DYNAMIC SURFACE AREA EXPANSION IN A REAR DOOR HEAT EXCHANGER

摘要

A rear door heat exchanger includes a door frame have opposing first and second edges, a fluid supply manifold secured along the first edge of the door frame, a fluid return manifold secured along the second edge of the door frame, a fin tube assembly including a plurality of fin tubes extending across a central region of the rear door heat exchanger and forming an air flow pathway through the fin tube assembly, and an actuator for controllably moving the fin tube assembly between retracted and extended positions. The rear door heat exchanger further comprises a plurality of supply pipe coupling assemblies and a plurality of return pipe coupling assemblies, each pipe coupling assembly providing fluid communication between one of the manifolds and one of the fin tubes.
