Patent number: 9966640Abstract: The efficiency in layout of an exhaust space for a power source apparatus mounted in an in-car space is increased and uncomfortableness is suppressed due to air discharged from the power source apparatus into the in-car space. A vehicle on which a power source apparatus is mounted includes the power source apparatus disposed in an in-car space of the vehicle, a cooling apparatus supplying air within the in-car space to the power source apparatus, and a cooling duct which the air discharged from the power source apparatus flows. The cooling duct is connected to any one of a first cooling flow path formed by a pillar of the vehicle, a second cooling flow path formed by a frame portion of the vehicle and a stepped portion provided for the frame portion, and a third cooling flow path formed by the frame portion and a scuff plate portion.Type: GrantFiled: August 31, 2011Date of Patent: May 8, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takanori Kumagai, Noboru Oota, Tetsuo Ohdai
