摘要： PROBLEM TO BE SOLVED: To obtain a heat transfer tube with high heat transfer performance by reducing the liquid film thickness of liquid refrigerant flowing inside the heat transfer tube. SOLUTION: The cross-sectional outline of a heat transfer tube 10 is formed into an elliptic shape, and it is provided with a rail 11 guiding refrigerant to the inner surface, and a flow-collecting passage 12 not provided with this rail 11. The rail 11 is inclined to allow the refrigerant to flow into the flow- collecting passage 12, and the flow-collecting passage 12 is provided at the side 10b in the downstream side in an air flow direction (the direction of an arrow 15). Consequently, the thickness of a refrigerant liquid film of the side 10a in the upstream side of the air flow direction (the direction of the arrow 15) is reduced so as to improve the heat transfer coefficient of the air and refrigerant, when the liquid refrigerant flows in the tube.
