| 摘要 |
The present invention relates to a heat sink for preventing a battery formed at an electric vehicle from being overheated and, more particularly, to a battery heat sink having a structure of a stacked fluid path, which is capable of improving heat exchange efficiency of a heat sink, being easily manufactured and greatly reducing the manufacturing cost. To this end, the present invention includes an upper plate disposed to make direct contact with the plurality of battery cells; a lower plate disposed below the upper plate and spaced apart from the upper plate; a middle plate interposed between the upper and lower plates and having a cooling water circulation path through which cooling water flows; an inflow pipe which is connected to an inlet of the cooling water circulation path formed in the middle plate and through which the cooling water flows; an exhaust pipe connected to an outlet of the cooling water circulation path formed in the middle plate and through which the cooling water is discharged; and a coupling member for coupling the upper, lower and middle plates to each other. |
