Definitions
- the present invention refers to a heat exchanger for an exhaust gas recirculation system (EGR) of an internal combustion engine, and more specifically, a heat exchanger with an integrated by-pass duct.
- EGR exhaust gas recirculation system
- EGR systems exhaust gas recirculation systems in internal combustion engines
- DE-C-914 450 discloses a heat exchanger for the exhaust gases of an internal combustion engine having a cylindrical casing that houses a refrigeration chamber formed by a plurality of refrigeration tubes and a by-pass duct.
- the exchanger is coupled to the exhaust circuit by an end flange having a single opening communicating with both the refrigeration tubes and the by-pass duct.
- a throttle valve controls the by-pass flow.
- the object of the present invention is to provide a heat exchanger including, in a single unit, both the refrigeration chamber for cooling the gases as well as a by-pass duct through which the gases must circulate when their cooling is not necessary, which allows to easily control the gas flow through the refrigeration chamber and the by-pass duct, and thus to limit the engine emissions, and is structurally simple and compact so as to be easily integrated in the engine.
- the heat exchanger is formed by a cylindrical casing and, arranged within the casing, a refrigeration chamber constituted, in a well known manner, of a plurality of tubes (which we shall call refrigerating tubes hereinafter), and a by-pass tube.
- a flange is arranged with a first opening communicating with the refrigerating tubes of the refrigeration chamber and a second opening communicating with the by-pass duct, a separation area existing between said openings.
- the shape of these openings is related to both the desired distribution of the areas intended for the refrigeration chamber and the by-pass duct as well as the shape of the latter.
- the preferred shape for said openings would be that of two circular segments delimited in said circular section by means of a separation strip, the one intended for the refrigeration chamber being larger than a semicircle.
- Said separation area acts as a closing means of the exchanger gas intake side in combination with a valve suitable for opening one of the two openings and simultaneously closing the other, depending on the needs established by the EGR system.
- An additional feature of the invention is that said casing is closed by means of external caps enveloping its edges to aid in assembling the refrigerating tubes and to aid in carrying out the welds. Said coupling flange to the gas intake device would be welded to the corresponding casing cap.
- said by-pass duct is a double-walled duct with an intermediate air chamber.
- part of the exhaust gases from the engine go to the exterior through the exhaust pipe and another part is recirculated.
- the amount to be recirculated is controlled by the EGR valve that, in determined circumstances can even be closed and not recirculate anything, for example in a maximum power situation.
- the recirculated gases mix with the clean air and return to the engine through the intake manifold.
- the recirculated gases may or may not be cooled, depending on the position of the corresponding valve.
- the present invention provides a heat exchanger with the integrated by-pass duct.
- FIGS 1 to 5 show a heat exchanger 1 for exhaust gases according to the present invention formed by a cylindrical casing 2 housing a refrigeration chamber 3 inside constituted of a set of tubes 4, commonly known in the art, and a duct 9 acting as a by-pass duct so that those exhaust gases not to be cooled can pass through it.
- a refrigerating liquid circulates through the casing 2, entering through a duct 5 and exiting through a duct 7.
- the casing 2 is closed with caps 11 and 13 on both sides, serving as fixing means of the tubes 4 and of the by-pass duct 9. These caps envelope the edges of the casing 2, which aids in the assembly process of the tubes 4 and the welding process.
- the heat exchanger 1 for exhaust gases according to the present invention is coupled with the gas intake device (not shown) by means of the flange 15 in which a first opening 21 communicating with the refrigerating tubes 4 and a second opening communicating wiht the by-pass duct 9 are provided.
- a suitable valve (not shown), actuated by the corresponding control means, drive the exhaust gases towards the refrigeration chamber 3 or towards the by-pass duct 9.
- Coupling the heat exchanger to the gas intake manifold of the engine is carried out by using conventional means such as the flange 16, which can be the same as the flange 15 for economic or process reasons, or other known means in the art such as a re-driving cone plus a flange or a re-driving cone and a ring.
- conventional means such as the flange 16, which can be the same as the flange 15 for economic or process reasons, or other known means in the art such as a re-driving cone plus a flange or a re-driving cone and a ring.
- the flange 15 openings 21 and 22 dimensions are closely related to the areas dedicated to the refrigeration chamber 3 and to the by-pass duct 9.
- the presence of a separation area 23 of the openings 21 and 22 can also be seen in the flange 15, in relation with the available space between the refrigerating tubes 4 and the by-pass duct, it is useful as a closing means in combination with said valve.
- the first opening 21 has a circular segment shape of a surface somewhat larger than a semicircle of the casing 2, and the second opening 22 also has a circular segment shape although with rounded vertices.
- the separation area 23 is located between both openings, with its central span delimited by straight lines. Twelve tubes 4 are located facing the first opening 21, and the oval-shaped by-pass duct 9 is located facing the opening 22.
- Figures 6 and 7 show flanges 18 and 19 in which the two openings 21 and 22 have a circular segment shape.
- the by-pass duct 9 has a semicircular shape, and in the second it has an oval shape. It could also have a circular shape and in each case there would be a different degree of use of the space delimited by the opening 22.
- the dimensioning of the openings 21 and 22, the refrigeration area using one or another number and type of refrigerating tubes 4, and the by-pass duct 9 will depend on the functional needs of each case.
- the circular shape will be chosen for the by-pass duct 9 if a better relationship is desired between the passing area and the exchange surface to minimize the heat exchange
- a circular segment shape of Figure 6 will be chosen if the intention is to take maximum advantage of the surface delimited by the opening 22 to minimize the load losses
- the oval shape of Figure 7 will be chosen if the intention is to have an intermediate option between the previous ones.
- the refrigeration chamber 3 will be permanently active since the circulation of the refrigerating liquid through the casing 2 will form part of the general cooling circuit of the engine. Subsequently, the possibility of using double-walled by-pass ducts 9 with an intermediate air chamber is considered in order to ensure that the cooling of the gases circulating through it do not exceed a predetermined value.
