Complementary ribs for added structural strength

A radiator tank for a radiator comprising:

• a plurality of first reinforcement ribs spaced apart along a first sidewall;
• a plurality of second reinforcement ribs spaced apart along a second sidewall;
• a plurality of third reinforcement ribs spaced apart along an upper portion that extends from the first sidewall to the second sidewall;
• wherein:
• the first reinforcement ribs and the second reinforcement ribs are on opposing inner surfaces of the first sidewall and the second sidewall respectively opposite to smooth outer surfaces of the first sidewall and the second sidewall, and the third reinforcement ribs are on an outer surface of the upper surface that is opposite to a smooth inner surface of the upper surface;
• the first and the second reinforcement ribs terminate prior to the upper portion, and the third reinforcement ribs terminate prior to both the first sidewall and the second sidewall;
• the plurality of first reinforcement ribs do not directly contact the plurality of second reinforcement ribs;
• the third reinforcement ribs extend from a first area opposite to where the first reinforcement ribs terminate prior to reaching the upper portion, and the third reinforcement ribs extend to a second area opposite to where the second reinforcement ribs terminate prior to reaching the upper portion such that the third reinforcement ribs do not generally overlap with either the first reinforcement ribs or the second reinforcement ribs;
• and
• the radiator tank is formed from a single die without additional die slides.

A radiator tank for a radiator comprising:

• a first sidewall including a first inner surface, the first sidewall is configured to couple with a radiator plate of the radiator;
• a second sidewall including a second inner surface, the second sidewall is configured to couple with the radiator plate, the second inner surface is opposite to the first inner surface;
• an upper portion extending between the first sidewall and the second sidewall, the upper portion including an outer surface;
• a plurality of spaced apart first reinforcement ribs extending along the first inner surface of the first sidewall generally perpendicular to the radiator plate and opposite to a first outer surface that is smooth, the first reinforcement ribs terminate prior to reaching the upper portion;
• a plurality of spaced apart second reinforcement ribs extending along the second inner surface of the second sidewall generally perpendicular to the radiator plate and opposite to a second outer surface that is smooth, the second reinforcement ribs terminate prior to reaching the upper portion;
• and
• a plurality of third reinforcement ribs extending from the outer surface of the upper portion opposite to an inner surface of the upper portion that is smooth, the third reinforcement ribs terminate prior to reaching the first sidewall and the second sidewall;
• wherein:
• the plurality of spaced apart first reinforcement ribs do not directly contact the plurality of spaced apart second reinforcement ribs;
• the plurality of third reinforcement ribs extend from a first area opposite to where the plurality of first reinforcement ribs terminate prior to reaching the upper portion, and the plurality of third reinforcement ribs extend to a second area opposite to where the plurality of second reinforcement ribs terminate prior to reaching the upper portion such that the plurality of third reinforcement ribs do not generally overlap with either the plurality of first reinforcement ribs or the plurality of second reinforcement ribs;
• and
• the radiator tank is formed from a single die without additional die slides.
