Abstract:
In this flat extruded aluminum multi-port tube, the corrosion-resistance, at inner surfaces of a plurality of flow passages independently and parallelly extending in the tube axial direction, is effectively enhanced. In a flat extruded aluminum multi-port tube  10  formed by an extrusion by employing an aluminum tube material and an aluminum sacrificial anode material having an electrochemically lower potential than the aluminum tube material, the aluminum sacrificial anode material is exposed to form a sacrificial anode portion  18  at least in a part of an inner circumferential portion in each of the plurality of flow passages  12.

Claim (Index 4):
The aluminum multi-port tube according to  claim 1 , wherein the sacrificial anode portion exists at the internal partition wall portion positioned between adjacent ones of the plurality of flow passages, in a ratio not higher than 100% of a thickness of the internal partition wall portion.
