摘要： There is provided an extruded aluminum flat multi-hole tube that is a flat multi-hole tube made of aluminum or aluminum alloy and manufactured by extrusion molding. The flat multi-hole tube comprises therein a plurality of refrigerant passages extending in a tube length direction and including an upper wall surface and a lower wall surface opposed to each other and a pair of opposed sidewall surfaces. A ridge extending in the tube length direction is formed only on the upper wall surface of the refrigerant passage. The height of the ridge is 5 to 25% of the vertical width of the refrigerant passage. The ratio of the horizontal width at 1/2 the height of the ridge with respect to the horizontal width of the refrigerant passage is 0.05 to 0.30. The ratio of the horizontal width per inter-ridge flat portion of the upper wall surface with respect to the horizontal width of the refrigerant passage is 0.20 or less. The present invention can provide an extruded aluminum flat multi-hole tube suppressing an increase in flow resistance due to the ridge and having high heat-transfer performance.
