylinders.
  • the charge air cooler is provided in the upstream to the engine and downstream to the turbo/super-charger.
  • the charge air cooler may dissipate heat from the charged air flowing from the turbo-charger.
  • the charge air cooler is equipped with a set of tubes forming a heat exchange bundle between a first fluid and a second heat transfer fluid, and the heat exchange bundle being housed in a casing.
  • the tubes in the charge air cooler can be made of aluminum as it offers significant weight savings, and aluminum alloys also have good thermal and corrosion resistance. Due to the complexity of the charge air cooler and the small dimensions allowed, the components of the charge air coolers are assembled by brazing. Further, the tubes are typically brazed to the housing of the charge air cooler, i.e. joined by adding liquid metal to the metal parts to be joined. As these tubes are brazed over their entire surface in contact with the walls of the housing, the metal thus added forms a continuous line, thereby the assembly lacks in flexibility. It is well known that the charge air coolers are subjected to high and varied stresses during operational mode, such as thermomechanical stresses and chemical reactions with more or less aggressive environments.
  • thermal shocks caused by a sudden and significant change in temperature, for example when opening valves equipped with sensors that measure engine temperature and allow cold engine cooling water to pass into the warmer engine air intake system.
  • thermal shocks lead to expansion/contraction phenomena of the tubes of heat exchanger, called thermal cycles.
  • the lack of flexibility of tubes generates significant stresses, which can lead to the appearance of rupture zones in tubes. It can then be observed that these fracture zones can lead to leakage of the heat transfer fluid.
  • the heat exchange tubes may include some breakable tabs between the tube and the housing which are intended to crack during thermal cycle.
  • the breakable tabs tend to form unpredictable shapes and structures which in most cases would cause collision between the housing and the tube, especially during expansion of the tubes. Such collision may lead to mechanical stress, and finally, to malfunction of the charge air cooler due to leakage.
  • the present invention therefore aims to compensate for the disadvantages of the previous art and to meet the above-mentioned constraints by proposing a tube for heat exchanger, simple in its design and in its operating mode, reliable and economical, which makes it possible to limit, or even avoid, the appearance in the tube of rupture zones linked to thermal shocks, and collision between the remaining elements of the breakable fuse element.
  • Another object of the present invention is such a tube for a heat exchanger providing a support on the opposite walls of the casing with a view to its assembly by brazing with a complementary tube to form a conduit for the circulation of a heat transfer fluid.
  • the present invention is also intended for a heat exchanger comprising at least one such tube for an exchanger, so as to present enhanced reliability.
  • the invention concerns a tube for a heat exchanger, said tube comprising a coupling edge to another tube.
  • said edge comprises at least one fusible part for assembling this coupling edge with at least one housing wall, said at least one fusible part being configured to be separated from the rest of said coupling edge by differential expansion/contraction between said tube and said at least one housing wall on which it is intended to be assembled.
  • some elements or parameters may be indexed, such as a first element and a second element.
  • this indexation is only meant to differentiate and name elements which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.
  • the present invention relates a tube for a heat exchanger.
  • the tube includes at least one fusible part formed on at least one coupling edge of the tube for assembling with at least one wall of the heat exchanger. Further, the fusible part is parallelly aligned with respect to a general plane (P1) of the tube.
  • the tube is a flat tube assembled of two half-plates so that it comprises two flat walls joined along at least two coupling edges, wherein the two coupling edges define a general plane.
  • the tube further includes a base portion located in the vicinity of the coupling edge and a tip portion located in the vicinity of the wall of the heat exchanger. The tip portion of the fusible part is adapted to be entirely separated from the wall by differential in expansion and contraction between the tube and the wall.
  • the tube further includes at least one notch located on the corner area of the tube, in particular the notch being located between the coupling edge and base portion of the fusible part.
  • the tip portion of the fusible part extends beyond the coupling edge of the tube.
  • the fusible part is formed at the corners of the coupling edge of the tube.
  • the tip portion of the fusible part is narrower than the base portion to facilitate separation of the tube from the wall.
  • the coupling edge is formed to delimit the tube formed by two plates assembled with each other with their respective opposite faces.
  • the coupling edges are intended to delimit a conduit for the circulation of a heat-transfer fluid within the tube.

  • the fusible part is thinner than half the thickness of the tube, wherein the thickness is measured in a direction perpendicular to the general plane (P1) of the tube.
  • the present invention may disclose a heat exchanger tube having at least one fusible part provided in a heat exchanger.
  • the heat exchanger may include bundle of tubes disposed between two manifolds and forming a fluid channel.
  • the tubes may be brazed to the inner wall of a housing of the heat exchanger.
  • the tubes may undergo various thermal cycle.
  • thermal stress may act on the tubes, which may lead to the appearance of rupture zones in the tubes.
  • fracture/rupture zones can lead to leakage of the heat transfer fluid.
  • tabs are provided at a coupling edge of the tube of the heat exchanger. Such tabs can be fusible part adapted to break when there is a differential expansion and contraction between tubes and corresponding wall of the heat exchanger.

  • the manifold 140 may be located parallelly with respect to the third wall 130 and perpendicularly with respect to the first and the second walls 110, 120, so that, similarly to the third wall 130, the opposite edges of the manifold 140 are in contact with the first wall 110, as well as the second wall 120.
  • the walls 110, 120, 130 and the manifold 140 may be joined together, e.g. by brazing, so that the walls 110, 120, 130 and the manifold 140 form an essentially rectangular fluid tight housing 150 which delimits a first fluid circuit for a first fluid, e.g. charge air.
  • the housing 150 may further receive intake and outtake (not shown) for the first fluid on its open ends.
  • the exemplary first fluid flow direction from intake to outtake is depicted in Fig.1 by F in and F out , respectively

  • the tube 102 is aligned substantially in parallel with respect to the first wall 110 and the second wall 120, and in perpendicular to the manifold 150 and the third wall 130.
  • the tube 102 extends from the manifold 140 to the third wall 130, whereas it is fluidly connected only with the manifold 140.
  • the tube 102 is formed, so as to enable at least one U-turn at the path of the second fluid flowing there through.
  • the manifold 140 is configured to deliver and/or collect the second fluid to the tube 102 through two parallel channels formed therein.
  • the channels in the manifold 150 are formed as a unitary element with e.g. partition, however other means of providing channels for the second fluid are also envisaged.
  • the heat exchanger 100 may include a plurality of tubes 102 to improve the efficiency thereof.
  • the tubes 102 are stacked one on the other in a parallel manner, perpendicularly to the manifold 140, so that the second fluid is distributed as homogenously as possible.

  • the tubes 102 may be initially, i.e. in a pre-operational mode, secured both to the manifold 140 and the third wall 130, yet it may be possible for the tubes 102 to be secured only the manifold 140. As the tubes 102 are directly connected to the housing 102, the tubes 102 may lack flexibility, thereby the tubes may damage and cause leakage of the second fluid.
