Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, and object is to help those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contributes to its enforcement.
If Fig. 1 is to scheming as shown in X, a kind of gs-oil separator for automotive air-conditioning system of the present invention, comprise housing, the upper and lower end of housing is respectively equipped with liquid inlet joint 3 and the back leakage connection 4 for being connected with pipeline, housing sidepiece is provided with fluid joint 5, is provided with the through hole and through hole and the gs-oil separator internal communication that allow medium pass through as refrigerant, refrigerator wet goods in liquid inlet joint 3, back leakage connection 4 and fluid joint 5.Enclosure interior is provided with filter and oil return capillary 6, and filter is positioned at the below of liquid inlet joint 3, and capillary is as oil return apparatus, is positioned at the below of filter and is positioned at the inner bottom part of housing.Liquid inlet joint 3 is connected with the outlet of compressor by pipeline, in the refrigerant that compressor is discharged, contain a large amount of refrigerator oils along with refrigerant enters in gs-oil separator, back leakage connection 4 is connected with the crankcase of compressor by pipeline, and the refrigerator oil filtering out in gs-oil separator flows out in pipeline enters the crankcase of compressor from back leakage connection 4.Fluid joint 5 is connected with condenser by pipeline, after filtering in gs-oil separator, does not contain refrigerator oil in refrigerant, and the refrigerant in gs-oil separator flows out through pipeline air-inlet condenser from fluid joint 5.
In order to solve problems of the prior art, the housing of this gs-oil separator is to be connected and composed by upper and lower two parts.
Specifically, housing is divided into upper shell 1 and lower shell 2, upper shell 1 and lower shell 2 are by plate stretch moulding and have the cylindrical tubular structure of an end opening, inner hollow, be the ST16 deep drawn sheet material of stretching good-extensibility for the sheet material of making upper shell 1 and lower shell 2, processing and fabricating is convenient, simple, can make housing design become 2 segmentations, only need upper and lower two parts to form, housing overall volume is less, thereby also just can reduce the volume of gs-oil separator, take up room little, so that the layout on vehicle.The length of the housing that upper shell 1 and lower shell 2 are connected to form is 104mm, and the diameter of main part is 76.2mm, and volume is little.
The lower end of upper shell 1 is circular openend, and the upper end of lower shell 2 is circular openend, and upper shell 1 and lower shell 2 are welded to connect integral in open end by CO2 gas shielded arc welding.Liquid inlet joint 3 is inserted in the flanging bore of upper end center position setting of upper shell 1, and be fixed on upper shell 1 by the mode of soldering, back leakage connection 4 inserts in the flanging bore of lower end center position setting of lower shell 2, and is fixed on lower shell 2 by the mode of soldering.
As shown in the figure, the openend of lower shell 2 is to insert the necking end being connected with upper shell 1 in the openend of upper shell 1, the external diameter of the openend of lower shell 2 is little compared with the external diameter at other positions, between the outer wall of openend and bottom outer wall, form step surface, after inserting upper shell 1, position, so that welding processing.
As preferably, one-level filter screen 7 is that the string diameter that adopts high-strength stainless steel to make is that 0.1mm, order number are that 50 objects are shaped as annular screen pack, secondary filter screen 8 be with the string diameter that high-strength stainless steel is made be that 0.05mm, order number are 80 object sheet screen packs.This gs-oil separator adopts two screen packs, forms multiple filtration system, carries out twice filtration to entering inner refrigerant and refrigerator oil, removes residual impurity, impels the refrigeration oil purity of getting back to compressor greatly to improve.
As shown in the figure, be also provided with a deflector 9 in upper shell 1 inside, deflector 9 is positioned at the sidepiece of the first filter, and between the first filter and the arrival end of fluid joint 5.Being shaped as of this deflector 9 is L shaped, the transverse slat lower surface of its lower end contacts with the upper surface of secondary filter screen 8, its stringer board is vertical with secondary filter screen 8 and vertical with the axis of fluid joint 5, the two sides of deflector 9 contact with the internal face of upper shell 1, deflector 9 is welded to connect in two sides and upper shell 1, realizes the fixed installation in upper shell 1.The stringer board of deflector 9 is near the first filter, upper shell 1 inner chamber is isolated into two spaces by deflector 9, after the first filter filters, at refrigerant in fluid joint 5 place direction flow process, the refrigerator oil carrying in refrigerant can stick on deflector 9, and along deflector 9 towards current downflow, pass through again the filtration of secondary filter screen 8, finally flow to the bottom of lower shell 2, therefore, deflector 9 has refrigerant and refrigerator oil is carried out to the effect of separating and condensing again, greatly improves with the separation rate that impels gs-oil separator.
The oil return capillary 6 of lower shell 2 bottoms is as oil return apparatus, the arrival end of oil return capillary 6 is downwards towards the bottom of lower shell 2, in order to suck refrigerator oil, the port of export of oil return capillary 6 inserts in back leakage connection 4, in order to discharge refrigerator oil, oil return capillary 6 can play the effect of cold and hot exchange, to improve the operational efficiency of air-conditioning system.Due to oil return capillary 6 around external diameter slightly larger than the internal diameter of lower shell 2, to be press fit in lower shell 2 by equipment when mounted, substantially be close-fitting structure, oil return capillary 6 and lower shell 2 fixing with 3 of solderings, and the port of export of oil return capillary 6 inserts in back leakage connection 4 and is fixed by the mode of soldering.As preferably, the diameter of oil return capillary 6 is 2.3mm, along the internal face of lower shell 2 around 13 circles.
This gs-oil separator adopts said structure, and Oil-gas Separation rate is higher by 50% than common oil content, and contaminant filter effect is higher by 50% than common oil content, makes air conditioning energy consumption reduce by 30%, effectively improves the cooling or heating effect of automotive air-conditioning system.
It is all vertically orientation upward as benchmark definition, to should be appreciated that the use of the described noun of locality should not limit the scope of the application's request protection taking the liquid inlet joint 3 of gs-oil separator that related upper and lower of foregoing waited the noun of locality.
Below by reference to the accompanying drawings the present invention is exemplarily described.Obviously, specific implementation of the present invention is not subject to the restrictions described above.As long as having adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or without improvement, above-mentioned design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
