A leak check device according to the present invention comprises: a lower fixing plate (10) for fixing a thermal management device (50) so that the inside is sealed in an upside down state; an upper pressurizing device (20) which pressurizes the thermal management device (50) from the top in a state in which the thermal management device (50) is fixed to the lower fixing plate (10) so that the sealing by the lower fixing plate (10) is firmly maintained while preventing the thermal management device (50) from moving; and a sealing device (30) which seals an inlet (51) and an outlet (52) of the thermal management device (50) having the inside sealed and fixed by the lower fixing plate (10) and the upper pressurizing device (20), and introduces and discharges air through the inlet (51) to check the sealing state of the thermal management device (50) through a change in the amount of air introduced and discharged. Therefore, leaks in the battery thermal management device for an electric vehicle can be automatically checked, such that a product defect can be checked prior to installation.

    본 발명은 리크검사장치에 있어서, 열관리 장치(50)를 뒤집어 놓은 상태로 내부가 밀폐되도록 고정시키는 하부고정판(10)과, 열관리 장치(50)가 하부고정판(10)에 고정된 상태에서 상부에서 가압하여 열관리 장치(50)가 움직이지 않도록 하면서 하부고정판(10)에 의한 밀폐가 견고하게 유지되도록 하는 상부가압장치(20)와, 하부고정판(10)과 상부가압장치(20)에 의해 내부가 밀폐되어 고정된 열관리 장치(50)의 유입구(51)와 배출구(52)를 밀폐하고 유입구(51)를 통해 에어를 유입, 배출시켜 유입, 배출되는 에어의 양의 변화를 통해 열관리 장치(50)의 밀폐상태를 확인하도록 하는 밀폐장치(30)로 구성되어 전기자동차용 배터리 열관리 장치의 누수를 자동으로 검사할 수 있어 설치전에 제품불량유무를 확인할 수 있는 효과가 있다.
