Embodiment Construction

[0015] The specific embodiments of the present invention will be described in further detail below through the description of the embodiments with reference to the accompanying drawings.

[0016] A pipeline muffler for an automobile air-conditioning system, such as figure 1 As shown, the muffler is installed in the refrigerant circulation pipeline, including the housing 3 and the inlet pipe 1 and the outlet pipe 2 arranged on the same wall of the housing 3. The inlet pipe 1 is located above the outlet pipe 2 to facilitate the outflow of gas. , and the air inlet pipe 1 and the air outlet pipe 2 are arranged axisymmetrically with the central axis of the housing 3, which is convenient for processing. A reflection plate 4 is provided on the side opposite to the inlet pipe 1 and the outlet pipe 2 in the housing 3. After entering the cavity, the refrigerant gas flows backwards and collides with the reflection plate 4, changes the path and flows out from the outlet pipe 2, and consum...

Abstract

The invention discloses a silencer of an automobile air-conditioning system pipeline. The silencer is installed in a refrigerant circulation pipeline, and comprises a shell (3), a gas intake pipe (1) and a gas exhaust pipe (2), wherein the gas intake pipe (1) and the gas exhaust pipe (2) are arranged on the same wall surface of the shell; the shell (3) is internally provided with a reflection plate (4) at the opposite side of the gas intake pipe (1) and the gas exhaust pipe (2). The silencer of the automobile air-conditioning system pipeline is simple in structure, is convenient to connect, and can well reduce noise generated by the flowing of an automobile air-conditioning system refrigerant in a pipeline, so that the influences on noise inside and outside an automobile by gas intake noise can be reduced, and the NVH performances of a finished automobile are improved.

Description

technical field [0001] The invention belongs to the field of automobile air-conditioning, and more specifically relates to a pipeline muffler for reducing the flow noise of refrigerant in an automobile air-conditioning system. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the driving comfort of the vehicle, and the interior noise is one of the important indicators of the driving comfort. When drivers and passengers use the air conditioner, the air conditioning system will generate a certain amount of noise, which often has a greater impact on the NVH of the entire vehicle, and the flow of the refrigerant in the automotive air conditioning system generates greater noise. Therefore, further noise reduction improvements are needed in this regard. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problems existing in the prior art, provide a simple structure, ea...
