Definitions
- the present invention relates to a heat exchanger module for an exhaust gas recycling system, which can in particular be applied to systems for recycling the exhaust gases from the engine of a vehicle to the intake.
- This exchanger module can be the heating of the intake air as well as the refrigeration of the exhaust gases which are led to the catalytic converter for petrol engines.
- EGR valve exhaust Gas Recycling Cooler
- the actual heat exchanger 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.
- 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 recycling system making it possible to maintain a minimum level of gas emission. pollutants in the exhaust gases, regardless of the engine's operating condition.
- the heat exchange module of this invention is of the heat exchanger type equipped with circuits allowing the flow of exhaust gases, the latter comprising among these means the conduits reserved for the flow of gases with heat exchange with a cooling; its peculiarity lies in the fact that the circuits serving for the flow of the exhaust gases comprise at least one by-pass duct, integrated into 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 a "bypass" makes it possible to avoid cooling of the exhaust gases according to the different operating modes of the engine, for example in the event of a cold start, for which its temperature n is not high and cooling it would be dangerous because of the emission of polluting gases it would generate.
- the exchanger module further comprises circuits for selecting the path of the exhaust gases, thus allowing these selection means to let the gases circulate through the conduits intended for their flow with heat exchange or well by the bypass duct without any real cooling.
- These means for selecting the path of the exhaust gases are preferably equipped with a temperature detector for these gases; it is thus possible to guarantee that, whatever the operating mode of the engine, the gases will be led to the most appropriate conduit, maintaining the emission of polluting gases at a minimum threshold.
- 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 assemble.
- the exhaust gas path selection circuits include a three-way valve; this valve can be placed at the inlet of the exchanger, but it can either located at the exit of the exchanger.
- the means for selecting the path of the exhaust gases comprise a two-position valve which is associated with the bypass pipe mentioned above, which opens or closes the pipe at when the exhaust gases pass.
- This valve makes it possible to direct the exhaust gases to the conduits with heat exchange 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 outlet of said bypass.
- the gases must pass through the tubes of the exchanger, while when the valve leaves the passage through the bypass open, the gases preferably take this path, because they lose less dump; it is possible to install either the valve at the inlet of the bypass.
- valve associated with the bypass is linear drive, since this mode makes it possible to ensure sealing of the assembly more easily; in this case it is possible to choose between a flat seat valve, a needle valve, a gate valve or a piston valve.
- the valve can be either rotatable, and a choice should be made between butterfly valve, ball valve or rotary valve.
- the control of the thermostatic valve is more advantageous; its opening and closing are directly controlled by the temperature of the coolant.
- the thermostatic control removes any external control, which avoids any problem of tightness as well as the need to exercise 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 should preferably be installed on the longitudinal axis of the exchanger.
- This invention also relates to any heat exchanger, in particular for an exhaust gas recycling system, which has circuits for the flow of exhaust gases, including the circuits mentioned above which serve for the flow of gases with heat exchange with a cooling fluid, and which is distinguished by the fact that the circuits serving for the flow of the exhaust gases further comprise at least one bypass, incorporated in the exchanger, suitable for the circulation of the gases exhaust without these being subjected to real cooling.
- the exchanger preferably consists of means for selecting the path of the exhaust gases, thus allowing these selection means to allow the circulation of gases via the pipes intended for their flow. with heat exchange or via the bypass duct without any real cooling.
- FIG. 1 schematically represents a heat exchanger module according to the present invention, in the operating position;
- Figure 2 shows the module of Figure 1 in another operating condition;
- Figure 3 is a sectional view of the heat exchanger;
- FIGS. 4 and 5 are views in longitudinal section of an exchanger according to an application of the present invention, in which a valve with planar seat is mounted, respectively in the closed and open position;
- Figures 6 and 7 are views similar to Figures 4 and 5, for an exchanger provided with a butterfly valve.
- an EGRC module according to the invention comprises a heat exchanger 1, mainly composed of a flange 10 provided with a bundle of tubes 11 further having inside a bypass duct or by- pass 12, of diameter greater than each of the tubes 11 composing the bundle and which is independent of these.
- the 3-way valve 2 At the inlet of the exchanger 1 is the 3-way valve 2, through which the exhaust gases enter by a line indicated by the arrow A, and through which they are led, according to the position of the valve, to the bundle of tubes 11 via the line indicated by arrow B, as shown in figure 1, or to bypass 12 via the line indicated by arrow C, as shown in 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 by- pass 12.
- the exhaust gases from the engine cylinders pass, through the valve shown in FIG. 1, from valve 2 to the tubes 11, through the inlet manifold 13, while in FIG. 2 the gases pass from valve 2 to line 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 module EGRC described also includes circuits making it possible to detect the temperature of the gases leaving the cylinders, as well as means for controlling the valve 2.
- the operation of the module described is simple: during normal engine operation, the valve 2 remains in the position in FIG. 1, and the exhaust gases are cooled in the exchanger, in the traditional way, since they circulate in the tube bundle 11.
- the means to control then change the state of the valve to that of FIG. 2, so 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 gas flow and the cooling fluid is thus reduced, and the gases are not cooled during their passage through the exchanger.
- the flow 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 approximately 500 mm 2 and 1000 mm 2 , this section consisting of a large number of tubes with a hydraulic diameter between 5 mm and 12 mm, inside a flange whose internal diameter is approximately 43 mm to 52 mm.
- the hydraulic diameter of the tubular bypass can be between approximately 10 mm and 40 mm.
- the characteristic values of the temperatures of the gases circulating in a traditional exchanger, when the engine has a normal speed, are 300 ° C at the inlet and 150 ° C at the outlet; in the event of a cold start, the gases entering the exchanger are between 100 and 150 ° C and the exchanger cools them down to 50 ° C.
- the gases leaving the exchanger have practically the same temperature as at the inlet.
- valve 2 either at the inlet of the exchanger, as presented, or at the outlet; in this case, the pressure difference between the inlet and the outlet passes the exhaust gases through the tube bundle or through the bypass 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 in a single module in connection with the exchanger, or to arrange it as an external component.
- an exchanger module will then be defined for different applications of the means for selecting the path of the gases.
- a valve 20 is associated with the bypass duct 12 - in the present case it is a plane seat valve - located on the manifold of exit 14.
- valve 20 is driven (linear drive) via an axis 21, and the outlet manifold 14 is modified as appropriate, the outlet 22 of the gases being effected perpendicular to the axis of the exchanger, to 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 which circulates inside the flange 10 (although its inputs and outputs are not shown in the figures).
- valve 20 opens, as shown in FIG. 5, most of the gases pass through the bypass duct 12, since they meet only an insignificant resistance there and they are not cooled by their passage in the exchanger.
- the other linear drive valves which 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 butterfly valve 20 'has been integrated instead of a plane seat valve 20 as proposed in the previous figures.
- the drive axis 21 'of the rotary valve, and the valve 21 can pass from the closed position of the bypass duct 12 ( Figure 6) to 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 house 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 conduit passing through them, or rotary valves, composed of a plate articulated from a point of its periphery to a hinge pin located on the periphery of the conduit 12 to be closed.
- a rotary drive valve could be installed, such as the butterfly valve 20 ′, by equipping it with a connecting rod-crank system or the like, inside the exchanger, so that the drive mode goes linear.
- the bypass valve can be either pneumatic, electric or thermostatic.
- valve is controlled from the temperature of the gases themselves or from the cooling fluid, so that the bypass duct opens, for example during the cold start of the engine, avoiding thus the exhaust gases do not cool too much.
- This thermostatic drive mode is placed inside the exchanger, in order to avoid the sealing problems associated with the passage of a drive shaft in the flange.
- bypass valve in the outlet manifold (or in the inlet manifold) in a single piece, which would have the consequence of improving the tightness of the assembly.
- the pump body itself will include the connection to the gas circuit.
- bypass inside the exchanger, as well as its final geometry, may vary from one case to another depending on the type of exchanger: for the tube bundle exchanger, the scheduling shown in the figures is entirely suitable since it does not require any significant modification of the exchanger production lines. For a plate heat exchanger, it would be possible to have a duct with a completely different geometry. For all these cases, what is important lies in the fact that the bypass is integrated in the body of the exchanger.
