Abstract

The utility model discloses a novel muffler which comprises two barrels formed integrally. The two sides of each barrel are respectively provided with a transition section; the transition section outside the barrel is connected with a pipeline interface section; the transition section inside the barrel is connected with a barrel connecting section. The two barrels are connected together through the barrel connecting section. The pipe diameter of the barrel connecting section is smaller than the diameter of the barrel to form two muffler structures so as to play the role of dual noise reduction effects and reduce the noises of an air conditioner; in addition, as the novel muffler is an integrally formed structure, welding is not needed; therefore, the problem of refrigerating fluid leakage caused due to welding quality is overcome. The novel muffler has the technical effect of stable connection.

Description

A kind of novel muffler

Technical field:

The utility model relates to the air conditioner refrigerating technical field, especially relates to the muffler in the air-conditioning refrigeration system.

Background technology:

See shown in Figure 1: be used for the muffler of air-conditioning refrigeration system at present, adopt single cylindrical shell to carry out noise reduction usually and handle, erasure effect is obvious inadequately, and the length resistance to pressure is poor because of length.Also there is employing that two muffler Combination Welding are become the design of a muffler, but, during welding, problems such as welding pore, rosin joint usually occurs, cause system refrigerant to leak outside, have a strong impact on unit performance owing to it is that the welding manner connection is processed

The utility model content:

The purpose of the utility model provides a kind of novel muffler with regard to being the weak point that exists to prior art, it have good muffling effect, resistance to pressure strong, can eliminate the characteristics that cold-producing medium leaks outside.

For realizing above-mentioned purpose; The novel muffler of the utility model includes the integrated cylindrical shell of two joints; The both sides of every joint cylindrical shell have changeover portion respectively; The changeover portion in the cylindrical shell outside links to each other with the pipe interface section, and the inboard changeover portion of cylindrical shell links to each other with the cylindrical shell linkage section, and two joint cylindrical shells link together via the cylindrical shell linkage section.

Preferred as technique scheme, the inboard changeover portion of described cylindrical shell is spent less than 90 with the horizontal sextant angle of cylindrical shell.

Preferred as technique scheme, described barrel is provided with filter and/or silencing means.

The beneficial effect of the utility model is: the caliber of its cylindrical shell linkage section forms two muffler structures less than barrel diameter, plays dual erasure effect, reduces the air-conditioning noise; In addition,, need not to weld, overcome problem, have the stable technique effect of connection because the cold-producing medium that welding quality causes leaks outside because of its structure that is formed in one.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is the structural representation of existing muffler;

Fig. 2 is the external structure sketch map of one of the utility model embodiment;

Fig. 3 is two the external structure sketch map of the utility model embodiment;

Fig. 4 is three the external structure sketch map of the utility model embodiment;

Fig. 5 is four the sectional structure sketch map of the utility model embodiment.

The specific embodiment:

See shown in Figure 2: the novel muffler of the utility model includes the integrated cylindrical shell 10 of two joints; The both sides of every joint cylindrical shell 10 have changeover portion 11 respectively; The changeover portion 11 in cylindrical shell 10 outsides links to each other with pipe interface section 12; Cylindrical shell 10 inboard changeover portions 11 link to each other with cylindrical shell linkage section 13, and two joint cylindrical shells 10 link together via cylindrical shell linkage section 13, and cylindrical shell 10 inboard changeover portions 11 are spent less than 90 with the horizontal sextant angle of cylindrical shell 10.

See shown in Figure 3: the diameter of cylindrical shell linkage section 13 and pipe interface section 12 do not wait; See shown in Figure 4: two joint cylindrical shells 10 can be dissymmetrical structure.

In addition, cylindrical shell 10 inside also can be provided with filter 20 and/or silencing means 30, and are as shown in Figure 5: first segment cylindrical shell 10 set inside be provided with silencing means 30 in filter 20, the second joint cylindrical shells 10.

The above is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
