<p><P>PROBLEM TO BE SOLVED: To provide a battery-cooling structure of which freedom of layout of an intake duct and an exhaust duct supplying and exhausting cooling air to and from a battery box equipped with a U-shaped cooling passage. <P>SOLUTION: On a cooling air guiding part B formed integrally to a battery housing part A of a battery box 18, a lower side cooling air inlet passage 40 and an upper side cooling air exhaust passage 44 are separated by a horizontally extended separation wall 39, a cooling air inlet port 41 at upstream side of the cooling air inlet passage 40 is connected to the intake duct, a first communication port 42 at down stream side is connected to the upstream side of the cooling passage 36, a cooling air exhaust port 45 at the downstream side of the cooling air exhaust passage 44 is connected to the exhaust duct, and a second communication port 43 at upstream side is connected to the downstream side of the cooling passage 37, As a result, it becomes possible to set the location of the cooling air introduction port 41 and the cooling air exhaust port 45 of the cooling air guiding part B, without being restricted by the position of the first communication pore 42 and the second communication port 43 that communicate with cooling passages 36, 37 of the cooling air guiding part B. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
