Battery cooling structure for vehicle

A battery cooling structure for a vehicle, comprising:

• a battery module that is located under a vehicle body floor part, that is fixed to a frame of a vehicle body via a battery frame having a rear frame disposed at a lower side of a rear face of the battery module and protruded from the rear face toward a rear of the vehicle body, the battery module being arranged next to the rear frame in a stepwise manner in a side view, a clearance is formed between a top face of the battery module and the vehicle body floor part and an airflow that is introduced from a front side of the vehicle body into the clearance is discharged from a rear end of the clearance;
• a slant wall formed in the vehicle body floor part, and slanted downward along a direction toward the rear of the vehicle body so as to gradually decrease an area of a cross-section of the clearance, the cross-section being perpendicular to a longitudinal direction of the vehicle body, along the direction toward the rear of the vehicle body;
• a middle wall that is formed in the vehicle body floor part, that extends from a rear end of the slant wall toward the rear of the vehicle body, and that extends beyond a rear end of the battery module in the direction toward the rear of the vehicle body;
• a vertical wall that is formed in the vehicle body floor part, that extends from a rear end of the middle wall downward in a height direction of the vehicle body such that a space through which the clearance is communicated with a space outside of the vehicle body is formed between the battery module and the vertical wall;
• and
• a lower wall that is formed in the vehicle body floor part, that extends from a lower end of the vertical wall toward the rear of the vehicle body, and that is arranged at substantially the same height as a bottom face of the battery module.
