The present invention relates to a cooling apparatus for a low temperature storage, in which a coolant cooled by an outdoor cooler (10) is circulated along a water curtain (24) fixedly provided around an inner upper portion of a low temperature storage (12) through a coolant tank (18) so as to generate cool air through heat exchange with indoor air. Inlet portions (28, 30) and outlet portions (32, 34) of a circulation pipe (16) of the cooler (10) and a cooling pipe (22) of the water curtain (24) are formed to be connected at both sides of a bottom portion of the coolant tank (18) with a diaphragm (26) therebetween formed at an inner bottom portion of the coolant tank (18) so as to prevent moisture loss of stored goods due to indoor moisture reduction in the process of the heat exchange of the coolant, thereby keeping the stored goods fresh for a long time and preventing deterioration of a cooling function due to air infiltration into the coolant. 본 발명은 저온저장고용 냉각장치에 관한 것으로, 실외의 냉각기(10)에 의해 냉각된 냉매가 냉매탱크(18)를 통하여 저온저장고(12)의 내측상부에 빙둘러서 고정설치된 워터커튼(24)을 순환하면서 실내공기와의 열교환으로 냉기가 생성되게 하되, 냉각기(10)의 순환파이프(16)와 워터커튼(24)의 냉각파이프(22)가 갖는 입구부(28)(30)와 출구부(32)(34)는 냉매탱크(18)의 내측저부에 갖는 격판(26)을 사이에 두고 냉매탱크(18)의 저부양측에 연결형성하여 냉매의 열교환과정에서 실내수분감소로 인한 저장물의 수분손실을 방지하여 저장물을 장기간 신선하게 저장해줄 수 있도록 하고 또 냉매 내 에어침투에 의한 냉각기능저하를 방지해줄 수 있도록 한 것이다.
