Definitions

  • the invention relates to a flat tube.
  • the invention relates to a flat tube for a heat exchanger.
  • heat exchangers conventionally comprise a core bundle of tubes and two collector tubes such as manifolds through which the ends of the tubes of the core bundle of tubes pass and which are capped by fluid distribution box covers. There may be inserts placed between the tubes of said core in order to improve the exchange of heat.
  • Heat exchanger tubes may be subjected to numerous stresses such as high-speed impact with an object (for example a stone chipping) coming from the external environment. Heat exchanger tubes are therefore subjected to external stresses.
  • the tubes are also stressed from the inside by the flow of the fluid. Specifically, during operation, the tubes are subjected to thermal, pressure, expansion stresses.
  • One known solution is to allow the tube to withstand such an impact in order to avoid any leak of fluid, or to withstand the internal stresses, by locally increasing the thickness of the wall of the tube in the case of an extruded tube.
  • the tube cannot be reinforced by simply increasing the thickness of material as it can in the case of an extruded tube.
  • a prior art flat tube according to the preamble of claim 1 is disclosed in DE102008007597 .
  • the object of the invention is, among others, a flat tube for a heat exchanger according to claim 1.
  • the longitudinal edges are inclined with respect to the first section towards either of the side walls portions.
  • the longitudinal edges are on the same level with respect to the surface of the second wall.
  • the seam comprises a third section extending along the third portion of the seam arranged in series between the first and the second portion of the seam and along the longitudinal axis of the flat tube.
  • the third section gradually inclines from the first section towards the second section.
  • the flat tube comprises a first open end and second open end, wherein the second section is located in the vicinity of at least one of the open ends.
  • At least one second section is located between at least two first sections along the longitudinal axis of the flat tube.
  • the incision is formed substantially in parallel with respect to the surface of the second wall.
  • Another object of the invention is a heat exchanger comprising at least one flat tube.
  • the heat exchanger further comprises: a first manifold, a second manifold, wherein the flat tube is configured to provide a fluidal communication between the manifolds.
  • the heat exchanger further comprises at least one secondary tube wherein the secondary tube comprises only the first section extending between the open ends thereof.
  • the manifolds comprise slots for receiving at least the flat tubes, wherein the second section extends through and beyond the outline of the slots on both of its sides.
  • the heat exchanger comprises at least one fin interlaced between any of the flat tubes or secondary tubes, wherein the second section extends from the slot at least to the outline delimited by the terminal end of the fin.
  • the flat tube allows to reduce the mechanical stress at desired location of the tube.
  • the second section significantly increases the flexibility of the flat tube which allows it to withstand high pressure and temperature.
  • the heat exchangers comprising such flat tube are advantageous with respect to prior art solution, because its flat tubes are easy to manufacture, they do not require using additional components, and thus they are also inexpensive to produce.
  • the invention relates to a flat tube 1.
  • the flat tube 1 may be adapted for operation in a heat exchanger 100 for a flow of a fluid therein.
  • the heat exchanger 100 may be a radiator and the fluid circulating therein may be a coolant.
  • Other heat exchangers in which the flat tube 1 may be applied are also envisaged.
  • FIGS. 1 and 2 show the prior art flat tube 1.
  • the flat tube 1 may be formed by bending a sheet metal strip 2 along its length.
  • Term “metal strip” refers to a metallic sheet comprising two longer sides which may be further referred to as “longitudinal edges” and two substantially shorter sides, substantially parallel to said longer sides.
  • the metal strip may be made of, for example, aluminum, yet other materials are also envisaged.
  • the metal strip 2 may be bent along its longitudinal edges 2A, 2B to form a closed profile.
  • the flat tube 1 may extend along its longitudinal axis. In other words, the flat tube 1 may comprise its axis of elongation.
  • the flat tube 1 may further comprise a first wall 3 and a second wall 4 parallel to the first wall 3, wherein said walls 3, 4 are formed after bending the metal strip 2. Said walls 3, 4 may be substantially flat. In order to form a closed profile, the flat tube 1 may further comprise two complementary side wall portions 6 joining said first and second walls 3, 4 together.
  • the first fall 3 may comprise a seam 5.
  • the seam 5 may extend along the longitudinal axis of the flat tube 1 so that juxtaposed longitudinal edges 2A, 2B of the metal strip 2 join together in parallel manner towards the second wall 4 to form the closed profile of the tube 1.
  • the longitudinal edges 2A, 2B are bent inwardly at substantially right angle, so that they protrude towards the second wall 4 and they are in contact with each other substantially from the first wall 3 to the second wall 4.
  • the terminal ends of the longitudinal edges 2A, 2B are fixed for example, by brazing to the second wall 4.
  • the metal strip 2 may also be brazed along the portion extending between the first wall 3 and the second wall 4, wherein the longitudinal edges 2A and 2B are substantially parallel and in contact with each other. Consequently, the seam 5 may comprise a first section 5A fixed to the second wall 4 and extending along the first portion of the seam 5 along the longitudinal axis of the flat tube 1.
  • the seam 5 may comprise the first section 5A fixed to the second wall 4 and extending along the first portion of the seam 5 along the longitudinal axis of the flat tube 1 allows the coolant to circulate within the heat exchanger 100 while providing efficient heat exchange between the coolant and different medium (e.g. air).
  • different medium e.g. air
  • known tubes tend to crack which may cause coolant leaks, especially in the vicinity of the terminal ends thereof. The cracks may be caused by lack of flexibility of the flat tube 1. Lack of flexibility combined with high pressure and temperature of the coolant may significantly reduce the robustness of the flat tube 1.
  • Figures 3-10 show an exemplary solutions which would allow to avoid or mitigate negative aspects of prior art flat tubes 1.
  • the seam 5 may comprise a second section 5B.
  • the second section 5B may increase the flexibility of the flat tube 1 where needed.
  • the second section 5B may extend along the second portion of the seam 5 arranged in series with respect to the first portion of the seam 5 and along the longitudinal axis of the flat tube 1.
  • Term "arranged in series” means that the second section 5B is located directly and subsequently to the first section, or that second section 5B is located in the vicinity of the first section 5A whereas there may be another section between them which allows a transition from the first section 5A to the second section 5B.
  • the second section 5B may be separated from the second wall 4. More precisely, the second section 5B protrudes from the first wall 3 substantially towards the second wall, yet it does contact the second wall 4. This allows the flat tube 1 to be more flexible during its operational mode. It allows to compensate differences between the pressure and the temperature, so that the flat tube 1 keeps its structural integrity and fluid tightness at all times.
  • An exemplary ways of providing the flat tube 1 comprising the second section 5B are discussed in further paragraphs.
  • the first way of providing the flat tube 1 comprising the second section 5B is, for example, punching the terminal end of the flat tube 1 with the special tool.
  • the goal is to separate the first section 5A from the second wall 4, so that these elements form a gap.
  • the first wall 3, the second wall 4 and the side wall portions 6 may remain intact.
  • the second section 5B may thus comprise the longitudinal edges 2A, 2B being inclined with respect to the first section 5A towards either of the side walls portions 6.
  • the inclination may vary depending on the shape of the tool which formed the second section 5B and it makes no significant difference between the flow of the coolant through the first section 5A of the flat tube 1 and the second section 5B of the flat tube 1.
  • the longitudinal edges 2A, 2B forming the second section 5B may be on the same level with respect to the surface of the second wall 4.
  • the second section 5B may comprise two portions, both being at the same distance from the second wall 4.
  • the flat tube 1 may also comprise at least one dimple (not shown).
  • the dimples are not shown for the sake of clarity of the drawings.
