| ElfinBlock Technology | ||
| ElfinBlock, in it's simplest form, is a multi-tube derivative of the standard Elfin design, but with multiple tubes bonded to each fin to form a block-matrix. ElfinBlock is manufactured using state-of-the-art CNC-controlled ElfinMaster machinery which swages fins on to tubes with an interference fit 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 solutions to specific problems The manufacturing method allows hard materials to be used and the precision by which they are placed facilitates the use of advanced fin enhancement technology and designs to be incorporated - no other product of this type can boast such a broad range of attributes. ElfinBlock fins are both flat and consistent. With CNC fin placement to within a few microns, stacked rows align more consistently to reduce pressure drop. Superior performance combined with the ability to incorporate advanced fin enhancement such as vortex generation in the airflow allows greater spacing between fins. | 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 thicknessPerformance 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 turbulation 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. |
