US 7,730,734 B2 · Cooling apparatus of a fuel cell vehicle

Abstract

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.

Dependent claims

A cooling apparatus of a fuel cell vehicle comprising:

a cooling fan;
a fuel cell cooling heat exchanger;
and
an air conditioner external heat exchanger having a high-temperature portion,
wherein the air conditioner external heat exchanger is disposed upstream of the fuel cell cooling heat exchanger in a passing air flow direction, and the air conditioner external heat exchanger and the fuel cell cooling heat exchanger are partially offset from each other so that the 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, and
wherein the cooling fan is disposed downstream of the fuel cell cooling heat exchanger and a fan shroud of the cooling fan surrounds the contour of the air conditioner external heat exchanger.
