Battery case

摘要

The present invention relates to a battery case for a vehicle, and more particularly to a battery case for effectively lowering or raising the temperature of a battery module consisting of a plurality of batteries used in a vehicle or mechanical apparatus. According to the present invention, a battery case includes: a lower frame with an upper open part; a lower plate fixed to the lower frame for holding the battery module thereon, the lower plate being formed lengthwise with an inlet hole, an outlet hole, and a heat exchange hole; an inner upper frame with an upper surface having a terminal through-hole for enclosing the battery module; a front frame attached to an open front of the inner upper frame for holding a suction fan at the lower part thereof; an outer upper frame with an upper surface having a terminal through-hole for enclosing the inner upper frame and the front frame; a rear plate attached to the rear of the outer upper frame for holding an exhaust fan; and a guide partition wall arranged in the side of the inner upper frame so as to closely contact the battery module, characterized in that the guide partition wall guides the cooling (heating) air sucked by the suction fan along a zigzag path from the lower part of the side of the battery module to the upper part thereof to the exhaust fan.

1. A battery case comprising:
a lower frame with an upper open part; a lower plate fixed to the lower frame for holding the battery module thereon, the lower plate being formed lengthwise with an inlet hole, an outlet hole, and a heat exchange hole; an inner upper frame with an upper surface having a terminal through-hole for enclosing the battery module; a front frame attached to an open front of the inner upper frame for holding a suction fan at the lower part thereof; an outer upper frame with an upper surface having a terminal through-hole for enclosing the inner upper frame and the front frame; a rear plate attached to the rear of the outer upper frame for holding an exhaust fan; and a guide partition wall arranged in the side of the inner upper frame so as to closely contact the battery module, characterized in that the guide partition wall guides cooling (heating) air sucked by the suction fan along a zigzag path from the lower part of the side of the battery module to the upper part thereof to the exhaust fan,
wherein a portion of the cooling (heating) air sucked from the suction fan of the front frame flows to both sides of the battery module along the guide partition wall,and wherein the remaining cooling (heating) air flows into the inlet hole of the lower plate and flows to the rear through a space between the lower plate and the lower frame which are under the lower surface of the battery module.
