Description
TURBULATOR WITH TRIANGULAR AIRFOILS INCREASING THE PERFORMANCE OF ENGINE INTERCOOLERS
TECHNICAL FIELD
This invention relates to intercoolers used for cooling air heated as a result of compression by a turbocharger unit in turbocharged engines. Particularly, the invention relates to a turbulator embodiment, increasing cooling efficiency by triangular turbulator airfoils located in a case of an intercooler used in new generation turbocharged engines in vehicles and thereby providing a higher combustion quality, improving fuel efficiency, increasing engine power and durability, and decreasing engine gas emissions.
STATE OF THE ART
In the state of the art, intercoolers are utilized to cool air, heated as a result of turbo compression in turbocharged engines. Air let into the engine in vehicles with turbocharged engines first goes through an air filter. Intake air flows into the turbocharger after combustion in cylinders and hot air exiting therethrough is pumped into an intercooler. Air passing through wide surfaces and narrow channels, being mixed in the intercooler, is cooled by instant heat transfer. Air exiting an intercooler after being cooled re-enters through a gas inlet manifold. Intermolecular space is less when the air is cooled, that is the number of molecules in unit volume is higher. More air (oxygen) fits into a cylinder when the air let into the cylinder is cooled and thus more power is obtained by improving volumetric efficiency.
The desired cooling performance in the intercoolers of vehicles with Euro5 / Tier3 emission engines enacted in 2008 was that outlet air temperature should be at a measure of + ~ 40 Ό. It was estimated that this te mperature provided the exhaust emission values required for engine efficiency and clean environment. Turbulators (10) of prior art visible in Figure 4 were sufficient to meet the necessary requirements. Cooling requirements for vehicles with Euro6 / Tier4 emission new generation engines have increased significantly, however the space allocated to
intercoolers have stayed the same. Present turbulator embodiments have become insufficient as there is need for more cooling in the same space. In present turbulators (10), there are airfoils (12) in square or rectangular form located in prior art tubes (1 1 ).
An intercooler's being big and having increased contact surfaces means that it can cool more air. The fact that the size of the intercooler in new generation engines remained the same made it essential for the design of the turbulator be improved, the contact surfaces and the turbulence property be increased in order to increase the cooling capacity.
In a literature review carried out in relation to the subject, application number TR200504483 was found. The invention relates to an intertubular support element. It is stated in the published abstract of the invention that: "The invention relates to an air intercooler embodiment, cooling the air sent to the engine in diesel vehicles, consisting of a tube, a turbulator, fins, side panels and a tray, characterized in that; it comprises at least one support element between the turbulator and the tube located within a tube, wherethrough the air to be cooled passes." Examining the turbulator located in the support element subject to the invention, it is observed that it comprises airfoils of square form.
Application number TR200100997 relates to a turbulator providing fuel efficiency in automobiles. It is stated in the abstract of the invention that: "The turbulator consists of a circular outer casing with an open end, a circular inner casing and fifteen turbulating airfoils with a special design all made of substantially stainless steel material. Size of casings and shape of airfoils may differ according to the brand of the car, and the structure of the carburettor and inlet manifold."
As a result; improvements are made on intercooler turbulators, thus new embodiments are required to eliminate the aforementioned disadvantages and bring solutions to the existing systems.

Another object of the inventions is to obtain a better combustion quality with the fuel and charged air intake into the engine combustion chamber by means of an intercooler increasing the cooling capacity.
Another object of the invention is to improve combustion fuel efficiency by obtaining optimum fuel-air mixture by means of improving the cooling capacity of the turbulator.
Yet another object of the invention is to increase the engine power and durability by means of air cooled efficiently at the intercooler.
The aim is to decrease gas emissions and minimize environmentally hazardous gas outlet by improving combustion quality by means of increasing the cooling capacity of the turbulator in the intercooler. Still another object of the invention is to increase the cooling capacity of the intercooler in order to increase the air entering (air intake temperature ~ 180-200 Ό) the intercooler from the turbo charger unit in Euro6 / Tier4 engines so that the engine efficiency and exhaust emission values required for a clean environment are obtained.

DETAILED DESCRIPTION OF INVENTION
In this detailed description, preferred embodiments of an intercooler (1 ) subject to the invention is described only for the purpose of better understanding and without inserting any restrictive effects.
This invention relates to an improvement for increasing the cooling efficiency in an intercooler (1 ) used for cooling the air heated as a result of compression by a turbo in turbocharged engines. Figure 1 shows a 3-dimensional view of an intercooler comprising a turbulator (5) subject to the invention with triangular airfoils. According to this, an intercooler (1 ) comprises an inlet opening (2) and an outlet opening (3). Inlet opening (2) is the part wherethrough compressed air coming from the turbocharger unit of the engine enters the intercooler (1 ). Outlet opening (3) is the part wherethrough cooled air in the turbulator (5) exits. Tubes (4) of square form are present in an intercooler (1 ) arranged one top of another successively between an inlet opening (2) and an outlet opening (3). Turbulators (5) performing the cooling process of an intercooler (1 ) are located within said tubes (4).
Figure 2 shows a three dimensional view of a turbulator (5) located within a tube (4). A turbulator (5) subject to the invention consists of triangular bodies (5.1 ) having a zig-zag formation with the combination of triangular "V" forms arranged successively located in a tube (4) and triangular side airfoils (5.2) arranged thoroughly on surfaces of said triangular bodies (5.1 ). Figure 3 shows a detailed view of a triangular body (5.1 ) and triangular side airfoils (5.2). Working principle of an intercooler (1 ) comprising a turbulator (5) with a triangular body (5.1 ) is as follows:
Air compressed by a compressor in the turbocharger unit of the engine has a high temperature and needs an intercooler (1 ) to be cooled. Heated air coming from the
turbocharger unit enters through the inlet opening (2) of an intercooler (1 ), and proceeds through turbulators (5) within tubes (4). The aim of a turbulator (5) is to create turbulence by mixing the air as much as it can, and to let maximum heat transfer possible on the surface. Heated air entering the turbulator (5) is turbulated while going through a triangular body (5.1 ) and triangular side airfoils (5.2) on the surfaces of said triangular bodies (5.1 ), and meanwhile heat transfer is actualized. Thereby, temperature of heated air entering in the intercooler (1 ) through the inlet opening (2) drops radically when it reaches the outlet opening (3). The structure of the turbulator (5) with triangular airfoils according to the invention resulted in an increase in contact surface compared to square and rectangular forms in the state of the art. Increased contact surface helps heat transfer to be carried out more rapidly. In addition, maximum mixture of air passes through both the triangular body (5.1 ) and triangular side airfoils (5.2) on the triangular body (5.1 ). Thus, as the turbulator (5) creates a higher level of turbulence, an increase in heat transfer is obtained accordingly.
Cooling capacity of an intercooler (1 ) in increased by 20% by means of the turbulator (5) embodiment with a triangular airfoil form according to the invention. It is possible to obtain a more optimum fuel - air mixture as there is more oxygen in unit volume as the air cools down and thus higher combustion quality with enriched air fuel mixture entering the engine combustion chamber. This will also contribute to improving fuel efficiency, increasing engine power and durability, decreasing gas emissions and minimizing environmentally harmful gas exhaust.
The turbulator (5) embodiment according to the invention provided to reach a cooling capacity of the intercooler (1 ) increase the air exiting (air intake temperature ~ 180-200 Ό) the turbo charger unit in Euro6 / Tie r4 engines so that the engine efficiency and exhaust emission values required for a clean environment are obtained.
