Description

PRIORITY

This application claims the benefit of and priority to U.S. Provisional application, entitled “Water Neck For LS Engines,” filed on Oct. 28, 2015 and having application Ser. No. 62/247,648.

FIELD

The field of the present disclosure generally relates to engine cooling systems. More particularly, the field of the invention relates to an apparatus and a method for a water neck which is adapted to couple various radiator hoses with water pumps configured for use in performance automotive applications.

BACKGROUND

A water-cooled engine, such as an LS engine 104 shown in FIG. 1, typically comprises a cooling circuit comprising an internal water jacket, a thermostat valve, and a water pump 108 which receives water hoses extending from a radiator. A coolant typically comprising a mixture of water and an anti-freeze, such as ethylene glycol, and flowing within the cooling circuit conveys heat from the engine 104 to the radiator whereby excess heat is removed from the coolant so as to maintain operation of the engine within a suitable temperature range. The thermostat valve typically operates in conjunction with a bottom bypass of the water pump, whereby coolant bypasses the radiator and circulates within the internal water jacket when the temperature of the coolant is low. As the coolant approaches the suitable temperature range, however, the thermostat valve opens and allows the coolant to flow through the radiator by way of the water hoses. Once the coolant reaches the suitable temperature range, the radiator and the thermostat valve cooperate to maintain the operating temperature of the engine 104.
The water pump 108 typically is powered by the engine 104, often by way of a belted pulley assembly 112 or by way of a gear set connected between a crankshaft of the engine and the water pump 108. The water pump 108 generally comprises an impeller or a centrifugal pump that causes the coolant to flow through the engine, hoses, radiator, and other cooling circuit components. A water neck 116 typically provides an interface between the water pump 108 and a bottom hose extending from the radiator, and also houses the thermostat valve. As shown in FIG. 2, the water pump 108 comprises a coupling 120 configured to receive the thermostat valve and the water neck 116. The coupling 120 illustrated in FIG. 2 comprises a smooth surface 124 configured to receive a gasket and a similarly smooth surface of the water neck 116. A first threaded hole 128 and a second threaded hole 132 facilitate bolting the water neck 116 to the water pump 108 so as to establish a fluid-tight seal therebetween. A return conduit 136 is configured to receive a water hose whereby coolant heated by operation of the engine 104 is carried to the radiator for cooling.
In many performance automotive applications, it is desirable to install aftermarket radiator hoses, and thus it is advantageous to use a water neck which directs the aftermarket radiator hoses in a direction other than as provided by an original equipment manufacturer (OEM) of the water pump. An objective of the present disclosure, therefore, is to provide a water neck which is advantageously adapted to couple various radiator hoses with water pumps configured for use in performance automotive applications.

In general, the present disclosure describes an apparatus and a method for a water neck for use with a water pump whereby a coolant may be circulated from a radiator to an LS engine. The water neck comprises a conduit which includes an interior opening configured to receive the coolant from a water hose extending from the radiator. The conduit is comprised of an elongate, cylindrical section having a smooth exterior surface and a circumferential edge. The cylindrical section and the circumferential edge are configured to receive the water hose extending from the radiator. A base is configured to be coupled with the water pump, such that the coolant is conveyed from the water pump through the conduit. The base is configured to be installed onto a coupling of the water pump. The base and the coupling comprise smooth surfaces sharing substantially the same size and shape suitable for establishing a fluid-tight seal. A supportive section interconnects the conduit and the base, and is configured to orient a longitudinal axis of the conduit relative to the base so as to direct the conduit and the water hose away from the LS engine and a belted pulley assembly of the LS engine.
FIG. 3 illustrates a perspective view of an exemplary embodiment of a straight water neck 140, according to the present disclosure. The straight water neck 140 is configured to be coupled with the water pump 108 illustrated in FIG. 2, whereby coolant may be circulated from a radiator (not shown) to the LS engine 104, illustrated in FIG. 1, so as to maintain a suitable temperature range of the engine during operation. The straight water neck 140 preferably is comprised of a metal, such as, by way of non-limiting example, aluminum, any of various aluminum alloys, steel, and the like. It is contemplated, however, that the straight water neck 140 may be comprised of any rigid material that is sufficiently durable and temperature resistant to retain its configuration when coupled with the water pump 108 and during conveying heated coolant from the radiator to the LS engine 104.
The straight water neck 140 comprises a conduit 144 and a base 148 that are interconnected by way of a supportive section 152. In some embodiments, the conduit 144, the base 148, and the supportive section 152 may comprise sections of a single piece of material, such as billet aluminum, which is machined so as to produce the straight water neck 140 illustrated in FIG. 3. In some embodiments, the conduit 144, the base 148, and the supportive section 152 may comprise sections of a single piece of material which has been molded so as to produce the straight water neck 140. In some embodiments, the conduit 144, the base 148, and the supportive section 152 may comprise individual components that are assembled together so as to produce the straight water neck 140. In some embodiments, the conduit 144, the base 148, and the supportive section 152 are welded together so as to produce the straight water neck 140, as illustrated in FIG. 3. In still some embodiments, the conduit 144, the base 148, and the supportive section 152 are individual components each comprised of machined billet aluminum and then welded together so as to form the straight water neck 140. Those skilled in the art will recognize that the straight water neck 140 may be produced by way of various other suitable materials and processes without deviating beyond the spirit and scope of the present disclosure.
The conduit 144 generally is comprised of an elongate, cylindrical section 156 having a smooth exterior surface, an interior opening 160, and a circumferential edge 164. The cylindrical section 156 and the circumferential edge 164 are configured to receive a water hose extending from the radiator. The cylindrical section 156 generally has an outer diameter sized such that the conduit 144 may be slidably inserted into an interior opening of the water hose. It is contemplated that any of a wide variety of mechanical fasteners may be used to fasten the water hose onto the conduit 144 so as to form a fluid-tight seal between the straight water neck 140 and the water hose. Preferably, the circumferential edge 164 comprises at least one structure configured to cooperate with the water hose and the mechanical fastener so as to retain the fluid-tight seal between water hose and the conduit 144 during operation of the engine 104. For example, the circumferential edge 164 may comprise any of a variety of ridges, lips, or raised portions so as to optimally engage the water hose. It should be understood that the specific configuration of the conduit 144 depends upon the particular configuration of the water hose being utilized, and thus a wide variety of specific configurations may be incorporated into the conduit 144 without straying beyond the scope of the present disclosure.
As mentioned above, the supportive section 152 interconnects the conduit 144 with the base 148. The supportive section 152 serves as a structural foundation for the conduit 144, and orients a longitudinal axis 146 of the conduit 144 relative to a plane of the base 148 so as to direct the conduit 144, and thus the water hose, away from the LS engine 104 and the belted pulley assembly 112. In the embodiment illustrated in FIG. 3, the longitudinal axis 146 is substantially normal to the plane of the base 148. It is contemplated, however, that the supportive section 152 may be configured so as to orient the conduit 144 with one or more angles relative to the base 148, as described herein.
As will be appreciated, the interior opening 160 extends through the conduit 144, the supportive section 152, and the base 148 such that coolant received into the base from the water pump is conveyed through the water neck 140 to the water hose. As such, the base 148 is configured to be installed onto the water pump 108 as illustrated in FIG. 1. The base 148 generally comprises a smooth surface (not shown) having a size and a shape which matches the size and shape of the smooth surface 124, illustrated in FIG. 2. The smooth surface of the base 148 is suitable for establishing a fluid-tight seal with the smooth surface 124 of the water pump 108. As will be recognized, a gasket may be disposed between the smooth surface 124 and the smooth surface of the base 148 so as to form the fluid-tight seal. In some embodiments, the thermostat valve may be coupled with the gasket between the water pump 108 and the base 148. In some embodiments, the smooth surface of the base 148 may further comprise a circumferential countersink which is disposed around the opening 160 so as to provide clearance for the thermostat valve when the base 148 is placed into contact with the gasket and the smooth surface 124.
As shown in FIG. 3, the base 148 comprises a first hole 168 and a second hole 172 disposed on opposite sides of the supportive section 152 so as to respectively align with the first and second threaded holes 128, 132 of the water pump 108. The first and second holes 168, 172 are configured to receive bolts 176, as shown in FIG. 1. The bolts 176 each comprises a size, a length, and a threading so as to suitably engage with the first and second threaded holes 128, 132. It is contemplated that the first and second holes 168, 172 comprise a diameter which is larger than a diameter of the bolts 176 so as to allow passage of the bolts through the base 148 such that the bolts 176 may be threadably engaged with the first and second threaded holes 128. 132. Further, it is envisioned that the above-described gasket comprises holes that are similarly sized to, and aligned with, the first and second holes 168, 172 so as to prevent the gasket from obstructing the bolts 176 being engaged with the threaded holes 128, 132.
As will be appreciated, the straight water neck 140 may be installed onto the water pump 108 with the gasket disposed therebetween. In some embodiments, the gasket may be treated with any one of various gasket sealants so as to further prevent coolant from leaking out of the coupling between the straight water neck 140 and the water pump 108. During installation of the straight water neck 140, a thin layer of gasket sealant may be applied to the smooth surface of the base 148. The gasket may then be applied to the smooth surface of the base 148 such that the holes in the gasket are aligned with the first and second holes 168, 172. While the thin layer of gasket sealant holds the gasket fixed to the base 148, a thin layer of gasket sealant may be applied to the remaining exposed surface of the gasket. Further, in those embodiments wherein the base 148 includes the circumferential countersink, the thermostat valve may be positioned between the base 148 and the gasket. In other embodiments, the thermostat valve may be installed into the coupling 120. The straight water neck 140 with the gasket and sealant may then be pressed onto the smooth surface 124 of the water pump 108 such that the first and second holes 168, 172 are respectively aligned with the first and second threaded holes 128, 132. While holding the straight water neck 140 in position, the bolts 176 may be inserted into the first and second holes 168, 172 and then threadably engaged with the first and second threaded holes 128, 132. Installation of the straight water neck 140 may be completed by applying a manufacturer recommended degree of torque to each of the bolts 176.
FIG. 4 illustrates a perspective view of an exemplary embodiment of an angled water neck 180 which may be coupled with the water pump 108, whereby coolant may be circulated from the radiator to the LS engine 104, as described herein. The angled water neck 180 is substantially similar to the straight water neck 140 illustrated in FIG. 3, with the exception that the angled water neck 180 comprises an angled supportive section 184 in lieu of the supportive section 152. As will be appreciated, the angled supportive section 184 serves to direct the conduit 144, and thus the water hose, away from the LS engine 104 and the belted pulley assembly 112. The angled supportive section 184 is configured to orient a longitudinal axis 188 of the conduit 144 at a polar angle θ with respect to a line A-A which is normal to the base 148, and an azimuthal angle φ relative to a straight line B-B extending through the first and second holes 168, 172. In the embodiment illustrated in FIG. 4, the polar angle of the longitudinal axis 188 is substantially 90 degrees, and the azimuthal angle is substantially 45 degrees. It will be recognized, however, that the polar and azimuthal angles of the conduit 144 depend upon a specific automotive application, as well as a particular engine for which the water neck 180 is intended to be installed. It should be understood, therefore, that the polar and azimuthal angles of the conduit 144 are not to be limited to the values described herein, but rather the polar angle may range from substantially 0 degrees to substantially 90 degrees, and the azimuthal angle may range from substantially 0 degrees to substantially 180 degrees, without limitation, so as accommodate at least a majority of the various automotive applications for which the angled water neck 180 may be installed.
While the invention has been described in terms of particular variations and illustrative figures, those of ordinary skill in the art will recognize that the invention is not limited to the variations or figures described. In addition, where methods and steps described above indicate certain events occurring in certain order, those of ordinary skill in the art will recognize that the ordering of certain steps may be Modified and that such modifications are in accordance with the variations of the invention. Additionally, certain of the steps may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above. To the extent there are variations of the invention, which are within the spirit of the disclosure or equivalent to the inventions found in the claims, it is the intent that this patent will cover those variations as well. Therefore, the present disclosure is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims.
