Definitions

  • plural flat-tube groups each including plural flat tubes are connected by a fin.
  • This configuration makes it possible to improve the pressure resistance of the tubes through which refrigerant is passed, and reduce the thickness of the fin to thereby also reduce the weight of the fin.
  • a heat-exchanger, a heat-exchanger unit, and a refrigeration-cycle apparatus that have improved heat-exchange performance and are also easy to manufacture can be provided.
  • Embodiment 1 air flows into the heat-exchanger 100 in the x-direction. Because of the inclined placement of the first portion 31 of the fin 30 as described above, air flows in a meandering manner in the gap between the first flat tube 20a, the second flat tube 20b, and the fin 30. This results in increased heat-transfer area and consequently improved heat-transfer performance of the heat-exchanger 100. As the airflow is deflected at the first portion 31 of the fin 30, incoming air collides with a side wall 23b of the second flat tube 20b. The collision of air causes disturbances in the flow of air between the second flat tubes 20b.
