Abstract
The invention discloses a silencer for a refrigerant line of an automotive air conditioning system. The silencer comprises a silencer body (4), an air inlet pipe (1) arranged on one side of the silencer body, and an air outlet pipe (5) arranged on the other side of the silencer body; a clapboard (2) is arranged in the silencer body (4); and an eccentric pipe (3) is arranged on the clapboard (2). The silencer for the refrigerant line of the automotive air conditioning system comprises the clapboard (2) with the eccentric pipe (3), so that after entering the refrigerant line, refrigerant gas can be reexpanded in a first cavity (6) and a second cavity (7) to convert part of sound energy into potential energy, meanwhile a turbulent flow is generated, and the sound energy spreading along the pipe can be partially retraced; thus, the flow noise of a refrigerant in the refrigerant line can be effectively reduced. The silencer has a simple structure, can be applied conveniently and has high efficiency of reducing noise.
Description
Technical field
The present invention relates to the car air conditioner field, particularly a kind of refrigerant line baffler of automotive air-conditioning system.
Background technique
Along with the development and the growth of automobile market, automotive engineering constantly develops and is ripe, and the user is also more and more higher for the requirement of car steering travelling comfort.Car noise is the primary problem that solves of car steering travelling comfort.For satisfying the demand that travelling comfort is driven, require auto parts and components when design, can take into full account noise level in the car running process, noise is more little, and the car steering travelling comfort is high more.The noise of automobile air conditioner compressor is that the primary problem that solves is produced in Automobile Design, and because the restriction of prior art, the noise that automobile air-conditioning refrigeration agent pipeline sends still can not effectivelyly solve.
Summary of the invention
The object of the present invention is to provide a kind of refrigerant line baffler of automotive air-conditioning system, solve the automotive air-conditioning system flow of refrigerant and the noise problem that produces.
For achieving the above object, the technical solution used in the present invention is:
The refrigerant line baffler of described this automotive air-conditioning system, comprise muffler body, be located at muffler body one side suction tude, be located at the steam outlet pipe of muffler body opposite side.
Described muffler body inside is cavity body structure, and described muffler body inside is provided with dividing plate.Described dividing plate is fixed on described muffler body cavity inner surface.
Described dividing plate is divided into two cavitys with described muffler body.Described two cavitys are divided into first cavity and second cavity.
On described dividing plate, be provided with eccentric pipeline.The axis of described eccentric pipeline and the axis of described air intake pipe are not point-blank.
The invention has the advantages that: owing to be provided with the dividing plate of eccentric pipeline in the refrigerant line baffler of described automotive air-conditioning system, can in first cavity and second cavity, obtain reexpansion after refrigerant gas enters and part acoustic energy is converted into potential energy, produce turbulent flow simultaneously and make and partly turn back along the acoustic energy of pipe transmmision.Can effectively reduce the hydrodynamic noise of refrigeration agent in refrigerant line like this.The utility model is simple in structure, and it is convenient to use, and reduces the efficient height of noise.
Description of drawings
Below the content of Figure of description expression of the present invention and the mark among the figure are made brief description:
Fig. 1 is the structural representation of the refrigerant line baffler of described automotive air-conditioning system;
Mark among the above-mentioned figure is:
1, suction tude, 2, dividing plate, 3, eccentric pipeline, 4, muffler body, 5, steam outlet pipe, 6, first cavity, 7, second cavity.
Embodiment
Contrast accompanying drawing below, by description to embodiment, embodiment such as mutual alignment between the related each several part and annexation etc. to invention, be described in further detail, design of the present invention, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The refrigerant line baffler of described this automotive air-conditioning system, comprise muffler body 4, be located at muffler body one side suction tude 1, be located at the steam outlet pipe 5 of muffler body opposite side.
Described muffler body 4 inside are cavity body structure, and described muffler body 4 inside are provided with dividing plate 2.Described dividing plate 2 is fixed on described muffler body 4 cavity inner surfaces.
Described dividing plate 2 is divided into two cavitys with described muffler body 4.Described two cavitys are divided into first cavity 6 and second cavity 7.
On described dividing plate 2, be provided with eccentric pipeline 3.The axis of the axis of described eccentric pipeline 3 and described air intake pipe 1 is not point-blank.
Principle of the present invention is: refrigeration agent enters in muffler body 4 first cavitys 6 by suction tude 1, because the barrier effect of dividing plate 2, the refrigeration agent back of expanding in first cavity 6 enters second cavity 7 by the eccentric pipeline 3 on the dividing plate 2 and reexpands acoustic energy partly is converted into potential energy, produce turbulent flow simultaneously and make and partly turn back along the acoustic energy of pipe transmmision, refrigeration agent flows out by steam outlet pipe 5, thereby noise is transformed, reach the purpose that reduces noise.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
