Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pump equipment, in particular to a noise reduction and vibration reduction exhaust pipe structure for an air source heat pump compressor. Background Art

[0002] Please refer to the instructions for Figure 1 and attached Figure 2 , Figure 1 This is a schematic diagram of the connection between the compressor and related components of the air source heat pump in the prior art. Figure 2 This is a connection diagram of a first elbow (200) in the prior art. As shown in the figure, a four-way valve (100) is connected to a compressor (101) via a first pipeline (200), the four-way valve (100) is further connected to a gas-liquid separator (102) via a second pipeline (300), and the four-way valve (100) is further connected to a titanium tube heat exchanger (103) via a third pipeline (400). The first pipeline (200) connected between the four-way valve (100) and the compressor (101) has the following defects in actual production or use conditions:

[0003] 1. The first pipeline (200) is designed with fewer bends and an inappropriate turning angle. Since the refrigerant flowing out of the compressor has a high flow rate after the compressor is started, the refrigerant cannot be effectively buffered in the first pipeline (200) with fewer bends, resulting in loud noise and vibration in the first pipeline (200), and the possibility of cracking and leaking refrigerant, which seriously affects the noise reduction and vibration reduction effect of the entire pipeline system and even affects the refrigeration effect.

[0004] 2. The first pipeline (200) needs to be connected to a high-pressure switch (201) and a needle valve (202). However, the diameter of the first pipeline (200) is small, only 7.94 mm. Welding the high-pressure switch (201) and the needle valve (202) on the first pipeline (200) is difficult, time-consuming, and inefficient. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a noise-reducing and vibration-absorbing exhaust pipe structure for an air source heat pump compressor to overcome the deficiencies in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] Furthermore, the first exhaust straight pipe is located on the upper left side of the compressor and is arranged to be tilted horizontally downward, and is deflected toward the lower left of the compressor with the compressor docking straight pipe as the center in the top view.

[0011] Furthermore, the fourth exhaust straight pipe is vertically arranged on the right front side of the compressor; a muffler is provided on the bypass of the fourth exhaust straight pipe.

[0012] Furthermore, two ends of the third buffer bend pipe are respectively connected to the third exhaust straight pipe and the fourth exhaust straight pipe, and the third buffer bend pipe is substantially bent toward the front of the compressor.

[0013] Furthermore, the fourth buffer bend is located on the right side of the compressor, and both ends of the fourth buffer bend are respectively connected to the fourth exhaust straight pipe and the four-way valve docking straight pipe; and the fourth buffer bend is bent along the front and rear direction of the compressor.

[0014] Furthermore, the four-way valve docking straight pipe is located at the right rear of the compressor, and the four-way valve docking straight pipe is vertically arranged and docked with the four-way valve.

[0015] Preferably, the outer diameter of the second exhaust straight pipe and the third exhaust straight pipe are both 7.94 mm, the thickness is 0.75 mm, and the welding insertion depth with the two ends of the expanded pipe is 12 mm; the inner diameter of the expanded pipe is greater than 7.94 mm.

[0016] Preferably, the diameters of the connecting pipes of the high-pressure switch and the needle valve are both 6.35 mm.

[0017] Preferably, the high-pressure switch and the needle valve are arranged on the expanded tube at intervals up and down.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1) In this case, a noise-reducing and vibration-damping exhaust pipe structure for an air-source heat pump compressor is provided with four sections of buffer elbows on the refrigerant pipeline. The four sections of buffer elbows bent in different directions are used to buffer the high-speed flow of refrigerant, thereby achieving the effect of noise reduction and vibration reduction.

[0020] 2) In this case, a noise-reducing and vibration-damping exhaust pipe structure for an air source heat pump compressor is provided, in which an expanded pipe is connected between the second exhaust straight pipe and the third exhaust straight pipe; the diameter of the expanded pipe is larger than the inner diameters of the second exhaust straight pipe and the third exhaust straight pipe, thereby solving the problem of drilling holes in a small pipe diameter for welding the connecting pipes of the high-voltage switch and the needle valve, and effectively improving production and assembly efficiency.

[0021] 3) In this case, a noise reduction and vibration reduction exhaust pipe structure for an air source heat pump compressor is provided with a muffler on the refrigerant pipeline to further improve the noise reduction and vibration reduction effect.

[0034] See also Figure 1-6 The utility model provides a noise reduction and vibration reduction exhaust pipe structure for an air source heat pump compressor, that is, the first pipeline 200 in the background technology, including a compressor docking straight pipe 1, a first buffer bend 2, a first exhaust straight pipe 3, a second buffer bend 4, a second exhaust straight pipe 5, an expansion pipe 6, a third exhaust straight pipe 7, a third buffer bend 8, a fourth exhaust straight pipe 9, a fourth buffer bend 10 and a four-way valve docking straight pipe 11 connected in sequence.

[0035] The compressor docking straight pipe 1 is located at the left rear of the compressor 101, and the compressor docking straight pipe 1 is vertically arranged and docked with the compressor 101 of the air heat pump;

[0036] The first exhaust straight pipe 3 is located above and to the left of the compressor 101 and is tilted downward horizontally. In a top view, it deflects toward the lower left of the compressor 101 with the compressor 101 docking straight pipe 1 as the center.

[0037] The first buffer elbow 2 has two ends connected to the compressor 101 docking straight pipe 1 and the first exhaust straight pipe 3 respectively;

[0038] The expanded tube 6 has its two ends connected to the second exhaust straight tube 5 and the third exhaust straight tube 7 respectively; the expanded tube 6, the second exhaust straight tube 5 and the third exhaust straight tube 7 are vertically and concentrically arranged on the left front side of the compressor 101; a high-pressure switch 201 and a needle valve 202 are bypassed on the expanded tube 6, and the high-pressure switch 201 and the needle valve 202 are spaced apart from each other.

[0039] Furthermore, the outer diameter of the second exhaust straight pipe 5 and the third exhaust straight pipe 7 are both 7.94 mm, the thickness is 0.75 mm, and the welding insertion depth at both ends of the expansion pipe 6 is 12 mm; the pipe diameters of the high-pressure switch 201 and the needle valve 202 are both 6.35 mm. Since the pipe diameters of 7.94 mm of the second exhaust straight pipe 5 and the third exhaust straight pipe 7 are relatively small, it is difficult to open holes to insert the high-pressure switch and the needle valve, so the pipeline needs to be expanded by the expansion pipe 6, thereby solving the problem of opening holes on small pipe diameters and effectively improving production efficiency.

[0040] The second buffer elbow 4 has two ends connected to the first exhaust straight pipe 3 and the second exhaust straight pipe 5 respectively;

[0041] The fourth exhaust straight pipe 9 is vertically arranged on the right front side of the compressor 101; a muffler 12 is provided on the fourth exhaust straight pipe 9 to further reduce the noise of the pipe;

[0043] The fourth buffer bend 10 is located on the right side of the compressor 101. The two ends of the fourth buffer bend 10 are respectively connected to the fourth exhaust straight pipe 9 and the four-way valve docking straight pipe 11; and the fourth buffer bend 10 is bent along the front-to-back direction of the compressor 101.

[0044] The four-way valve is connected to the straight pipe 11, which is located at the right rear of the compressor 101. The four-way valve is connected to the straight pipe 11, which is vertically arranged and connected to the four-way valve.

[0045] Compared with the existing technology, the anti-condensation water middle partition structure of an air source heat pump in this case is equipped with four sections of buffer bends and a silencer on the refrigerant pipeline. The four sections of buffer bends bent in different directions are used to buffer the high-speed flowing refrigerant, thereby achieving the effect of noise reduction and vibration reduction.

[0046] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
