Problem
The materials used in some types of finned products, such as vacuum brazed block, or ribbon wound L-fin tubes, are often thin gauge and very soft due to the necessity of the manufacturing process. This leaves a product very susceptible to damage by impact, handling or cleaning. The construction of such products may also render the tubes on the face of the block to be exposed to potential damage from flying debris penetrating the tubes. “Be very careful not to use too much direct air pressure on the air-fins or they may be damaged”… ”Be careful with high pressure spray not to damage or flatten air-fins”… ”Straighten air-fins after cleaning with a small screwdriver being careful not to puncture radiator tubes” These statements have been extracted from the Q&A pages of well known brazed radiator manufacturer's web sites and clearly demonstrate one of the major weaknesses of soft-fin core technologies. |
Solution
Durability is the cornerstone of the Elfin design. Whatever we achieve with regard to performance, weight and cost, Elfin finned products will always be designed for enhanced durability. The many other inherent weaknesses associated with brazed cores and ribbon wound tubes have been specifically designed out of Elfin finned products, resulting in far greater reliability and longevity. Even greater robustness can be achieved through the optional use of Titanium or Stainless Steel tubes with interspersed Titanium or Stainless Steel fins - such configurations have been proven to withstand a shotgun blast, the equivalent of debris impacting with the cooler core at a speed of at least 800mph. |
