The present invention relates to a cooling apparatus for a battery for an electric vehicle, comprising a body (10) in which cooling water is circulated. The body (10) includes an inlet (11) and an outlet (12) for circulating the cooling water through a flowing water space unit (14) formed in the body (10). The flowing water space unit (14) includes a flow path unit (30) which is installed on a heat generation body (20) to increase a heat conduction area with the heat generation body (20) for increasing a heating efficiency for the cooling water, guide the flowing direction of the cooling water circulated in the flowing water space unit (14), generate a vertical eddy current of the cooling water, and allowing the cooling water to be evenly heated by the heat generation body (20). The present invention is able to rapidly and evenly heat cooling water by the heat generation body (20) for increasing battery efficiency of an electric vehicle in winter, heat the battery within a short time by using the heated cooling water, use the heated cooling water for heating the indoors of the electric vehicle and for removing frost formed on a front surface glass, and increase battery efficiency of the electric vehicle.

    본 발명은 전기 자동차용 배터리의 냉각장치에 있어서, 전기 자동차용 배터리의 냉각장치에 있어서, 냉각수가 순환되는 몸체(10)가 구비되고, 상기 몸체(10)에는 몸체(10) 내부에 형성된 유수공간부(14)를 통해 냉각수가 순환되도록 하는 유입구(11)와 배출구(12)가 형성되며, 상기 유수공간부(14)에는 발열체(20)에 부착설치되어 냉각수의 가열효율을 높이기 위해 발열체(20)와의 열전도 면적을 증대시킴과 함께 유수공간부(14)에서 순환되는 냉각수의 흐름 방향을 안내하면서 냉각수의 상하 와류가 발생되도록 하여 발열체(20)에 의해 냉각수가 고르게 가열될 수 있도록 하는 유로부(30)가 구성되어 동절기에 전기 자동차의 배터리 효율을 높이기 위해 발열체(20)에 의해 냉각수를 빠르고 고르게 가열시킬 수 있는 효과가 있으며, 가열된 냉각수를 이용하여 배터리를 빠른시간 내에 가열시켜줌과 함께 가열된 냉각수를 전기 자동차의 실내 히팅 및 전면 유리의 성애를 제거하는데에 사용되도록 함으로써 전기 자동차의 배터리 효율을 증대시킬 수 있는 효과가 있다.
