  • Publication number: 20210348543
    Abstract: A cooling apparatus (10) for a vehicle includes air-cooling first and second heat exchangers (12, 14) that are placed beside each other. A coolant flow-out portion (32) of the first heat exchanger (12) from which a first coolant which is a cooling target of the first heat exchanger (12) flows out and a coolant flow-out portion (36) of the second heat exchanger (14) from which a second coolant which is a cooling target of the second heat exchanger (14) flows out are placed at ends at opposite positions separated along a diagonal line on a parallel placement surface of the two heat exchangers (12, 14). A first cooling fan (20) is placed opposing the coolant flow-out portion (32) of the first heat exchanger (12), and a second cooling fan (22) is placed opposing the coolant flow-out portion (36) of the second heat exchanger (14). With this configuration, cooling performance of two air-cooling heat exchangers placed beside each other can be improved.

  • Patent number: 10744855
    Abstract: A cooling device for a vehicle includes a mechanical fan configured to be driven by a driving force of the engine, an engine cooling heat exchanger disposed forward of the mechanical fan in a front-rear direction of the vehicle, a first heat exchanger and a second heat exchanger that are disposed forward of the engine cooling heat exchanger in the front-rear direction of the vehicle, a first electric fan that includes a first motor and cools the first heat exchanger, and a second electric fan that includes a second motor and cools the second heat exchanger. The first motor and the second motor are disposed forward of the first heat exchanger and the second heat exchanger, respectively, in the front-rear direction of the vehicle such that the first motor and the second motor do not overlap the coupling when viewed in a front direction of the vehicle.
