Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a spiral air conditioner silencer. Background Art

[0002] When the air source heat pump is running, as the frequency of the compressor continues to increase, the vibration and noise of the unit also increase. At night, the loud noise will affect the user's sleep, thus giving the user a bad experience. The vibration of the compressor will also cause resonance of the sheet metal and pipes. The sheet metal resonance will produce intermittent humming sounds, affecting the user's life. The pipe resonance will cause the pipe to shake violently. Long-term shaking will cause metal fatigue and eventually cracking. The refrigerant will leak and the unit will not be able to be used normally. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a spiral air conditioner silencer, which has a simple structure, prolongs the service life and reduces noise pollution.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A spiral air conditioner silencer comprises a shell and a connecting pipe, wherein the connecting pipe is fixed on the shell, the bottom end of the connecting pipe extends into the shell, and the bottom end is connected to a spiral pipe, the spiral pipe is provided with radial jet holes along the outer edge of the spiral, and a jet ring is installed at the bottom end of the spiral pipe, and axial jet holes are distributed on the jet ring.

[0006] A further technical solution is that the top end side of the shell is also provided with a flange extending upward, and the connecting pipe is installed on the flange at the top end of the shell. The connecting pipe can be installed and fixed on the inner side of the flange at the top end of the shell by welding or threading.

[0007] The beneficial effects of the utility model are:

[0008] 1. Since the refrigerant is ejected along the radial direction of the spiral tube, the disturbance in a single direction is offset, so the vibration amplitude of the shell in the radial direction will be greatly reduced, thereby improving the vibration of the pipeline. When the pipeline amplitude is reduced, metal fatigue will also be reduced accordingly, thereby increasing the service life of the unit;

[0009] 2. When the high-temperature and high-pressure refrigerant in the spiral tube flows out from the jet hole, the pressure drops rapidly and the flow rate decreases. After expanding inside the shell, the noise is greatly reduced. At the same time, the operating load of the compressor will also be reduced, and the vibration and noise during operation will also be improved. At the same time, the resonance points with the pipeline and sheet metal will also be reduced accordingly, and the performance of the unit will be optimized;

[0010] 3. When the high-temperature and high-pressure refrigerant in the spiral tube flows out from the jet hole, the pressure drops rapidly and the flow rate decreases. After expanding inside the shell, the noise is greatly reduced. At the same time, the operating load of the compressor will also be reduced, and the vibration and noise during operation will also be improved. At the same time, the resonance points with the pipeline and sheet metal will also be reduced accordingly, and the performance of the unit will be optimized. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] See also Figures 1 to 4 As shown, a spiral air-conditioning silencer includes a shell 2 and a connecting pipe 1. The connecting pipe 1 is fixed on the shell 2. The bottom end of the connecting pipe 1 extends into the shell 2 and is connected to a spiral pipe 3 on the bottom end. The spiral pipe 3 has radial jet holes 4 distributed along the outer edge of the spiral. A jet ring 6 is installed at the bottom end of the spiral pipe 3, and axial jet holes 5 are distributed on the jet ring 6.

[0019] The top side of the shell 2 is also provided with an upwardly extending flange 7, and the pipe 1 is installed on the flange 7 at the top of the shell 2. The pipe 1 can be installed and fixed on the inner side of the flange 7 at the top of the shell 2 by welding or threading.

[0020] In this embodiment, Figure 1 The arrow shown in the figure is a label on the outside of the shell 2. The direction indicated by the arrow is the flow direction of the refrigerant, that is, it enters from the connecting pipe 1 and is discharged from the bottom end of the shell 2. Working principle: the high-temperature and high-pressure refrigerant discharged from the compressor flows to the spiral tube 3 through the connecting pipe 1; at this time, part of the refrigerant in the spiral tube 3 flows out from the radial jet holes 4 of the spiral tube 3, and part flows out from the axial jet holes 5. Since the refrigerant is ejected along the radial direction of the spiral tube 3, the disturbance in a single direction is offset, so the amplitude of the shell 2 in the radial direction will be greatly reduced, thereby improving the vibration of the pipeline; after the amplitude of the pipeline is reduced, the metal fatigue will also be reduced accordingly, thereby increasing the service life of the unit.

[0021] When the refrigerant is sprayed onto the inner wall of the shell 2, it will flow downward along the inner wall spiral and flow out from the lower end of the shell 2; the refrigerant airflow flowing spirally downward in the shell 2 will flow more smoothly in a laminar manner, reducing the disturbance to the shell 2, and the noise of the gas flow will be reduced accordingly, and the user experience will be improved accordingly. When the high-temperature and high-pressure refrigerant in the spiral tube 3 flows out from the jet hole, the pressure drops rapidly, the flow rate decreases, and after expanding inside the shell 2, the noise is greatly reduced; at the same time, the operating load of the compressor will also be reduced, and the vibration and noise during operation will also be improved; at the same time, the resonance points with the pipeline and sheet metal will also be reduced accordingly, and the performance of the unit will be optimized.

The pipe 1 is composed of a copper tube with an outer diameter of 9.52mm to 15.88mm and a wall thickness of 1.0mm-1.2mm, and the inner diameter of the end is expanded to the corresponding outer diameter of the copper tube; 2. The spiral tube 3 is formed by spirally bending a copper tube with an outer diameter of 6.35mm to 15.88mm and a wall thickness of 0.8mm to 1.2mm, and a plurality of radial jet holes 4 with a diameter of 2 to 4mm are opened on the tube; 3. The shell 3 is made of a copper rigid body with an outer diameter of 28 to 50mm and a wall thickness of 1.5mm to 2.5mm; 4. The pipe 1 and the spiral tube 3 are connected by welding; 5. The pipe 1 is connected to the shell 2 by welding; 6. The jet ring 6 is connected to the spiral tube 3 by welding; 7. The label ( Figure 1 The shell 2 is glued together with the arrow shown by the refrigerant, and the direction of the arrow points to the direction of refrigerant flow.
