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 tubeformed 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 portionat least in a part of an inner circumferential portion in each of the plurality of flow passages

Flat extruded aluminum multi-port tube whose inner surface is highly corrosion-resistant and an aluminum heat exchanger using the tube

A condenser has a core part having tubes, a first modulator tank and a second modulator tank. The first modulator tank is provided along a side portion of a header tank. The second modulator tank communicates with an interior of the first modulator tank and is provided along a lower edge of the core part in a gravity direction. An interior of the header tank is provided with a communicating space that communicates with the interior of the first modulator tank and an interior of the second modulator tank. The header tank has an introduction passage that guides liquid-phase refrigerant in the communicating space to a supercooling portion of the core part. A first connection part between the communicating space and the introduction passage is disposed on a lower side, in the gravity direction, of a second connection part between the communicating space and the second modulator tank.
