But rising to the task at hand, the engineering team devised clever designs that addressed all the problems while staying within the constraints. We redesigned and re–engineered the heat exchangers with an VRcooler geometry, taking care to ensure that the overall size was still the same, even though we were using fins of a different size 25.4 x 15.875 x 5/16”.
We utilized the window Fin design for the project. When tested by the clients, the new improved design was found to have 2 ~ 4% higher capacity, and also showed a reduced air pressure drop. The window fin also had a lower fin width than the design that the client was then using, thus leading to lower energy costs.
Needless to say, the client was pleased with the new coils and we are now one of their major suppliers.
