Cooling system of battery pack for vehicle
First Claim
1. A cooling system for vehicle battery packs, the cooling system constructed such that air existing inside a vehicle in a region around a battery pack is isolated from a cabin of the vehicle and is directly introduced into the battery pack without passing through an intake duct, and the air having passed through the battery pack, which has been heated, is discharged through an exhaust duct connected to an internal space of the vehicle, in which a possibility of air to be recirculated to the region around the battery pack is low, wherein the cooling system comprises:
- a closed type housing for surrounding the outer surface of the battery pack, the battery pack including unit cells;
a plurality of intake ports formed in the housing at regions corresponding to the unit cells;
an exhaust duct connected to the housing at a region opposite to the intake ports; and
a cooling fan mounted to the exhaust duct which induces the air to flow through the plurality of intake ports and the housing and the cooling fan to the exhaust duct,wherein the internal space of the vehicle, to which the exhaust duct is connected, is a space defined between an inner panel and an outer panel of the vehicle;
wherein each of the intake ports is constructed in the shape of a slit, which corresponds to each plate-shaped unit cell of the battery pack, and the intake ports are located in correspondence to the respective unit cells; and
wherein the upper part of each intake port is constructed in a skirt structure, by which the introduction of foreign matter is prevented.

Abstract
Disclosed herein is a cooling system for vehicle battery packs, which is constructed such that an intake duct for introducing a coolant, such as air, which cools a battery pack, into the battery pack from a predetermined region is not included, air existing inside a vehicle at a region around a battery pack isolated from a cabin of the vehicle is directly introduced into the battery pack, and the air having passed through the battery pack, which has been heated, is discharged through an exhaust duct connected to an internal space of the vehicle, in which a possibility of air to be recirculated to the region around the battery pack is low. The battery pack cooling system according to the present invention uses air existing inside the vehicle. Consequently, the control of temperature and humidity is easier than when external air is used, and generation of noise and backward flow of flames and toxic gas generated during a fire, which are problems caused when the air in the cabin is used, are prevented. Furthermore, it is possible to increase the cooling efficiency of the battery pack without the provision of the intake duct for introducing air into the battery pack.
