Title:
BATTERY COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/241431
Kind Code:
A1
Abstract:
[Problem] To suppress variation in temperature among multiple heat exchange units while reducing total pressure loss caused at the multiple heat exchange units. [Solution] A battery cooling device is equipped with multiple heat exchange units (10) each having a heat transfer medium path (11) therein. The multiple heat exchange units are divided into multiple heat exchange unit groups (G1, G2, G3). Each heat exchange unit group comprises multiple heat exchange units, and the multiple heat exchange units belonging to one heat exchange unit group are connected in parallel such that flow rates of a heat transfer medium passing through each of the multiple heat exchange units are substantially the same. The multiple heat exchange unit groups are connected in series, and the number of heat exchange units belonging to a heat exchange unit group located relatively on the upstream side is greater than the number of heat exchange units belonging to a heat exchange unit group located relatively on the downstream side. Thus, the flow rate of the heat transfer medium passing through each one of the heat exchange units belonging to the heat exchange unit group located relatively on the downstream side is greater than the flow rate of the heat transfer medium passing through each one of the heat exchange units belonging to the heat exchange unit group located relatively on the upstream side.
