Water-cooled battery module and water-cooled battery cooling apparatus using the same

A water-cooled battery cooling apparatus comprising:

• a water-cooled battery module including a first water-cooled battery module and a second water-cooled battery module disposed to be parallel to the first water-cooled battery module;
• a coupling member configured to couple the first water-cooled battery module and the second water-cooled battery module;
• an inlet manifold configured to allow a coolant to be introduced to the water-cooled battery module;
• and
• an outlet manifold spaced apart from the inlet manifold and configured to discharge the coolant from the water-cooled battery module,
• wherein
• the water-cooled battery module comprises:
• a plurality of stacked battery cells;
• and
• a cooling unit installed in the plurality of battery cells and configured to cool the plurality of battery cells,
• the cooling unit comprises:
• includes an inlet pipe to which a coolant is introduced;
• an outlet pipe spaced apart from the inlet pipe and configured to discharge the coolant introduced from the inlet pipe;
• and
• a plurality of cooling channel units configured to connect the inlet pipe and the outlet pipe and accommodate the coolant introduced from the inlet pipe therein to dissipate heat generated by the plurality of battery cells, and
• the cooling channel units are disposed to be parallel between the plurality of battery cells and disposed to be in surface-contact with the plurality of battery cells.
