CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 61/487,645 filed May 18, 2011, which is incorporated in its entirety by reference into this application.

FIELD OF THE INVENTION

The present invention relates generally to the field of vehicle performance parts. More specifically, the present invention relates to an apparatus and system to maximize airflow through a vehicle intercooler.

BACKGROUND OF THE INVENTION

On any given vehicle, there are thousands of functioning and necessary parts. These essential parts are usually interlinked with other parts of an overall system to make a vehicle run efficiently.
For many car enthusiasts, modifying a factory vehicle with upgraded aftermarket parts is rewarding and satisfying in a multiplicity of different ways. Many individuals decide to modify their vehicles for aesthetic purposes. However, many individuals modify or alter their vehicles to elicit better performance from their vehicle or to upgrade from more restrictive parts that come with their vehicle from the factory to less restrictive parts with better usability and/or performance.
There are some common aftermarket modifications that most vehicle enthusiasts, such as car owners, motorcycle owners, boats, and other gasoline/diesel powered vehicle owners choose to employ. A few of these common aftermarket modifications are replacement of a vehicle exhaust system and replacement of headers (tubes that run from the engine and direct unwanted heat and exhaust away from the engine). Additionally, many individuals will recalibrate a vehicle's computer which regulates engine speed and other functions, to elicit higher performance and tolerances. Another common type of vehicle modification is the replacement of the stock air filter with an aftermarket air filter. However, a problem with modifications is that they are limited in their ability to produce the desired increase in power and performance.
When an individual user decides on increasing power and performance, thereby increasing the performance of the vehicle outside of what the original manufacturer had anticipated when they produced the vehicle, it is necessary to modify the vehicle with parts that were not intended. For example, one of the more widely utilized forms of increasing performance on any vehicle is to utilize forced induction by either turbocharging the vehicle or supercharging the vehicle.
A turbocharger is a type of gas compressor used to increase the pressure of air entering the engine of a vehicle. The turbocharger is usually made of at least a turbine, and often times by multiple turbines that is driven by the engine's exhaust gases. In contrast, a supercharger is powered by mechanical drive. This allows a turbocharger to compound various cycles to achieve greater power or higher efficiency or both.
On the other hand, a supercharger is an air compressor that forces more air into the engine of a vehicle. The greater mass flow-rate provides more oxygen to support combustion than would be available in a non-supercharged engine. This supercharging capacity allows for more fuel to be burned by the engine and increases the power output of the engine. Power for the unit can come mechanically by a belt, gear, shaft, or chain connected to the engine's crankshaft.
However, one problem that exists with a forced induction system is heat. Turbo chargers utilize an engine's exhaust gases after the liquid gas has been heated and burned by the engine. Similarly, supercharges force more air into the engine of the vehicle and cause more fuel to be burned by the engine, thereby creating more exhaust gases, and in turn, more heat.
In an effort to solve this heating problem, manufacturers of forced induction systems have created a cooling system for these vehicles having forced induction systems (such as turbochargers and superchargers). Intercoolers have attempted to solve some of these heating problems.
An intercooler is an air-to-air or air-to-liquid heat exchange device utilized in combination with turbocharged or supercharged systems on vehicle engines to improve their volumetric efficiency by increasing intake air charge density through nearly constant pressure cooling, which removes the heat of compression that occurs in any gas when its pressure is raised or its unit mass per unit volume is increased. A decrease in intake air charge temperature sustains use of a more dense intake charge into the engine, as a result of supercharging. The lowering of the intake charge air temperature also eliminates the danger of pre-detonation of the fuel air charge prior to timed spark ignition, thus preserving the benefits of more fuel/air burn per engine cycle and increasing the output of the engine. Intercoolers increase the efficiency of the induction system by reducing induction air heat created by the turbocharger and promoting more thorough combustion. They also eliminate the need for using the wasteful method of lowering intake charge temperature by the injection of excess fuel into the cylinders' air induction chambers, to cool the intake air charge, prior to its flowing into the cylinders. This wasteful practice nearly eliminated the gain in engine efficiency from supercharging, but was necessitated by the greater need to prevent the engine damage that pre-detonation engine knocking caused.
However, a problem with prior art intercoolers is that air flow and air to liquid flow must be maximized in order to maximize cooling and therefore, performance of a forced induction system. Thus, to maximize the benefits of utilizing air flow, a large intercooler must be utilized. However, prior art intercoolers have limitations on the amount of airflow and the efficiency of air flow through the intercooler because of their design.
A need therefore exists for an improved apparatus and system for producing an intercooler that may maximize and greatly increase flow through the intercooler. Additionally, a need therefore exists for an improved apparatus and design for an intercooler to maximize flow and increase performance of an entirety of a forced induction system.

DETAILED DESCRIPTION

The present invention relates to an apparatus and a system that may be utilized to maximize and utilize greater air flow through an intercooler apparatus. The present invention utilizes unique coil configurations and designs to help promote better air flow through an intercooler apparatus. The present invention utilizes unique profiled passage separators to improve air flow through the passages of the intercooler. Additionally, the present invention utilizes profiled passage separators that improve and significantly cool temperatures of the air flow in much smaller packaging because of the unique passage separators and air flow design of the intercooler.
FIG. 1 shows a heat exchange apparatus 100 in accordance with an embodiment of the present invention. In an exemplary embodiment of the present invention, an apparatus for cooling air to the engine of a vehicle is provided. Air flow 140, as hot air, enters the heat exchange apparatus through the hot fluid inlet end 110 of the end tanks 125. The specially designed shape of the end tanks 125 increases volumetric efficiency. Heat build-up is reduced, which keeps the intake charge cool. Smooth internal features minimize air turbulence and maximize air flow. By correctly shaping the entry into and out of the heat exchange apparatus 100, air flow is greatly increased. A more efficient intercooler lets the turbo and the motor run far cooler and produce more power.
In an exemplary embodiment, the apparatus 100 can be uniquely small as compared with the prior art intercooler designs because current intercooler technology is based on size for an application, so the higher the heat rejection requirement the larger the intercooler. With the current state of art in intercoolers, most other heat exchanging devices do not pay attention to the fluid flow entering and exiting the core of the exchanger. The unique design of the present apparatus allows for greater fluid flow through the intercooler to more adequately cool without the need for a larger sized intercooler apparatus.
FIG. 2 shows the internal portion 150 of the heat exchange apparatus 100 in accordance with an embodiment of the present invention. The coil configuration 120 may be seen in both the side and front view of the apparatus 100. Profiled passage separators 105 on the front and side of the apparatus 100 provide a shaped entry profile into each internal air passageway 135 by forming bars of material, preferably being a metal or substantially rigid material, that separate each passage. Each passageway is separated from another passageway by a profiled passage separator 105. This structure serves to reduce the dimensions of the vena contracta in the flow path. Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum.
FIG. 3 is a front cross-sectional view of the internal portion 150 in an exemplary embodiment of the present invention. The heat exchange apparatus 100 has a plurality of fluid flow passages that allow for cooling of the fluid flow there through and further wherein the passageway 135 has at least a hot fluid side inlet end 110 and a cooled fluid discharged end 115. Air flow 140 is seen entering the end tanks 125 of the heat exchange apparatus 100 at the hot fluid inlet end 110, passing through the cooling fluid passageways 135 by shaped entry due to the convex surfaces, and exiting at the cooled fluid discharge end 115. In an exemplary embodiment, a heat exchange apparatus is provided whereby the same profiles can be applied to the hot side and cold side of the intercooler. The concept is to provide a shaped entry profile into each internal air passageway 135 by forming the bars of material, profiled passage separator 105, that separate each passage. The heat exchange apparatus 100 has a plurality of fluid flow passageway 135 that allow for cooling of the fluid flow there through. The passageways have a distal portion and a proximal portion each ending with a uniquely configured abutment, preferably in the form of a convex surface 130.
FIG. 4 is a close-up view of the heat exchange apparatus 100 illustrating the profiled passage separators 105 in an internal portion 150. In an exemplary embodiment, the apparatus has a passageway 135 whereby fluid flow is channeled there through and cooling of the fluid flow is affected. The apparatus 100 utilizes convex shaping of the passageways of the intercooler to greatly improve air flow through the apparatus 100. Air flow 140 enters the hot fluid inlet end 110 by being funneled past the convex surface 130 of the profiled passage separators 105.
FIG. 5 is another close-up view of the heat exchange apparatus 100 illustrating the profiled passage separators 105 in an internal portion 150. The cooling fluid path 145, beginning at the hot fluid inlet end, ends at the cooled fluid discharge end 115. The apparatus applies basic fluid mechanics to the entry and exit of the hot side passages of the heat exchangers to improve air flow through the heat exchangers. The apparatus correctly and uniquely shapes the entry into and out of the passageway 135 of the apparatus 100 to greatly increase air flow.
Thus, specific embodiments and applications of a intercooler system have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. The terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced.
