Description

Technical Field

[0001] The utility model relates to the technical field of drying filters, in particular to an aluminum drying filter for a refrigeration system. Background Art

[0002] The dry filter filters the air in the refrigeration system to prevent the refrigeration system from inhaling air containing impurities and moisture, which may have a negative impact on the normal operation of the refrigeration system or cause damage to the refrigeration system. For example, a refrigeration system dry filter (patent number: CN202321421736.7) disclosed in Chinese patent literature has filter screens at both ends of the cylinder, and the end covers at both ends of the cylinder are fixed. There is no structure for quickly disassembling or installing the end covers at both ends of the cylinder. The disassembly of the end covers at both ends of the cylinder requires the same operation to be performed twice, resulting in a long disassembly time, which affects the efficiency of replacing the filter screen. The cylinder is filled with desiccant. To replace the desiccant, the desiccant in the cylinder needs to be cleaned before replacement, which further reduces the replacement of the filter screen and the desiccant.
