Definitions
- the present invention relates to a heat exchanger for gas, in particular for a exhaust gas recirculation from an engine.
- the gases exhaust Before being mixed with the intake air, the gases exhaust can be cooled in an exchanger heat (EGRC or "Exhaust Gas Recycling Cooler”) installed in the EGR system loop to improve system performance.
- EGRC Exhaust Gas Recycling Cooler
- the system loop also has a valve (EGR valve) which regulates the passage of gases exhaust through this one.
- EGR valve a valve which regulates the passage of gases exhaust through this one.
- the actual heat exchanger may have distinct configurations: it can, for example, consist of a tubular carcass inside which is arranged a network of parallel tubes for the passage of gases, the refrigerant circulating in the carcass, outside the tubes; in an other embodiment, the exchanger comprises a series of plates parallel constituting the exchange surfaces of heat, so that the exhaust gases and the refrigerant circulate between two plates, in layers alternating.
- Said heat exchangers include at least one tank and an independent flange or fitting connecting it to the gas recirculation line exhaust.
- said exchangers include a inlet tank and outlet tank, said reservoirs being respectively coupled to the conduits inlet and outlet of the recirculation line by respective independent fittings.
- the diameter of the inlet duct is generally less than the diameter of the carcass and that of the network of exchanger tubes; to ensure the routing of exhaust gases from the duct input to the tube network, so there is between them said inlet tank whose section transverse increases gradually.
- the diameter of the outlet pipe is less than the diameter of the carcass and that of the network of exchanger tubes; analogously, to ensure the delivery of exhaust gases now cooled from the tube network to the duct outlet, there is therefore between them said reservoir of outlet whose cross section decreases gradually.
- fittings There are various types of fittings and we know by example of fittings with a configuration concave or outwardly shaped as well as fittings with a convex configuration or inwardly shaped.
- the tanks are also generally manufactured by stamping, while the fittings are usually manufactured by machining, but also possibly by stamping, sintering, hydroforming or microfusion.
- the gas heat exchanger of this invention aims to remedy the drawbacks of fittings and tanks known in the art, in offering a series of advantages which will be described in the following.
- the gas heat exchanger object of this invention is characterized in that the tank and the fitting are integrated in one piece manufactured by stamping.
- the production process consists of a process classic stamping in several stages, starting from a rolled material on reel using presses commercial.
- Stamping allows you to define complex shapes, especially parabolic, hyperbolic, etc. of the connection surface of the tank and the fitting, this which thus improves the passage of the gas flow.
- the exchanger includes a part incorporating an inlet tank, the corresponding fitting is located in the entrance of the exchanger, and a part incorporating a reservoir of outlet whose corresponding fitting is arranged in the exchanger outlet.
- the heat exchanger heat for gas consists of a carcass 1 of circular section containing a network of tubes 2 parallel, intended for the passage of gases to be cooled. AT inside the carcass 1 and outside the tubes 2 circulates a cooling fluid, ranging from a input 3 to output 4.
- the gases to be cooled enter the exchanger from a supply line 5 and through a tank input 6 which gradually widens.
- the inlet tank 6 is coupled to the conduit supply 5 by a connector 7, said tank inlet 6 and said connector 7 being integrated in a only piece made by stamping.
- the outlet tank 9 is coupled to the outlet conduit 8 through a connector 10, said outlet tank 9 and said connector 10 being integrated in one piece made by stamping.
- stamping to define complex shapes it is possible to design different configurations of the connection surface of the tank 6, 9 and the connection 7, 10, thereby improving the flow passage gaseous.
- connection surface of fitting 7 and the tank 6 has a concave or conformed configuration towards outside.
- connection surface of fitting 7 and the tank 6 has a convex or shaped configuration towards inside.
