A water inlet mechanism is provided at one end of the tank body 1, and a water outlet mechanism is provided at the other end. Through the high-temperature resistant design of the tank body 1 and the heat-resistant layer 11 of the tubes, the high-temperature resistance of the heat exchanger can be effectively increased, preventing damage under high-temperature conditions. A first water inlet pipe 3 is provided at the top of one end of the tank body 1, with a first tube flange fixedly connected to the top of the first water inlet pipe 3. A first water outlet pipe 4 is provided at the bottom of the other end of the tank body 1, with a second tube flange fixedly connected to the bottom of the first water outlet pipe 4. The first inlet pipe 3 and the first outlet pipe 4 are designed to ensure good sealing and connection, preventing leakage during heat exchange and improving system stability. The fixing mechanism includes multiple abutment seats 14 symmetrically fixed on the inner walls of both ends of the tank 1 and a support plate 12 that cooperates with the multiple abutment seats 14. Each abutment seat 14 has a first threaded hole, and the support plate 12 has a second threaded hole corresponding to the first threaded hole. Fixing bolts 15 are inserted into the first threaded hole and the second threaded hole, and fixing nuts are threaded to the ends of the fixing bolts 15. Through the design of the fixing mechanism, the tubes 10 can be stably fixed in the tank 1, preventing structural deformation under high temperature or high pressure conditions and ensuring the safety of the heat exchanger.

[0021] In this utility model, the support plate 12 has pipe holes for passing through the tubes 10, and water outlets are provided on the periphery of the support plate 12. A rubber gasket 13 is provided at the contact end between the support plate 12 and the tank body 1. The pipe holes and water outlets on the support plate 12 enable better fluid flow and distribution, effectively improving heat exchange efficiency and ensuring sufficient heat exchange within the heat exchanger.

One end of the water inlet cover 6 is provided with a first flange 5 bolted to the first connecting flange. A first bolt 9 passes through the hole in the first connecting flange and the first flange 5, and the end of the first bolt 9 is threaded with a second... A nut is provided at one end of the water inlet cover 6, and a second water inlet pipe 7 is provided at one end.

Through the effective structure of the water outlet mechanism, the smooth water outlet can be ensured, blockage can be prevented, and the overall water flow capacity of the heat exchanger can be improved.

[0022] Working principle: When using this utility model, the fluid to be heated, such as hot water or other liquid, is added into the heat exchanger tank 1 through the first inlet pipe 3. The fluid should be within an appropriate temperature range before entering the tank to ensure that it will not cause impact on the equipment during startup. The heated fluid undergoes heat exchange through the tubes 10. The tubes 10 are supported by the support plate 12. The design of the water outlet ensures that the fluid flows evenly in the tubes, effectively improving the heat exchange efficiency. During the heat exchange process, the temperature of the fluid inside the tank 1 gradually increases, while the required low-temperature fluid enters the heat exchanger through the water inlet shroud 6 to absorb heat. When the heat exchange reaches the predetermined effect, the fluid heated by the tubes 10 is discharged through the first outlet pipe 4. The connection between the outlet and the second flange is kept sealed to ensure smooth water flow and prevent leakage.
