1. A battery module cooling structure comprising:
a plurality of battery modules fixed to a vehicle body;
a cooling block, in which cooling water flows, disposed to be in contact with the plurality of battery modules to cool the plurality of battery modules; and
a plurality of valve members coupled to the cooling block and configured to control the cooling water to selectively flow in the cooling block,
wherein the cooling block comprises a first cooling module including a first cooling plate which constitutes a body of the first cooling module and in which the cooling water flows and a second cooling module including a plurality of second cooling plates of which the number corresponds to the plurality of the battery modules and in which the cooling water flows,
wherein the first cooling module is disposed at any one of upper or lower portions of the plurality of battery modules, and the second cooling module is positioned at a remaining one of the upper or lower portions of the plurality of battery modules, and
wherein the first cooling module further includes:
an inlet pipe which is coupled to the first cooling plate and allows the cooling water to flow into the first cooling plate from an outside of the battery module cooling structure;
an outlet pipe which is coupled to the first cooling plate at a position spaced apart from the inlet pipe and allows the cooling water to be discharged from the first cooling plate to the outside;
a first connecting pipe having one end coupled to the first cooling plate and another end coupled to the second cooling module; and
a second connecting pipe disposed at a position spaced apart from the first connecting pipe and having one end coupled to the first cooling plate and another end coupled to the second cooling module.
