Radiator Analysis - Tech Knowledge

Does size really matter? A larger radiator allows the core to dissipate heat more effectively, but the tube-and-fin design plays just as important a role in the radiator's ability to keep your engine cool. Mike Small of Koyo Cooling Systems explains that as the water is split into multiple tubes, the heat dissipating "load" is split, similar to an 18-wheeler splitting the cargo load over 18 tires rather than four. Radiators using decreased tube pitch (distance from one tube to another) will lead to a denser-capacity core that increases cooling efficiency, but too dense a core will decrease air travel through the fins, decreasing cooling efficiency. The ideal radiator will have optimized fin-density for maximum heat dissipation. "The 'trick' is getting the right balance of fins and tubes based on all the variables," said Small.
