Specifically, as shown in fig. 2-4, guide posts 31 are respectively disposed on both sides of the aluminum casing 32, and the fins 23 are provided with guide grooves 5 engaged with the guide posts 31, so that the ice-accumulating balls 3 can move up and down along the guide grooves 5 and are confined between the upper and lower adjacent straight tubes 21. According to the structure, the ice storage balls 3 can only move up and down along the guide grooves 5 and are limited between the upper straight pipe 21 and the lower straight pipe 21, so that the ice storage balls 3 are uniformly distributed in the cold storage ice tank 1, and the cold storage ice tank 1 is uniform in whole cold storage.
As shown in the figure, the cross section of the guide post 31 is square, so that the ice-storage balls 3 can be prevented from overturning compared with the cylindrical guide post 31, and the elastic rubber seal 33 is always arranged above the aluminum shell 32.
Further, as shown in FIG. 4, ice bank 3 includes an aluminum shell 32 and an elastic rubber seal 33. The top of the aluminum shell 32 is provided with an opening, and the opening is sealed by the elastic rubber seal 33, so that the aluminum shell 32 and the elastic rubber seal 33 form a closed space, and the closed space is filled with an aqueous medium. Further, as shown in fig. 2 and 4, an aluminum seat 4 is fixed below the ice storage ball 3, and the bottom of the aluminum seat 4 is provided with a cambered surface which is attached to the upper surface of the straight pipe 21.
