AI Technical Summary
⚠Technical Problem
Existing air-cooled heat exchangers in industrial processes occupy a significant plot area and require multiple fans, limiting efficiency and increasing costs, while current designs do not effectively utilize larger fan diameters for improved performance.
⚗Method used
An air-cooled heat exchanger design featuring a single bay with multiple tube bundles and a single large-diameter fan, supported by a framework, which enhances airflow efficiency and reduces the overall size and power requirements.
🎯Benefits of technology
The design achieves improved air cooling performance, reduces plot area, and lowers installation costs by utilizing larger fans with higher static efficiency, leading to increased production rates and reduced energy consumption.

Abstract
An air-cooled heat exchanger includes a bay having tube bundles that receive a process fluid. A framework supports a fan shroud and the bay with the single fan shroud positioned adjacent to the tube bundles. A single fan is rotatably positioned within the fan shroud so that rotation of the fan causes air flow over the tube bundles so that process fluids within the tube bundles are cooled. A fan motor is mounted on the framework and rotates the fan.
