Title: Paul A. Lindahl, Jr.: Inventor of a Water-Conserving Cooling Tower

Introduction

Paul A. Lindahl, Jr. is an inventor associated with Overland Park, Kansas, and The Marley Cooling Tower Company. His work includes a patented cooling-tower design intended to conserve water and reduce the effects of heated, moist discharge air. Lindahl is credited with 1 patent.

Latest Patents

Lindahl’s listed patent is “Bottom Vented Wet-Dry Water Cooling Tower.” The invention describes a generally rectangular, mechanical-draft cooling tower that combines wet and dry cooling sections. Its design aims to conserve water, limit the recirculation of heated discharge air, and reduce visible fog plumes.

The tower uses elevated, obliquely positioned heat-exchange conduit banks and evaporative cooling sections that receive partially cooled water. Separate induced-draft fans draw air through the dry and evaporative sections, then discharge the resulting dry and moist airstreams upward in separate paths. The dry air is arranged to partially surround the central moist airstream, helping reduce its low-level deflection and spread.

The tower’s bottom-vented configuration allows prevailing winds to pass beneath the dry-section banks and through the structure. This airflow helps relieve negative-pressure eddies on the tower’s lee side, reducing the likelihood that hot discharge air will recirculate into the air inlets. The design also seeks to minimize moisture deposition on nearby equipment and structures.

Career Highlights

Lindahl’s documented patent work reflects an engineering focus on cooling-tower performance, water conservation, and management of discharge airflow. His listed invention combines wet and dry cooling methods with airflow features intended to address recirculation and fog formation.
