Definitions

  • the present invention is a flow deflector suitable for a heat exchanger of the type consisting of at least one core made up of tubes forming a bundle arranged inside a shell and at least one baffle.
  • the deflector according to the invention is an easily manufactured part independent from the construction of the bundle of tubes and of the baffle which allows modifying the coolant fluid or liquid flow path with greater freedom than that achieved by combining internal openings in the baffle or baffles.
  • Another object of this invention is the heat exchanger obtained using the deflector for optimising coolant liquid flow path.
  • the configuration of heat exchangers for EGR systems usually consists of a bundle of tubes through which the recirculated gas passes and of a shell housing said bundle of tubes.
  • a coolant fluid circulates between the bundle of tubes and the shell such that the gas circulating through the tubes transfers heat to the coolant liquid.
  • the entry of the coolant liquid occurs at one point of the shell corresponding to an end of the bundle; and the exit at another point of the shell located at the opposite end of the bundle.
  • the entry through a point establishes regions of the volume occupied by the coolant liquid which are stagnation regions. Since the speed is zero or very small in stagnation regions, convection is very low and therefore heat dissipation to other areas does not occur. As a result, the temperature is higher in these areas and worse still the materials which are in contact with these stagnation regions suffer greater thermal stresses. As a result of these high stresses in localised sites of the device, the service life of the materials is unfailingly reduced since they withstand a lower number of thermal fatigue cycles.
  • a decrease in thermal stress level implies an increase in the number of thermal fatigue cycles withstood by the device without it malfunctioning. This increase in thermal fatigue cycles withstood by the device follows the behaviour similar to that of an exponential function. The decrease in thermal stresses and therefore in thermal fatigue, and the subsequent increase in the exchanger durability is achieved by means of a homogenous temperature distribution especially in the hotter areas.
  • flow deflection means are incorporated, for example, for moving the coolant liquid in a zigzag manner and increasing its speed and thus improving heat convection, as shown by e.g. JP2008196319 A .
  • This flow deflection is achieved by means of the shape of the inner openings of the baffles responsible for securing the tubes of the bundle of tubes assuring a specific separation between said tubes.
  • the more common configuration of these baffles is that of a perimetric ring-shaped die-cut plate according to the configuration of the perimeter of the bundle of tubes; and, having elongations towards the inside of the comb-shaped perimetric ring.
  • These comb-shaped elongations are intended for being housed between the tubes of the bundle and prevent the passage of the coolant liquid through them.
  • baffles If the elongations are short the opening left by these elongations inside the bundle are larger.
  • the flow passing through these baffles is forced to follow the path imposed by the position and size of the openings by combining several baffles with different internal openings, the openings defining the ends of these elongations. For example, placement on alternate sides of the internal openings will give rise to a zigzag path.
  • Incorporating the baffles to the bundle of tubes allows assuring the distances between tubes. Manufacturing is carried out by die-cutting sheet metal which is welded to this bundle. If the comb-shaped elongations of the baffles are excessively styled the manufacturing complexity increases given that dimensional stability and the tolerances demanded by mass production are more difficult to achieve.
  • baffles are arranged essentially perpendicular to the tubes of the bundle of tubes therefore the deflection is not always optimum and the pressure losses are higher than if oblique flow deflections could occur.
  • the present invention uses a part intended for being secured, preferably by clipping, in an already existing baffle the configuration of which is not limited by manufacturing demands, by geometry limitations of a part obtained by die-cutting sheet metal, and by limitations of baffle welding.
  • the present invention solves the problems identified above by using a part which can be manufactured in plastic, resin or other materials, intended for being installed, preferably by clipping, on a baffle.
  • the baffle can be of very simple design since it is no longer required to be responsible for coolant fluid or liquid flow deflection.
  • the part according to the invention is a flow deflector suitable for a heat exchanger of the type consisting of at least one core made up of tubes forming a bundle arranged inside a shell and at least one baffle, such that said deflector comprises:
  • the part of the deflector which intervenes by modifying the coolant fluid flow path is the deflecting extensions.
  • the position thereof depends on the particular embodiment. Two particular examples will be shown below, although there can be more; a first example in which the deflecting extensions are located at the end of the fixing elongations giving continuity to such elongations; and a second example in which these deflecting extensions are located on one side of the main plane P linked to the main body by means of a resistant bridge. This second embodiment gives no reason for flow deflection to occur in the position of the baffle.
  • these deflecting extensions can adopt degrees of inclination or curvature which would not be possible, or would be very complicated, to impose on one part of the baffle.
  • Figure 1 shows a heat exchanger according to the state of the art formed by a core (2) and a shell (3) where coolant liquid flow is directed by means of baffles (2.2) for the purpose of increasing heat convection and therefore exchanger efficiency.
  • baffles 2.2
  • baffles (2.2) are resistant elements which must be welded to the bundle (2) of tubes (2.1).
  • the manufacturing and welding requirements do not have to be compatible with the deflection surface requirements and therefore do not allow defining an optimum flow configuration.
  • Figure 2 shows a baffle (2.2) incorporating comb-shaped elongations intended for being housed between the tubes (2.1) of the bundle (2) covering the space defining the separation between the tubes.
  • the ends of the comb-shaped elongations are the edges of the internal window through which the passage of the coolant liquid is allowed.
  • the passage and path of the coolant liquid can be modified by alternating the areas and positions of these windows but it has the drawbacks already mentioned in the state of the art.
  • the present invention uses a part, the deflector (1), intended for being incorporated in a baffle (2.2) where this baffle (2.2) is very simple to manufacture since it does not require thin and long elongations for modifying inner coolant liquid flow.
  • Figures 4a, 4b, 4c and 4d are the elevational, profile view of this first example whereas Figures 4c and 4d are two perspective views which allow observing the same part (1) from almost opposite positions for offering visual access to all the details.
  • the deflector (1) according to this first embodiment is seen before and after being inserted in its operating position by means of Figures 3a and 3b .
  • the deflector (1) is located on the baffle (2.2) such that in this view it is possible to see the protruding edge of the baffle (2.2) on which the deflector (1) will be located.
  • the baffle (2.2) has a configuration with short internal elongations such that it does not limit the flow of coolant liquid through it.
  • the deflector (1) comprises a main body (1.1) extending along the X-X direction.
  • the main body (1.1) is intended to rest on the baffle (2.2) and the elongations (1.2, 1.3) which allow fixing on the baffle (2.2) protrude from the main body.
  • Figure 4b shows the main plane P, which in this embodiment coincides with the plane of symmetry, leaving a group of fixing elongations (1.2) on one side and the remaining fixing elongations (1.3) on the other side.
  • This same view 4b as well as the perspective view 4d allow observing the spacing of the fixing elongations (1.2, 1.3) with respect to plane P and therefore the separation between both groups of elongations. Said separation gives rise to a housing (H) for the sector of baffle (2.2) resulting in a fixing mode between both elements (1, 2.2).
  • each of the fixing elongations (1.2, 1.3) has a deflecting extension (1.2.2, 1.3.2) configured as a continuation of the fixing elongation (1.2, 1.3).
  • the deflecting extension (1.2.2, 1.3.2) there is a staggering arranged on the inner side orientated towards the main plane P. This staggering is intended for resting on the end of the elongations of the baffle (2.2) assuring their retention and preventing them from coming out.
  • the ends of the deflecting extensions (1.2.2, 1.3.2) of this embodiment are bevelled on the inner side orientated towards the main plane P.
  • This bevelling allows the insertion on the baffle (2.2) during assembly facilitating the opening by means of bending the set formed by the deflecting extension (1.2.2, 1.3.2) and the fixing elongation (1.2, 1.3).
  • the insertion is completed when the sector of baffle (2.2) which is housed in the housing (H) overcomes the staggerings (1.2.1, 1.3.1) allowing the shape recovery of the set of fixing elongations (1.2, 1.3) together with the deflecting extensions (1.2.2, 1.3.2).
  • a material with elastic behaviour in the range of deformations imposed by the thickness of the baffle (2.2) and the different dimensions of the deflector (1) intervening in the insertion has been selected for allowing an easy shape recovery.
  • a second embodiment is shown in detail in Figures 5 and 6 .
  • the main body (1) extends according to the X-X direction and comprises a channel (1.6) which also extends in the X-X direction intended for housing the outer edge of the baffle (2.2) when the deflector (1) is installed on the baffle (2.2).
  • FIG. 5 shows a perspective view of the main plane P passing in the X-X direction and leaving the fixing elongations (1.2, 1.3) on both sides.
  • the fixing elongations (1.2, 1.3) are shown in groups of three, and in each group of three, two fixing elongations (1.3) are on one side and the third fixing elongation (1.2) is on the opposite side of the main plane P.
  • This third fixing elongation (1.2) is arranged between the other two fixing elongations (1.3) following the X-X direction. Only three fixing elongations (1.2, 1.3) would thus be sufficient for assuring a fixing preventing movements in directions perpendicular to the X-X direction and even rotational movements.
  • the bevelling which facilitates the insertion of the deflector (1) in the baffle (2.2) is in the fixing elongations (1.2, 1.3).
  • the space between tubes (2.1) is narrower than the space between the bundle (2) of tubes (2.1) and the shell (3).
  • the lower flow resistance in this second space means that the entire flow tends to circulate outside the bundle of tubes (2.1).
  • the presence of reinforcement (1.5.1) covering the space between the bundle (2) of tubes (2.1) and the shell (3) has the effect of forcing the flow to circulate between the tubes (2.1) increasing the cooling efficiency.
  • the deflecting extensions (1.5) have a width slightly less than the space between tubes (2.1) giving rise to a clearance. Although the deflecting extensions (1.5) divert the flow reaching them, the existence of a clearance allows a small part of the flow to pass between the deflecting extension (1.5) and the tube (2.1) preventing stagnation regions which would give rise to points which could easily reach boiling temperature behind the deflecting extension (1.5).
  • the deflecting extensions (1.5) elongate by way of ribs until reaching the main body (1.1).
  • Figure 8 shows the bundle (2) of tubes (2.1) after having removed the shell (3) with the flow deflector (1) before being inserted on the baffle (2.2).
  • the fixing elongations (1.2, 1.3) enter the spaces between tubes (2.1) being located on both sides of the baffle (2.2) by means of the downwards movement thereof (moving downward according to the orientation shown in the figure).
  • the deflecting extensions also enter the spaces between the tubes (2.1) reaching the final position which is shown in Figure 8 .
  • This figure shows two baffles (2.2); nevertheless, flow deflection does not occur in the position of the baffles (2.2) but in the position where the deflecting extensions (1.5) are located which, as a result of the resistant bridge (1.4), are away from the baffle (2.2).
  • Figure 9 shows a section of the heat exchanger according to a plane which is orientated in the direction of the tubes (2.1) of the bundle (2).
  • the tubes (2.1) are essentially planar. This section allows observing how the deflecting extensions (1.5) reach approximately the width of one of the two tubes (2.1) giving rise to the total height of the bundle (2) of tubes (2.1). The flow will be diverted so that it will be redirected to the lower tubes (2.1) (also following the orientation shown in the drawing). In this embodiment, the deflecting surfaces are inclined so that the diverted flow has an axial component according to the main axis of the bundle (2) of tubes (2.1). Nevertheless, these extensions can adopt other more complex configurations such as curves imposing a specific configuration to the stream lines.
