Embodiment 1

[0020] Referring to Fig. 1, what is shown in the figure is the muffler in the prior art, the difference of this embodiment is that its whole body (including cylinder 1 and necking 2, 2') is made of magnesium alloy material, but in Copper plating is applied to the straight sections at the two ends of the shrinkage 2 and 2'.

Embodiment 2

[0022] Referring to Fig. 4, the muffler is shown in the figure, and its difference from Fig. 1 is that the copper connection parts at both ends of the cylinder are copper sleeves 3, 3' welded on the outer surfaces of the shrinkages 2, 2'.

[0023] As an alternative to Embodiment 2, one or all of the copper sleeves 3, 3' in FIG. 4 are replaced by aluminum alloy sleeves.

Embodiment 3

[0025] Referring to Fig. 2, what is shown in the figure is the filter in the prior art, the difference of this embodiment is that the cylinder body 1 and the filter screen frame 4 in this embodiment are made of magnesium alloy material, and the filter screen The wire 5 is made of stainless steel, and a copper layer (not shown in the figure) is added to the straight section of the shrinkage part 2 at both ends of the cylinder body 1 by copper plating. In this embodiment, as an alternative, the screen frame 4 can be replaced by magnesium material.

Abstract

This invention provides three air conditioning pipe connection parts of silencer, filter and drying filter, each of which comprises cylinder and copper connection part onto both ends of cylinder, wherein, the cylinder is made of magnesia alloy materials as optimization; the said cylinder two ends comprise one contract window with smaller radium; the said copper connection part is added to contract mouth.

Description

technical field [0001] The invention relates to an air conditioner pipe connection piece. More specifically, the present invention relates to three kinds of pipeline connectors in the air conditioner, the muffler, the filter, and the dry filter. Background technique [0002] Silencers, filters, and filter drier are important auxiliary devices in air-conditioning equipment. What they have in common is that the three devices have the same shape and size, and are basically cylindrical (cylinder 1), and the shells are all rolled and formed by copper. , wherein, the muffler (see Figure 1) has two types of outlet end and inlet end with the same diameter and different diameters, which are installed in the refrigeration system to play the role of buffering and decompression, so as to achieve the effect of noise reduction; filter (see The inside of Fig. 2) is fixed with a filter screen mesh frame 4, and one side of the filter screen frame 4 is connected with the filter screen mesh w...
