A connection structure between an air delivery pipe and a connecting hole of an upper cover of the traditional separator is shed off due to vibration in the running process of the automobile. The utility model makes improvement on the connection structure. The utility model comprises the upper cover, a flow guide cover, the air delivery pipe, a lower body, a drying bag and a filter net, wherein the upper cover is combined with the lower body, and the flow guide cover, the air delivery pipe, the drying bag and the filter net are positioned in the lower body. One end of the air delivery pipe is connected with an air outlet which is arranged on the upper cover, and an opening of the other end is arranged on the flow guide cover. The utility model is characterized in that an undercutting groove is arranged in a connecting hole; after the air delivery pipe is positioned in the connecting hole, technology of an expanding pipe is used, and the outer wall of the air delivery pipe forms an annularly convex groove; the annularly convex groove is embedded in the undercutting groove of the connecting hole.
Description
Technical field
The utility model specifically, relates to the improvement of liquid-gas separator in the automotive air-conditioning system relevant for automotive air-conditioning system.
Background technology
Liquid-gas separator is parts between evaporimeter and compressor, and it is in order to guarantee that the liquid refrigerant in the cold-producing medium separates, to use to offer the compressor machine.
Fig. 1 shows the structural representation of traditional liquid-gas separator, and it comprises loam cake 1, kuppe 2, appendix 3, lower body 4, dry bag 5 and filter screen 6.Loam cake 1 combines with lower body 4, forms the profile of separator.Kuppe 2, appendix 3, dry bag 5 and filter screen 6 are positioned at lower body 4.One end of appendix 3 is connected the gas outlet 7 on the loam cake 1, and other end opening is in kuppe 2.Cold-producing medium enters in the liquid-gas separator from air inlet 8, through the outside passages that form with lower body 4 of kuppe 2 dry bag of flowing through, reaches the rise opening of the appendix 3 through being positioned at kuppe inside of back, liquid-gas separator bottom and enters appendix 3,7 outputs from the gas outlet at last.After cold-producing medium enters from air inlet 8, until gas outlet 7, need long flow process, help the separation of the liquid refrigerant in the cold-producing medium of gas-liquid mixed.Because air-conditioning system is to be applied on the automobile, therefore, must be able to bear the various vibrations in the vehicle movement process.In liquid-gas separator, appendix 3 is a weak link with being tightly connected of loam cake 1.
See also shown in Figure 2, Fig. 2 show appendix 3 and on syndeton between the gas outlet 7 that covers.Appendix 3 connects by the connecting hole on loam cake 19.Traditional method of attachment is that taper shape is processed in the coupling part of appendix 3, on the connecting hole 9 that covers also be processed into corresponding taper shape, its cone angle is less than 5 degree.The cone angle that connects by both is less than cone of friction, both are fitted tightly and is connected securely.Yet, owing to reasons such as processing, defeated unload the cone angle of pipe 3 and there is tolerance in the cone angle of connecting hole 9, add oval influence, actual faying face only accounts for the part of taper seat, causes in conjunction with reliability not high.Vibration often caused to connect and lost efficacy during vehicle travelled, and appendix 3 is come off from the connecting hole 9 of loam cake 1, and liquid cryogen directly enters gas outlet 7 from air inlet 8, forms short circuit, causes liquid-gas separator to lose efficacy.
The utility model content
Based on the problem that exists in the above-mentioned background technology, the purpose of this utility model is to provide a kind of connected mode through improved liquid-gas separator, and this improvement has improved the performance that is tightly connected between the appendix 3 and connecting hole 9 in the liquid-gas separator.According to above-mentioned purpose, liquid-gas separator of the present utility model comprises: loam cake, kuppe, appendix, lower body, dry bag and filter screen, described loam cake combines with described lower body, described kuppe, described appendix, described dry bag and described filter screen are positioned at described lower body, one end of described appendix is connected the gas outlet that covers on described, other end opening is in described kuppe, it is characterized in that, in the described connecting hole undercut groove is arranged, after described appendix navigates in the described connecting hole, adopt expansion tube process, form the ring-type tongue on the outer wall of appendix, described ring-type tongue is embedded in the undercut groove of described connecting hole.
Description of drawings
Fig. 1 is the structural representation of traditional liquid-gas separator;
Fig. 2 is the johning knot composition between appendix and the loam cake connecting hole among Fig. 1;
Fig. 3 is the johning knot composition between appendix and the loam cake connecting hole in the liquid-gas separator of the present utility model.
The specific embodiment
Overall structure of the present utility model is identical with traditional liquid-gas separator, can be with reference to the structure chart of the description in the background technology and Fig. 1.Improvements of the present utility model are the syndeton between appendix and the loam cake connecting hole.
See also Fig. 3, Fig. 3 shows the syndeton between the connecting hole 39 on efferent duct 33 and the loam cake 31.Appendix 33 and connecting hole 39 needn't adopt traditional conical structure.Binding site at connecting hole 39 and appendix 33 processes undercut groove 30, then appendix 3 is navigated in the loam cake connecting hole, adopt expansion tube process, telogenesis ring-type tongue 31 on the outer wall of appendix 33 is embedded in the undercut groove 30 of connecting hole ring-type tongue 31.So can improve greatly between the two in conjunction with moment of torsion, guarantee closely fixing between the two to have improved the ability of anti-vibration.
Quantity for the undercut groove of processing is chosen between the 1-4 bar usually, and preferable quantity is the 2-3 bar.Width and interval for undercut groove.Preferably between 1-1.5mm, the interval between groove and the groove preferably is 1-1.5mm to the width of undercut groove.The degree of depth of undercut groove can be decided according to the material that appendix is selected for use, and as No. 1200 seamless aluminium tubings of appendix material selection, the degree of depth preferred values of undercut groove is 0.5mm; No. 3003 seamless aluminium tubings of appendix material selection, the degree of depth preferred values of undercut groove is 0.3mm.
After tested, adopt the integrated structure of above-mentioned appendix of the present utility model and connecting hole, it turns round weak point can reach 10N.m, is higher than traditional structure.
