Abstract
Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to promote flow of refrigerant within the multichannel tubes near the edges of the tubes that are contacted first by an external fluid. The tube configurations include flow paths of varying cross-sections, spacings, and sizes. Flow control mechanisms, such as inserts, blocking plates, sleeves, crimped sections, and crushed sections, may be employed with the flow paths to favor flow near the edges of the tubes that are contacted first by an external fluid.
