Plate fin type ice cold accumulator

A plate-fin type ice cold storage device belongs to the field of cold storage engineering, which comprises a cold storage tank, a cold storage medium, a replenishing pipe, an inlet seal head, an outlet seal head, a bracket, a drain pipe, a rear end seal head, a heat transfer cylinder, a medium outlet pipe connection and a medium inlet pipe connection, wherein the heat transfer cylinder is composed of straight porous rectangular fins, side seal strips and a flat partition board. A refrigerant or a secondary refrigerant is put in the heat transfer cylinder which is composed of the straight porous rectangular fins via the medium inlet pipe connection and then the refrigerant or the secondary refrigerant which transfers heat with the cold storage medium in the cold storage tank via the heat transfer cylinder flows out from the medium outlet pipe connection. Compared with traditional ice storage devices, the finned tube ice storage device not only greatly enlarges ice-making area or ice-melting area, reduces addit
