Description
- This invention relates to heat exchange system for cooling of intake air of internal combustion engines. More particularly it relates to a heat exchange assembly for V-configuration engines.
- It is recognised that the cooling of intake air for an internal combustion engine can dramatically improve the efficiency of operation of the engine and the power output as a result of the increased density of the air being admitted to the cylinders. This is particularly the case with supercharged or turbocharged engines where the intake air is pressurised by a mechanical operation. In both cases the supercharger or turbocharger results in a mechanical heating of the air during the process of compressing the air to provide an elevated pressure to the engine intake. The heat exchange assembly of the present invention has application to both supercharged and turbocharged engines and the term “compressor” will be used in the specification to refer to both such devices.
- Many engines, particularly those of higher capacity are constructed in the so-called V-configuration. In this configuration two banks of cylinders are arranged in a V-configuration so as to reduce the physical length of the engine. Configurations such as V-6, V-8 and V-12 are common and V-4 engines are also produced. Whilst the V-configuration reduces the overall length of the engine they do tend to result in a relatively tall engine. This is because it is normally convenient to have the intake manifold positioned in the V or valley between the banks of the cylinders so as to provide the intake air and or air/fuel mixture directly to the ports in the cylinder head. The exhaust ports are normally arranged on the remote sides of the cylinder heads for convenient connection to the exhaust system. Where it is desired to incorporate a heat exchange unit between a supercharger or turbocharger and an intake manifold in the valley between the cylinder heads space restrictions can be encountered. This can frequently result in the space between the top of the engine and the bonnet or hood of the car being insufficient for the necessary hardware. Consequently, modification of the bonnet or hood can become necessary. This is undesirable from a cost and aesthetic point of view.
- It is accordingly an object of this invention to provide a heat exchange assembly that will provide efficient cooling of the intake air without occupying a significant amount of space above a V-configuration engine.
- In one aspect this invention provides a heat exchange assembly for engines having cylinders arranged in two banks forming a V-configuration and having inlet ports from each bank of cylinders opening toward each other, said assembly including a generally rectangular housing having a top and a bottom extending between two opposed longitudinal sides, said opposed longitudinal sides including openings for communication with the inlet ports of said engine, an inlet in said top to receive a pressurised airflow from a compressor, and a heat exchanger formed by at least two mutually inclined components each also inclined with respect to the top and bottom of said housing to extend across and along said housing to define an inlet region adjacent said top of the housing and one or more outlet region(s) adjacent the bottom of the housing and said openings in each of said longitudinal sides, whereby air passing from said inlet to said openings passes through said heat exchange element.
- Preferably the components of the heat exchange element define a V-shape with the adjacent ends of the components located toward the bottom of the housing. It is further preferred that each of the components is inclined at about 30° to the bottom of the housing. Preferably the components extend adjacent to the bottom of the housing to substantially define two outlet regions each respectively adjacent one of the longitudinal sides. It is also preferred that the components of the heat exchange element are interconnected to form a single unit.
- Each component of the heat exchange element preferably includes respective heat exchange fluid flow paths. In a preferred form of the invention the respective fluid flow paths are configured to direct incoming heat exchange fluid to a central region of the housing. Preferably, the fluid flow paths subsequently direct the exchange fluid towards respective regions adjacent the longitudinal sides.
- In this preferred form of the invention the fluid flow configuration initially directs the coolest heat exchange fluid to the central region of greatest airflow.
- The housing is adapted to cylinder heads of the engine. That is, the housing takes the place of the intake manifold and extends substantially across the valley between the banks of cylinders. This results in a minimising of the overall height of the housing making it possible to mount a supercharger unit directly on top of the housing and still allow clearance for the conventional bonnet or hood.
- The invention will now be described, by way of example only with reference to the accompanying drawings in which:
- FIG. 1 is a front view of part of a supercharged V-8 engine incorporating the heat exchange assembly of the present invention;
- FIG. 2 is a side view of the heat exchange assembly of this invention to which a supercharger and other ancillary components are mounted;
- FIG. 3 is a view similar to FIG. 1 in which the heat exchange of this invention has been sectioned;
- FIG. 4 is a plan view of part of the heat exchange assembly according to the present invention;
- FIG. 5 is a section view along the line5-5 of FIG. 4; and
- FIG. 6 is a perspective view of a heat exchange element used in the heat exchange assembly of the present invention.
- FIG. 1 generally states the layout of a supercharged V-8
engine 10 fitted with theheat exchange assembly 12 of the present invention. The V-8engine 10 is otherwise of substantially conventional type and will not be described in detail. Theengine 10 has cylinders schematically shown at 14 arranged in the well known V configuration.Cylinder heads 16 are provided withinlet ports 18 which open toward each other.Exhaust ports 20 are connected with exhaust pipes on the remote sides ofcylinder heads 16 in the conventional manner. Theheat exchange assembly 12 fits between the cylinder heads in the so-called valley of the engine and thesupercharger 24 is mounted to theheat exchange assembly 12. Thesupercharger 24 is substantially conventional and is driven in the known manner by a belt drive (not shown) viapulley 26. Athrottle body 28 controls emission of air to the supercharger in the conventional manner. Fuel supply to the engine is controlled byfuel injectors 30 andfuel supply lines 32 which also operate in the conventional manner. Thefuel injectors 30 are fitted to theheat exchange assembly 12 immediately adjacent the connection withinlet ports 18 incylinder head 16. - The
heat exchange assembly 12 is formed as a generallyrectangular housing 34 having atop 36,bottom 38 and opposedlongitudinal sides housing 34 to provide access to the interior of thehousing 34. Suitable fasteners such as bolts (not shown) and appropriate gaskets of conventional type can be provided to mount theheat exchange assembly 12 in place. In the form of the invention illustrated, thesupercharger 24 is mounted to theremovable top 36. Thetop 36 includes aninlet 44 through which pressurized airflow from thesupercharger 24 is directed to the interior of thehousing 34. The opposedlongitudinal sides openings 46 for communication with theinlet ports 18. This is achieved by connectingportions 48 and 50 along each side ofhousing 34 which includeducts 52 each extending through aflange 54 which is secured to theadjacent cylinder head 16. Thefuel injectors 30 described above are mounted so as to inject fuel into theducts 52. A V-shapedheat exchange element 56 is placed in thehousing 34. Theheat exchange element 56 is formed by two mutuallyinclined components top 36 andbottom 38 of thehousing 34. Thecomponents housing 34 to define aninlet region 62 adjacent thetop 36 of thehousing 34 andoutlet regions housing 34 and respectively adjacent theopenings 46 in thelongitudinal sides inlet 44 in thetop 36 ofhousing 34 to theopenings 46 must pass through theheat exchange element 56. Eachcomponent heat exchange element 56 has a heat exchange fluid path defined bytubing 68. The respective fluid flow paths extends between aninlet 70 and anoutlet 72 provided for each fluid flow path. Theinlets 70 and outlets 22 are connected to a cooling heat exchange element positioned at an appropriate place in the airflow of the vehicle. The cooled heat exchange fluid is directed to theinlets 70 so that the incoming heat exchange fluid goes to the central region of thehousing 34. The fluid flow passage subsequently directs the fluid through the fluid flow passage to adjacent thelongitudinal sides outlets 72. - In this way the cooled heat exchange fluid is directed to the central region of greatest airflow.
- It will be apparent that the
housing 34 of theheat exchange assembly 12 takes the place of the inlet manifold conventionally positioned between the cylinder heads of a V-configuration engine. Because theheat exchange element 56 is mounted within the space normally occupied by a conventional manifold a considerable height saving is achieved. This makes it possible to mount the supercharger unit directly on top of the housing and to still allow clearance for a conventional bonnet or hood. - The foregoing describes only one embodiment of the present invention and modifications can be made without departing from the scope of the invention. For example, although the heat exchange element described is a single unit it can be formed from two independent components each extending in the inclined manner described.
