Therefore, they should not be construed as limitations on this utility model.

[0026] Example: An energy-saving device for heat recovery, such as Figures 1-4 As shown, the device includes a support base 1, a housing 2 at the upper end of the support base 1, a high-efficiency heat exchange component inside the housing 2, the high-efficiency heat exchange component including a spiral heat pipe 3 and a heat sink 4, the spiral heat pipe 3 inside the housing 2, the heat sink 4 wrapped around the outside of the spiral heat pipe 3, a temperature sensor 5 on the outside of the heat sink 4, a high-temperature gas inlet pipe 6 at the upper end of the housing 2, a low-temperature gas outlet pipe 7 at the upper end of the housing 2, and a first valve 8 in the middle of the high-temperature gas inlet pipe 6.

[0027] like Figures 1-5As shown, a high-temperature gas outlet pipe 9 is provided at the right end of the housing 2, and a low-temperature gas inlet pipe 10 is provided at the lower right corner of the housing 2. A second valve 11 is provided in the middle of the low-temperature gas inlet pipe 10. The spiral heat pipe 3 is made of copper, which has good thermal conductivity and can quickly transfer heat. The heat sink 4 is made of aluminum sheet, which increases the contact area with the gas and accelerates heat exchange. A controller 12 is provided at the right end of the housing 2, and a control interface 13 is provided at the right end of the controller 12. The controller 12 is electrically connected to the temperature sensor 5, the first valve 8, and the second valve 11. High-temperature gas (such as industrial waste gas, air conditioning waste heat, etc.) is supplied to the housing 2. High-temperature gas enters the spiral heat pipe 3 through the high-temperature gas inlet pipe 6 and enters the spiral heat pipe 3 under the control of the first valve 8. The spiral pipe extends the residence time and flow path of the high-temperature gas in the pipe. At the same time, low-temperature gas enters the shell 2 from the low-temperature gas inlet pipe 10 and enters the shell 2 under the control of the second valve 11. It comes into full contact with the spiral heat pipe 3 and the heat sink 4. As the high-temperature gas flows in the spiral heat pipe 3, heat is transferred to the low-temperature gas through the copper spiral heat pipe 3 and the aluminum heat sink 4, realizing heat exchange. After absorbing heat, the low-temperature gas is discharged from the low-temperature gas outlet pipe 7 and can be used to preheat air, water, etc.

[0028] like Figures 1-5 As shown, an insulation layer 14 is provided on the outer side of the housing 2, and a protective layer 15 is provided on the outer side of the insulation layer 14. The insulation layer 14 is made of rock wool or polyurethane material, and the protective layer 15 is made of corrosion-resistant metal material, which can effectively protect the insulation layer 14 and extend the service life of the device. A slot 16 is provided at the front end of the housing 2, and a movable door 18 is provided at the slot 16. A rubber sealing ring 17 is provided between the slot 16 and the movable door 18. The housing 2 and the movable door 18 are connected by a hinge 19. The front end is equipped with a convenient handle 20. The housing 2 and the movable door 18 are locked together by a lock cylinder 21. The lower end of the support base 1 is equipped with a support column 22. The lower end of the support column 22 is equipped with a rubber anti-slip ring pad 23. The inside of the support column 22 is equipped with an electric push rod 24. The transmission end of the lower end of the electric push rod 24 is equipped with a universal wheel 25. The controller 12 is electrically connected to the electric push rod 24. The electric push rod 24 pushes the universal wheel 25 downward, which allows people to move the device more quickly.

[0029] Working Principle: During operation, high-temperature gas (such as industrial waste gas, air conditioning waste heat, etc.) enters the spiral heat-conducting pipe 3 through the high-temperature gas inlet pipe 6 and under the control of the first valve 8. The spiral pipe extends the residence time and flow path of the high-temperature gas inside the pipe. At the same time, low-temperature gas enters the housing 2 through the low-temperature gas inlet pipe 10 and under the control of the second valve 11, making full contact with the spiral heat-conducting pipe 3 and the heat sink 4. As the high-temperature gas flows inside the spiral heat-conducting pipe 3, heat is transferred to the low-temperature gas through the copper spiral heat-conducting pipe 3 and the aluminum heat sink 4, achieving heat exchange. After absorbing heat, the low-temperature gas is discharged from the low-temperature gas outlet pipe 7, which can be used to preheat air, water, etc. After releasing heat, the high-temperature gas is discharged from the high-temperature gas outlet pipe 9. During the heat exchange process, the temperature sensor 5 monitors the temperature of the heat exchange area in real time and transmits the data to the controller 12. If the temperature does not reach the preset value, the controller 12 controls the first valve 8 and the second valve 11 to increase the opening, increase the flow rate of the high-temperature gas and the low-temperature gas, and accelerate the heat exchange. If the temperature is too high, the controller 12 controls the valves to reduce the flow rate, ensuring stable and efficient operation of the heat recovery process.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
