Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning liquid storage dryer devices, in particular to a lightweight automobile air-conditioning liquid storage dryer. Background Art

[0002] Automobile air conditioning systems are equipped with a receiver-drier to remove moisture and impurities from the system to ensure stable operation. Existing receiver-driers primarily consist of a housing, a filter assembly, a drying assembly, and input and output ports. The filter and drying assemblies are located within the housing, while the input and output ports are located on the housing. The housing is typically a sealed container in the shape of a cylinder or tank. After a certain period of use, the molecular sieve in the drying assembly loses its moisture absorption efficiency, necessitating regular replacement of the entire receiver-drier.

[0003] The existing air conditioning liquid storage and drying device has multiple sets of structural parts inside, which makes the device heavy. When installing, the strength of the external structural parts is required to be high. In addition, the existing automobile liquid storage and drying device is sealed when in use, which makes it inconvenient for the staff to disassemble it, clean or replace the internal filter layer, making it inconvenient for the staff to maintain and use it.
