The components of an air heat exchanger are numerous, with the main ones including:

1. The restraint is composed of a combination of a casing, finned tube, and frame. Fluids requiring cooling or condensation flow through the tubes, while air flows across the finned tube bundle externally, cooling or condensing the hot fluid through heat exchange.

Axial Flow Fan: A group of one or more axial flow fans drives the airflow.

3. Structure: Support components for the air heat exchanger tube bundle and fans.

4. Attachment: Louvers, steam coils, ladders, platforms, etc.
