Abstract
A heat exchanger and associated method are provided that may eliminate or reduce the need for an external mechanical or electrical power source to drive the fan by utilization, instead, of a Stirling engine. A heat exchanger includes a plurality of coils configured to carry a primary fluid. The heat exchanger also includes a fan including a plurality of fan blades configured to force a secondary fluid across the plurality of coils to facilitate heat transfer between the primary and secondary fluids. The heat exchanger also includes a Stirling engine operably connected to the fan and configured to cause rotation of the fan blades. A corresponding method is also provided.
