MULTICHANNEL HEAT EXCHANGER WITH DIFFERING FIN SPACING

摘要

Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include fins of differing fin spacing. The heat exchangers include multiple sets of multichannel tubes in fluid communication with each other and fins of different spacing may be disposed between each set of multichannel tubes. In one embodiment, a first set of tubes may direct refrigerant from a first manifold to a second manifold and a second set of tubes may direct refrigerant back to the first manifold from the second manifold. The fins between the first tubes may have a relatively smaller density (e.g., fewer fins per inch) than the fins between the second tubes.
