## Background
FIELD
The present disclosure relates to structural reinforcement ribs, such as ribs of a radiator tank, for added structural strength.
BACKGROUND
This section provides background information related to the present disclosure which is not necessarily prior art.
A radiator tank is repeatedly subject to large changes in pressure, which results in repeated expansion and contraction of the tank. This repeated expansion and contraction can damage the radiator tank, such as at an interface between the radiator tank and a radiator core. Typical radiator tanks are without structural reinforcements sufficient to reduce stress on the radiator tank caused by pressure changes therein, and do not include structural reinforcements that can be implemented in an efficient and cost-effective manner.

DETAILED DESCRIPTION
Example embodiments will now be described more fully with reference to the accompanying drawings.
With initial reference to FIG. 1, a radiator tank according to the present teachings is illustrated at reference 10. The radiator tank 10 is coupled to a radiator plate 12. The radiator tank 10 generally includes a first sidewall 14, a second sidewall 16, and an upper portion 18 that extends from the first sidewall 14 to the second sidewall 16. The first sidewall 14, the second sidewall 16, the upper portion 18, and the radiator plate 12 generally define an interior cavity 20 of the radiator tank 10. The interior cavity 20 is configured to house, for example, radiator coolant.
With continued reference to FIG. 1 and additional reference to FIGS. 2 and 3, the first sidewall 14 generally includes a first outer surface 22 and a first inner surface 24, which is opposite to the first outer surface 22. The first outer surface 22 and the first inner surface 24 extend generally parallel to one another along a length of the radiator tank 10. Extending from the first sidewall 14 is a first flange 26, which also extends generally along the length of the radiator tank 10. The first flange 26 can be received within a first receptacle 28 of the radiator plate 12, and secured within the first receptacle 28 to mount the radiator tank 10 to the radiator plate 12.
The first sidewall 14 further includes a plurality of first reinforcement ribs 30. The first reinforcement ribs 30 extend generally perpendicular to the radiator plate 12 and are spaced apart along the first sidewall 14. The first reinforcement ribs 30 extend from an area proximate to the first flange 26 and terminate prior to reaching the upper portion 18. As illustrated, the first reinforcement ribs 30 are protrusions extending from the first inner surface 24. Alternatively, the first reinforcement ribs 30 may be provided at any other suitable location on the first sidewall 14. For example, the first reinforcement ribs 30 may be provided on the first outer surface 22. The first reinforcement ribs 30 may be any suitable reinforcement member that enhances the structural rigidity of the first sidewall 14. Thus, one or more of the first reinforcement ribs 30 need not take the form of a rib. The first reinforcement ribs 30 can be unitarily molded with the radiator tank 10, or can be separate components that are attached to the first sidewall 14 in any suitable manner, such as by welding.
The second sidewall 16 generally includes a second outer surface 32 and a second inner surface 34. The second outer surface 32 is opposite to the second inner surface 34. The second outer and inner surfaces 32 and 34 extend generally parallel to one another along the length of the radiator tank 10. The second inner surface 34 faces the first inner surface 24. Extending from the second sidewall 16 is a second flange 36. The second flange 36 extends along a length of the second sidewall 16 and is configured to be received and secured within a second receptacle 38 of the radiator plate 12 in order to mount the radiator tank 10 to the radiator plate 12.
The second sidewall 16 further includes second reinforcement ribs 40. The second reinforcement ribs 40 are similar to the first reinforcement ribs 30. The second reinforcement ribs 40 extend generally perpendicular to the radiator plate 12 and are spaced apart long the second sidewall 16. The second reinforcement ribs 40 extend from an area proximate to the second flange 36 and terminate prior to reaching the upper portion 18. As illustrated, the second reinforcement ribs 40 are protrusions extending from the second inner surface 34. Alternatively, the second reinforcement ribs 40 may be provided at any other suitable location on the second sidewall 16. For example, the second reinforcement ribs 40 may be provided on the second outer surface 32. The second reinforcement ribs 40 may be any suitable reinforcement member that enhances the structural rigidity of the second sidewall 16. Thus, one or more of the second reinforcement ribs 40 need not take the form of a rib. The second reinforcement ribs 40 can be unitarily molded with the radiator tank 10, or can be separate components that are attached to the second sidewall 16 in any suitable manner, such as by welding.
The second reinforcement ribs 40 can be arranged such that most or all of the second reinforcement ribs 40 are aligned with the first reinforcement ribs 30. Alternatively, the first reinforcement ribs 30 and the second reinforcement ribs 40 can be staggered with respect to one another such that the second reinforcement ribs 40 are not opposite to the first reinforcement ribs 30, but rather opposite to spaces between the first reinforcement ribs 30 and thus interleaved with the first reinforcement ribs 30.
The upper portion 18 includes a third outer surface 42 and a third inner surface 44, which is generally opposite to the third outer surface 42. The third outer surface 42 and the third inner surface 44 are both generally curved and generally extend along a length of the radiator tank 10. The third inner surface 44 is opposite to the radiator plate 12 and is generally concave with respect to the radiator plate 12. The third outer surface 42 is generally convex with respect to the radiator plate 12.
The upper portion 18 further includes a plurality of third reinforcement ribs 46 extending from the third outer surface 42. The third reinforcement ribs 46 are generally spaced apart along the length of the upper portion 18, and each extend generally from the first sidewall 14 to the second sidewall 16. The third reinforcement ribs 46 terminate generally at, or prior to reaching, each of the first sidewall 14 and the second sidewall 16. The third reinforcement ribs 46 generally extend from a point opposite to where the first reinforcement ribs 30 terminate prior to reaching the upper portion 18, to a point opposite to where the second reinforcement ribs 40 terminate prior to reaching the upper portion 18.
The third reinforcement ribs 46 can alternatively be arranged on the third inner surface 44. When the third reinforcement ribs 46 are on the third inner surface 44, the first and the second reinforcement ribs 30 and 40 will be arranged on the first outer surface 22 and the second outer surface 32 respectively. The third reinforcement ribs 46 can be any suitable reinforcement member that enhances the structural rigidity of the upper portion 18. Thus, one or more of the third reinforcement ribs 46 need not take the form of a rib. The third reinforcement ribs 46 can be unitarily molded with the radiator tank 10, or can be separate components that are attached to the upper portion 18 in any suitable manner, such as by welding.
As illustrated in FIGS. 1-3, the third reinforcement ribs 46 are generally aligned with each of the first reinforcement ribs 30 and the second reinforcement ribs 40. Therefore, each one of the first reinforcement ribs 30, the second reinforcement ribs 40, and the third reinforcement ribs 46, combine to generally provide a single reinforcement rib extending about the radiator tank 10 from about the first flange 26 to about the second flange 36. With additional reference to FIG. 4, the third reinforcement ribs 46 may alternatively be arranged offset with respect to each of the first reinforcement ribs 30 and the second reinforcement ribs 40. Arranging the first, second and, the third reinforcement ribs 30, 40, and 46 in either manner enhances the structural strength of the radiator tank 10. Therefore, the radiator tank 10 can withstand large pressure changes within the interior cavity 20 without being damaged, particularly where the radiator tank 10 connects to the radiator plate 12. Arranging the first, second, and the third reinforcement ribs 30, 40, and 46 in either manner permits the radiator tank 10 to be manufactured using a single die without additional slides, which provides for a more efficient and less costly manufacturing process.
The radiator tank 10 further defines a connection port 50 and a vehicle mount 52. The connection port 50 is generally cylindrical and extends from the first outer surface 22 of the first sidewall 14. The connection port 50 is configured to direct coolant to and from the radiator tank 10. The vehicle mount 52 extends from the upper portion 18 of the third outer surface 42.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
