The present invention provides a cooling device for a polar area ship which is applied to a ship traveling in a polar area and realizes introduction and discharge of sea water used for cooling down a main engine portion using natural convection, such that an economical interest is maximized by saving energy and simplifying a structure, and a cooling efficiency of sea water is maximized. The cooling device for a polar area ship comprises: a chamber (7) which is arranged on a portion of a ship (2) which is immersed in sea water, contains the sea water, and includes an inlet hole (5), through which the sea water is introduced, and an outlet hole (6) through which the sea water is discharged; and a heat exchanger (10) which is arranged in the chamber (7) in a space between the inlet hole (5) and the outlet hole (6), includes an introduction hole (8), through which refrigerant is introduced from a circulation tube (4) circulating to cool down a heat source of the ship, and an ejection hole (9), through which the refrigerant is ejected to the circulation tube (4), and enables a heat exchange between the sea water, which flows from the inlet hole (5) to the outlet hole (6), and the refrigerant. In the chamber (7), the outlet hole (6) is arranged at a position which is higher in a vertical direction than the inlet hole (5). In the heat exchanger (10), the ejection hole (9) is arranged at a position which is closer to the inlet hole (5) than the introduction hole (8).

    본 발명은, 극지를 운행하는 선박에 적용되어 주기관 부의 냉각에 사용되는 해수의 유입 및 배출이 자연 대류를 통해 구현되도록 함으로써, 에너지의 효율적인 절감과 구조적 단순화를 통한 경제적 이익을 극대화할 수 있으며, 해수의 냉각효율을 증대할 수 있도록,선박(2)에서 해수에 잠기는 부위에 마련되며 해수가 유입되는 입구(5)와 배출되는 출구(6)를 가지는 해수가 수용되는 챔버(7)와, 상기 챔버(7)에서 상기 입구(5)와 출구(6)의 사이 공간에 배치되며 선박의 열원을 냉각하도록 순환하는 순환 관(4)에서 냉매를 유입하는 유입구(8)와 상기 순환 관(4)으로 냉매를 토출하도록 된 토출구(9)를 가지며 상기 입구(5)에서 상기 출구(6)로 이동하는 해수와 냉매가 열교환하도록 하는 열교환기(10)를 포함하여 이루어지며; 상기 챔버(7)에서, 상기 출구(6)는 상기 입구(5)보다 수직 상 그 높이가 높은 위치에 배치되고; 상기 열교환기(10)에서, 상기 토출구(9)는 상기 유입구(8)보다 상기 입구(5)에 더 근접된 위치에 위치되도록 배치되는 극지용 선박의 냉각장치를 제공한다.
