[0031] As Figures 1 to 3 According to a first aspect of the present application, there is provided a flow- around exhaust passage structure, the flow-around exhaust passage structure including an exhaust passage main body 1.
[0032] In the following description, reference is made to the Figures 1 to 3 The specific structure of the above components of the flow-around exhaust passage structure and the connection relationship of the above components are specifically described.
[0033] As Figures 1 to 3As shown, in this embodiment, the exhaust channel body 1 can be installed on the inner wall of the casing 40 of the scroll compressor 4. The exhaust channel body 1 may include an inlet 110, a horizontal exhaust port 120, and a vertical exhaust port 130. The inlet 110 can be positioned directly opposite the outlet of the gas passage 410 of the scroll compressor 4, so that the refrigerant gas mixed with liquid refrigeration oil will directly enter the exhaust channel body 1 after flowing out of the gas passage 410. The horizontal exhaust port 120 and the vertical exhaust port 130 are connected to the inlet 110. A portion of the refrigerant gas in the exhaust channel body 1 will be discharged through the horizontal exhaust port 120, and another portion will be discharged through the vertical exhaust port 130. The horizontal exhaust port 120 can exhaust along the circumference of the casing 40, allowing the refrigerant gas discharged from the horizontal exhaust port 120 to flow around the casing 40. During the flow motion, due to the weight difference between the refrigerant gas and the liquid refrigeration oil, they will separate under the action of centrifugal force. The vertical exhaust port 130 can be located between the winding 420 of the scroll compressor 4 and the shell 40. The refrigerant gas discharged from the vertical exhaust port 130 will have sufficient contact with the winding 420. This process increases the separation efficiency of the refrigeration oil and can cool the winding 420 of the motor 42, thereby effectively reducing the oil circulation rate of the scroll compressor 4.
[0034] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the exhaust channel body 1 can be a tubular structure with one side open. The exhaust channel body 1 can be fastened to the inner wall of the pipe shell 40, so that a channel for gas flow is formed between the exhaust channel body 1 and the inner wall of the pipe shell 40. A flange 3 can also be formed on the outer periphery of the exhaust channel body 1, and the flange 3 can be integrally formed with the exhaust channel body 1. The flange 3 can fit against the inner wall of the pipe shell 40, and the exhaust channel body 1 can be welded and fixed to the inner wall of the pipe shell 40 through the flange 3, thereby realizing the connection and sealing between the exhaust channel body 1 and the pipe shell 40.
[0035] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the exhaust channel body 1 may include an intake pipe section 11, a first exhaust pipe section 12, and a second exhaust pipe section 13. The intake pipe section 11 may be arranged vertically, and the intake port 110 may be formed at the top end of the intake pipe section 11. Preferably, the intake pipe section 11 and the gas passage 410 may be arranged on the same axis, such that the exhaust port at the lower end of the gas passage 410 is directly opposite the intake port 110 at the top end of the intake pipe section 11. The first exhaust pipe section 12 may be arranged horizontally. The first end of the first exhaust pipe section 12 (which may be as follows) Figure 1The bottom end of the first gas inlet pipe 11 can be connected to the left end of the first gas outlet pipe 12, so that the refrigerant gas can flow to the first gas outlet pipe 12. The second end of the first gas outlet pipe 12 (which can be the right end as shown in the figure) can be formed as a horizontal exhaust port 120, so that the refrigerant gas can be discharged through the horizontal exhaust port 120. Since the first gas outlet pipe 12 is attached to the inner wall of the pipe shell 40, the refrigerant gas discharged from the horizontal exhaust port 120 will flow along the circumference of the pipe shell 40. The second gas outlet pipe 13 can be arranged in the vertical direction. The top end of the second gas outlet pipe 13 can be connected to the first gas outlet pipe 12, so that the refrigerant gas can flow to the second gas outlet pipe 13. The bottom end of the second gas outlet pipe 13 can be formed as a vertical exhaust port 130, and part of the refrigerant gas will be discharged from the vertical exhaust port 130 to contact the winding 420. Figure 1 The second end of the first gas outlet pipe 12 (which can be the right end as shown in the figure) can be formed as a horizontal exhaust port 120, so that the refrigerant gas can be discharged through the horizontal exhaust port 120. Since the first gas outlet pipe 12 is attached to the inner wall of the pipe shell 40, the refrigerant gas discharged from the horizontal exhaust port 120 will flow along the circumference of the pipe shell 40. The second gas outlet pipe 13 can be arranged in the vertical direction. The top end of the second gas outlet pipe 13 can be connected to the first gas outlet pipe 12, so that the refrigerant gas can flow to the second gas outlet pipe 13. The bottom end of the second gas outlet pipe 13 can be formed as a vertical exhaust port 130, and part of the refrigerant gas will be discharged from the vertical exhaust port 130 to contact the winding 420.
[0036] Preferably, as shown in the figure, in the embodiment, a circular arc transition portion 14 can also be formed at the bottom end of the first gas inlet pipe 11. The circular arc transition portion 14 can be a fan-shaped pipe segment, and the angle between the axis of the outlet end and the axis of the inlet end of the circular arc transition portion 14 can be 90°. The first end of the first gas outlet pipe 12 can be connected to the bottom end of the first gas inlet pipe 11 through the circular arc transition portion 14. Specifically, the bottom end of the first gas inlet pipe 11 can be connected to the inlet end of the circular arc transition portion 14, and the first end of the first gas outlet pipe 12 can be connected to the outlet end of the circular arc transition portion 14. The circular arc transition portion 14 can have a flow guiding effect, so that the refrigerant gas moving in the vertical direction can be guided in the horizontal direction. At the same time, the circular arc transition portion 14 can also increase the contact between the refrigerant gas and the exhaust passage main body, so as to promote oil separation. Figures 1 to 3 Further preferably, as shown in the figure, in the embodiment, the bottom end of the first gas inlet pipe 11 and the top end of the second gas outlet pipe 13 can be arranged with a spacing in the horizontal direction, i.e. the first gas inlet pipe 11 and the second gas outlet pipe 13 are arranged staggered in the horizontal direction, so as to avoid the refrigerant gas flowing directly out of the bottom end of the second gas outlet pipe 13. Further, preferably, the circular arc transition portion 14 can be arranged between the bottom end of the first gas inlet pipe 11 and the top end of the second gas outlet pipe 13. In this case, the refrigerant gas will first change to horizontal direction movement, and then flow through the top end of the second gas outlet pipe 13, so as to avoid the refrigerant gas flowing to the second gas outlet pipe 13.
[0037] Figures 1 to 3 Further preferably, as shown in the figure, in the embodiment, the bottom end of the first gas inlet pipe 11 and the top end of the second gas outlet pipe 13 can be arranged with a spacing in the horizontal direction, i.e. the first gas inlet pipe 11 and the second gas outlet pipe 13 are arranged staggered in the horizontal direction, so as to avoid the refrigerant gas flowing directly out of the bottom end of the second gas outlet pipe 13. Further, preferably, the circular arc transition portion 14 can be arranged between the bottom end of the first gas inlet pipe 11 and the top end of the second gas outlet pipe 13. In this case, the refrigerant gas will first change to horizontal direction movement, and then flow through the top end of the second gas outlet pipe 13, so as to avoid the refrigerant gas flowing to the second gas outlet pipe 13.
[0038] Further preferably, as shown in the figure, in the embodiment, the bottom end of the first gas inlet pipe 11 and the top end of the second gas outlet pipe 13 can be arranged with a spacing in the horizontal direction, i.e. the first gas inlet pipe 11 and the second gas outlet pipe 13 are arranged staggered in the horizontal direction, so as to avoid the refrigerant gas flowing directly out of the bottom end of the second gas outlet pipe 13. Further, preferably, the circular arc transition portion 14 can be arranged between the bottom end of the first gas inlet pipe 11 and the top end of the second gas outlet pipe 13. In this case, the refrigerant gas will first change to horizontal direction movement, and then flow through the top end of the second gas outlet pipe 13, so as to avoid the refrigerant gas flowing to the second gas outlet pipe 13. Figures 1 to 3 As shown, in this embodiment, the bypass-type exhaust passage structure may further include a guide protrusion 2, which may be integrally formed with the exhaust passage body 1. The guide protrusion 2 protrudes from the inner wall of the exhaust passage body 1 to change the flow direction of the refrigerant gas within the exhaust passage body 1. The guide protrusion 2 may be located at the connection between the intake pipe section 11 and the first exhaust pipe section 12 (i.e., above the arc transition section 14). The guide protrusion 2 can further guide the vertical airflow to the horizontal direction to improve the guiding effect.
[0039] Specifically, such as Figures 1 to 3 As shown, in this embodiment, the guide protrusion 2 can be formed in the shape of a strip. The upper surface of the guide protrusion 2 is formed as a guide surface, which can be inclined from top to bottom towards the horizontal exhaust port 120 to guide the flow towards the horizontal exhaust port 120. During the flow of the refrigerant gas towards the horizontal exhaust port 120, it will be split when passing the top of the second exhaust pipe section 13, so that part of the refrigerant gas is discharged from the horizontal exhaust port 120 and the other part is discharged from the vertical exhaust port 130.
[0040] In addition, such as Figures 1 to 3 As shown, according to a second aspect of the present invention, a scroll compressor 4 is provided. The scroll compressor 4 includes a casing 40, a frame 41, a motor 42, and a flow-through exhaust passage structure as described above. The frame 41 can be welded to the inner wall of the casing 40, and a gas passage 410 is formed between the frame 41 and the casing 40. The inlet 110 of the flow-through exhaust passage structure is located directly below the gas passage 410 to receive refrigerant gas discharged from the bottom end of the gas passage 410. A motor 42 is also installed inside the casing 40, located below the flow-through exhaust passage structure. The motor 42 has an annular winding 420, and a vertical exhaust port 130 of the flow-through exhaust passage structure is sandwiched between the winding 420 and the casing 40, allowing the refrigerant gas flowing from the vertical exhaust port 130 to flow through the winding 420.
[0041] Further optimized, such as Figures 1 to 3 As shown, the scroll compressor 4 may further include an exhaust pipe 43, which connects to the interior of the casing 40. Preferably, the exhaust pipe 43 and the surrounding flow exhaust passage structure can be arranged on opposite sides of the casing 40 to increase the path of refrigerant gas flow, thereby improving the oil separation effect. The refrigerant gas discharged from the vertical exhaust port 130 needs to pass through the winding 420 to reach the exhaust pipe 43, so that the refrigerant gas can have sufficient contact with the winding 420.
[0042] During use, the flow-around exhaust passage structure can play an oil separation effect. The horizontal exhaust port 120 of the flow-around exhaust passage structure can effectively increase the contact and impact of the refrigerant gas with the exhaust passage body 1 and the tube shell 40, and can separate the refrigerant gas from the oil liquid refrigerant oil under the action of centrifugal force. The vertical exhaust port 130 of the flow-around exhaust passage structure can guide the refrigerant gas to the winding 420, so that the refrigerant gas fully contacts the winding 420, which increases the separation efficiency of the refrigerant oil, and can cool the winding 420 of the motor 42, thereby effectively reducing the oil circulation rate of the scroll compressor 4.
[0043] Finally, it should be noted that the above-described embodiments are merely specific implementations of the present application, which are used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily think of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed by the present application, or make equivalent replacements to some technical features.
