Abstract
A heat exchanger tube (1), wherein a plurality of refrigerant passages (5) extending in the longitudinal direction of the tube are formed in a flat tube body (2) with a specified length parallel with each other in the lateral direction of the tube and, where the overall cross sectional area of the tube body (2) is (At), the overall cross sectional area of the refrigerant passage (5) is (Ac), the outer peripheral length of the tube body (2) is (L), and the overall inner peripheral length of the refrigerant passage (5) is (P), set so that the relation of Ac/At×100=30 to 55 and P/L×100=150 to 325 can be established, whereby a heat exchanging performance can be increased.
