These methods increase the system's energy consumption and are not conducive to energy conservation and emission reduction. Therefore, there is a need to provide a heat pipe heat exchanger that can automatically regulate exhaust gas temperature to solve the above problems. Utility Model Content

[0009] The temperature sensor (20) is fixed at one end of the smoke outlet pipe (16) near the smoke outlet hood (14). The disc (21) is fixed inside the smoke outlet pipe (16). The support pipe (22) is welded to the side of the disc (21). The first limiting hole (23) is opened on both sides of the support pipe (22).

[0011] Furthermore, the first rack (251) and the second rack (261) mesh on the corresponding sides of the gear (28), and the second rack (261) is movably connected to the inner side of the U-shaped support plate (250).

[0012] Furthermore, the flue gas heat exchanger also includes a water inlet pipe, a water outlet pipe, a flue hood, and a flue pipe. One end of the U-shaped support plate (250) is movably connected to the two first limiting holes (23), and the connecting block (260) is movably connected to the second limiting hole (24).

[0013] Furthermore, the flue gas heat exchanger also includes an inlet pipe (11), an outlet pipe (12), a flue gas hood (13), and a flue gas inlet pipe (15).

[0014] Furthermore, the inlet pipe (11) and outlet pipe (12) are fixed at the upper and lower ends of the side of the heat exchanger body (10) and are connected through the heat pipe inside the heat exchanger body (10).

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] I. This utility model, through the setting of an adjustment component, allows for the setting of the exhaust gas temperature. When the temperature sensor detects that the temperature is too high or too low, the motor starts, driving the gear to rotate, which in turn drives the first rack and second rack to move relative to or away from each other. This causes the U-shaped baffle on the U-shaped support plate and the straight baffle on the connecting block to move relative to or away from each other. The length of the flue gas flow channel formed between the U-shaped baffle and the straight baffle changes, thereby changing the flue gas flow velocity through the center of the disc into the support tube. This, in turn, changes the time the flue gas stays in the heat exchanger body. A longer flue gas stay time results in a lower temperature, and a shorter flue gas stay time results in a higher temperature. This design adjusts the exhaust gas temperature by changing the flue gas flow velocity. It has a simple structure and is easy to install.

[0021] II. In this utility model, the positioning components are set to install the disc and the internal parts of the support tube. Holding the support tube, the disc is pushed into the smoke outlet pipe, and the first through hole is aligned with the limiting post on the fixing plate. Then, the bolt is passed through the second through hole and rotated to fix it to the groove on the disc. This setting facilitates the quick installation of the disc and improves the efficiency of installation and maintenance. Attached Figure Description

[0033] Please see Figure 1-5 As shown, this embodiment is a heat pipe heat exchanger capable of automatically adjusting the exhaust gas temperature, comprising:

[0034] The flue gas heat exchanger includes a heat exchanger body 10, a flue hood 14, and a flue pipe 16. The flue hood 14 is fixed to the side of the heat exchanger body 10, and the flue pipe 16 is welded to the other end of the flue hood 14.

[0035] The flue gas heat exchanger also includes an inlet pipe 11, an outlet pipe 12, an inlet hood 13, and an inlet pipe 15. The inlet pipe 11 and the outlet pipe 12 are fixed to the upper and lower ends of the side of the heat exchanger body 10 and are connected through the heat pipe inside the heat exchanger body 10. The inlet hood 13 is fixed to the end of the heat exchanger body 10 away from the outlet hood 14, and the inlet pipe 15 is welded to the other end of the inlet hood 13.

[0036] The heat exchanger body 10 is used to convert the heat in the flue gas out. The inlet pipe 11 introduces cold water into the heat exchanger body 10. The outlet pipe 12 is used to discharge the hot water after absorbing the heat. The inlet hood 13 and the outlet hood 14 serve a protective function. The inlet pipe 15 introduces flue gas into the heat exchanger body 10. The outlet pipe 16 is used to discharge the flue gas after heat exchange.

[0037] The adjustment assembly includes a temperature sensor 20, a disc 21, a support tube 22, a first limiting hole 23, a second limiting hole 24, a U-shaped baffle 25, a U-shaped support plate 250, a first rack 251, a straight baffle 26, a connecting block 260, a second rack 261, a motor 27, and a gear 28. The temperature sensor 20 is fixed to one end of the smoke outlet pipe 16 near the smoke outlet hood 14. The disc 21 is fixed inside the smoke outlet pipe 16. The support tube 22 is welded to the side of the disc 21. The first limiting hole 23 is formed on both sides of the support tube 22. The second limiting hole 24... 24 is opened on both sides of the support tube 22 and located between the two first limiting holes 23. The U-shaped baffle 25 passes through and is movably connected to the upper end of the support tube 22. The straight baffle 26 passes through and is movably connected to the lower end of the support tube 22. One end of the U-shaped support plate 250 is fixed to the side of the U-shaped baffle 25. The first rack 251 is fixed to the inner side of the U-shaped support plate 250. The connecting block 260 is fixed to the side of the straight baffle 26. The second rack 261 is fixed to the side of the connecting block 260. The motor 27 is fixed to the side of the support tube 22. The gear 28 is fixed to the output end of the motor 27.

[0038] The first rack 251 and the second rack 261 mesh on the corresponding sides of the gear 28, and the second rack 261 is movably connected to the inner side of the U-shaped support plate 250;

[0039] One end of the U-shaped support plate 250 is movably connected to the two first limiting holes 23, and the connecting block 260 is movably connected to the second limiting hole 24;

[0040] Temperature sensor 20 is a PT100 platinum resistance temperature sensor. Disk 21 acts as a block to prevent flue gas from flowing out from the outside of support tube 22. Support tube 22 provides support. First limiting hole 23 and second limiting hole 24 provide limiting and support functions. U-shaped baffle 25 and straight baffle 26 are used to adjust the length of the flue. U-shaped support plate 250 provides support. Connecting block 260 provides support. Motor 27 provides power source. Gear 28 is used to transmit power. First rack 251 and second rack 261 are used to convert power.

[0041] Working principle:

[0042] Once the exhaust temperature is set, when the temperature sensor 20 detects that the temperature is too high or too low, the motor 27 starts, driving the gear 28 to rotate. This, in turn, drives the first rack 251 and the second rack 261 to move relative to or away from each other. This causes the U-shaped baffle 25 on the U-shaped support plate 250 and the straight baffle 26 on the connecting block 260 to move relative to or away from each other. As a result, the length of the flue gas flow channel formed between the U-shaped baffle 25 and the straight baffle 26 changes, which in turn causes the flue gas flow velocity to change as it flows through the middle of the disc 21 into the support tube 22. Consequently, the time that the flue gas stays in the heat exchanger body 10 changes. A longer flue gas stay time results in a lower temperature, while a shorter flue gas stay time results in a higher temperature.

[0043] This step adjusts the exhaust temperature by changing the flue gas flow rate; it has a simple structure and is easy to install.

[0044] Please see Figure 2-3 This embodiment, based on the above embodiments, further includes:

[0045] The positioning assembly includes a fixing plate 30 and a limiting post 31. The fixing plate 30 is welded to the inside of the smoke outlet pipe 16, and the limiting post 31 is welded to the side of the fixing plate 30.

[0046] The positioning assembly also includes a first through hole 32, a second through hole 33 and a groove 34. The first through hole 32 is opened on the disc 21 and the disc 21 is inserted into the limiting post 31 through the first through hole 32. The second through hole 33 is opened on the smoke outlet pipe 16 and the groove 34 is opened on the outside of the disc 21. The second through hole 33 and the groove 34 are connected by bolts.

[0047] The fixing plate 30 provides support, the limiting post 31 and the first through hole 32 provide limiting, and the second through hole 33 and the groove 34 provide connection.

[0048] Working principle:

[0049] Install the components inside the disc 21 and the support tube 22, hold the support tube 22, push the disc 21 into the smoke outlet tube 16, and push the first through hole 32 into the limiting post 31 on the fixing plate 30. Then, use a bolt to pass through the second through hole 33 and rotate it to fix it to the groove 34 on the disc 21.

[0050] This step facilitates the quick installation of the adjustment disc 21, improving installation and maintenance efficiency.
