This structure can ensure that heat is evenly transferred to each part of the heat dissipation plate 4, thereby improving the overall heat dissipation efficiency. The surface of the heat dissipation rib 8 is provided with a coating of a high reflectivity material, which helps to reflect more heat, reduce the accumulation of heat on the surface of the pipe, and further improve the heat dissipation effect.

Finally, the sewer pipe 1 is inserted from bottom to top into the center of the sealing ring 12 located inside the lower connecting sleeve 10 and the lower connecting sleeve 10 is slightly tightened, thereby utilizing the compression force and friction force between the outer surface of the sewer pipe 1 and the inner wall of the center hole to fix the sewer pipe 1 in the sealing ring 12, thereby completing the installation of the sewer pipe 1.
