Description
Technical field
This utility model belongs to compression machine part field, more particularly, it relates to a kind of air inlet modified model air conditioning liquid reservoir.
Background technology
Reservoir is the vitals of compressor, is typically fitted in vaporizer and the compressor suction duct position of air-conditioning, is prevented
Only liquid refrigerant flows into compressor city and produces liquid hit phenomenon.Reservoir includes air inlet pipe, cylinder and escape pipe, and air inlet pipe is general
It is connected with solenoid directional control valve interface, escape pipe is connected to compressor interface.Entered by air inlet pipe from vaporizer cold-producing medium out and stored up
Liquid device, liquid refrigerant state itself fall directly into a bottom, and gas refrigerant are sucked in compressor from escape pipe than gas weight,
To prevent compressor suction liquid refrigerant from causing liquid hammer, the effect of gas-liquid separation has been thereby served to.
In current air conditioning liquid reservoir, cylinder adopts steel pipe, air inlet pipe and escape pipe to form using copper pipe processing, air inlet pipe
Typically it is attached using brazing mode and escape pipe and cylinder between.Because soldering is to compare mother metal using liquidus temperature (fusing point)
The low metal material of solid-state temperature as solder, by part and solder heat to brazing filler metal melts, using liquid solder moistening mother metal,
Filling play movement the method for being mutually dissolved with mother metal and spreading and realize union piece.Due to the heat transfer temperature of different mother metals
Difference, so the problems such as solder bad, surface oxidation of infiltration is also easy to produce after welding, causes between air inlet pipe, escape pipe and cylinder
Failure welding, so the slip of reservoir is higher always, product person is measured less than reliable guarantee, meanwhile, air inlet pipe and
Escape pipe all adopts copper, and manufacturing cost is higher.And the welding manner of soldering, not only efficiency is low, long processing time.
Have tried to all adopt the steel pipe, such as Chinese Patent Application No. to be the cylinder of reservoir, air inlet pipe and escape pipe：
200920036722.7, publication date is：The patent documentation on January 27th, 2010, discloses a kind of air conditioning liquid reservoir, including air inlet
Pipe, cylinder and escape pipe, cylinder include upper shell and lower shell, and air inlet pipe is a straight tube, and its one end is connected on upper shell,
The other end stretches out upper shell；One end of escape pipe is connected to lower shell bottom, and the other end stretches out lower shell, end bending；Top cylinder
Body is mutually socketed with lower shell, and upper shell, lower shell, air inlet pipe and escape pipe are made using Steel material, described air inlet pipe with
Connected using soldering connection, CO2 protection weldering connections or an argon arc welding in stove between upper shell, between escape pipe and lower shell
Connect.But, it is copper material that the connection of reservoir and other parts necessarily requires the connection end of air inlet pipe and escape pipe, using steel
Material cannot connect at all, program air inlet pipe and escape pipe using steel matter be in actual use all it is hardly possible,
Cannot realize.
The present inventor is based on the problems referred to above, tries to be improved, and has applied for patent before this, the application number of the patent
For：201220536225.5, publication date is：On March 27th, 2013, a kind of reservoir with convex tendon is disclosed, it includes feed liquor
Pipe, drainage screen, cylinder and drain pipe, also including inner tube, described feed tube is connected with the porch of cylinder, with cylinder on feed tube
There is first convex tendon parallel with feed tube axial direction one end of body connection；Described drainage screen is located at the inside of cylinder；It is described
Inner tube be located at cylinder inside and one end be connected with the exit of cylinder；One end of described drain pipe is also gone out with cylinder
Connect at mouthful, junction is followed successively by cylinder, inner tube and drain pipe from outermost layer to innermost layer, the one end being connected with cylinder in inner tube
There is second convex tendon parallel with inner tube axial direction.Although the scheme of this application has changed to connection reliability to a certain extent
It is kind, but brazing mode is still adopted, bonding strength is also less desirable, and welding slag can be entered in cylinder, needed cleaning, operated numerous
It is trivial, and air inlet pipe is full copper, production cost is high, and soldering efficiency is low, and the application is the further improvement based on this scheme, makes every effort to energy
It is enough preferably to solve the above problems.
The content of the invention
