[QUOTE="cChrisM, post: 9354510, member: 80545"] Thanks for your kind comment, but keep in mind the following: Radiator Rows ....the Myth There is a widespread misconception of the value of multiple rows in an automotive radiator. It is first necessary to understand how a radiator cools an engine. The basic law of physics "cold absorbs heat" applies. The hot coolant from the engine flows into the inlet tank of the radiator and flows through the tubes to the outlet tank. the heat of the coolant is absorbed by the fins which are colder than the coolant. In turn, the colder air passing through the fins absorbs the heat from the fins. The fluid, now cooled flows back into the engine and absorbs the heat from the engine and goes back through the radiator to be cooled The tubes in a radiator do not in themselves lower the temperature of the coolant. The tubes only serve to bring the coolant to the fins which dissipate the heat into the air passing through the radiator core. The cooling capacity is determined only by the total surface area of the fins in contact with the air passing through the core. The thicker the core, the higher the cooling capacity of the radiator. The maximum size of brass tubes is 5/8" because of the physical properties of brass. If the tubes were made larger, they would not be able to withstand the pressure and would "balloon" and eventually rupture. The number of rows is determined by the core thickness. Cramming extra rows into a particular core thickness has no advantage and actually decreases efficiency as the surface area of the fins would be reduced. Aluminum radiators are now being used in 99% of today’s new vehicles. The copper/brass radiator is on the verge of extinction. Because of the strength of aluminum, larger and wider tubes are now possible, allowing a higher volume of coolant to come in contact with the fins. A 1 inch aluminum tube can carry more coolant than two 5/8 inch brass tubes. Another property of aluminum, because of its strength over copper, is that the fins can be thinner and more fins can fit in a given space. In conclusion, when determining how efficient a radiator is, only be guided by core thickness and fin density (fins per square inch). . [/QUOTE]
