Wrapped fin heat exchanger

摘要

A wrapped fin heat exchanger formed from a continuous length of tubing having a fin wrapped thereabout to provide an enhanced heat transfer surface is disclosed. A cylindrical core portion is formed from loops of tubing and a second cylindrical locking portion is mounted thereabout. The locking portion has bands which extend about and in engagement with the loops of the core portion to secure the heat exchanger in a predetermined configuration. By utilization of the locking portion and the core portion the unwinding of the heat exchanger is prevented and its structural integrity is maintained for subsequent manufacturing operations.
