Automotive air conditioning system and liquid reservoir of automotive air conditioning system

Abstract

The invention discloses a liquid reservoir of an automotive air conditioning system, which comprises a liquid absorption pipe (11) arranged in a liquid reservoir. An absorption port of the liquid absorption pipe (11) is provided with a filtering part (12) used for filtering medium which enters the inner part of the liquid absorption pipe (11), a cavity which is communicated with the liquid absorption pipe (11) is enclosed by the peripheral wall of the filtering part (12), and a plurality of channels which are communicated with the cavity and the medium arranged in the liquid reservoir are arranged on the peripheral wall. The filtering part (12) in the liquid reservoir is arranged at the bottom of the liquid absorption pipe (11), the filtering area is large, and the flow area of the mediumpassing through the filtering part (12) is correspondingly large, so that the filter accuracy of the medium is enhanced, the work environment of the corresponding parts of the air conditioning systemis improved, and good flow capacity of the medium is also ensured without influencing the cooling effect of the automotive air conditioning system. In addition, the invention also discloses the automotive air conditioning system comprising the liquid reservoir.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning systems, in particular to a liquid reservoir of the automobile air-conditioning system. Furthermore, the present invention also relates to an automobile air conditioning system comprising the above-mentioned liquid reservoir. Background technique [0002] The liquid receiver is one of the important accessories in the automobile air conditioning system, and its main function is to store the medium, filter impurities and absorb water. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a liquid reservoir of a typical automotive air-conditioning system in the prior art. [0004] In the prior art, a typical liquid reservoir for automobile air-conditioning system includes a head 1 and a shell 2 welded to the head 1, and the two are welded to form a closed body except for the inlet 3 of the medium and the outlet 4 of the medium. container. The me...

AI Technical Summary

Problems solved by technology

[0006] The filtration accuracy of the liquid reservoir depends on the non-woven filter 7. When the flow capacity of the non-woven filter 7 is good, that is, the flow resistance is low, the filtration accuracy is poor, so that impurities with relatively large particles can easily pass through the filter. , into other parts of the air-conditioning system, causing pollution and increasing the wear and tear of parts, and may even cause blockage, affecting the normal operation of the air-conditioning system

[0007] Although improving the production process of non-woven fabrics and increasing the thickness of the material can improve the filtration accuracy, the cross-sectional area of ​​the liquid reservoir is certain, so the filter area of ​​the medium flowing through the non-woven fabric filter is certain. The higher the precision of the filter screen, the greater its resistance, and the poorer the flow capacity of the corresponding medium, especially for the liquid receiver with a smaller shaft diameter of the housing of the liquid receiver (that is, the smaller diameter of the filter piece), which is It will seriously reduce the cooling capacity of the air conditioning system
