<p>A cold/thermal flow media supply pipeline with variable cross-section is comprised of a working inner pipe (1), capillary tubes or pieces (2), an outer pipe (3) , a connecting bracket (4) for connecting the inner pipe (1) and the outer pipe (3), and a variable cross-section cavity (5) between the inner pipe (1) and the outer pipe (3).The capillary tubes or pieces (2) are constructed on the outer wall of the inner pipe (1) and used to adjust the temperature in the cavity (5) . The cavity (5) not only adjusts the temperature surrounding the cold/thermal flow but also prevents the carbonization and aging of the thermal-protective layer (6) of the outer pipe (3) easily caused by directly contacting with the cold/thermal flow media. The pipe can be used to supply cold/thermal flow inside/outside room.</p> |
