WIPO Patent Application WO/2007/135934

Kind Code:

Abstract:

A cooling device (40) is provided with a cooling fan (F10) arranged on the side of an electrical storage device (C1), an exhaust port (44) arranged on the side of a battery (B), and a cooling wind flow channel for permitting cooling wind from the cooling fan (F10) to flow. As for the electrical storage device (C1) and the battery (B), a space inside the case (50) communicates with a space inside a case (52) by an opening section (46). Cooling wind supplied from the air blowing fan (F10) circulates through the space formed inside the case (50) of the electrical storage device (C1) and cools capacitor cells (CC1-CC5). When the cooling wind passed through the electrical storage device (C1) is introduced into a case (52) of the battery (B) through an opening section (46), the cooling wind cools the battery cells (BC1-BC6) by circulating in a space between the upper surface of the battery cells (BC1-BC6) and the case (52) and spaces between the battery cells. Then, the cooling wind is discharged to the external of the case (52) through the exhaust port (44).
