Zusammenfassung:The present invention provides a battery cooling device for an electric vehicle having an improved heat exchange structure to efficiently cool a battery. According to the present invention, the device comprises: an upper plate having an inlet hole introducing coolant and an outlet hole discharging the flowing coolant on one side, and at least one seating part where a battery is placed formed on the upper side; and a lower plate fastened to the upper plate to form a flow path through which the coolant circulates therein, wherein the flow path includes: a first flow path having one end communicated with the inlet hole for the coolant introduced from the inlet hole to pass through a part of the seating part; and a second flow path having one end communicated with the other end of the first flow path and the other end communicated with the outlet hole for the coolant to pass through the remaining part of the seating part to be discharged to the outlet hole. 본 발명은, 일측에 냉각수가 유입되는 유입홀과 유동된 냉각수가 배출되는 배출홀이 형성되고, 상측면에 배터리가 안치되는 적어도 한 개 이상의 안치부가 형성되는 상부판; 및 상기 상부판과 체결되어 내부에 냉각수가 순환되는 유로부를 형성하는 하부판;을 포함하고, 상기 유로부는 일단이 상기 유입홀과 연통되어 상기 유입홀으로부터 유입된 냉각수가 상기 안치부의 일부분을 지나가도록 형성되는 제1 유로와, 일단이 상기 제1 유로의 타단과 연통되고 타단이 상기 배출홀과 연통되어 냉각수가 상기 안치부의 남은 부분을 지나가서 상기 배출홀으로 배출되도록 형성되는 제2 유로를 포함하는 전기자동차용 배터리냉각장치를 제공한다.
