Definitions

  • the present invention relates to a heat exchanger module for an exhaust gas recirculation system, which can in particular be applied to the exhaust gas recirculation systems of the engine of a vehicle to the intake.
  • Other applications of this exchanger module may be the heating of the intake air and the refrigeration of the exhaust gases which are led to the catalytic converter for the gasoline engines.
  • the exhaust gases are cooled in a heat exchanger (EGRC or "Exhaust Gas Recycling Cooler" mounted on the loop of the EGR system, so as to improve the efficiency of the system.
  • EGRC Exhaust Gas Recycling Cooler
  • EGR valve which controls the passage of the exhaust gas in the exchanger.
  • the heat exchanger itself can have different configurations: for example, it can consist of a tubular flange inside which is arranged a series of parallel tubes in which the gases circulate, the refrigerant spreading in the flange, outside the tubes; in another application, the exchanger is composed of a series of parallel panels which constitute the exchange surfaces heat, so that the exhaust gases and the refrigerant circulate between two panels in alternating layers (see for example DE-A-914 450 ).
  • the current EGR systems which are cooled have a disadvantage because the exhaust gases circulate via the exchanger whatever the mode of operation of the engine from the moment the EGR valve opens: the gases are cooled as long as the engine is operating at steady state and its temperature is high, such as during a cold start, when the temperature of the gases is much lower.
  • the object of the present invention is to provide a solution to the drawbacks mentioned above by developing a heat exchanger module designed specifically for an exhaust gas recirculation system for maintaining a minimum level of gas emission. pollutants in the exhaust, irrespective of the engine operating condition.
  • the heat exchange module of this invention is of the heat exchanger type equipped with circuits allowing the flow of the exhaust gases, the latter comprising among these means the ducts reserved for the flow of gases with heat exchange with a fluid of cooling; its particularity lies in the fact that the circuits used for the flow of the exhaust gases comprise at least one bypass duct, integrated in the exchanger, which is suitable for the circulation of the exhaust gases without these being subjected to a real cooling.
  • bypass duct which can simply be called “bypass" makes it possible to avoid the cooling of the exhaust gases according to the different modes of operation of the engine, for example in the case of a cold start, for which its temperature does not vary. is not high and its cooling would be dangerous because of the emission of gaseous pollutants that it would generate.
  • the exchanger module further comprises circuits for selecting the path of the exhaust gas, thus enabling these selection means to let the gases circulate through the ducts intended for their flow with heat exchange or well by the bypass duct without there being any real cooling.
  • These means for selecting the path of the exhaust gases are preferably equipped with a temperature detector of these gases; it is thus possible to ensure that, whatever the mode of operation of the engine, the gases will be led to the most appropriate conduit, maintaining a minimum threshold emission of gaseous pollutants.
  • the means for selecting the path of the exhaust gases are incorporated at least in part in the heat exchanger module. This feature allows the device to be compact and simple to mount.
  • the exhaust path selection circuits comprise a three-way valve; this valve can be placed at the entrance of the exchanger, but it can indifferently be at the exit of the exchanger.
  • the exhaust path selection means comprise a two-position valve which is associated with the aforementioned bypass conduit, which opens or closes the conduit at moment of the passage of the exhaust gases.
  • This valve allows to direct the exhaust gases to the heat exchange ducts or to the bypass, depending on the nature of these gases, in a simple manner and without complicating the structure of the exchanger.
  • this valve is mounted at the output of said bypass.
  • the gases must necessarily pass through the tubes of the exchanger, whereas when the valve leaves the passage through the bypass open, the gases preferably take this path, because they lose less charge; it is possible to install indifferently the valve at the input of the bypass.
  • the valve associated with the bypass is linearly driven, since this mode makes it possible to seal the assembly more easily; in this case, it is possible to choose between a plane seat valve, a needle valve, a gate valve or a piston valve.
  • the valve may be rotatable, and a choice must be made between a butterfly valve, ball valve or rotary valve.
  • thermostatic valve is more advantageous; its opening and closing are directly controlled by the temperature of the refrigerating liquid.
  • the thermostatic control eliminates any external control, which makes it possible to avoid any problem of tightness as well as the need to exert an external control.
  • the exchanger has the general structure of an exchanger equipped with a bundle of parallel tubes in which the exhaust gases circulate, the bypass being composed of a single tube, section roughly equivalent to the total section of this bundle of tubes; this tube will preferably be installed on the longitudinal axis of the exchanger.
  • This invention also relates to any heat exchanger, in particular for an exhaust gas recirculation system, which includes exhaust gas flow circuits, including the aforementioned circuits which serve for the flow of gases with heat exchange with a cooling fluid, and which is distinguished by the fact that the circuits used for exhaust gas flow further comprise at least one bypass, incorporated in the exchanger, suitable for the circulation of the gases of exhaust without these undergoing a real cooling.
  • the exchanger preferably consists of means for selecting the path of the exhaust gas, thus enabling these selection means to allow the flow of gas via the ducts intended for their flow. with heat exchange or via the bypass duct without any real cooling.
  • an EGRC module comprises a heat exchanger 1, composed mainly of a flange 10 provided with a bundle of tubes 11 further having inside a bypass duct or by- pass 12, of greater diameter than each of the tubes 11 constituting the beam and which is independent of them.
  • valve 2 At the inlet of the exchanger 1 is the valve 2, three-way, through which enter the exhaust gas by a line indicated by the arrow A, and through which they are driven, depending on the position of the valve, to the bundle of tubes 11 via the line indicated by the arrow B, as shown in figure 1 , or to the bypass 12 via the line indicated by the arrow C, as shown in FIG. figure 2 .
  • the tubes 11 converge at the ends of the flange in two annular collectors, an inlet manifold 13 and an outlet manifold 14, which are arranged around the bypass 12. exhaust from the engine cylinders pass through the valve shown in figure 1 , from the valve 2 to the tubes 11, through the inlet manifold 13, while figure 2 the gases pass from the valve 2 to the conduit 12.
  • a cooling fluid circulates inside the flange 10, but outside the tubes 11 and the bypass 12, between the fluid inlet 15 and a fluid outlet 16.
  • the EGRC module described also includes circuits for detecting the temperature of the gases at the cylinder outlet, as well as means for controlling the valve 2.
  • the means of control change the state of the valve to that of the figure 2 in such a way that most of the exhaust gases pass through the exchanger 1 via the bypass 12: because of the relatively large diameter of this duct, the heat exchange between the flow rate of the gases and the cooling fluid is thus reduced, and the gases are not cooled during their passage through the exchanger.
  • the flow rate of gas recycled by the exchanger is usually between 5 g / s and 15 g / s, for a flow section with a heat exchange of between about 500 mm 2 and 1000 mm 2 , this section consisting of a large number of tubes with a hydraulic diameter of between 5 mm and 12 mm, inside a flange whose inner diameter is about 43 mm to 52 mm.
  • the hydraulic diameter of the tubular by-pass may be between 10 mm and 40 mm approximately.
  • the characteristic values of the temperatures of the gases flowing in a conventional exchanger, when the engine is at a normal speed, are 300 ° C at the inlet and 150 ° C at the outlet; in case of cold start, the gases at the inlet of the exchanger are between 100 and 150 ° C and the exchanger cools them to 50 ° C.
  • the gases leaving the exchanger have almost the same temperature as at the inlet.
  • valve 2 it is possible to install the valve 2 either at the inlet of the exchanger, as shown, or at the outlet; in this case, the pressure difference between the inlet and the outlet causes the exhaust gases to pass through the tube bundle or by-pass depending on the location of the valve.
  • the modeling technique applied to the valve can take any form suitable for the design of the exchanger and its bypass; he is possible to integrate it into a single module in connection with the exchanger, or to have it as an external component.
  • an exchanger module will then be defined for different applications of the gas path selection means.
  • a valve 20 is associated with the bypass duct 12 - in this case it is a plane seat valve - located on the outlet manifold 14.
  • the drive of the valve 20 (linear drive) is effected via an axis 21, and the outlet manifold 14 is suitably modified, the outlet 22 of the gases being effected perpendicular to the axis of the exchanger, for allow to house the valve 20 and its drive devices.
  • bypass duct 12 remains in the closed position, since the gases must necessarily pass through the tubes 11, as shown by the arrows; they are then cooled by the coolant circulating inside the flange 10 (although its inputs and outputs are not shown in the figures).
  • valve 20 opens, as shown in figure 5 most of the gases pass through the bypass duct 12, since they encounter only insignificant resistance and they are not cooled by their passage through the exchanger.
  • linear drive valves that could replace the butterfly valve 20 are needle valves, gate valves of different sections or piston valves.
  • FIGS. 6 and 7 show a variant of the application of the exchanger, in which a throttle valve 20 'has been incorporated instead of a plane seat valve 20 as proposed in the preceding figures.
  • the drive shaft 21 'of the rotary valve, and the valve 21 can pass from the closed position of the bypass duct 12 ( figure 6 ) at an open position of the duct 12 ( figure 7 ).
  • the modification of the outlet manifold 14 is limited to its elongation which allows it to accommodate the valve 20 '.
  • the other rotary drive valves which may also be suitable for the application described may be two-way ball valves, which are provided with a duct passing therethrough, or rotary valves, composed of a plate articulated from a point of contact. its periphery to an axis of articulation located at the periphery of the duct 12 to be closed.
  • the bypass duct valve can be either pneumatically, electrically or thermostatically driven.
  • the control of the valve is carried out from the temperature of the gases themselves or the cooling fluid, so that the bypass duct opens, for example during the cold start of the engine, avoiding as well as the exhaust gases do not cool too much.
  • This thermostatic drive mode is placed inside the exchanger, in order to avoid sealing problems related to the passage of a drive shaft in the flange.
