Abstract
Description
Technical Field
[0001] This utility model relates to the field of compressor technology, specifically to a compressor pipeline layout structure. Background Technology
[0002] Figure 1 The diagram shows a schematic of the piping layout of a compressor in the prior art. The piping layout between the compressor and the distributor is one of the main structural designs of the cooling equipment. In order to reduce collisions and motion interference during transportation, the existing piping layout between the compressor 1 and the distributor 2 generally places the four-way valve 32 above the compressor 1. That is, the height of the four-way valve 32 is higher than the top of the compressor 1, which results in a long piping layout, which is prone to vibration and affects the working stability of the compressor. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a compressor pipeline layout structure. By adjusting the setting height of the four-way valve and coordinating the pipeline layout, the vibration risk of the pipeline structure between the compressor and the distributor is reduced, thereby improving the working stability of the compressor.
[0004] This utility model provides a compressor pipeline layout structure, which is applied between the compressor and the distributor. The pipeline layout structure includes: a four-way valve and several pipes.
[0005] The four-way valve is located on the upper part of the compressor, and the bottom end of the four-way valve is connected at a height lower than the top of the compressor.
[0006] Furthermore, the height of the compressor is L, the height of the four-way valve is H, and the constraint relationship between L and H is: 1 / 2L≤H≤L.
[0007] Furthermore, the horizontal distance between the pipes in the pipeline layout structure and the base bolts of the compressor is D1, and the value range of D1 is: D1≥30mm.
[0008] Furthermore, the vertical distance between the pipes in the pipeline layout structure and the base bolts of the compressor is D2, and the value range of D2 is: D2≥15mm.
[0009] Furthermore, the pipe located below the four-way valve is configured as a U-shaped pipe.
[0010] This utility model provides a compressor pipeline layout structure. By lowering the position of the four-way valve to the area corresponding to the upper part of the compressor structure, the pipeline connection length of the four-way valve is reduced. Combined with the pipeline layout structure, this effectively reduces the vibration risk of the pipeline structure between the compressor and the distributor, and improves the working stability of the compressor.

[0014] Figure 3 This is a schematic diagram showing the magnitude of pipeline stress of the compressor at different operating frequencies in an embodiment of this utility model. Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Figure 2 A schematic diagram of the compressor piping layout structure in an embodiment of this utility model is shown. Figure 3 The diagram shows the magnitude of pipeline stress of the compressor at different operating frequencies in an embodiment of the present invention. The pipeline layout structure is applied between the compressor 1 and the distributor 2. The pipeline layout structure 3 includes: a four-way valve 32 and several pipes 31. The several pipes 31 include an intake pipe connected to the intake end of the compressor 1 and an outlet pipe connected to the outlet end of the compressor 1. The four-way valve 32 is located on the upper part of the compressor 1, and the height of the bottom end of the four-way valve 32 is lower than the height of the top of the compressor 1.
[0017] By reducing the installation height of the four-way valve 32 and shortening the arrangement distance between the four-way valve 32 and the compressor 1, the length of the pipeline design can be reduced, and the risk of vibration loss in the pipeline structure can be reduced.
[0018] Specifically, the height of the compressor 1 is L, and the installation height of the four-way valve 32 is H. The constraint relationship between L and H is: 1 / 2L≤H≤L. That is, the installation position of the four-way valve 32 can be located in the upper part of the compressor 1, which can effectively ensure that there is an effective distance after the pipe exits from the four-way valve 32 for easy pipe routing. Moreover, when the four-way valve 32 meets this height, the vibration generated by the four-way valve 32 during operation can also be effectively distributed to the suction pipe / exhaust pipe and the outlet pipe of the four-way valve 32, reducing the problem of excessive vibration concentration caused by the vibration of the four-way valve 32, which leads to stress concentration.
[0019] Specifically, the horizontal distance between the pipe 31 of the pipeline layout structure 3 and the base bolt of the compressor 1 is D1, and the value of D1 is in the range of D1≥30mm. The vertical distance between the pipe 31 of the pipeline layout structure 3 and the base bolt of the compressor 1 is D2, and the value of D2 is in the range of D2≥15mm. By setting the vertical distance between the pipe 31 of the pipeline layout structure 3 and the base bolt to be ≥15mm and the horizontal distance to be ≥30mm, the problem of collision between the pipeline and the base bolt of the compressor 1 can be avoided when the vibration of the four-way valve 32 or the compressor 1 or the vibration during transportation is transmitted to the pipeline.
[0020] Furthermore, the bottom of the compressor 1 is fixed to the bottom sheet metal by three bolts symmetrically centered on the compressor 1. Since the bolt structure protrudes to a certain height, controlling the distance range can effectively prevent the pipe 31 from colliding with it. At the same time, it can meet the spatial layout requirements between the compressor 1 and the distributor 2, avoid the situation of the pipe 31 being too long, improve the compactness of the pipeline structure design, and effectively improve the space utilization rate between the distributor 2 and the compressor 1.
[0021] Specifically, the pipe 31 located below the four-way valve 32 is configured as a U-shaped pipe. This U-shaped pipe improves the elasticity of the pipe 31 below the four-way valve 32, giving the pipe 31 structure good impact resistance and reducing the risk of impact damage to the pipe 31 structure caused by compressor 1 vibration, thus ensuring good structural stability. Because the height of the four-way valve 32 is reduced and the pipe is shorter, the pipe may be subjected to stress from transmitted vibrations. The pipe exiting the four-way valve 32 connects to the pipe exiting the compressor 1 / distributor 2. The advantage of the U-shape is that vibrations transmitted from the compressor 1 / distributor 2 and the four-way valve 32 can be dispersed to a certain extent in the U-shaped section, thereby reducing stress transmission and improving the reliability of the pipe.
[0022] For further details, please refer to... Figure 3By adjusting the pipeline layout structure 3 between compressor 1 and distributor 2, lowering the setting height of the four-way valve 32, reducing the length of the pipeline 31, and reducing the structural rigidity of the pipeline layout structure 3 through pipeline shape design, the vibration stress problem of the pipeline layout structure 3 under different operating frequencies of compressor 1 can be reduced, and the stress concentration of the pipeline layout structure 3 can be reduced, thereby improving the reliability of the pipeline layout structure 3 between compressor 1 and distributor 2.
[0023] This utility model embodiment provides a compressor 1 pipeline layout structure 3, which adjusts the position of the four-way valve 32 by lowering it, thereby shortening the overall length of the pipeline. Since the existing air conditioning compressor 1 pipeline is generally made of pure copper or brass, and copper is relatively expensive, the current solution is estimated to shorten the pipeline by 40mm, which can effectively reduce the material cost of the pipeline.
[0024] Furthermore, when compressor 1 is operating, compressor 1 / distributor 2 will vibrate. Variable frequency air conditioners have many operating frequency points, and the resonance points of the four-way valve 32 piping assembly are relatively dense. Under the excitation of the fundamental frequency and harmonics, the piping may resonate. The stress generated by the piping under long-term vibration will affect the reliability of compressor 1 piping. This solution adjusts the distance and shape of the piping, which can effectively avoid collisions or reduce the generation of vibration stress, ensuring the reliability of the piping, and also reducing the generation of vibration noise to a certain extent.
[0025] Furthermore, the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
