[0029] Please refer to Figures 1-2 Flange plates are symmetrically welded at both ends of the pipe body 1 to seal the liquid storages 14.

[0030] It should be noted that the flange plates are welded at both ends of the pipe body 1, can effectively seal the liquid storages 14, prevent the liquid from leaking from the liquid storages 14, ensure that the liquid fully circulates in the liquid storages 14, and improve the efficiency of temperature adjustment.

[0031] At the same time, the flange is not only used for sealing the liquid tank 14, but also can connect and fix the pipe body 1, and can connect multiple pipes together through the flange to form a complete conveying system.

[0032] Please refer to Figure 2 The positioning plate 13 is provided with through holes for the liquid to pass through.

[0033] It should be noted that the through holes can make the liquid uniformly distributed in the liquid tank 14 between the inner pipe 11 and the outer pipe 12, avoid local retention or poor flow of the liquid, and ensure uniform temperature distribution in the liquid tank 14. In this way, the liquid can uniformly wrap the inner pipe 11, ensuring that the contact area between the liquid and the inner pipe 11 is maximized, thereby improving the temperature regulation effect.
