[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] See Figure 1 as well as Figure 2 Specific Embodiment 1: An L-shaped cold water jacket includes an inner tube 1 and an outer tube, with circumferentially arranged support columns 2 fixed between the inner tube 1 and the outer tube. Both ends of the inner tube 1 extend beyond the length of the outer tube, and flanges 4 are welded to both ends of the inner tube 1. The inner tube 1 has an L-shaped bend structure. The outer tube also has an L-shaped bend structure, with hemispherical plugs 34 welded to both ends. The hemispherical plugs 34 have through-holes that pass through the inner tube 1, and these through-holes are welded to the inner tube 1. Installation openings are provided on the sidewalls of both ends of the outer tube, and welding sleeves 5 are welded to these openings to connect the gap between the inner tube 1 and the outer tube. This invention optimizes the pipe structure by using support columns between the inner tube 1 and the outer tube to ensure the strength of both. The hemispherical plugs facilitate the closure of the axial end of the outer tube while simultaneously enabling connection with the inner tube 1. When the medium transported by the inner pipe 1 needs to be cooled, coolant is introduced through the docking sleeve to achieve the cooling of the medium transported by the inner pipe 1.

[0037] The inner tube 1 includes a first inner straight tube section, an inner arc-shaped tube section, and a second inner straight tube section connected in a bent-form sequence; the outer tube includes a first outer straight sleeve 31, an outer arc-shaped sleeve 32, and a second outer straight sleeve 33 welded together in sequence; hemispherical plugs 34 are welded and fixed on both the first outer straight sleeve 31 and the second outer straight sleeve 33; the first outer straight sleeve 31 is fitted around the first inner straight tube section; the outer arc-shaped sleeve 32 is fitted around the inner arc-shaped tube section; and the second outer straight sleeve 33 is fitted around the second inner straight tube section. This facilitates the sequential insertion and welding of the first outer straight sleeve 31, the outer arc-shaped sleeve 32, and the second outer straight sleeve 33 into different positions.

[0038] The outer wall of the outer tube is covered with insulating cotton. The area of ​​the inner tube 1 extending out of the outer tube is also covered with insulating cotton.

[0039] Four circumferentially arranged support columns are fixed to the outer wall of the outer sleeve. The inner side of the support columns abuts against the outer wall of the inner tube. Alternatively, circumferentially arranged support columns are welded to and fixed to the inner wall of the first outer straight sleeve 31; circumferentially arranged support columns are welded to and fixed to the inner wall of the second outer straight sleeve 33. This facilitates the limiting of the first outer straight sleeve 31 and the second outer straight sleeve 33 during insertion. Alternatively, circumferentially arranged support columns are welded to and fixed to the outer wall of the first inner straight tube section; circumferentially arranged support columns are welded to and fixed to the outer wall of the second inner straight tube section. This facilitates the relative limiting of the inner tube 1 and the outer sleeve.

[0040] The support column 2 is fixedly installed at the connection between the outer arc-shaped sleeve and the second outer straight sleeve 33.

[0041] The first inner straight pipe section is set vertically, and the second inner straight pipe section is set horizontally.

[0042] The first outer straight sleeve 31 is set vertically, and the second outer straight sleeve 33 is set horizontally. The connecting sleeve 5 connected to the first outer straight sleeve 31 is set horizontally. The connecting sleeve 5 connected to the second outer straight sleeve 33 is set horizontally and is directly opposite the second inner straight pipe section.

[0043] The length of the first inner straight pipe section is less than the length of the second inner straight pipe section; a support column is sandwiched between the outer wall of the second inner straight pipe section and the second outer straight sleeve 33.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
