Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a compressor exhaust pipeline and a compressor. Background Art

[0002] The compressor is the power core of the refrigeration system, providing power for the refrigeration system and completing the periodic suction, compression and exhaust process of the refrigerant.

[0003] The piping system is a channel for transporting refrigerant. It is generally made of copper and includes an air intake pipe and an air discharge pipe. The air intake pipe is connected to the air intake port of the compressor, and the air discharge pipe is connected to the exhaust pipe of the compressor. The compressor vibrates greatly during operation, which is directly transmitted to the pipes connected to it, stimulating the vibration of the pipes. The pressure of the exhaust pipe is high, the pressure pulsation is large, and the vibration is more intense. At the same time, with the development of frequency conversion in the refrigeration industry, the frequency conversion compressor has many operating frequencies, which can easily stimulate the mode of the pipe system to cause resonance, making vibration control difficult, resulting in a reduced life of the refrigeration system or fatigue fracture of the pipe.

[0027] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-3 As shown, an embodiment of the present invention proposes a compressor exhaust pipeline, comprising: a muffler 2, an exhaust pipe 1 and a mounting member 4, wherein the muffler 2 is connected to the exhaust pipe 1, and one end of the exhaust pipe 1 is connected to the output end of the compressor; wherein the mounting member 4 comprises: two first clamping arms 401 and two second clamping arms 402, one end of the two first clamping arms 401 is respectively connected to one end of the two second clamping arms 402 through an intermediate section 403, the ends of the two first clamping arms 401 away from the intermediate section 403 are connected to each other through a fastening member, the two intermediate sections 403 are locked by a locking member, the two first clamping arms 401 are used to clamp on the side wall of the compressor body 3, and the two second clamping arms 402 are used to clamp the muffler 2.

[0029] The two first clamping arms 401 are connected to the two second clamping arms 402 through the middle section 403. At the same time, the two first clamping arms 401 are clamped on the side wall of the compressor body 3, and the two second clamping arms 402 clamp the muffler 2 located on the exhaust pipe 1, thereby greatly limiting the vibration of the muffler 2, and also reducing the vibration amplitude of the exhaust pipe 1, reducing the vibration stress of the pipeline, thereby preventing the exhaust pipe 1 from being damaged, and increasing the service life of the exhaust pipe 1. It can also avoid the disadvantage of large deformation of the exhaust pipe 1 when the compressor falls or collides during transportation.

[0030] As a preferred example, Figure 2 As shown, the first clamping arm 401 and the two second clamping arms 402 are both semicircular, and the locking member can be a bolt 407.

[0031] As an example, Figure 4As shown, the fastening member includes: a connecting page 405 and an installation page 404 respectively arranged at one end of the two first clamping arms 401 away from the middle section 403, wherein the installation page 404 is provided with an installation hole for the connecting page 405 to pass through, and one end of the connecting page 405 passing through the installation hole is provided with a bending portion 406 fastened to the installation page 404, so that the two first clamping arms 401 can be easily disassembled and connected. Figure 2 As shown, a protective sleeve 5 is provided between the muffler 2 and the two second clamping arms 402 . The protective sleeve 5 is made of rubber material. Preferably, the thickness of the protective sleeve 5 is greater than 2 mm to prevent the outer shell of the muffler 2 from being worn during vibration.

[0032] As an embodiment, the exhaust pipe 1 includes: a vertical section 101, a downward section 103 and a connecting section 104, wherein the vertical section 101 is used to connect to the output end of the compressor, the vertical section 101 and the downward section 103 are connected through a transition section 102, one end of the downward section 103 is connected to the input end of the muffler 2, and the connecting section 104 is also connected to the output end of the muffler 2 through the transition section 102. The exhaust pipe 1 is designed in a segmented manner, and the muffler 2 is installed in the downward section 103. The exhaust pipe 1 as a whole is formed into a multi-section bent shape, which is beneficial to improve the stability of the pipeline. Even if a collision occurs, only one section of the pipeline will be damaged, which is convenient for the maintenance of the exhaust pipe 1. The transition section 102 can be a straight section, or it can be composed of multiple straight sections spliced ​​together, or it can be an arc section.

[0033] Preferably, both ends of the two transition sections 102 are provided with bending parts, and the bending radius of the bending part is greater than twice the diameter of the pipeline of the bending part, so as to avoid stress concentration at the bend of the exhaust pipe 1.

[0034] As an example, Figure 6 as well as Figure 7 As shown, the silencer 2 includes: a shell 201 and connecting pipes 202 arranged on both sides of the shell 201, the interior of the shell 201 is an expansion chamber 203, one end of the two connecting pipes 202 are respectively inserted into the expansion chamber 203, and the ends of the two connecting pipes 202 inserted into the expansion chamber 203 are provided with a bending section 204 and an extension section 205, and the two extension sections 205 are staggered. The design of the bending section 204 increases the length of the end of the connecting pipe 202 inserted into the expansion chamber 203, thereby increasing the expansion ratio of the expansion chamber 203 from the side, that is, the longer the length of the inserted pipe (the bending section 204 and the extension section 205) in the expansion chamber 203, the greater the low-frequency muffling amount. Compared with the existing linear inserted pipe, the advantage is that, through the design of the silencer 2, the low-frequency noise can be better eliminated without increasing the length of the silencer 2 itself, thereby improving the muffler effect of the compressor.

[0035] At least one filter 206 is also provided in the expansion cavity 203. Each filter 206 is sealed and connected to the inner wall of the expansion cavity 203. The two extension sections 205 pass through each filter 206 respectively. The filter 206 is designed to filter impurities such as dust and particulate matter in the air.

[0036] like Figure 5 As shown, a compressor comprises the compressor exhaust pipe 1.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
