Abstract
A fluid containment unit for automotive applications that is capable of being easily enlarged, changed, modified and configured.
Description
FIELD

The present invention is related to automotive fluid containment units, and more particularly, to modular automotive fluid containment units.


BACKGROUND

Fluid tanks are used in automobiles to contain fluids in a number of applications and configurations. These applications include, but are not limited to, coolant containment tanks, brake hydraulic reservoirs, pneumatic gas storage tanks, and power steering fluid reservoirs.


For example, the cooling system is one of the most important systems in the vehicle because it keeps the engine at a right temperature, allowing it to work efficiently. Since the engine takes charge of burning the air and fuel mixture, it produces large amount of heat that makes the parts so hot and vulnerable to damage. The cooling system dissipates the heat from the engine and its parts through the coolant. This coolant absorbs the heat as it circulates around the engine and goes to the radiator where it transfers the heat to the cool air.


A coolant is a mixture of water and anti-freeze, which is a chemical solution, usually ethylene glycol and anticorrosion chemicals. When heated the coolant expands. Thus, most cooling systems have an expansion tank that provides storage space for the heated coolant. The expansion tank is usually plastic and is connected to the radiator through the overflow tube. It is also called a radiator overflow tank, coolant-recovery tank, coolant reservoir, or simply overflow tank or canister. These names imply its function, which is to hold the overflowing coolant that absorbed the heat from the engine.


Not all vehicles have a radiator overflow tank; however, this part is helpful in the cooling system. Without it, the expanded or heated coolant could flow out of the overflow tube and eventually, out of the vehicle and out onto the street. The expansion tank or radiator overflow tank provides additional volume for the coolant to occupy after it absorbed the heat from the engine. Also, the radiator overflow tank removes air bubbles from the coolant, thus, allowing it to absorb heat more efficiently and to prevent air bubble blockage. Furthermore, when a vehicle has an overflow tank containing coolant, the radiator is always full. Only the proper amount of the coolant goes to the radiator for cooling and this goes back to the engine to absorb heat once again. When the engine cools, vacuum is created in the cooling system since it is a closed system. This causes the coolant in the radiator overflow tank to be sucked back into the cooling system.


One problem with stock overflow tanks is that they are made for a specific model and make of vehicle. Further, the overflow tanks themselves are not capable of being enlarged and larger tanks may not fit within the space constraints of the vehicle.


These issues are also shared by the other applications for fluid containment units. Therefore it is highly desirable to have a fluid containment unit that is capable of being easily enlarged, changed, modified and configured.

DETAILED DESCRIPTION

References will now be made to embodiments illustrated in the drawings and specific language which will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated devices, as such further applications of the principles of the invention as illustrated therein as being contemplated as would normally occur to one skilled in the art to which the invention relates.


Embodiments in accordance with the present invention relate to providing modular fluid storage units. The modular fluid storage units comprise one or more modular members that provide for configurable and customizable fluid volumes suitable for a particular purpose. Further, the modular fluid storage units provide means for coupling to fluid systems suitable for a particular purpose.



FIG. 1 is a side cross-section view of a modular fluid containment unit 2 in accordance with an embodiment of the present invention. The modular fluid containment unit 2 comprises one or more modular members 10, a bottom coupler 12 and a cap 11. Each modular member 10 is a cylinder or tube having a threaded first end 16 and a threaded second end 15. The threaded first end 16 is adapted for threadable engagement with a threaded second end 15 of another modular member 10. The threaded first end 16 is also adapted for threadable engagement with the cap 11. The threaded second end is adapted for threaded engagement with the bottom coupler 12.


The bottom coupler 12 comprises a threaded first end 14 and a hose coupling 13. The threaded first end 14 is adapted for threadable engagement with a threaded second end 15 of a modular member 10. The hose coupling 13 is adapted to couple with a hose from the vehicle cooling system (not shown).


The modular member 10 includes a bore 18 that defines an inner volume suitable for containing fluid. The modular member 10 has a predetermined length and the bore 18 has a predetermined diameter suitable for a particular purpose. The volume within the modular member for containing fluid is increased or decreased by increasing or decreasing, respectively, either or both of the length or diameter.


The fluid volume of the modular fluid containment unit 2 can be increased by adding additional modular members 10. It is this modular aspect of the present invention that allows the customization of the volume of the modular fluid containment unit 2 by simply adding one or more additional modular members 10.


Referring again to FIG. 1, the modular fluid containment unit 2 provides threaded coupling between the modular members 10, the bottom coupler 12 and the cap 11. It is appreciated that any suitable coupling means, or combinations, may be used suitable for a particular purpose. By example only, but not limited therein, the coupling can be a slip-fit with o-ring, threaded with o-ring seal, compression fitting, among many others.



FIG. 2 is an exploded view of a modular fluid containment unit 4 in accordance with an embodiment of the present invention.

The o-ring 40 seals the first end 116 to the coupling portion 57, such that the modular fluid containment unit 4 contains the fluid. The o-ring 40 in combination with the coupling portion 57 provides a friction fit such that the elements may be removably coupled. It is appreciated that other methods of removable coupling may be used, such as, but not limited to, threads and locking collars as is well known in the art.



FIGS. 5A and 5B are perspective and side cross-sectional views of the bottom coupler 12, in accordance with an embodiment of the present invention. The bottom coupler 12 has a first end 60 and a second end 62. The first end 60 includes a mouth 54 suitable for receiving the coupling portion 51 of a modular member 110. The coupling portion 51 and the mouth 54 are adapted for cooperative engagement therebetween.


The coupling portion 51 comprises a suitable diameter such that it may be slidably received within the mouth 54. The o-ring 44 seals the second end 115 to the mouth 54, such that the modular fluid containment unit 4 contains the fluid.
