Dual-pass radiator against the single-pass circuit design

Theoretically and logically advantages of radiators with the circuit design two-through passage in comparison with single-pass designs are conclusive if to make the corner-stone of their chilling ability.

The dual-pass radiator Коуо represented in drawing, is executed on production engineering N-FLO. Which means two compulsory veerings of a fluid stream on half of its way through the case. Such traffic diagramme reminding the letter "N", divides the shell into separate compartments and allows to improve efficiency of the heat abstraction at the expense of triple accretion of a time of a finding of antifreeze in a radiator.

Representative Kouo explains Scott Oshiro: "Dual-pass radiators N-FLO have been developed specially under certain conditions in which cooling was a problem, for example, for drift-cars". In similar competitions use of the circuit design two-through passage allows to keep a cooling system effectiveness, even when air runs on a radiator frame with good speed a smaller part of race.

If excessive heating problems are not peculiar to the car, the majority of manufacturers recommend in radiators, both with descending, and with a cooling fluid cross flux to use the single-pass circuit design in which the maximum temperature is brought to all tubes simultaneously. Dual-pass radiators work effectively and at high speeds of a running air flow, but create thus the big loadings in a motor engine water pump, and slow passage of a liquid calls excessive growth of a system pressure of cooling.
