Sealed Type Heat Exchanging System of Battery Pack

The present invention, more particularly, to a hermetic surrounding the outer surface of the battery pack to be formed with a predetermined flow path for the movement of the heat exchange medium for the housing to a system for temperature control of the middle- or large-sized battery pack including a plurality of unit cells and it provides a battery pack heat exchange system configured located in the housing and driving the fan for the flow of the heat exchange medium, and is located on a side of the housing to comprise a heat exchanger for adjusting the temperature of the heat exchange medium for . Heat exchange system of the present invention by circulating internally by the heat exchanger without introducing the for battery pack heat-exchanged air from the outside of the system, reducing the size of the battery system, and not affected by external conditions, to decrease the noise not only it has the effect that can be adjusted to the optimum operating temperature of the cell pack effectively.
