Description

Technical Field

[0001] This utility model relates to the field of chimneys, specifically to a metal chimney with excellent heat dissipation performance. Background Technology

[0002] A chimney is a structure primarily used to expel high-temperature flue gas or smoke produced by boilers, furnaces, incinerators, or fireplaces. Its design allows these harmful gases to be safely separated from human habitation areas. Chimneys are typically installed vertically or as close to vertical as possible to allow for smooth gas flow. The internal space of this structure is called a flue. The chimney itself may be made of brick, clay, or metal. The presence of a chimney also facilitates the natural convection of flue gas or exhaust gases, or the forced exhaust system to expel waste outdoors. The height of the chimney affects its effective smoke extraction capacity. In high-altitude areas, chimneys can help reduce the impact of pollutant diffusion on the surrounding environment. Metal chimneys are one type of chimney.

[0003] A search revealed a metal chimney with publication number CN215411935U that is easy to clean. Specifically, it discloses a metal chimney that is easy to clean, including a smoke exhaust device. The smoke exhaust device includes a chimney, which has an outer layer and a metal inner layer. The outer layer has a support plate, and the support plate has a connecting body. The connecting body includes a connecting ring, a side body, and a connection point. The connection point is connected to a running body, which includes a servo motor connected to a drive shaft. The connecting ring has a connecting bracket with a rotation opening. The drive shaft has a drive frame, and the drive frame has a connecting rod connected to a cleaning body, which includes a scraping plate. The advantage of this invention is that the cleaning process of the chimney's inner wall is simple and easy to clean.

[0004] In existing metal chimneys, the high temperature of the smoke itself is transferred through the chimney during smoke circulation. If the metal chimney lacks its own heat dissipation capacity and relies solely on its own heat and the ambient temperature for cooling, long-term use will lead to metal fatigue, increasing the probability of damage. Furthermore, the comparative cases mentioned above did not include other auxiliary heat dissipation methods. As a result, after prolonged use, the metal chimney will be subjected to high temperatures, which may cause the internal pipes to deform due to overheating or even burn out.

[0005] Therefore, it is necessary to invent a metal chimney with excellent heat dissipation performance to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a metal chimney with excellent heat dissipation performance. It achieves superior heat dissipation through an outer chimney body, an outer heat dissipation ring, heat dissipation fins, an inner chimney body, a heat dissipation protective layer, and serpentine cooling pipes. This avoids the problem of high temperatures accumulating inside the inner chimney body and failing to dissipate, leading to metal fatigue, overheating deformation, or even burnout, which can occur when relying solely on the chimney's own heat dissipation capacity. This also ensures the normal emission of smoke from the chimney, improving its overall service life. This addresses the problem in existing metal chimneys where, due to the temperature of the smoke, the high temperature is transferred through the chimney itself during smoke circulation. If the chimney lacks sufficient heat dissipation capacity and relies solely on its own heat and external temperature, long-term use can lead to metal fatigue and increased probability of damage. Furthermore, the aforementioned comparative cases lacked other auxiliary heat dissipation methods, resulting in the internal pipes deforming or even burning out due to overheating after prolonged use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal chimney with excellent heat dissipation performance, including an outer chimney body for providing protection for internal pipes;

[0008] A sliding groove is formed on the outside of the outer chimney body for installing heat dissipation components. A sliding block is movably connected inside the sliding groove. An outer heat dissipation ring is fixedly installed at one end of the sliding block, and heat dissipation fins are fixedly installed on the outside of the outer heat dissipation ring.

[0009] An inner chimney body is located inside the outer chimney body and is used to carry the flow of smoke and dust. The outer surface of the inner chimney body is covered with a heat dissipation protective layer. A serpentine cooling pipe is fixedly installed on the outside of the inner chimney body, and a leak-proof plug is fixedly installed at one end of the serpentine cooling pipe.

[0010] Preferably, a mounting base is fixedly installed at the bottom of the outer chimney body, a stiffening rib is provided above the mounting base, a positioning bolt passes through the top of the mounting base, and a chimney top is fixedly installed at the top of the outer chimney body.

[0011] Preferably, the outer heat dissipation ring is movably connected to the outer chimney body, and the sliding groove is used in conjunction with the sliding block.

[0012] Preferably, the inner chimney body and the heat dissipation protective layer are tightly bonded together, and the material of the heat dissipation protective layer is graphene.

[0013] Preferably, a fixing bolt passes through the exterior of the inner chimney body, and an activated carbon filter is movably connected to one end of the fixing bolt.

[0014] Preferably, an internal fixed filter frame is provided inside the inner chimney body, an upper connecting filter screen is fixedly installed above the internal fixed filter frame, and an inner filter bag is provided inside the internal fixed filter frame.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model is equipped with an outer chimney body, an outer heat dissipation ring, heat dissipation fins, an inner chimney body, a heat dissipation protective layer, and a serpentine cooling pipe. When the smoke itself has a high temperature and transfers heat to the inner chimney body, the heat dissipation protective layer attached to the outside of the inner chimney body enhances the heat dissipation effect of the inner chimney body, allowing the high temperature of the smoke to be quickly transferred out of the inner chimney body. The transferred temperature is first cooled down by the coolant in the serpentine cooling pipe. The remaining temperature is transferred to the outer chimney body, where the outer heat dissipation ring can be installed on the outside of the outer chimney body through sliding grooves and sliding blocks. The multiple sets of heat dissipation fins on the outer heat dissipation ring enhance the heat dissipation capacity of the outer chimney body, quickly dissipating the remaining temperature. This combination gives the metal chimney excellent heat dissipation performance, avoiding the accumulation of high temperature inside the inner chimney body due to the heat dissipation capacity of the metal chimney itself, which could lead to metal fatigue, overheating deformation, or even burnout. This also ensures the normal emission of smoke from the metal chimney and improves the overall service life.

[0017] This utility model is equipped with fixing bolts, activated carbon filter, inner fixed filter frame, upper connecting filter and inner filter bag. When the device is used to discharge smoke normally, the smoke entering the inner chimney first passes through the first activated carbon filter to reduce the toxic and harmful factors in the smoke. Then, the smoke passing through the first activated carbon filter passes through the inner fixed filter frame and is filtered a second time by multiple sets of inner filter bags to further reduce the toxic and harmful factors in the smoke, so that the smoke meets the emission standards. Finally, it passes through the last activated carbon filter at the top to complete the three-stage filtration, allowing the device to be used safely in the outside world to complete the smoke discharge work and reduce the pollution of the atmosphere caused by smoke.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The metal chimney shown has excellent heat dissipation performance, including an outer chimney body 1 for providing protection for internal pipes;

[0028] A sliding groove 6 is formed on the outside of the outer chimney body 1 for installing heat dissipation components. A sliding block 7 is movably connected inside the sliding groove 6. An outer heat dissipation ring 8 is fixedly installed at one end of the sliding block 7, and heat dissipation fins 9 are fixedly installed on the outside of the outer heat dissipation ring 8.

[0029] The inner chimney body 10 is located inside the outer chimney body 1 and is used to carry the flow of smoke and dust. The outer surface of the inner chimney body 10 is covered with a heat dissipation protective layer 11. A serpentine cooling pipe 12 is fixedly installed on the outside of the inner chimney body 10. A leak-proof pipe plug 13 is fixedly installed at one end of the serpentine cooling pipe 12. The heat dissipation protective layer 11 attached to the outside of the inner chimney body 10 enhances the heat dissipation effect of the inner chimney body 10, allowing the high temperature of the smoke to be quickly transferred out of the inner chimney body 10. The transferred temperature is first cooled down by the coolant in the serpentine cooling pipe 12. The remaining temperature is transferred to the outer chimney body 1, and an outer heat dissipation ring 8 can be installed on the outside of the outer chimney body 1 through the sliding groove 6 and the sliding block 7. Multiple sets of heat dissipation fins 9 on the outer heat dissipation ring 8 enhance the heat dissipation capacity of the outer chimney body 1 and quickly dissipate the remaining temperature.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a mounting base 2 is fixedly installed at the bottom of the outer chimney body 1. A stiffening rib 3 is provided above the mounting base 2, and a positioning bolt 4 passes through the top of the mounting base 2. A chimney top 5 is fixedly installed at the top of the outer chimney body 1. The chimney top 5 facilitates the installation of the device outdoors, preventing rainwater from falling into the outer chimney body 1 and providing convenience for the device. The outer heat dissipation ring 8 is movably connected to the outer chimney body 1. The sliding groove 6 and the sliding block 7 work together to install the outer heat dissipation ring 8 on the outside of the outer chimney body 1 through the sliding groove 6 and the sliding block 7. The multiple sets of heat dissipation fins 9 on the outer heat dissipation ring 8 enhance the heat dissipation capacity of the outer chimney body 1 and quickly dissipate the remaining temperature. The inner chimney body 10 is tightly fitted with the heat dissipation protection layer 11. The heat dissipation protection layer 11 is made of graphene. The heat dissipation protection layer 11 attached to the outside of the inner chimney body 10 enhances the heat dissipation effect of the inner chimney body 10, allowing the high temperature of the smoke to be quickly transferred out from the inner chimney body 10.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a fixing bolt 14 passes through the exterior of the inner chimney body 10. One end of the fixing bolt 14 is movably connected to an activated carbon filter 15. The smoke entering the inner chimney body 10 is first filtered by the first activated carbon filter 15 to reduce the toxic and harmful factors in the emitted smoke. An inner fixed filter frame 16 is provided inside the inner chimney body 10. An upper connecting filter 17 is fixedly installed on the top of the inner fixed filter frame 16. An inner filter bag 18 is provided inside the inner fixed filter frame 16. When the smoke passing through the first activated carbon filter 15 passes through the inner fixed filter frame 16, it is filtered a second time by multiple sets of inner filter bags 18 to further reduce the toxic and harmful factors in the smoke, so that the smoke meets the emission standards.

[0032] The working principle of this device is as follows: Before use, first open the leak-proof plug 13 of the serpentine cooling pipe 12 and inject an appropriate amount of coolant into it. Then, install the outer heat dissipation ring 8 on the outside of the outer chimney body 1 through the sliding groove 6 and sliding block 7. Next, connect the device to the location or equipment where smoke emission is required through the mounting base 2, stiffening ribs 3, and positioning bolts 4. After the installation preparation is completed, smoke emission can be carried out normally. When the smoke enters the device, the smoke itself is at a high temperature. The heat dissipation protection layer 11 attached to the outside of the inner chimney body 10 enhances the heat dissipation effect of the inner chimney body 10, allowing the high temperature of the smoke to be quickly transferred out of the inner chimney body 10. The transferred temperature is first cooled down by the coolant in the serpentine cooling pipe 12. The remaining temperature is transferred to the outer chimney body 1, where the multiple sets of heat dissipation fins 9 on the outer heat dissipation ring 8 enhance the heat dissipation capacity of the outer chimney body 1, quickly dissipating the remaining temperature before it enters the outer chimney body 1. The smoke from the inner chimney body 10 first passes through the first activated carbon filter 15 to reduce the toxic and harmful factors in the emitted smoke. Then, the smoke passing through the first activated carbon filter 15 is filtered a second time by multiple sets of inner filter bags 18 when passing through the inner fixed filter frame 16, further reducing the toxic and harmful factors in the smoke, so that the smoke meets the emission standards. Then, it passes through the last activated carbon filter 15 at the top to complete the third filtration. In this way, the smoke is discharged normally, giving the metal chimney excellent heat dissipation performance. This avoids the situation where high temperature accumulates inside the inner chimney body 10 and cannot be discharged due to relying solely on the heat dissipation capacity of the metal chimney itself, which could lead to metal fatigue, overheating deformation, or even burnout. Finally, after completing the installation and use of the entire metal chimney according to the above operations, the coolant in the serpentine cooling pipe 12 needs to be replaced regularly. The heat dissipation protection layer 11 is made of graphene. In this way, the use process of the metal chimney with excellent heat dissipation performance is completed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
