Air-cooled heat exchangers and evaporative cooling assemblies

Abstract

An air-cooled heat exchanger includes an airflow path, a fan configured to bias an airflow through the airflow path, a coil disposed in the airflow path and configured to receive a first fluid such that the coil enables a first heat exchange relationship between the first fluid and the airflow, and an evaporative cooling assembly. The evaporative cooling assembly is disposed in the airflow path upstream of the coil relative to the airflow. Further, the evaporative cooling assembly includes a number of microporous hollow fibers configured to receive a second fluid such that the evaporative cooling assembly enables a second heat exchange relationship between the second fluid and the airflow.
