It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This utility model embodiment provides an asphalt cooling pipeline, such as Figures 1-8 As shown, the asphalt cooling pipeline includes:

[0034] Central shaft assembly 100 and several sets of condenser assemblies 200 disposed on the circumferential side of central shaft assembly 100;

[0035] The central shaft assembly 100 also includes a central shaft 120, the central shaft 120 has a pipe connection chamber 121 inside, the outer wall of the central shaft 120 has a number of arc-shaped connection surfaces 122, the central shaft 120 has a liquid inlet channel and a liquid outlet channel, and the liquid inlet channel and the liquid outlet channel extend into the pipe connection chamber 121;

[0037] The condenser tube 220 is provided with a water inlet connector at one end and a water outlet connector at the other end. The water inlet connector and the water outlet connector extend through the condenser cylinder 210 and into the interior of the central shaft 120. The pipe connection compartment 121 is provided with two sets of multi-channel connectors 130.
