Disclosed is a heat sink having two or more separated flow paths. The heat sink, according to the present invention, is a heat sink having a cooling path through which a refrigerant passes to cool, by using an indirect cooling method, a secondary battery including a cell assembly in which at least two unit cells including cathode plates, separation films, and anode plates are stacked and each cathode lead and each anode lead are electrically connected to a plurality of cathode tabs and anode tabs protruding from the cathode plates and the anode plates of the respective unit cells, wherein the cooling path has two or more separated flow paths. According to the present invention, it is possible to provide a heat sink capable of providing a uniform cooling effect. |
