Description

BACKGROUND OF THE INVENTION Area of ​​the invention

[0001] The present invention relates to a wind flow concentration and guidance device, and in particular a wind flow concentration and guidance device which can significantly increase the cooling capacity of an intercooler or charge air cooler by increasing the amount of wind flowing in, as well as an engine compartment layout or an engine compartment arrangement with an optimized layout or structure. Description of related technology

[0002] Typically, an air intake or air intake device that draws in outside air flowing through an air filter, an intake system which has an intake manifold that is connected to a combustion chamber, a condenser from a cooling device and a radiator from an engine cooling system are arranged around an engine, in particular an internal combustion engine, which is located in an engine compartment.

[0003] Unlike gasoline vehicles, the intake system of a diesel engine and a gasoline turbo engine includes a turbocharger to increase the engine's power by compressing the outside air. Along with the turbocharger, an intercooler or charge air cooler is also provided to cool the compressed air flowing out of the turbocharger.

[0004] Typically, a turbocharger has an exhaust gas recirculation device connected to a turbine, an air intake connected to a compressor, and the charge air cooler is positioned to capture / receive wind effectively in order to increase wind cooling performance.

[0005] In diesel and gasoline turbo engine vehicles, since the charge air cooler is located near or adjacent to the front end part (or front end part) of the front of the engine compartment, along with the condenser and radiator, it is possible to increase the cooling capacity from the wind flowing into the engine compartment when the vehicle is in motion.

[0006] As the cooling power of the wind increases, the condenser can increase the cooling power for the interior of the vehicle, the radiator can more easily prevent the engine from overheating or running hot, and the charge air cooler can improve the engine's output power and fuel efficiency with high efficiency.

[0007] As described above, an effective inflow of wind increases the cooling capacity of the condenser and radiator, and especially the cooling capacity of the charge air cooler, which is very important to improve the engine's output power and fuel efficiency.

[0008] Therefore, it is necessary to provide a larger open area at the front end to direct or feed a greater amount of wind to the condenser, radiator, and charge air cooler.

[0009] However, since a radiator grille and a bumper are located at the front of the front-end part, the front-end part is very important for the external appearance of the vehicle.

[0010] Therefore, an expansion of the open area from the front end part to increase the amount of wind flow is inevitably restricted, especially by the degree of freedom of the external appearance, and the restriction is inevitably linked to a limit on increasing the cooling capacity of the charge air cooler using only the wind.

[0011] However, a high-performance engine with increased power requires a corresponding high-efficiency intercooler, and it is necessary to improve the cooling performance of the intercooler using wind to increase the efficiency of the intercooler without upgrading the specifications.

[0012] The information disclosed in this background of the invention section is provided solely for the purpose of better understanding the general background of the invention and should not be construed as an endorsement or any other form of suggestion that this information constitutes the prior art already known to those skilled in the art.

[0013] Furthermore, for example from DE 102 09 237 A1, a wind flow concentration and guidance device is known which is configured to introduce wind flowing through a radiator grille located on the top of a front end part forming a front section of an engine compartment and to discharge it to an inlet system located in the engine compartment, and which is further configured to introduce wind flowing to a bumper section located on the underside of the front end part, and wherein the wind flow concentration and guidance device has a main shaft, a lower shaft and a branch shaft.

[0014] Furthermore, an air guide is known, for example, from DE 102 48 440 A1, which is configured to introduce wind flowing through a radiator grille located on the upper side of a front end section forming the front of an engine compartment, and which is further configured to introduce wind flowing to a bumper section located on the underside of the front end section. Another air guide is known, for example, from JP H10-252 485 A. BRIEF EXPLANATION

[0015] The present invention is directed to provide an airflow concentration and guidance device (or a device for selectively introducing wind into the engine compartment) which can significantly increase the amount of wind entering the vehicle without compromising design freedom regarding the external appearance of the front of the vehicle, which can increase the cooling capacity for a condenser and a radiator by concentrating or directing the airflow or wind stream onto the condenser, radiator and charge air cooler, and which in particular can efficiently increase the performance of the charge air cooler using only the wind, in order to meet the demands of a high-performance engine without increasing the specifications of the charge air cooler.

[0016] Furthermore, the present invention is directed to provide an engine compartment layout or arrangement or structure which is equipped with a windflow concentration and guidance device which can improve the wind cooling performance for the engine compartment and which greatly increases the inlet / intake performance by directly directing a portion of the wind directed to the engine compartment to an air inlet, and consequently the structure of the engine compartment can be optimized for arranging a condenser, a radiator and an intake system.

[0017] According to the invention, a wind flow concentration and guidance device with the features of claim 1 and an engine compartment arrangement with the features of claim 6 are provided. Further embodiments of the wind flow concentration and guidance device and the engine compartment arrangement are described in the respective claims.

[0018] This means that an airflow concentration and guidance device is provided into which wind can flow / be introduced that passes through a radiator grille located on the top of a front-end part forming a front section of an engine compartment, and which is configured / arranged / structured to deliver or expel the wind to two different parts of an intake system located in the engine compartment, and into which wind can flow to a bumper section located on the bottom or underside of the front-end part, the device being configured to deliver the introduced wind to one (e.g., exactly one) of the two different parts.

[0019] One of the two distinct parts of the intake system is an intercooler or charge air cooler, which cools compressed air from a turbocharger, and the other part is an air intake or air intake device, which introduces outside air.

[0020] A main duct or main shaft has an inlet located near the grille to draw in the airflow passing through the grille, and an outlet positioned at or directed towards the top of the intercooler. A sub- or secondary shaft / duct allows the airflow to pass through one or more positions to draw in the airflow heading towards the bumper section. A branch or divert duct / duct is connected to a main shaft wind channel to divert or divert a portion of the airflow drawn into the main shaft before it exits the main shaft outlet, and may direct the diverted airflow to the air intake.

[0021] The main shaft is an open channel inclined at an angle, with the inlet positioned higher than the outlet. The sub-shaft is an open channel comprising a lower inlet shaft and an upper inlet shaft, which project outwards at one side to introduce the wind flowing towards the bumper section. The branch shaft is an open channel connected to the main shaft's wind tunnel.

[0022] The upper inlet shaft of the lower shaft and the branch shaft may have different inlet and outlet cross-sections to have funnel-shaped cross-sections, wherein the inlet cross-sections may be narrower or smaller than the outlet cross-sections, and wherein an inlet cross-section of the lower inlet shaft may be approximately or substantially equal to its outlet cross-section.

[0023] The wind introduced into the lower inlet shaft and the upper inlet shaft of the sub-shaft can be collected or combined when it is / has been expelled from the sub-shaft.

[0024] Furthermore, the engine compartment layout or engine compartment arrangement is provided, which uses an airflow concentration and guidance device, wherein the engine compartment arrangement comprises: the airflow concentration and guidance device, an intake system comprising an air intake that introduces outside air, the turbocharger which is connected to an external gas recirculation device (or an exhaust gas recirculation device), and the charge air cooler which cools compressed air and directs the air to an intake manifold, and which is arranged in an engine compartment, and a cooling module which may include a condenser for a cooling device and a radiator for an engine cooling system and which may be arranged on one side of or next to the intake system.

[0025] The cooling module can be cooled directly by the wind passing through the radiator grille located at the front end, and the wind flow concentration guide device can be located on one side of the radiator grille to avoid interfering with or disturbing the flow of wind directly to the cooling module.

[0026] The wind current concentration and guidance device can be combined / connected or held together by a shaft frame or shaft structure located at the front end part.

[0027] The main duct of the windflow concentration guide device can be positioned on one side of the radiator grille, the branch duct from the main duct can be directly connected to the air intake, and the lower inlet duct of the lower duct can be positioned on a bumper support section on which a bumper can be arranged in a bumper section, with the upper inlet duct being positioned around or on an intermediate support which is arranged at a predetermined distance to / from the bumper support section.

[0028] An air intake, which may be an open space surrounding the lower intake duct and allowing wind to flow in, may be formed on the bumper bracket.

[0029] The present invention has the advantage that the cooling capacity can be considerably increased by increasing the amount of wind flowing to a condenser, a radiator and an intercooler, and in particular, a high-efficiency operation of the intercooler is implemented or enabled, which is required for a high-performance engine, and this can be done exclusively or solely with wind cooling.

[0030] The present invention has the advantage of increasing the efficiency of the charge air cooler by using wind, without having to upgrade the specifications of the charge air cooler, while reducing the outlet temperature of the charge air cooler under the same conditions.

[0031] The present invention has the advantage that the inlet / intake performance is significantly increased by directly introducing a portion of the wind flowing into the engine / internal combustion engine into the air inlet, and that the layout of the engine compartment is optimized by optimally designing / arranging the condenser, cooler, and inlet system in a single-analysis system using the wind flow in a wind flow concentration and guidance device.

[0032] The devices of the present invention have further advantages, which are evident from or detailed in the attached drawing included herein, as well as in the following detailed description, which together serve to explain certain principles of the present invention. BRIEF DESCRIPTION OF THE DRAWING The Fig. 1A and Fig. Figure 1B shows the configuration of a wind stream concentration and guidance device according to an exemplary embodiment of the present invention. The Fig. 2A and Fig. 2B are views showing an engine compartment layout or arrangement for a condenser, a radiator and an inlet system equipped with the windflow concentration and guidance device according to an exemplary embodiment of the present invention. Fig. Figure 3 is a view showing the airflow in an engine compartment, which is generated by the wind flowing through the airflow concentration guide device and a radiator grille.

[0033] It should be understood that the attached drawing is not necessarily to scale, but rather a somewhat simplified representation of various features that illustrate the basic principles of the invention. The specific design features of the present invention, as disclosed herein, including, for example, specific dimensions, orientations, arrangements, and shapes, are partly determined by the intended application and environment of use.

[0034] In the figures, the same reference numerals denote similar or equivalent parts of the present invention. DETAILED DESCRIPTION

[0035] The following section refers in detail to various embodiments of the present invention, examples of which are shown in the attached drawing and described below. While the invention is described in connection with exemplary embodiments, it should be understood that the present description is not intended to limit the invention to these exemplary embodiments.

[0036] With reference to Fig. 1A can direct a wind current concentration and guidance device 20 wind, which flows in through or at / from at least three different positions, to an inlet system in an engine compartment through or at at least three different positions / points or to expel it.

[0037] For this configuration, the wind flow concentration and guidance device 20 has a main shaft 30 through which wind flows, a sub-shaft or secondary shaft 40 through which wind flows, which enters from / at at least one or more positions below the main shaft 30, and a branch shaft 50 which is connected to the upper section of the main shaft 30 to generate a wind flow that is different from the wind flow passing through the main shaft 30, by branching or diverting a portion of the wind passing through the main shaft 30.

[0038] The main duct 30 has an open channel structure for drawing in / introducing part of the wind flowing through a radiator grille at the upper end of the front-end part, and delivering / expelling it to the intake system in the engine compartment, and the main duct 30 is inclined at a predetermined angle K such that the inlet through which the wind flows is positioned higher than the outlet for expelling the wind.

[0039] The main shaft 30, for example, has a completely uniform rectangular or right-angled cross-section, and the cross-section of the inlet through which the wind flows in has the shape of a distorted or deformed rectangle, with one vertical side and one horizontal side inclined to fit the side shape of the radiator grille or the shape of the radiator grille on one side thereof.

[0040] In the embodiment used as an example, the wind expelled or emitted from the main shaft 30 forms a flow path to the upper section of the charge air cooler from the intake system.

[0041] The lower duct 40 has an open channel structure for drawing in / introducing the wind flowing around / to the bumper section under the radiator grille at / from two different positions / locations and for expelling / releasing the wind to / to the intake system in the engine compartment, and for this operation the lower duct 40 has a pair of an upper intake duct 42 and a lower intake duct 41, which are spaced apart from each other.

[0042] The lower inlet shaft 41 and the upper inlet shaft 42 project from one side of the lower shaft 40 in a cylindrical shape, with an open gap or space between them, and are positioned on the lower section and the upper section of the lower shaft 40, respectively.

[0043] The wind flowing into the lower inlet shaft 41 and the upper inlet shaft 42 is expelled / released through an opening on the opposite side of the lower shaft 40, where the lower inlet shaft 41 and the upper inlet shaft 42 are not formed, to the inlet system in the engine compartment.

[0044] The inlet of the lower inlet shaft 41 and the inlet of the upper inlet shaft 42 are trapezoidal in shape, and the lower inlet shaft 41 has a uniform cross-section with the same width as the lower shaft 40, whereas the upper inlet shaft 42 has a cross-section that gradually widens or broadens to match or adapt to the width of the lower shaft 40 at the inlet.

[0045] This means that the inlet and outlet of the lower inlet shaft 41 have cross-sections of the same dimensions or cross-sections of the same size, whereas in the upper inlet shaft 42 the inlet cross-section is narrower than the outlet cross-section, forming a complete funnel shape.

[0046] In the embodiment used as an example, the wind emitted / expelled from the lower shaft 40 forms a flow path to the lower section of the charge air cooler of the intake system.

[0047] The branch shaft 50 is an open channel extending from the inlet connected to the wind path of the main shaft 30, so that it receives part of the wind passing through the main shaft 30 and directs it to another part.

[0048] The inlet of the branch shaft 50, which is connected to the wind path of the main shaft 30, has a rectangular or right-angled cross-section, with one horizontal side distorted / deformed, and the branch shaft 50 has a cross-section that widens from the inlet connected to the wind path of the main shaft 30 towards the outlet, forming a complete funnel shape.

[0049] The wind expelled from the branch shaft 50 or diverting shaft 50 is directed directly to an air inlet 2, for example an air inlet pipe 2 or an air inlet device 2, which is connected to the branch shaft 50, so that the inlet / intake performance of the air inlet 2 can be considerably increased.

[0050] With reference to Fig. 1B The wind flow concentration guiding device 20 can increase the cooling efficiency for the intake system by simultaneously drawing in / capturing and expelling a larger quantity of wind, and in particular can provide the power required for a high-performance engine without increasing the specifications of the charge air cooler by significantly increasing the cooling efficiency for the charge air cooler.

[0051] Consequently, the wind current concentration and guidance device 20 can draw in / capture wind simultaneously at at least three different positions by forming one wind inlet stream C through the main shaft 30 and two wind inlet streams A and B through the sub-shaft 40.

[0052] The main shaft 30 wind inlet flow C is formed by capturing the wind flowing through one side of the radiator grille at the top of the front end part (or front end section) which forms the front section of the engine compartment.

[0053] In the lower shaft 40 are formed: a wind inlet stream A of wind, which flows through the bumper section at the bottom or underside of the front end part, which forms the front section of the engine compartment, from the lower inlet shaft 41, and a wind inlet stream B of wind, which flows through the bumper section, from the upper inlet shaft 42, which is arranged at a distance from the lower inlet shaft 41.

[0054] The wind emitted by the wind stream concentration and guidance device 20 forms / comprises a wind emission stream Ca through the main shaft 30, another wind emission stream ab through the lower shaft 40, and another wind emission stream Cb through the branch shaft 50, so that the wind stream concentration and guidance device 20 can emit the wind simultaneously at or through at least three different positions.

[0055] The wind exhaust flow Ca from the main shaft 30 is a flow of wind that enters the main shaft 30 and immediately exits through the outlet, and the wind exhaust flow Ca creates a flow path that is concentrated or directed towards the upper section of the charge air cooler from the inlet system.

[0056] Since the main shaft 30 tilts or lowers at the predetermined angle K, with the inlet being higher than the outlet, the wind exhaust flow Ca is lower than the wind inflow flow C.

[0057] The wind exhaust flow ab in the lower duct 40 is a flow where the wind inlet flow A in the lower inlet duct 41 and the wind inlet flow B in the upper inlet duct 42 converge after the outlets. The wind exhaust flow ab creates a flow path which is directed or concentrated on the lower section of the charge air cooler from the inlet system.

[0058] The wind exhaust flow Cb in the diverting shaft 50 is a flow generated by a portion of the wind inlet flow C, which branches off to another portion before exiting the main shaft 30. The wind exhaust flow Cb flows directly to the air inlet 2, which is connected via the diverting shaft 50.

[0059] As described above, since the wind exhaust flow Cb flows directly to the air inlet 2, the inlet / intake performance of the air inlet 2 can be greatly increased.

[0060] With reference to Fig. 2A a cooling module 6 is arranged in the engine compartment together with the intake system 1, the charge air cooler 4 of the intake system 1 is positioned near the front-end part which forms the front section of the engine compartment, in particular on one side of or next to the cooling module 6, and the wind flow concentration guide device 20, which captures the wind flowing through the front-end part and expels the wind to the intake system 1, is positioned in front of the charge air cooler 4.

[0061] Therefore, the wind flowing through the front-end part simultaneously generates the current directly to the cooling module 6 and the current to the charge air cooler and intake system 1 through the wind flow concentration guide device 20, so that the cooling efficiency for the engine compartment can be significantly increased using the wind.

[0062] The intake system 1 has ordinary components, such as an air intake 2 (for example, an air intake device or an air intake pipe) which draws in or takes in the outside air through an air filter, a turbocharger 3 which compresses the outside air which is drawn in through the air intake 2 by means of an exhaust gas recirculation device, an intercooler 4 which cools the compressed air from the turbocharger 3, and an intake manifold 5 which conveys or directs the compressed air from the intercooler 4 to the engine, in particular an internal combustion engine.

[0063] Since in the exemplary embodiment the air inlet 2 is directly connected to the branch shaft 50 of the wind flow concentration and guidance device 20, the outside air can be directly taken in / drawn in by the wind flow concentration and guidance device 20.

[0064] The turbocharger 3 has a conventional structure, wherein the turbine is connected to the exhaust gas circulation device, and wherein the compressor is connected to the air inlet 2, and the charge air cooler 4 is arranged in the path from the turbocharger 3 to the inlet manifold 5 and cools the compressed air from the turbocharger 3.

[0065] The cooling module 6 forms the engine cooling system, wherein the condenser 6a forms the cooling device, and has ordinary components, such as a radiator 6b with cooling fan 6c, and the condenser 6a, the radiator 6b and the cooling fan 6c are arranged in sequence starting from the front end part at the front of the engine compartment.

[0066] With reference to Fig. 2A, the front end section, is connected at its lower end to the bumper section via a bumper bracket 11 and an intermediate bracket 12, and the radiator grille 13 is arranged at its upper end to allow air to flow into the engine compartment. Furthermore, a shaft frame or shaft structure 10 and the windflow concentration guide device 20 are arranged on the side to direct the air flowing through the bumper section and the radiator grille 13.

[0067] In the exemplary embodiment, the shaft frame 10 has a height which is essentially equal to that of the front end part, and is wide enough to accommodate the wind flow concentration and guidance device 20.

[0068] As described above, when the wind flow concentration guide device 20 is mounted on the front end part, the main duct 30 of the wind flow concentration guide device 20 is positioned on one side of the radiator grille 13, and the branch duct 50, which branches off or is routed from the main duct 30, is directly connected to the air inlet 2.

[0069] For this configuration, the radiator grille 13 has a grill structure or grate structure to allow the wind to flow through it, and the branch duct 50 or air intake 2 has a connecting structure by which the two can be connected.

[0070] In the lower shaft 40 of the wind flow concentration guiding device 20, the lower inlet shaft 41 is positioned / arranged on the bumper section bracket 11, and the upper inlet shaft 42 is positioned / arranged on the intermediate bracket 12.

[0071] For this configuration, the bumper section bracket 11 further has an air inlet 11a, which is an open space surrounding the lower inlet duct 41 and through which the wind flows, whereas the intermediate bracket 12 has a simple grid structure through which the wind can flow.

[0072] With reference to Fig.3 The wind flowing through the front end enters the engine compartment, divided into an exhaust air stream d, which has a path formed through the radiator grille 13 to the cooling module 6; exhaust air streams ab and Ca, which have paths formed from the side of the radiator grille 13 or from the bumper section to the charge air cooler 4 of the intake system 1 by means of the airflow concentration and guidance device 20; and an exhaust air stream Cb, which has a path branching off directly from the airflow concentration and guidance device 20 to the air intake 2.

[0073] In the exemplary embodiment, the wind passing through the radiator grille 13 flows directly into the cooling module 6 via the wind exhaust stream d, without any influence or interaction that directs / forces the wind into the wind stream concentration guiding device 20, so that the condenser 6a and the cooler 6b can be intensively cooled by the cooling module 6 via the wind exhaust stream d, thereby significantly increasing the cooling efficiency.

[0074] The wind discharge flow from the wind flow concentration guide device 20 is generated when the wind inlet flow A, which is generated in the lower inlet shaft 41 of the sub-shaft 40, through the air inlet 11a of the bumper section holder 11 and the wind inlet flow B, which is generated in the upper inlet shaft 42 of the sub-shaft 40, through the intermediate holder 12 connect / merge outside the sub-shaft 40.

[0075] The wind exhaust flow from flows to the inlet system 1 after it has intensively cooled the charge air cooler 4, flowing through the middle lower section of the charge air cooler 4.

[0076] The wind output stream Ca exiting the wind stream concentration guide device 20 is formed when the wind inflow stream C, generated in the main shaft 30, flows directly out of the main shaft 30 through the side of the radiator grille 13.

[0077] The wind exhaust flow Ca flows to the inlet system 1 after it has intensively cooled the charge air cooler 4, passing through the middle upper section of the charge air cooler 4.

[0078] As described above, using the wind flow concentration guide device 20, the wind exhaust flow exiting from the lower duct 40 can intensely cool the lower section of the charge air cooler 4, while the wind exhaust flow Ca exiting from the main duct 30 can intensely cool the upper section of the charge air cooler 4.

[0079] Therefore, the charge air cooler 4, which intensively absorbs a larger amount of wind, can be operated with high efficiency, which is needed for a high-performance engine, and the high efficiency of the charge air cooler does not affect the design freedom regarding the external appearance of the vehicle, which was necessary to allow a larger amount of wind to flow in.

[0080] In the exemplary embodiment, the wind discharge stream Cb, which exits from the wind discharge concentration guiding device 20, is shaped while flowing in and exiting the branch shaft 50 before the wind inflow stream C exits the main shaft 30.

[0081] Since the wind exhaust flow Cb flows directly to the air inlet 2, the inlet / intake performance of the air inlet 2 can be greatly increased.

[0082] As described above, in the exemplary embodiment, it is possible to significantly increase the cooling capacity of the cooling module 6 by using the airflow directed towards the cooling module 6, wherein the airflow concentration and guidance device 20 significantly improves the cooling capacity and eliminates irregularities in the flow of air passing through the charge air cooler 4 by shaping the airflow(s) which are concentrated / directed towards the upper section or the lower section of the charge air cooler 4, so that the airflow efficiency at the front end can be improved and the heat flow in the engine compartment can be optimized.

[0083] Therefore, the cooling performance and the inlet / intake performance can be advantageously improved, which is needed to improve the performance of the charge air cooler 4 when the engine power is increased.

[0084] For example, in related technology, a measure of improving only the individual functions of the charge air cooler 4, the cooling module 6 and the intake system 1 is applied by independently handling them to improve cooling performance and intake performance when increasing engine power, but an exemplary embodiment of the present invention can use a general or overall measure of improving the overall performance with an interaction and contribution by handling the intake system 1 with the cooling module 6 and the charge air cooler 4 as a single-analysis system.

[0085] The general measure can use various output elements for analysis, such as the amount of air, vehicle pressure, inlet pressure and inlet temperature, so that the accuracy of the test result can be significantly increased.

[0086] Experiments have shown that the outlet temperature of the charge air cooler is improved by 10% to 20%, depending on the type of engine, in terms of performance, and the capacity of the charge air cooler 4 is increased by approximately 35% to 55%, compared to a charge air cooler with the same specifications, depending on the type of engine.

[0087] In the exemplary embodiment, since the outside air intake flow is shaped by directly guiding the wind, which is captured or drawn in by the wind flow concentration guiding device 20, to the air inlet 2, it is possible to increase the inlet flow rate by reducing the inlet pressure when the vehicle is driving, and to improve the inlet temperature by preventing backflow of the inlet air at idle.

[0088] As described above, in the exemplary embodiment, since the windflow concentration and guidance device 20 introduces a larger quantity of wind and the open area of ​​the front end is optimized, the design freedom with regard to the vehicle's external appearance is not affected. Furthermore, the cooling module 6 and the inlet system 1 are optimally designed as a single-system analysis by using the windflow concentration and guidance device 20, thus allowing for optimization of the engine compartment layout.

[0089] For easier description and precise definition in the attached claims, the terms “top”, “bottom”, “inside” and “outside” are used to describe features of the exemplary embodiments with reference to their position in the figures.
