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 cooling apparatus of a fuel cell vehicle in which a cooling efficiency of a fuel cell cooling heat exchanger located downstream of an air conditioner external heat exchanger does not decrease. (1) In the cooling apparatus, the air conditioner external heat exchanger and the fuel cell cooling heat exchanger are partially offset from each other so that a high-temperature portion of the air conditioner external heat exchanger is not overlapped with the fuel cell cooling heat exchanger in a front view taken from a front side of the vehicle. (2) A portion of the fuel cell cooling heat exchanger extending beyond an end of the air conditioner exterior heat exchanger opposite the high-temperature portion is disposed outside a fan shroud so as to be cooled by a vehicle-running wind only.

Cooling apparatus of a fuel cell vehicle

A FC radiator in a FC cooling system, an EV radiator in a driving device cooling system, and a condenser in an air conditioning cooling system are arranged in one plane substantially perpendicular to a direction in which a fuel cell vehicle moves forward at a front portion of the fuel cell. Also, heat exchangers are arranged in order of the condenser, the EV radiator, and the FC radiator, that is, in order of an operating temperature from an upper position to a lower position. An angle of plural fins fitted to a front grille is changed according to a load of a fuel cell and a vehicle speed, each of the plural fins being formed to have an elongate rectangular plate shape extending in a horizontal direction.

Cooling system and hybrid vehicle including cooling system

A heat exchange portion is configured by arranging a condenser for air conditioning, an EV radiator, and a FC radiator in one plane substantially perpendicular to a direction in which a fuel cell vehicle moves, at a front portion of the fuel cell vehicle, in order of an operating temperature, from an upper position to a lower position. A fan is provided behind the heat exchange portion such that a center thereof is closer to the condenser than to the FC radiator. In addition, a fan shroud is provided, in which plural ram pressure holes are formed in a portion which covers the FC radiator.
