Abstract
The utility model discloses a kind of exhaust pipe assemblies for compressor, including being located at the inner tube inside compressor and the outer tube outside compressor, the outer tube is copper pipe or copper-plated tube, and the be integrally formed nozzle of formula pipe fitting and inner tube of said inner tube is provided with bulge loop for welding with compressor housing；Outer tube is plugged on the nozzle of inner tube.By Design of Exhaust Manifold at fabricated structure, the inner tube inside compressor is made the utility model of the more cheap material of price, and the normal function of neither influence exhaust pipe can reduce the cost of entire exhaust pipe assembly again；Meanwhile the inner tube of exhaust pipe assembly is designed to the structure of variable cross-section by the utility model, and bulge loop is arranged on inner pipe, is conducive to realize projection welding between inner tube and compressor top cover.
Description
Technical field
The utility model relates to component of machine field more particularly to a kind of exhausts of the low cost for compressor of air conditioner
Tube assembly.
Background technique
Air condition compressor exhaust pipe is connect there are two types of mode with compressor top cover at present: the first is by a copper pipe and pressure
Contracting machine upper cover is connected by the way of ag-cu solder high frequency brazing；This connection type defect be using ag-cu solder price it is high
And high frequency brazing production efficiency is low.Second of improvement as the first exhaust pipe connection type, among exhaust pipe copper pipe
It is set with a steel ring, using brazing solder, exhaust pipe assembly is fabricated in a manner of gas brazing, then by the exhaust pipe assembly
Steel ring link together with compressor top cover projection welding.
No matter which kind of above-mentioned connection type is used, the exhaust pipe that the prior art uses is copper pipe, and the one of copper pipe
Part is located at outside compressor (this part with the copper pipe of air conditioner for connecting), and a part is located at the inside of compressor.It is based on
Exhaust pipe plays the role of within the compressor, and exhaust pipe, which stretches out compressor section, need to use copper pipe to meet the soldering of copper phosphorus to base material
Material requires and requirement for anticorrosion；But exhaust pipe protrudes into one section inside compressor then without specific materials requirement.Therefore, originally from drop
The considerations of angle of synergy, in conjunction with the high price of current metal copper pipe, the exhaust pipe of the prior art still has and reduces cost
Space.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of low-cost exhaust pipes for compressor of air conditioner
Component.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of exhaust pipe for compressor
Component, including being located at the inner tube inside compressor and the outer tube outside compressor, the outer tube is copper pipe or copper-plated tube, institute
State the be integrally formed nozzle of formula pipe fitting and inner tube of inner tube and be provided with bulge loop for welding with compressor housing, bulge loop it is straight
Diameter should be greater than diameter of inner pipe 4mm or more, and inner tube preferably uses cheap pipe fitting, such as steel pipe；Outer tube is plugged on the nozzle of inner tube.
Specifically, said inner tube is that tubing, outer tube and inner tube made of steel pipe or copper-steel composite material are brazed in splicing position；
The internal diameter of inner tube nozzle is greater than the internal diameter of inner tube pipe shaft.
The utility model has the advantages that (1) the utility model by Design of Exhaust Manifold at fabricated structure, the inner tube inside compressor is adopted
Be made of the more cheap material of price, neither influence exhaust pipe normal function again can reduce entire exhaust pipe assembly at
This；(2) inner tube of exhaust pipe assembly is designed to the structure of variable cross-section by the utility model, and bulge loop is arranged on inner pipe, is conducive to
Projection welding is realized between inner tube and compressor top cover.
Detailed description of the invention
Fig. 1 is the application state figure of 1 exhaust pipe assembly of embodiment.
Fig. 2 is the application state figure of 2 exhaust pipe assembly of embodiment.
Wherein: 1, outer tube；2, inner tube；21, bulge loop；3, compressor top cover.
Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As shown in Figure 1, the exhaust pipe assembly for compressor of the present embodiment, including being located at the inner tube 2 inside compressor
With the outer tube 1 being located at outside compressor, the outer tube 1 is copper pipe, and said inner tube 2 is steel pipe, and inner tube 2 is by the stamped technique of steel pipe
It is integrally formed；The nozzle of inner tube 2 is provided with the bulge loop 21 for welding with compressor housing, and the diameter of bulge loop 21 should be greater than inner tube
2 diameter 4mm or more, the welding surface of bulge loop 21 are 45 ° of inclined-planes；
Outer tube 1 is plugged on the nozzle of inner tube 2, and outer tube 1 and 2 splicing position of inner tube suit brazing solder ring (are also possible to other
High-temp solder ring), method of the outer tube 1 through gas brazing or furnace brazing and inner tube 2 form exhaust pipe assembly；
Wherein, the internal diameter of 2 nozzle of inner tube is greater than the internal diameter of 2 pipe shaft of inner tube, and the depth of inner tube 2 is inserted into convenient for control outer tube 1.
Fig. 1 is the application state figure of the present embodiment exhaust pipe assembly, and the exhaust pipe assembly of the present embodiment passes through when in use
Bulge loop 21 in inner tube 2 is welded in compressor top cover 3, although entire inner tube 2 is made of cheap steel pipe, due to interior
Pipe 2 is completely in inside compressor, and the normal function of neither influence exhaust pipe can reduce the cost of entire exhaust pipe assembly again.
Embodiment 2
As shown in Fig. 2, the present embodiment is substantially the same manner as Example 1, difference is only in that the present embodiment exhaust pipe group
The inner tube 2 of part is made of cold heading technique.
Although the embodiments of the present invention is illustrated in specification, these embodiments are intended only as mentioning
Show, should not limit the protection scope of the utility model.Various omissions are carried out in the range of not departing from the utility model aims, are set
It changes and change should be included in the protection scope of the utility model.
