Abstract

The utility model relates to an automotive air conditioner silencer which comprises an inlet connection pipe, an outlet connection pipe and an expansion chamber pipe. The inlet connection pipe, the outlet connection pipe and the expansion chamber pipe are arranged in an air conditioner refrigerating system. The expansion chamber pipe is of an arch structure, the two ends of the arch structure are connected to the outer wall surface of the inlet connection pipe and the outer wall surface of the outlet connection pipe, a silencing interlayer is arranged at the ends, which are close to each other, of the inlet connection pipe and the outlet connection pipe, and the silencing interlayer is filled with silencing sponge. The automotive air conditioner silencer has the advantages that the structure is simple, manufacturing is easy, the silencer formed by a silencing chamber and the silencing interlayer has large silencing frequency range, the silencer is particularly suitable for office environment needing quiet atmosphere, the silencing effect is better than that of a common product, and the silencer wins unanimous praise of the majority of users.

Description

Air conditioning for automobiles silencer

Technical field

The utility model relates to air conditioner refrigerating technical field, particularly a kind of air conditioning for automobiles silencer.

Background technology

Current existing air-conditioner all exists operation noise problem, muffler is generally all set on the suction pipeline of air-conditioner refrigerating system, what this muffler generally adopted is the muffler of physical arrangement formula, its noise reduction frequency range is narrow, and the indelible phenomenon of the noise that exists certain frequency, and for the working environment of a quiet atmosphere of needs, existing air conditioning for automobiles silencer all can not reach requirement, have a strong impact on office progress and office efficiency, also do not had product or the method that can address these problems to occur at present.

Utility model content

The purpose of this utility model is to provide a kind of air conditioning for automobiles silencer, simple in structure, is easy to manufacture, and has the erasure effect more outstanding than common product, to overcome currently available technology above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of air conditioning for automobiles silencer, comprise the entrance sleeve, discharge connection and the expansion chambers pipe that in air-conditioner refrigerating system, arrange, described expansion chambers pipe is bow-shaped structural, and described arched both ends are connected in the outer wall surface of described entrance sleeve, described discharge connection, the end that described entrance sleeve and described discharge connection are close is provided with noise reduction interlayer, in described noise reduction interlayer, is filled with noise reduction sponge.

Above-mentioned air conditioning for automobiles silencer, also comprises the second expansion chambers pipe, and described the second expansion chambers pipe and described expansion chambers pipe, about the axis symmetry of described entrance sleeve, form noise reduction chamber between described the second expansion chambers pipe and described expansion chambers pipe.

Above-mentioned air conditioning for automobiles silencer, described entrance sleeve and described discharge connection are all to the outdoor extension of described silencing cavity and form inlet tube extension, outlet extension, and described inlet tube extension is connected with the refrigerating plant in air-conditioner refrigerating system respectively with described outlet extension.

The beneficial effects of the utility model are: simple in structure, be easy to manufacture, the muffler being jointly made up of noise reduction chamber and noise reduction interlayer has higher noise reduction frequency range, its erasure effect is than the good muffling effect of common product, be particularly useful for the office environment of atmosphere that needs peace and quiet, and obtained users' consistent favorable comment.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the cross-sectional view of air conditioning for automobiles silencer described in the utility model embodiment.

In figure:

1, entrance sleeve; 2, discharge connection; 3, expansion chambers pipe; 4, noise reduction interlayer; 5, noise reduction sponge; 6, the second expansion chambers pipe; 7, noise reduction chamber; 8, inlet tube extension; 9, outlet extension.

The specific embodiment

As shown in Figure 1, a kind of air conditioning for automobiles silencer described in the utility model embodiment, comprise the entrance sleeve 1 arranging in air-conditioner refrigerating system, first chamber pipe 3 of discharge connection 2 and expansion, first chamber pipe 3 of described expansion is bow-shaped structural, and described arched both ends are connected in described entrance sleeve 1, the outer wall surface of described discharge connection 2, adopt bow-shaped structural can make to be connected between described chamber pipe 3 and the outer wall of described entrance sleeve 1 or described discharge connection 2 more convenient, connect effect closely if adopt rectangular configuration not reach, and in use likely occur that first chamber of described expansion manage 3 obscissions, described entrance sleeve 1 is provided with noise reduction interlayer 4 with the end that described discharge connection 2 is close, in described noise reduction interlayer, be filled with noise reduction sponge 5, described noise reduction interlayer 4 can slow down flowing of the interior cooling-air of refrigeration system with described noise reduction sponge 5, and then reduction noise.

A kind of air conditioning for automobiles silencer described in the utility model embodiment, also comprise the second expansion chambers pipe 6, first chamber pipe 3 axis symmetry about described entrance sleeve 1 of described the second expansion chambers pipe 6 and described expansion, between first chamber pipe 3 of described the second expansion chambers pipe 6 and described expansion, form noise reduction chamber 7, described noise reduction chamber 7 is an enclosed construction, the mobile meeting of cooling-air is carried out in described noise reduction chamber 7, and described noise reduction chamber 7 and described noise reduction interlayer 4, described noise reduction sponge 5 actings in conjunction are in reducing noise.

Further, described entrance sleeve 1 with described discharge connection 1 all to described noise reduction chamber 7 extensions and form inlet tube extension 8, outlet extension 9, described inlet tube extension 8 is connected with the refrigerating plant in air-conditioner refrigerating system respectively with described outlet extension 9, can prevent that external refrigeration device is directly connected with described entrance sleeve 1, discharge connection 2 time, there is slip phenomenon between first chamber pipe 3 of described expansion, described the second expansion chambers pipe 6, also can prevent that becoming flexible from appearring in described noise reduction interlayer 4 and the fixed position of described noise reduction sponge 5 simultaneously.

The utility model air conditioning for automobiles silencer simple in structure, between each parts, assembling easily, and each parts are all easy to manufacture, the noise-reducing structure being jointly made up of noise reduction chamber and noise reduction interlayer is enclosed construction, and noise is difficult for spreading out of, and has higher noise reduction frequency range, its erasure effect is than the good muffling effect of common product, be particularly useful for the needing peace and quiet working environment of atmosphere, for manufacturer has brought certain economic benefit, and has obtained users' consistent favorable comment.

Above-described embodiment is only for the utility model creation example is clearly described, and not the utility model is created the restriction of the specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.All any apparent variations of being extended out within spirit of the present utility model and principle or variation are still among the utility model is created the protection domain of claim.
