Battery cooling structure

摘要

A battery cooling structure is provided in which since a battery support member (43) that is disposed above a lower layer battery group (B4, B5) and supports an upper layer battery group (B6) on its upper face is formed so as to be hollow, and the upper layer battery group (B6) is cooled by a cooling medium that flows in an interior of the battery support member (43), due to the battery support member (43) having the dual function of supporting the upper layer battery group (B6) and cooling the upper layer battery group (B6), it is possible to cut the number of components and simplify the structure. Moreover, since the cooling medium flows in the interior of the battery support member (43) and does not come into direct contact with the upper layer battery group (B6), the upper layer battery group (B6) is not contaminated by the cooling medium.

主权项

1. A battery cooling structure, comprising:
a lower layer battery group which is placed on a tray, a battery support member disposed above the lower layer battery group, and an upper layer battery group supported on an upper face of the battery support member, wherein the lower layer battery group and the upper layer battery group are cooled by the flow of a cooling medium, wherein the battery support member is formed to provide a bridge between a first leg portion and a second leg portion which are standingly provided on the tray with a distance therebetween, the battery support member and the first and second leg portions being hollow, and wherein the upper layer battery group is cooled by a cooling medium that flows in an interior of the battery support member and the first and second leg portions.
