## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of priority to U.S. Provisional Application No. 61/417,607 filed Nov. 29, 2010, the contents of which are incorporated herein by reference.


BACKGROUND OF THE INVENTION
The present invention generally relates to a spin-on oil filter adapter with increased cooling capability for internal combustion engines. More particularly, the present invention relates to a spin-on oil filter adapter having integrated cooling fins.
Internal combustion engines circulate oil through the engine to reduce friction between moving parts while the engine is in operation. During the circulation process, the oil accumulates debris and heats up from the heat dissipated from the engine. Oil filters are currently used to filter the lubricated oil. Oil filters are generally placed on the engine block. In order to add engine oil cooling capability to an engine an oil cooler is generally installed and this requires an spin-on adapter to be installed on the block to facilitate the hoses to and from the cooler. This requires the oil filter to be mounted at a distance from the engine.
As can be seen, there is a need for a device that provides additional cooling capability to the engines oil system.

In one aspect of the present invention, a spin-on adapter includes a unitary piece main body having edges, a base attached to the main body, a step between the main body and the base, a first orifice and a second orifice extending throughout the main body, the step, and the base, a plurality of cooling fins protruding from the edges of the main body, the plurality of fins are integrated to the unitary piece main body, and the adapter is adapted to be secured to a vehicle engine.
In another aspect of the present invention, a spin-on adapter for a remote oil filter including a main body having edges, a base attached to the main body, a step formed between the main body and the base, a first orifice and a second orifice extending throughout the main body, the step, and the base, a plurality of cooling fins integrated to and protruding from the edges of the main body, the base and the step include a perimeter having a wavy shape including peaks and valleys, and the fins project away from the main body until reaching the peaks of the base.

DETAILED DESCRIPTION OF THE INVENTION
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Various inventive features are described below that can each be used independently of one another or in combination with other features.
Broadly, embodiments of the present invention generally provide a spin-on oil filter adapter to provide additional cooling capability to an engine lubrication system.
FIG. 12 shows a diagram employing an adapter 10 for a remote oil filter 15 according to an exemplary embodiment of the present invention. The adapter 10 may be operatively connected to a threaded nipple 29 on an engine 17. An O-ring 19 may be placed between the engine 17 and the adapter 10 to maintain a fluid-tight seal. Oil coming out from the engine 17 may pass through a first orifice 16 (shown on FIGS. 1-4) on the adapter 10. The oil may be transported to an oil cooler 23 by an inlet oil line 22a. The oil may circulate through the oil cooler 23 to cool the oil. The oil may be transported from the oil cooler 23 to a remote oil filter 15 by a hose 27. The oil may be transported from the remote oil filter 15 to a second orifice 14 (shown on FIGS. 1-4) on the adapter 10 by using an outlet oil line 22b. 
Referring now to FIGS. 1-5, the adapter 10 may include a main body 11 including edges 13. The main body 11 may be a spin-on type body. The main body 11 may be a single piece body. The main body 11 may be made of a heat resistant material, for example, metal. The main body 11 may be made by metal casting, stamping, forging, molding, or machining. The size of the main body 11 may depend on the type of engine 17 and the capability of the remote oil filter 15.
A base 24 may be secured to the main body 11. The shape of the base 24 may depend on the shape of the main body 11. The shape of the base 24 may be, for example, round. A threaded circular groove 20 may be partially recessed in an outer surface 25 of the base 24. The circular groove 20 may be adapted to receive the O-ring 19 (shown on FIG. 12) to maintain a fluid-tight seal between the adapter 10 and the engine 17. A gap 37 may be formed on the inside of the base 24. The gap 37 may be formed underneath of the step 27. The gap 37 may provide the base 24 with additional space for the oil to move.
A step 27 may be formed between the main body 11 and the base 24 and framed between adjacent fins 12. The step 27 may include a perimeter 39 having a wavy pattern. The wavy pattern of the perimeter 39 may include peaks 39A and valleys 39B. The step 27 may provide the adapter 10 with additional surface area for the cooling process.
The first orifice 16 and the second orifice 14 may extend throughout the main body 11, the step 27, and the base 24. The first orifice 16 and the second orifice 14 may include internal threads 30, 28 respectively. The size of the first orifice 16 and the second orifice 14 may depend on the size of the inlet oil line 22a and the outlet oil line 22b. 
A sleeve 18 may be connected to the first orifice 16. The sleeve 18 may include threads 32 to facilitate the connection with the threads 30 of the first orifice 16.
A plurality of cooling fins 12 may be integrated into the edges 13 of the main body 11. The cooling fins 12 may increase the surface area of the adapter 10 providing the remote oil filter 15 (shown on FIG. 12) with additional cooling capabilities. The cooling fins 12 may protrude radially from the edges 13 of the main body 11 and extend in a circular pattern from the edges 13 of the main body 11. The cooling fins 12 may be built into the main body 11 during the manufacturing process by stamping, molding, forging, casting or machining.
The base 24 may include a perimeter 31 having a wavy pattern. The wavy pattern of the perimeter 31 may include peaks 31B at distal ends of the fins 12 and valleys 31A in between the fins 12. The wavy pattern of the perimeter 31 may help create a larger surface area for the cooling fins 12 to rest on.
Referring now to FIGS. 6-8, the main body 11 may include an inner section 38. The sleeve 18 may be attached to the inner section 38 of the main body 11. The sleeve 18 may have a first end 18A adapted to be secured to the threaded nipple 29 (shown on FIG. 12) to secure the adapter 10 to the engine 17. A second end 18B of the sleeve 18 may be connected to the first orifice 16.
FIGS. 9-11 show an adapter 34 for a remote oil filter, for example, the remote oil filter 15 shown in FIG. 12, according to another exemplary embodiment of the present invention. In this embodiment, the adapter 34 may be the same as the embodiment shown in FIGS. 1-8 except that the adapter 34 may include a plurality of cooling fins 36 protruding circumferentially from a main body 26. The cooling fins 36 may be parallel to each other around the main body 26, planar from the base 24.
The adapter 10, 34 may add additional cooling capability to the oil filtering system by increasing the surface area, which in turn increases the heat dissipation through heat sink. The heat may be transferred from a solid material (the adapter 10, 34) to another medium, such as air. The hot engine oil may be in contact with the adapter 10, 34 as the engine 17 pumps the oil through it. Because of the larger surface area of the adapter 10, 34, greater heat transfer is achieved, and greater cooling capability may be obtained.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
