MULTICHANNEL HEAT EXCHANGER WITH IMPROVED FLOW DISTRIBUTION |
摘要 |
Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to reduce refrigerant pressure drop through a heat exchanger manifold. In certain embodiments, tubes inserted within the manifold adjacent to a refrigerant inlet have non-rectangular or recessed end profiles configured to increase flow area near the inlet, thereby reducing a pressure drop through the manifold. In further embodiments, insertion depths of the tubes within the manifold vary based on distance from the inlet. This configuration may establish a larger flow area adjacent to the inlet, thus reducing the pressure drop and increasing heat exchanger efficiency. |
