[0002] The bellows expansion joint is an expansion joint made of a metal bellows. It can expand and contract along the axial direction and also allows a small amount of bending. It is used on the pipeline for axial length compensation. The current bellows compensators are mostly connected with bolts and nuts to fix the bellows compensators to prevent them from moving and expanding during transportation. However, this fixing method is relatively complicated and inconvenient. Therefore, a bellows compensator with heat dissipation function is needed.

[0003] The existing bellows compensator is inconvenient to limit and fix the bellows compensator during transportation when in use, causing it to expand and contract during transportation. It is also inconvenient to dissipate heat when transporting some high-temperature media, causing the temperature of the bellows compensator to be too high, affecting its service life. Therefore, a bellows compensator with a heat dissipation function is urgently needed. Utility Model Content
