[0053] The outer tube material of the round tube heating pipe 50 is changed from the traditional aluminum structure to a titanium tube. This improvement can improve the corrosion resistance of the round tube heating pipe 50 in the water chamber. The original aluminum outer tube is prone to corrosion and form cavities after long-term contact with the water flow in the water chamber, eventually leading to leakage. In contrast, titanium is 1.3 times stronger than aluminum alloy while maintaining a low density, making it an indispensable structural material in fields such as the aerospace industry that require lightweight and high-strength materials. Titanium also has good corrosion resistance and can form an oxide film on the surface, effectively preventing corrosion. Even in high-corrosion environments such as seawater, titanium remains stable. Therefore, by using titanium as the outer tube material, the excellent corrosion resistance of titanium is utilized to ensure the integrity of the round tube heating pipe after long-term power aging, thereby effectively preventing leakage and significantly improving the safety of the product.

[0054] In some embodiments, the flange 40 is made of titanium. Titanium flanges can effectively resist corrosion, reducing the risk of flange material wear and corrosion perforation, thereby enhancing the sealing reliability of the water heater. In addition, the use of titanium flanges also helps to reduce the weight of the entire structure.

[0055] Obviously, the above embodiments are only examples for clarity and are not limiting. Based on the above description, those skilled in the art can make other different forms of changes or variations. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
