The present invention relates to a seawater pump, and more specifically, to a seawater pump cooling system to cool down the seawater pump. According to the present invention, the seawater pump cooling system is to cool down an electric motor (2a) of a seawater pump system (2) installed on a flow path (1) for supplying seawater. The electric motor (2a) comprises a motor housing (340) in which a stator and a rotor of the electric motor (2a) are installed. According to the present invention, the seawater pump cooling system comprises: a cooling module (100) including: an air flow formation unit (110) which absorbs external air and forms an air flow to make the absorbed external air flow into the motor housing (340); and a cooling unit (120) installed on an air flow path (P) formed by the air flow formation unit (100) to cool down the air flowing along the air flow path (P) by cooling water flowing therein; and a cooling water cooling unit (200) installed together with the cooling unit (120) to make the cooling water circulate, which cools down the cooling water received from the cooling unit (120) and transfers the cooling water to the cooling unit (120). According to the present invention, the seawater pump cooling system is able to guarantee a stable operation of the seawater pump. 본 발명은, 해수펌프에 관한 것으로서, 보다 상세하게는 해수펌프를 냉각하기 위한 해수펌프 냉각시스템에 관한 것이다. 본 발명은, 해수공급을 위한 유로(1)에 설치되는 해수펌프시스템(2)의 전동기(2a)를 냉각하기 위한 해수펌프 냉각시스템으로서, 상기 전동기(2a)는, 내부에 상기 전동기(2a)의 고정자 및 회전자가 설치된 모터하우징(340)을 포함하며, 외부공기를 흡입하여 상기 모터하우징(340) 내부로 흐르도록 공기유동을 형성하는 공기유동형성부(110)와, 상기 공기유동형성부(100)에 의하여 형성되는 공기유로(P) 상에 설치되어 내부에 흐르는 냉각수에 의하여 공기를 상기 공기유로(P)를 따라서 흐르는 공기를 냉각하는 냉각부(120)를 포함하는 냉각모듈(100)과; 상기 냉각부(120)와 함께 냉각수가 순환하도록 설치되어 상기 냉각부(120)로부터 전달받은 냉각수를 냉각한 후 상기 냉각부(120)로 전달하는 냉각수냉각부(200)를 포함하는 것을 특징으로 하는 해수펌프 냉각시스템을 개시한다.
