Definitions

  • the invention deals with heat exchangers, in particular header covers of heat exchangers according to the preamble of claim 1.
  • JP 2006 118425 discloses such a header cover.
  • the invention finds an advantageous application in heat exchanger systems for automotive vehicles, more particularly in cooling radiators for coolant fluid with high-speed flow, for example around 15000 l/h.
  • Existing heat exchangers for automotive vehicles comprise a heat exchanger core that is formed using a plurality of tubes laid out in parallel on one or several rows. These tubes allow a coolant fluid, such as e.g. water added with glycol in the case of engine cooling radiators, to flow or circulate across the heat exchanger. Coolant fluid, by cooling elements of the engine, warms up and must be cooled in its turn. It is the role of the radiator to provide this function. For this purpose, water to be cooled is put in circulation in the tubes of the radiator and cools by heat exchange with fresh air, heat exchange being realized via elements of heat transfer laid out between the tubes.
  • a coolant fluid such as e.g. water added with glycol in the case of engine cooling radiators
  • the elements of heat transfer are parallel fins crossed, in holes performed in the fins, by the tubes of circulation of fluid.
  • the whole is maintained altogether mechanically by means of a tool introduced inside the tubes so as to deform the walls of the tubes and to apply them to force against the holes bored in the fins.
  • fins placed between the tubes Another technology of assembly is the brazing of the tubes and elements of heat transfer called fins placed between the tubes.
  • these fins are shaped in the form of an undulated surface, the fins being brazed on the tubes at the tops of the undulations.
  • the invention applies as well to heat exchanger cores with mechanical assembly as with heat exchanger cores with assembly by brazing.
  • the coolant is introduced into the tubes of circulation of the heat exchanger core via a distribution header placed at the entry of the beam of tubes and provided with a pipe or nozzle of arrival of the fluid.
  • a header of the same type is installed on the outlet side of the exchanger to collect the fluid after circulation in the tubes and evacuate it through an outlet piping nozzle.
  • the header also called manifold or "radiator tank” or “water tank”, consists of two parts, namely a header cover for collecting of fluid, and a collecting element called header plate.
  • the header plate is an element in contact with the heat exchanger core.
  • the header plate carries openings or slits intended to receive the end of the tubes emerging in the distribution header.
  • a joint or gasket ensuring the sealing between the header and the heat exchanger core is laid out on the heater plate.
  • the ends of the tubes exceed inside the radiator tank, for example around 2 to approximately 3 mm for the heat exchanger core with mechanical assembly. It is slightly weaker for the brazed heat exchanger core.
  • the header cover forms a lid for the collecting element and defines a volume of fluid in circulation at the inlet as well as at the outlet side of the heat exchanger.
  • header covers present a U-shaped open vault, the header plate closing the U, for instance by crimping.
  • inlet nozzle or exit of the fluid emerges in the header cover through a wall or side of the vault.
  • the invention concerns a header cover of both input or output of fluid.
  • the fluid, inside the header cover generally reaches values which, at least locally, can lead to very high peaks, for example more than 8 m/s. It results that the flow in the header cover, such as it is carried out today, seriously affects the resistance of the exchanger.
  • the tubes whose ends stick out in the distribution header, in a central zone located in the vicinity of the outlet of the nozzle, present degradations in the forms of holes appearing by erosion of the wall of the tubes approximately 10 mm beneath the header plate, which generates a risk of leakage in the heat exchanger.
  • the formation of these holes is due to a flow peak of the fluid towards the interior of the tubes related to the reflection of the flow on the opposite wall of the vault.
  • Another type of degradation due to the circulation of fluid at high speeds may involve an erosion of the extremities of the tubes sticking out inside the header.
  • the flow becomes swirling with strong speed components parallel to the axis of the vault.
  • the degradations observed on the tubes in these zones concern especially the erosion and the deformation of the ends of the tubes, these two phenomena being likely to create an opening in the seal and thus to cause a leakage in the header.
  • An existing solution for these problems implies using two opposed deflectors, whose edges lay out on an axis parallel to the axis of circulation of the fluid in the heat exchanger core.
  • a drawback of such a solution is that the size of these deflectors may create significant pressure drops when the coolant runs at high speed in the header.
  • Another drawback is that the coolant is only split between two directions, namely left and right when hitting the deflector, which may cause an incorrect repartition of the coolant among the tubes of the heat exchanger core.
  • Another drawback of such a solution is that it may not be suitable for deflecting fluid toward the nozzle in the outlet of the heat exchanger.
  • the invention proposes a header cover, in particular for heat exchangers of automotive vehicles, comprising a vault and a fluid input and/or output nozzle opening out into the header cover through a side of said vault.
  • the header cover is configured for conveying a fluid to or from a plurality of tubes of circulation of a heat exchanger core.
  • the vault of the header cover is configured to open out on the heat exchanger core.
  • the header cover comprises a plurality of deflectors superimposed on one side of the vault, opposite to the opening of the nozzle, in an axis defining an angle, especially a right-angle, with a plane defined by an opening of the vault on the heat exchanger core.
  • an angle we mean in a direction which is not parallel to the plane defined by the opening of the vault on the heat exchanger core.
  • the vault of the header cover according to the invention further comprises a rounded hump, higher than the apex of the vault, said rounded hump comprising two opposite sides and defining a volume at the location of the nozzle, wherein the deflectors of the plurality of deflectors spread between said opposite sides of the rounded hump. This allows creating a space for the deflectors in the header cover further optimizing the fluid flow.
  • the plurality of deflectors comprises ribs or blades. Ribs and blades increase the spreading of the fluid among the tubes of the heat exchanger core.
  • the deflectors of the plurality of deflectors are laid out in parallel. This makes the distribution of fluid uniform between the deflectors.
  • the deflectors of the plurality of deflectors are bent down, relatively to the plane defined by the opening of the vault on the heat exchanger core, toward the heat exchanger core.
  • the deflectors of the plurality of deflectors are bent up, relatively to the plane defined by the opening of the vault on the heat exchanger core, toward the nozzle.
  • the deflectors of the plurality of deflectors are straight, in a plane parallel to the plane defined by the opening of the vault on the heat exchanger core. This allows in particular the header cover to be used both as an input and an output header cover.
  • the vault has a half-pipe shape. Such a shape helps driving the flow of fluid through the header cover.
  • the nozzle is located in the middle of a side of the vault along its longitudinal axis. This allows a uniform distribution of the fluid between tubes located on both sides of the nozzle. Alternatively, it can be located close to a longitudinal end of the header cover.
  • the invention also concerns a heat exchanger.
  • the heat exchanger comprises a header cover as described here above.
  • the heat exchanger further comprises a header plate configured for receiving a heat exchanger core and a header cover as described here above.
  • the header plate allows, on one side, receiving the tubes of the heat exchanger core and, on the other side, receiving the header cover.
  • the header plate comprises slits for receiving the tubes of circulation of fluid, respectively from and to the header cover, of the heat exchanger core.
  • the slits allow the tubes to be strongly inserted in the header plate and thereafter fixed in regard to the header cover.
  • the header plate further comprises a groove, configured for receiving the header cover, and a gasket at the junction between the groove and the header cover for making the junction waterproof.
  • the groove allows the header cover to be well positioned on the header plate.
  • the gasket renders the junction between the groove of the header plate and the header cover waterproof.
  • the heat exchanger comprises a first header cover as described here above and a second header cover as described here above.
  • the first header cover is configured for acting as an input header cover for inputting a fluid into the heat exchanger.
  • the deflectors of the plurality of deflectors of the first header cover are oriented toward the heat exchanger core.

  • Figures 1 to 8 show a header cover 10, comprising a vault 11 and a fluid input and/or output nozzle 13 opening out into the header cover 10 through a side 12 of said vault 11.
  • the header cover 10 is configured for conveying a fluid 5 to or from a plurality of tubes 32 of circulation of a heat exchanger core 30.

  • the vault 11 has a half-pipe shape.
