Double stack v heat exchanger

Abstract

A modular double V stacked dry or adiabatic heat exchanger having a bottom module with two heat exchangers arranged in a V-shape, a top module configured to rest atop and be supported by the bottom module and having two heat exchangers configured to continue and extend the V-shape formed by the two bottom heat exchangers, and a fan module configured to rest atop and be supported by the top module. The modules are factory assembled and configured to for easy shipping and connection to one-another on-site. Adiabatic pads or spray nozzles may be provided to pre-cool the air entering the system.
