Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
Referring to Fig. 1 to Fig. 5, shown in a kind of car air-conditioner pipeline structure, connect including one end with compressor air-discharging end
The second segment aluminum pipe 5 that first segment aluminum pipe 1, one end and refrigerating module connect, it is characterized in that: in the first segment aluminum pipe 1 and second
Muffler 2, rubber hose 3 are successively arranged between section aluminum pipe (5)；The muffler 2 by columnar ontology 20, be located at ontology circle
Air inlet pipe 21 in cambered surface is constituted with the escape pipe 22 being located on ontology end face, the other end of the first segment aluminum pipe 1 and noise reduction
The air inlet pipe 21 of device 2 is connected, and the escape pipe (22) of the muffler 2 is connected with one end of rubber hose 3, the rubber hose 3
The other end be connected with the other end of the second segment aluminum pipe 5.Increasing silencer is the fluid pulsation in order to reduce pipeline, is avoided
Fluid excites pipeline vibration.
The muffler 2 is interpolation pipe expansion muffler, the center line of air inlet pipe 21 and the center line of escape pipe 22
Vertically, whole L-shaped.
Damping mass set 4 is equipped in the rubber hose 3, damping mass set 4 is close to the another of the second segment aluminum pipe 5
One end.It is to reduce pipeline intrinsic frequency that damping mass set, which is arranged,.
The tube wall of the rubber hose 3 is layer structure, is followed successively by the first rubber layer 31, braiding layer 32, the from outside to inside
Two rubber layers 33 and nylon layer 34.The structure of the rubber hose has obvious effect to pipeline dynamic stiffness is reduced, and is conducive to absorb, decline
Subtract transmitting of the pipeline to body vibrations.The damping mass set 4 is by metal body 40, the outer rubber being located on metal body outer wall
Layer 41 and the inner rubber layer 42 being located on metal body inner wall are constituted.
The length of the rubber hose 3 is greater than 350mm.It is to reduce that the length requirement of the rubber hose, which is greater than 350mm,
Air-conditioning duct vibration transmissibility promotes the vibration transfer performance of air-conditioning duct, increases effectiveness in vibration suppression.
The first segment aluminum pipe is identical with the structure of second segment aluminum pipe, and diameter compares conventional air-conditioning by 9mm overstriking to 16mm
Aluminum pipe overstriking about 78%.Pipeline overstriking is in order to reduce the fluid pulsation of pipeline.
The common work covered by setting rubber hose, pipeline diameter overstriking, interpolation pipe expansion muffler, damping mass
With effectively reducing air-conditioning system fluid pulsation and pipeline vibration amplitude, make an uproar caused by air-conditioning system gas to reduce
Sound.
Noise caused by air-conditioning system gas is mainly shown as the high frequency order howling in vehicle accelerator, should
The main frequency uttered long and high-pitched sounds is easier to identify between 800-1000Hz.
Fig. 6 compared the present invention, and master drives the air-conditioning system order noise that position auris dextra (FLR) is tested in the car with former pipeline
As a result.Measurement condition is 40 DEG C of environment temperature under " blowing complete cold-interior circulation in face-", one grade of air blower of air-conditioning HVAC mode,
Engine speed is raised to 3000rpm or more from the even acceleration of idling., a in Fig. 6 is that the order of former air-conditioning duct tests frequency spectrum, and b is
Frequency spectrum is tested using the order of pipeline structure proposed by the present invention.Abscissa is the revolving speed of engine, and ordinate is noise point
Shellfish value.By the spectral contrast result of a and b it is found that entire speed stage air-conditioning system order noise reduction is obvious.It is directed to simultaneously
Former pipeline, using pipeline of the invention, air-conditioning system order noise testing process synchronizes subjective assessment twice, and score is by 6.5
Divide and is promoted to 7.5 points.From the point of view of integrating objective examination and subjective assessment, present invention noise caused by air-conditioning system gas drop
Aspect of making an uproar has good effect.
It may be noted that industry related technical personnel in technical scope mentioned according to the present invention, pass through structure, ginseng
The transformation and improvement that number adjustment carries out, should be covered by the protection scope of the present invention.
