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 1):
An aluminum multi-port tube with a generally flat cross sectional shape obtained by extruding an aluminum material, the aluminum multi-port tube being an extruded tube which has a plurality of flow passages extending independently of each other in an axial direction of the tube, the flow passages being arranged in a longitudinal direction of the flat cross sectional shape via internal partition wall portions extending in the axial direction of the tube in a peripheral wall portion of the tube, characterized in that:\n the aluminum multi-port tube is formed by extrusion wherein an aluminum tube material and an aluminum sacrificial anode material having an electrochemically lower potential than the aluminum tube material are employed as said aluminum material, and the aluminum sacrificial anode material is exposed to form a sacrificial anode portion at least in a part of an inner circumferential portion in cross section of each of the plurality of flow passages, whereby the aluminum multi-port tube has an excellent internal corrosion-resistance.
