According to an aspect of the present invention, a battery pack includes: a plurality of battery modules; a tray for providing a space in which the plurality of battery modules are placed; a plurality of beam frames installed across the upper surface of the tray and defining a space in which the plurality of battery modules can be individually placed; and a plurality of heat sinks which have a hollow structure for moving cooling water and are selectively coupled to some of the plurality of beam frames, respectively. Drain holes which are perforated in a downward direction with respect to each of the heat sinks are provided in the tray and the beam frame. The battery pack has sufficient durability against external shock and vibration.

    본 발명의 일 측면에 따른 배터리 팩은, 다수의 배터리 모듈; 상기 다수의 배터리 모듈들이 놓이는 공간을 제공하는 트레이; 상기 트레이의 상면을 가로지르도록 설치되어 상기 다수의 배터리 모듈들이 개별적으로 놓일 수 있는 공간을 구획하는 다수의 빔 프레임; 및 냉각수가 유동할 수 있는 중공 구조로 형성되며, 각각의 상기 배터리 모듈의 측면부에 대향하게 배치되도록 각각 상기 다수의 빔 프레임들 중 일부와 선택적으로 결합되는 다수의 히트싱크를 포함하며, 상기 트레이와 상기 빔 프레임에는 각각의 상기 히트싱크에 대해 하부 방향으로 천공된 형태의 배수구가 마련되는 것을 특징으로 한다.
