Abstract

Designs of heat exchangers and components thereof are provided, and methods for their manufacture. The heat exchangers are designed to manage condensation and heat transfer effectiveness, which can minimize air side pressure drop and can be used to improve both refrigerant effectiveness and overall system performance. Flow rectification design features are also described.
