Description

Technical Field

[0001] The utility model relates to the technical field of cold storage refrigeration, in particular to a refrigeration fin assembly for a cold storage refrigeration system. Background Art

[0002] A cold storage is a facility that uses a refrigeration system to create a low-temperature environment indoors and stores materials in a low-temperature environment. It is widely used in industries such as logistics, warehousing, food and drug manufacturing, etc. A refrigeration system is usually composed of a refrigerant, a compressor, a condenser, an expansion valve, an evaporator and other components, wherein the compressor, the condenser, the expansion valve and the evaporator are connected by a circulation pipeline, and the refrigerant circulates in the circulation pipeline, wherein the evaporator is located in the cold storage, and the part of the circulation pipeline located in the evaporator is a refrigerant pipe. A fin assembly with multiple refrigeration fins is also provided in the evaporator, and the refrigerant in the refrigerant pipe evaporates and absorbs heat in the evaporator to cool, and the refrigeration fins dissipate the cold air generated by the refrigeration to reduce the temperature in the cold storage. Since the refrigerant pipe and the refrigeration fins are in a low temperature state, frost is likely to appear on the refrigeration fins. The refrigeration (heat dissipation) and frosting of the refrigeration fins are highly correlated with the spacing of the refrigeration fins. The smaller the spacing of the refrigeration fins, the better the refrigeration effect of the refrigeration fins, but the water vapor in the cold storage is more likely to adhere to frost, and the frosting process usually starts from the edge of the refrigeration fin (the water vapor in the cold storage gathers from the outside to the inside on the refrigeration fins). Therefore, it is difficult for the evaporator fin assembly of the existing cold storage refrigeration system to simultaneously improve its refrigeration characteristics and the effect of inhibiting frost.
