초록 ▼

A battery pack cooling mechanism for a hybrid vehicle is provided. An opening is formed in a floor panel located rearwardly of the vehicle. An upper portion of a battery pack inserted into the opening is closed by a cover panel. The opening is formed in misalignment with above an exhaust pipe so that the battery pack is arranged adjacent the exhaust pipe in the width-wise direction of the vehicle. An air-intake device is mounted on a top surface of the battery pack. An air outlet port of the air-intake device opens frontward of the vehicle. An air outlet port of an air outlet duct opens more rearwardly than the battery pack. A filer element which removes foreign substances is disposed in the air-intake device. A service lid is disposed on an upper portion of the cover panel for maintenance of the filter element.

1. A battery pack cooling mechanism for a hybrid vehicle comprising: a pair of right and left rear side members which are disposed under a floor panel at a rear portion of a hybrid vehicle and are longitudinal in a front-back direction of the hybrid vehicle; an exhaust pipe which is laid longitudinally along one of said rear side members in the front-back direction of the hybrid vehicle, said exhaust pipe having an open vehicle-rear-end;a battery pack which is arranged next to said exhaust pipe in a width-wise direction of the hybrid vehicle and in which battery pack components are stored;a cooling fan which introduces outside air into said battery pack to cool the battery pack components stored in said battery pack;an opening which opens to said floor panel at a location which does not overlap said exhaust pipe in an upward direction of the hybrid vehicle and in which an upper portion of said battery pack is inserted;a cover panel installed on said floor panel to cover the upper portion of said battery pack;an air inlet port which opens toward a space between a ceiling surface of said cover panel and a top surface of said battery pack to introduce the outside air into said battery pack for cooling said battery pack; andan air outlet port from which the air in said battery pack is discharged. 2. A battery pack cooling mechanism as set forth in claim 1, further comprising a sub-frame on which said battery pack is mounted and which has side portions arrayed in the width-wise direction of the hybrid vehicle, the side portions being joined to said rear side members, respectively, and wherein said sub-frame is equipped with a connecting frame which is disposed between a side edge of said opening and said exhaust pipe above said exhaust pipe in the upper-lower direction of the hybrid vehicle and longitudinal in the front-back direction of the hybrid vehicle. 3. A battery pack cooling mechanism as set forth in claim 1, further comprising an air-intake device which is mounted on a top surface of the battery pack and communicates between an air inlet through which the outside air is taken into said battery pack and said air inlet port, and wherein said air inlet port opens frontward of the hybrid vehicle at a location next to the front edge of the top surface of said battery pack. 4. A battery pack cooling mechanism as set forth in claim 3, wherein said air-intake device includes a body and a cover which are separable up and down, and wherein a filter element which removes a foreign substance contained in the air is disposed between said body and the cover. 5. A battery pack cooling mechanism as set forth in claim 4, wherein a service lid used for maintenance of said filter element is so disposed as to form a ceiling surface of said cover panel. 6. A battery pack cooling mechanism as set forth in claim 1, wherein said air outlet port opens rearwardly of the hybrid vehicle at a location closer to the rear of the vehicle than a vehicle-backward wall of said battery pack is, and an air outlet duct which communicates between an air-discharge outlet from which the air in said battery pack is discharged and said air outlet port is mounted on the vehicle-backward wall of said battery pack.
