Technical Field

The invention relates to a turbulator, which provides an enhancement in the efficiency of the cooling of air of the engine air cooler in the motor vehicles.

The invention specifically is related to a turbulator which provides an enhancement in the air turbulence which goes through the engine air cooler and the efficiency of the cooling depending on the turbulence for the vehicles comprising Euro 6 type engine.

Prior Art

In motor vehicles, fuel and air mixture is used in order to provide that the combustion is achieved within the engine system. In order for the combustion process to occur more efficiently, it is needed that the air which is mixed with the fuel is rich oxygen-wise. For this purpose, the air, which is sent into the engine air cooler (inter-cooler) by a turbo system which enhances the transmission speed of the air, is transferred to the engine combustion cells by being cooled inside the engine air cooler. The density of the cooled air increases and consequently it can comprise a greater amount of oxygen within it. Due to the high oxygen rate of the air which is cooled inside the said engine air cooler and sent to the engine combustion cells, a rich mixture with the fuel is obtained and an improved combustion process is achieved.

In order to cool the air in the engine air cooler, the turbulator, which is located inside the tubes in the said engine air cooler, is used. The turbulator enhances the turbulence (fluctuation) of the air which goes through the said tube and decreases the passing speed of the air and increases its contact with the surface. By this way, the rate of heat transfer between air and the surface that it contacts enhances, and it is achieved that the air exits the said engine air cooler in a cooled manner.

Today, in order to decrease the amount of the toxic gas (emission) that is released into the air, Euro 6 type engines are used in motor vehicles, instead of Euro 5 type engines. However; the temperature of the air that is sent from the engine air cooler to the combustion cells is much higher in Euro 6 type engines in comparison with the air temperature in Euro 5 type engines. On the other hand, the space volume that is dedicated for the engine air cooler to be located remains the same in Euro 6 type engines and therefore, the turbulators that are used in the prior art become insufficient for the cooling of the said air with high temperature in the Euro 6 type engines. This results both in that the engine consumes more amount of fuel and more amount of toxic gas is released to the air.

As a result, an improvement of a turbulator, which enables that the air, which is sent to the combustion cells, is cooled in an improved manner inside the engine air cooler and consequently enhances the efficiency of the engine performance and decreases the fuel consumption and the amount of the toxic gas that is released to the air, is needed for vehicles comprising Euro 6 type engines.

Aim of the Invention

The present invention is related to a turbulator, which fulfills the above-mentioned needs, eliminates the possible disadvantages and provides some additional advantages.

The main aim of the turbulator of the invention is to create a turbulence by enabling the air, which is sent to the combustion cells, fluctuates inside the engine air cooler and by this manner, to cool the advancing air in a more improved manner in the vehicles. In addition to that, with the enhancement of the engine performance by a more improved cooling of the air; a turbulator, which decreases the fuel consumption and the amount of toxic gas that is released to the air, is achieved.

Another aim of the invention is to provide a turbulator which operates effectively and efficiently, and which is suitable for being located inside the air transmission tubes with different sizes.

In order to achieve the above-mentioned goals in the most general manner the said turbulator comprises a first side with a first length value and a second side, which are located parallel to the lying direction of the said air tube and to each other and which are located opposite to each other with a distance between them; and at least one surface in a quadrangle plate form; which comprises at least one first conduit which is located on the surface that is located between the first side and the second side in a manner that it is connected to the said first side and the said second side, which is located with a distance of a second distance value from the surface which lies between the first side and the second side and in a manner to be parallel to the first side and the second side and which allows the airflow through itself, which is in a linear form in a second length value which is shorter than the said first length value and at least one second conduit which is parallel to the said first conduit, which is located on a direction that is different from the first conduit's and in a manner that it is located with a second length value from the surface that lies between the first side and the second side and which allows the airflow through itself, which is in a linear form in a third length value which is shorter than the said second length value.

Detailed Description of the Invention

In the motor vehicles, in order to enable a combustion inside the engine system and to enable the air which is mixed with the used fuel be rich oxygen-wise, it is provided that the air which is sent into the engine air cooler (inter-cooler) is cooled inside the engine air cooler and transmitted to the combustion cells. In order for the air to be cooled in the engine air cooler, a turbulator, which is located inside the tubes in the said engine air cooler, is used. The turbulator enhances the turbulence (fluctuation) of the air which goes through the said tube, and decreases the passing speed of the air and increases its contact with the surface. In this context, with the present invention, a turbulator which enhances the turbulence of the air which goes through itself, with the aim of enhancing the cooling efficiency of the engine air cooler in the vehicles comprising Euro 6 type engine.

The turbulator (T), of which the exemplary view is given in Figure 1 , which is developed with the present invention and which is suitable to be located inside the air tubes which are comprised by the engine air cooler in the vehicles; comprises: a first side (1 ) with a first length value and a second side (2), which are located parallel to the lying direction of the said air tube and to each other and which are located opposing to each other with a distance between them, at least one surface (3) in a quadrangle plate form; which is comprises at least one first conduit (3a) which is located on the surface that is located between the first side (1 ) and the second side (2) in a manner that it is connected to the said first side (1 ) and the said second side (2), which is located with a distance of a second distance value from the surface which lies between the first side (1 ) and the second side (2) and in a manner to be parallel to the first side (1 ) and the second side (2) and which allows the airflow through itself, which is in a linear form in a second length value which is shorter than the said first length value and at least one second conduit (3b) which is parallel to the said first conduit (3a), which is located on a direction that is different from the first conduit's (3a) and in a manner that it is located with a second length value from the surface that lies between the first side (1 ) and the second side (2) and which allows the airflow through itself, which is in a linear form in a third length value which is shorter than the said second length value.

In an exemplary application of the turbulator (T) which is developed by the invention, the said turbulator (T) is located inside the air transmission tube in the engine air cooler.

The hot air that is sent to the engine cooler passes through the first conduit (3a) and the second conduit (3b) when advancing inside the air transmission tube. Due to the fact that the first conduit (3a) and the second conduit (3b) are located parallel to each other but in different directions, a turbulence is created by the fluctuation of the air during its movement between the first conduit (3a) and the second conduit (3b). By the created turbulence, a decrease in the speed of the air which moves through the air transmission tube is achieved and it is enabled that the air hits to the surfaces of the first conduit (3a) and the second conduit (3b) and therefore the heat transfer is enhanced. By this manner, a turbulator (T), which enables the air going through the engine air cooler to be cooled in a more efficient manner, is achieved.

In a preferred exemplary application of the invention, in order to increase the fluctuation of the air which moves along the surface (3) of the turbulator (T), it comprises at least two first conduits (3a) which are located parallel to the first side (1 ) and at least two second conduits (3b) which are parallel to the first conduits (3a) and each of these second conduits are located suitably to transfer air into the at least two first conduit (3a).

In another preferred exemplary application of the invention, the turbulator (T) comprises at least one first conduit (3a) of which the perpendicular cross-section to the direction of the first side (1 ) and the surface is in“U” form and at least one second conduit (3b).

In another preferred exemplary application of the invention, in order for the volume inside the air tube to be used efficiently, the turbulator (T) comprises at least one surface (3) which comprises at least one first conduit (3a) and at least one second conduit (3b) which are located in a distance, with a distance value of a third distance value which is more than the said second distance value, from the surface that lies between the first side (1 ) and the second side (2).

Due to the locations of the first conduit (3a) and the second conduit (3b) which are comprised by the turbulator (T) developed by the present invention, a turbulence is created by enabling the air fluctuate during its movement between the first conduit (3a) and the second conduit (3b). By this manner, it is enabled that the turbulator (T) inside the engine air cooler decreases the speed of the air and consequently; due to the fact that the air is enabled to contact with more surfaces, a more efficient cooling of the air which goes through the engine air cooler is achieved. Therefore; a turbulator (T), which provides a better air cooling, decreases the fuel consumption and the release of toxic gas into air and operates more efficiently and effectively, is achieved.
