摘要： A heat transfer tube and a heat exchanger incorporating at least one heat transfer tube are provided. The heat transfer tube and the heat exchanger are optimized for use within an air conditioner (which is configured to operate only in a cooling mode). The heat transfer tube includes a tube body with an interior surface and an exterior surface. The tube body defining an outer diameter (Do) and a wall thickness (WT), wherein a ratio (WT/Do) the wall thickness (WT) to the outer diameter (Do) is between 0.061 and 0.071. The heat transfer tube includes multiple pluralities of adjacent helical fins protruding circumferentially around the interior surface of the tube body at respective helix angles. The multiple pluralities are separated by one or more transition area(s).

摘要： A heat transfer tube and a heat exchanger incorporating at least one heat transfer tubes are provided. The heat transfer tube and the heat exchanger are configured to operate in both a heating mode and a cooling mode (e.g., to optimize the reversible function a heat pump). The heat transfer tube includes a tube body with an interior surface and an exterior surface. The tube body defining an outer diameter (Do) and a wall thickness (WT), wherein a ratio (WT/Do) the wall thickness (WT) to the outer diameter (Do) is between 0.061 and 0.071. The heat transfer tube includes a plurality of adjacent helical fins protruding circumferentially around the interior surface of the tube body, and at least one groove disposed between the plurality of adjacent helical fins. The configuration of the heat transfer tube(s) is optimal for the reversible function of the heat pump.

摘要： A heat exchanger includes a plurality of heat exchange tube segments defining a plurality of fluid pathways therein and a bend formed in the plurality of heat exchange tube segments defining a first leg of the heat exchanger positioned at a first side of the bend, and a second leg of the heat exchanger positioned at a second side of the bend opposite the first side. The heat exchanger is positioned relative to a flow direction of an incoming airflow such that the bend is closer to a source of the incoming airflow than the first leg and the second leg.
