Abstract
The utility model discloses a kind of air conditioner muffler, including muffler shell, the shell is ipsilateral to be disposed with inlet and outlet mouth, and housing cavity is provided with the current path of connection inlet and outlet mouth.Refrigerant since the internal diameter of housing cavity is larger, can expand when refrigerant passes through after air inlet enters muffler shell intracoelomic cavity, alleviate the pressure fluctuation of refrigerant in above scheme；Refrigerant enters after muffler again by ipsilateral discharge, so that refrigerant is elongated in the flowing stroke of muffler shell intracoelomic cavity, effectively pressure fluctuation is decayed, to reduce refrigerant generated hydrodynamic noise in air-conditioning duct, improves comfort when whole-vehicle air-conditioner system uses.
Description
Technical field
The utility model belongs to automobile air conditioning technology field, and in particular to a kind of muffler of pipelines of automobile air conditioner.
Background technique
With automobile industry going from strength to strength in China, automotive engineering reaches its maturity, and automotive air-conditioning system also starts to play
Important function.At work, refrigerant flows air-conditioning system in air-conditioning duct, can pass through compressor, condenser and steaming
Send out device.Since air-conditioning duct bending present in automobile front chamber is more, lead to the refrigerant pressure of everywhere in pipeline not
It is identical, so that pressure fluctuation can be generated in air-conditioning duct；Simultaneously as expansion valve (TXV) and compressor internally piloted valve in system
The adjusting that (becoming discharge capacity) carries out refrigerant flow in pipeline, so that the pressure fluctuation of refrigerant not can avoid.
Due to the presence of pressure fluctuation, air-conditioning system inevitably generates noise when working, this will seriously affect sky
Comfort when adjusting system uses.
Utility model content
The purpose of the utility model is to provide a kind of air conditioner mufflers, reduce in automotive air-conditioning system by refrigerant pressure arteries and veins
The raw noise of movable property.
To achieve the above object, the technical solution of the utility model is: a kind of air conditioner muffler, including muffler shell,
It is characterized by: the shell is ipsilateral to be disposed with inlet and outlet mouth, housing cavity is provided with the current path of connection inlet and outlet mouth.
The beneficial effect of above scheme is: refrigerant is after air inlet enters muffler shell intracoelomic cavity, due in shell
The internal diameter of chamber is larger, can expand when refrigerant passes through, and alleviates the pressure fluctuation of refrigerant；Refrigerant enter after muffler again by
Ipsilateral discharge effectively decays pressure fluctuation so that refrigerant is elongated in the flowing stroke of muffler shell intracoelomic cavity, to drop
Low refrigerant generated hydrodynamic noise in air-conditioning duct improves comfort when whole-vehicle air-conditioner system uses.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the utility model.
Specific embodiment
In conjunction with attached drawing, a kind of air conditioner muffler, including muffler shell 10, the shell 10 is ipsilateral to be disposed with air inlet
11, exhaust outlet 12,10 inner cavity of shell are provided with the current path of connection air inlet 11, exhaust outlet 12.In arrangement, can adopt
With inverted arrangement, muffler is mounted on evaporator to compressor circuit at the position of compressor air suction mouth.
When the refrigerant in air-conditioning system enters 10 inner cavity of muffler shell by air inlet by air-conditioning duct assembly, due to shell 10
The internal diameter of inner cavity is greater than the internal diameter of air-conditioning duct assembly, and refrigerant can expand, so that the pressure fluctuation of refrigerant be made to obtain
To alleviation；Refrigerant enters again by ipsilateral discharge after muffler, so that refrigerant becomes in the flowing stroke of muffler shell intracoelomic cavity
It is long, effectively pressure fluctuation is decayed, to reduce refrigerant generated hydrodynamic noise in air-conditioning duct, it is empty to improve vehicle
Comfort when adjusting system uses.
Further, the shell 10 is cylindrical shape, and inner cavity is provided with partition, and 10 inner cavity of shell is divided into three by partition
Chamber simultaneously constitutes winding type current path.When it is implemented, shell 10 is columnar hollow sealing cavity, in cavity with every
Plate is divided into the chambers of three connections, pressure arteries and veins when guiding refrigerant flowing in the cavity and alleviate refrigerant flowing
It is dynamic.
Preferably, the partition includes partition 1, partition 2 22, the length of the plate face of partition 1 perpendicular to shell 10
10 inner cavity of shell is divided into front chamber 30, rear chamber 40 by direction arrangement and partition 1, and partition 2 22 is arranged in front chamber 30, every
The plate face of plate 2 22 is overlapped with the radial centre lines of shell 10, and front chamber 30 is divided into inlet chamber 31 and discharge chamber by partition 2 22
32, inlet chamber 31, discharge chamber 32 are connected to air inlet 11, exhaust outlet 12 respectively；The partition 1 is located at 2 22 two sides of partition
It is respectively arranged with pipe 1, pipe 2 212, inlet chamber 31, discharge chamber 32 are connected to by Guan Yi 211, pipe 2 212 with rear chamber 40.
By partition 1, partition 2 22 and pipe 1, pipe 2 212 by 10 inner cavity of shell be divided into three chambers and be connected to constitute it is circuitous
Return formula current path, after this programme is used for air-conditioning duct, refrigerant from air inlet 11 enter shell 10, along inlet chamber 31, after
Chamber 40, discharge chamber 32 are flowed and are flowed out by exhaust outlet 12, U-shaped current path are constituted in shell 10, stroke is longer, effectively
Alleviate refrigerant flowing when pressure fluctuation.
