Description
Technical field
The present invention relates to a kind of connection structure, more particularly to a kind of mini air conditioner compressor inleting pipe connect knot with rack
Structure.
Background technology
Mini air conditioner compressor is a kind of pollution-free environment-friendly air conditioner compressor, it is suitable for small-scale refrigeration cool-down ring
Border, such as unattended moving machine station, substation, new-energy automobile etc., this mini air conditioner compressor wide market, at present this
The air inlet pipe of kind micro-compressor is directly welded on gas brazing technique in rack using copper pipe, its weld seam gas is found in production
Close property is poor, and leak rate is high, and stacked solder, in frame surface, complete machine air inlet pipe weld seam leak rate is up to hundreds of PPM.Air inlet pipe is straight
Soldering, which is connect, generating the main reason for airtight bad in rack is:The coefficient of thermal expansion of copper pipe is swollen much larger than the heat of mild steel rack
Swollen coefficient, and the temperature of gas brazing is up to 800 degree or more, when welding the thermal expansion of high temperature copper pipe make between copper pipe and steelframe hole
Gap becomes smaller, and whole gaps are difficultly flowed into after brazing filler metal melts, so that the residual thermal stress of copper pipe is much larger than steel machine in cooling procedure
The thermal stress of frame, therefore gap can be widened in the contraction process of copper pipe, during solder doubts solid, solder is mixed in solid-liquid
Conjunction state, for the solder in gap under the action of by copper pipe residual thermal stress, solder will present loose shape in cooling procedure
State, or even crackle is formed by drawing crack, weld seam leak rate is inevitable very high, and micro-compressor reliability reduces, and qualification rate reduces, cost
Increase.
Invention content
The purpose of the present invention is to provide a kind of mini air conditioner compressor inleting pipe and frame connecting structures.
The technical solution adopted by the present invention is：
A kind of mini air conditioner compressor inleting pipe and frame connecting structure, it is characterised in that：Including rack, air inlet tube assembly, institute
It states and is provided with stomata in rack, the stomata is cylindrical hole for one section on the inside of rack, and one section is bellmouth, the machine in shell outside
Air inlet pipe component is installed, the air inlet tube assembly includes mild steel flange seat ring, phosphorous deoxidize copper tube, the low-carbon in the stomata of frame
Steel flange seat ring is mutually embedded with stomata to be set, and the phosphorous deoxidize copper tube is set in mild steel flange seat ring.
It is cylindricality circle that one section of the cylindrical hole of the mild steel flange seat ring and stomata, which matches, the bellmouth one with stomata
It is taper ring that section, which matches, and phosphorous deoxidize copper tube is installed in the tube-shaped through hole in the mild steel flange seat ring.
The air inlet tube assembly is press-fitted using mild steel flange seat ring and phosphorous deoxidize copper tube, and solder ring is preset at weld seam
Place, then by gas shield automatic brazing stove be brazed.
The air inlet tube assembly is by the pressure welding of intermediate frequency press welder in the stomata of rack.
Advantages of the present invention：Air-tightness is improved, micro-compressor air inlet pipe weld seam leak rate is reduced, improves yield rate, is protected
The safety that mini air conditioner compressor uses has been demonstrate,proved, more environmentally-friendly, the part after pressure welding does not have to scaling powder, is not necessarily to chemical cleaning,
A full set of sewage disposal device and expense have been saved, has been greatly improved than original gas brazing production efficiency, one part of pressure welding only needs
Several seconds, cost is greatly saved.
