Problems solved by technology

[0006] That is, in Publication No. '605, there is only a small amount of air in contact with the case wall - the case wall serves as a heat release surface for air intake, air passing through the battery cell, and exhaust to the outside, Thus the heat released to the outside is insufficient
[0007] Therefore, regarding the point of efficiently releasing the heat generated by the battery to the outside of the case, a sufficient effect cannot be obtained in the conventional system, and there is room for improvement

Abstract

The invention provides a battery cooling system (1), comprising: a casing (2) having walls surrounding an interior space in which a plurality of batteries (3) are accommodated; a blower (4) , the blower (4) is accommodated in the casing (2) and circulates fluid for cooling the plurality of battery cells (3) inside the casing (2); and a wall passage forming member (9). The wall passage forming member (9) forms a wall passage (611, 612, 622, 621). The wall passage forming member (9) has an inflow part and an outflow part through which the fluid from the blower (4) passes when flowing into the wall passage before contacting the battery (3), and the fluid from the inflow part entering the wall passage Passes through the outflow when flowing out of the wall passage.

Description

technical field [0001] The invention relates to a battery cooling system for cooling a battery accommodated in a casing. Background technique [0002] The system disclosed in Japanese Patent Application Laid-Open Publication No. 2013-86605 connects an intake duct and an exhaust duct to an encapsulation case housing a plurality of battery cells, and sends air supplied from a cooling fan into the case through the intake duct , and the air is exhausted to the outside through the exhaust duct after heat exchange with the battery cells. [0003] That is, the air exhausted to the outside after the heat exchange will not immediately return to the inside of the case, and new air for cooling the battery is always sent into the inside of the case. [0004] In the system of publication No. '605, the air supplied from the cooling fan flows toward the battery cells after passing through the inside of the intake duct. [0005] Then, the air immediately after passing through the battery ...
