Abstract
Vibration absorption tubing and a manufacturing method thereof. The manufacturing method includes: a solder placement step including: placing solder at solder placement portions in an inner cavity of an adaptor; a pipe fitting step including: fitting a corrugated pipe and the adaptor respectively to adaptor matching portions at corresponding sides of the adaptor, to communicate an adaptor inner cavity with an inner cavity of the corrugated pipe and inner cavities of external connection tubing; and fixing or limiting positions of the corrugated pipe, the adaptor, and the external connection tubing to obtain a tubing assembly; and a component brazing step including: performing furnace brazing on the tubing assembly of the external connection tubing to obtain a main vibration absorption tubing. The vibration absorption tubing has favorable brazing consistency, enhancing connection reliability of components.
