PURPOSE: A water-cooling secondary battery is provided to improve thermal conductivity of a contacted part of a heat radiating plate and cooling pipe by forming the cooling pipe in the edge part of the heat radiating part, thereby improving cooling efficiency. CONSTITUTION: A water-cooling secondary battery(1000) comprises: a plurality of battery cells(100); and a heat radiating plate(200) which is inserted between the battery cells, and is formed to be wider than the electrode of the battery cell. The heat radiating plate has a cooling pipe(210) in the edge part thereof. The secondary battery additionally includes an inlet manifold(300) which is connected to the inlet(211) of the cooling pipe, and has inlet pipe(310) formed on one side; and an outlet manifold(400) which is connected to the outlet(212) of the cooling pipe, and has outlet pipe(410). |
