   ElfinBlock Finned Cores      
ElfinBlock is a plate-fin type extended-surface core design with multiple tubes bonded to multiple fins, forming a strong and durable block-matrix. ElfinBlock is manufactured using state-of-the-art CNC-controlled machinery that results in a high-quality, yet competitively priced finished product.

ElfinBlock is unique in many ways but one of the most important, as far as thermal performance and flexibility are concerned, is the ability to incorporate internal extended-surfaces within the base tube itself.

Another unique capability is the use of exotic materials, for both the tubes and fins, such as Stainless Steel, Titanium, Hastelloy, Zirconium etc to provide enhanced solutions to specific problems. This means that conventional coolers that are not able to withstand an aggressive environment and fail due to corrosion, erosion, stress fracture etc., can be redesigned and remanufactured using resistant materials. However, the main advantage of ElfinBlock is that the same construction method is employed regardless of the materials used and therefore can be achieved with minimal additional expense.

This material flexibility also allows hard materials to be used and the precision by which they are placed facilitates the use of advanced fin enhancement technology to be incorporated. ElfinBlock fins are both flat and consistent. With CNC fin placement to within a few microns, stacked rows align better to reduce pressure drop.

These attributes combine to reduce performance-degrading fouling issues. The ability to use harder tempered fin materials also means that should fouling occur, the fined core can be pressure washed without causing damage and further performance degradation.

ElfinBlock Fin Press Tool
No other product of this type can boast such a broad range of attributes.

Physical Characteristics:-

Highly flexible and rugged construction
Bespoke fin and tube profiles
High vibration resistance
High impact resistance
High temperature resistance
Wide range of materials available
Inter-locking fin construction
Integral flow enhancement techniques
From 1 to 36 fins per inch (40 to 1500 fpm)
Unlimited tube wall thickness
Integral tube supports

Performance Characteristics:-

Enhanced tube-to-fin heat transfer coefficients
Extremely low pressure drop
High thermal performance

How are these benefits achieved?

Fins are precision manufactured to exacting tolerances, ensuring a good mechanical bond with the base tube(s) and a streamlined air-on profile
Fins have an integral collar which is designed to interlock firmly with the adjacent fins
The manufacturing process allows for harder fin materials than with conventional ribbon-wound tubes, imparting high strength and impact resistance
Fins can incorporate airflow enhancement techniques with a low pressure-drop overhead
Tubes can incorporate internal flow turbulators and/or extended surfaces

So what is possible?

The Elfin design is inherently flexible and as such, can be configured to a limitless number of advanced derivatives of the basic design. Solutions now exist to inherent heat exchanger problems, with the adaptation of this new technology.
