Description

Technical Field

[0001] The utility model relates to the technical field of double-layer cooling pipe groups, in particular to a double-layer cooling pipe group kit with opposite flow directions. Background Art

[0002] Against the backdrop of rapid development in industrial production and science and technology, the cooling tube assembly, as an important component of the heat exchange and heat dissipation system, has a direct impact on the operational stability and service life of the entire equipment due to its performance and efficiency. The cooling tube assembly itself is made of thermally conductive material, and heat is exchanged with the outside world by introducing heat exchange medium into it.

[0003] Traditional cooling tube assemblies often adopt a single-layer, straight-through design, where the cooling medium and the fluid to be cooled exchange heat in the same direction. While this approach is simple and direct, it has limitations in improving heat exchange efficiency and cooling effectiveness. First, in a single-layer, straight-through cooling tube assembly, the contact time and contact area between the cooling medium and the fluid to be cooled are limited, making it difficult to further improve heat exchange efficiency. Furthermore, due to the uneven temperature distribution of the fluid as it flows through the pipe, localized overheating or undercooling is prone to occur, especially at bends or cross-sectional changes in the pipe, affecting the overall cooling effect. In view of this, we propose a double-layer cooling tube assembly with opposite flow directions. Utility Model Content
