Abstract

The utility model discloses a corrugated folded plate muffler comprising a copper air inlet pipe, a copper air outlet pipe, a stainless steel shell and a stainless steel muffling pipe. The air inlet pipe and the air outlet pipe are welded to two ends of the shell, the muffling pipe is welded inside the shell, a vacuum chamber is encircled between the muffling pipe and the shell, one end of the shell is provided with an air exhaust nozzle, four layers of corrugated folded plates equal in spacing distance are welded on the inner wall of the muffling pipe, sound absorption plates are arranged on both sides of each of the two middle layers of corrugated folded plates, and sound absorption plates are also arranged on the inner sides of the other two layers of corrugated folded plates. Compared with the prior art, the corrugated folded plate muffler has the advantages that the shell and the muffling pipe are made of stainless steel, so that production cost is lowered, and the defect that the muffling pipe is easy to rust is overcome; due to the corrugated folded plates and the sound absorption plates, sound intensity is lowered greatly, sound in a refrigerant pipe is eliminated basically, and muffling effect is quite obvious.

Description

A kind of ripple flap muffler

Technical field

The utility model relates to air conditioner parts field, specifically a kind of for eliminating the ripple flap muffler of the coolant noise of air conditioner refrigerating pipe-line system.

Background technology

The muffler of air conditioner refrigerating pipe-line system is a kind of parts that not only can make air-flow pass through but also can effectively reduce noise.The hush pipe of traditional muffler, air inlet pipe and escape pipe all adopt copper pipe to make, because copper product price is high, make muffler cost higher, As time goes on, the serviceability of the hush pipe of copper product will decline, and the copper product contacting with air can get rusty.The result of use of a lot of mufflers is all relatively good in the market, but the sound transmission that still has some strength in the process of noise reduction out, produces noise, sound do not eliminated minimum.

Utility model content

The purpose of this utility model is to provide that a kind of production cost is low, the ripple flap muffler of good muffling effect, to solve the problem proposing in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of ripple flap muffler, comprise air inlet pipe, escape pipe, shell body and hush pipe, described air inlet pipe and escape pipe are copper pipe, described shell body and hush pipe material are stainless steel, described air inlet pipe and escape pipe are welded on the two ends of shell body, described shell body one end upside is provided with air exhaust nozzle, described hush pipe is welded on shell body inside, and surround vacuum chamber between hush pipe and shell body, on hush pipe inwall, be welded with four layers of fold-type corrugated plating, the two ends of middle two-layer fold-type corrugated plating are all welded on the inwall of hush pipe by reticular lamina, and the two sides of middle two-layer fold-type corrugated plating is equipped with abatvoix, the medial surface of two-layer fold-type corrugated plating is also equipped with abatvoix in addition.

As further program of the utility model: the spacing distance of described four layers of fold-type corrugated plating all equates.

As further program of the utility model: the material of described abatvoix is that wave is continuous, alumina silicate is continuous or polyester fiber.

As the utility model scheme further: described shell body equates with the thickness of hush pipe.

Compared with prior art, the beneficial effects of the utility model are: shell body and hush pipe use stainless steel material, have reduced production cost, have overcome the shortcoming of easily getting rusty of hush pipe; Employing fold-type corrugated plating frequently changes the direction of propagation of sound, has increased greatly the propagation distance of sound, and recycling abatvoix constantly absorbs sound, greatly reduces the intensity of sound, has substantially eliminated the sound in refrigerant pipe, and erasure effect is very obvious.

Accompanying drawing explanation

Fig. 1 is the structural representation of ripple flap muffler.

In figure: 1-air inlet pipe; 2-escape pipe; 3-shell body; 4-hush pipe; 5-fold-type corrugated plating; 6-vacuum chamber; 7-reticular lamina; 8-abatvoix; 9-air exhaust nozzle.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, in the utility model embodiment, a kind of ripple flap muffler, comprise air inlet pipe 1, escape pipe 2, shell body 3 and hush pipe 4, air inlet pipe 1 and escape pipe 2 are copper pipe, and shell body 3 and hush pipe 4 materials are stainless steel, and shell body 3 equates with the thickness of hush pipe 4; Air inlet pipe 1 and escape pipe 2 are welded on the two ends of shell body 3, conveniently weld or are connected with air-conditioner hose.

Hush pipe 4 is welded on shell body 3 inside, and surround vacuum chamber 6 between hush pipe 4 and shell body 3, shell body 3 one end are provided with air exhaust nozzle 9, be convenient to vacuum chamber 6 to be evacuated, in the process of noise reduction, the effect of vacuum chamber 6 is controlled at sound in hush pipe 4 completely, prevents that sound from spreading out of shell body 3, further reduce the effect of noise reduction, its noise reduction process is very steady.

On hush pipe 4 inwalls, be welded with all equal fold-type corrugated platings 5 of four layers of spacing distance, the two ends of middle two-layer fold-type corrugated plating 5 are all welded on the inwall of hush pipe 4 by reticular lamina 7, and the two sides of middle two-layer fold-type corrugated plating 5 is equipped with abatvoix 8, the medial surface of two-layer fold-type corrugated plating 5 is also equipped with abatvoix 8 in addition, and the material of abatvoix 8 is that wave is continuous, alumina silicate is continuous or polyester fiber.

In the process of noise reduction, utilize fold-type corrugated plating 5 to change frequently the direction of propagation of sound, increased greatly the propagation distance of sound, the extraordinary abatvoix 8 of recycling sound-absorbing effect constantly absorbs sound, greatly reduce the intensity of sound, sound is substantially all absorbed in hush pipe 4, and erasure effect is very obvious.

To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
