摘要： A battery module includes: a cell cover close to a battery cell and having one surface emitting heat of the battery cell; and a cooling channel portion having a cooling channel that a refrigerant flows formed therein and having one surface of the cooling channel close to the one surface of the cell cover to absorb heat of the battery cell. In a contact region of the cell cover and the cooling channel portion, the cell cover has a protrusion portion protruded in the direction of the cooling channel, and the cooling channel has a penetration hole for inserting the protrusion portion into an inner portion that the refrigerant flows.

摘要： A battery cooling device for a vehicle is provided. The device repeats phase changes of a refrigerant to cool a battery due to heat of vaporization when a liquid-state refrigerant is vaporized by thermally coming in contact with a battery heat source. The vaporized refrigerant is changed back into a liquid state by thermally coming in contact with a separate coolant. The effect of cooling all battery cells is maximized throughout the entire refrigerant channel for cooling a battery and the battery cells are cooled uniformly.
