Abstract
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.
Claims26
A hybrid vehicle, including a fuel cell, having a cooling system which is installed in the vehicle, comprising:
- a passenger compartment including an air conditioning system;
- a driving device which drives the vehicle using electric power supplied and generated from the fuel cell;
- a first heat exchanger for the air conditioning system;
- a second heat exchanger that cools the fuel cell;
- and
- a third heat exchanger for a driving device
- wherein the first to third heat exchangers are arranged in one plane substantially perpendicular to a direction in which the vehicle moves, at a front portion of the vehicle, and
- wherein the first to third heat exchangers are arranged on top of one another in a vertical direction in the one plane.
A hybrid vehicle, including a fuel cell, having a cooling system which is installed in the vehicle, comprising:
- a passenger compartment including an air conditioning system;
- a driving device which drives the vehicle using electric power supplied and generated from the fuel cell;
- a first heat exchanger for the air conditioning system which performs heat exchange with the outside air;
- a second heat exchanger that cools the fuel cell which performs heat exchange with the outside air;
- and
- a third heat exchanger for a driving device which performs heat exchange with the outside air,
- wherein the first to third heat exchangers are arranged in one plane orthogonal to a longitudinal direction of the vehicle, at a front portion of the vehicle, according to heat loads of objects to be cooled by the first to third heat exchangers, and
- wherein the first to third heat exchangers are arranged on top of one another in a vertical direction in the one plane.
