The present invention aims to enhance durability, stability, and heat exchange performance of a cooling plate installed at a base of a batter pack as a battery heat exchanger of an electric vehicle, and to reduce manufacturing cost. The cooling plate according to the present invention comprises: a plate upper portion having a predetermined area on which a cooling object can be placed; a plate lower portion riveted to the plate upper portion; and a cooling closed circuit formed to cover at least a part of the predetermined area, supported by the plate lower portion, and accommodated by the combination of the plate upper portion and the plate lower portion. An inlet and an outlet of the cooling closed circuit are formed on the plate lower portion.

    본 발명은 전기 자동차의 배터리 열교환 장치로서 배터리 팩의 기저에 설치되는 냉각 플레이트의 내구성, 안정성 및 열교환 성능을 높이는 동시에 제조 단가를 절감하기 위한 것이다. 본 발명에 따른 냉각 플레이트는, 냉각 대상체가 안착될 수 있는 소정의 면적을 가진 플레이트 상부; 상기 플레이트 상부와 리벳 결합되는 플레이트 하부; 및 상기 소정의 면적의 적어도 일부를 커버하도록 형성된 냉각 폐회로로서, 상기 플레이트 하부에 의하여 지지되며 상기 플레이트 상부 및 상기 플레이트 하부의 결합에 의하여 격납되는 냉각 폐회로를 포함하며, 상기 플레이트 하부에 상기 냉각 폐회로의 입수부 및 출수부가 형성된다.
