Embodiment
[0049] The invention mainly adds a buffer to the pipeline of the external unit of the air conditioner. By adding a buffer to the elbow of the pipeline with a small test margin, the pipeline of the external unit that cannot be improved in design can reduce the shutdown stress of the pipeline during shutdown and avoid high-load shutdown. Manage problems and user troubles, and improve user experience.
[0050] The present invention adopts the buffer that can be obtained by self-design, and the design diagram is as follows figure 1 , 1 is high-pressure gas, 2 is the shell, the material is stainless steel, and 3 is high-temperature and high-pressure resistant film material, which can expand under the action of force. Pipelines with buffers such as figure 2 As shown, 4 is the pipeline of the external unit of the air conditioner, and 5 is the buffer. Under normal circumstances, the gas in the cavity is high pressure, and it is welded in front of the elbow of the pipeline of the exter...

Abstract
The invention belongs to the technical field of air conditioners, and discloses a method for alleviating pipeline vibration stress, a buffer, a bend pipe structure and its application. Buffer to relieve pipeline shutdown stress. The buffer is provided with a shell, which is made of stainless steel; the shell is filled with high-pressure gas; the sealing part of the shell is made of high-temperature and high-pressure resistant film material, which can expand under the action of force. The invention mainly adds a buffer to the pipeline of the external unit of the air conditioner. By adding a buffer to the elbow of the pipeline with a small test margin, the pipeline of the external unit that cannot be improved in design can reduce the shutdown stress of the pipeline during shutdown and avoid high-load shutdown. Manage problems and user troubles, and improve user experience. The invention can effectively reduce the stress and strain when the air conditioner is working under a high-load condition, and can achieve 95% stress absorption.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for alleviating the vibration stress of pipelines, a buffer, an elbow structure and applications. Background technique [0002] At present, with the development of the economy, people's living standards have been improved, and the demand for air conditioners is also increasing. The usage habits of air conditioners in different regions are different, and the environmental load is different. The user has brought a lot of trouble. The broken pipe is mainly due to the large operating load of the air conditioner and the large vibration of the pipeline. Warranty, to bring troubles to users. Therefore, there is an urgent need for a method for alleviating the shutdown stress of pipelines, avoiding the problem of broken pipes, and improving user experience. [0003] Through the above analysis, the existing problems and defects of the prior art are as follow...
