Abstract

The application provides a pipe, which comprises a deformable pipe section, the deformable pipe section comprises a plurality of inner convex sections, the plurality of inner convex sections are arranged along the axial direction of the deformable pipe section, the inner convex sections protrude to the inside of the pipe, and the opposite wall surfaces of two adjacent inner convex sections are in contact in at least part of the deformable pipe section. In the application, the deformable pipe section is arranged so that the pipe no longer depends on the ductility of the material itself when being bent, but realizes the adjustment of the direction by deformation; and the opposite wall surfaces of two adjacent inner convex sections are in contact in at least part of the deformable pipe section, so that the amplitude of the concave-convex of the inner wall is reduced in at least part of the deformable pipe section, a relatively smooth flow channel is formed, the turbulence and vibration generated when the refrigerant flows through these areas are significantly reduced, the stability of the refrigerant flow is improved, and the generation of noise is reduced.
