Technical Field

[0001] The utility model belongs to the technical field of refrigeration, and in particular relates to a silent drying filter for a vehicle-mounted refrigerator refrigeration system, and specifically provides a drying filter with an elastic component disposed therein. Background Art

[0002] In the refrigeration system, the filter drier is mainly used to absorb moisture and filter impurities in the pipeline. It is usually installed between the condenser (low-pressure side) and the capillary tube (high-pressure side) in the refrigeration system.

[0003] Due to structural limitations, the molecular sieve in the prior art filter drier will collide between the inlet filter assembly and the outlet filter assembly during driving, generating noise, which is not suitable for vehicles with high requirements for quietness. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a silent drying filter which can effectively reduce the collision of molecular sieves.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a drying filter with an elastic component inside, characterized in that it includes an outer tube, the left end of the outer tube is an inlet end for connecting to the low-pressure side, the right end of the outer tube is an outlet end for connecting to the high-pressure side, the middle part of the outer tube is a molecular sieve filling space for loading molecular sieves, the left end of the molecular sieve filling space is provided with an inlet filter assembly, an elastic assembly, and a limiting molecular sieve filter assembly from left to right, and the right end of the molecular sieve filling space is provided with an outlet filter assembly.

[0006] Compared with the prior art, the advantages of the utility model are: this silent drying filter for car refrigerators has a simple structure, stable performance, high safety factor, and utilizes elastic components to reduce the movable space of the molecular sieve, thereby reducing the collision of the molecular sieve to achieve noise reduction effect, thereby being able to reduce the noise of the drying filter and having a good silent effect. It is suitable for use in various car refrigerators that have a silent product sound requirement. BRIEF DESCRIPTION OF THE DRAWINGS
